[00:46:02] <hazzy-m> Interesting, I noticed something similar, but thought it was my screws. Does it only happen during keyboard jogs?

[02:44:27] <ItsFlipp_> YESS! Finalllly figured out my heat problem
[02:44:41] <ItsFlipp_> turns out my old coolant was just ... awful
[02:44:53] <ItsFlipp_> Polymer only, not cut with water
[02:45:12] <ItsFlipp_> switched to KoolMist 77 (1:32 with water), and presto, no more heat at all

[05:21:14] <gloops> .
[05:21:15] <XXCoder> that looks like SAME machine
[05:21:23] <XXCoder> same pics even
[05:22:05] <gloops> he might have bid on that before - the one he was bidding on last time was a piranha

[05:22:29] <gloops> dont think he would have got that for his 5k limit
[05:22:45] <XXCoder> well one you linked is well below that lol
[05:23:12] <gloops> for now - probably go up a lot
[05:23:18] <XXCoder> yeah
[05:23:39] <gloops> something funny when hes selling on a 0 feedback a/c
[05:25:56] <jthornton> morning

[05:29:00] <jthornton> what's up this morning
[05:29:16] <XXCoder> just got home from work
[05:29:28] <XXCoder> so techinically its still thursday for me lol
[05:29:41] <gloops> nothing much, just loaded an engine up for the scrapyard, going to throw on whatever other scrap metal ive got laid about
[05:29:43] <jthornton> just waiting for the coffee pot to fire up
[05:30:06] <jthornton> I need to make a trip to the scrap yard and clean out my shop lol
[05:31:27] <gloops> ive been going to move this engine for 5 years lol
[05:33:32] <jthornton> I know that feeling about putting stuff off till years later, I had planned on painting the house last summer...

[06:24:24] <XXCoder> morning
[06:26:25] <CNC_Brian> Morning all
[06:27:13] <CNC_Brian> Anyone know what the latency test executable is called?
[06:27:26] <CNC_Brian> Cant see it in bin
[06:27:51] <XXCoder> should be in linuxcnc menu but dunno name
[06:27:55] <jthornton> there are two of them latency-histogram and latency-test
[06:28:37] <jthornton> latency-histogram --help
[06:28:42] <jthornton> for options on that one
[06:28:47] <CNC_Brian> What folder do they live in JT?
[06:29:11] <jthornton> I'd guess /usr/local/bin maybe why
[06:29:25] <CNC_Brian> I have a rip install
[06:29:45] <jthornton> from the rip top level directory do this
[06:29:54] <jthornton> . ./scrips/rip-environment
[06:30:05] <jthornton> then run the latency test of your choice
[06:30:18] <CNC_Brian> Cool got it. Thanks.
[06:30:21] <jthornton> in a terminal of course

