01:28 AM PL7icnc: hi last School Day here in Germany 1 Week Off
01:36 AM sensille: must be another germany than mine ;)
01:43 AM Deejay: moin
01:46 AM ItsFlipp_: YESS! Finalllly figured out my heat problem
01:47 AM ItsFlipp_: turns out my old coolant was just ... awful
01:47 AM ItsFlipp_: Polymer only, not cut with water
01:47 AM ItsFlipp_: switched to KoolMist 77 (1:32 with water), and presto, no more heat at all
01:57 AM PL7icnc: JesusAlos, Are You here
02:00 AM PL7icnc: im off
03:15 AM Loetmichel: mornin
03:22 AM gloops: wheres lostinsip when all the routers are on ebay https://www.ebay.co.uk/itm/Cnc-Router-Shopsabre-4896-4x8-or-5x8-Runs-great-servo-driven-with-ball-screws/392244518420?hash=item5b53985e14:g:3uQAAOSw96FcYa0r:rk:2:pf:1&frcectupt=true
04:23 AM XXCoder: gloops: dang! lol
04:23 AM XXCoder: erm
04:23 AM gloops: .
04:23 AM XXCoder: that looks like SAME machine
04:23 AM XXCoder: same pics even
04:24 AM gloops: he might have bid on that before - the one he was bidding on last time was a piranha
04:24 AM gloops: dont think he would have got that for his 5k limit
04:25 AM XXCoder: well one you linked is well below that lol
04:25 AM gloops: for now - probably go up a lot
04:25 AM XXCoder: yeah
04:26 AM gloops: something funny when hes selling on a 0 feedback a/c
04:28 AM jthornton: morning
04:28 AM gloops: morning jt
04:28 AM XXCoder: morning
04:31 AM jthornton: what's up this morning
04:31 AM XXCoder: just got home from work
04:31 AM XXCoder: so techinically its still thursday for me lol
04:32 AM gloops: nothing much, just loaded an engine up for the scrapyard, going to throw on whatever other scrap metal ive got laid about
04:32 AM jthornton: just waiting for the coffee pot to fire up
04:32 AM jthornton: I need to make a trip to the scrap yard and clean out my shop lol
04:33 AM gloops: ive been going to move this engine for 5 years lol
04:35 AM jthornton: I know that feeling about putting stuff off till years later, I had planned on painting the house last summer...
05:11 AM Tom_L: morning
05:26 AM jthornton: morning
05:26 AM XXCoder: morning
05:28 AM CNC_Brian: Morning all
05:29 AM CNC_Brian: Anyone know what the latency test executable is called?
05:29 AM CNC_Brian: Cant see it in bin
05:30 AM XXCoder: should be in linuxcnc menu but dunno name
05:30 AM jthornton: there are two of them latency-histogram and latency-test
05:31 AM jthornton: latency-histogram --help
05:31 AM jthornton: for options on that one
05:31 AM CNC_Brian: What folder do they live in JT?
05:31 AM jthornton: I'd guess /usr/local/bin maybe why
05:31 AM CNC_Brian: I have a rip install
05:32 AM jthornton: from the rip top level directory do this
05:32 AM jthornton: . ./scrips/rip-environment
05:32 AM jthornton: then run the latency test of your choice
05:32 AM CNC_Brian: Cool got it. Thanks.
05:32 AM jthornton: in a terminal of course
06:07 AM 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 ;)
06:08 AM XXCoder: lol
06:37 AM CNC_Brian: JT, your Stepgen spreadsheet and wiki article , Im confused.
06:37 AM CNC_Brian: So the Max jitter on the base thread on this old pc is 25000nS
06:46 AM CNC_Brian: Is max Jitter == worst case latency?
06:47 AM XXCoder: techinically you could run on really bad jitter
06:47 AM XXCoder: but it can cause problems
06:47 AM XXCoder: causing you to have to set quite low stepgen speed
06:48 AM CNC_Brian: Is 60,000nS Jitter on the Base Thread bad?
06:48 AM CNC_Brian: Seems high
06:48 AM jthornton: for a mesa card you don't use base thread
06:48 AM XXCoder: forgot what range is lol so dunno. but compared to my 14 year old pcs 15k yeah higher
06:48 AM CNC_Brian: No this is a different setup on an lathe
06:49 AM XXCoder: disable power saving systems any of em
06:49 AM jthornton: which spreadsheet and article are you talking about?
06:49 AM CNC_Brian: Im going through this : http://wiki.linuxcnc.org/cgi-bin/wiki.pl?TweakingSoftwareStepGeneration
06:49 AM jthornton: you can run the stepconf tool and see what the max step rate is for that latency
06:50 AM jthornton: that is very very very old
06:50 AM jthornton: last edit 7 years ago
06:50 AM XXCoder: CNC_Brian: be sure that your power savings configuration for that pc is all off.
06:51 AM CNC_Brian: Will do
06:51 AM XXCoder: dammit I meant power management
06:51 AM XXCoder: like hdd off, screen off, cpu controls etc
06:52 AM CNC_Brian: So using step config I have steplen =1 and stepspace = 0
06:52 AM CNC_Brian: Dirhold 44000
06:52 AM SpeedEvil: https://youtu.be/6XhXf4uKX0g?t=632 - how to improperly knurl a knob.
