12:23 AM evilroot: Starrett . . .
12:26 AM evilroot: That name has rather plauged me
12:26 AM evilroot: I have a complete Starrett Rapid Check II CMM
12:26 AM evilroot: X.X
12:26 AM evilroot: And no idea what to do with it
12:32 AM skullworks: How big is it?
12:37 AM skullworks: I used to run a very Nice Mititoyo - but the PC interface PCB required W98 and the software was a ROID to set up. But once you got it set, Zoom. It was off and running with auto prob changing and it would print out reports with thousands of data points.
12:39 AM skullworks: So with a color printer - just look for any numbers in RED - if all 14-17 pages were black and green you were in the Golden zone.
01:25 AM IchGucksLive: Good morniung from Germany
01:36 AM gloops: hi Ichs
01:36 AM gloops: building anything new atm?
01:42 AM IchGucksLive: today the schools got a "walkingDay" so no action
01:45 AM gloops: well, have been too busy with work to do anything with mine, but will be sorting a few mechanical issues out over the weekend, then good to go
01:45 AM gloops: oh, need to get vfd wired up to computer
01:47 AM gloops: developed a noticeable backlash issue last few cuts, lot of stressing checking this and that - slipping coupling
01:47 AM IchGucksLive: VFD is wirerd to BOB
01:47 AM IchGucksLive: on pc/LCNC its a spindle
01:48 AM IchGucksLive: http://linuxcnc.org/docs/html/examples/spindle.html
01:49 AM gloops: yes will be studying that thanks, for once i did get some instructions with the chinese kit but it doesnt make much sense haha
01:50 AM gloops: it is running simple on off on the panel, but only at 24000
01:53 AM gloops: this is going to be a challenge, im not a coder
01:53 AM IchGucksLive: if you got a standard BOB you might got PWM-Y analog
01:53 AM IchGucksLive: as the VFD takes this
01:54 AM IchGucksLive: so you need 3 or 4 wirer
01:55 AM IchGucksLive: 0-10V GND and FWD mabe VFD is a Positiv so you need to the BOB relai FWD/ VFD+
01:55 AM IchGucksLive: if you tell us here what BOB and what VFD you are up
01:56 AM gloops: will get the info and ask when im starting to do it, not much clue about these details atm
01:57 AM gloops: the bob is just standard db25 chinese
01:57 AM gloops: the vfd readout is in khz i think goes up to 400
01:58 AM IchGucksLive: if it is this one https://www.youtube.com/watch?v=I00ArvYvZgI
01:58 AM IchGucksLive: hen yiou are up at a glimp
01:58 AM MrSunshine_: hmm an inductive sensor, is a slideby better than when the material comes up to it linearly ?
01:58 AM gloops: similar to that
01:58 AM IchGucksLive: inductiv are best to go headon
01:59 AM IchGucksLive: gloops: does it have the pwm
01:59 AM IchGucksLive: gloops: and the relai
01:59 AM MrSunshine_: so (sensor) --- | plate .. linear move towards the sensor ?
01:59 AM IchGucksLive: yes then they are perfect within 0,05mm
01:59 AM MrSunshine_: aight =)
02:00 AM IchGucksLive: sideways it depends on humanity
02:00 AM IchGucksLive: and offen a failue kills the sensor
02:00 AM MrSunshine_: was far easier to mount them for headon move also .. on this axis
02:00 AM MrSunshine_: on the other axis it will be a pita
02:00 AM IchGucksLive: sideways you may need a angel Plate
02:01 AM MrSunshine_: hmm, dont know if were talking the same language here ...
