[04:36:32] <XXCoder> hey Deejay gloops
[04:37:19] <gloops> hi
[04:37:54] <Deejay> hey
[04:38:45] <gloops> looking at cutters, finding some limitations for the scroll saw pattern for the bee i bought
[04:39:09] <gloops> 2mm endmill only comes in 15mm length, so cant make it deeper than that
[04:39:10] -!- asdfasd1 has joined #linuxcnc
[04:40:49] <XXCoder> unless you order custom heh $$$
[04:41:09] <XXCoder> work uses very few custom tools, one of em were a very long tapping tool for diameter
[04:41:39] <gloops> yeah i wouldnt go with expensive stuff, not for something im likely to break a lot of lol
[04:41:50] <gloops> 15mm is okish, 20 would have been better
[04:42:19] <gloops> just shows she is pretty good with the scroll saw hers are 3/4 inch

[05:30:57] <PL7icnc> somone here from Mesanet
[05:31:02] <PL7icnc> pcw_home,
[05:31:40] <PL7icnc> pcw_mesa, Are You Online
[05:33:16] <rmu> hmm
[05:33:34] <rmu> PL7icnc: you don't need permission to ask questions
[05:34:59] <PL7icnc> is there a Sign on the 7i76e Showing Source or Sinking as the Images in Store are the same
[05:36:05] <PL7icnc> 5i25/7i76 can i mesurer if the ports Out are OK seams as EMV has killed a complete outBank
[05:40:06] <rmu> i guess the difference is just the output driver chip(s)
[05:43:06] <rmu> in any case the sinking version should be marked 7I76ED
[05:44:48] <PL7icnc> the images in the mesastore shoudt indicate that
[05:45:15] <PL7icnc> or can i change the firmware to get a sinking out of a sourcing
[05:46:58] <rmu> don't think so. if that was possible the store would only list one variant.
[05:47:27] <PL7icnc> im off Bye

[06:02:08] <jthornton> morning
[06:04:23] <Wolf__> morning jt
[06:04:51] <XXCoder> hey
[06:06:32] <Wolf__> jthornton, I think I found a mistake on the instruction sheet that was with the 7i96, 10.10.10.1 ip address
[06:07:35] <jthornton> that looks like a typo to me
[06:08:53] <jthornton> the first line on that page is Ethernet Cards require LinuxCNC Uspace and the PREEMPT kernel.
[06:10:00] <Wolf__> yeah
[06:10:07] <jthornton> it can be 10.10.10.anything but 10
[06:10:16] <jthornton> the 7i96 is 10.10.10.10
[06:10:29] <jthornton> 1 should work
[06:10:30] <Wolf__> ahh
[06:11:23] <jthornton> and while I'm looking at that page I'll setup this PC lol
[06:11:31] <Wolf__> I think I’m going to need to rebuild my mint box lol
[06:11:36] <jthornton> did you use the configuration tool to build your configuration?
[06:11:59] <Wolf__> wont connect, I cant get hostmot2 to install/load
[06:13:04] <jthornton> did you install debian 9 uspace?
[06:13:34] <jthornton> I'm working on some new instructions for building uspace and kernels http://gnipsel.com
[06:14:12] <Wolf__> box I have set up right now is Mint 18 iirc
[06:15:15] <Wolf__> but I set it up over a year ago so used old directions w/ no clue what I was doing lol

[06:23:10] <jthornton> geez 52°F with a high of 65°F today in January that's nuts

[06:24:15] <Tom_L> 56F, Hi 59, Lo 37
[06:24:57] <Wolf__> does the mint desktop version make any difference?
[06:24:59] <Tom_L> had a speck of rain last night
[06:25:10] <Tom_L> Wolf_ITX_, no
[06:25:20] <Tom_L> user choice
[06:25:35] <Wolf__> I didn’t think it would =)
[06:29:34] <Wolf__> now, seeing that I know jack about linux, you can build the kernel on a different cpu then move it to the target machine right?
[06:39:41] <jthornton> I guess you can, but why?
[06:40:03] <Wolf__> 2 core atom vs 4 core i5
[06:42:52] <Wolf__> I know the intel atom builds really slow
[06:45:15] <jthornton> ah I see, give it a try and see
[06:51:06] <jthornton> just looking on this pc and I used address 10.10.10.11
[06:52:55] * jthornton installs linux mint 19.1 again to test the instructions

