12:43 AM miss0r: Goodmorning.
12:47 AM miss0r: This is just one of those days where I wish I had a bridgeport or simular. Last night I started noticing issues with the head of my mill nodding(rotated in the Y-Z plane).. But theres no way to ajust this on my mill. I either need to scrape the mating surfaces of the vertical head & the ram or see if something else is up
01:00 AM Deejay: moin
01:08 AM miss0r: morning
02:15 AM Loetmichel: miss0r: like they use to say over in #reprap: your hobby isnt 3dprinting, its 3dprinters ;)
02:15 AM Loetmichel: (or in your case: its not milling, its mills) ;)
02:15 AM miss0r: hehe
02:15 AM miss0r: hobby/livelyhood :)
02:16 AM Loetmichel: same thing ;)
02:16 AM Loetmichel: (ideally)
02:18 AM miss0r: it is...
02:18 AM miss0r: I am getting all sorts of off measurements on this mill at the moment.
02:18 AM Loetmichel: or as a friend of mine said a few decades ago: you are only a real hobby machinist if you catch yourself making a fixture to hold a part on the mill thats needed to make a part for a bending brake to make a part thats pourpose you have long forgotten ;)
02:18 AM miss0r: haha yeah
02:23 AM * Loetmichel just designed a battery lid for a cable tester and is just printing it. Sometimes a 3dprinter at the company is useful... considering that that cable tester costs a few 100 bucks and isnt fit to use without the lid... (and of course there are no spare parts aviable) ;)
02:54 AM Loetmichel: hihi, sometimes a 3d-printer is really useful... not perfect (measured the length wrong by a mm) but good enough: http://www.cyrom.org/palbum/main.php?g2_itemId=17544&g2_imageViewsIndex=1
03:58 AM Valen: mmmm gantry squaring home works https://www.youtube.com/watch?v=zePeCzJes4Q
05:00 AM Tom_L: morning
06:04 AM jthornton: morning
06:09 AM miss0r: ahh. pulling stuff straight off the mill and it is right on size (atleast within 0.01 mm)
07:01 AM jthornton: make any progress on the shaper?
07:04 AM XXCoder: yo
07:13 AM miss0r: jthornton: At the moment I am hollowing out the sides of it, to a) allot for screws to be inserted and B) lighten it up a bit.
08:06 AM miss0r: jthornton: This is the status as of now? https://imgur.com/a/TAIwyQd
08:07 AM miss0r: I have to do the same to the other side, Drill and tap some oil nibbles in there and do a general debur. Then that part is done
08:37 AM miss0r: jthornton: And this is a quick test setup with iso taper, gears & the back bearing mounted temporarily https://imgur.com/a/pJYMotn
08:39 AM jthornton: looking good!
08:46 AM miss0r: Thanks. Its a damn mess. and I can't wait to be done working on cast iron
08:46 AM Elmo40: dusty?
08:46 AM miss0r: yeah
08:46 AM miss0r: graphite tust
08:46 AM miss0r: dust*
08:46 AM miss0r: If I sneeze I might break a floor tile
08:47 AM miss0r: thats it for the day. Now to be a family man. Later I will be back here for the night work :D
08:52 AM jthornton: see you later
08:53 AM Loetmichel: miss0r: ah, reminds me of old times in the model shop... you could tell by the colour of the sneeze in the evening if i had milled FR4 or carbon fibre boards all day :-)
09:06 AM Elmo40: i used to work in an iron foundry. we cut sprues from the moulds.
09:06 AM Elmo40: lots-o-graphite!
09:21 AM Loetmichel: Elmo40_ i once got a PC from a foundry
09:21 AM Loetmichel: "CRT is way to dark and system is acting up occasionally"
09:22 AM Loetmichel: thoght: wow, fancy anthracite casing (PCs back then were usually beige)
09:22 AM Loetmichel: ... opened the CPU box: full to the brim with slag.
09:22 AM Loetmichel: cleaned it out, replaced the fans because they stalled and burned out: works again.
09:23 AM Loetmichel: then went on to clean the outside: "ah, it actually WAS beige!"
09:23 AM Loetmichel: ... and the CRT wasnt dead either, just so dirty that no light came thru the glass ;)
09:56 AM Valen: Thought I had fried a channel of my 7i76 with ESD, turns out they work better with the plug in all the way
10:12 AM Valen: I seem to recall a setup that would let you jog off a limit switch but only jog in the off limit switch direction. at present once you hit override limit you can jog in any direction (further into the limit say)
10:16 AM Valen: Does such a thing exist or am I remembering things I want rather than things that are?
10:18 AM Loetmichel: *MUHAHAHAHA* coworker just wanted to bend an prenotched U-bracket 30cm*20cm*20cm made of 3mm alu in the bending brake... turned out to small because the bending brake slipped... $me: "give the second blank please"... took it, put the prenotch "bends" on the corner of the desk, uilized a bit of body weight: two perfect 90° angles... and fits perfect... his look at me... priceless ;)
10:37 AM tommylight: ???
10:37 AM tommylight: YAY registered finaly !
10:41 AM tommylight: all asleep ?
11:02 AM jthornton: cutting firewood...
11:10 AM drdoc: Loetmichel: I used to transcribe obsolete computer media on the side
11:11 AM drdoc: I got a set of 8" floppies in... 2005? that were the boot & program disks for a crankshaft balancer
11:12 AM CaptTactful: hello world?
11:12 AM drdoc: that computer had been sitting in an auto shop for nearly 20 years
11:13 AM drdoc: CaptTactful: it was a menu-driven CNC program
11:13 AM drdoc: anyhow, those flopy disks had started throwing errors, so they asked me to make copies
11:14 AM drdoc: I ended up flying out to Alabama to do it, because I refused to put them in my drives
11:15 AM drdoc: Pretty sure the errors were due to the oil and coolant soaking through the jacket
11:16 AM CaptTactful: hi drdoc
11:16 AM CaptTactful: may i ask you a stepconfig question?
