12:27 AM miss0r2: mornin'
12:31 AM miss0r2 is now known as miss0r
01:55 AM Deejay: moin
04:59 AM fragalot: 'ello
05:06 AM jthornton: morning
05:18 AM Tom_itx: morning
05:25 AM jthornton: dang firefox updated gotta reboot now
05:28 AM XXCoder: gonna love updates
05:30 AM XXCoder: wb
05:32 AM jthornton: crap I left the weather underground page on yesterday
05:32 AM jthornton: it used up .4GB I think
05:34 AM jthornton: the weekend looks nice for the Spyder Palooza ride
05:35 AM XXCoder: I wonder if theres POTS isp there at your location
05:35 AM jthornton: what's that?
05:35 AM XXCoder: plain old telephone system
05:36 AM XXCoder: of course issue with that ios you need hardline phone first. which is quite expensive now
05:36 AM jthornton: yea no hard line anymore
05:41 AM XXCoder: heh I wouldnt live anywhere remote enough npot to have high speed unlimited bandwidth
05:52 AM * Deejay has fibre :)
06:00 AM * jthornton has obama fiber 1.6 miles from his house that is not connected to anything
06:06 AM XXCoder: gonna love dark fibers. there is TONS around usa, and most of em opredate obama
06:06 AM XXCoder: there was nice goverment program to add lots more fibers, and isps added em
06:06 AM XXCoder: they refused to use em though
06:07 AM jthornton: yea they ran fiber along a lot of roads in Missouri
06:11 AM XXCoder: fun. too bad they seem to refuse to use em
06:12 AM XXCoder: that would solve any bandwith issues easily! it would have lowered high bandwidth prices by a lot so probably why,.
06:26 AM Deejay: hm
06:30 AM XXCoder: man. https://earth.nullschool.net/#current/wind/surface/level/orthographic=-86.61,35.93,1160
06:54 AM Loetmichel: XXCoder:... and then there are german companys that first hit a main natural gas pipe with their "earth rocket" while putting empty tubes for glass fibre in the ground and then need one year to fix all the fibre joints in the city because they used a wrong glue the first time making those joints and THEN have to pull 4 times a 4 fibre bundle into the tube to our country to have finally ONE
06:54 AM Loetmichel: of the 4 fibres working and not broken...
06:54 AM Loetmichel: ... to work with pros for once!
06:55 AM XXCoder: hey only difference between newbies and pros is pros make bigger issues! lol
06:57 AM Loetmichel: my look when the annoyed man from the utility rang at the company door and said "we have to switch off the gas for a few days, some idiot of the internet company managed to penetrate the main gas pipe with his earth rocket..." ... priceless :-)
06:58 AM XXCoder: lol
06:58 AM XXCoder: earth rocket sounds so awesome I don't wanna know what real one does.
06:58 AM XXCoder: ;)
06:59 AM XXCoder: wow off I go to bed. time to dream of earth rocket
06:59 AM Loetmichel: its a horizontal ram that can pull a 1" plastc tube about 300ft thru the dirt without digging
07:00 AM Loetmichel: sounds like those "pillar rams" you hear sometimes and works similarily
07:01 AM Loetmichel: long hygraulic cylinder with a hardened steel tip, behind it a big weight in the cylinder that gets rammed hydraulically into the ti´p about twice a second to drive it forward
07:01 AM Loetmichel: and it pulls hydraulic lines and the plastic tube behind it
07:03 AM Loetmichel: you basically dig a hole to the right depth, insert the ram horizntally, start the hydraulics, guide it into the dirt and dig a second hole up to 300 ft away and hope it emerges there
07:31 AM jthornton: morning
07:31 AM jthornton: ok got hexchat working lol
07:56 AM Jin|away is now known as Jin^eLD
08:16 AM miss0r: mornin jt
08:43 AM henn1nk: hello all. i am trying to write some ngc routines.. but linuxcnc says, that it can't find #<_ini[tool_change]z>.. any idea why? my ini file: https://github.com/HendrikRoth/hildegard/blob/tool-change/hildegard.ini#L78 and the routine: https://github.com/HendrikRoth/hildegard/blob/tool-change/macros/tool_change.ngc#L10
08:52 AM jthornton: henn1nk: what version of LinuxCNC are you using?
