[03:23:52] <miss0r2> bah... 3.5 meters of dovetail, and I'm still not done with the first 400mm
[03:24:51] <miss0r2> trying to make it act nice. I've never been a fan of dovetail cutters
[03:26:13] <miss0r2> also, the grind on this chinesium cutter is less perfect than I could've wished for
[03:30:27] <_unreal_> the dove tail keeps going and going and going :)
[03:31:05] <miss0r2> :]
[03:31:09] <miss0r2> sure feels like it
[03:31:32] <miss0r2> Normally for this type of application, I would have found some dovetailed extrutions that would fit my needs, but I couldn't on such short notice

[05:22:56] <jthornton> morning
[05:30:18] <XXCoder> morning
[05:37:04] <jthornton> you use inkscape?
[05:46:43] -!- holzjunkie has joined #linuxcnc
[05:48:32] -!- flyback has joined #linuxcnc
[05:50:53] <XXCoder> yeah
[05:50:57] <XXCoder> love it
[05:52:58] <jthornton> just installed it
[05:53:11] <XXCoder> first time or?
[05:54:47] <jthornton> I think I tried it a long time ago in like ubuntu 6 or 8
[05:55:40] <XXCoder> man inkscape have advanced a lot since then
[05:55:50] <XXCoder> first time I tried freecad it was crap lol
[05:56:00] <XXCoder> it was same for inkscape
[05:56:06] <XXCoder> except less crap
[05:57:53] <jthornton> how do you make a border on an object like a circle
[06:00:13] <XXCoder> ah! look at coloring page. click on bottom left area, see 2 tiny color squares?
[06:00:22] <XXCoder> new mdi window area should appear
[06:00:23] -!- veek has quit [Quit: Leaving]
[06:00:36] <XXCoder> it has 3 tabs, color, border color and border pattern
[06:02:18] <jthornton> https://imagebin.ca
[06:02:29] <jthornton> that's my lower left corne
[06:02:31] <jthornton> r
[06:03:32] <jthornton> ah I see now stroke must be defined
[06:08:57] <miss0r2> gaaah... I even see dovetails when I close my eyes!
[06:09:17] <miss0r2> 1.2 meters done.. 2.3 meters to go!
[06:09:40] <miss0r2> If I never see another dovetail again it will be too soon :]
[06:11:10] <XXCoder> look, a dovetail!
[06:11:24] <XXCoder> jthornton: ya must exist in order to color. :)
[06:12:10] <jthornton> I figured out the stroke line width was so small I could not see it
[06:12:18] -!- holzjunkie has quit [Ping timeout: 252 seconds]
[06:13:00] <XXCoder> its nice to be able to use no stroke
[06:13:02] -!- gloops has joined #linuxcnc
[06:13:06] <XXCoder> yo
[06:20:40] <Tom_L> yo
[06:20:41] <miss0r2> XXCoder: This is alot of dovetail cutting :) and its slow
[06:21:10] <XXCoder> fun
[06:21:53] <XXCoder> i made bunch of small parts. one part needs 4 tiny holes with half inch depth blown clear of chips.
[06:21:58] <XXCoder> i finished 65 of those.
[06:22:01] <XXCoder> thats lot of blowing.
[06:26:55] <miss0r2> lol yeah
[06:30:44] <XXCoder> tomorrow i look forward to same. yay...
[06:32:08] <miss0r2> hehe
[06:32:30] <miss0r2> This dovetail cutter has a poor grind. one flute is sticking out a bit... The sound is driving me nuts!
[06:33:05] -!- gloops has quit [Read error: Connection reset by peer]
[06:33:44] <miss0r2> This is taking entirely too long. I will have to come back in tonight
[06:34:40] <miss0r2> and I'm trying to figure out a good way to clamp this square profile here...
[06:35:31] <miss0r2> I need to tilt it 45 degrees. so I was just thinking of clamping it with two v-blocks, but I need to take alot off one side & then I would collide with the v-blocks
[06:36:09] -!- P1ersson has joined #linuxcnc
[06:37:03] <miss0r2> Either I come up with a clamping solution, or I have to rethink the part :)
[06:38:09] <miss0r2> if I put it in a v-block in the bottom of the vise, I will damage the sides clamping it.... AND THE RACKET FROM THE DOVETAIL CUTTING IS MESSING WITH MY CONSENTRATION
[06:38:10] <XXCoder> how about moving clamps?
[06:38:10] <miss0r2> :D
[06:38:31] <XXCoder> have m0 clamo finished end, remove clamps off unfinished
[06:39:22] -!- rmu has quit [Ping timeout: 244 seconds]
[06:39:27] <miss0r2> theres an added issue: I am going to leave the factory surface on most of the part, i.e. moving it around is out of the question, once I have started machining
[06:39:36] -!- rmu has joined #linuxcnc
[06:43:47] <miss0r2> basically small v-grooves on the vice would be nice just about now :)
[06:45:01] <XXCoder> ya my idea isnt moving part
[06:45:12] <XXCoder> its lamps shuffling
[06:45:30] <miss0r2> I have no idea:D
[06:46:06] <XXCoder> pretty stright forward, have m0 where you clamp finished side then remove clamps blocking unfinished part
[06:46:27] <XXCoder> though might leave mark where tool cuts overlap
[06:46:30] <XXCoder> hmm
[06:46:42] <miss0r2> yeah, we don't want that... :)
[06:46:55] <miss0r2> This this is alot more about finish than precision
[06:47:06] <miss0r2> its a camera trolley
[06:48:40] <miss0r2> hmm. but since I will not be doing any hard machining on it, I think I can get away with some cardboard clamping :D
[06:49:25] <XXCoder> using cardboard to protect finish eh
[06:49:36] <miss0r2> well... the corners of the square profile
[06:49:44] <miss0r2> just to even out the pressure a bit.
[06:49:56] <miss0r2> I have some realy nice thick cardboard, that alot of my older tools came in
[06:50:46] <miss0r2> bleh! that cutter makes a horrible racket everytime it engages a new stepover.
[06:50:54] <XXCoder> lol
[06:51:08] <miss0r2> if they order more of these, I'll get a proper one
[06:51:13] <miss0r2> or a bucketfull for that matter
[06:51:26] <miss0r2> or even better; outsource :D
[06:51:30] <XXCoder> dont have grind setup?
[06:51:40] <XXCoder> ya sometimes outprocess is better but not always bleh
[06:51:55] <miss0r2> hehe. I do have a grinder, but I do not have an indexer for it
[06:51:59] <miss0r2> so, I don't grind tools
[06:52:23] <miss0r2> well.. it has 2-4-6-8 indexing. but this is a 10 flute cutter
[06:52:37] <XXCoder> yeah dont seem possible lol
[06:52:48] <XXCoder> 0 havw primes of 2 and 5
[06:53:09] <miss0r2> :]
[06:53:27] <miss0r2> And I don't much feel like making a huge setup taking all day to mount my indexing head on the grinder ect...
[06:53:31] <miss0r2> I just hope it lasts
[06:54:08] <XXCoder> yeah
[06:54:21] <miss0r2> only 4 more passes to go on this part & i'm halfway there
[06:54:23] <XXCoder> some tools just cant work well lol
[06:54:43] <miss0r2> a dovetail cutter is one of'em
[06:54:52] <XXCoder> i cant run certain job prep because of huge drill
[06:55:04] <XXCoder> coworker told me it sounds like few dogs fighting in mill.
[06:55:13] <miss0r2> haha
[06:55:24] <XXCoder> thankfully I can run next 2 steps fine,
[06:55:30] <miss0r2> nice
[06:55:38] <miss0r2> I don't have coworkers, so I come here to bitch and moan :)
[06:55:46] <XXCoder> that one prep is quite dangerous lol
[06:55:56] <miss0r2> what does it involve?
[06:55:58] <XXCoder> almost 2" drill thats 16 inches long
[06:56:37] <miss0r2> that a bigboy tool
[06:56:55] <XXCoder> now picture that with 70 in/lb clamping
[06:57:04] <XXCoder> it cant do much clamping strength or it will deform
[06:57:10] <miss0r2> :o
[06:57:17] <miss0r2> I would just shit myself and go home
[06:57:35] <XXCoder> and its not even to final diameter, it still need even bigger boring head
[06:57:43] <XXCoder> that one is 2 feet long
[06:58:03] <miss0r2> shit
[06:58:07] <XXCoder> so long its inch away from plastic screen in tool storage area
[06:58:22] <XXCoder> and tool change moves fast lol scary face stab feelings.
[06:58:24] <miss0r2> I don't suppose you are allowed to snap a photo of that?
[06:58:30] <XXCoder> nope
[06:58:43] <miss0r2> Figures :) sounds awesome though
[06:58:50] <XXCoder> its one of largest tools used in shop
[06:59:00] <XXCoder> most insane I have used was 1' facemill
[06:59:09] <XXCoder> with 6" extend
[06:59:15] <miss0r2> not for the faint of heart :D
[06:59:19] <XXCoder> its very heavy I can barely lift it
[06:59:30] <XXCoder> it cant be used in toolchange it'd rip stuff up
[06:59:33] <miss0r2> thats what 320mm ish?
[06:59:45] <XXCoder> roughly 300mm = 1 feet
[06:59:46] <miss0r2> hehe, most of the tools you speak off I couldn't even fit on the mill
[06:59:48] <miss0r2> alright
[07:00:12] <XXCoder> most tools is tame at shop
[07:00:19] <XXCoder> 1 inch, half inch etc
[07:00:30] <XXCoder> on the small end is 1/32 ball endmill lol
[07:00:40] <miss0r2> what is that in science?
[07:00:41] <miss0r2> :)
[07:00:59] <miss0r2> 0.8
[07:01:02] <miss0r2> hehe
[07:01:15] <miss0r2> I have a drawer here with endmills down to 0.07mm ball
[07:01:33] <miss0r2> I only keep the realy small ones for shits and giggles. I have no way of running them :)
[07:01:35] <XXCoder> ya never needed smaller. 1/16 I use a lot :P engraving stuff
[07:01:44] <XXCoder> I got idea for ya
[07:01:48] <XXCoder> engraving stuff lol
[07:01:57] <miss0r2> with a 0.07mm? hahaha
[07:02:03] <XXCoder> just use some epoxy and rerun surface
[07:02:16] <XXCoder> then you got cool fine engravings lol
[07:02:16] <miss0r2> thats 0.0027"
[07:02:20] <XXCoder> ya
[07:02:37] <miss0r2> man, I don't have thinghing that can spin remotely fast enough to get use of that
[07:02:51] <miss0r2> thinghing= anything
[07:03:12] <XXCoder> ya would need serious rpm
[07:03:27] <XXCoder> 1/16 I use 10,000 rpm something. robodrill is great for that.
[07:03:36] <miss0r2> the place I got a handfull from drives'em at 47k rpm
[07:03:52] <XXCoder> for small machine I do recommand robodrill though you need temperate control
[07:04:03] <miss0r2> wtf is robodrill?
[07:04:07] <XXCoder> and I always run a "blank" (no part) to warm machine properly
[07:04:19] <XXCoder> its machine brand name
[07:04:25] <XXCoder> pretty dumb name
[07:04:47] <miss0r2> I repair machines for a living, and I have never seen/heard of one before
[07:04:58] <miss0r2> Must not be big outside of the US
[07:05:17] <XXCoder> yeah. its designed to be able to be operated by cnc arms lol
[07:05:21] <XXCoder> load unload
[07:05:48] <miss0r2> one could argue most cnc machines are
[07:05:55] <miss0r2> but also to be used by an operator
[07:05:56] <miss0r2> :)
[07:06:05] <XXCoder> sorta
[07:06:15] <pink_vampire> miss0r2: "robodrill" is a fanuc brand
[07:06:20] -!- selroc has joined #linuxcnc
[07:06:25] <XXCoder> hey pink
[07:06:35] <XXCoder> the difference is door is not removed
[07:06:41] <miss0r2> ahh alright.
[07:06:44] <miss0r2> hello pink_vampire
[07:06:50] <XXCoder> doors is designed to be able to close and open by arms
[07:07:08] <selroc> hi pink
[07:07:26] <miss0r2> I was out repairing a cnc machine, where the robot falsely thought the door was open...
[07:07:36] <pink_vampire> hi
[07:07:43] <pink_vampire> i just waked up
[07:07:49] <XXCoder> good morning
[07:07:50] <miss0r2> lets just say; after it had done its job, there was an open door
[07:07:59] <miss0r2> err.. no door
[07:08:06] <XXCoder> ow heh
[07:08:24] <miss0r2> Starting the last pass on the current part now...
[07:08:33] <XXCoder> https://www.youtube.com
[07:09:05] <XXCoder> ones at place I work is not set to open like that, need addons
[07:09:31] <miss0r2> :D
[07:09:44] <miss0r2> bah... even on the springpass its running now it makes a racket when starting !
[07:10:03] <miss0r2> That cutter is going in the bin after this job is done
[07:10:36] <XXCoder> lol
[07:10:42] <XXCoder> https://www.youtube.com btw another type
[07:10:50] -!- P1ersson has quit [Ping timeout: 255 seconds]
[07:11:41] <jthornton> give the cutter to someone you don't like
[07:11:55] <XXCoder> or death metal band looking for that sound