11:17 AM drdoc: you may, but I'm a complete noob
11:18 AM drdoc: I know a little about CNC from wotking in machine shops, and a little about steppers from running a 3D printer
11:18 AM drdoc: and obviously, nothing at all about typing.
11:19 AM drdoc: but I've never run a mill with steppers
11:21 AM CaptTactful: thank you. I am tweaking my config file for lcnc.
11:21 AM CaptTactful: i have .9Deg motors
11:22 AM drdoc: nice
11:22 AM CaptTactful: which is 400 steps per rev
11:22 AM drdoc: right
11:22 AM CaptTactful: microstepping field is set at 8
11:23 AM CaptTactful: which it should b
11:23 AM CaptTactful: i think
11:23 AM drdoc: well, you're running lead screws?
11:23 AM CaptTactful: but, getting double the travel at least
11:23 AM CaptTactful: neg. belts
11:23 AM drdoc: 1:1?
11:23 AM CaptTactful: yes
11:24 AM drdoc: so, 3200 steps per rev
11:24 AM CaptTactful: not 2224?
11:24 AM CaptTactful: 1.8Deg is 1112
11:25 AM gregcnc: http://linuxcnc.org/docs/devel/html/config/stepper-quickstart.html
11:25 AM CaptTactful: at least, thats what documentation tells me.
11:25 AM gregcnc: at the bottom
11:26 AM CaptTactful: But, I have an extremely difficult time pulling info from docs.
11:26 AM CaptTactful: ok.
11:26 AM CaptTactful: ill try
11:26 AM gregcnc: what is scale in in stepconf?
11:27 AM CaptTactful: inches
11:27 AM gregcnc: axis scale in step/in
11:27 AM drdoc: it's 360/.9, times the uStep setting, then divide that by the tooth count * pitch of the drive pulley
11:28 AM CaptTactful: dang. i dont have pulley access on this machine. zenbot 1624
11:28 AM drdoc: ah
11:29 AM CaptTactful: so, 360Degs / .9 = 400 spr
11:29 AM CaptTactful: then 400 spr x microstepps?
11:29 AM drdoc: well, the docs ought to tell you steps per inch or steps per millimeter, at a given microstep setting
11:30 AM drdoc: yes, 400 full steps * microstep
11:30 AM CaptTactful: evrything they have now is 1.8Deg motors
11:30 AM CaptTactful: so docs r for that
11:31 AM drdoc: the number will just double for .9deg
11:32 AM drdoc: lead screw calculation is a lot easier to visualize than belts
11:33 AM CaptTactful: excerpt from manual regarding .9Deg motors: The manual for the Zenbot 1216 states that "the drive pulley diameter on this machine is .458 inches. The circumference of the drive pulley is 1.439. This means that the motor rotates .695 turns per inch (1/1.439). The stepper motors on this machine are .9 degree per step motor, which means that there are 400 steps per revolution. Now you just need to know the micro-step settings on
11:33 AM CaptTactful: your drivers. The formula for calculating the steps per inch is .695 x 400 x micro-steps/step. For a 1/8 micro-step driver, the formula would be .695 x 400 x 8 = 2224 steps per inch."
11:33 AM drdoc: there you go
11:34 AM CaptTactful: is the problem that i have a 1:1 microstepping instead of 1:8?
11:34 AM drdoc: could be
11:35 AM gregcnc: math doesn't lie. but the numbers have to be correct
11:35 AM drdoc: that
11:35 AM CaptTactful: .9Deg into 360 is 400 steps per rev.
11:35 AM drdoc: if the driver's set to 1:1 and the program's set to 1:8, you'll be moving 8 inches instead of the intended 1
11:36 AM CaptTactful: 400 x 8 microsteps is 3200
11:36 AM CaptTactful: 3200x.695 = 2224 totalsteps
11:36 AM drdoc: CaptTactful: yup
11:36 AM CaptTactful: not moving 8 inches though
11:36 AM gregcnc: verify pulley ratio
11:36 AM CaptTactful: approx 1 inch for each 1/2 inch run command
11:36 AM drdoc: IF your stepper drivers are really set to 1:8 microsteps
11:37 AM gregcnc: are you certain the motors are 0.9°?
11:37 AM CaptTactful: spoke to Shaun at Zenbot
11:37 AM gregcnc: sure, but what's in the machine?
11:37 AM CaptTactful: he remembered the .9 Deg motors
11:37 AM CaptTactful: the labels say this as well
11:38 AM gregcnc: ok
11:38 AM gregcnc: plenty of butchered machines out there
11:38 AM drdoc: do you have jog controls?
11:38 AM drdoc: active, I mean
11:39 AM drdoc: If I'm not sure of my settings, I print/cut a square as big as my build envelope allows
11:39 AM CaptTactful: i believe so. when the program is running or test run inside config setup?
11:39 AM drdoc: either
11:39 AM CaptTactful: noticed the issue when doing an axis test run inside satep configuration
11:40 AM drdoc: I have a .nc that grooves a 14x14 square on my waste board
11:40 AM drdoc: that lets me check scale and square
11:41 AM CaptTactful: yup. tried it again.
11:41 AM drdoc: if I were having the problem you are, I'd program 7x7
11:41 AM drdoc: :-)
11:41 AM CaptTactful: moves about 1 in when commanded 1/2in
11:41 AM CaptTactful: 7x7?
11:41 AM drdoc: My machine has 15" of X and Y
11:42 AM drdoc: if it's moving 2 to one and I programed to cut a 14" square, I'll hit the stops
11:42 AM gregcnc: count pulley teeth, measure lead screw pitch, you can't go wrong
11:42 AM drdoc: gregcnc: it sounds like that's a V-belt
11:43 AM gregcnc: is that a joke?
11:43 AM drdoc: no
11:44 AM CaptTactful: v-belt like afor a pully?
11:44 AM CaptTactful: i have flat multi tooth belts
11:44 AM drdoc: if it were a toothed pulley, wouldn't the docs give tooth count & pitch instead of circumference?
