12:21 AM XXCoder: Tom_L: jthornton https://youtu.be/jTdDBzkMwVQ
02:20 AM Deejay: moin
02:21 AM XXCoder: hey Deejay
02:21 AM XXCoder: check this out https://youtu.be/jTdDBzkMwVQ
02:21 AM Deejay: frosty outside. -3,5°C minimum
02:21 AM Deejay: hey XXCoder
02:22 AM XXCoder: looks like 40s F here, lowest is 38f. definitely warmer lol
02:23 AM Deejay: heh cool
02:23 AM Deejay: virtual cnc :D
02:23 AM XXCoder: vismach yeah
02:24 AM XXCoder: took me pretty long while to get to work'
02:33 AM Deejay: but what is it good for? ;)
02:37 AM XXCoder: sim machine
02:37 AM XXCoder: see if gcode is good
02:37 AM XXCoder: its also to figure vismach which is kinda on way to being lost art
03:10 AM XXCoder: this is pretty cool https://www.youtube.com/watch?v=wL9PcGu_xrA
03:10 AM XXCoder: solar tracker that uses solar panels as sensors AND power source.
04:03 AM Sabotend_ is now known as Sabotender
04:58 AM rmu: hmm. funny thing. automatic toolchanger. seems i get some errors from checking the pocket where to put a tool while generating previews of programs.
05:13 AM nkp216_: Has anyone already tried this at work?
05:14 AM nkp216_: (increase in the number of tools to 256)
05:14 AM nkp216_: https://forum.linuxcnc.org/38-general-linuxcnc-questions/29620-limit-to-number-of-tools-in-tool-table?start=20#120935
05:15 AM XXCoder: supported tools # is all way to 99999
05:15 AM XXCoder: BUT only 56 tools in tools table
05:15 AM XXCoder: of whatever number its set to
05:16 AM XXCoder: I run machines at work that has 250 tools so yeah lol
05:16 AM XXCoder: theres one with 500 tools but never ran that one
05:19 AM nkp216_: EMC machines??
05:19 AM XXCoder: nah company machines
05:19 AM XXCoder: like I said tool table limition is 56 entries
05:23 AM nkp216_: question about patch :
05:23 AM nkp216_: https://github.com/LinuxCNC/linuxcnc/issues/411
05:25 AM XXCoder: looks like quite stright change
05:25 AM XXCoder: sql idea seems interesting
05:25 AM XXCoder: too bad while I can program i have lost most of skills
05:26 AM nkp216_: I tried it and it works (emс changes the tool on the command T250 M6)
05:26 AM XXCoder: you can use any tool number up to 99999
05:26 AM XXCoder: but try add more tools till you go past 56 tools
05:29 AM nkp216_: I now have 250 tools in the table
05:29 AM XXCoder: nice
05:45 AM rmu: M73 in remapped g-code also seems to do unwanted stuff while preview-generation
05:45 AM rmu: i get some strange "F1,0M4 unknown character used" errors
05:51 AM nkp216_: comma vs point ?
05:51 AM gloops: great, made a nice little replacement tension roller for the dryer, fits works perfect - press button to test - fine, but the heating element arced out and went up in glowing ashes
05:52 AM XXCoder: localizaion problem maybe yeah
05:52 AM gloops: luckily they are only £15 lol
05:52 AM XXCoder: hey gloops ! check out video I made https://youtu.be/jTdDBzkMwVQ
05:54 AM gloops: looks like you got the hang of that XXCoder
05:54 AM XXCoder: yep
05:54 AM XXCoder: i also finished cleaning up the vismach file
05:54 AM XXCoder: so its now very readable tutorial machine
05:54 AM XXCoder: problem is im not sure where to add and type out on wiki.
05:56 AM gloops: well once youve got the knowledge plenty of time to sort out a tutorial
05:56 AM XXCoder: yeah
05:56 AM XXCoder: too bad jt is on vacation lol
05:58 AM XXCoder: I even made nice ascii tree on how parts of vismach is connected together into machine
05:58 AM gloops: there have been people in here asking about this
05:58 AM XXCoder: really?