[07:05:23] <Loetmichel> *GNIHI*... man, i love this company sometimes... customer: "can you send us a demo tft monitor so we can see the build quality and optical properties of the shielding glass?" Boss: "sure!"... proceeds to send one with a big crack in said glass ;)
[07:05:55] <XXCoder> lol
[07:23:43] -!- emsjessec has joined #linuxcnc
[07:35:03] <CNC_Brian> JT, your Stepgen spreadsheet and wiki article , Im confused.
[07:35:31] <CNC_Brian> So the Max jitter on the base thread on this old pc is 25000nS
[07:35:46] -!- gloops has quit [Ping timeout: 244 seconds]
[07:43:39] <CNC_Brian> Is max Jitter == worst case latency?
[07:44:47] <XXCoder> techinically you could run on really bad jitter
[07:44:54] <XXCoder> but it can cause problems
[07:45:12] <XXCoder> causing you to have to set quite low stepgen speed
[07:45:35] <CNC_Brian> Is 60,000nS Jitter on the Base Thread bad?
[07:46:02] <CNC_Brian> Seems high
[07:46:06] <jthornton> for a mesa card you don't use base thread
[07:46:14] <XXCoder> forgot what range is lol so dunno. but compared to my 14 year old pcs 15k yeah higher
[07:46:30] <CNC_Brian> No this is a different setup on an lathe
[07:46:36] <XXCoder> disable power saving systems any of em
[07:46:38] <jthornton> which spreadsheet and article are you talking about?
[07:47:18] <CNC_Brian> Im going through this : http://wiki.linuxcnc.org
[07:47:20] <jthornton> you can run the stepconf tool and see what the max step rate is for that latency
[07:47:48] <jthornton> that is very very very old
[07:48:16] <jthornton> last edit 7 years ago
[07:48:30] <XXCoder> CNC_Brian: be sure that your power savings configuration for that pc is all off.
[07:48:49] <CNC_Brian> Will do
[07:49:05] <XXCoder> dammit I meant power management
[07:49:14] <XXCoder> like hdd off, screen off, cpu controls etc
[07:49:51] <CNC_Brian> So using step config I have steplen =1 and stepspace = 0
[07:50:00] <CNC_Brian> Dirhold 44000
[07:50:28] <SpeedEvil> https://youtu.be - how to improperly knurl a knob.
[07:50:56] <CNC_Brian> Base period is 100000
[07:51:34] <XXCoder> lo SpeedEvil thats not even close to wat jurling is
[07:51:55] <SpeedEvil> Indeed.
[07:52:34] <XXCoder> end result is sucky "kurling"
[07:53:06] <XXCoder> ... he cut it to size after doing that. might be bad idea if it ends up wrong size
[07:53:35] <XXCoder> that tool is interesting
[07:53:52] <SpeedEvil> Router planes are fun.
[07:54:37] <jthornton> hitting a file with a hammer what an idiot
[07:54:54] <XXCoder> granted he said only use old and basically dead file
[07:55:08] <SpeedEvil> if you don't care about the file, and are wearing face protection - meh.
[07:55:24] <SpeedEvil> Easy way to lose an eye though.
[07:55:29] <XXCoder> yeah you dont want to be blind or new Scarface
[07:56:17] <XXCoder> its likely boring just standing behind and little bit to left from your mob boss.
[07:56:36] <XXCoder> and you need to exercise to get to mob thug strength and look
[07:56:50] <XXCoder> boring. so dont risk your eye and face ;)
[08:02:06] <Jymmm> jthornton: FWIW... https://www.amazon.com
[08:05:35] <Jymmm> jthornton: I'm just taking it apart to connect to air hose =)
[08:27:52] <Jymmm> You think hitting a file is bad? This looks and sounds a tad scarry... https://www.youtube.com
[08:27:58] <Tom_L> i bet that guy's an awesome machinist too
[08:28:25] <XXCoder> Jymmm: so fancy intro
[08:29:32] <Jymmm> XXCoder: You hear him yelling out instructions to the guys at the end of the rod
[08:29:40] <XXCoder> hear?
[08:29:48] <Tom_L> at least the applied the ky first
[08:29:59] <XXCoder> heh I can SEE him yelling yes
[08:30:05] <Jymmm> XXCoder: I know you can't, but I'm saying that's what he's doing... left, right, etc
[08:30:16] <XXCoder> lol ok :)
[08:30:48] <XXCoder> didnt expect him to put on goggles
[08:30:57] <Jymmm> XXCoder: Then the machine starts to creak a bit, then his yelling gets intense =)
[08:31:22] <Tom_L> those are his kid's glasses
[08:31:31] <Jymmm> If that machine fubared, safety google aint gonna help
[08:31:35] <XXCoder> other guyb dont use it
[08:31:48] <Jymmm> It's solid rod, not tube either
[08:31:50] <XXCoder> indeed it wouldnt do crap as rod goes though head
[08:33:12] <XXCoder> wow hes talking so fast
[08:33:58] <Jymmm> Hey, no big deal, let me just carry around this hot metal like it's nothing https://www.youtube.com
[08:38:00] <XXCoder> roller parts is interesting
[08:38:01] <XXCoder> so big
[08:39:54] <Jymmm> the 75 ton 30ft ring you mean?
[08:40:58] <XXCoder> yea
[08:49:50] <CNC_Brian> Well that was interesting. Took a 2.7 software Stepgen config and upgraded the PC to 2.8 and it ran like a dog.
[08:50:23] <CNC_Brian> Base thread was 100000 default stepconfig value
[08:50:51] <CNC_Brian> Stepper where missing steps, machine sounded horrible.
[08:51:32] <CNC_Brian> Though maybe the steps where too fast so slowed the base thread down to 200000
[08:51:37] <CNC_Brian> Even worse
[08:52:00] <CNC_Brian> Cranked the base threat unto 30,000 and runs like a dream
[08:52:45] <CNC_Brian> Im obviously not understanding the fundamentals here?

[09:24:31] <miss0r> Anyone in here got a good recipe for chipbreaking 42crmo4 on a lathe?