11:44 AM gregcnc: timing belts
11:44 AM drdoc: OK
11:45 AM drdoc: I have no idea exactly how big the timing pulleys are on my 3D printer
11:45 AM drdoc: 2mm pitch, 60 teeth, done
11:45 AM drdoc: 120mm travel per rev
11:46 AM drdoc: anyhow
11:47 AM drdoc: when all else fails, I tell the machine to do what I want, in a way that allows accurate measurement of what it actually does
11:47 AM CaptTactful: i would like to be as confidant in this as you are. it would probably help alot.
11:47 AM CaptTactful: i fear hurting the mill
11:48 AM gregcnc: counting and measuring is the answer, those are things you can be confident in
11:48 AM drdoc: or, you know
11:48 AM CaptTactful: thank you, ill give it another go.
11:48 AM drdoc: find the motor label
11:49 AM CaptTactful: have it
11:49 AM CaptTactful: 57BYGH603-4
11:49 AM drdoc: that should give you a definite answer to the step angle
11:49 AM CaptTactful: 0.9Deg
11:49 AM CaptTactful: 3A
11:49 AM drdoc: Ok
11:49 AM CaptTactful: 3.6V
11:50 AM drdoc: how do you set the microstep ratio on your drivers?
11:50 AM CaptTactful: driver is easy cnc mechatronis 3-axis driver board.
11:50 AM CaptTactful: so, factory set for my motors
11:51 AM drdoc: meaning you should check that
11:51 AM gregcnc: was factory set, maybe
11:52 AM CaptTactful: gotcha
11:52 AM CaptTactful: trust, but, verify
11:52 AM CaptTactful: gotit
11:52 AM drdoc: never trust
11:52 AM drdoc: I built my printer, and am building my router
11:53 AM gregcnc: Ah no lead screw so pulley diameter is relevant
11:53 AM drdoc: and even at that, if it doesn't act like it should, I never assume I did any step correctly
11:54 AM drdoc: aw, yeah
11:55 AM drdoc: I'm trying to get some un-horrible latency numbers on an old Dell
11:55 AM drdoc: it's got one of the SMI'd chipsets
11:55 AM gregcnc: how old?
11:55 AM CaptTactful: im running an older optiplex gx620 with addon parallelports
11:55 AM drdoc: Dimension 8400, LGA775 Pentium 4
11:55 AM CaptHindsight: CNC machines usually use timing belts so pulley ratios are easy enough, you just count the teeth
11:55 AM CaptTactful: works very nice with latency
11:56 AM drdoc: CaptHindsight: thank you
11:56 AM CaptTactful: yah, i just dont have access to the teeth without dissasembling the machine
11:56 AM CaptHindsight: this works as long as you have matching pitch on both the pulleys and belts
11:56 AM drdoc: I'm still wondering why the docs give figures based on diameter
11:56 AM gregcnc: because it's like an inkjet printer
11:56 AM drdoc: ?
11:57 AM CaptHindsight: they should match unless some clueless person has had at it
11:57 AM drdoc: heh
11:57 AM drdoc: If they don't match, it should be very obvious very soon
11:58 AM drdoc: shake, rattle & roll
11:58 AM CaptHindsight: if you have acess to the docs for the pulleys then you can go by diameter
11:58 AM drdoc: yes
11:58 AM drdoc: CaptTactful quoted them a bit ago
11:59 AM CaptHindsight: measuring the OD of a pulley with odd numbers of teeth can be challenging
11:59 AM drdoc: well, and the pitch diameter isn't the OD
11:59 AM CaptHindsight: doesn't matter
12:00 PM drdoc: that's why I prefer pitch & tooth count
12:00 PM drdoc: over diameter
12:00 PM JT-Shop: well that's one project done... 999 to go
12:00 PM gregcnc: zenobto says 3mm belts
12:02 PM drdoc: man, tabbed browsers are a mixed blessing for an ADHD person
12:02 PM drdoc: I know I had the SMI module page up, in here somewhere
12:03 PM gregcnc: in FF if you start typing smi it will bring up recents and open tabs
12:04 PM drdoc: yeah
12:05 PM drdoc: unless I shop at smile.amazon.com, and have been watching blacksmith youtubes....
12:07 PM gregcnc: i think the pulley are 12T
12:08 PM gregcnc: my brain is still so clogged all week long this cold
12:09 PM drdoc: Is the 10.04 version what I want on this old P4?
12:09 PM drdoc: single-core, ICH6 chipset
12:14 PM CaptTactful: ok, Spoke to Zenbot Shaun, He'll send me the proper config file and info.
12:15 PM CaptTactful: my dell is an optiplex gx620 with a P4 HT and 4Gb RAM running Wheezy 2.8
12:15 PM CaptTactful: and its doing quite nicely overall
12:15 PM CaptTactful: latency is great
12:17 PM drdoc: cool
12:17 PM CaptTactful: I have I have an OLD Dell D505 laptop which others use and I found it to work well in the past. I upgraded because its easier to utilize pcie slot parallel port additions
12:18 PM CaptTactful: so, plenty of inputs for whatever! nice!
12:18 PM drdoc: I think yours is basically the same system I'm putting together - an Optiplex 320
12:18 PM CaptTactful: my first was an optiplex 320
12:18 PM CaptTactful: no issues with it either.
12:19 PM drdoc: Our ex-roommate abandoned a bunch of Dells when he moved out
12:19 PM CaptTactful: I wonder if its something peculiar to dells as many cncers use dells
12:19 PM CaptTactful: he must use Mach3
12:19 PM CaptTactful: pity
12:19 PM drdoc: an XPS 400, a Dimension 2400, a 3000 and this 8400, and the Optiplex 320
12:19 PM drdoc: he used Excel, mostly
12:20 PM drdoc: contract sysadmin for a bunch of attorneys
12:20 PM drdoc: the Optiplex has a really awful Celeron in it
12:20 PM CaptTactful: sorry, bad joke
12:21 PM drdoc: I know
12:21 PM gregcnc: i have a mchien running an ancient gx150?