05:59 AM gloops: yeah im pretty sure, in fact wasnt unreal asking about it a while ago
06:01 AM XXCoder: well hopefully my tutorial will end up being useful
06:01 AM XXCoder: only blank spot is work
06:01 AM XXCoder: it may be because it is not fully defined and used on linuxcnc side also?
06:07 AM gloops: ive never looked into it tbh
06:07 AM XXCoder: work object is just a mystery
06:07 AM XXCoder: all uses i see is just work = Capture()
06:08 AM XXCoder: then making it part of model
06:08 AM XXCoder: in my case its point on top of x table, at center
06:19 AM rmu: nkp216_: M73 should reset some settings like G90/G91, Feedrate etc... to the values they had before calling an o subroutine
06:20 AM rmu: so the comma it tries to set in F1,0 is probably self-generated
06:21 AM rmu: real error message: M7x: restore_settings failed executing: ' F1,0': Bad character ',' used
06:21 AM rmu: I wouldn't be surprised if this is a locale issue... somehow reminds me
06:22 AM XXCoder: yeah change to .
06:23 AM rmu: wischelstudio used to (only sometimes) put version numbers of project XML files through localisation and changed '.' to ',' and vice versa. fun when using source control
06:24 AM rmu: XXCoder: I can't change that, because linuxcnc saves those values upon M73 and should restore them automatically. restore fails. but only while generating the preview. program runs fine.
06:25 AM XXCoder: bleh
07:16 AM weenerdog: howdy
07:32 AM JT-Shop: morning
07:32 AM XXCoder: hey JT-Shop
07:33 AM XXCoder: check the video out https://youtu.be/jTdDBzkMwVQ
07:35 AM JT-Shop: looks like you got that sorted out
07:35 AM XXCoder: yeah
07:35 AM XXCoder: the vismach file is full of comments and details
07:36 AM XXCoder: but I dont really want to write wiki on it
07:36 AM XXCoder: wnna do it? all I ask is don't change machine name lol
07:37 AM XXCoder: or point out where page I can start writeu[
07:38 AM JT-Shop: ok rolfman
07:38 AM XXCoder: lol
07:40 AM JT-Shop: still trying to connect to my raspberry pi 3b with the ethernet cable lol
07:41 AM XXCoder: whats issue wit it?
07:41 AM methods_: did you try plugging it in?
07:42 AM JT-Shop: I want to ssh into it but can't seem to get it to connect like the internet said I could
07:42 AM XXCoder: hmm is rspi using same subnet as yours?
07:44 AM JT-Shop: hmm dunno
07:46 AM JT-Shop: hmm I think I got it
07:46 AM JT-Shop: https://raspberrypi.stackexchange.com/questions/30144/connect-raspberry-pi-to-pc-ubuntu-with-ethernet
07:48 AM XXCoder: nice
07:48 AM JT-Shop: whoop I'm in
07:48 AM XXCoder: where should I write my guide and stuff in wiki?
07:48 AM XXCoder: way to go. whats you do?
07:48 AM JT-Shop: wiki is pretty lame and outdated IMHO
07:49 AM JT-Shop: it should be in the docs how you did it
07:49 AM XXCoder: yeah not sure how to add
07:49 AM XXCoder: rolfmill vismach file is extremely detailed and commented
07:49 AM JT-Shop: you give me the information and it gets added by magic
07:53 AM XXCoder: okay though testing something to make sure first
07:53 AM JT-Shop: crap I forgot to copy my notes on ssfh...
07:54 AM XXCoder: I changed my mind and made tool appear right away with t(number)m6
07:55 AM XXCoder: need to call g43h(number) to set tooltip so it draws from tip
07:55 AM XXCoder: just like real machine, if you forget that it will crash
07:55 AM XXCoder: ie stove tool though table or dont even reach part, in whatever direction incorrect set length is lol
07:56 AM XXCoder: ok how do you want to get 3 files? rolfmill, rolfmill.hal and rolfmill.ini
07:56 AM weenerdog: cool paintjob on that mill man.