[09:25:23] -!- Inline has quit [Read error: Connection reset by peer]
[09:25:27] <PL7icnc> miss0r, did you Consider chipbreaking bits
[09:25:49] <miss0r> chip break bits? :S
[09:25:58] -!- Inline has joined #linuxcnc
[09:26:12] <miss0r> as in; inserts with build in chip break? (if so, i've tried a few different ones now, with no success)
[09:27:02] <gregcnc> what are cutting parameters?
[09:27:34] <PL7icnc> miss0r, yes
[09:27:42] <miss0r> what I am currently running, gregcnc?
[09:27:44] <gregcnc> never had trouble with that material
[09:27:48] <miss0r> realy?
[09:27:52] <miss0r> what inserts are you using?
[09:27:56] <gregcnc> whatever
[09:28:05] <miss0r> ha...
[09:28:13] <PL7icnc> miss0r, https://www.youtube.com
[09:28:15] <miss0r> I get a birdsnest nomatter what I do, it seems
[09:29:36] <miss0r> PL7icnc: I would get tired in a hurry, if I had to use toolbit steel for the cutting here : ]
[09:30:48] <miss0r> Interrestingly I can find quite a few externally mounted chip breakers to mount on top of the insert holder to break up the long string that comes off 42crmo4
[09:31:02] <miss0r> But noone mentions any good inserts, that will do it for me
[09:31:21] <gregcnc> so what are cutting parameters?
[09:31:24] <miss0r> Problem is, the way I understand it; the material is too tough(elastic) for this to work proberly.
[09:31:27] <miss0r> ahh, hang on
[09:33:15] <miss0r> I've tried; 560-1220 rpm. This is a 38mm blank.
[09:33:46] <miss0r> I've tried feeding it in at anything between 0.054mm/rev to 0.2mm/rev
[09:34:03] <miss0r> and everything between 0.1-3mm doc
[09:34:11] <miss0r> on a large vareity of different inserts
[09:34:26] <rmu> sounds like an awful lot of permutations you tried there
[09:34:57] <miss0r> rmu: Honnestly I was not 100% scientific about it :D and I aborted a setup if it sounded off
[09:35:14] <miss0r> so, alot of different combinations of the above mentioned parameters have been tried
[09:35:26] <miss0r> and I have not so far been able to break the chip
[09:35:33] <gregcnc> I would go faster
[09:35:49] <SpeedEvil> That's only what - 2m/s?
[09:35:49] <miss0r> my max on this lathe is 1550rpm.
[09:35:55] <SpeedEvil> ah
[09:36:16] <rmu> get a bigger blank then ;)
[09:36:25] <gregcnc> yes ask the customer for a larger part
[09:36:28] <miss0r> :)
[09:36:30] <miss0r> hehe
[09:36:36] <miss0r> well. this is one of my own doing
[09:36:50] <miss0r> but I am planning to make 10 of these shafts to start with.
[09:37:04] <miss0r> (a land rover spare part, that is impossible to get in a proper quality)
[09:37:13] <SpeedEvil> just put a spinning thing next to the insert and reel it up
[09:37:32] <miss0r> SpeedEvil: To tell you the truth, I did comtemplate on that :)
[09:37:35] <gregcnc> my lathes are small so i use mostly Sandvik positive inserts
[09:38:22] <miss0r> I've gone through the range of inserts. but I quickly aborted on the negative rake ones.. :) the shaft is too long and thin + supported by a center in the end
[09:38:24] <gregcnc> dcmt070204-um 1125
[09:39:34] <rmu> you could pre-mill a groove
[09:39:39] <miss0r> I have some of quite simular geometry - they did not do the trick
[09:39:52] <miss0r> rmu: hehe, I could. but that would reak havok on my inserts :D
[09:40:12] <gregcnc> recommended VC is 135-225m/min and they do indeed like 150+
[09:40:17] <SpeedEvil> miss0r: Also - what's wrong with a chip-breaker stuc on top?
[09:40:28] <rmu> just make the chip thinner, without interruption, the inserts should be fine then
[09:40:28] <miss0r> SpeedEvil: I don't have one :D
[09:40:45] <SpeedEvil> miss0r: Seems shop-makable pretty easily
[09:41:19] <miss0r> SpeedEvil: hehe yeah, start a project; make a new tool for project - spend so much time on new tool you forgot the original project that started it all
[09:41:28] <SpeedEvil> :)
[09:41:53] <SpeedEvil> yeah - but a chip-breaker is a few minutes with dremel+ grinding wheel surely - faster than trying many feeds/speeds
[09:42:07] <miss0r> I'll make a few attempts at some chip breaking equipment. But I think I'll just send a 20x quantity or something like that to a friend of mine with a cnc lathe, and let him worry about it :D
[09:42:21] <rmu> get a landrover, instead of driving in the mud you will end up rebuilding everything (including tooling) from scratch
[09:42:38] <miss0r> rmu: yes, ain't it beautiful? :)
[09:43:09] <miss0r> the beauty of an old land rover(mines 47 years old) is that it can take even the simplest short drive and turn it into an adventure
[09:43:14] <miss0r> this is why you gotta love it :)
[09:43:26] -!- PL7icnc has quit [Quit: Leaving]
[09:43:31] <rmu> reminds me of my dislike of closed systems. then you end up building your own CNC controls...
[09:43:53] <miss0r> I actualy have a new controller to add to my cnc mill at some point
[09:43:57] <SpeedEvil> rmu: I note open-source ECUs exist.
[09:44:09] <miss0r> completely wired up ect. I just haven't gotten around to programming it yet
[09:44:20] <SpeedEvil> rmu: I suspect you could do ECU on linuxcnc
[09:44:24] <SpeedEvil> (if you were insane)
[09:45:10] <rmu> ECU on linuxcnc? why? don't understand. ECU would be something for mikrocontroller
[09:45:25] <SpeedEvil> Indeed.
[09:45:32] <rmu> and I probably wouldn't trust my own ECU software
[09:45:58] <SpeedEvil> It was an aside - opensource ECU is already available, no need to roll your own from scratch
[09:46:14] <rmu> I had my "sudden, unexpected and not commanded acceleration" moments with my programs if you know what i mean
[09:46:31] <miss0r> rmu: This is what my new controller looks like: https://imgur.com
[09:46:57] <rmu> nice and tidy
[09:46:59] -!- P1ersson has quit [Ping timeout: 255 seconds]
[09:47:18] <miss0r> and realy complicated. the PCBs in the middle are translators, so I can use the original linear scales
[09:47:58] <miss0r> anyway. I best get going. I have to go pick up the kids. See you around
[09:48:05] <SpeedEvil> wave
[09:48:07] <rmu> i will bid on a second biesse rover 342, 25 year old CNC monster, for spare parts.