12:21 PM CaptTactful: I dont think celeron is great for cnc
12:21 PM CaptTactful: but then again, its noy processing power needed, its latency, so...
12:21 PM drdoc: no, the latency numbers were mid-6 figures
12:22 PM CaptTactful: no way! mine eventually moved on to mooring my boat in shallow waters
12:22 PM drdoc: oddly enough, of all the systems I have available, the one tht's posting the best numbers is a little Nexcom shoebox
12:22 PM CaptTactful: really? never seen a Nexcom
12:23 PM drdoc: the box is an EBS1575, but it's easier to find it by the board number
12:23 PM drdoc: EBC575
12:23 PM drdoc: socket 478 P4, slow-ass DDR RAM, no SATA, and onboard video
12:24 PM drdoc: but it's an industrial board and the BIOS seems designed for realtime work
12:28 PM CaptTactful: sounds like a work horse
12:28 PM CaptTactful: gotta beg off for now guys. Thank you all for your input. Im grateful for it.
12:37 PM SpeedEvil: https://www.youtube.com/watch?v=-aDOpyUmfL4 - SpaceX getting ready to lift one half on top of the other.
12:37 PM SpeedEvil: 35mup
12:41 PM drdoc: yeah, that's all a hoax
12:41 PM drdoc: I know a guy who's an absolute Flat-Earther
12:41 PM drdoc: talking to him is like taking LSD
12:45 PM SpeedEvil: I wouldn't like to be the diudes in the middle
12:46 PM CaptHindsight: reminds me of the Science channel
12:47 PM CaptHindsight: if anything goes wrong here the rocket could come crashing down on the multimillion dollar program
12:48 PM SpeedEvil: It is likely the total cost of stuff is in the $20M range
12:48 PM CaptHindsight: but if anything goes wrong .....
12:49 PM SpeedEvil: They only started making this some 3 months ago
12:49 PM CaptHindsight: with nerves of steel the crane operator positions the assembly withing fractions of an inch several feet off the ground
12:50 PM SpeedEvil: I assume there are ropes that are invisible
12:51 PM CaptHindsight: billy booby joe has done it! the section is in place and the space race can go on another day
12:52 PM CaptHindsight: on mistake and the assembly could have been a mess of twisted aluminum foil
12:52 PM CaptHindsight: on/one
12:52 PM gregcnc: stainless foil?
12:52 PM SpeedEvil: stainless foil
12:53 PM CaptHindsight: good thing billy bobby joe one had two drinks this morning, another disaster has been averted
12:53 PM CaptHindsight: one/only
12:55 PM CaptHindsight: huh, it's like the crane operator knew where he had to place that thing
12:57 PM CaptHindsight: $10 says it lines up and they bolt it together
01:01 PM CaptHindsight: wind 12.75 mph
01:01 PM CaptHindsight: if the wind changes speed or direction "the rocket could come crashing down on the multimillion dollar program"
01:11 PM JT-Shop: hmm the 021 is 22 years old today
01:15 PM JT-Shop: so I guess a tune up is in order for the Stihl
01:27 PM Loetmichel: .oO new clickspring video on youtube. $me is in awe and bowing down to the master. MAN that guy is GOOD!
01:29 PM drdoc: ooookay
01:30 PM drdoc: Dunno that it'll fix the jitter, but I think a copper heatsink will help this thing not lock up.
01:30 PM JT-Shop: damn the 021 runs better than new now
01:31 PM JT-Shop: only 998 projects left to finish now
01:31 PM SpeedEvil: And now they've started welding it
01:32 PM CaptHindsight: told you it would line up
01:33 PM CaptHindsight: why i have to turn the sound off if watching
01:35 PM gregcnc: playing card press? for playing card juice?
01:37 PM drdoc: hrrmmm
01:37 PM drdoc: I wonder if this PCI modem is a problem
01:37 PM drdoc: :-)
01:56 PM miss0r: !seen pink_vampire
01:56 PM miss0r: seen pink_vampire
02:02 PM rmu: new clickspring video
02:02 PM miss0r: watching it at the moment :)
02:02 PM rmu: https://www.youtube.com/watch?v=3PwAQZNLy0I
02:03 PM miss0r: I wish I had his patience
02:06 PM miss0r: he is just a damn magician!
02:09 PM miss0r: the thing is; most of what he is doing could be acomplished with a 5-axis cnc... but "everyone" can do that
02:12 PM rmu: most of what he is doing can be accomplished even without a CNC :p
02:13 PM miss0r: rephrase: can be done faster & easier
02:13 PM miss0r: But he realy has my respect
02:15 PM Tom_L: aww hell, any rookie can do that :) just ask em
02:15 PM miss0r: yeah hehe
02:15 PM miss0r: Tom_L: I added some more photos from todays progress of my project, if you want to see?
02:16 PM Tom_L: saw some already i think
02:16 PM miss0r: as in; 20 minuts ago? :D
02:16 PM Tom_L: milling the side of the block
02:16 PM miss0r: https://imgur.com/a/dYKc3V4
02:16 PM miss0r: yeah - also added a test fitup
02:17 PM Tom_L: sry the just don't look as good as Ramsay's
02:17 PM miss0r: Can someone tell me what the purpose of a card press is? :D
02:17 PM Tom_L: :)
02:17 PM miss0r: no - it does not :D
02:18 PM CaptHindsight: miss0r: ever try to play poker with crumpled cards?
02:18 PM Tom_L: dunno, maybe to keep them flat or to keep humidity out
02:19 PM CaptHindsight: why I'm a fan of metal or plastic cards
02:19 PM miss0r: CaptHindsight: I've come to the conclusion that I loose either way - crumbled or not
02:20 PM CaptHindsight: could have more uses....