02:01 AM IchGucksLive: i use them sideways on Rotary
02:01 AM MrSunshine_: ive got the sensor in line with the axis, with the readhead int he travel direction of the axis
02:01 AM IchGucksLive: with a non touching plate angle
02:02 AM gloops: not here with me, hmm i do seem to remember pwn label somewhere
02:02 AM IchGucksLive: |
02:02 AM IchGucksLive: /
02:02 AM IchGucksLive: _|
02:02 AM gloops: i will check later, not much point asking if i havent got the info
02:03 AM IchGucksLive: gloops: this BOB is at 5USD and it is worth any cent
02:03 AM IchGucksLive: you also can go ethernet and 8Axis on that with a 7i92
02:04 AM gloops: yeah, had to think hard about sending $5 haha
02:04 AM IchGucksLive: gloops: all infos are here in the channel
02:04 AM IchGucksLive: gloops: where in the word are you
02:04 AM gloops: yeah i mean the info about the hardware, its in the garage ill look later
02:05 AM gloops: im in the UK - it was £5
02:05 AM IchGucksLive: im in germany
02:06 AM IchGucksLive: gloops: https://www.ebay.co.uk/sch/i.html?_from=R40&_sacat=0&_nkw=mach3+interface+board&_sop=2 3Pound
02:07 AM IchGucksLive: 13pounds in glasgow http://www.ebay.co.uk/itm/5-Axis-MACH3-Interface-Board-CNC-With-Optocoupler-Adapter-Stepper-Motor-Driver-/281531923534
02:08 AM IchGucksLive: i have always 10 here
02:08 AM gloops: https://www.youtube.com/watch?v=bWVKJUnSLUc
02:08 AM gloops: mine is exactly that, board and drivers
02:08 AM gloops: standard kit from longs
02:08 AM gloops: db25-1205
02:09 AM IchGucksLive: there is no PWM-analog and no relay for the VFD so all extra cost
02:09 AM IchGucksLive: gloops: and the costs are more then double then the BOB i posted
02:10 AM gloops: http://i.ytimg.com/vi/7Y1-sEO2KCY/mqdefault.jpg
02:10 AM gloops: 0-10v pwn output there - there are 5 output pins i think
02:11 AM gloops: bigger photo would help
02:12 AM IchGucksLive: yes this has all lthe stuff you need
02:12 AM IchGucksLive: right on it just connect
02:12 AM IchGucksLive: no extra needed
02:13 AM gloops: https://wiki.hive13.org/images/e/e0/New_5axis_breakout_board_interfaces.fw_r2_c1.png
02:13 AM gloops: this is so common a board, yet so little info online
02:13 AM IchGucksLive: yes also the same
02:13 AM IchGucksLive: the with connectors are JST-XH-3S
02:13 AM IchGucksLive: so you need less wirer and can unplug easy
02:14 AM IchGucksLive: whithe
02:14 AM IchGucksLive: white
02:15 AM gloops: i really need to have the hardwre in front of me and a diagram to get my head round it lol, just the way my brain works
02:17 AM Deejay: moin
02:18 AM IchGucksLive: gloops: http://heimwerkermarkt-tretter.de/hf_e.pdf
02:18 AM IchGucksLive: gloops: this skoudt get you a idee
02:19 AM IchGucksLive: gloops: here is the coresponding cabinet http://heimwerkermarkt-tretter.de/5achs_elek
02:19 AM IchGucksLive: Deejay: Blauer himmel !?
02:23 AM IchGucksLive: im off later Bye
02:28 AM gloops: well i want this thing fully operational next week, i have a product that i can make right away, im losing cash here
02:36 AM archivist: I did production long before I bothered with vfd speed control
02:38 AM gloops: yes that is true enough, my set up was working fine with a router, just thought id get the machine finished before i started anything
02:39 AM archivist: I even still had manual on some axes as well
02:40 AM archivist: rotary and X for the first gear
02:41 AM archivist: then rotary and XY for a while
02:41 AM archivist: eventually added a motor to Z
02:41 AM gloops: i only need basic surfacing operation and profiling, may as well get it right and reliable first though
02:42 AM archivist: doing actual production showed me some of my mistooks
02:43 AM archivist: development/modification continued for some years
02:44 AM gloops: yes theory is only good to an extent, the real world tells the true story
02:44 AM * evilren waiting for related neato archivist pics
02:45 AM evilren: real world should confirm theories, else the theories suck
02:45 AM evilren: ive never had anything irl not obey ohms law
02:45 AM gloops: evilren yes, but no way of knowing the theory sucks before testing
02:46 AM jelly-home is now known as jelly
02:46 AM gloops: newton was wrong, einstein was wrong, hawking is wrong
02:46 AM archivist: evilren, er.... negative resistance :)
02:46 AM evilren: im pretty sure thats part of the process where theories happen
02:47 AM evilren: archivist: every voltage source?