[12:05:02] <CNC_Brian> II first noticed it when I homed the Z axis
[12:05:32] <CNC_Brian> ]Its quite bad, I though I had a seizer ball screw.
[12:08:06] <hazzy-m> yeah, I thought it was in the screw too, I cleaned them but it didn't help, then saw your comment and realized it might be in the software

[12:24:28] <SpeedEvil> A 1-legged stool would be cool.
[12:24:44] <SpeedEvil> Couple of axes connected to the leg on the seat, so it balances.

[14:10:27] <fragalot> syyl: you mean you don't like the all out american style?
[14:10:56] <syyl> we have to machine faster or they will steal our jobs!
[14:11:34] <fragalot> I mean.... he's not entirely wrong
[14:11:35] <gregcnc> i've watched maybe two of his videos
[14:11:57] <fragalot> if you can do the same job with the same end result in less time than your competitor can..
[14:12:17] <gregcnc> and still make money.....
[14:12:35] <fragalot> that part is optional if you can push the other guy out of business first
[14:13:13] <gregcnc> bank still wants payment on the machines
[14:13:56] -!- ve7it has joined #linuxcnc
[14:14:05] <fragalot> it worked for amazon
[14:14:06] <fragalot> :D
[14:14:24] <gregcnc> walmart did it too
[14:16:30] <gregcnc> syyl do you make many trepan tools?
[14:16:43] <syyl> for the lathe?
[14:16:51] <syyl> rarely
[14:16:51] -!- PL7icnc has quit [Quit: Leaving]
[14:17:03] <gregcnc> this will actually be a milling op
[14:17:54] <fragalot> same difference, no? :P
[14:18:16] <gregcnc> yes/no
[14:20:46] <gregcnc> It doesn't look like most tools have much side clearance
[14:22:12] <gregcnc> other than feeding slower is one edge a problem?
[14:22:55] <syyl> you want to run a trepaning tool in a boring head?
[14:23:12] <syyl> they cant have much clearance, otherwise they get very skiny
[14:23:14] <gregcnc> radial live tool in the lathe
[14:23:24] <syyl> ah ok
[14:26:02] <gregcnc> small feature Ø2.5, 2-3mm tall this looks good, but hss http://www.tristareng.com
[14:27:36] <syyl> lots of parts?
[14:28:04] <gregcnc> aluminum, maybe 100
[14:28:54] <syyl> i would be tempted to just mill it
[14:28:59] <syyl> for such a small feature
[14:30:04] <gregcnc> I should see how mishapen it gets with a regular endmill
[14:31:37] <gregcnc> just want to avoid a separate operation. my design so I get to play with it
[14:32:24] <syyl> livetool has only collet chuck, right?
[14:32:31] <gregcnc> yes
[14:32:53] <syyl> if i felt like beeing experimental, I would draw/design a solid carbide tool in cad
[14:32:58] <syyl> and grind it that way
[14:33:37] <gregcnc> https://muskegontool.com
[14:34:31] <gregcnc> this is obviously large, but a single cutting edge cut from solid
[14:34:32] <syyl> can you see that picture in the link?
[14:34:33] <syyl> https://www.instagram.com
[14:34:45] <gregcnc> yes, just liek that
[14:34:46] <syyl> thats what i would grind, just smaller ;)
[14:35:08] <syyl> and so it cuts on size without need adjusting by a boring head
[14:36:40] <gregcnc> yes, that's what I'm after. shank is concentric to the feature produced
[14:37:51] <gregcnc> probably even have a splint blank in the box
[14:38:10] <gregcnc> Thanks!
[14:38:16] <syyl> no problem :D
[14:38:21] <syyl> not sure if i was of any help ;)
[14:38:48] <gregcnc> I started with a far too complicated idea, this is better
[14:38:55] <syyl> :)
[14:39:14] <gregcnc> I probably even saw that on insta, but forgot
[14:52:00] <FinboySlick> gregcnc: If you didn't need a specific width, I'd have suggested a hole saw or annular cutter but at those sizes it's not very realistic.
[15:02:25] <gregcnc> yes, those are ok for coring stock
[15:09:34] <fragalot> does anyone know if there is an equivalent to pallet changers for lathes?
[15:09:56] <gregcnc> part loaders?
[15:11:08] -!- gloops has joined #linuxcnc
[15:12:15] <fragalot> part loaders, and a way to swap jaws for different size parts
[15:12:51] <fragalot> starting with hard 3-jaws set at ~40mm, sub-spindle with soft jaws for 38mm
[15:13:05] <fragalot> switching to 10mm and 8mm soft
[15:13:15] <fragalot> (or collet)
[15:13:22] <gregcnc> chucks are not automated like that
[15:13:28] <fragalot> indeed they are not
[15:13:30] <fragalot> hence me asking :D
[15:13:48] <gregcnc> what are you asking then?