[07:21:27] <miss0r2> XXCoder: This is the part fresh off the mill https://imgur.com
[07:21:47] <XXCoder> nice
[07:23:00] <miss0r2> 4 of those... I have another four units that are slightly less complicated and two semi complicated mounting plates.. I have to get this done by thursday, end of day, to get them annodized
[07:23:00] <jthornton> nice at least it's a male dovetail they are easier to machine than the slot
[07:23:16] <XXCoder> lol bet slot is a whole lot more fun
[07:23:17] <miss0r2> jthornton: indeed. The slots are much shorter
[07:23:36] <miss0r2> so, you can see I am somewhat in a rush here :)
[07:24:36] <XXCoder> nice! new unlisted clickspring video
[07:24:51] <XXCoder> "The Good The Bad and The Oiler"
[07:24:53] <XXCoder> lol
[07:25:25] <miss0r2> uhhh
[07:27:04] <XXCoder> i love pareon benefits heh
[07:27:24] <XXCoder> clickspring has one of best benefits for pareon. way more than others.

[07:36:56] <XXCoder> miss0r2: precision oil applicator apparently
[07:37:02] <XXCoder> 2 different kinds of oil
[07:39:33] <miss0r2> meh. can you link me?
[07:39:56] <XXCoder> not to unlisted one
[07:40:20] <XXCoder> the channel https://www.youtube.com
[07:41:29] <miss0r2> how do I go about finding an unlisted one?
[07:41:40] <XXCoder> be pareon supporter :)
[07:41:46] <miss0r2> bah..
[07:41:54] <XXCoder> though theres ways to google unlisted videos
[07:42:00] <XXCoder> never looked that up so dunno
[07:42:13] <miss0r2> can't be bothered. :)
[07:43:28] <XXCoder> https://www.patreon.com
[07:43:48] <XXCoder> lists to see what videos you can watch. and honestly it'd be one of better $1 you have spent.
[07:44:30] <miss0r2> I already waste enough time watching youtube... :)

[07:48:17] <miss0r2> those are just words to me :)
[07:48:37] <XXCoder> those is excellent youtube channels
[07:57:06] <miss0r2> I just don't have powerfull enough speakers to enjoy youtube videos while this dovetail cutter is running
[07:57:27] <XXCoder> captions ;)
[07:57:42] <miss0r2> hehe, try doing that on an AvE video xD haha
[07:58:52] <XXCoder> tried to watch some ave eh
[07:59:25] <miss0r2> This cutter wold not qualify as a scookum choocher
[07:59:53] <XXCoder> found something you could do while its all noisy http://www.bluemilkspecial.com
[08:00:23] <XXCoder> its star wars with lots of humor. sometimes adult (but not ntfw) humopr
[08:00:36] <XXCoder> the very second comic contains adult comic
[08:00:58] -!- holzjunkie has joined #linuxcnc
[08:01:32] <miss0r2> lol nice animation https://9gag.com
[08:02:10] <XXCoder> lol thats new. saw one where cat went out after
[08:02:56] <miss0r2> lol
[08:03:35] <XXCoder> if youre fan of star wars i HIGHLY recommand that webcomic
[08:03:39] <XXCoder> so many laughs
[08:04:41] * miss0r2 is reading it as we speak
[08:07:44] -!- Patang has joined #linuxcnc
[08:08:42] <miss0r2> lmaf with the kenny character inside of R2D2
[08:08:48] <XXCoder> indeed
[08:09:06] <XXCoder> rereading it myself. lopve that webcomic. you got large arcive, 2009 to 2019
[08:12:13] <miss0r2> nice. I can recommends three; they are old and two of'em has stopped... but they are still there: hackles, biggerthancheese & userfriendly. all of those are computer geek stuff, but quite amusing
[08:12:38] <miss0r2> lol, hackles ended janurary 2004
[08:13:12] <XXCoder> third one is known
[08:13:41] <XXCoder> first is also known
[08:13:48] <miss0r2> well, biggerthancheese is not realy about computers
[08:13:56] <miss0r2> but popculture & violence
[08:14:22] <XXCoder> bigger than cheese also ended
[08:14:27] <XXCoder> bu will read later
[08:14:51] <miss0r2> yeah, hackles & BTC has ended

[08:39:07] <pink_vampire> hi
[08:45:26] <miss0r2> I need a new enclosure solution for the cnc. The one I am currently running is loosing a little water all the time. When its been running non-stop for 8 hours its beginning to form puddles on the floor
[08:45:56] <jdh> catch pan + pump!
[08:46:59] <miss0r2> jdh: hehe, that would be quite impractical. it would have to measure 3x4 meters
[08:49:37] -!- holzjunkie has quit [Ping timeout: 245 seconds]
[09:00:22] <miss0r2> down to only missing 2x400mm dovetails to be cut now
[09:00:48] <miss0r2> This is taking too long, and I have to end my work day in a few moments. I will be back tonight to continue on this hellova deed

[10:07:36] <CNC_Brian> Guys, can anyone explain to what the "sudo make setuid" when building RIP actually does
[10:08:38] <CNC_Brian> If I move the compiled binaries between machines or clone the disk do I need to run this command again?
[10:08:54] <SpeedEvil> I have not read the specivfic docs. In general, it would be for making something run as a specified user, by manipulating the permissions on the binary.
[10:09:15] <SpeedEvil> Perhaps - if the permissions do not remain the same on restore.
[10:10:27] <CNC_Brian> getting some horrible latency figures when I copy file form my dev box down onto the pc running my machines.
[10:16:50] -!- Sabotender has quit [Ping timeout: 250 seconds]
[10:17:16] <rmu> CNC_Brian: normal copy operations, esp. over the net, won't work, you have to run it again or replicate owner/permissions manually
[10:17:27] <rmu> it: make setuid
[10:17:45] <rmu> "sudo make setuid" runs "make setuid" as root
[10:18:28] <rmu> make changes owner of the binary that needs to run with realtime to root and sets the "setuid" bit, so the binary runs as the owner (root) regardless of the user that invokes said binary
[10:21:44] <CNC_Brian> Ah ok
[10:22:00] -!- jerryq has quit [Ping timeout: 252 seconds]
[10:22:10] <CNC_Brian> So if I build on a dev machine I need to reset the permissions on the files

[10:35:19] -!- CNC_Brian has quit [Quit: Leaving]
[10:35:57] <rmu> depends on how you copy
[10:36:29] <rmu> in general, if you copy as user (not as root) you will net to re-set the permissions and owner
[10:36:53] <rmu> don't copy as root.