08:52 AM henn1nk: jthornton: scratch
08:53 AM jthornton: 2.7 or 2.8 (master)?
08:53 AM henn1nk: 2.8.8
08:54 AM henn1nk: 2.8.8*
08:54 AM henn1nk: 2.8.0*
08:54 AM henn1nk: 2.8.0-pre1 to be exact :)
08:54 AM jthornton: I don't see #<_ini in the named parameters list
08:54 AM jthornton: http://linuxcnc.org/docs/devel/html/gcode/overview.html#gcode:predefined-named-parameters
08:55 AM henn1nk: oh
08:55 AM henn1nk: so maybe deprecated
08:56 AM jthornton: not in 2.7 either
08:56 AM henn1nk: i know for example probe_screen is using _ini
08:56 AM henn1nk: https://github.com/verser-git/probe_screen/blob/master/macros/yplus.ngc#L14
08:57 AM henn1nk: and gmoccappy either: https://github.com/LinuxCNC/linuxcnc/blob/master/configs/sim/gmoccapy/macros/change.ngc#L21
08:57 AM henn1nk: :-/
08:57 AM jthornton: hmmm I don't have LinuxCNC installed on this pc yet just installed a new OS
08:58 AM jthornton: but wait
08:59 AM henn1nk: ok
08:59 AM jthornton: henn1nk: http://linuxcnc.org/docs/devel/html/config/ini-config.html#_rs274ngc_section
08:59 AM jthornton: FEATURES is required for that to work
09:00 AM jthornton: http://linuxcnc.org/docs/devel/html/remap/remap.html#remap:ini-features
09:01 AM henn1nk: yepp works, thank you!
09:02 AM jthornton: yw
09:02 AM henn1nk: forgot this on my demo maschine :-)
09:03 AM * jthornton hopes he can remember to add a link to the system parameters section for this
09:04 AM henn1nk: yeah would be great :)
09:04 AM henn1nk: have to leave, thank you again
09:05 AM jthornton: your welcome
09:23 AM pcw_home: Largest airplane in the world left Oakland today (its been there a couple of days)
09:24 AM pcw_home: Antonov 225 (only 1 exists)
09:58 AM Tom_itx: the dreamlifter is pretty amazing
09:58 AM sync: pcw_home: yeah the thing is hueg
09:58 AM Tom_itx is now known as Tom_L
09:58 AM sync: I've seen it a few times
09:59 AM sync: and its little sisters
10:00 AM Tom_L: few places those can go
10:03 AM sync: well, basically being a .mil transporter for bad strips they can go almost anywhere
10:23 AM JT-Shop: there's 1 1/2 Antonov 225s
10:24 AM JT-Shop: https://www.cnn.com/travel/article/antonov-an-225-kiev-ukraine/index.html
10:24 AM Tom_L: saw the dreamlifter at the airshow over the weekend. they wouldn't let us inside though
11:09 AM robotustra: afternoon
11:10 AM robotustra: have a question, anybody used linuxcncrsh?
11:10 AM robotustra: is it possible to get a RPMs of spindle which were set by S command?
11:11 AM robotustra: I cen get only spindle override
11:13 AM * robotustra works on cnc layout https://imgur.com/i0Jw9gH
11:14 AM robotustra: do I need DTG button at all?
11:17 AM Tom_L: i've got spindle speed displayed on mine
11:17 AM robotustra: how do you get it?
11:18 AM robotustra: is it possible to get it on simulator?
