02:40 AM pink_vampire: is there a way to control the location of the "debug messages"?
03:18 AM pink_vampire: https://web.archive.org/web/20101020051846/http://www.isd.mel.nist.gov/projects/_emc/
03:27 AM Deejay: moin
03:27 AM pink_vampire: hi Deejay
04:13 AM XXCoder: jymmm: now impiles it was new. it is not.
04:13 AM pink_vampire: hi XXCoder
04:13 AM XXCoder: hey
04:13 AM XXCoder: work was so boring.
04:14 AM pink_vampire: do you know where is the setting of the location for the "debug messages"?
04:15 AM XXCoder: unfortunately no but jt should be on soomish
04:16 AM XXCoder: $12,000 left on car yayyy :P
04:16 AM XXCoder: i hate debt.
04:16 AM pink_vampire: i want to move them abit, it cover the pyvcp menu
04:16 AM sensille: debt is modern slavery
04:17 AM XXCoder: yep
04:18 AM XXCoder: unfortunately i needed a newer car. tired of fix or repair daily
04:18 AM pink_vampire: my car is old
04:18 AM sensille: now, work harder!
04:18 AM XXCoder: nah didnt need to increase work to afford loan payments.
04:19 AM XXCoder: i dont go into red. ever.
04:58 AM jthornton: morning
04:59 AM pink_vampire: hi jthornton
05:00 AM XXCoder: hey jt
05:00 AM XXCoder: jthornton: job was boring and annoying lol
05:00 AM XXCoder: I hate finish requirement jobs :(
05:00 AM XXCoder: 32 finish ugh
05:00 AM jthornton: surface finish?
05:00 AM XXCoder: yeah
05:01 AM XXCoder: I have to check each few parts. its stainless steel so it wears tools
05:01 AM XXCoder: tools are techinically still good but no good for keeping finish below 32.
05:06 AM jthornton: I've never had to do a finish requirement so I know less than nothing about it lol
05:06 AM XXCoder: we got special equipment for measuring it lol it looks like long smallish 1"x1" box attached to height gauge
05:07 AM XXCoder: it has arm with pin that kinda looks like vinyl player thing
05:07 AM XXCoder: it moves in slowly then returns, then controller box displays result
05:11 AM Tom_L: morning
05:11 AM XXCoder: yo
05:11 AM jthornton: morning
05:11 AM XXCoder: today was another record busting day
05:11 AM XXCoder: 79f, orginial record was 63f
05:11 AM XXCoder: 16 degrees higher than old record.
05:13 AM Tom_L: yup, day older and still here :)
05:13 AM XXCoder: tomorrow probably will be 90f :P kidding
05:13 AM XXCoder: this does not bode well for summer for this region :(
05:13 AM Tom_L: gotta dry up all the moisture you got
05:14 AM XXCoder: thats it, spring is supposed to be rain forever
05:14 AM XXCoder: this is rainforest biome after all
05:14 AM jthornton: weather will be nice here for the next few days
05:14 AM Tom_L: finish can be a PITA sometimes...
05:14 AM XXCoder: summer should have rain in least once a week but havent been true for years now
05:14 AM XXCoder: Tom_L: no shit
05:16 AM XXCoder: thankfully finish is very rare
05:16 AM XXCoder: and im always "lucky" on getting those jobs though
05:17 AM Tom_L: they must know you can do it
05:17 AM XXCoder: nobody likes that job
05:17 AM XXCoder: "yo do it"
05:17 AM XXCoder: lol
05:18 AM Tom_L: jthornton, got 2.8 running last night thanks to dgarr & andy
05:18 AM XXCoder: but yeah I can do it, just dislike it. its far from worse though
05:19 AM Tom_L: do they have finish inspection samples?
05:19 AM jthornton: what was the issue for you?
05:19 AM Tom_L: 2
05:19 AM Tom_L: .py wrong version
05:20 AM Tom_L: and near component aparently has a bug in 2.7 because i had it commented out going the spindle signal
05:20 AM Tom_L: and 2.8 caught it
05:20 AM Tom_L: spindle.0.at-speed
05:21 AM Tom_L: worked fine in 2.7
05:28 AM XXCoder: interesting https://futurism.com/the-byte/3d-printed-electric-motorcycle-tron
05:39 AM XXCoder: ohhh https://www.youtube.com/watch?v=xP1gtXNM844
05:40 AM jthornton: too much trying to be an actor and failing badly
05:41 AM pink_vampire: is there a way to display only 3 decimal points in a debug messages?
05:42 AM XXCoder: jthornton: last video?
05:42 AM jthornton: yea
05:42 AM XXCoder: yeah hes not great lol but like to see projects of his
05:42 AM jthornton: I bail pretty quick when they are waving hands and trying to act lol
05:42 AM XXCoder: i definitely want to try that one. epoxy recreation of bug in amber
05:42 AM jthornton: pink_vampire: you would have to dig into the code
05:44 AM XXCoder: that video pre-dates his discovery that vacuum could fix bubbles, but even later high pressure does it easier
05:44 AM pink_vampire: i already solved the location of the debug messages , now i just want to reduce the default 6 decimal points to something more readable like 2 or 3
05:47 AM jthornton: is it python?