[11:28:20] <flyback> THEY DIDN'T have good starting caps back then
[11:28:32] <flyback> or windings that would tollerate stalled for a few seconds
[11:28:43] <flyback> so they spin the housing up first to put backspin on the shaft
[11:29:34] <pink_vampire> i love old technology
[11:29:47] <flyback> enjoy :)
[11:29:54] <flyback> oh I got something for you then
[11:30:04] <flyback> and no that's not a pickup line
[11:30:37] <flyback> https://www.youtube.com
[11:30:45] <flyback> tried to yrs to find a video of one of these
[11:30:52] <flyback> it's a dc motor on one side and ac on the other
[11:31:01] <flyback> it's how they did conversions before electronics
[11:32:17] <pink_vampire> the bearing housing look like forged metal
[11:32:32] <pink_vampire> maybe cast?
[11:32:41] <pink_vampire> it is amazing
[11:34:47] <flyback> could be I dunno sorry
[11:35:10] <flyback> they also had an insteresting side effect that is still used today although used with a system without brushes etc
[11:35:19] <flyback> the rotating mass stores a small amount of energy
[11:35:26] <flyback> which smooths out fluxutations
[11:35:35] -!- holzjunkie has joined #linuxcnc
[11:38:52] <flyback> rotary condensors
[11:39:07] <flyback> which is a special induction motor usually in a sealed env without a shaft
[11:39:13] <flyback> used to buffer fluxutations
[11:39:16] <flyback> they have ups's this way also
[11:39:20] <flyback> only last a min or so
[11:39:31] <flyback> but they can constant smooth power or load demands
[11:39:35] <flyback> without wearing out a battery
[11:41:30] <gregcnc> like a rotary phase converter?
[11:42:43] <pink_vampire> i know people use rotary converters to convert from 1 phase to 3 phase
[11:42:58] -!- holzjunkie has quit [Ping timeout: 245 seconds]
[11:43:11] <gregcnc> i would imagine it's the same concept, but no pahse conversion
[11:43:29] <pink_vampire> of course
[11:44:22] <gregcnc> any motor becomes a generator as soon as the input voltage drops below BEMF
[11:44:25] <pink_vampire> 2 din rails are empty!
[11:44:35] <gregcnc> just need a flywheel to store some energy
[11:47:26] <gregcnc> pink_vampire are you replacing everything?
[11:47:32] <flyback> gregcnc, pretty much
[11:47:41] <flyback> although they optimize it for energy storage
[11:47:48] <flyback> so the rotor might be composit etc
[11:48:40] <flyback> this one flywheel ups at a university is on the same shaft as a diesel genset
[11:49:00] <flyback> if they genset refuses to start they have a clutch to dump the flywheel into the genset
[11:49:09] <gregcnc> makes sense
[11:49:54] <flyback> the other big advantage to a composite rotor is if it shit itself
[11:49:58] <flyback> it turns to sand basically
[11:50:08] <flyback> not a solid chunk of metal flying into someone's face
[11:50:08] <pink_vampire> gregcnc: i'm rearranging stuff to make the wires go ij more logic way, and also adding a wire duct for the motor / high power stuff
[11:51:36] <gregcnc> you're talking modern high speed composite flywheel in a vacuum chamber?
[11:52:45] <flyback> yeah
[11:52:51] <flyback> for some rotary ups's
[11:52:54] <flyback> not all
[11:53:09] <flyback> I geuss the idea was a) for maximum energy storage b) less kill factor
[11:54:21] <gregcnc> the motors used are also designed to run at high speed and very high efficiency
[11:54:32] <flyback> yes
[11:54:34] <gregcnc> I think BLDC