02:20 PM CaptHindsight: pasta press
02:20 PM CaptHindsight: cash press
02:20 PM CaptHindsight: salami press etc
02:21 PM Tom_L: for bent cards
02:21 PM miss0r: Tom_L: Next time I'll build the gearbox from polished brass to get your approval ;D
02:21 PM Tom_L: mkay
02:21 PM Tom_L: but it better shine!
02:22 PM CaptHindsight: https://www.theory11.com/forums/threads/card-press.47086/
02:22 PM miss0r: meh... I'm probably better off making stuff from cast iron. That way I can always blame shitty surface finish on the quality of the cast :D
02:22 PM Loetmichel: miss0r: you think a bad quality cast will stop clickspring?
02:22 PM Loetmichel: i doubt it ;)
02:23 PM miss0r: not clickspring, no. He will just spend three days filing it untill it looks like solid gold. I'm talking about me, a mere mortal
02:23 PM CaptHindsight: playing card arbor press!
02:23 PM gregcnc: playing card extrusion press
02:24 PM Loetmichel: miss0r: indeed ,)
02:26 PM Loetmichel: miss0r: i sat on my old 1961 truck with a rotating flapper disk in one hand and the MIG welder in the other and repaired the holes in the body... so i know a bit like he feels when he is done... but i must say that i would run out of patience fast with that engraving there in the vid
02:26 PM gregcnc: https://youtu.be/RhdFg6vSLWA
02:28 PM miss0r: Loetmichel: Yeah. I build a 1972 land rover chassis from scratch. Started as a flat sheet I cut with a jigsaw & welded into shape. I know the feeling :) I'm just not up for that stuff anymore
02:28 PM Loetmichel: same
02:29 PM miss0r: I think I spend over a year worth of weekends doing that thing
02:29 PM CaptHindsight: https://youtu.be/xpJ8EoGmLuE?t=156
02:29 PM miss0r: the car sits in my driveway now - I still love it :D
02:30 PM miss0r: and even with the quite rising pricetag on the old lady, I would never sell it. And if I did I would come out having worked for 12cent/hour
02:30 PM Loetmichel: yeah
02:31 PM Loetmichel: the satisfaction to have an old car repaired and painted without the need of a single ounce of putty though...
02:31 PM Tom_L: i bet he made coins for the US mint at one time
02:31 PM Loetmichel: all welded and ground back into form ;)
02:31 PM Loetmichel: Tom_L: probably ;)
02:33 PM miss0r: I think he works part time hand engraving silver dollars
02:38 PM CaptHindsight: people never value the time spent restoring a car
02:39 PM Tom_L: some do
02:39 PM CaptHindsight: the person that did the restoration
02:40 PM CaptHindsight: was watching a recent classic car auction, i was shocked by how low they were going for
02:43 PM t4nk-freenode: 'the person Who', not the person that.
02:46 PM gregcnc: discribe' please?
02:46 PM jthornton: classssss
02:47 PM CaptHindsight: grammar police have arrived
02:47 PM CaptHindsight: what grade school did you teach?
02:49 PM t4nk-freenode: you never answered me when I asked about your experience with encoder output, CaptHindsight, perhaps it will ring a (school) bell
02:49 PM CaptHindsight: you never paid for support
02:49 PM t4nk-freenode: I never asked for it from you
02:50 PM CaptHindsight: plus it would take to long to get any useful info from you to provide an answer
02:50 PM t4nk-freenode: 'too', not to
02:50 PM CaptHindsight: see
02:51 PM miss0r: o_0
02:51 PM miss0r: on the support subject: What oil would you guys recommend I use to rust protect the cast iron slab here?
02:52 PM CaptHindsight: something that sticks vs runs off
02:52 PM miss0r: sure - but I wouldn't want to end up with a sticky surface
02:52 PM Tom_L: i put vactra 2 on my vise
02:53 PM CaptHindsight: non sticky oil?
02:53 PM miss0r: Normally I use some rocol ultraglide X5 (the same stuff I use for my linear ways ect.) then wipe most of it off again
02:53 PM CaptHindsight: machined surface?
02:53 PM miss0r: But I seem to recall seeing some sort of protective oil at some point to seep into pores ect
02:53 PM miss0r: yeah
02:53 PM miss0r: CaptHindsight: ^
02:54 PM CaptHindsight: anything is better than nothing
02:55 PM miss0r: true.
02:55 PM CaptHindsight: will it be getting wet?
02:55 PM CaptHindsight: besides humidity
02:56 PM miss0r: hmm... perhaps the occational flood coolant splash
02:56 PM miss0r: but not realy wet per say
02:59 PM CaptHindsight: if you are not going to paint it
02:59 PM miss0r: I wasn't planning on it, no
03:00 PM miss0r: https://imgur.com/gallery/xhcr9
03:00 PM miss0r: I feel the same way for paint :P
03:00 PM gregcnc: I like the waxy types for long term. boeshield t9, LPS -3 must be somethign similar over there
03:00 PM miss0r: yeah. I have a bucket of waxoil
03:00 PM miss0r: I was hoping for something that would sorta seep in :)
03:01 PM miss0r: Firing up the mill to make the second slot in the side. be back later
03:01 PM CaptHindsight: heat it
03:01 PM CaptHindsight: it should be barrier for oxygen
03:02 PM gregcnc: check out this drilling op https://www.instagram.com/p/B27T9bQJohS/
03:02 PM gregcnc: volume down
03:03 PM CaptHindsight: the lower the viscosity the quicker it will run down the vertical surfaces, leaving a thinner barrier
03:03 PM CaptHindsight: so like gregcnc said, wax vs oil
03:03 PM CaptHindsight: higher viscosity vs lower, but anything is better than nothing
03:05 PM miss0r: I guess its a tradeoff of not being too dirty when touching it vs having it rust
03:05 PM miss0r: (I keep my machinery clean)
03:05 PM miss0r: as in: you don't get dirty hands operating it... UNLESS I AM WORKING ON CAST IRON! THEN ALL IS DIRTY NOTHING IS CLEAN !