05:47 AM pink_vampire: i have no idea
05:48 AM pink_vampire: i mean if you send a command from a gcode file to display a value, you get xx.xxxxxx
05:49 AM jthornton: you said you found the location of debug or did you move the debug in axis?
05:51 AM pink_vampire: in the message it give you 6 decimal points , i want to make it shorter so i don't need to change anything
07:03 AM jthornton: https://forum.linuxcnc.org/41-guis/36239-qtpyvcp-mill-touch-screen?start=10#129156
08:30 AM gregcnc: Wow https://www.practicalmachinist.com/vb/machinery-for-sale-or-wanted/never-used-brand-new-perfect-1984-vintage-south-bend-10k-lathe-359846/
08:35 AM SpeedEvil: hah
08:36 AM * Loetmichel just retruned from a 450km delivery drive roundtrip in the new old BMW 525i... its a LOT more comfortable at 230kph than the Opel Omega... its thirsty at that speed though. 46 liters premium petrol for the trip. And i drove "tame" 130kph on the way back :-)
08:56 AM miss0r2: germans and their "no speed limit"...
08:56 AM miss0r2: :)
08:59 AM Loetmichel: what?
08:59 AM Loetmichel: 230kph isnt that fast. barely 140 mph!
09:00 AM miss0r2: Don't translate that for me, I'm from Denmark, remember? :D
09:00 AM miss0r2: It is pretty fucking fast :D
09:02 AM gregcnc: fast enough they send out a hearse vs amubalnce?
09:02 AM gregcnc: in case of wreck
09:06 AM miss0r2: something like that :D
09:11 AM jymmm: More like a tractor to bury on site
09:15 AM Loetmichel: ah sorry ;)
09:16 AM Loetmichel: gregcnc: depends on the werck and the car
09:16 AM Loetmichel: on a motorcycle its pretty much a death sentence
09:16 AM Loetmichel: in a BMW 5xx touring: not so much
09:17 AM Loetmichel: unless you hit something solid at full speed
09:23 AM jymmm: Even a blowout, or something in the road and you are pretty much screwed at that speed
09:26 AM Elmo40: what? the roads are perfectly smooth and clean? say it ain't so.
09:26 AM Elmo40: even racetracks are filthy.
09:27 AM Elmo40: gregcnc, nice lathe! you getting it?
09:28 AM gregcnc: no I have a beat up clausing, but I am looking for something like a Harrsion 250 or 300
09:28 AM gregcnc: Harrison
09:30 AM Elmo40: that lathe was $2,800 brand new in 1984.
09:31 AM Elmo40: even with inflation, that lathe would only equate to $6,300 today.
09:32 AM Loetmichel: jymmm: as i said: not my personal experience
09:33 AM Loetmichel: if there is nothing you can hit (like bridges) a blowout at 230kph is pretty harmless...
09:33 AM Loetmichel: piroetted 3 times, got the car back under control and slowed down to a standstill on the shoulder
09:34 AM Loetmichel: the rim was trash though
09:34 AM Elmo40: ;-)
09:34 AM gregcnc: A guy I knew fliped in a E36 convertible at 30MPH due to blow out.
09:51 AM SpeedEvil: Convertibles are great. The feeling of asphalt in your hair.
09:52 AM Loetmichel: gregcnc:like that one? -> https://www.youtube.com/watch?v=ERJ9QSWRE58&t=192s
09:52 AM Loetmichel: :-)
09:52 AM Loetmichel: had no blowout in that, but shortly after the video the engine threw a rod at 160kph
09:52 AM Loetmichel: wasnt funny
09:53 AM Loetmichel: no crahs though, but quite a bit of oil on the autobahn
09:53 AM Loetmichel: pushed the clutch fast enough to prevent a spinout
10:02 AM gregcnc: my E36 is fine except for interior falling apart
10:38 AM jymmm: gregcnc: spray foam and it's good as new ;)
10:42 AM mozmck: Loetmichel: I thought you drove on the left side in Deutschland?
10:47 AM Loetmichel: mozmck: hu?
10:47 AM Loetmichel: germany isnt GB ;)
10:47 AM mozmck: Guess I was wrong then!
10:53 AM beachbumpete1: JEEZ is it Friday yet? ;)
10:54 AM X704 is now known as tiwake
10:55 AM Loetmichel: beachbumpete1: nope, still a day to go
10:56 AM beachbumpete1: GAAhhhhh
11:02 AM Lcvette: hey all
11:03 AM Lcvette: any of you running a USFF small box pc with mesa ethernet? if so which and how is latency?
11:13 AM gregcnc: huh youtube filters are intentionally broken right now
11:24 AM jymmm: filters?