02:47 AM archivist: memristor
02:47 AM evilren: i cant buy it at digikey so its not a thing
02:47 AM archivist: and other strangeness with some micrwave devices impatt diodes
02:48 AM archivist: parametric amplifiers
02:48 AM evilren: ohms law always applies, if not then you just havent sorted the parasitics
02:48 AM evilren: NO EXCEPTION!
02:49 AM gloops: you cant say that
02:49 AM archivist: dont see parametric amplifiers these days
02:49 AM gloops: as you cannot test the theory in all places and at all times
02:49 AM * evilren googles bc wtf is that
02:50 AM gloops: science doesnt prove anything
02:50 AM archivist: I have taken one apart
02:52 AM archivist: http://www.rfwireless-world.com/Terminology/Parametric-Amplifier-basics-advantages-disadvantages.html
02:52 AM archivist: about the best I can see on the web quickly
02:53 AM archivist: varacter and capacitance
02:56 AM archivist: evilren, what you were looking for :) http://www.collection.archivist.info/searchv13.php?searchstr=cnc+pd
02:57 AM archivist: it morphs as you scroll down
02:57 AM evilren: right so im pretty sure this all follows ohms law
02:57 AM archivist: ignoring other stuff that appears at the top etc
02:57 AM evilren: seems like charge pumping a parasitic cap or something
02:58 AM archivist: that and the directional couplers
02:58 AM archivist: varacter, not a parasitic cap
03:00 AM evilren: right but looks like varacter reverse biased looks like a series RC
03:01 AM evilren: capacitance change with frequency is normal stuff at high frequencies
03:01 AM archivist: a diode reverse biased and used as a variable capacitor
03:01 AM evilren: like, electrolytics not gonna work for ghz shit
03:01 AM evilren: right
03:02 AM evilren: but it looks like what varies the capacitance is an oscillator
03:02 AM archivist: pumped
03:03 AM archivist: some plumbing involved
03:08 AM evilren: http://www.collection.archivist.info/showresult.php?prog=1&srcprog=searchv13.php&srcdata=title&Type=PD&Accn_no=7830&subject=24617
03:08 AM evilren: neat
03:08 AM evilren: k nite
05:05 AM jthornton: morning
05:06 AM XXCoder: hey the jt
05:06 AM XXCoder: apparently they are also getting rid of machine I hate, okuma
05:06 AM XXCoder: yay!
05:06 AM jthornton: cool
05:06 AM XXCoder: machine that error out when tool change is to same tool as before, begone!
05:06 AM jthornton: are they getting new machines?
05:07 AM XXCoder: well remember when I said we got 11 machines from utah that went under?
05:07 AM XXCoder: 3 of larger ones will replace fadal and okuma
05:09 AM XXCoder: one of those 11 is this WEIRD haas cnc machine
05:09 AM XXCoder: its workspace is one foot Y, 5 feet X
05:09 AM XXCoder: roughly 2 feet Z workspace
05:09 AM XXCoder: great for long narrow parts I guess
05:10 AM jthornton: yea that is weird travels
05:11 AM XXCoder: it has TINY coolant tank lol
05:11 AM jthornton: temperature is going back up a bit
05:11 AM XXCoder: smaller than robodrill
05:17 AM jthornton: got the modifications to the automagic chicken door done last night so time to put it back in the coop
05:18 AM XXCoder: awesome :)
05:18 AM jthornton: yea, I put the door lock on it finally and did some sheet metal work on it
05:19 AM XXCoder: I'm impressed with robodrill to be honest
05:19 AM XXCoder: it keeps working forever
05:20 AM XXCoder: we have made over thousand parts on it so far, and its long grind part.