03:06 PM CaptHindsight: I picked up a lathe a few years ago that was stored for 20+ years
03:06 PM CaptHindsight: it was coated in wax before they stored it
03:07 PM CaptHindsight: no visible rust
03:07 PM miss0r: alot of cleaning to get it in shop worthy condition?
03:08 PM CaptHindsight: no just a wipe down with solvent
03:09 PM gregcnc: solvent and non abrasive scotchbrite pad is awesome
03:11 PM CaptHindsight: https://i.imgur.com/OVgL40b.jpg the chuck was not coated
03:15 PM CaptHindsight: the motor burned out but the hydraulic speed adjustment just needed bleeding
03:44 PM drdoc: I have a relative who made a cash press
03:45 PM drdoc: the Treasury was Not Amused
03:45 PM drdoc: OK, realtime setup and latency questions:
03:46 PM drdoc: is it normal to get a big spike, like 40uSec, in the base thread when you start the latency test?
03:46 PM CaptHindsight: yes
03:46 PM Elmo40: sure
03:47 PM CaptHindsight: restart and abuse it
03:47 PM Elmo40: just dont get any more spikes...
03:47 PM CaptHindsight: run FF and a youtube
03:48 PM Elmo40: and play Super Tux Kart ;-)
03:48 PM CaptHindsight: it's just coincidence but we noticed that the latency is worst the first time it is run, even after reboots, the very first run is usually the worst
03:49 PM CaptHindsight: other spikes have been a few uS every day or so
03:49 PM Elmo40: might be writing to a new file in the beginning? hdd write/read speeds might distort the outcome
03:49 PM CaptHindsight: so 24hrs of testing ~15uS, after 7 days ~30uS
03:49 PM drdoc: I do get a big spike, from 8-9 uSec to 35 or so, about every 6-8 minutes
03:50 PM CaptHindsight: all power management killed in BIOS?
03:50 PM drdoc: IHNI what that is. Single-core proc, no HT, all the PM I *can* kill is kilt
03:50 PM CaptHindsight: ah single core
03:50 PM drdoc: plus the plethora of Ubuntu PM daemons are disabled
03:51 PM drdoc: the 2 last possible gremlins are the ATI X300 card and the onboard Broadcom NIC
03:52 PM CaptHindsight: well BIOSes are generally broken
03:52 PM drdoc: the only other video cards I have are either NVidia or <32MB
03:52 PM CaptHindsight: but you only have one core for RT and userland
03:52 PM drdoc: have the rtai_smi module loading, which helped a ton, as did setting cstate and polling in GRUB
03:52 PM drdoc: yeah
03:52 PM CaptHindsight: we didn't do much work on single core processors and RTAI
03:53 PM drdoc: there's an E8500 on the way for the other machine
03:53 PM drdoc: that one, Optiplex 320, happened to be one of Tormach's recommended systems, so I'm hopeful
03:54 PM Elmo40: drdoc, you didnt use the iso image? you installed the RT kernel and linuxCNC onto *buntu?
03:54 PM drdoc: I installed from the livecd
03:54 PM CaptHindsight: try idle=poll
03:54 PM drdoc: I did
03:54 PM CaptHindsight: see if it's gets better or worse
03:55 PM Elmo40: single core??? why mess with that?
03:55 PM Elmo40: how much RAM?
03:56 PM drdoc: Elmo40: mostly to figure out how the RT hal works
03:56 PM drdoc: 4GB
03:56 PM CaptHindsight: drdoc: the old Wheezy ISO or the Stretch?
03:57 PM drdoc: ummm, 10.04
03:57 PM drdoc: which was the next question
03:57 PM Elmo40: i was just reading on the website that 2.8 supports gantry dual motor homing. doesnt current stable support that?
03:58 PM drdoc: once I turned off all the excess crap, that P4 is running 10.04 pretty briskly
03:58 PM drdoc: would the Wheezy build be better?
03:58 PM CaptHindsight: try the Stretch ISO, different kernel and different RTAI branch
03:58 PM drdoc: that's the userland realtime?
03:59 PM CaptHindsight: sorry i forget
04:00 PM ve7it: I still run my lathe/mill on 10.04... its on an old 800Mhz PIII, works just great... it was running Ubuntu 8 before the upgrade to 10 and the latency graphs were even better.
04:00 PM CaptHindsight: we develop RTAI here and I forget what the LCNC devs use
04:00 PM drdoc: heh
04:00 PM drdoc: the download page sez yes
04:00 PM CaptHindsight: I have RTAI on wheezy, Stretch and Sid
04:00 PM drdoc: Stretch is uspace
04:01 PM drdoc: ok, one last question, that I'm embarassed to even ask
04:01 PM drdoc: are those $8 chinese breakout boards any good?
04:01 PM CaptHindsight: yes and no
04:01 PM drdoc: it's probably already obvious I'm doing this on the cheap
04:01 PM CaptHindsight: some use really slow optos
04:02 PM drdoc: the 817?
04:02 PM CaptHindsight: i have several
04:02 PM CaptHindsight: some chinese clone opto
04:02 PM drdoc: ah
04:02 PM CaptHindsight: so some had limited step rates
04:02 PM drdoc: I use the Vishay 817 variant for power supply switching
04:03 PM drdoc: they aren't as fast as the 6n series, but they do ok
04:03 PM CaptHindsight: http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Building_RTAI_5.2_Packages
04:03 PM drdoc: is 5 optocouplers enough?
04:04 PM drdoc: that's what most look to have
04:05 PM drdoc: ooooh, dev builds
04:05 PM CaptHindsight: drdoc: I have a dual core celeron board that is faster on preempt_rt than with RTAI
04:05 PM drdoc: that's nice to know
04:05 PM CaptHindsight: so your older hardware might be similar
04:06 PM CaptHindsight: the latest RTAI is faster on Intel than AMD
04:06 PM drdoc: I have a supermicro D510 mini-ITX board that's giving *really* disappointing numbers with Wheezy
04:07 PM drdoc: it doesn't have slots for discrete video and a parallel card, so it's academic
04:07 PM CaptHindsight: it also varies from kernel to kernel
04:07 PM drdoc: anyway, the breakout boards
04:08 PM drdoc: are there things to look for/avoid?