07:56 AM XXCoder: I want to add those 3 files to linuxcnc distro too
07:57 AM XXCoder: weenerdog: thanks lol
07:57 AM weenerdog: say you got it unfucked?
07:57 AM XXCoder: yep!
07:57 AM weenerdog: shweet
07:58 AM weenerdog: that last 100 yards of a project can be a humnogger
07:58 AM XXCoder: its like having blocked door to across kitchen so just go downstairs, go across it, go up another stairs and go in kitchen other way
07:58 AM XXCoder: its complex way to do it but works fine
07:58 AM XXCoder: side benefit is tool object updates instantly with tNm6
08:03 AM XXCoder: JT-Shop: sent
08:03 AM JT-Shop: ok, I need to setup email on this laptop lol
08:04 AM XXCoder: ok will wait though need sleep soon
08:04 AM weenerdog: choo a vampire?
08:05 AM XXCoder: lol
08:06 AM * JT-Shop tries to remember the password lol
08:07 AM XXCoder: its password12456not7
08:07 AM JT-Shop: more like @j5m^4u<.t6}9*+q2)&^
08:08 AM XXCoder: lol
08:08 AM weenerdog: i hate the new time. the day daylight savings time ended, i cut firewood all day and was wiped out, so 8:30pm i just had nothing left and went to bed. my last thought was "you know you're going to be basically at 7:30 right?"
08:08 AM XXCoder: I usr password manager awesome
08:08 AM weenerdog: since then, boom, wide awake 0400 every morning
08:08 AM * JT-Shop is wide away at 4am anyway and had all his firewood done long before winter sets in
08:09 AM XXCoder: no wood to do here
08:12 AM rmu: JT-Shop: do you know pwgen? generates memorizable passwords
08:12 AM weenerdog: i didn't cut a single load wearing more than a tshirt
08:13 AM JT-Shop: never used pwgen but I wrote a password generator to generate difficult to guess passwords
08:13 AM weenerdog: i just use my dog or girlfriend's name lol
08:16 AM XXCoder: JT-Shop: check out the fancy tree I made lol
08:17 AM XXCoder: very easy to spot, its in concept of machine design section
08:21 AM XXCoder: so what ya think so far?
08:24 AM XXCoder: oops line 193 error...
08:25 AM XXCoder: # now define collection of ybase and xbase. change it to # now define collection of ybase and xassembly.
08:25 AM XXCoder: somehow missed it with bunch of proof checkjs
08:27 AM gloops: damn missed the diy shop, needed some threaded bar
08:29 AM JT-Shop: just got back from the shower looking now
08:30 AM XXCoder: you would need to fix line 193 minor error but may confuse someone
08:31 AM JT-Shop: got it
08:32 AM JT-Shop: BTW you can surround lots of text with """ bunch of comments over several lines """
08:32 AM XXCoder: oh didnt know about triple doubkle quotes
08:33 AM XXCoder: eh its fine
08:33 AM XXCoder: what ya think of comments so far?
08:33 AM JT-Shop: nice, love lots of comments
08:34 AM JT-Shop: I thought I had the damn touch pad turned off
08:34 AM XXCoder: its santized lol most of comments were rougher but essentally same, but there was bunch of "what the heck does this do?"
08:34 AM XXCoder: and some obslete comments from what I misunderstood stuff, etc
08:35 AM XXCoder: code I dummied out and such was also removed as it dont seem nesscary now
08:35 AM XXCoder: most strange code is tool length and diameter update, as it incluydes in itself entire vismach so it can modify itself
08:36 AM XXCoder: nesscary since it have to change one part shape
08:36 AM XXCoder: thats why that section is far more comments than code lol
08:37 AM JT-Shop: the comments are great and will make adding useful info to the docs very easy for me thanks for the help
08:37 AM XXCoder: no problem!