11:36 AM SpeedEvil: Filters have aways been ratehr broken.
11:36 AM SpeedEvil: I mean - how can I say I want to see videos older than 10y, for example.
11:43 AM Tom_L: ask siri?
11:44 AM Tom_L: bing?
11:44 AM Tom_L: beachbumpete1 day draggin on for ya?
11:55 AM Lcvette: Tom_L: what little pc's are you running with good latency now days?
11:55 AM Lcvette: i need one for a little lathe build i am doing
11:55 AM Lcvette: ethernet or pcie
11:55 AM Lcvette: for mesa's
11:56 AM pink_vampire: someone know how can I display only 3 decimal places in the "debug messages" instead the default 6 decimal places?
12:02 PM Deejay: in metric, 3 decimal places would be enough for me ;)
12:06 PM pink_vampire: for the stuff that i do even 2 will be fine
12:10 PM pcw_home: Lcvette: I find used Elite 8300s are pretty nice if you turn off the Intel Ethernet spyware
12:11 PM pcw_home: https://www.ebay.com/itm/HP-Compaq-Elite-8300-USDT-Quad-Core-i5-3470S-2-9GHz-4GB-RAM-NO-HDD-Boot-to-BIOS/153412188014?hash=item23b814376e&enc=AQADAAAC8FjVrDbVsZ8oH%2F8PNHtt9VX4%2Fw7FZcmMuqsX8uaFEduVAORwm7csXI04Q4ZWnmBewRODCkdRAsYV870TAWxhT1HocB%2B3oxar29MmWQrYDXQfX%2BT5DJwt4wMtWQFivEEW551pxp5Ua1W2GarMX3UZKY85kyoY25%2FiefMPAOR8W9Sa3UBTIxBAVsxfSWywZGOZZvKSCr6Vp6t5baK2tN7EhSVhNGB%2FSKijxPgmIbNXiT3iian1bhCk2tWaFm6aN%2F%2BOTNhX%2F0

12:11 PM Lcvette: i was just looking at gigabytes website and it looks like the newest J4005 D2P built in has an M.2 socket :D
12:11 PM Lcvette: pcw_home: have any experience with them?
12:12 PM jymmm: Gawd, I hate when ebay does that =(
12:12 PM pcw_home: Oops so sorry for the ginormous URL
12:12 PM jymmm: https://www.ebay.com/itm/HP-Compaq-Elite-8300-USDT-Quad-Core-i5-3470S-2-9GHz-4GB-RAM-NO-HDD-Boot-to-BIOS/153412188014
12:12 PM jymmm: Ok, does anyone have a clue... https://i.imgur.com/b0knqAi.jpg
12:13 PM pcw_home: Yes its one of the few cheap PCs that works up to about 4 KHz with Ethernet
12:13 PM Lcvette: yeah?
12:13 PM Lcvette: its good?
12:13 PM pcw_home: Yeah but you have to turn off AMT or its crappy
12:14 PM Lcvette: no clue what that is
12:14 PM Lcvette: lol
12:14 PM pcw_home: I forget what that's an acronym for
12:14 PM Lcvette: as long as i can use the M.2 hard drive to keep it tiny
12:14 PM Lcvette: im good
12:15 PM pcw_home: This is old so SATA only
12:15 PM jymmm: pcw_home: as opposed to what? MFM?
12:15 PM pcw_home: SMD?
12:15 PM Lcvette: https://www.gigabyte.com/us/Motherboard/J4005N-D2P-rev-10#kf
12:16 PM jymmm: pcw_home: ah
12:16 PM pcw_home: I think the 4005s are OK I have a slower version (N3355)
12:16 PM Lcvette: this one says M.2 for sata and pcie NVMe SSD
12:16 PM pcw_home: OK for 1 KHz
12:17 PM Lcvette: oh this ones no good then?
12:18 PM pcw_home: No fine for 1 KHz (which is fine for step/dir or velocity mode drives)
12:18 PM beachbumpete1: Tom_L naah just being funny. Howsitgoin?
12:19 PM beachbumpete1: Speaking of PC's I am trying to find a good deal on a cheap or used desktop to run my music production software on. I use Reaper and currently run it on my laptop but I am getting tired of having to hook everything up all the time LOL
12:20 PM Lcvette: pcw_home: how do you know which is good for 1khz and which is good for 1khz?
12:20 PM Lcvette: whats the identifier?
12:20 PM Lcvette: 4khz and 1khz
12:21 PM pcw_home: testing is the only way I know (though faster machines usually do better on Preempt-RT)
12:26 PM Lcvette: pcw_home: this is the first little onboard cpu mobo ive come across with m.2 for ssd nvme
12:26 PM Lcvette: it appears its a new model
12:26 PM Lcvette: wonder if its any better than the older ones
12:28 PM Lcvette: seems like a rare feature int he mini ITX's
12:32 PM pink_vampire: where is the code that build the tabs "manual control" and "MDI"?