[15:14:45] <methods_> http://www.positrol.com
[15:14:58] <methods_> i think they make quick changeover chucks for automated changeovers
[15:15:29] <fragalot> I know that schunk makes chucks that have jaws that can be actuated with a robot arm to adjust them
[15:15:43] <fragalot> just figured i'd ask if there were alternative techniques that I hadn't thought of, or didn't know about
[15:15:44] <methods_> https://www.mmsonline.com
[15:16:43] <fragalot> thanks methods_, looks interesting
[15:16:45] <gregcnc> wow who uses that stuff?
[15:16:59] <methods_> someone running lights out
[15:17:04] <fragalot> gregcnc: ^
[15:19:53] <gregcnc> OK I just imagine if volume is high enough to run lights out, how often do you need to change fixturing?
[15:20:53] <fragalot> low volume high mix
[15:20:54] <methods_> ah yeah i guess if you're trying to be "agile" or whatever the new buzz word is
[15:21:05] <methods_> yeah
[15:21:46] <gregcnc> but jobs would have to repeat to make sense?
[15:21:57] <methods_> i would think so
[15:21:59] <fragalot> can't go into details on numbers, but it makes sense to reduce dedicated machines & set up fewer, more flexible machines that don't take 4hrs of setup time
[15:22:04] <fragalot> gregcnc: yes
[15:22:11] <methods_> i've never had much luck running a job i've never run before lights out lol
[15:22:24] <gregcnc> so one shift sets up, and the machine runs three
[15:22:45] <fragalot> why run the machine for 3 shifts to produce 4000 parts of something if you only need 100?
[15:23:14] <fragalot> if you can reduce the setup time of the machine (again, this is for 100% repeat parts) to minutes
[15:23:23] <fragalot> just run the 100 parts & move on to the next one
[15:23:49] <gregcnc> what about tools?
[15:24:02] <fragalot> that's another conundrum i'm looking into
[15:24:18] <fragalot> currently the lathe makes most sense for the type of parts, but the options you get in terms of lights out operation on 5axis VMC's is beyond compare
[15:24:37] <fragalot> pallet changers, huge tool banks, all exists "off the shelf"
[15:24:46] <methods_> i mean all that sandvik capto stuff is made for automated tool changeovers
[15:26:07] <fragalot> methods_: good point, those could be automated too, external to the machine, I guess
[15:27:04] <methods_> https://www.youtube.com
[15:29:22] <methods_> https://www.youtube.com
[15:29:27] <methods_> better video of okuma setup
[15:29:33] <methods_> with tool changes on turret with capto
[15:31:24] <fragalot> i've been looking at that collet system from schunk
[15:32:12] <fragalot> nearly exactly what I was looking for :D
[15:32:39] <gregcnc> how much money in that okuma clip?
[15:32:39] <methods_> yeah that snap in collet system
[15:32:48] <methods_> for that cell?
[15:32:52] <gregcnc> yes
[15:32:56] <methods_> sheesh probably 1.5million
[15:33:00] <methods_> maybe more
[15:33:28] <methods_> i dont' know i've never had the chance to get something like that quoted
[15:33:31] <methods_> lol
[15:33:50] <methods_> probably more like 3-4 million
[15:44:26] <methods_> heh mazak just changes the chuck jaws
[15:44:28] <methods_> https://www.youtube.com
[15:44:30] <methods_> at 2:15
[15:45:26] <fragalot> those mazaks are purdy little things aren't they
[15:45:47] <methods_> i'm kinda partial to okuma myself
[15:46:21] <fragalot> i've got no preference as long as it's beefy & fast
[15:47:46] <methods_> yeah i'm always stuck on whatever so i really don't care either
[15:47:52] <methods_> but those okumas are reallllllyyy nice
[15:48:04] <methods_> the mazaks aren't too bad either
[15:48:21] <methods_> except for all that mazatrol silliness
[15:49:26] <fragalot> the controls we're going to go for is probably going to be something from siemens
[15:49:44] <fragalot> just to keep everything talking to eachother without having to jump through weird hurdles
[15:50:12] <methods_> ah well i guess that kinda limits you
[15:51:14] <fragalot> a little
[15:51:30] <methods_> i don't even know who uses siemens controllers besides dmg
[15:51:48] <methods_> but now that they're dmg/mori i don't know what they use
[15:52:11] <methods_> mori was mainly fanuc
[15:52:15] <fragalot> they still supply siemens
[15:52:23] <fragalot> if you ask for it