05:20 AM XXCoder: consider office mill keep breaking down
05:33 AM XXCoder: I see you uploded a video
05:33 AM jthornton: yea, showing the door lock I installed on the chicken door
05:34 AM XXCoder: https://www.youtube.com/watch?v=pzqJOcCXjrk lol
05:35 AM XXCoder: better video https://www.youtube.com/watch?v=X7wBFoMuqfs
05:35 AM jthornton: I saw a motorcycle with two of them
05:37 AM XXCoder: crazy
05:37 AM XXCoder: would be worse if it made minigun noise
05:37 AM XXCoder: or does it do that?
05:42 AM XXCoder: good. fuck that person. https://static.boredpanda.com/blog/wp-content/uploads/2017/05/revenge-stories-1-590c250f0ba96__605.jpg
05:46 AM jthornton: we have someone that throws their fast food trash out the window and if someone sees who is doing it we will pick it all up and dump it in their yard lol
05:46 AM XXCoder: geez. apparently owner kicked one of those dogshttps://static.boredpanda.com/blog/wp-content/uploads/2017/05/revenge-stories-17-590c7cc669e39__605.jpg
05:46 AM XXCoder: geez. apparently owner kicked one of those dogs https://static.boredpanda.com/blog/wp-content/uploads/2017/05/revenge-stories-17-590c7cc669e39__605.jpg
05:56 AM XXCoder: jthornton: I got remended of one time guy who parked at disabled spot. apparently people saw that so they used tons blue and white note-its
05:56 AM XXCoder: making car into disabled parking sign
05:57 AM XXCoder: he got angry, removed just some of it on front and side, tried to drive it, got arrested by cop on disabled parking and also driving under unsafe condition
06:11 AM XXCoder: JT-Shop: smart car. heh https://static.boredpanda.com/blog/wp-content/uploads/2017/05/590c375118bdc_2PpXvTAr__605.jpg
06:33 AM Tom_L: hey
06:34 AM XXCoder: hey
06:38 AM jthornton: morning
06:38 AM jthornton: can you add stuff like contacts to symbols?
06:39 AM Tom_L: descriptions?
06:40 AM jthornton: was wanting to put something like the relay in this photo https://i.stack.imgur.com/oLrBD.png
06:40 AM Tom_L: just add a pin to it if that's what you mean
06:41 AM Tom_L: then give the pin a name
06:41 AM Tom_L: i can't remember what layer you're supposed to do the symbol on though
06:42 AM Tom_L: it will determine where the mask shows up on the board though
06:42 AM Tom_L: 20 is the outline layer to define the board edge
06:47 AM jthornton: guess I better find a good tutorial for making a board with eagle lol
06:47 AM Tom_L: wow, it's been a long time since i did a lib part...