[15:13:27] <gloops> ive got big TV fatigue
[15:13:52] <gloops> no doubt the great masses will pursue the big TV ideal to the very end though
[15:14:14] <CaptHindsight> will they run out of money first?
[15:14:48] <gloops> they already have
[15:15:19] <CaptHindsight> not enough
[15:17:14] <gloops> Ford realised that if you want workers to be able to buy things you have to pay them more wages
[15:18:20] <CaptHindsight> that is history
[15:18:26] <gloops> we're still using that premise, but have now realised that its far more lucrative to give them credit, rather than up their pay
[15:32:20] -!- emsjessec has quit [Read error: Connection reset by peer]
[15:47:53] <elmo40> gloops, yeah. credit is the latest scheme
[15:53:41] <elmo40> stores do that instead of cash returns. they offer store credit.
[15:59:14] <CaptHindsight> banks want to give you credit so that you can get in trouble with it
[15:59:25] <CaptHindsight> they makes tons more money when you get behind
[15:59:38] <gloops> what they used to call usury
[16:00:10] <gloops> now promoted as 'easy payment plan'
[16:00:26] <mozmck> Renting money
[16:00:35] <mozmck> The rent isn't cheap
[16:05:59] <Jymmm> easy payment plan... for LIFE
[16:06:24] <fragalot> student loans.
[16:06:27] <fragalot> enough said
[16:06:50] <fragalot> first, you introduce the concept. then you get more people to join. then you more than quadruple the tuition fee
[16:19:41] <gloops> then you start making the as yet unborn children guarantors for the loan
[16:25:46] <gloops> anyone used very sharp angle V cutters on wood - like 10/20 degree angle?
[16:26:19] <SpeedEvil> The cutting speed gets very low at the bottom unfortunately
[16:26:31] -!- The_Ball has joined #linuxcnc
[16:26:35] <gloops> https://www.ebay.co.uk
[16:26:39] <gloops> that type
[16:26:53] <gloops> good point SpeedEvil
[16:27:20] <gloops> wondering how sturdy they are - or fragile
[16:27:38] <SpeedEvil> I wonder if those are in fact meant for enlarging holes.
[16:27:42] <The_Ball> pcb milling?
[16:28:14] <gloops> The_Ball i want to pick out some fine detail on wood carving, depth a couple of mm say
[16:29:00] <The_Ball> right, I use them for PCB milling and the finer the tip the better, but when it is that thin it takes nothing to break the tip and the cut become quite a bit wider
[16:29:32] <SpeedEvil> What sort of wood? You may need really fine finishes in order to not look bad. And variation over the grain direction is probably going to be big
[16:30:06] <gloops> what kind of depth of cut and feed for PCB?
[16:30:09] <SpeedEvil> Part of the thing about coarser tips is you can employ a more complex geometry.
[16:30:33] <SpeedEvil> So not to actually have that cutter speed=0 at the ti
[16:30:34] <SpeedEvil> p
[16:30:37] <gloops> SpeedEvil probably various woods
[16:31:04] <gloops> hmm, so actually a bigger tip to start is better for my purpose
[16:31:18] <SpeedEvil> I assume you can't do 5-axis things?
[16:31:39] <gloops> .3 mm be ok for me
[16:31:49] <gloops> nah just 3 axis
[16:32:07] <SpeedEvil> What's max spindle speed?
[16:32:32] <gloops> 24k
[16:33:01] <gloops> like the body hair detail on that https://www.fionakingdon.com
[16:33:01] <SpeedEvil> 300 revs per second, or 300mm/s cutter speed.
[16:33:13] <SpeedEvil> unless I'm confused
[16:33:36] <CaptHindsight> gloops: fetal credit, only surpassed by embryonic credit and later generational credit futures
[16:34:27] <The_Ball> been cleaning up the wiring on my old mill https://imgur.com
[16:34:34] <CaptHindsight> you can take out loans on the great great grand kids before they are even born
[16:34:39] <gloops> it works, but there will be a crash when immortality is discovered
[16:35:15] <CaptHindsight> nah, they will just pass laws on the poor not being able to go over 100
[16:35:31] <The_Ball> this is what it looked like when i bought it: https://imgur.com
[16:35:37] <CaptHindsight> have to pay to play
[16:36:44] <gloops> hope you didnt pull any wires out The_Ball lol
[16:37:46] <The_Ball> hehe, well I did but it wasn't working, now it is working and converted to LinuxCNC/Mesa
[16:38:03] <gloops> SpeedEvil i guess ill have to check out some PCB figures and watch some videos - these cutters are only pennies each anyway i may as well get some and play..until theyre gone
[16:38:18] <The_Ball> It has a DC spindle drive which was a pain to fix
[16:40:17] <SpeedEvil> gloops: not a wholly bad plan
[16:40:20] <gloops> is this for commercial use The_Ball, i mean is this your business or something?
[16:41:00] <The_Ball> No, just hobby
[16:43:12] <gloops> well theres hours of fun to be had with a mill like that heh
[16:53:03] <CaptHindsight> The_Ball: have a pic of the whole machine? (did i miss the link?)
[16:54:14] <CaptHindsight> i enjoy building them more than running them
[16:54:47] <CaptHindsight> designing really, even assembly can get boring
[16:56:23] <The_Ball> CaptHindsight, the front https://imgur.com
[16:57:34] <CaptHindsight> looks familiar, what was it?
[16:58:06] <The_Ball> It's an old swedish brand, "Modig" MD-5000