12:32 PM Lcvette: https://www.gigabyte.com/us/Comparison/Result/2?pids=6222,6494
12:32 PM pink_vampire: i want to merge them to a single tab
12:39 PM Lcvette: pcw_home: do you know the ASRock H97M Pro 4 and G3258 Pentium is? 1khz or 4khz?
12:45 PM jymmm: pink_vampire: Nooooooooooooooo, you can't do that, ever ever ever
12:45 PM pink_vampire: why?
12:46 PM pink_vampire: jymmm: ??
12:46 PM jymmm: pink_vampire because you cut your nails after giving me so much slack over them ;)
12:47 PM pink_vampire: they grow...
12:51 PM pcw_home: Lcvette: H97+G3258 4KHz
01:35 PM skunkworks: pink_vampire: those are different 'modes' in linuxcnc...
01:56 PM Lcvette: pcw_home: \o/ Hurray!! :D
02:08 PM andypugh: pink_vampire: Switching tabs switches modes. Combining them would be awkward. You would probably have to grey-out one or the other set of buttons depending on which were valid for the mode. So the tabs make more sense.
02:15 PM JT-Shop: pink_vampire: you should just build a new GUI it would be simpler that modifying Axis
02:16 PM pink_vampire: JT-Shop: not sure how to do that
02:16 PM pink_vampire: andypugh: yeah, that was the idea
02:18 PM JT-Shop: https://qtpyvcp.kcjengr.com/tutorials/index.html
02:21 PM * JT-Shop puts on his lumberjack hat and goes to cut some rounds...
02:21 PM pink_vampire: JT-Shop: thanks! this is look very informative
02:40 PM gloops: lol, got the mrs installing linux mint after windows 10 went down again, these first time linuxers...
02:41 PM XXCoder: heh dunno windows tend to be damn near immortal for me
02:41 PM XXCoder: even shitty ones like windows me
02:42 PM gloops: this windows has been ok for me, she hasnt had much luck, told her i can get her up and running in 30 minutes, shes installing linux now
02:42 PM pink_vampire: gloops: now get some solidworks on it
02:43 PM gloops: lol pink_vampire she doesnt use anything like that
02:43 PM pink_vampire: *yet
02:44 PM gloops: nah, mainly office crap, powerpoint, word etc
02:44 PM gloops: *facebook*
02:44 PM pink_vampire: libre office is better
02:45 PM pink_vampire: omg facebook
02:45 PM renesis: haha, no
02:45 PM renesis: m$ office actually works now
02:45 PM pink_vampire: what is the best plywood in homedepot / lowes?
02:45 PM renesis: libreoffice has always just been a clone
02:46 PM renesis: and the google crap is pretty neat for collaborative stuff
02:47 PM pink_vampire: is there an open program like the brother p-touch editor
02:48 PM pink_vampire: it work soo grate with my printer, but the files not work if you upgrade the program version
02:48 PM XXCoder: renesis: microsoft office works on linux?
02:49 PM gloops: on wine or VB?
02:50 PM renesis: oh, no then youre prob stuck with libreoffice
02:50 PM renesis: google stuff should work
02:51 PM renesis: it doesnt do as much but if youre just doing basic word processing, slides, and spreadsheets, google stuff is fine
02:51 PM renesis: for multiple people editing same doc, google stuff is awesome
02:52 PM renesis: https://www.howtogeek.com/171565/how-to-install-microsoft-office-on-linux/
02:52 PM renesis: looks like it works with emulator stuff, shrug
02:53 PM XXCoder: wine is not emulator
02:53 PM gloops: libre opens word docs anyway
02:53 PM XXCoder: its literally in name :)
02:53 PM gloops: or saves as doc
02:53 PM renesis: my experiences with libreoffice have been all over the place
02:53 PM XXCoder: what happened to openoffice?
02:54 PM renesis: it died, became libreoffice
02:55 PM XXCoder: fun. ok
02:55 PM renesis: libreoffice is pretty much the same thing, so its pretty much clone of previous gen of ms office
02:55 PM XXCoder: latest ms office I have is 2010 lol
02:55 PM XXCoder: havent used it
02:56 PM XXCoder: *since i upgraded my system 6 years ago
02:56 PM renesis: i just did 4 years of university, so using this shit constantly
02:56 PM renesis: wanted libreoffice to work, but sometimes it misbehaves or gets stuck
02:57 PM renesis: meanwhile, office improved a lot
02:57 PM renesis: i'm not into paying for it but i got it free through school, its way better than 10-20 years ago
02:58 PM renesis: word equation editor is pretty sexy
02:59 PM renesis: its still a bitch to format something like a resume, but i can inkscape stuff like that for free so whatever
02:59 PM renesis: that said, lots of recruiters and resume bots want it word format
02:59 PM XXCoder: i paid for mine lol
02:59 PM renesis: itll populate applications automatically, anything else becomes a horrible mess
02:59 PM XXCoder: forgot how much but much cheaper than non-college would be
03:00 PM XXCoder: i wonder how compitable libreoffice word format is
03:00 PM gloops: haha shes on the net, my peace is restored
03:01 PM renesis: linux last 10 years pretty turnkey
03:02 PM XXCoder: indeed
03:05 PM gloops: thats not bad, i dunno 15-20 minutes, installed, hardly any user input required, up and running on the net, email job lot set up
03:05 PM gloops: free!