06:47 AM Tom_L: i'm gonna need to review a bit
06:48 AM Tom_L: you can mod just about anything in a lib part though
06:48 AM Tom_L: you first have to disconnect the pins if you make changes that affect the pins
06:49 AM Tom_L: you draw a symbol, you draw the outline and add pins to it then you connect them and save it as a part variant
06:49 AM Tom_L: i'm not exactly sure what you're asking
06:50 AM Tom_L: i would find a lib part that has a relay and mod it
06:50 AM Tom_L: that would be easier
06:50 AM Tom_L: then name it something else
06:50 AM Tom_L: create a new library. mine is called mylib :)
06:54 AM Tom_L: from the main pannel, file->new->library
06:54 AM Tom_L: then there you can create a symbol and a package
06:54 AM jthornton: yea mine is called JT
06:55 AM Tom_L: ok
06:55 AM Tom_L: you can also copy and paste those from other libs then mod them
06:55 AM Tom_L: depending what you mod, you may need to disconnect the pins first
06:55 AM Tom_L: all done in the library pannel
06:57 AM jthornton: yea, I've made a few parts so far so I kinda got the general idea of making them lol
06:57 AM Tom_L: i can help more later today
06:58 AM Tom_L: i need to review a bit myself. i used to have it all memorized :)
06:58 AM jthornton: https://intranet.ee.ic.ac.uk/t.clarke/EAGLE/The%20EAGLE%20Guide.pdf
06:58 AM jthornton: that looks like a good tutorial
06:58 AM Tom_L: sparkfun used to have one
07:03 AM Tom_itx: https://learn.sparkfun.com/tutorials/using-eagle-schematic
07:06 AM Tom_itx: https://learn.sparkfun.com/tutorials/making-custom-footprints-in-eagle
07:06 AM Tom_L: that's not the best but i think it explains it
07:06 AM Tom_L: ignore the bmp part
07:08 AM Tom_L: bbl
07:33 AM IchGucksLive: hi
07:34 AM IchGucksLive: Tom_l what part are you doing did you look in the 30000 libs already posted
08:14 AM Simonious: eagle eh? I thought KiCAD had won? *shrugs*
08:15 AM MrSunshine: ah homing works =) yeey .. now just to test this mofo =) need to lower the vacuum system by like 100mm but more than that im good to go! =)
08:49 AM JT-Shop: yea
09:11 AM Loetmichel2: *muhaha* Boss again. He ordered 20 Dell PCs for a customer. Delivery date monday... noticed a few hours ago that they have no 5.25" slot for the HDD cage... so the Michel has to make do... OSHA would have a party :-) -> https://youtu.be/KFBx4fIteIA
09:45 AM Tom_L: JT-Shop, figure it out?
10:51 AM JT-Shop: got more figured out
10:51 AM JT-Shop: ran into a snag with that tutorial
11:25 AM cradek: 1
11:26 AM cradek: oops
11:26 AM cradek: now I have to change my password to 2
11:26 AM jthornton: lol
11:28 AM Jymmm: cradek: Just make it NULL, nobody will ever guess that ;)
11:48 AM IchGucksLive: hi all ;-)
11:49 AM IchGucksLive: Loetmichel: i got 10 Tanks pc but they do not work for linux
11:50 AM IchGucksLive: hi gloo how is the bob doing :P
12:01 PM gloops: only just finished work Ich not looked yet
12:02 PM gloops: just inspecting a so called large area cutter from china that arrived lol
12:04 PM IchGucksLive: cool
12:08 PM Crom_: now to start sourcing material to make mounts to cnc the 44991 and start looking at ball screws
12:09 PM IchGucksLive: Crom there are nice cheep sets
12:09 PM IchGucksLive: but i gues you go for C5
12:10 PM gloops: some plans for that, dont know how much though http://www.stirlingsteele.com/mini-mill-cnc-conversion-plans.html
12:11 PM IchGucksLive: gloops: there are all different
12:15 PM gloops: well there are some cheap sets of ballscrews and bearing rails going - i was looking at some £150-200 for 3 axis, 2 1150mm ballscrews - not bad money
12:15 PM CaptHindsight: IchGucksLive: you posted a pic the other day of the insides of a control cabinet with 2-3 stepper drivers...
12:15 PM gloops: i guess you would want quality screws for a mill though
12:15 PM gloops: not so important for wood
12:15 PM CaptHindsight: there was a small fan in the lower right corner held by one fastener...
12:16 PM IchGucksLive: gloops: including square rails http://www.ebay.de/itm/EU-6Pcs-Square-Linear-Rail-Guide-L-400-700-1000mm-Ballscrew-1605-400-700-1000mm-/152680647211
12:16 PM CaptHindsight: do you use those to circulate air inside the enclosure?