06:53 AM CNC_Brian: Base period is 100000
06:54 AM XXCoder: lo SpeedEvil thats not even close to wat jurling is
06:54 AM SpeedEvil: Indeed.
06:55 AM XXCoder: end result is sucky "kurling"
06:55 AM XXCoder: ... he cut it to size after doing that. might be bad idea if it ends up wrong size
06:56 AM XXCoder: that tool is interesting
06:56 AM SpeedEvil: Router planes are fun.
06:57 AM jthornton: hitting a file with a hammer what an idiot
06:57 AM XXCoder: granted he said only use old and basically dead file
06:57 AM SpeedEvil: if you don't care about the file, and are wearing face protection - meh.
06:57 AM SpeedEvil: Easy way to lose an eye though.
06:57 AM XXCoder: yeah you dont want to be blind or new Scarface
06:58 AM XXCoder: its likely boring just standing behind and little bit to left from your mob boss.
06:59 AM XXCoder: and you need to exercise to get to mob thug strength and look
06:59 AM XXCoder: boring. so dont risk your eye and face ;)
07:04 AM Jymmm: jthornton: FWIW... https://www.amazon.com/LASCO-17-5381-4-Inch-Thread-Adapter/dp/B00I8NS6Q6/
07:08 AM Jymmm: jthornton: I'm just taking it apart to connect to air hose =)
07:30 AM Jymmm: You think hitting a file is bad? This looks and sounds a tad scarry... https://www.youtube.com/watch?v=Kjr-AFLTkWo
07:30 AM Tom_L: i bet that guy's an awesome machinist too
07:30 AM XXCoder: Jymmm: so fancy intro
07:31 AM Jymmm: XXCoder: You hear him yelling out instructions to the guys at the end of the rod
07:32 AM XXCoder: hear?
07:32 AM Tom_L: at least the applied the ky first
07:32 AM XXCoder: heh I can SEE him yelling yes
07:32 AM Jymmm: XXCoder: I know you can't, but I'm saying that's what he's doing... left, right, etc
07:32 AM XXCoder: lol ok :)
07:33 AM XXCoder: didnt expect him to put on goggles
07:33 AM Jymmm: XXCoder: Then the machine starts to creak a bit, then his yelling gets intense =)
07:33 AM Tom_L: those are his kid's glasses
07:33 AM Jymmm: If that machine fubared, safety google aint gonna help
07:34 AM XXCoder: other guyb dont use it
07:34 AM Jymmm: It's solid rod, not tube either
07:34 AM XXCoder: indeed it wouldnt do crap as rod goes though head
07:35 AM XXCoder: wow hes talking so fast
07:36 AM Jymmm: Hey, no big deal, let me just carry around this hot metal like it's nothing https://www.youtube.com/watch?v=xzj60BM9oy0
07:40 AM XXCoder: roller parts is interesting
07:40 AM XXCoder: so big
07:42 AM Jymmm: the 75 ton 30ft ring you mean?
07:43 AM XXCoder: yea
07:52 AM 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.
07:52 AM CNC_Brian: Base thread was 100000 default stepconfig value
07:53 AM CNC_Brian: Stepper where missing steps, machine sounded horrible.
07:53 AM CNC_Brian: Though maybe the steps where too fast so slowed the base thread down to 200000
07:54 AM CNC_Brian: Even worse
07:54 AM CNC_Brian: Cranked the base threat unto 30,000 and runs like a dream
07:55 AM CNC_Brian: Im obviously not understanding the fundamentals here?
08:03 AM PL7icnc: Good Day
08:03 AM PL7icnc: seb_kuzm1nsky, are you here
08:03 AM PL7icnc: seb_kuzm1nsky, on the trutype tracer git you might add a howto
08:03 AM PL7icnc: i struggled to get it in 18.04
08:04 AM PL7icnc: libotf
08:04 AM PL7icnc: and "./configure
08:04 AM PL7icnc: as also non Linux People might not know make make install
08:20 AM PL7icnc: someone here
08:21 AM PL7icnc: maybe German
08:25 AM PL7icnc: pcw_home, are You Online
08:26 AM miss0r: Anyone in here got a good recipe for chipbreaking 42crmo4 on a lathe?
08:27 AM PL7icnc: miss0r, did you Consider chipbreaking bits
08:28 AM miss0r: chip break bits? :S
08:28 AM miss0r: as in; inserts with build in chip break? (if so, i've tried a few different ones now, with no success)
08:29 AM gregcnc: what are cutting parameters?
08:30 AM PL7icnc: miss0r, yes
08:30 AM miss0r: what I am currently running, gregcnc?
08:30 AM gregcnc: never had trouble with that material
08:30 AM miss0r: realy?
08:30 AM miss0r: what inserts are you using?
08:30 AM gregcnc: whatever
08:30 AM miss0r: ha...