[11:54:43] <flyback> yes

[14:50:41] <gloops> im not really sure lol, powered off - restarted, file not there
[14:50:54] <gloops> stupid to save it in temp folder
[14:51:36] <fragalot> have you attemped any form of file recovery
[14:51:46] <roycroft> so, folks, i'm aware that the folks on the knifemaking forums don't always have a good grasp of how things work, but there seems to be a repeated meme regarding motors for belt grinders that makes me wonder if i'm missing something
[14:51:51] <fragalot> assuming you've not used your pc too much since
[14:52:06] <fragalot> roycroft: what's that?
[14:52:08] <roycroft> the claim is that for a belt grinder a tefc motor is essential, and that nothing else will work for a long period of time
[14:52:15] <roycroft> the motor i just bought is odp
[14:52:26] <roycroft> but i plan on making a shroud for it
[14:52:33] <roycroft> to protect it from the grinding grit
[14:52:39] <gloops> fragalot ive already got a new mesh drawn
[14:52:49] <fragalot> tefc just lasts longer in a grinding dust environment
[14:52:56] <roycroft> the claim on the knife forums is that even with a shroud an odp motor will eventually get stuffed up with grit and failw
[14:52:58] <fragalot> and if you run it at a low RPM, you really do want the external fan
[14:53:07] <roycroft> while a tefc motor is immune to that
[14:53:25] <roycroft> i don't recall ever seeing a tefc motor that has a filter in it
[14:53:54] <fragalot> it's mosty the bearings that suffer
[14:53:56] <roycroft> it seems to me that while it does an effective job at keeping grit out that falls on the outside of the motor, if there is airborne grit a tefc will suck it in just as well as an odp motor will
[14:54:02] <fragalot> and brushes, if applicable
[14:54:02] <roycroft> am i wrong there?
[14:54:28] <roycroft> and if i make a shroud that goes around the motor it won't suck in as much dust as if i left it open
[14:54:29] <fragalot> the fan will, but the motor bearings are better protected in a tefc
[14:54:36] <roycroft> ok
[14:54:53] <roycroft> but if i put a filter on the air inlet side of the motor
[14:55:04] <fragalot> you increase life
[14:55:10] <roycroft> then my shrouded, filtered motor would probably protect the bearings better than an unfiltered tefc motor, right?
[14:55:16] <fragalot> assuming you don't block airflow too much when you run at low rpm
[14:55:21] <roycroft> i'd just have to check the filter and change it occasionally
[14:55:30] <roycroft> yeah, running at low rpm can be an issue
[14:55:46] <roycroft> i'm unlikely to run at low rpm for extended periods of time
[14:56:02] <roycroft> and if the motor starts getting hot i can always add an external fan (along with the filter)
[14:56:24] <fragalot> yep
[14:56:37] -!- R2E4 has quit [Quit: Going offline, see ya! (www.adiirc.com)]
[14:56:43] <roycroft> i got what i got because it was cheap and because it has a 56z frame
[14:56:54] <roycroft> the z meaning in this case 7/8" shaft
[14:57:20] <roycroft> most 3hp motors have a 1-1/8" shaft, which is problematic for mounting an off-the-shelf drive wheel
[14:57:30] <roycroft> so i'm good to go
[14:58:04] <roycroft> if i am sucking in a lot of grit into the shrouded motor i need to worry about sucking grit into the vfd as well
[14:58:31] <roycroft> i don't want to mount the vfd on the other side of the room
[14:58:36] <roycroft> i want it near the grinder
[14:58:54] <fragalot> be reasonable with the placement (ie. not under the belt) & just clean it out periodically
[14:59:00] <roycroft> i'm also likely to build a shield around most of the belt
[14:59:15] <roycroft> so that most of the grit will just go straight down toward the floor
[14:59:22] <roycroft> when the grinder is in the vertical position
[14:59:26] <fragalot> shoot it into a bucket & extractor
[14:59:29] <roycroft> yeah, it won't be near the belt
[14:59:33] <roycroft> right, that's what i'm thinking
[14:59:40] <roycroft> a bucket of water underneath the grinder
[14:59:51] <roycroft> and shield the belt except at the working bits
[15:00:03] <roycroft> it should shoot almost everything straight down into the bucket of water
[15:00:35] <roycroft> my current belt grinder does not shoot sparks and grit and crap all over the place
[15:00:41] <roycroft> that stuff mostly goes straight down
[15:01:07] <roycroft> the knifemaking forums can be interesting
[15:01:32] <fragalot> that's what happens when a single obervation becomes lore
[15:01:36] <roycroft> there's a lot of argument about motor size, with many folks claiming a 1/3hp washing machine motor is powerful enough for all grinding needs
[15:01:49] <fragalot> not important why, but this is how it is, because someone said so once
[15:01:49] <roycroft> and folks saying that a 3hp motor is insane
[15:02:11] <roycroft> i have this annoying personality trait of being fact and evidence driven
[15:02:12] <fragalot> 3hp is not insane if you want to be able to lean into it with a 20grit belt
[15:02:23] <roycroft> and never taking anecdotes as fact
[15:02:43] <roycroft> i think 3hp is the perfect size motor for it
[15:02:57] <roycroft> 2hp would be ok
[15:03:01] <roycroft> but 3hp will be better
[15:03:11] <roycroft> 5hp, that's getting into overkill imo
[15:03:33] <roycroft> and it's hard to find an affordable 5hp vfd with single phase input
[15:04:06] <roycroft> anecdotes are not to be rejected, btw
[15:04:15] <roycroft> they are research opportunities though, and not facts
[15:04:25] <fragalot> they are not to be rejected, but they are not to be repeated blindly
[15:04:34] <fragalot> or taken as the only truth
[15:04:36] <gloops> on the facebook group there is a strong school of thought in favour of 3hp
[15:04:46] <gloops> although many builds are much less
[15:04:57] <fragalot> you can get by with less
[15:05:00] <roycroft> yes
[15:05:06] <roycroft> i was going to build with the 2hp motor i have
[15:05:13] <roycroft> and 1hp would probably even get me by
[15:05:28] <roycroft> a fractional hp motor, imo, is not appropriate for a grinder the size i'm building
[15:05:31] <fragalot> my little belt grinder is something like 130W, and it gets the job done
[15:05:40] <fragalot> the only issue is that said job takes about 10 times longer
[15:05:44] <fragalot> if not more
[15:05:45] <gloops> 1.5-3 seems within acceptable parameters, less is not enough
[15:05:56] <roycroft> i am getting old
[15:06:01] <roycroft> i don't have as much time as i used to
[15:06:05] <fragalot> :D
[15:06:14] <roycroft> i need to make the most of the time that i have
[15:07:05] <roycroft> i say, having spent a full hour last night flattening the back of a single chisel
[15:07:10] <roycroft> and that job is not quite done yet