11:19 AM JT-Shop: the only mention in the docs is "linuxcncrsh - a telnet based user interface which allows commands to be sent to LinuxCNC from remote computers"
11:20 AM Tom_L: motion.spindle-speed-out
11:20 AM JT-Shop: hmm linuxcncrsh does have a man page
11:20 AM robotustra: I use linuxcncrsh to control lcnc machine from my gui, but this rsh permit to get spindle override only
11:20 AM robotustra: it has
11:20 AM robotustra: http://linuxcnc.org/docs/html/man/man1/linuxcncrsh.1.html
11:22 AM JT-Shop: man page says "All features of LinuxCNC are available via the linuxcncrsh interface"
11:22 AM robotustra: I attached already 40% of my gui to lcnc and can do some stuff already
11:22 AM robotustra: now will work on opengl view
11:23 AM robotustra: to view the path
11:24 AM robotustra: I can run my gui in parallel with axis or gmoccapy
11:25 AM robotustra: have to do gl view
11:25 AM JT-Shop: it's Saturday here so nap time for me
11:25 AM robotustra: haha
11:26 AM robotustra: it's sunday at my place
11:27 AM robotustra: I have like 3 sundays at row
11:28 AM beachbumpete1: What planets are you on its Thursday on mine ;)
11:29 AM robotustra: thursday also can be a sunday
11:31 AM robotustra: Tom_L, what gui do you use and how do you attach this pin?
11:31 AM robotustra: .hal?
11:31 AM Tom_L: axis
11:32 AM Tom_L: net spindle-vel-cmd motion.spindle-speed-out => abs.0.in pid.0.command
11:32 AM robotustra: do you read encoder or set value by S command?
11:32 AM Tom_L: it does several things
11:32 AM Tom_L: encoder
11:32 AM robotustra: ok
11:36 AM gregcnc: https://youtu.be/s2yIMJ4iayg?t=1m2s
12:00 PM Rab: Anybody followed the Defense Distributed/Ghost Gunner drama of the past few years?
12:01 PM Rab: I'm not super into guns (and 3D printed guns seem like a joke), but I'm fascinated by how they seem to have productized a 3D mill, in the USA, for a $1200 price point.
12:02 PM Rab: (Even if its work envelope is limited to an AR lower.)
12:03 PM Rab: And most of all I'm fascinated by the little belt-driven ER spindle in these pix: https://www.freedomsphoenix.com/Media/173426-2015-03-31-03-31-15-daniel-dabek-mp3-video-bonus-loaded.htm
12:03 PM Rab: Seems like it's commodity chinesium, and it must be for the price, but I haven't seen that particular thing before.
12:03 PM Rab: I guess I could email the dude and get put on a watchlist.
12:10 PM robotustra: what's the point to build cnc dedicated to AR production?
12:11 PM Rab: Weapons proliferation, I believe.
12:12 PM robotustra: for what?
12:12 PM Rab: It uses gcode or 3D printed tracing jigs, so it can machine other stuff too...1911 lowers I believe.
12:12 PM robotustra: the weapon is freely sold in US
12:13 PM robotustra: Rab, did you ever hold in hands lower receiver of 1911?
12:13 PM Rab: I believe it's a challenge to free speech, copyright, and gun control laws...I don't fully understand the rationale.
12:13 PM Rab: robotustra, never.
12:13 PM robotustra: I did
12:13 PM robotustra: do you know how they are produced?
12:13 PM Rab: Casting?
12:13 PM robotustra: yes
12:13 PM robotustra: mine is
12:14 PM robotustra: as well as many parts like trigger, disconnector, hummer, etc
12:14 PM robotustra: it's much cheaper to cast than to mill
12:15 PM Rab: There's a market in USA for partial lowers. A finished lower is considered a gun and requires a serial number, an unfinished lower is just a piece of metal and easier to buy/sell.
12:15 PM robotustra: I see the only point to produce guns - if you are inventor and designing a prototype weapon
12:15 PM robotustra: I know anout 80% lowers
12:15 PM Rab: So people will buy "80%" finished lowers and mill the final features, which the Ghost Gunner is intended to facilitate.
12:16 PM robotustra: another question
12:16 PM robotustra: can you shoot this ghost gun freely?
12:16 PM Rab: They claimed to be able to mill complete lowers from aluminum stock, but they're using 1/8" tooling and I guess that would be a time-consuming and failure-prone process.
12:17 PM Rab: I believe so, subject to the restrictions of your municipality, but I don't know for sure.