08:30 AM PL7icnc: miss0r, https://www.youtube.com/watch?v=OOmdZn8sgF4
08:30 AM miss0r: I get a birdsnest nomatter what I do, it seems
08:32 AM miss0r: PL7icnc: I would get tired in a hurry, if I had to use toolbit steel for the cutting here : ]
08:33 AM 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
08:33 AM miss0r: But noone mentions any good inserts, that will do it for me
08:33 AM gregcnc: so what are cutting parameters?
08:33 AM miss0r: Problem is, the way I understand it; the material is too tough(elastic) for this to work proberly.
08:33 AM miss0r: ahh, hang on
08:35 AM miss0r: I've tried; 560-1220 rpm. This is a 38mm blank.
08:36 AM miss0r: I've tried feeding it in at anything between 0.054mm/rev to 0.2mm/rev
08:36 AM miss0r: and everything between 0.1-3mm doc
08:36 AM miss0r: on a large vareity of different inserts
08:36 AM rmu: sounds like an awful lot of permutations you tried there
08:37 AM miss0r: rmu: Honnestly I was not 100% scientific about it :D and I aborted a setup if it sounded off
08:37 AM miss0r: so, alot of different combinations of the above mentioned parameters have been tried
08:37 AM miss0r: and I have not so far been able to break the chip
08:37 AM gregcnc: I would go faster
08:38 AM SpeedEvil: That's only what - 2m/s?
08:38 AM miss0r: my max on this lathe is 1550rpm.
08:38 AM SpeedEvil: ah
08:38 AM rmu: get a bigger blank then ;)
08:38 AM gregcnc: yes ask the customer for a larger part
08:38 AM miss0r: :)
08:38 AM miss0r: hehe
08:39 AM miss0r: well. this is one of my own doing
08:39 AM miss0r: but I am planning to make 10 of these shafts to start with.
08:39 AM miss0r: (a land rover spare part, that is impossible to get in a proper quality)
08:39 AM SpeedEvil: just put a spinning thing next to the insert and reel it up
08:39 AM miss0r: SpeedEvil: To tell you the truth, I did comtemplate on that :)
08:40 AM gregcnc: my lathes are small so i use mostly Sandvik positive inserts
08:40 AM 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
08:40 AM gregcnc: dcmt070204-um 1125
08:42 AM rmu: you could pre-mill a groove
08:42 AM miss0r: I have some of quite simular geometry - they did not do the trick
08:42 AM miss0r: rmu: hehe, I could. but that would reak havok on my inserts :D
08:42 AM gregcnc: recommended VC is 135-225m/min and they do indeed like 150+
08:42 AM SpeedEvil: miss0r: Also - what's wrong with a chip-breaker stuc on top?
08:42 AM rmu: just make the chip thinner, without interruption, the inserts should be fine then
08:42 AM miss0r: SpeedEvil: I don't have one :D
08:43 AM SpeedEvil: miss0r: Seems shop-makable pretty easily
08:43 AM 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
08:43 AM SpeedEvil: :)
08:44 AM SpeedEvil: yeah - but a chip-breaker is a few minutes with dremel+ grinding wheel surely - faster than trying many feeds/speeds
08:44 AM 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
08:44 AM rmu: get a landrover, instead of driving in the mud you will end up rebuilding everything (including tooling) from scratch
08:45 AM miss0r: rmu: yes, ain't it beautiful? :)
08:45 AM 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
08:45 AM miss0r: this is why you gotta love it :)
08:45 AM rmu: reminds me of my dislike of closed systems. then you end up building your own CNC controls...
08:46 AM miss0r: I actualy have a new controller to add to my cnc mill at some point
08:46 AM SpeedEvil: rmu: I note open-source ECUs exist.
08:46 AM miss0r: completely wired up ect. I just haven't gotten around to programming it yet
08:46 AM SpeedEvil: rmu: I suspect you could do ECU on linuxcnc
08:46 AM SpeedEvil: (if you were insane)
08:47 AM rmu: ECU on linuxcnc? why? don't understand. ECU would be something for mikrocontroller
08:47 AM SpeedEvil: Indeed.
08:47 AM rmu: and I probably wouldn't trust my own ECU software
08:48 AM SpeedEvil: It was an aside - opensource ECU is already available, no need to roll your own from scratch
08:48 AM rmu: I had my "sudden, unexpected and not commanded acceleration" moments with my programs if you know what i mean
08:48 AM miss0r: rmu: This is what my new controller looks like: https://imgur.com/a/HOfatmZ
08:49 AM rmu: nice and tidy
08:49 AM miss0r: and realy complicated. the PCBs in the middle are translators, so I can use the original linear scales
08:50 AM miss0r: anyway. I best get going. I have to go pick up the kids. See you around
08:50 AM SpeedEvil: wave
08:50 AM rmu: i will bid on a second biesse rover 342, 25 year old CNC monster, for spare parts.