[15:07:25] <roycroft> i have another 10-15 minutes of lapping to do before it's truly flat
[15:07:57] <roycroft> a belt grinder could probably have gotten it mostly flat in a matter of a minute or two, leaving me with only 15 minutes or so of hand lapping
[15:08:23] <fragalot> it could have gotten it flatter, but in my experience belt grinders do not grind flat well
[15:08:26] <roycroft> fortuantely i do not get new chisels often, as i have most of what i ever need
[15:08:39] <roycroft> hand lapping will always be needed
[15:08:43] <fragalot> and i've found myself cheating & grinding the back of cheap chisels in the japanese style
[15:08:55] <fragalot> hollow it out, save yourself an hour of lapping
[15:09:01] <roycroft> yes, that's a great idea
[15:09:09] <roycroft> until you've been using the chisel for 20 years
[15:09:10] <fragalot> then again, i've quit buying shit chisels
[15:09:14] <roycroft> and have honed it back to the hollow
[15:09:28] <fragalot> then that chisel has served you well & you deserve an upgrade
[15:09:28] <roycroft> i have some japanese chisels that are useless because of that
[15:09:52] <roycroft> most of my chisels are robert sorby
[15:09:54] <fragalot> also, if you can't get it to work again, the hollow was too deep
[15:10:02] <roycroft> folks complain about them because they're not as hard as some
[15:10:13] <roycroft> but i've found that they work very well
[15:10:24] <roycroft> and i don't mind that i need to hone them more often than harder ones
[15:10:30] <roycroft> they never chip out
[15:10:35] <roycroft> and are easy to hone
[15:10:43] <roycroft> we're not talking about a big difference
[15:10:49] <roycroft> sorby are around rockwell 61
[15:10:57] <fragalot> i've got a selection of japanese, 2 cherries, MGH, and the ultra cheap yet pretty damn good no-name beaters
[15:11:08] <roycroft> the "hard" chisels to which folks compare them are usually rockwell 62 or 63
[15:11:21] <roycroft> some japanese chisels are rockwell 64 at the working end
[15:11:26] <gloops> i just got used to being called 'rough' lol
[15:11:34] <fragalot> with ultra cheap i'm talking €1 for a 12mm chisel, that actually works really well
[15:11:34] <roycroft> i just got some 2 cherries skew chisels
[15:11:39] <roycroft> 12mm
[15:11:41] <roycroft> left and right
[15:11:46] <roycroft> those are the ones i'm working on right now
[15:11:49] <roycroft> the steel is good
[15:12:04] <roycroft> but 2 cherries very annoyingly buff their chisels to a mirror finish
[15:12:13] <roycroft> but they don't grind them flat first
[15:12:16] <fragalot> you can buy them ground
[15:12:27] <roycroft> and the buffing rounds them over a bit
[15:12:40] <roycroft> i knew going in that i'd have to reshape them before i could use them
[15:12:55] <roycroft> i looked for unpolished ones
[15:12:56] <fragalot> that's why you buy the ground ones, not the polished ones :P
[15:13:02] <gloops> https://www.ebay.co.uk
[15:13:03] <roycroft> it's really hard to find unpolished skew chisels
[15:13:20] <roycroft> so i got what i could get
[15:13:27] <fragalot> roycroft: https://www.fine-tools.com
[15:13:28] <gloops> stuff like that is on ebay endlessly, all the old chisels are far superior to modern ones
[15:13:31] <roycroft> and planned on doing a lot of lapping and honing before they would be useful
[15:13:56] <roycroft> old sheffield steel chisels are great
[15:14:12] <roycroft> fragalot: those chisels are not in the usa
[15:14:24] <gloops> £1 each on the car boot sale near me (15 mile from sheffield)
[15:14:32] <roycroft> i should preface my previous statement by saying that in the usa it's hard to find unpolished 2 cherries skew chisels
[15:14:38] <fragalot> roycroft: Welcome to getting useful links that aren't very useful. :)
[15:15:03] <roycroft> i would love to go on a car boot sale trip to the uk
[15:15:12] <roycroft> i would find so much amazing stuff for so cheap
[15:15:23] <fragalot> I would love to go to a swap meet that keith rucker & abom appear to find
[15:15:42] <fragalot> or the auctions
[15:15:49] <gloops> https://www.ebay.co.uk i might have a go at those
[15:15:52] <roycroft> anyway, i got what i got
[15:15:59] <roycroft> and they're polished
[15:16:06] <roycroft> or soon to be were polished :)
[15:16:18] <roycroft> one of them has a back that is no longer polished, but it is almost flat now
[15:16:30] <gloops> big one is f... though
[15:17:00] <roycroft> https://www.amazon.com
[15:17:07] <fragalot> roycroft: I remember spending 3 days lapping my stainly €4 plane
[15:17:09] <roycroft> that's one of my moritse chisels
[15:17:10] <fragalot> #4*
[15:17:19] <roycroft> i like big, beefy mortise chisels
[15:17:20] <fragalot> my arms hated me
[15:17:27] <roycroft> and that thing is a monster
[15:17:28] <fragalot> and it's still not flat >.>
[15:18:03] <roycroft> the thing is, fragalot, you should only have to do that once ever
[15:18:04] <roycroft> per tool
[15:18:38] <fragalot> in my opinion you shouldn't even need to do it once
[15:18:45] <fragalot> the fact that you do sickens me
[15:18:52] <roycroft> yeah
[15:18:54] <roycroft> and i get why
[15:18:58] <roycroft> i don't agree, but i get it
[15:19:06] <fragalot> tuning up, fine
[15:19:14] <fragalot> but having to rough it down.. no.
[15:19:18] <roycroft> modern toolmakers do all their grinding before heat treating, because it's easier to do while the steel is still soft
[15:19:43] <roycroft> so it's cheaper to manufacture that way
[15:19:46] <roycroft> and that's fine
[15:20:02] <gloops> the irons in the old wooden planes are often superb, you can get a scary edge on them
[15:20:04] <roycroft> it would be nice to have the option of getting tools that are ground after heat treatment
[15:20:11] <roycroft> they are, gloops
[15:20:16] <gloops> plus 3 times thicker
[15:20:19] <roycroft> especially norris and spiers
[15:20:35] <roycroft> but some modern steels are even better than the old-time stuff
[15:20:49] <roycroft> lie-nielsen use a2 steel that's cryogenically treated
[15:20:53] <gloops> at a cost roycroft
[15:20:55] <roycroft> and their plane irons are amazing
[15:20:57] <roycroft> yes
[15:21:05] <fragalot> I quite like the axminster rider planes
[15:21:09] <fragalot> and veritas
[15:21:14] <roycroft> lee valley/veritas use some fancy new alloy that costs 2x as much as the good a2 stuff
[15:21:20] <fragalot> both are very decent, but not extortionately priced
[15:21:23] <pink_vampire> gloops: I'm sorry that i'm on and off like that today, I'm working on the panel the same time
[15:21:57] -!- syyl has joined #linuxcnc
[15:22:09] <roycroft> i really like lie-nielsen planes for modern planes