12:17 PM robotustra: no, 1/8 is fast enough even to mill large pockets
12:17 PM robotustra: let's say I want to shoot my ghost gun
12:18 PM robotustra: can I go and buy ammo without licence?
12:18 PM robotustra: I doubt so
12:18 PM robotustra: in canada you can't buy ammo without permition, so the ghost gun will be useless
12:19 PM Rab: But not very deep pockets, unless you have a lot of stick-out which makes the tool fragile.
12:19 PM robotustra: how many guns do you need?
12:19 PM robotustra: 1? 2?
12:19 PM robotustra: 10?
12:20 PM Rab: robotustra, no license here: http://lawcenter.giffords.org/ammunition-regulation-in-texas/
12:20 PM robotustra: what do you need a gun?
12:20 PM Rab: robotustra, I need 0 guns, and I'm not making an argument for the existence of the Ghost Gunner.
12:20 PM robotustra: texas is not a whole US
12:22 PM Rab: But if you're alarmed by its existance, then I think it's done its job. The point seems to be provocation.
12:26 PM gregcnc: provocation?
12:26 PM robotustra: Are you alarmed by existance of guns?
12:26 PM Rab: robotustra, no.
12:27 PM robotustra: well, I think gun topic is closed
12:28 PM Rab: Good job opening and closing that topic. My intent was to discuss the particulars of the CNC machine.
12:29 PM robotustra: :)
12:29 PM robotustra: I mean the gun topic is good for #guns channel
12:30 PM robotustra: I also like to talk about guns, but it's a specific subject for canada, because it's much different from usa
12:30 PM robotustra: in laws and regulations
12:30 PM robotustra: Rab, do you want to make AR lower on custom build cnc machine?
12:31 PM Rab: robotustra, negative.
12:32 PM robotustra: do you have cnc machine?
12:32 PM Rab: robotustra, affirmative.
12:32 PM robotustra: custom built?
12:32 PM Rab: robotustra, affirmative.
12:32 PM robotustra: what controller do you use on it?
12:32 PM robotustra: SW
12:32 PM gregcnc: what's interesting about the spindle?
12:33 PM robotustra: Rab, lcnc?
12:33 PM Rab: I'm embarassed to admit that I use a very old version of FlashCut CNC, because it matches the hardware controller I have.
12:33 PM robotustra: ok, so you want to upgrade it to something newer?
12:34 PM robotustra: Rab, it means that you build your machine long time ago?
12:34 PM Rab: gregcnc, it's surely cheaper than a motorized spindle, and one would be able to use a variety of motors. If it's available, I'd be interested in buying one.
12:35 PM Rab: robotustra, I do want to build a new machine, although the current machine (and FlashCut) are working well.
12:35 PM robotustra: good
12:35 PM robotustra: I'm building new machine too
12:36 PM Rab: gregcnc, I've already built a belt-driven ER11 spindle, but partly because I didn't know of one available for purchase (for cheap).
12:36 PM gregcnc: sounds like the current spindle was an upgrade so you can probably buy one
12:36 PM Rab: I'm about to build a bigger one with a brushless electric chainsaw motor.
12:37 PM Rab: Probably ER16.
12:37 PM gregcnc: ER11
12:37 PM robotustra: I have 1.5kW chinesium spindle with ER11 and VFD
12:37 PM robotustra: works ok for me
12:38 PM robotustra: max diameter shank is 7mm, but my main cutter is 1/8"
12:38 PM Rab: robotustra, those work for a lot of people, but I'm reluctant to spend the money. Some of them are really poorly-made and you can't exactly send them back.
12:39 PM robotustra: what's your budget?
12:39 PM robotustra: do you count your manufacturing time?
12:39 PM Rab: robotustra, as low as possible, just for fun.
12:39 PM robotustra: vfd+spindle ~ 300$
12:40 PM Rab: I do production for profit on my current machine, so it would pay off, but minimal budget is a neat optimization constraint.