08:50 AM rmu: cu
10:01 AM Jymmm: never leave your keys in your car… https://youtu.be/GukldHaoPfA?t=1325
10:03 AM gregcnc: more importantly don't climb on the hood when someone who doesn't give a shit is trying to steal it
10:06 AM Jymmm: gregcnc: I like the "I pay for insurance so I can hit you"
10:07 AM gregcnc: well sure
10:08 AM gregcnc: this is an interesting machine https://youtu.be/Gv9_3xWp4V0?t=162
10:43 AM ziper: i leave my keys in the car and its no problem because i drive a piece of shit
10:51 AM Jymmm: gregcnc I wonder how much gold is lost in the process?
10:51 AM Jymmm: ziper: lol
10:51 AM gregcnc: i'm sure they collect it
11:00 AM hazzy-m: CNC_Brian: Did you notice if the rough motion with QtPyVCP only occurs when jogging? I'm noticing something similar and think it might be a bug
11:07 AM CNC_Brian: II first noticed it when I homed the Z axis
11:07 AM CNC_Brian: ]Its quite bad, I though I had a seizer ball screw.
11:10 AM 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
11:23 AM rmu: Doug Bowser (!) new head of nintendo usa!
11:26 AM SpeedEvil: Hmm. Just saw Matthias Wandel 'building a 3-legged stool'.
11:26 AM SpeedEvil: A 1-legged stool would be cool.
11:27 AM SpeedEvil: Couple of axes connected to the leg on the seat, so it balances.
11:43 AM fragalot: evenin'
12:14 PM gregcnc: what is tiatn going to do with a tormach
12:14 PM gregcnc: Titan
12:28 PM fragalot: gregcnc: probably get newbs to get a go at a cnc machine without risking his shiny ones?
12:31 PM fragalot: just watched the video.. i was close, btu not quite :)
12:58 PM syyl: i cant watch that titan guy
12:58 PM syyl: i throw up a bit in my mouth the moment he starts to talk/yell
01:01 PM PL7icnc: pcw_home, Are you online ?
01:12 PM fragalot: syyl: you mean you don't like the all out american style?
01:13 PM syyl: we have to machine faster or they will steal our jobs!
01:14 PM fragalot: I mean.... he's not entirely wrong
01:14 PM gregcnc: i've watched maybe two of his videos
01:14 PM fragalot: if you can do the same job with the same end result in less time than your competitor can..
01:14 PM gregcnc: and still make money.....
01:15 PM fragalot: that part is optional if you can push the other guy out of business first
01:15 PM gregcnc: bank still wants payment on the machines
01:16 PM fragalot: it worked for amazon
01:16 PM fragalot: :D
01:16 PM gregcnc: walmart did it too
01:18 PM gregcnc: syyl do you make many trepan tools?
01:19 PM syyl: for the lathe?
01:19 PM syyl: rarely
01:19 PM gregcnc: this will actually be a milling op
01:20 PM fragalot: same difference, no? :P
01:20 PM gregcnc: yes/no
01:23 PM gregcnc: It doesn't look like most tools have much side clearance
01:24 PM gregcnc: other than feeding slower is one edge a problem?
01:25 PM syyl: you want to run a trepaning tool in a boring head?
01:25 PM syyl: they cant have much clearance, otherwise they get very skiny
01:25 PM gregcnc: radial live tool in the lathe
01:25 PM syyl: ah ok
01:28 PM gregcnc: small feature Ø2.5, 2-3mm tall this looks good, but hss http://www.tristareng.com/images/port3_trepan_large.jpg
01:30 PM syyl: lots of parts?
01:30 PM gregcnc: aluminum, maybe 100
01:31 PM syyl: i would be tempted to just mill it
01:31 PM syyl: for such a small feature
01:32 PM gregcnc: I should see how mishapen it gets with a regular endmill
01:34 PM gregcnc: just want to avoid a separate operation. my design so I get to play with it
01:34 PM syyl: livetool has only collet chuck, right?
01:34 PM gregcnc: yes
01:35 PM syyl: if i felt like beeing experimental, I would draw/design a solid carbide tool in cad
01:35 PM syyl: and grind it that way
01:36 PM gregcnc: https://muskegontool.com/images/stories/products/trepantools_34736large.jpg
01:36 PM gregcnc: this is obviously large, but a single cutting edge cut from solid
01:36 PM syyl: can you see that picture in the link?
01:37 PM syyl: https://www.instagram.com/p/BQit9F1B4Wb/
01:37 PM gregcnc: yes, just liek that
01:37 PM syyl: thats what i would grind, just smaller ;)
01:37 PM syyl: and so it cuts on size without need adjusting by a boring head
01:39 PM gregcnc: yes, that's what I'm after. shank is concentric to the feature produced
01:40 PM gregcnc: probably even have a splint blank in the box
01:40 PM gregcnc: Thanks!
01:40 PM syyl: no problem :D
01:40 PM syyl: not sure if i was of any help ;)
01:41 PM gregcnc: I started with a far too complicated idea, this is better
01:41 PM syyl: :)
01:41 PM gregcnc: I probably even saw that on insta, but forgot
01:54 PM 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.
02:04 PM gregcnc: yes, those are ok for coring stock
02:12 PM fragalot: does anyone know if there is an equivalent to pallet changers for lathes?