[17:15:30] * fragalot wishes ST would pull their head out of their ass & release libraries that ACTUALLY work
[17:15:39] <fragalot> so many example files for specific CPU's that are just plain wrong
[17:15:57] <renesis> like what?
[17:16:23] <fragalot> linker files saying the F303K8 has 16K of stack space whilst it's only really got 12
[17:16:27] <renesis> all the cubemx and std periph shit ive tried worked
[17:16:35] <fragalot> so the second you hit "run" it just hardfaults instantly
[17:16:50] <renesis> that sucks
[17:17:03] <fragalot> for the 722ZE the unique ID was wrong in the datasheet
[17:17:09] <renesis> what library are you using?
[17:17:20] <fragalot> for the 496ZG (iirc, could be a different one), ST-Link tools can not enable the OTP bits
[17:17:22] <Rab> The_Ball, nice machine. Looks like one of the drives is missing in the second pic, was it dead?
[17:17:23] <fragalot> etc
[17:17:46] <fragalot> renesis: bit of everything. Depends on what I need and which lib does it best.
[17:18:06] <fragalot> CMSIS, STM32Hal, ChibiOS HAL, ...
[17:18:18] <renesis> ah, i figure theyve given up on everything except the cubemx HAL stuff
[17:18:22] <fragalot> and Atollic as the debug env. because that just works.
[17:18:51] <renesis> yeah i went from keil to atollic, only thing i changed was byte alignment syntax
[17:18:52] <fragalot> i'm using cubeMX to generate my board config once & use python scripts to export it to the right format I need
[17:19:03] <renesis> haha hacker
[17:19:17] <fragalot> the UI makes it fairly nice, but the code it generates is annoyingly inconsistent :P
[17:19:56] <fragalot> and I like my hardware configuration to not change behind my back :D
[17:20:00] <renesis> i generate with cubemx and basically insert two or three functions and couple of includes into it, so easy to fix if it clobbers code
[17:20:06] <renesis> working well so far
[17:20:21] <fragalot> that's another way of doing it
[17:20:31] <renesis> can tweak in cubemx and update, and lately it hasnt had issues
[17:20:47] <fragalot> i'm using that python script so it generates code that ChibiOS likes
[17:21:12] <fragalot> well, I go from cubeMX --> intermediate config file for ChibiOS --> board.c & board.h file
[17:22:04] <fragalot> board.chcfg is what chibiOS uses as the format
[17:22:31] <renesis> havent played with any rtos on stm32 yet
[17:22:38] <The_Ball> Rab, the missing drive was for a forth axis, which I haven't got, so have removed it while debugging the spindle drive
[17:23:21] <renesis> nom, toolchanger

[17:38:21] <Jymmm> rene_dev_: Pfff, now THIS is a tool changer (aka cnc porn)... https://www.youtube.com
[17:38:29] <Jymmm> renesis: ^^^^^^^^^^^^^^
[17:45:03] <renesis> ha
[17:45:26] <Jymmm> renesis: More cnc porn https://www.youtube.com
[17:46:13] <renesis> the ones where they grab a tool from some carousel outside the machine are pretty nuts
[17:46:23] <renesis> changer bigger than the machine
[17:46:52] <Jymmm> heh
[17:47:23] <Jymmm> haha, I just read the first comment on that last video
[17:48:21] <Jymmm> the live handoff is orgasmic =)
[18:00:37] <gloops> hmm, they are ok, you really need the tool rack under the work surface though, with a metal iris to open when the tool needs changing
[18:05:35] -!- syyl has quit [Quit: Leaving]
[18:09:14] <The_Ball> lol, that IS a toolchanger, but I'm very very happy to have my first toolchanger even if it only 15 pockets
[18:13:44] <SpeedEvil> gloops: With a rotating ring around the iris and blue LASER illuminating a fine coolant mist?
[18:21:43] <Jymmm> Not bad at all actually... https://www.youtube.com