12:40 PM gregcnc: I think Taig and Sherline have ER16 spindles
12:44 PM gregcnc: https://www.sherline.com/product/30111-er-16-headstock/
01:05 PM fragalot: miss0r|office: this thing is the most frustrating thing in the world. https://photos.app.goo.gl/cb3HcusbH1wNM83k6
01:07 PM fragalot: miss0r|office: also, I meant to send this one first :P https://photos.app.goo.gl/ZxYWzePt9kii5xg8A
01:31 PM gloops: 10000 lines left to finish this cut
01:32 PM gregcnc: what caused the lost steps yesterday?
01:32 PM gloops: junk catching cables
01:32 PM gloops: well, im assuming thats what it was, no repeat since i moved the junk
01:36 PM gloops: had the great idea of using under the table for storage, last week i was working on a vertical surface to be fitted to the machine frame underneath
01:36 PM gloops: of course - threw a load of boxes of junk to the back to get access - was all piled up were cables drag
01:38 PM gregcnc: time for some cable chains
01:46 PM diverdude: Hi, i have 2 stepper motors driving a table in X and Y direction. I am trying to write a homing routine based on 2 switches. It seems to work nicely, however when i have reached the 2 switces i want to go a few steps back to let go of the switches again. This seems to fail. For some reason when i set the motors to go in opposite direction they dont move at all. What am I doing wrong? Here is my small routine: https://paste.ubuntu.c
01:47 PM diverdude: https://paste.ubuntu.com/p/Pk9k2rr8JN/
01:48 PM Tom_L: diverdude check my config. i do the same thing for homing
01:48 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/configs/NEW_MILL/
01:48 PM Tom_L: .ini
02:04 PM Rab: https://www.youtube.com/watch?v=DLEx5eId2N8
02:05 PM Rab: I can only assume the motor's for testing.
02:06 PM fragalot: love the banana jacks in that screw connection thing
02:07 PM Rab: It's interesting that some of these DIY spindles are so short and stubby. I guess the design was bounded by the 100mm or 150mm length of the ER32 tool holder. It seems like a longer spindle would have less radial play at the end of the tool.
02:08 PM gregcnc: most smaller spindles have a back to back bearing pair right at the nose
02:09 PM gregcnc: at ER32 size i'd just go for BT30
02:34 PM miss0r|office: fragalot: haha
02:34 PM miss0r|office: fragalot: but it looks like you nailed it ;)
02:34 PM fragalot: eventually
02:34 PM miss0r|office: I am having some strange issues of my own. I haven't played around with linux for a long time.
02:35 PM miss0r|office: One thing that is pissing me off at the moment, is the implementation of systemd, to handle startup scripts ect.
02:35 PM miss0r|office: I simply _cannot_ make it run my touchscreen driver script at boot.
02:35 PM fragalot: :/
02:35 PM miss0r|office: when the machine is started, I can do a 'service touchscreen start' and it works perfectly.
02:35 PM miss0r|office: But I cannot for the life of me figure out what I am doing wrong :D
02:36 PM miss0r|office: I have been looking at it sinde 19:30 or something like that
02:36 PM fragalot: missing dependency on boot?
02:36 PM miss0r|office: two hours of trying to auto load a script, will make anyone mad :D
02:36 PM miss0r|office: Doubtfull. I have tried all runlevels
02:36 PM JT-Shop: yea that kind of stuff can drive you nuts
02:36 PM Jin^eLD: miss0r: *hint* man chkconfig for non systemd services
02:37 PM JT-Shop: hmmm my raspberry pi I had to add a service to run my script at boot up that controls the chicken coop
02:37 PM miss0r|office: Jin^eLD: ha.. yeah :)
02:40 PM miss0r|office: apparently chkconfig is not standard on the debian stretch
02:40 PM Jin^eLD: doh..
02:41 PM miss0r|office: its this new systemd stuff.
02:41 PM Jin^eLD: debian... hmm.. update-rc.d ?