[15:22:09] <fragalot> roycroft: thing is though, a lot of tools you buy today aren't even ground flat.. it's just been pushed up to a belt sander by hand to make it look nice
[15:22:13] <gloops> oh its no problem pink_vampire, i know youre busy :)
[15:22:14] <roycroft> they are expensive but they are amazing
[15:22:39] <fragalot> my table saw for example looks like they basically used a handheld flapwheel to surface it
[15:22:43] <roycroft> or the 2 cherries that are rough ground, lightly honed, and then polished with the grinding marks left on
[15:22:55] -!- holzjunkie has joined #linuxcnc
[15:23:03] <roycroft> make them smooth before polishing them, mmkay?
[15:23:44] <roycroft> actually, just keep them the hell away from a polishing wheel
[15:24:02] <fragalot> yeah
[15:24:07] <roycroft> do final honing on a japanese water stone and you'll get a mirror finish without using a polisher
[15:25:10] <fragalot> I used to do that too until i found that I couldn't tell the difference very well between doing up to a 12k stone, or going straight from 2k to a CrOx leather strop
[15:25:14] <roycroft> anyway, the belt grinder would save me some of the initial time flattening
[15:25:24] <roycroft> but certainly not all of it
[15:25:24] <fragalot> s/crox/white polishing compound)
[15:25:43] <roycroft> i was essentially doing shaping on the diamond plate last night, not sharpening
[15:25:46] <fragalot> for the back I still use the stone, but for the cutting edge... eh.
[15:26:07] <roycroft> i use dmt diamond plates for initial sharpening
[15:26:13] <fragalot> same
[15:26:15] <roycroft> i have x-coarse, coarse, medium, and fine
[15:26:17] <roycroft> i go through all those
[15:26:33] <roycroft> and when i'm done with the fine plate i move over to an 8000 grit japanese waterstone
[15:26:45] <fragalot> I don't any more, just medium, fine, strop, done.
[15:26:48] <roycroft> from there i do final stropping on leather
[15:27:10] <fragalot> is there a difference in sharpness? probably. can I tell the difference personally? not really.
[15:27:12] <roycroft> after the intial sharpening i usually just touch up on the water stone and lap
[15:27:23] <roycroft> the diamond plates are just for initial sharpening
[15:27:55] <roycroft> after the microbevel gets too big from honing too many times i go back to the diamond plates to reestablish it
[15:28:27] <roycroft> i like to grind both plane irons and chisels at 25 degrees, and then put a 27 degree microbevel on them
[15:28:56] <fragalot> another thing I don't bother with is sharpening jigs once the edge is nice & square
[15:29:03] <roycroft> the big mortise chisels i grind at 30 degrees with a 32 degree microbevel
[15:29:08] <fragalot> I don't mind a slight camber
[15:29:17] <roycroft> i have the lie-nielsen jig
[15:29:18] <roycroft> it's nice
[15:29:23] <roycroft> very expensive, but works brilliantly
[15:29:30] <roycroft> it makes it so that i don't have to even think about it
[15:29:46] <fragalot> i've got the veritas one
[15:29:47] <roycroft> i just stuff the blade in the jig, set it to the desired angle, and go
[15:29:49] <roycroft> it's very fast
[15:29:55] <roycroft> i have the mark i
[15:29:59] <roycroft> but not the mark ii
[15:30:00] -!- jerryq has quit [Ping timeout: 252 seconds]
[15:30:07] <roycroft> the mark i will be useful for the skew chisels
[15:30:17] <fragalot> I only really use the jig for new or really bad chisels
[15:30:23] <roycroft> but i don't like top clamp jigs - too easy for the blade to move
[15:30:44] <fragalot> during normal use & touch-ups I just freehand it & don't even fret too much about the exact angle
[15:30:45] <roycroft> and the eclipse is just too sloppy to work well
[15:30:59] <fragalot> just go for it paul sellers style
[15:31:05] <roycroft> the lie-nielsen is basically the eclipse design done to machinist standards
[15:31:13] <fragalot> hehe
[15:31:21] <roycroft> and it's made of stainless steel
[15:32:01] <roycroft> https://www.lie-nielsen.com
[15:33:08] <roycroft> very expensive, but worth every penny
[15:34:04] <roycroft> and if you consider that i have over $400 invested in those diamond plates, $250 for a jig and all the extra jaws i needed for it isn't totally out of line
[15:34:45] <fragalot> yea I think i've got over 2 grand in a drawer in just sharpening materials
[15:34:50] <fragalot> it gets out of hand quick :D
[15:35:56] <roycroft> i bought the jet clone of the tormek sharpener years ago
[15:36:00] <roycroft> i really never used it much
[15:36:03] -!- holzjunkie has quit [Ping timeout: 252 seconds]
[15:36:10] <roycroft> i don't like hollow grinding my tools
[15:36:36] <roycroft> especially ones that i use a lot - hollow grinding weakens the edge
[15:36:40] <fragalot> i'm not sure i'd mind, with the way I hand sharpen after
[15:36:54] <fragalot> which usually ends up with a slight convex grind
[15:37:21] <roycroft> i'd rather spend more time grinding a good, solid edge and keeping it honed well
[15:37:36] <fragalot> and in your case if you jig it up, you wind up with a faster flat bevel where it matters
[15:37:43] <roycroft> all hollow grinding does is save time up front on the initial sharpening
[15:37:48] <fragalot> and from a practical standpoint, i'm not sure if it is still really weaker at that point
[15:38:03] <roycroft> and imo that does not offset the weakening of the edge that it introduces
[15:38:08] <roycroft> so i'll probably sell that jet
[15:38:21] <fragalot> also, if you set the angle right, i'm also not convinced the hollow grind is any weaker
[15:38:28] <fragalot> assuming the start of it has the same 25°
[15:38:29] <roycroft> right now, all i use it for is the initial grind when i have to reshape an edge
[15:38:49] <roycroft> i'll get it square and ground roughly to the correct angle with the jet
[15:39:01] <roycroft> then i'll take it to the diamond plates and put a proper flat edge on it
[15:39:17] <roycroft> for paring and light duty chisels it's not a big deal
[15:39:20] <roycroft> nor with plane blades
[15:39:32] <roycroft> it's with those big mortising chisels where it really weakens the edge a lot
[15:39:41] <fragalot> I mortise with my "light duty chisels"
[15:39:44] <roycroft> but i really wail on those chisels with a large mallet
[15:39:46] <fragalot> never had any problems
[15:40:08] <roycroft> anyway, it is lunch time
[15:40:10] <fragalot> not since using that method paul sellers showed in his video
[15:40:45] <fragalot> roycroft: https://www.youtube.com <-- this is the method I use
[15:41:50] <roycroft> i'll check it out after lunch
[15:42:00] <roycroft> paul sellers is a good woodworker and a good instructor
[15:42:01] <fragalot> enjoy
[15:42:07] <roycroft> i always enjoy watching him
[15:42:20] <roycroft> but for now mah belly needs filling