03:06 PM renesis: but can it printer?
03:07 PM gloops: sure it can, i didnt have to install any hardware, linux finds, gets drivers, runs most things, these days
03:07 PM XXCoder: gaming gpu stuff is bit annoying. i had decent card that couldnt work 100% due to sucky drivers
03:07 PM XXCoder: decided to buy slightly older but formerly veru high end video card. works awesome]
03:07 PM Rab: I use LibreOffice on Linux in a Windows/Office-centric office. I rarely have problems with document exchange except that the fonts tend to be inconsistent between platforms.
03:08 PM gloops: ive not run games, no problem with 3d cad stuff though
03:08 PM XXCoder: whats you use for cam?
03:08 PM XXCoder: that one is nearly all windows or sucky
03:09 PM Rab: But if you need your docs pixel-accurate, e.g. typesetting for print, Word's kind of a turkey anyway.
03:09 PM gloops: blender, aspire (runs on wine), sketchup works on linux
03:09 PM gloops: not had fusion work on it though
03:10 PM Rab: Sketchup post-Trimble buyout is Windows-only, I thought...haven't tried in Wine
03:10 PM gloops: you can download the old versions, i had it working fine
03:11 PM XXCoder: can download microsoft fonts so looks match
03:11 PM XXCoder: in fact there tend to be microsoft font licensed packages in repos
03:11 PM andypugh: skunkworks: has Fusion360 running on Linux (not sure if Wine or a VM)
03:12 PM gloops: lol, on the toshiba laptop touchpad scroll never worked on windows 10, shes just beamed and said - yes! ive got my scroll
03:13 PM XXCoder: geez lol
03:13 PM gloops: 2 finger scroll or edge scroll? both work - im not savvy with touch typing
03:16 PM roycroft: gloops: are you about?
03:17 PM gloops: roycroft i think i am yes
03:17 PM XXCoder: probably not
03:17 PM gloops: about what?
03:17 PM gloops: 5 11.5
03:18 PM gloops: 13.5 stones?
03:18 PM andypugh: I got a bit more serious with the Faro arm calibrator. https://photos.app.goo.gl/ECet2cJynDyd9Ra66
03:18 PM roycroft: i just want to tell you, especially after our conversation of yesterday, that while i disagree with you almost completely on virtually every aspect of brexit, i sincerely wish you and the british people all the best, and i hope that things don't go nearly as badly as i think they will
03:18 PM roycroft: i felt things were left on a rather sour note yesterday, and that was not my intent
03:19 PM gloops: roycroft ive never thought of you who would wish bad things on anyone (who didnt deserve it) and thanks, im sure we'll get by somehow lol
03:20 PM XXCoder: andypugh: whts it do?
03:20 PM XXCoder: looks like adjusting 4th axis or something
03:20 PM roycroft: i don't - i can disagree with someone without disliking the person
03:20 PM XXCoder: indeed
03:20 PM XXCoder: roy i know me and gloops argued a lot sometimes lol
03:21 PM roycroft: and that's all i have to say about that :)
03:22 PM XXCoder: erm is that light meter andy heh
03:24 PM Rab: Anybody have opinions on Atlas 10" lathe for a home shop? One's on craigslist in really nice shape, but it looks kinda lightweight.
03:24 PM roycroft: a lot of nice parts have been made on that lathe, rab
03:24 PM roycroft: make sure it's not worn out or abused before purchasing it though
03:25 PM andypugh: XXCoder: I have a Faro arm, but need to calibrate it to convert voltage (counts) to angle. I have a very accurate Megatorque servo with a super-high count encoder that I am basically using as a protractor.
03:25 PM XXCoder: nice!
03:25 PM roycroft: and don't pay very much for it
03:25 PM XXCoder: normally that'd be insane overkill budget wise for it but since you got it cheap...
03:25 PM Rab: roycroft, https://austin.craigslist.org/tls/d/austin-atlas-lathe/6845001612.html
03:26 PM roycroft: especially if it doesn't have a quick change gearobx
03:26 PM Rab: I suppose that counts as very much, but it's rare to see a lathe in any kind of decent shape <$2K around here.
03:26 PM andypugh: That’s crazy money for an Atlas
03:26 PM andypugh: Though it does have the Norton box
03:27 PM roycroft: that one looks clean
03:27 PM roycroft: but it may be just cleaned up
03:27 PM roycroft: it's worth 1/2 that much
03:28 PM roycroft: i got my 12x36 for $700, after watching cl posts daily for a couple years
03:28 PM Rab: It's only $550 more than this one! https://sanantonio.craigslist.org/hvo/d/leonard-south-bend-lathe/6831185748.html
03:28 PM roycroft: cheaper lathes are available, but they get snatched up very quickly
03:28 PM andypugh: Have you tried eBay? Or Facebook ads?