08:37 AM XXCoder: only unclear spot is work
08:38 AM JT-Shop: the tree is a very good visual on how it fits together
08:38 AM XXCoder: I think linuxcnc dont add anything to do that
08:38 AM JT-Shop: if you make any changes just email it to me again
08:38 AM XXCoder: ok
08:38 AM XXCoder: doubtful as its been heavily reviewed bunch of times
08:39 AM XXCoder: literally only one word was wrong lol (ignoring my ugly grammar errors)
08:41 AM XXCoder: is the column box comment clear?
08:41 AM XXCoder: that one I wondered
08:42 AM JT-Shop: # column, attached to base on side. < this section?
08:42 AM XXCoder: line 139
08:43 AM JT-Shop: other than a word spelled wrong it makes sense to me
08:43 AM XXCoder: ah y one. oh well lol
08:44 AM JT-Shop: I always type a while then fix the spellos lol
08:46 AM XXCoder: hope its all clear so far
08:47 AM JT-Shop: looks good to me so far, we will be out all day check back in this evening
08:47 AM XXCoder: have fun :) going to bed
08:47 AM JT-Shop: night
10:20 AM _abc_: Hello, does anyone have a DIN number for a flanged ball bearing as used in some repraps? I need it for something else though.
10:20 AM Tom_L: what's the number on the seal?
10:21 AM _abc_: I don't have it, if that's for me Tom_L
10:21 AM Tom_L: what size bearing?
10:21 AM _abc_: I need the generic part number because the catalog of my supplier has no pics
10:21 AM Tom_L: id od width
10:21 AM _abc_: Does not matter, I'll figure out the rest from the context. I just need a DIN number for it. Like 626 etc
10:22 AM Tom_L: 608zz
10:22 AM _abc_: 608ZZ is not a flanged type. I assume the suffix adds the flange. Not sure.
10:23 AM _abc_: Also should be 4 or 5 digit for extras like that imo
10:23 AM Tom_L: https://www.vxb.com/
10:23 AM Tom_L: they have pics
10:23 AM _abc_: looking
10:37 AM JT-Shop: morning Tom_L
10:40 AM Tom_L: what's up?
10:41 AM JT-Shop: heading to branson for the day
10:41 AM Tom_L: chill moved in last night 26
11:00 AM _abc_: So anyway the nomenclature has a "R". Like "608 R". Also "608VV" brings up v-grooved one etc
11:00 AM _abc_: Thanks
11:07 AM Deejay: re
02:01 PM gloops: what HP is this motor anybody? https://www.ebay.co.uk/itm/Brook-crompton-Electric-motor-old-But-Working-signal-phase-240v/202444689476?
02:01 PM gloops: 1.5 i think
02:06 PM MarcelineVQ: mmm, does that say 11amps? 11 amps at 240v = 2640w 1 kw = 1.34102 hp 2.64kw = 3.54hp
02:06 PM MarcelineVQ: But uhm, those are just numbers, maybe motors have more to them than that
02:08 PM rmu: gloops: this motor has about 2kW
02:09 PM rmu: a bit on the high side for single phase ac induction "steinmetz" motor
02:10 PM rmu: IMHO
02:11 PM gloops: whats the wo 1500 represent?
02:12 PM gloops: the seller reckons 3hp - thats a lot for domestic 240 supply
02:12 PM MarcelineVQ: but in line with the plate, 220V@11A is 3.2hp
02:14 PM MarcelineVQ: mind you, 220V@1,1A is 0.3hp so, depends on how readable that is :>
02:14 PM pcw_home: a 1.5 HP motor 220V is about 10A
02:14 PM pcw_home: (due to power factor)
02:15 PM MarcelineVQ: so there is more to motors, thank you pcw_home
02:16 PM gloops: suppose ill have to go and have a look, it says 10 inch long - seems small for 3hp
02:17 PM pcw_home: There are good charts for this like: https://www.engineeringtoolbox.com/elctrical-motor-full-load-current-d_1499.html
02:17 PM MarcelineVQ: *bookmarks*
02:22 PM rmu: https://www.js-technik.de/media/image/ca/08/40/ml-daten-zeichnung.jpg
02:23 PM MarcelineVQ: gloops: note that given the latest info that's a 1.5hp motor
02:24 PM gloops: lol, see intuition of a non electrician
02:24 PM gloops: thats about what i want anyway, thanks all
02:26 PM gloops: hes also selling a tody looking little lathe, but i wont even think about looking at that
02:26 PM gloops: tidy
02:27 PM rmu: i crashed my ATC
02:27 PM rmu: damn
02:27 PM gloops: any damage?