02:41 PM Jin^eLD: systemd should provide init compatibility for legacy stuff
02:41 PM Jin^eLD: or work along with it side by side if needed
02:41 PM miss0r|office: last time I did anything with debian I could just add my executable script to /etc/init.d/ and run update-rc.d [name] defaults
02:41 PM miss0r|office: and all would be well
02:41 PM Jin^eLD: but yeah, for debian its update-rc.d I think
02:42 PM miss0r|office: now - not so much
02:42 PM miss0r|office: I mean, update-rc.d is there - it is used by systemd. But adding it as such, does not make it execute at startup, apparently
02:43 PM gloops: keeping her indoors off my back https://www.youtube.com/watch?v=zE_AGP75en8&feature=youtu.be
02:44 PM Jin^eLD: well, worst case you could write your own system.d module, I never did that but I think it should not be a too big deal for shell scripts
02:44 PM miss0r|office: Its not.. But it is about 6x more comlicated(annoying) than just using 'ye oldie method
02:44 PM JT-Shop: miss0r|office: what version of debian?
02:45 PM miss0r|office: jt-shop: Debian stretch
02:46 PM JT-Shop: https://ritsch.io/2017/08/02/execute-script-at-linux-startup.html
02:46 PM Jin^eLD: miss0r: well that of course, I hate systemd as well, but what can one do...
02:48 PM miss0r|office: JT-Shop: well. Theres no rc.local file 'out'a the box' in debian stretch
02:48 PM JT-Shop: https://absolute.hosting/index.php?rp=/knowledgebase/19/Enable-rclocal-startup-file-on-Debian-9-Stretch.html
02:49 PM miss0r|office: I'd need to add it to systemd firstly
02:49 PM JT-Shop: a better one
02:49 PM JT-Shop: this cat knows that rc.local is not there by default
02:49 PM miss0r|office: so it would seem
02:49 PM JT-Shop: what a pia lol
02:51 PM JT-Shop: that last page is similar to what I had to do on the raspberry pi
03:03 PM miss0r|office: That was the solution. :)
03:03 PM miss0r|office: Next step: mount it all in a case, and get going on the mesa config :]
03:07 PM Jin^eLD is now known as Jin|away
03:15 PM miss0r|office: I'm off. Have a good one
03:16 PM XXCoder: het JT-Shop did you solve that axis and axes thing?
03:24 PM robotustra: what is rs274?
03:24 PM Rab: robotustra, g-code.
03:25 PM Roguish: https://ws680.nist.gov/publication/get_pdf.cfm?pub_id=823374
03:25 PM Rab: With a few differences relevant to LinuxCNC, it appears: http://linuxcnc.org/docs/html/gcode/rs274ngc.html
03:28 PM robotustra: it looks like lcnc gcode interpreter understands parameters?
03:28 PM robotustra: and python input
03:28 PM robotustra: ?
03:29 PM robotustra: can somebody tell me how linuxcnc spells to opengl window?
03:31 PM robotustra: it looks like interpreter loads the g-code file and does it draw opengl widget directly?
03:32 PM JT-Shop: XXCoder: yes
03:32 PM XXCoder: awesome. whats you do? :)
03:33 PM JT-Shop: http://dpaste.com/05AYMQG
03:34 PM JT-Shop: the format specifier should have been #011b
03:34 PM JT-Shop: so the last row lined up
03:34 PM XXCoder: man thats very short code. youre god
03:35 PM XXCoder: just do a quick bit walk
03:35 PM JT-Shop: hazzy: figured it out then I added the print so one could understand what was going on under the hood
03:36 PM XXCoder: you probably could unroll the loop
03:36 PM XXCoder: so it has big O of 1
03:37 PM JT-Shop: how's that?
03:39 PM XXCoder: http://dpaste.com/18NQ0AZ
03:40 PM XXCoder: its good thing to do if it gets called a LOT.
03:40 PM XXCoder: otherwise not really worth it
03:41 PM fragalot: XXCoder: what you want to do is use the native assembly instructions to do that task for you.
03:41 PM XXCoder: fun with asm for all!
03:44 PM XXCoder: honestly smart compilers does unroll if its small enough fixed integer loops
03:44 PM XXCoder: but python no idea
03:44 PM XXCoder: anyway off to work I go
03:44 PM XXCoder: JT-Shop: congats though :)
03:44 PM fragalot: python typically doesn't
03:44 PM fragalot: and is terrible with loops in terms of speed
03:44 PM fragalot: even worse if you print in them
03:44 PM XXCoder: ecch. laters :)
03:46 PM JT-Shop: there is 9 axes so how is that better?