12:16 PM IchGucksLive: this is the space for the 5th axis driver
12:17 PM gloops: good gear ichs
12:17 PM IchGucksLive: eatch driver got its own Fan
12:17 PM IchGucksLive: and 2 large 80mm for the cabinet
12:18 PM CaptHindsight: IchGucksLive: polymer enclosure?
12:18 PM IchGucksLive: CaptHindsight: you are refaring to this http://heimwerkermarkt-tretter.de/5achs_elek
12:18 PM IchGucksLive: yes
12:18 PM CaptHindsight: IchGucksLive: yes, that pic
12:19 PM IchGucksLive: i only build up to that stage the real mashine connections are doing others
12:21 PM IchGucksLive: let me find a running mashine view
12:22 PM gloops: this is cheap for 1350mm screws and bearings http://www.ebay.co.uk/itm/SBR16-300-1350-1350MM3-SETS-LINEAR-RAILS-3-SETS-BALL-SCREWS-BALLSCREW-RM1605-/311367687009?hash=item487ef5db61:g:DUsAAOSweW5VYtrM
12:22 PM CaptHindsight: gloops: beware of crunchy bearings
12:23 PM gloops: yeah probably better not to go too cheap
12:23 PM CaptHindsight: I'm not certain they understand what round or spherical really means
12:24 PM gloops: i made my own skate bearings for this build, pain in the ass though, they do work ok though
12:24 PM CaptHindsight: the mostI use Chinaco linear bearings for are drawer slide applications, never machine motion
12:24 PM IchGucksLive: gloops: this makes you a nice plasma or laser
12:26 PM gloops: well they are 16mm diameter, 1350 mm is a big ask though lol, maybe ok for a meter
12:26 PM IchGucksLive: CaptHindsight: there is a wire set cabinet http://heimwerkermarkt-tretter.de/4A_cab.jpg
12:26 PM Crom_: I have crunchy bearings on my 3040
12:26 PM IchGucksLive: with all the entries and Airstream outs
12:27 PM IchGucksLive: Crom_: thats why most build from near scratch
12:27 PM IchGucksLive: CaptHindsight: did you olso get the shematic
12:28 PM gloops: i used normal ball bearing races, mounted in slot so i could adjust them, i mean the carriages run fine and no play anywhere if you rock them about, i have not done any precision measurements as yet though
12:58 PM -!- #linuxcnc mode set to +v by ChanServ
01:05 PM markus_ is now known as mtt
01:05 PM IchGucksLive: hi mtt
01:06 PM mtt: Hi there...
01:06 PM IchGucksLive: ;-)
01:08 PM IchGucksLive: mtt bist du in deutschland
01:09 PM Deejay: hi
01:09 PM IchGucksLive: immer diese deutschne Deejay
01:10 PM IchGucksLive: heute hier schon alles weis
01:10 PM mtt: Moin ... jo aus dem Norden der Republik :-)
01:10 PM IchGucksLive: Berlin ?
01:10 PM IchGucksLive: ne hamburg
01:10 PM mtt: Lueneburg
01:10 PM IchGucksLive: ich sitze in Zweibrücken
01:11 PM mtt: Bin gerade durch Zufall auf deinen YouTube Kanal gekommen und mich dann mal gleich hier angemeldet.
01:12 PM mtt: Super Sache ! (y)
01:12 PM IchGucksLive: toll der hier https://www.youtube.com/channel/UCmwhCL92ZQRSVqFe3jGwJSQ/videos
01:12 PM mtt: Genau...
01:13 PM mtt: Meine Drehbank laeuft zwar schon zu 60% - natuerlich unter LinuxCNC aber ein paar Sachen fehlen noch zum Glueck.
01:14 PM IchGucksLive: mtt we shoudt go english as this is prfeut here
01:14 PM mtt: No problem...sounds good.
01:14 PM Deejay: prfeut?
01:14 PM IchGucksLive: Deejay: denglish
01:15 PM Deejay: nope, i think the word is br0ken
01:15 PM IchGucksLive: what ever you call it :O
01:16 PM CaptHindsight: IchGucksLive: schematics for the stepper drives and power supplies?