02:28 PM rmu: 30mm dia steel rod is bent
02:28 PM gloops: ahh
02:28 PM rmu: could be worse
02:28 PM gloops: something else will be bent then
02:29 PM rmu: no, the y axis went into it with G0... nothing bent there
02:29 PM rmu: just a small ding in the paint
02:30 PM rmu: that's a heavy 100kg aluminium part
02:30 PM gloops: should be ok then
02:31 PM rmu: i was surprised what kind of forces these servos can develop...
02:32 PM gloops: i dont have those problems with my chinese steppers, anything hits anything i just hear a clacking sound
02:41 PM Loetmichel: rmu: i once miscalculate the travel on a 500kg rotating grinding table with a 3kw ac servo...
02:41 PM Loetmichel: moved ~2" to far...
02:42 PM Loetmichel: the end stops that were fixed to the linear rails with 2 M8 8.8 screws each flew across the shop and embedded themselves in the brick wall across.
02:42 PM Loetmichel: THAT was scary
02:46 PM rmu: M8 against 3kW sounds unfair
02:48 PM rmu: i was lucky because the servo controller has kind of a velocity-dependant torque limit
02:58 PM renesis: isnt that just like, motors?
02:58 PM renesis: or you can set a map or something
02:58 PM renesis: guys my linuxcnc is ancient af, why should i upgrade?
03:00 PM gloops: is the machine working ok?
03:01 PM renesis: ya, taig stepper, 1/4 blown up xylotex, same axis gui setup, very vanilla, for prob 5 years?
03:02 PM gloops: well i dont know why you would upgrade if the old version isnt a restriction on anything
03:02 PM rmu: never run a changing system
03:02 PM renesis: yeah i was just asking because maybe a reason
03:02 PM gloops: could stick another hard drive in with new version of linuxcnc and set it up alongside the old one
03:02 PM renesis: i didnt know axis was python, i should dig into that, maybe learn something
03:05 PM renesis: gloops: yeah, but its kind of a random junker dell, i dont really want to open it up
03:05 PM renesis: i guess i could stick a usb dvd drive on it and run a livecd
03:06 PM gloops: my linuxcnc PCs have been £10 ers
03:07 PM renesis: looked on craigslist, called and asked if the shit has a parallel port
03:08 PM renesis: i had a little mini mobo atom pc with reg size atx PSU, sexy little lian li case, but it died :(
03:09 PM renesis: have better lucky with junker pc
03:09 PM renesis: *luck
03:09 PM gloops: we have a big car boot sale near me every sunday, they more or less give old pcs and bits away
03:09 PM renesis: that sounds useful
03:10 PM gloops: not good for my hoarding tendencies though lol
03:11 PM renesis: i should throw some shit out
03:27 PM Rab: renesis, you can just run LunixCNC from a flash drive.
03:34 PM renesis: i thought about that, but who knows with the dinosaur bios
03:35 PM renesis: is not broken, tho, and its offline so i dont care about ancient lunix
03:35 PM renesis: i sneaker net gcode onto it
04:25 PM Deejay: gn8
04:26 PM Tom_L: later
05:23 PM XXCoder: hey all
05:28 PM infornography: lo
05:43 PM JT-Shop: hola
05:44 PM XXCoder: yo
05:54 PM JT-Shop: you start your work week tonight?
07:43 PM * JT-Shop gives up trying to find a simple led indicator for pyqt4...
08:01 PM renesis: jt-shop: cant you just use a red dot?
08:02 PM JT-Shop: where is a red dot?
08:04 PM JT-Shop: well I have a few red dots but they are all on guns
08:39 PM XXCoder: JT-Shop: tomorrow yeah monday
08:40 PM XXCoder: 3 day work this week
08:45 PM XXCoder: jthornton: you in? heh