03:46 PM JT-Shop: have fun at work
03:46 PM fragalot: if it is something you do A LOT at a high frequency, it could be faster to use 9 if statements than a single loop
03:47 PM fragalot: (note: COULD. depends on many other factors to say at which point it becomes faster or slower)
03:47 PM JT-Shop: ah ok, in this case it matters not one whit it's only executed once on start up but thanks for the info I'll remember that for sure
03:47 PM fragalot: yea no point in going bonkers optimising for speed there :)
03:47 PM JT-Shop: I prefer short easy to read code when I can
03:47 PM robotustra: if you are doing something at high frequency it's better not to yse python
03:47 PM fragalot: agreed.
03:47 PM robotustra: use*
03:47 PM fragalot: robotustra: xD
03:48 PM JT-Shop: yea the dxf to g code I used golang and it's pretty fast
03:50 PM robotustra: if I'm going to use my gui remotely probably I have to built in rs274 interpreter in it...
04:00 PM Deejay: gn8
04:00 PM robotustra: gn9
04:04 PM robotustra: does linuxcnc support canonical interface?
04:05 PM robotustra: is any modern CAM can export canonical g-code?
04:07 PM JT-Shop: aww they are gone if you read back axes = [(i) for i in range(9)if mask & (1<<i)]

04:29 PM zeeshan: hi
04:30 PM zeeshan: hope you guys near the coast are bracing@!
04:30 PM gregcnc: zee is that big llathe still a lump in the garage?
04:30 PM zeeshan: yes
04:30 PM zeeshan: planning to work on it soon
04:30 PM zeeshan: winter project
04:30 PM zeeshan: i got a bunch of parts for it
04:31 PM zeeshan: i'm going to be using the yaskawa sigma 7 drives on it
04:32 PM zeeshan: whats new with you
04:34 PM gregcnc: not much, making some parts
04:34 PM zeeshan: pix
04:36 PM JT-Shop: hey zeeshan
04:36 PM zeeshan: my milling machine finally died off
04:37 PM zeeshan: it wont release tools cause it's pissing fluid out of the horizontal spindles' clamping unit
04:37 PM zeeshan: hi jt
04:37 PM zeeshan: so i'm now trying to figure out how to pull the horizontal spindle :)
04:37 PM gregcnc: oh no
04:37 PM JT-Shop: needs some TLC
04:37 PM zeeshan: https://i.ebayimg.com/00/s/NTc2WDEwMjQ=/z/bKwAAOSwKFBZqEg8/$_72.JPG
04:37 PM zeeshan: i think the thing on the left is the clamping unit
04:37 PM zeeshan: looks quite different from the vertical clamping unit that i rebuilt a while back
04:55 PM zeeshan: https://photos.app.goo.gl/ThEWfkAxcFM2Dv2N8
04:55 PM zeeshan: i removed the 6 bolts
04:55 PM zeeshan: its not clear how this thing comes out lol
04:55 PM zeeshan: i've never pulled a horizontal spindle before!
04:56 PM zeeshan: https://photos.app.goo.gl/HuRH4ui8QTyYBGMy6
04:56 PM zeeshan: looks like there is a plate to access the gear train
04:56 PM gregcnc: no exploder views?
04:56 PM zeeshan: nope
04:56 PM zeeshan: never had manuals for this thing
04:56 PM Loetmichel: maaan, thats a "for the looks" scraping if i ever have seen one...
04:56 PM Loetmichel: to your problem: probably from behind
04:57 PM zeeshan: i figure most horizontal spindles come out in a similar way?
04:57 PM zeeshan: https://i.ebayimg.com/00/s/NTc2WDEwMjQ=/z/bKwAAOSwKFBZqEg8/$_72.JPG
04:58 PM zeeshan: i don't see what keeps this whole spindle housing in axially
04:59 PM gregcnc: i forget what machine that is
05:01 PM zeeshan: mikron wf21c
05:03 PM zeeshan: andypugh: nice job on the high speed spindle
05:03 PM andypugh: Thanks
05:05 PM zeeshan: i'll never buy another machine without manuals again!