03:28 PM roycroft: in those two years i was the second caller countless times
03:29 PM andypugh: Facebook seems to have more clueless vendors :-)
03:29 PM roycroft: i'd say that from the pictures that lathe looks potentially good
03:29 PM Loetmichel: BTW: i had a meeting today with a customer about a 2u Server enclosure. They were complaining that the new box has a lot more screws in it than the old one... $me:"ahem, the old one had even more screws in the bottom than the new one!" (I know, i designed and built that, too!)... them:" no way, it only had 3 on each side, none at the bottom, i am sure of it. There it is, look yourself!"...
03:29 PM Loetmichel: So i lifted it: Lo and behold, 24 empty screwholes. $me: "so much for 'RF shielded'." Customer: "Ups!" :-)
03:29 PM roycroft: but again, the asking price is 2x what it's worth
03:30 PM Rab: andypugh, I hear Facebook Marketplace is on fire, but I don't have an account.
03:30 PM Rab: roycroft, noted, thanks!
03:30 PM roycroft: if it came with a 4 jaw it would be more interesting
03:31 PM * roycroft would rather eat rusty nails than go on facebook
03:31 PM Rab: Yeah, 4 jaw chuck and QCTP would be first additions.
03:31 PM roycroft: the 4 jaw chuck itself is no big deal
03:31 PM roycroft: but you would have to make a mount for it
03:31 PM roycroft: and that lathe may have some odd thread size on the spindle
03:32 PM roycroft: you're not going to just go buy a chuck that you can screw on to it
03:32 PM roycroft: so be prepared for that
03:32 PM roycroft: it's a good project to test your turning skills :)
03:33 PM roycroft: that's why it's nice if it comes with one - that bit of work is already done for you
03:34 PM roycroft: it's nice that it comes with a steady rest and follow rest
03:34 PM roycroft: you don't have to track those down
03:35 PM roycroft: the other nice thing is that the 10" atlas is a rather ubiquitous lathe, so if you need parts they should not be difficult to find
03:35 PM andypugh: I had to make my own steady rest for my lathe. Because of the problem alluded to above
03:35 PM roycroft: mine did not come with either
03:36 PM roycroft: and it's not a very common lathe
03:36 PM roycroft: but it's very similar to a lot of other 12x36 lathes
03:36 PM andypugh: Nice lathe here for a decent price. Needs a clean: https://www.ebay.co.uk/itm/Holbrook-Lathe-used/333124790959
03:36 PM roycroft: i was able to find an old grizzly model that was very similar, and bought the steady rest and follow rest from grizzly's spare parts department
03:37 PM roycroft: they fit fine - i had to modify the mounts, but otherwise they're just fine
03:38 PM roycroft: i don't have room in my shop for a medium size lathe like that
03:38 PM roycroft: i have to stick with a smallish one
03:38 PM roycroft: but 12x36 is a very useful size
03:39 PM roycroft: rab: make sure the atlas has the 127 tooth gear, if it needs it
03:39 PM roycroft: that gear is often missing on old lathes, and you can't cut metric threads without it
03:40 PM roycroft: and if you're going to say you will never need to cut a metric thread, minutes after those words come out of your mouth you'll have a need to do so :)
03:42 PM andypugh: That’s the excuse to convert to CNC, or at least electronic leadscrew
03:43 PM roycroft: and speaking of cutting threads
03:43 PM roycroft: i've been thinking more about this round thread that i might want to try
03:44 PM roycroft: and the more i think about it the more i think that cutting a standard v-groove thread first and then using the form tool to reshape it is the best approach
03:45 PM roycroft: i have a qctp, and as long as i set the height of the two tools exactly the same, i should be able to just pull the single point tool of, swap the round tool in, and keep cutting, right?
03:48 PM andypugh: Yes
03:48 PM gregcnc: round thread for what? If you don't have problems making the initial cuts with the round form, why bother changing tools?
03:48 PM andypugh: Do-able even if they are not in the same place
03:48 PM andypugh: just offset
03:48 PM roycroft: i need to make some torsion springs
03:49 PM roycroft: and when i use a cylinder as a mandrel and wrap the wire around it it does not lay very neatly
03:49 PM roycroft: i thought that if i cut a round thread in the mandrel it would hold the coils in place better
03:49 PM andypugh: Use the lathe and leadscrew as a guide
03:49 PM roycroft: so this is nothing that needs to be high precision at all
03:49 PM gregcnc: I don't think that will help at all
03:50 PM andypugh: (run the wire through a hole in the toolpost)
03:50 PM roycroft: my lathe does not turn slowly enough for me to even begin to feel comfortable doing that
03:50 PM roycroft: i only need five turns
03:51 PM Rab: roycroft, why do you need a rounded profile? Won't a conventional thread support the wire adequately with two points of contact?