02:12 PM gregcnc: part loaders?
02:14 PM fragalot: part loaders, and a way to swap jaws for different size parts
02:15 PM fragalot: starting with hard 3-jaws set at ~40mm, sub-spindle with soft jaws for 38mm
02:15 PM fragalot: switching to 10mm and 8mm soft
02:15 PM fragalot: (or collet)
02:15 PM gregcnc: chucks are not automated like that
02:15 PM fragalot: indeed they are not
02:15 PM fragalot: hence me asking :D
02:16 PM gregcnc: what are you asking then?
02:17 PM methods_: http://www.positrol.com/pdf/chuck_change.pdf
02:17 PM methods_: i think they make quick changeover chucks for automated changeovers
02:17 PM fragalot: I know that schunk makes chucks that have jaws that can be actuated with a robot arm to adjust them
02:18 PM fragalot: just figured i'd ask if there were alternative techniques that I hadn't thought of, or didn't know about
02:18 PM methods_: https://www.mmsonline.com/products/system-automates-workholding-change-overs
02:19 PM fragalot: thanks methods_, looks interesting
02:19 PM gregcnc: wow who uses that stuff?
02:19 PM methods_: someone running lights out
02:19 PM fragalot: gregcnc: ^
02:22 PM gregcnc: OK I just imagine if volume is high enough to run lights out, how often do you need to change fixturing?
02:23 PM fragalot: low volume high mix
02:23 PM methods_: ah yeah i guess if you're trying to be "agile" or whatever the new buzz word is
02:23 PM methods_: yeah
02:24 PM gregcnc: but jobs would have to repeat to make sense?
02:24 PM methods_: i would think so
02:24 PM 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
02:24 PM fragalot: gregcnc: yes
02:24 PM methods_: i've never had much luck running a job i've never run before lights out lol
02:24 PM gregcnc: so one shift sets up, and the machine runs three
02:25 PM fragalot: why run the machine for 3 shifts to produce 4000 parts of something if you only need 100?
02:25 PM fragalot: if you can reduce the setup time of the machine (again, this is for 100% repeat parts) to minutes
02:25 PM fragalot: just run the 100 parts & move on to the next one
02:26 PM gregcnc: what about tools?
02:26 PM fragalot: that's another conundrum i'm looking into
02:26 PM 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
02:27 PM fragalot: pallet changers, huge tool banks, all exists "off the shelf"
02:27 PM methods_: i mean all that sandvik capto stuff is made for automated tool changeovers
02:28 PM fragalot: methods_: good point, those could be automated too, external to the machine, I guess
02:29 PM methods_: https://www.youtube.com/watch?v=-g184-UhbTI
02:31 PM methods_: https://www.youtube.com/watch?v=3d-kPBbxb0Q
02:31 PM methods_: better video of okuma setup
02:31 PM methods_: with tool changes on turret with capto
02:33 PM fragalot: i've been looking at that collet system from schunk
02:34 PM fragalot: nearly exactly what I was looking for :D
02:35 PM gregcnc: how much money in that okuma clip?
02:35 PM methods_: yeah that snap in collet system
02:35 PM methods_: for that cell?
02:35 PM gregcnc: yes
02:35 PM methods_: sheesh probably 1.5million
02:35 PM methods_: maybe more
02:35 PM methods_: i dont' know i've never had the chance to get something like that quoted
02:35 PM methods_: lol
02:36 PM methods_: probably more like 3-4 million
02:46 PM methods_: heh mazak just changes the chuck jaws
02:46 PM methods_: https://www.youtube.com/watch?v=OqDL3jsdUB4
02:46 PM methods_: at 2:15
02:47 PM fragalot: those mazaks are purdy little things aren't they
02:48 PM methods_: i'm kinda partial to okuma myself
02:48 PM fragalot: i've got no preference as long as it's beefy & fast
02:50 PM methods_: yeah i'm always stuck on whatever so i really don't care either
02:50 PM methods_: but those okumas are reallllllyyy nice
02:50 PM methods_: the mazaks aren't too bad either
02:50 PM methods_: except for all that mazatrol silliness
02:51 PM fragalot: the controls we're going to go for is probably going to be something from siemens
02:52 PM fragalot: just to keep everything talking to eachother without having to jump through weird hurdles
02:52 PM methods_: ah well i guess that kinda limits you
02:53 PM fragalot: a little
02:53 PM methods_: i don't even know who uses siemens controllers besides dmg
02:54 PM methods_: but now that they're dmg/mori i don't know what they use
02:54 PM methods_: mori was mainly fanuc
02:54 PM fragalot: they still supply siemens
02:54 PM fragalot: if you ask for it
03:50 PM Deejay: gn8

04:06 PM gloops: !seen lostinsip
04:19 PM gloops: whoo i won a set of dolls house moulding cutters
04:19 PM gloops: i wonder what i can make with these
04:37 PM XXCoder: huh doll house moulding cutters?