[16:56:52] <roycroft> so my method of cutting mortises is similar to what paul sellers does
[16:56:59] <roycroft> with a couple differences
[16:57:10] <roycroft> i don't cut right to the edges of the mortise on the first go
[16:57:28] <roycroft> i like to chop out the mortise, leaving a tiny bit on all sides for cleanup
[16:57:37] <roycroft> then i pare down at the knife line
[16:57:55] <roycroft> i also have a swan-neck chisel for scooping the gunk out of the mortise
[16:58:02] <roycroft> and i prefer that to using a smaller chisel
[16:58:09] <roycroft> both are minor variations
[16:58:26] <roycroft> i've never chopped mortises starting in the middle and working to both ends
[16:58:34] <roycroft> i have always started at one and and worked to the other
[16:58:49] <roycroft> i don't remember how/why i started doing it that way
[16:58:59] <roycroft> but i don't think i've ever done it any other way

[17:38:02] <Tom_L> how do you clone a linux hdd?
[17:38:18] <Tom_L> i wanna copy what i've got to a test drive to update to 2.8
[17:38:58] <JT-Shop> you just make a copy of the ~/linuxcnc directory
[17:39:18] <JT-Shop> and all the subdirectories under linuxcnc
[17:39:27] -!- flyback has joined #linuxcnc
[17:39:56] <Tom_L> i wanna keep wheezy too
[17:42:34] <roycroft> you're wanting to clone the entire disk to a fresh disk?
[17:42:44] -!- R2E4 has joined #linuxcnc
[17:42:57] <R2E4> evening, morning,afternoon
[17:43:16] <JT-Shop> Tom_L: explain what your wanting to do
[17:43:41] <Tom_L> clone the whole hdd to another one
[17:43:46] <roycroft> ok
[17:43:51] <Tom_L> i may just use ghost
[17:44:05] <JT-Shop> dd or what is that software hmmm
[17:44:05] <roycroft> debian, and debian-like operating systems use multiple partitions for the os
[17:44:13] <roycroft> easiest would be to boot from a livecd
[17:44:14] <roycroft> then
[17:44:16] <R2E4> can someone help with halui.max-velocity? Im trying to set jog speed for external buttons. nothing I am trying is working. it is set to 20 by halui.max-velocity.value
[17:44:27] <JT-Shop> Tom_L: you don't have an extra hd?
[17:44:33] <Tom_L> i do
[17:44:37] <Tom_L> several probably
[17:44:44] <roycroft> dd if=/dev/rsda of=/dev/rsdb bs=2m
[17:44:55] <JT-Shop> just copy your config and swap drives
[17:44:56] <roycroft> you want to copy the raw devices
[17:45:00] <roycroft> not the block special devices
[17:45:07] <roycroft> so make sure it's /dev/rsda, not /dev/sda
[17:45:30] <roycroft> your /boot will be in sda1
[17:45:32] <JT-Shop> R2E4: can you paste.ubuntu.com what you've tried
[17:45:35] <roycroft> root usually in sda2
[17:45:36] <roycroft> etc.
[17:45:43] <Tom_L> next part of it is: will it being a ssd matter?
[17:45:46] <roycroft> but rsda would be the whole disk
[17:45:57] <roycroft> it might
[17:46:19] <roycroft> but i think ssds do their remapping magic transparently, in which case it doesn't matter
[17:46:31] <R2E4> The machine is in the other building not on network yet.
[17:46:39] <roycroft> other than that it will go a lot faster than if is it were not an ssd
[17:46:58] <roycroft> make 100% certain you know which disk is your source drive
[17:47:03] <R2E4> but: setp jog-speed 200, setp halui.axis.jog-speed 200
[17:47:05] <roycroft> and do not accidently write to it
[17:47:16] <roycroft> i am now not responsible for anything you do :)
[17:47:24] <Tom_L> yeah i've done this type of thing before
[17:47:28] <JT-Shop> R2E4: http://wiki.linuxcnc.org
[17:47:38] <roycroft> but what's important is that you do not try to do it using the live os
[17:47:38] <JT-Shop> that's how I set jog speed on my pendant
[17:47:44] <roycroft> that's why i said to do it from a livecd
[17:47:57] <roycroft> bs=2m can be whatever you want, actually
[17:48:18] <roycroft> it's just a lot faster to read/write in big chunks like that instead of physical sector by physical sector
[17:48:25] <roycroft> faster by maybe two orders of magnitude
[17:48:53] <TurBoss> pv -tpreb /dev/sda | dd of=/dev/sdc
[17:48:54] <TurBoss> shows progress
[17:49:48] <roycroft> or just trust that it's doing the right thing :)
[17:50:10] <roycroft> if the source is a ssd then there is not going to be all that much to clone anyway
[17:50:26] <roycroft> probably 128GB or so
[17:50:31] <roycroft> that won't take very long
[17:50:36] <roycroft> even 1TB won't take all that long
[17:50:51] <roycroft> just start the copy and go have a refreshing beverage while waiting for it complete :)
[17:51:21] <R2E4> jthornton: halui.jogspeed doesnt exist anymore halui.axis.jog-spped is what is used, and I have tried setting that.
[17:52:24] <JT-Shop> hmm did you try setting it from the show hal window?
[17:52:38] <JT-Shop> looks like someone added a dash in the name lol
[17:52:47] <R2E4> no, didnt know you couold...lol I checked it from there....
[17:53:10] <JT-Shop> no, I have it right it's jog-speed in my example
[17:53:38] <JT-Shop> yea you can just set the pin with setp pin-name value
[17:53:49] <JT-Shop> it won't get saved but good to test with
[17:53:59] <R2E4> yeah, thats my bad but its not halui.jog-speed, it doesnt exist
[17:54:13] <R2E4> ok. Ill try that
[17:54:45] <JT-Shop> I'll take a look downstairs I have master running down there but first I need to finish wiring up the generator before dark