03:51 PM roycroft: it might, rab
03:51 PM roycroft: i thought of that
03:52 PM roycroft: but by the time i thought of that i had already thought about cutting a round thread
03:52 PM roycroft: and now i want to see if i can do it
03:52 PM roycroft: i have this bad habit of sometimes trying things just to see if i can do them
03:52 PM gregcnc: what is the actual problem making the spring?
03:52 PM roycroft: the coils do not lay neatly next to each other
03:53 PM roycroft: when i try to wrap the wire around the mandrel they spread apart
03:53 PM Rab: Having contemplated the issue I recognize the imperative, just not the utility.
03:53 PM gregcnc: feed is wrong
03:53 PM roycroft: i'm doing it by hand
03:53 PM gregcnc: feed is still wrong
03:53 PM roycroft: i have a cylinder welded to a steel plate - the cylinder is vertical
03:53 PM roycroft: there's a clamp at the bottom to hold the end of the wire in place
03:54 PM roycroft: i walk around the jig making the coils
03:54 PM roycroft: this is 0.210" diameter wire, btw
03:54 PM roycroft: not huge, but still fairly stiff and not easy to bend
03:55 PM roycroft: i've seen folks do this by clamping guides to the mandrel and moving the guides up every turn
03:55 PM roycroft: but that seems like a lot of extra effort
03:55 PM roycroft: so i thought that maybe if the manrel had grooves in it they would help guide the wire
03:55 PM Loetmichel: ehm .. thats 5,4mm wire. you can bend that between fingers and thumb of a single hand
03:55 PM roycroft: music wire?
03:56 PM roycroft: your fingers must be a lot stronger than mine
03:56 PM roycroft: annealed copper wire, mayhap
03:56 PM gregcnc: it has to do with the position of the guide in relation to where teh bend is occuring
03:56 PM JT-Shop: do you pull down while winding assuming winding from bottom up
03:56 PM Loetmichel: steel wire
03:56 PM Loetmichel: ok, music wire is a bit harder ;)
03:56 PM roycroft: at lest horizontal, jt-shop
03:56 PM roycroft: certainly not up
03:56 PM roycroft: i can't pull down very much, as there's a table directly below
03:57 PM JT-Shop: try pulling down and make it rub on the previous coil
03:57 PM roycroft: i just need a wee bit of help keeping it even
03:57 PM Loetmichel: and yes, been there done that bent 6mm silver steel rod by single hand
03:57 PM Loetmichel: its not that hard
03:57 PM andypugh: This is how I make springs (1/4” wire) https://www.youtube.com/watch?v=thtDRjgbxRE
03:57 PM gregcnc: loetmichel is superhuman and none of us mortals can match him
03:57 PM roycroft: and i am old and feeble
03:57 PM roycroft: and i don't care
03:58 PM roycroft: i've turned to the work smart, not hard school of thought :)
03:58 PM andypugh: Loetmichel: Pah! my wire was 6.35mm!
03:58 PM roycroft: except while i think i'm smart, i'm not always that clever
03:59 PM roycroft: teh youtube denies me, andupugh :(
03:59 PM roycroft: hmm
03:59 PM andypugh: Odd, it works for me and seems a reasonable URL
03:59 PM roycroft: it must be a georestriction, which is odd
03:59 PM roycroft: i just vpn'ed into the uk and now i can watch it
03:59 PM andypugh: Try https://youtu.be/thtDRjgbxRE
04:00 PM Loetmichel: gregcnc: nonsense. i just work with my hands
04:00 PM Loetmichel: and i AM old, too ;)
04:01 PM roycroft: i'm assuming loetmichel is closely related to hagrid
04:01 PM roycroft: at least from the same clan
04:01 PM Loetmichel: andypugh: spring steel?
04:01 PM Loetmichel: roycroft: missing about 2' in height and widht for that ;)
04:02 PM jthornton: andypugh: what was that spring for?
04:02 PM jthornton: and that is a pretty slow spindle
04:02 PM roycroft: doing it on the lathe would be great
04:02 PM roycroft: but as i said, my lathe does not go that slowly
04:02 PM roycroft: 60rpm is my minimum speed, and i would not feel comfortable doing it that fast
04:02 PM gregcnc: no back gear?
04:02 PM roycroft: that's with the back gear enaged
04:02 PM gregcnc: no VFD?