04:09 PM drdoc: a couple hundred bucks for interface gear isn't going to happen for a while
04:12 PM drdoc: ve7it: I actually have a PIII 800, but it's pre-DDR DIMMs and I could buy a whole C2D mb set for the price of RAM
04:12 PM sync: or just get something current
04:12 PM drdoc: sync: all this is existing hardware
04:13 PM drdoc: so far total layout has been $5 for a processor
04:13 PM drdoc: but yes, I'd like to run something that doesn't heat the house
04:15 PM sync: get something with dual ethernet
04:15 PM drdoc: oh?
04:15 PM drdoc: oh, for a breakout?
04:15 PM Deejay: gn8
04:16 PM drdoc: are there schematics for the various breakout boards?
04:21 PM drdoc: I found Probotix' docs, and a dozen "I haven't actually built this but here's a better parallel breakout design" projects
04:26 PM sync: they are all the same more or less for LPT
04:34 PM miss0r: finally - other side of block done
04:35 PM miss0r: Now I just need to drill in an oil nipple & ream two holes.
04:43 PM sync: andypugh: I was really suprised with the condition of my engine
04:44 PM sync: after 320Mm
04:44 PM sync: very clean and you can't see the typical wear marks on the cam where maximum pressure happens
04:44 PM sync: or on the end of the pistons stroke
04:44 PM sync: and the cams are hollow :D
05:02 PM SpeedEvil: sync: Oil is awesome
05:03 PM SpeedEvil: (and proper bearing design)
05:03 PM sync: yes, but that just means that I'm not making enough Nm/cyl
05:05 PM sync: I guess I'll have to knock the DPF out to relieve some temperature
05:05 PM sync: although I'm also really suprised how well it still looks
05:06 PM Wolf__: thats something I need to do to my vw
05:07 PM miss0r: gah. Finally finished with the first major component of this build.
05:08 PM miss0r: also: What is wrong with me for getting a hand reamer!
05:08 PM miss0r: it is impossible to get a tolerance to fit inside a narrow blind hole with that thing :D
05:09 PM sync: oh wow, VW is making below 100Nm/cyl on their 2.0TDIs
05:09 PM sync: no wonder their air pumps are slow on the bahn
05:14 PM Wolf__: @ crank output?
05:14 PM Wolf__: I just looked up, stock is 305Nm =/
05:16 PM andypugh: I am astonished how difficult it seems to be to find somewhere that is open on a saturday round gere that can sell me some Petrobond casting sand!
05:16 PM Wolf__: looks like with a stage 2 tune/delete my 2.0L CR would be putting out 439-451Nm
05:16 PM andypugh: Please don’t
05:17 PM andypugh: Just get something that makes more power _and_ meets the emissions regs.
05:20 PM Wolf__: total cost of the tune +dsg tune + delete kit isnt really worth it to
05:20 PM Wolf__: me to do
05:22 PM sync: andypugh: the problem is that the stock tune on those air pumps just doesn't do it
05:25 PM Wolf__: oh, that I didnt know, malone stage 2 tune will work with emissions intact
05:26 PM sync: well, you will not hit the NOx target
05:26 PM sync: it just won't haze visibly
05:28 PM Wolf__: so, like it did before the recall ecu flash? lol
05:29 PM sync: it did hit the NOx target in the testcycle
05:30 PM sync: https://pbs.twimg.com/media/DpVX97iWkAI10Oa?format=jpg&name=900x900
05:30 PM sync: that's the one you need
05:30 PM Wolf__: lol
05:31 PM sync: that turns all the DPF functionality off in an EDC17
05:33 PM sync: turning off EGR has a _significant_ effect on NOx output
05:33 PM Wolf__: mine is a 2015 MK7 sportwagen, I dont know the ECU stuff that much
05:33 PM sync: the difference between rene_devs tune and mine is quite big
05:35 PM Wolf__: lifetime average for my car is 37mpg-7.6L/100k with 107 fill ups lol
05:36 PM sync: oh, that is quite bad
05:37 PM Wolf__: I’ve seen 42.6mpg/6.63L/100k but that was pure highway road trip driving
05:37 PM sync: I'm running ~8.1l/100km with 98.4kmh avg
05:39 PM sync: oh of course you get the USDM engine...
05:40 PM Wolf__: yep
05:41 PM Wolf__: could be worse, my truck gets like 21.7L/100K lol
05:41 PM Wolf__: er 100km
05:42 PM sync: well, then you have even smaller injectors
05:42 PM sync: the 2.0tdi is running quite close to what the nozzles can flow
05:42 PM jthornton: my truck gets 16 MPG downhill...
05:46 PM XXCoder: lol my bro truck gets 16 mpg if we turn engine off and push it ;)
05:46 PM XXCoder: normally like 8 mpg?
05:47 PM jthornton: geez what kind of truck is that?
05:47 PM jthornton: mine is a 02 chevy z71 4 wheel drive 5.3l IIRC
05:48 PM XXCoder: forgot its late 1940s? ford truck
05:48 PM Wolf__: thats kinda bad, my dad’s ’12 F350 6.7 was getting 18mpg+ when I was driving it
05:50 PM jthornton: yea mileage on trucks has been getting better since I got mine in 01
05:50 PM XXCoder: i dont plan to own a truck
05:50 PM jthornton: got a random miss now to try and find in the truck
05:51 PM Wolf__: on the other hand, I used my mom’s prius and it was getting 30mpg w/ me driving it lol
05:51 PM jthornton: if you don't need one...