[19:11:00] <ItsFlipp_> (can't remember who else was helping me diagnose)
[19:11:03] <ItsFlipp_> but thanks all
[19:11:25] <ItsFlipp_> turns out it was my crappy coolant I was using. it was a "premix", but they said to use it neat (without cutting it with water)
[19:11:39] <ItsFlipp_> and thus all it did was burn/heat up and didn't actually cool at all
[19:11:56] <ItsFlipp_> switched to a 32:1 dilution of KoolMist 77 and bingo, no more heat at all
[19:12:40] <jthornton> glad you got it sorted out
[19:12:49] <ItsFlipp_> ah, yeah, thanks for the help :)
[19:13:40] <ItsFlipp_> turns out I had a slightly different problem in that the masking tape failed to hold onto the part due to the new water-based coolant, but that one's solvable
[19:13:52] <ItsFlipp_> finally finished the part last night in the vise

[20:47:20] <cncnoob> Hey, can anyone tell me why I would want a finishing spindle? I read the description, but I don't get the point. Does it prevent you from having to remount the work piece? Why can't you just use the normal spindle?
[20:47:26] <cncnoob> https://www.haascnc.com
[20:49:01] <XXCoder> it transfers from main spindle so you can finish other side of part without losing position
[20:49:16] <XXCoder> can be very effective
[20:49:52] <cncnoob> So the work piece is moved from the main spindle to the finishing spindle automatically?
[20:49:59] <XXCoder> fancy machine can move finishing spindle in and grip part, then bpth main spindle and finishing spindle spin as its cut off rod
[20:50:12] <XXCoder> that one dunno but swiss lathe I saw does.
[20:50:28] <XXCoder> looks like yes
[20:50:37] <XXCoder> imply load up your raw workpiece, and the next time you open the door, you’ll have a finished part. Note: Requires VB hybrid turret; not compatible with the tailstock option.
[20:50:49] <cncnoob> It is an $18K option on a Haas ST-10
[20:51:08] <gregcnc> yeah not cheap
[20:51:10] <XXCoder> if you make thousands of parts thats worth all the 18k.
[20:51:26] <gregcnc> productivity can be tremendous
[20:51:37] <cncnoob> I guess it is only of benefit on 2 op parts right?
[20:51:44] <XXCoder> swiss lathe at work already made tens of thousands
[20:51:50] <gregcnc> which parts aren't 2 op?
[20:51:54] <XXCoder> is there such thing as one op part?
[20:52:17] <cncnoob> I've never run a lathe, but I would think so?
[20:52:31] <XXCoder> swiss lathe will take a bit to cover itself in profit tho lol its one million bucks usd
[20:52:40] <gregcnc> many parts can be made by simply parting off
[20:52:45] <XXCoder> if you dont care about one side finish sure
[20:52:58] <gregcnc> 1M$ swiss?
[20:53:05] <XXCoder> swiss lathe yeah
[20:53:09] <gregcnc> which
[20:53:20] <XXCoder> dunno didnt look at model #
[20:54:16] <XXCoder> whats interesting is that it uses swiss oil.
[20:54:18] <XXCoder> no coolant
[20:54:24] <gregcnc> they all do
[20:54:44] <gregcnc> what's interesting is that some use the same oil for the ways
[20:54:45] <XXCoder> we have one barrel and one chip bin thats reserved for it. oil must be pricy!
[20:55:19] <gregcnc> yeah
[20:55:33] <gregcnc> kilobuck a drum
[20:55:53] <cncnoob> I've been trying to start a business for a couple of years now and I'm finally looking to purchase a "real" machine. Something that can make a lot of small round things without me holding its hand
[20:56:03] <XXCoder> interesting. what they do is leave chips in bin for while so oil drains down
[20:56:08] <cncnoob> I'm comfortable with LinuxCNC, but have only used it on mills
[20:56:20] <cncnoob> any suggestions on a lathe to run LinuxCNC on?
[20:56:39] <XXCoder> you want machine that is completely insurable and warrantable if its pretty expensive one
[20:57:27] <cncnoob> If I can't find a suitable machine that I can use LinuxCNC with, I will likely get something like this:
[20:57:28] <cncnoob> https://www.haascnc.com
[20:58:01] <gregcnc> that's an expensive machine for it's capacity
[20:58:05] <cncnoob> It is fairly limited, but it is also small and inexpensive compared to many other options
[20:58:13] <cncnoob> I'm open to better options
[20:58:18] <XXCoder> i dont really like haas
[20:58:27] <XXCoder> none of machines I ran really impressed me
[20:58:34] <cncnoob> What don't you like?
[20:58:42] <XXCoder> hard to say really
[20:58:45] <XXCoder> just feel ehh
[20:58:46] <cncnoob> I have never used a Haas machien
[20:58:51] <XXCoder> not as bad as hurco LOL
[20:58:54] <cncnoob> but I like the fact that they have a lot of learning material on line
[20:58:58] <gregcnc> if you want new go for it, but there is a lot on the used market
[20:59:00] <XXCoder> I rather run old fadal 88 than hurco