05:05 PM zeeshan: makes it such a pain in the ass.
05:14 PM _unreal_: damn!!! screwed up one of my orderes from amazon. I got an hdmi to 90 degree mini hdmi not hdmi to 90 degree hdmi cable #$@#$
05:14 PM _unreal_: just ordered the correct adapter.
05:14 PM _unreal_: sucks faster to order the right plug end then it is to deal with a return
05:14 PM _unreal_: luckly its only $6
05:50 PM rene_dev_: andypugh you have a lathe in the living room, I now have a drillpress in the kitchen.
05:51 PM andypugh: Perfect for coring apples.
05:51 PM rene_dev_: however, I also have a pick and place machine in the kitchen.
05:51 PM rene_dev_: its in pieces, in the ultrasound
05:59 PM _unreal_: rene-dev, and you are also single
06:01 PM skunkworks: andypugh: awesome video..
06:01 PM skunkworks: andypugh: how come you don't use the touch probe?
06:01 PM Rab: Anybody have a favored technique for determining the resonant frequency of a machine?
06:01 PM skunkworks: big hammer?
06:02 PM skunkworks: ;)
06:02 PM andypugh: The touch probe (at the time) wasn’t compatible with the drawbar of the horizontal spindle
06:02 PM skunkworks: ah
06:02 PM * skunkworks couldn't live without his touch probe...
06:02 PM andypugh: I found 10 Zeiss touch probes in a skip recently, I now have one for each spindle.
06:03 PM skunkworks: nice skip...
06:08 PM andypugh: I was a bit surprised.
06:15 PM rene_dev_: andypugh why cant I find your external offset lathe video?
06:15 PM rene_dev_: I want to try that on my lathe, its working now.
06:15 PM rene_dev_: _unreal_ I am now, yes.
06:16 PM andypugh: https://www.youtube.com/watch?v=z6dK41_usfQ
06:21 PM skunkworks: re-assembling.. http://electronicsam.com/images/greenmachine/20180911_175630.jpg
06:36 PM _unreal_: call it a hunch
06:38 PM _unreal_: My goal for tonight, try to get the sla7024...... wtf why didnt any one tell me I should have drilled holes and mounted that PSU to the LCD BACK back mount panel first
06:38 PM _unreal_: skunkworks, where you cleaning?
06:53 PM skunkworks: _unreal_: lots of lining stuff up correctly
06:53 PM skunkworks: the ballscrews where so far out of parallel it was scary
06:54 PM skunkworks: and added a z column spacer
06:55 PM skunkworks: http://electronicsam.com/images/greenmachine/20180823_225905.jpg
06:57 PM skunkworks: rerunning oil lines.. (no flow regulators/one way valves)
06:58 PM skunkworks: http://electronicsam.com/images/greenmachine/20180904_190133.jpg
06:58 PM skunkworks: keeps me out of trouble
06:59 PM Roguish: skunkworks: what is the basic machine make/model?
07:02 PM skunkworks: Roguish: it is basically a prototype of the tormach 440
07:02 PM Roguish: how'd you end up with thata?
07:02 PM skunkworks: http://bbs.homeshopmachinist.net/threads/76679-Small-mill-project-(SMP)?highlight=small+mill+project
07:02 PM skunkworks: Roguish: for some work I did..
07:03 PM skunkworks: needless to say - they didn't go with this supplier.. :)
07:03 PM skunkworks: it will be a solid machine when done. just needed a bit of tlc
07:04 PM Roguish: looks nice and stout. like it.
07:05 PM skunkworks: the sliding surfaces all seem great
09:34 PM _unreal_: There and with that 90% of my computer for my cnc machine has been put together
09:35 PM _unreal_: funny how its just a touch screen and tinker boared
09:35 PM _unreal_: board
09:35 PM _unreal_: I just finished loading most of the wires to it. except for the one that I'm waiting on the replacement cable. My stupid :(
09:35 PM _unreal_: Then I can plug the video in