05:51 PM jthornton: I thought a prius got better mileage than that
05:52 PM Wolf__: not at 80mph all highway driving
05:52 PM XXCoder: 30 mph here, but will improve now that its been fixed on recalls
05:52 PM XXCoder: ford focus 2012
05:52 PM XXCoder: morons in disel trucks dont know cars, few of em coal rolled me lol
05:53 PM XXCoder: very rare here but it happens
05:53 PM jthornton: coal rolled?
05:54 PM XXCoder: yeah some diesel truck owners modify their truck to burn badly at command to smoke out prius owners (note my car is not prius!)
05:54 PM Wolf__: blowing black clouds of unburnt fuel cause f’kn idiots
05:55 PM _abc_: Hi. Silly question: is it reasonable to polish/reduce the shaft diameter of 2.5mm metric drills/axles to "Dremel" 2.35mm? Using abrasive paper, perhaps in a lathe?
05:55 PM _abc_: 0.15 mm down is not going to take too long, I think?
05:56 PM _abc_: I would like to use a 2.5mm shafted tool (engraver) I shaped in a Dremel like collet which does not accept 2.5, too big
05:56 PM Wolf__: eh, 2.35mm dremel?
05:56 PM _abc_: The shafts are 2.33-2.36 for after market Dremel bits.
05:57 PM _abc_: Measured a dozen or so.
05:58 PM _abc_: I think 2.34 is the exact dimension of the perversion. Would not be surprized it it is trademarked/patented even. Right up there with certain radius round corners and yellow and black DVM cases.
05:59 PM sync: you can just get a 2.5mm collet
06:00 PM _abc_: No I can't, this thing I am trying to use is a Chiense battery operated thing with a plastic collet which does not take 2.5, only 2.34
06:00 PM sync: Wolf__: to some degree you can't avoid soot in a purely torque driven diesel application
06:01 PM Wolf__: sync: yeah I understand that, get some over-fuel at spool up
06:01 PM _abc_: Actually afaik soot can be avoided using Methane in a Diesel engine...
06:02 PM _abc_: Also NOx can be avoided by running it on O2 ... Sumbmarines did that at one time (Walther)
06:02 PM _abc_: The O2 running Diesel.
06:03 PM sync: no, not really Wolf__
06:03 PM sync: if you want maximum torque you will get some soot
06:03 PM _abc_: So, anyone, is abrasive only "turning down" the shaft 0.07mm feasible?
06:03 PM sync: try it
06:04 PM _abc_: sync: are you in Europe? Apparenlty not. Around here the soot thing is a nono, so they did get the Diesels to not belch any.
06:04 PM _abc_: Takes special instruments to see the soot output in an Euro 4+ vehicle's exhaust.
06:05 PM jthornton: XXCoder, that's just dumb
06:05 PM XXCoder: exactly
06:06 PM XXCoder: its also illegal, so if police see they will arrest
06:06 PM XXCoder: i wonder if theres police driving in prius see if they get coal rolled
06:06 PM sync: well, an opacimeter is not really specialized
06:07 PM _abc_: Hm, unrelated, but interesting https://www.sciencedirect.com/science/article/pii/S000785060900095X
06:07 PM _abc_: sync: opacimeter is not going to see that here. There's 2 catalyzers in between and the blue tec urea injector.
06:08 PM _abc_: sync: we're talking nanometer particles
06:09 PM _abc_: What is needed to abrade HSS? SiC will not work properly? Only diamond?
06:10 PM _abc_: CBN is Boron Nitride right? https://www.superabrasivetools.com/cbn-abrasive-belt/
06:51 PM _unreal_: If I'm not mistaken the UK banned TEFgel claiming its cancerous. When every review says its non toxic non this non that... LOL
06:52 PM XXCoder: review? not research?
07:25 PM elmo40: for building a new rig, AMD or Intel for the CPU?
07:31 PM CaptHindsight: been using mostly AMD for the past 20 years
07:31 PM elmo40: CaptHindsight, about the convo you were having with drdoc; for a late model computer&hardware (with no par port), which linuxCNC should i be downloading? you mentioned trying the Stretch image but it has an older version of linuxcnc than the wheezy image. and it says a 4.x kernel is made in the wheezy image... i guess i can try each one and see which one gives me best latency numbers?
07:32 PM CaptHindsight: the Stretch image lets you choose the LCNC version
07:32 PM elmo40: ok
07:32 PM CaptHindsight: I installed 2.8 and master a couple months ago
07:33 PM CaptHindsight: building a preempt_rt patch is not much work
07:33 PM CaptHindsight: anything better than 200K is fine for me since I use Mesa FPGA's
07:34 PM CaptHindsight: but we did use some celeron dual cores this summer and preempt_rt and they ran ~28uS
07:35 PM CaptHindsight: doesn't JT have a bunch of howtos for building preempt_rt patches and LCNC for lots of distros?
07:36 PM CaptHindsight: https://gnipsel.com/linuxcnc/uspace/index.html
07:36 PM CaptHindsight: elmo40: ^^
07:37 PM elmo40: not like you need the latest 16-core architecture, i get that. does it even matter if you use anything more than dual-core?
07:38 PM CaptHindsight: depends on what else you might be doing
07:38 PM elmo40: so many quad-core Intel i5 machines going for cheap
07:38 PM CaptHindsight: we use 2 and 4 core cpus
07:38 PM CaptHindsight: thats what is available for low cost and works
07:38 PM elmo40: true
07:39 PM andypugh: The trucks I drive for work can do 47mpg on a run at 75mph on the cruise control. (That’s the 2.0 litre Ranger)
07:39 PM elmo40: these are 32 or 64-bit? i have my eye on a machine with 8GB of DDR3 RAM (board can handle 32, though)
07:39 PM elmo40: andypugh, diesel?
07:40 PM elmo40: if it doesn't have built-in parallel port, do i need to get a pci-par port card?
07:40 PM CaptHindsight: elmo40: 64b Ryzen's
07:41 PM CaptHindsight: usually 8GB DDR4, never run out of space
07:41 PM CaptHindsight: elmo40: we use PCIe --LPT cards that are ~$10 delivered