04:43 PM gloops: yeah its what they use to make parts for dolls houses, window moldings, skirting boards, cornices etc
04:45 PM gloops: https://www.trenddirectuk.com/trend-router-cutters/trend-router-cutter-sets/trend-dolls-house-cutters/trend-dolls-house-cutter-sets
04:45 PM gloops: i got an unused set off ebay for £29
04:45 PM gloops: basically minature moulding bits
05:00 PM XXCoder: interesting
05:00 PM XXCoder: you haved over 100 pounds dang
05:04 PM gloops: i think they might come in handy for small stuff, i havent got any plans to be making dolls houses lol
05:04 PM XXCoder: *saved
05:05 PM XXCoder: use cnc with it to make really fancy paint or picture frames?
05:05 PM gloops: yeah i stuck a 50 bid on them as i was going out, expected more interest on them
05:06 PM gloops: XXCoder stuff like that yeah, quite a lot of stuff where detailed edging is used - a lot quicker to send a moulding cutter round a vector than car it all out with a ballnose
05:06 PM gloops: carve
05:22 PM XXCoder: yeah
05:29 PM gregcnc: linuxcnc powered tool & cutter grinder https://www.kaindl.de/en/machines/machines-mill/fsm.html
05:32 PM gregcnc: https://youtu.be/aIV9WmEDl90
05:33 PM XXCoder: dang
06:13 PM ItsFlipp_: Tom_L: you see that I got my heat buildup problem all solved?
06:13 PM ItsFlipp_: (can't remember who else was helping me diagnose)
06:13 PM ItsFlipp_: but thanks all
06:13 PM 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)
06:14 PM ItsFlipp_: and thus all it did was burn/heat up and didn't actually cool at all
06:14 PM ItsFlipp_: switched to a 32:1 dilution of KoolMist 77 and bingo, no more heat at all
06:15 PM jthornton: glad you got it sorted out
06:15 PM ItsFlipp_: ah, yeah, thanks for the help :)
06:16 PM 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
06:16 PM ItsFlipp_: finally finished the part last night in the vise
06:24 PM Tom_L: cool
06:27 PM Tom_L: now if JT-Shop could get the chicken door sorted out...
06:27 PM Tom_L: need a good week of operation...
06:28 PM Tom_L: got my macro doing RH, LH internal & external threads finally
07:05 PM Jymmm: Nitro powered chainsaw... https://youtu.be/c1X3-5uD8aE?t=149
07:07 PM XXCoder: what the heck why is I not subbed again
07:12 PM Jymmm: jt-m[m]: You need to make of of these for your tractor https://youtu.be/398CIi9Pp90?t=218
07:16 PM Jymmm: A one HORSE powered log splitter...https://youtu.be/398CIi9Pp90?t=289
07:19 PM XXCoder: 5:45 I like that one
07:22 PM XXCoder: 9:45 LOL modified tire. slightly less than safe lol
07:22 PM XXCoder: pretty effectve I admit.
07:49 PM 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?
07:49 PM cncnoob: https://www.haascnc.com/productivity/spindles/sub-spindle-a2-5.html
07:51 PM XXCoder: it transfers from main spindle so you can finish other side of part without losing position
07:51 PM XXCoder: can be very effective
07:52 PM cncnoob: So the work piece is moved from the main spindle to the finishing spindle automatically?
07:52 PM XXCoder: fancy machine can move finishing spindle in and grip part, then bpth main spindle and finishing spindle spin as its cut off rod
07:52 PM XXCoder: that one dunno but swiss lathe I saw does.
07:52 PM XXCoder: looks like yes
07:53 PM 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.
07:53 PM cncnoob: It is an $18K option on a Haas ST-10
07:53 PM gregcnc: yeah not cheap
07:53 PM XXCoder: if you make thousands of parts thats worth all the 18k.
07:53 PM gregcnc: productivity can be tremendous
07:54 PM cncnoob: I guess it is only of benefit on 2 op parts right?
07:54 PM XXCoder: swiss lathe at work already made tens of thousands
07:54 PM gregcnc: which parts aren't 2 op?
07:54 PM XXCoder: is there such thing as one op part?
07:54 PM cncnoob: I've never run a lathe, but I would think so?
07:54 PM XXCoder: swiss lathe will take a bit to cover itself in profit tho lol its one million bucks usd
07:55 PM gregcnc: many parts can be made by simply parting off
07:55 PM XXCoder: if you dont care about one side finish sure
07:55 PM gregcnc: 1M$ swiss?
07:55 PM XXCoder: swiss lathe yeah
07:55 PM gregcnc: which
07:55 PM XXCoder: dunno didnt look at model #
07:56 PM XXCoder: whats interesting is that it uses swiss oil.
07:56 PM XXCoder: no coolant
07:56 PM gregcnc: they all do
07:57 PM gregcnc: what's interesting is that some use the same oil for the ways
07:57 PM XXCoder: we have one barrel and one chip bin thats reserved for it. oil must be pricy!
07:57 PM gregcnc: yeah
07:58 PM gregcnc: kilobuck a drum
07:58 PM 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
07:58 PM XXCoder: interesting. what they do is leave chips in bin for while so oil drains down
07:58 PM cncnoob: I'm comfortable with LinuxCNC, but have only used it on mills
07:58 PM cncnoob: any suggestions on a lathe to run LinuxCNC on?