01:16 PM IchGucksLive: yes
01:16 PM IchGucksLive: the complete setup also the inductiv
01:17 PM CaptHindsight: too simple to require a schematic, i was just wondering about the lone fan
01:17 PM IchGucksLive: the cabinet is 5axis ready
01:17 PM IchGucksLive: as the sets come on 4axis
01:17 PM CaptHindsight: then you pointed out the other small fans on each stepper drive
01:18 PM IchGucksLive: yes

02:44 PM lenovo_: Moin, ich bin Marco Feinwerkmechaniker Meister...... spricht hier jemand Deutsch und kennt sich mit Heekscad aus? ich habe das Problem: wenn ich eine Kreistasche zeichne, und dann mit einen 3er Fräser 10mm tief mit 0,2mm Zustellung fräsen möchte dauert es ca. 5-8min bis die Bahnen errechnet sind.... der Prozessor Intel Core i5 ist dann voll ausgelastet... die gleiche Kreistasche in Megacad...
02:44 PM lenovo_: ...fräsen (Bahnen berechnen) dauert nur eine Sec. eventuell ist es eine Einstellung? ich weiß das wir hier bei Linuxcnc sind... aber eventuell kann mir hier jemand helfen. Das Wäre super!
02:58 PM cpresser: lenovo_: no clue. just use megacad
03:00 PM cpresser: or ask dan heeks :)

05:03 PM * sadisticroot yawns

06:05 PM sadisticroot: Holy crap, someone used LinuxCNC to run the same kind of SCARA robot I have!
06:06 PM SpeedEvil: :)
06:06 PM SpeedEvil: I think he's misleadingly outside the envelope fortunately
06:07 PM sadisticroot: Hmm?
06:19 PM cpresser: sadisticroot: is your scara running already?
06:20 PM * cpresser is working on a linuxcnc scara, but I am not happy with my config
06:20 PM SpeedEvil: sadisticroot: I mean that he is not in danger, though it looks like it can smash him on the head
06:21 PM cpresser: he might be just outside its radius
06:21 PM sadisticroot: Yeah mine runs, I just haven't converted it to modern control yet
06:21 PM sadisticroot: Just the teaching pendant
06:22 PM * cpresser needs to fix the servo amps next. closed-loop position control with linuxcnc does not work properly.. some tuning is needed
06:22 PM sadisticroot: I don't intend to keep it, just debating whether to sell it as is or do the full conversion first
06:23 PM sadisticroot: As cool as it would be to turn it into a crazy 3d printer or 5-axis mill or something haha
06:23 PM gloops: <Ben Stevic> strange problem to me. Linuxcnc BTW, If I say g54 g1 z-9.000 f40. It travels -9.0005 Perfect!!! But if I jog down using .001 incriments, after 4 clicks it actually travels .005 so if say jog .100 using .001 increments it will actually be off by a ton. What could cause this weirdness?
06:24 PM zeeshan: !seen andypugh
06:24 PM the_wench: last seen in 2017-09-13 07:36:44GMT 64:17:23 ago, saying Quit: andypugh
06:25 PM XXCoder: zeeshan: omg you are alive
06:25 PM zeeshan: yes
06:25 PM zeeshan: you are too :D
06:25 PM XXCoder: im not that certain
06:25 PM XXCoder: kidding heh
06:26 PM gloops: are the smaller jog increments accurate?
06:27 PM * zeeshan is sizing motors at work
06:27 PM zeeshan: its pretty crazy how accurate you can get from math
06:29 PM XXCoder: yeah?
06:36 PM sadisticroot: Sounds like a step resolution problem
06:37 PM XXCoder: zeeshan: hows ya
06:37 PM XXCoder: my work place is getting though interesting changes, they are getting rid of old fadal and okuma, and old cell
06:37 PM XXCoder: and more and more "infinity parts"
06:37 PM malcom2073: gloops: Have you stepped 0.001 a hundred times and measured? Or are you interpolating?