[18:24:34] <jthornton> are you using joint plus/minus to jog
[18:24:58] <R2E4> jog-x-plus /minus
[18:25:35] <jthornton> axis jog won't work in joint mode only world mode

[18:26:33] <R2E4> my paste: https://paste.ubuntu.com
[18:27:24] <R2E4> it seems you cant set it while it is connected to signal jog-speed
[18:28:03] <R2E4> But I dont want to have to set it then connect after axis is running
[18:28:06] <jthornton> are you doing a setp while it's connected to a signal?
[18:28:23] -!- togo has quit [Ping timeout: 258 seconds]
[18:28:25] <R2E4> yeah, I see you cant....now
[18:28:42] <jthornton> first you have to unlink then you can setp
[18:28:58] <R2E4> I tried setting it before it gets connected and it didnt work
[18:29:23] <jthornton> as soon as it get connected to something it takes that value
[18:29:40] <R2E4> so unlink=>setp=> net ?
[18:30:11] <jthornton> http://linuxcnc.org
[18:30:34] <jthornton> http://linuxcnc.org
[18:30:40] <R2E4> So it should work if I setp before it gets connected. Thats what I tried and it didnt work
[18:32:58] <jthornton> just to be clear your setting the joint jog speed and using the joint jog plus/minus?
[18:34:24] <R2E4> no the axis, joint is for joint mode before I home.
[18:34:30] <R2E4> is my understanding
[18:35:42] <jthornton> one thing I just verified is you can halui axis jog an axis unless it's homed
[18:36:32] <jthornton> I have no problem changing the speed using halui.axis.jog-speed
[18:36:38] <R2E4> yes thats right. I want to use the buttons after I home. so it is halui.axis.jog-speed
[18:36:57] <R2E4> which is connected to jog-speed signal and it gets set to 20
[18:37:27] <jthornton> how are you changing the halui axis jog speed?
[18:38:30] <R2E4> I am not, thats the problem, its at 20 because thats what is default. If you look at jog-speed in halshow you see that it is connected to two pins,
[18:38:41] <jthornton> default is 0
[18:38:52] <jthornton> which pins?
[18:39:10] <R2E4> my jog-speed is 20
[18:39:38] <R2E4> halui.axis.jog-speed and halui.max-velocity.value
[18:40:15] <jthornton> what is the net line for halui.axis.jog-speed
[18:43:24] <R2E4> net jog-speed halui.axis.jog-speed
[18:43:47] <jthornton> what else is connected to the jog-speed signal?
[18:44:55] <R2E4> jog-speed in halshow shows jog-speed => halui.axis.jog-speed <= halui.max-velocity.value
[18:45:36] <R2E4> halui.max-velocity.value is set to 20 somewhere, probably hardcoded as default which is my guess
[18:46:14] <jthornton> why is halui.max-velocity connected to jog speed?
[18:47:05] <jthornton> it's not hard coded if not connected to anything halui.max-velocity is 1
[18:48:48] <R2E4> I dont have halui.max-velocity.value anywhere in my hal files
[18:49:54] <jthornton> it's got to be in there somewhere open a terminal in your configuration directory and do grep -irl 'halui.max-velocity' *
[18:56:22] <jthornton> using a couple of pyvcp buttons and a checkbox this works to set jog speed https://paste.ubuntu.com
[18:59:00] <R2E4> jthornton: I am always wrong...... halui.max-velocity.value was connected in xhc wireless pendant hal file...... dOH!!!

[21:46:13] <Tom_L> nice
[21:50:27] <miss0r2> you ever know the feeling, that this will be a long day? :)
[21:57:39] <tiwake> trying to get my work place to buy one of these https://www.darex.com
[21:58:02] <tiwake> they have a drill sharpener, but I can sharpen drills by hand better than the piece of crap that is there

[22:16:50] <weenerdog> i have not

[22:21:49] <miss0r2> hehe, its fun to see what people are in here at this hour :) Not people i would normally see in my "daytime hours"
[22:23:09] <cncnoob> Howdy. I've never run a lathe before, but wanted to get one that I could grow into. I would perform a CNC conversion on it right when I got it. I read a lot of good things about South Bend lathes, and also see there are some conversion kits out there if I decide not to make my own. Any thoughts on what to watch out for, or what price to expect?
[22:23:20] <cncnoob> I was looking at this one, but it seems like the price might be a bit high:

[22:41:29] <skunkworks> cncnoob: not this one? https://kansascity.craigslist.org
[22:42:42] -!- veek has joined #linuxcnc
[22:42:48] <cncnoob> That is a bit big
[22:43:06] <cncnoob> also not a south bend, which is what I've been doing all my research on thus far
[22:43:19] <cncnoob> If there is a better option for a CNC conversion I'm open to suggestions.
[22:43:42] <weenerdog> research shmesearch :)
[22:43:46] <jdh> already cnc is better than convert to cnc
[22:44:01] <cncnoob> Humm, I guess
[22:44:12] -!- veek has quit [Remote host closed the connection]
[22:44:17] <cncnoob> Good thing about doing conversions yourself is that you learn about the machine in the process
[22:44:55] <jdh> you could probably sell the control or parts for the cost of the lathe
[22:46:48] <tiwake> cncnoob: just see if the ways are good is the main thing, if you are getting a used machine
[22:47:06] <weenerdog> i got a stupid question i cant find an answer for... when you order cheap ass ballscrews, is the length just the threaded part, or the whole thing?
[22:47:28] <tiwake> honestly you can get a CNC machine for really cheap, a lot of times for the same price of a manual.. sometimes cheaper
[22:49:17] <tiwake> I think we bought the okuma CNC lathe for $5,000
[22:49:35] <tiwake> weighed 10k lbs
[22:50:16] <tiwake> might have been less
[22:50:21] <tiwake> like $3,000
[22:50:30] <tiwake> I don't exactly recall
[22:50:45] <tiwake> good machine
[22:51:10] <tiwake> I bought a hardinge CHNC lathe for $500
[22:51:21] <tiwake> that one needs a controller built for it though
[22:52:05] <tiwake> going to be building my first linuxCNC controller finally... probably going to start on that sometime this summer

[23:20:44] <cncnoob> A lot of the machines that can be had at a decent price are huge
[23:21:02] <cncnoob> I'll be putting the machine in question in my 3 car garage
[23:21:15] <cncnoob> I don't have room for something that weighs 10k lbs :)