[20:59:04] <cncnoob> and there is a factory outlet 10 minutes from me
[21:00:00] <XXCoder> if someone asked me to work hurco or quit.. I would... work at hurco but maybe seek other jobs lol
[21:00:17] <XXCoder> hint: DONT BUY HURCO lol
[21:00:37] <cncnoob> noted :)
[21:01:01] <gregcnc> big jump from dead machine to put linuxcnc on to new haas
[21:01:15] <gregcnc> just buy a used machine that runs
[21:01:20] <gregcnc> or needs some work
[21:01:43] <cncnoob> dead machine?
[21:01:53] <gregcnc> I assume dead if you want to retrofit?
[21:01:57] <cncnoob> My machine runs, but I don't have a lathe
[21:02:18] <gregcnc> you asked about a lathe for linuxcnc
[21:02:19] <cncnoob> I have a mini mill that I converted with a 4th axis to do proto typing
[21:03:00] <cncnoob> Yeah, just because I'm familiar with LinuxCNC. It would be nice if there was some new stuff out there that used LinuxCNC as its controller
[21:03:20] <XXCoder> yeah'
[21:03:27] <cncnoob> I have a project, I don't want another project, that is why I'm looking to buy new
[21:03:29] <gregcnc> I started a lathe linuxcnc retrofit, but bought a lathe before it was done
[21:04:04] <gregcnc> to be honest i don't know how people can stand programming a lathe in linuxcnc but there are plenty of examples on YT
[21:04:48] <Tom_L> i did a cad cam part for a lcnc lathe but most of the time we just MDI the parts
[21:05:40] <cncnoob> Another reason I was looking at that Haas lathe is because it could do tiny stuff
[21:05:55] <gregcnc> my lathe is about that size
[21:05:58] <cncnoob> the largest thing I would make would be 1" diameter
[21:06:07] <cncnoob> Most would be 1/4"
[21:06:15] <cncnoob> Those would be gears
[21:06:35] <gregcnc> it won't cut gears?
[21:06:50] <cncnoob> Why not?
[21:07:23] <gregcnc> you need a hobber
[21:07:51] <cncnoob> Can't you use those discs?
[21:08:05] <cncnoob> I've seen like an 8 pack of discs that cut gears
[21:08:28] <cncnoob> something like this
[21:08:28] <cncnoob> https://www.amazon.com
[21:08:57] <gregcnc> in the CL-1??
[21:09:17] <cncnoob> Yeah. Why not?
[21:09:26] <XXCoder> for number of teeth and angles nice
[21:10:05] <XXCoder> cncnoob: btw one of reasons I hate hurco, if I pause it would suddenly take spindle to z zero
[21:10:18] <XXCoder> if its cutting though something on side.. well too bad.
[21:10:19] <gregcnc> you'll want to look into it a bit more, that just isn't possible on most 3 axis lathes
[21:10:51] <gregcnc> I wish I could make gears on mine, but I can't
[21:10:53] <cncnoob> There is a C axis option
[21:10:55] <cncnoob> and with live tooling
[21:11:00] <cncnoob> I thought it should be possible
[21:11:03] <gregcnc> no
[21:13:53] <gregcnc> If you built a special live tool, you could, assuming there is space in that machine
[21:16:32] <cncnoob> I would really like to find a solution where I can cut gears and other small round parts on one machine
[21:16:50] <gregcnc> that's a big ask
[21:17:06] <cncnoob> I'm having a hard time knowing what my options are. Do I just have to farm out my gear work or buy a hobbing maching?
[21:17:22] <cncnoob> Or use plastic gears :(
[21:18:01] <cncnoob> All the hobbing videos I come across are making giant gears
[21:18:15] <cncnoob> I have never seen one that makes small gears
[21:19:28] <gregcnc> https://youtu.be
[21:20:49] <gregcnc> everything exists
[21:21:06] <cncnoob> haha
[21:21:16] <cncnoob> Now I know what to search for
[21:21:21] <cncnoob> I was looking for small gear hobbing
[21:21:25] <cncnoob> tiny gear hobbing
[21:21:37] <cncnoob> https://www.youtube.com
[21:21:44] <cncnoob> This one even has a part catcher
[21:22:12] <cncnoob> it isn't actually cutting anything, but based on the interval of that part catcher moving, it looks like it is pooping out gears pretty fast
[21:22:23] <gregcnc> no parts
[21:22:30] <gregcnc> they auto load too
[21:22:49] <gregcnc> i didn't find it in my history
[21:23:52] <gregcnc> lol haas live tool is a pneumatic drill
[21:24:02] <gregcnc> https://youtu.be
[21:24:03] <cncnoob> haha, yeah I saw that video
[21:25:45] <cncnoob> trying to find a Strausak Type 30 for sale
[21:26:07] <gregcnc> I tried to find some recently, but didn't spend a lot of time
[21:27:59] <gregcnc> I've been looking around for a small universal mill to build a hobber on with Linuxcnc control
[21:29:11] <gregcnc> small gang lathes can be useful https://www.youtube.com
[21:39:02] <gregcnc> cncnoob If you have a mill with 4th you can set it up to hob https://youtu.be
[22:02:55] <XXCoder> lol
[22:03:10] <XXCoder> might have 1-3 inch of snow, or 2-14 inch of snow on monday
[22:03:16] <XXCoder> depending on which modeling is correct