06:38 PM gloops: malcolm its just something someone asked me, hes not online atm
06:39 PM gloops: but could you explaina bit more?
06:40 PM malcom2073: gloops: If your dial indicator shows 0.005 when you moved 0.001, then either your machine is not precise enough, or your indicator is not. Either way, chances are, if you move 0.100 by doing 100 0.001 increments, you'll still be about a thou off, so 0.101 or 0.099
06:40 PM malcom2073: when you moved 4x0.001*
06:40 PM gloops: right im with you now
06:40 PM gloops: that does sound like his problem
06:41 PM gloops: <Ben Stevic> strange problem to me. Linuxcnc BTW, If I say g54 g1 z-9.000 f40. It travels -9.0005 Perfect!!! But if I jog down using .001 incriments, after 4 clicks it actually travels .005 so if say jog .100 using .001 increments it will actually be off by a ton. What could cause this weirdness?
06:41 PM gloops: ahh maybe not actually
06:41 PM malcom2073: he said "if say jog.....will actually be", meaning he didn't try it, it's just guessing
06:42 PM malcom2073: Anyway, have him come in here :)
06:42 PM gloops: i keep telling them to come here, they rarely do
06:42 PM malcom2073: You can lead a horse to water, can't make them drink
06:43 PM gloops: they ask on facebook, i think most people on there are using mach3
06:44 PM gloops: plus - kids on facebook have never heard of irc
06:44 PM malcom2073: Yeah I'm in a couple cnc router groups, lotta mach3, lotta people who really have no business running a machine tool, but have more money than sense :)
06:44 PM XXCoder: new leaning tower. https://interestingengineering.com/a-massive-multimillion-dollar-skyscraper-in-san-francisco-is-sinking-fast
06:46 PM roycroft: i thought they started trying to relevel that building several years ago
06:46 PM gloops: lol, you some bigshot yank 'hitting the trigger' on a 10k machine, then hes back asking if someone can draw him some text
06:46 PM gloops: you get some
06:46 PM roycroft: that article makes it out like they're just now starting to work on it
06:53 PM gloops: backlash compensation BACKLASH = this wont compensate on every move in the same direction will it?
06:54 PM gloops: surely only on a change of direction
07:04 PM XXCoder: "scissors" sure... https://interestingengineering.com/a-massive-multimillion-dollar-skyscraper-in-san-francisco-is-sinking-fast
07:04 PM XXCoder: er copy fail

08:21 PM Crom_: mount for the 65mm 1.5kw spindle showed up today
08:42 PM gloops: very good
08:43 PM gloops: i found some random kind of bracket in a box of junk that suits a spindle perfectly, stroke of luck actually, no idea what it came off
08:58 PM XXCoder: would be funny if it was spindle mount :P
09:01 PM gloops: haha
09:01 PM gloops: i doubt it somehow its pretty alloy
09:01 PM gloops: pretty old
11:21 PM * Skullworks will now preform his world famous Snoring in stereo!
11:48 PM * evilroot ponders on how to best clean linear rails
11:49 PM evilroot: There are a LOT of them so scotch brite pads and regular cleaners would be a bitch
11:49 PM XXCoder: clean no lint rag, then re-lube it
11:49 PM evilroot: Maybe kerosene?
11:49 PM XXCoder: honestly dunno but then as long as its nicely clean, and lubed so it dont rust it sjhould be fine
11:50 PM sadisticroot: o.O
11:50 PM sadisticroot: WTF?
11:51 PM sadisticroot is now known as evilroot
11:51 PM evilroot: That was odd
11:52 PM evilroot: But yeah, old caked on nasty grease
11:52 PM evilroot: And some minor corrosion (Luckily not on the actual bearing paths)
11:52 PM evilroot: The rails themselves are tool steel
11:53 PM diginet_ is now known as diginet
11:59 PM MarcelineVQ: evilroot: incentive to build an ultrasonic cleaning tub?