04:03 PM andypugh: That is 45rpm gear, lowered by VFD
04:03 PM andypugh: It can do 1rpm
04:03 PM roycroft: whenever i put a 3 phase motor and vfd on it i'll slow it down to 25rpm or so
04:03 PM roycroft: but right now all i have is a single phase motor
04:03 PM roycroft: and 60rpm
04:03 PM andypugh: Yes, spring steel. The saddle suspension springs for Ner-a-Car
04:03 PM Loetmichel: nice
04:03 PM andypugh: Right, work meeting ! (With Australia, hence the lateness)
04:04 PM roycroft: my lathe can cut threads at 4.5tpi, which is almost perfect for the wire i'm using
04:04 PM roycroft: it's just the speed thing that's a problem
04:04 PM Loetmichel: roycroft: you cant bend SPRING steel by hand (of that size). but mild steel should be doable
04:04 PM Loetmichel: thats what i meant above
04:05 PM gregcnc: http://www.deansphotographica.com/machining/projects/springs/springs.html
04:06 PM gregcnc: read the text below the 6th pic
04:08 PM roycroft: making a handwheel for my lathe is on my list of projects to do when i get around to it
04:08 PM gregcnc: about the angle
04:08 PM roycroft: i could probably turn it by hand by using the chuck key
04:08 PM roycroft: yes, i read that part too
04:09 PM roycroft: and i can't pull it back like that with my current jig
04:09 PM roycroft: but i can make a new jig
04:10 PM roycroft: i've been told too that i should anneal the music wire, make the springs, and then heat treat them after
04:10 PM roycroft: i'd rather not mess around with that
04:10 PM roycroft: and i can bend the wire
04:10 PM roycroft: just not as neatly as i'd like, currently
04:11 PM gregcnc: I think some stress relief is normal procedure
04:11 PM roycroft: that i don't mind
04:12 PM roycroft: that does not require fairly precise heat control, and is low temperature
04:12 PM roycroft: but rehardening and tempering is a different matter
04:13 PM roycroft: and i don't even understand how to do that properly with spring steel
04:13 PM roycroft: although i'm sure it's farily straightforward to do
04:14 PM * roycroft will give redesigning the jig to allow him to pull back better a think
05:26 PM Deejay: gn8
06:03 PM Tom_L: andypugh thanks for the config help yesterday
06:04 PM andypugh: Working now?
06:04 PM Tom_L: haven't cut anything but i did start that program and watch it a bit
06:04 PM Tom_L: seems ok
06:05 PM andypugh: roycroft: You absolutely should _not_ temper and heat-treat music wire.
06:05 PM Tom_L: gonna try cutting some steel once i work out the program. dunno if that little mill will like it or not
06:06 PM andypugh: The properties of music wire come from the cold-drawing process, you can never get them back with heat-treatment.
06:06 PM andypugh: (This is pretty much my specialist subject, I spent 2 years dong post-doctoral research on enhanced cold-drawn spring steels)
06:24 PM jthornton: andypugh: that's good information to know about spring steel
06:25 PM -!- #linuxcnc mode set to +v by ChanServ
06:25 PM andypugh: Vehicle-suspension sized springs (especially leaf springs) are made soft then heat-treated.
06:26 PM andypugh: But anything sold as music wire is cold-drawn to harden it.
06:27 PM Tom_L: it does make good springs
06:29 PM Tom_L: jthornton, looks like buildbot is back
06:30 PM Tom_L: i got a short bar of 'mild' steel at the scrap. gonna see how it machines
06:35 PM jthornton: yea, seb got it going again
06:35 PM Tom_L: hope that request i triggered was what you wanted
06:48 PM jthornton: well it was broken so that didn't work but that was the syntax I was looking for
07:16 PM roycroft: i am glad the channel is quiet, as i don't log irc and have a small scroll buffer
07:16 PM roycroft: i'd have missed andypugh's sage words had there been more activity here while i was afk :)
07:44 PM Tom_L: jthornton, what rpm would you run a .250" cutter in steel?
07:48 PM Tom_L: 2000 is 130 sfm which seems a little high maybe but i tried it and seemed to do ok there
09:17 PM -!- #linuxcnc mode set to +v by ChanServ
10:46 PM Elmo40: yes, 2,000 is a little high
10:46 PM Elmo40: carbide or hss?
10:47 PM Elmo40: how many flute?
10:47 PM Elmo40: how deep a cut?
10:47 PM Elmo40: 'steel' ? what grade? temper? how rigid is the setup?
10:47 PM Elmo40: and on and on and on...
10:47 PM Elmo40: coolant or dry?
10:50 PM Tom_L: i know
10:51 PM Tom_L: more than likely carbide 4 flute
10:51 PM Tom_L: dunno the steel, mild
10:51 PM Elmo40: then it sounds about right.
10:51 PM Tom_L: the test i ran manually sounded ok
10:51 PM Elmo40: i'd go 2200 or more with carbide and mild steel.
10:51 PM Tom_L: depends what i can find
10:52 PM Tom_L: right now i'm modifying the program from aluminum to cut steel
10:52 PM Tom_L: and the bar is a little smaller so i'm adjusting things
10:54 PM Elmo40: try 1/3 everything to start off with.
10:54 PM Elmo40: then go up from there
10:54 PM Tom_L: taking smaller cuts
10:54 PM Elmo40: 1/4 is a small tool. doesn't handle much as it is
10:54 PM Tom_L: i wanted 12L14 but couldn't find any local
10:55 PM Tom_L: it's a small mill too