[22:56:19] <Jymmm> XXCoder: Well, it was mostly the size that I was joking about
[22:56:36] <XXCoder> yeah hence my joke lol
[22:56:45] <XXCoder> tiny welder, tiny hands
[22:58:50] <Jymmm> Though, you could carry it inside a tool box which is kinda cool
[22:59:09] <XXCoder> yeah
[22:59:18] <XXCoder> just double all amps
[23:02:36] <Jymmm> or half them actually (is what he was saying)
[23:02:51] <XXCoder> yeah im saying if you want 60 amps you double it to 120 amp
[23:04:52] <Jymmm> gotcha
[23:05:50] <XXCoder> that is weird. a way to overinflate the ratings of welder I guess

[23:30:11] <Tom_L> Jymmm i've seen small spot welders for those battery packs
[23:32:15] <Jymmm> Tom_L: for 18650 battery's? link?
[23:32:51] <Tom_L> no
[23:33:03] <Tom_L> not those specifically...
[23:33:20] <Tom_L> but they would put tabs on the ends
[23:33:27] <Tom_L> local battery shop
[23:34:19] <Jymmm> Tom_L: and they have a welder for them???
[23:34:34] <Tom_L> spot welder yes
[23:35:09] <Jymmm> I'm trying to think why would one need a battery powered spot welder for???
[23:35:23] <Tom_L> i didn't say it was battery powered
[23:35:36] <Tom_L> just a tiny welder for battery tabs
[23:35:52] <Jymmm> OH, you mean a spot welder to add tabs to 18650 batteries
[23:36:51] <Jymmm> battery weldering https://www.youtube.com
[23:38:14] <Tom_L> but then you can cook a hotdog with an extension cord too