[19:30:28] <Wolf__> jthornton: around? ran “./configure --enable-build-documentation” and get a “configure: error: intltool-extract not found”
[19:38:41] <ziper> how much is this worth
[19:38:42] <ziper> https://www.bidspotter.com
[19:38:51] <ziper> I thought you could dress a wheel with just a little hand tool
[19:39:29] <Wolf__> for surface grinder
[19:39:43] <Wolf__> to do angles/radius dress
[19:41:49] <ziper> oh
[19:41:50] <ziper> neat
[19:44:34] <Wolf__> checking to see what I paid for mine
[19:45:08] <Wolf__> https://i.imgur.com $105 for the lot

[19:53:58] <ziper> anybody used an optical comparator?
[19:59:33] <Jymmm> not i a bazillion years
[20:00:40] <ziper> what made them obsolete?
[20:01:13] <Jymmm> Not digital enough? lol, I don't have a clue =)
[20:02:37] <andypugh> CaptHindsight: I don’t know. Something off the shelf. Ford seem to be watching the market at the moment, seeing which way it goes. Try buying an electric Ford...
[20:05:20] <ziper> this IS a horizontal machine, right? https://www.bidspotter.com
[20:05:31] <andypugh> If you can find one, the pantograph dressers can make impossibe jobs easy. Search this page for “Diaform” http://www.lathes.co.uk
[20:06:23] <andypugh> ziper: Cute mill. Do you need a museum piece :-)
[20:06:46] <ziper> whats wrong with it?
[20:06:46] <CaptHindsight> https://www.ford.com
[20:07:04] <andypugh> It’s lovely, if you want a collection of old machine tools.
[20:07:10] <CaptHindsight> US anyway
[20:07:39] <andypugh> CaptHindsight: Aye, but low-mix hybrids
[20:08:02] <ziper> i'm not getting a 20k cnc anytime soon
[20:08:11] <andypugh> (not that the others are much better, my sister has a hybrid Golf with 4 miles electric range at < 30mph
[20:08:26] <ziper> but if I need a specific gear, it would be nice to have
[20:09:12] <andypugh> I have a horzontal mill myself, but it has a vertical head, and is from the 60s not the 30s.
[20:09:43] <ziper> would a nichols be better?
[20:10:42] <andypugh> https://www.youtube.com A reare example of CNC horizontal milling (my machine)
[20:11:52] <ziper> I was impressed at just using a mechanically linked indexing head to make helical gears
[20:12:37] <andypugh> Mechanically linked is just so 20th Century :-)
[20:13:32] <andypugh> My Harrison is great for making custom gears, or custom timing belt pulleys

[20:15:12] <andypugh> I am not saying “don’t get a horizontal” I am saying “get one with a verical head and a lot of metal in the over-arm.
[20:15:14] <ziper> would such a custom profiled surface grinding wheel have an accuracy advantage over a CNC milled part?
[20:15:47] <andypugh> Definitely a finish advantage, and it could be made to size from pre-hardened steel.
[20:16:08] <ziper> what do you mean by vertical head?
[20:16:16] <norias> oh, surface grinding. :)
[20:16:36] <andypugh> ziper: It’s like a head, but vertical :-)
[20:16:49] <ziper> so isn't that just a vertical mill?
[20:16:49] -!- micges has quit [Ping timeout: 250 seconds]
[20:17:56] <andypugh> https://www.youtube.com and look at the 15 seconds mark. That is the vertical spindle dangling from the crane.
[20:18:42] <andypugh> And here it is mounted showing off the pneumatic drawbar I made.
[20:18:43] <andypugh> https://www.youtube.com
[20:21:04] <ziper> well there is two bridgeports and a clausing lathe too
[20:21:13] <ziper> i'll be going for whatevers a good deal
[20:22:24] <ziper> that drawbar is rather erotic
[20:26:03] <andypugh> The Clausing lathe looks OK, and new enough to have decent spindle speeds.
[20:26:26] <andypugh> (Though it wouldn’t hurt to do some research)
[20:26:58] <andypugh> You don’t have to go back too far in time to find good 12” lathes with a 400rpm top speed.
[20:27:19] <andypugh> (which is rather slow for modern tools and materials)