07:59 PM XXCoder: you want machine that is completely insurable and warrantable if its pretty expensive one
07:59 PM cncnoob: If I can't find a suitable machine that I can use LinuxCNC with, I will likely get something like this:
07:59 PM cncnoob: https://www.haascnc.com/content/haascnc/en/build-and-price/choose-options.CL-1.html
08:00 PM gregcnc: that's an expensive machine for it's capacity
08:00 PM cncnoob: It is fairly limited, but it is also small and inexpensive compared to many other options
08:00 PM cncnoob: I'm open to better options
08:00 PM XXCoder: i dont really like haas
08:00 PM XXCoder: none of machines I ran really impressed me
08:01 PM cncnoob: What don't you like?
08:01 PM XXCoder: hard to say really
08:01 PM XXCoder: just feel ehh
08:01 PM cncnoob: I have never used a Haas machien
08:01 PM XXCoder: not as bad as hurco LOL
08:01 PM cncnoob: but I like the fact that they have a lot of learning material on line
08:01 PM gregcnc: if you want new go for it, but there is a lot on the used market
08:01 PM XXCoder: I rather run old fadal 88 than hurco
08:01 PM cncnoob: and there is a factory outlet 10 minutes from me
08:02 PM XXCoder: if someone asked me to work hurco or quit.. I would... work at hurco but maybe seek other jobs lol
08:02 PM XXCoder: hint: DONT BUY HURCO lol
08:03 PM cncnoob: noted :)
08:03 PM gregcnc: big jump from dead machine to put linuxcnc on to new haas
08:03 PM gregcnc: just buy a used machine that runs
08:03 PM gregcnc: or needs some work
08:04 PM cncnoob: dead machine?
08:04 PM gregcnc: I assume dead if you want to retrofit?
08:04 PM cncnoob: My machine runs, but I don't have a lathe
08:04 PM gregcnc: you asked about a lathe for linuxcnc
08:04 PM cncnoob: I have a mini mill that I converted with a 4th axis to do proto typing
08:05 PM 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
08:05 PM XXCoder: yeah'
08:05 PM cncnoob: I have a project, I don't want another project, that is why I'm looking to buy new
08:05 PM gregcnc: I started a lathe linuxcnc retrofit, but bought a lathe before it was done
08:06 PM 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
08:07 PM Tom_L: i did a cad cam part for a lcnc lathe but most of the time we just MDI the parts
08:08 PM cncnoob: Another reason I was looking at that Haas lathe is because it could do tiny stuff
08:08 PM gregcnc: my lathe is about that size
08:08 PM cncnoob: the largest thing I would make would be 1" diameter
08:08 PM cncnoob: Most would be 1/4"
08:08 PM cncnoob: Those would be gears
08:09 PM gregcnc: it won't cut gears?
08:09 PM cncnoob: Why not?
08:09 PM gregcnc: you need a hobber
08:10 PM cncnoob: Can't you use those discs?
08:10 PM cncnoob: I've seen like an 8 pack of discs that cut gears
08:10 PM cncnoob: something like this
08:10 PM cncnoob: https://www.amazon.com/PA14-1-Involute-Cutters-Milling-Machine/dp/B00T2SQKDM/ref=sr_1_1?crid=2G1Z05HNI3LNE&keywords=gear+cutter+set&qid=1550887697&s=gateway&sprefix=gear+cutter%2Caps%2C145&sr=8-1
08:11 PM gregcnc: in the CL-1??
08:11 PM cncnoob: Yeah. Why not?
08:11 PM XXCoder: for number of teeth and angles nice
08:12 PM XXCoder: cncnoob: btw one of reasons I hate hurco, if I pause it would suddenly take spindle to z zero
08:12 PM XXCoder: if its cutting though something on side.. well too bad.
08:12 PM gregcnc: you'll want to look into it a bit more, that just isn't possible on most 3 axis lathes
08:13 PM gregcnc: I wish I could make gears on mine, but I can't
08:13 PM cncnoob: There is a C axis option
08:13 PM cncnoob: and with live tooling
08:13 PM cncnoob: I thought it should be possible
08:13 PM gregcnc: no
08:16 PM gregcnc: If you built a special live tool, you could, assuming there is space in that machine
08:18 PM cncnoob: I would really like to find a solution where I can cut gears and other small round parts on one machine
08:19 PM gregcnc: that's a big ask
08:19 PM 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?
08:19 PM cncnoob: Or use plastic gears :(
08:20 PM cncnoob: All the hobbing videos I come across are making giant gears
08:20 PM cncnoob: I have never seen one that makes small gears
08:21 PM gregcnc: https://youtu.be/6OqG1wziJtc
08:23 PM gregcnc: everything exists
08:23 PM cncnoob: haha
08:23 PM cncnoob: Now I know what to search for
08:23 PM cncnoob: I was looking for small gear hobbing
08:23 PM cncnoob: tiny gear hobbing
08:24 PM cncnoob: https://www.youtube.com/watch?v=8lZaXi5NoeE
08:24 PM cncnoob: This one even has a part catcher
08:24 PM 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
08:24 PM gregcnc: no parts
08:24 PM gregcnc: they auto load too
08:25 PM gregcnc: i didn't find it in my history
08:26 PM gregcnc: lol haas live tool is a pneumatic drill
08:26 PM gregcnc: https://youtu.be/FqtbzWo_BWQ?t=52
08:26 PM cncnoob: haha, yeah I saw that video
08:28 PM cncnoob: trying to find a Strausak Type 30 for sale
08:28 PM gregcnc: I tried to find some recently, but didn't spend a lot of time
08:30 PM gregcnc: I've been looking around for a small universal mill to build a hobber on with Linuxcnc control
08:31 PM gregcnc: small gang lathes can be useful https://www.youtube.com/watch?v=ksd5atJkfFo
08:41 PM gregcnc: cncnoob If you have a mill with 4th you can set it up to hob https://youtu.be/ZhICrb0Tbn4
09:05 PM XXCoder: lol
09:05 PM XXCoder: might have 1-3 inch of snow, or 2-14 inch of snow on monday
09:05 PM XXCoder: depending on which modeling is correct
09:31 PM Jymmm: XXCoder: I found you a welder https://www.amazon.com/gp/product/B077G7P71L/
09:31 PM XXCoder: huh
09:32 PM Jymmm: XXCoder: it fits in your hand
09:33 PM XXCoder: dude im not trump
09:33 PM Jymmm: I have no idea what that means
09:34 PM infornography: Anyone have hot tweezers? Are they actually useful?
09:34 PM XXCoder: honestly i didnt ask anyone to loom for welder thats why im confused
09:34 PM Jymmm: for SMT work
09:34 PM Jymmm: XXCoder: https://www.youtube.com/watch?v=XI1phUMqOKo
09:40 PM XXCoder: interesting video
09:58 PM Jymmm: XXCoder: Well, it was mostly the size that I was joking about
09:59 PM XXCoder: yeah hence my joke lol
09:59 PM XXCoder: tiny welder, tiny hands
10:01 PM Jymmm: Though, you could carry it inside a tool box which is kinda cool
10:01 PM XXCoder: yeah
10:01 PM XXCoder: just double all amps
10:05 PM Jymmm: or half them actually (is what he was saying)
10:05 PM XXCoder: yeah im saying if you want 60 amps you double it to 120 amp
10:07 PM Jymmm: gotcha
10:08 PM XXCoder: that is weird. a way to overinflate the ratings of welder I guess
10:11 PM Jymmm: as is anything from china,
10:12 PM XXCoder: I usually use 80% but that one takes the cake. 50% lol
10:13 PM Jymmm: I derate china batteries by 50% usually
10:13 PM XXCoder: i dont buy china batteries usually
10:13 PM XXCoder: risky.
10:14 PM Jymmm: I buy 18650's
10:14 PM XXCoder: ones thats not half sand?
10:17 PM Jymmm: WTF https://www.dx.com/p/trustfire-protected-18650-3-7v-true-2400mah-rechargeable-lithium-batteries-2-pack-2006435
10:18 PM Jymmm: Can't deliver to USA ?!?!?!?!?!?!?!
10:19 PM XXCoder: i have link for 18650 a second

10:21 PM Jymmm: I like that they have "fasttech tested capacity
10:22 PM XXCoder: 6 bucks each bit more money but tested not bad
10:22 PM XXCoder: looks same as my link also
10:22 PM Jymmm: and 3400 not 2400
10:23 PM XXCoder: indeed
10:23 PM Jymmm: Nice, they have the test graph in the pics
10:24 PM Jymmm: Here ya go... https://www.fasttech.com/products/1420/10000377/1053200-trustfire-tf-18650-3-7v-3000mah-protected

10:26 PM XXCoder: why the quotes
10:28 PM Jymmm: 2019-02-22.20:22:52 Jymmm: oh, nm
10:29 PM XXCoder: yeah
10:32 PM Tom_L: Jymmm i've seen small spot welders for those battery packs
10:34 PM Jymmm: Tom_L: for 18650 battery's? link?
10:35 PM Tom_L: no
10:35 PM Tom_L: not those specifically...
10:35 PM Tom_L: but they would put tabs on the ends
10:35 PM Tom_L: local battery shop
10:36 PM Jymmm: Tom_L: and they have a welder for them???
10:37 PM Tom_L: spot welder yes
10:37 PM Jymmm: I'm trying to think why would one need a battery powered spot welder for???
10:37 PM Tom_L: i didn't say it was battery powered
10:38 PM Tom_L: just a tiny welder for battery tabs
10:38 PM Jymmm: OH, you mean a spot welder to add tabs to 18650 batteries
10:39 PM Jymmm: battery weldering https://www.youtube.com/watch?v=Dx3504M1MHY
10:40 PM Tom_L: but then you can cook a hotdog with an extension cord too
11:05 PM Jymmm: battery powered welder... https://www.youtube.com/watch?v=Dx3504M1MHY
