12:03 AM XXCoder: yo
12:07 AM infonograph: ello
12:10 AM miss0r: yo
12:10 AM pink_vampire: hi
12:10 AM pink_vampire: how do i find it the program is finished?
12:11 AM XXCoder: on other machines it usually turns off green light and program returns to start
12:11 AM XXCoder: not too sure on linuxcnc
12:11 AM pink_vampire: I have the stacklight controller
12:12 AM miss0r: did it say M30 on the screen?
12:12 AM XXCoder: yeah I remember that. still think thats cool!
12:12 AM pink_vampire: miss0r: i mean like a hal signal
12:12 AM miss0r: no idea :)
12:12 AM pink_vampire: like "motion.in-position" that indicate if the machine is moving
12:13 AM XXCoder: ahh HAL dunno
12:13 AM XXCoder: evenually jt will come in. I guess in couple hours
12:13 AM pink_vampire: where i can see a list of them?
12:16 AM fragalot: pink_vampire: http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Halui
12:16 AM fragalot: check the -program section
12:16 AM miss0r: fragalot: My package is still in belgium :) it seems it has moved one city over :D
12:17 AM fragalot: miss0r: :D
12:17 AM pink_vampire: halui.program.is-running
12:17 AM fragalot: pink_vampire: I think you may want is-idle
12:18 AM pink_vampire: i want to get the BEEP only if the program is done, not if i killed it
12:20 AM fragalot: use an M code for that then
12:20 AM fragalot: https://forum.linuxcnc.org/forum/49-basic-configuration/24901-using-beep-with-linuxcnc-m-code
12:20 AM pink_vampire: beep is use the sound card
12:21 AM pink_vampire: it's like to use the mist relay
12:21 AM pink_vampire: but this is use something in your code to tell you the code is done,
12:21 AM pink_vampire: i want something from linux cnc
12:21 AM fragalot: you're shit out of luck then
12:22 AM Wolf__: put a staples “that was easy” buttons on the table and have the end mill press it at end of cycle
12:22 AM pink_vampire: LOLLLLLLLLLLL
12:22 AM fragalot: the M code way is how i've done it on fanuc, siemens, and taiwanese machines for years
12:23 AM pink_vampire: i did it the same way in the mach3 years ago
12:23 AM pink_vampire: but i think in linux cnc that you have all those signals, maybe there is a better way
12:24 AM * fragalot => off to work
12:50 AM pink_vampire: where do i save the M code files?
12:51 AM pink_vampire: in the user_m_path?
01:04 AM pink_vampire: http://linuxcnc.org/docs/html/gcode/m-code.html#mcode:m100-m199
01:05 AM pink_vampire: the M110 Example file don't work.
01:06 AM pink_vampire: i tried it in the terminal (with my username and ta correct picture name) and it work,
01:06 AM pink_vampire: but as M code, I'm getting "unknown M code used M110"
01:08 AM pink_vampire: what does that mean "Note After creating a new M1nn file you must restart the GUI so it is aware of the new file, otherwise you will get an Unkown m code error."
01:08 AM Wolf__: close linux cnc and reopen
01:09 AM pink_vampire: I did it, same error, there is no special way to "restart the GUI"?
01:11 AM Wolf__: no idea then
01:11 AM pink_vampire: do i need to declare the Mcode somewhere ?
01:15 AM pink_vampire: The file is not an executable file
01:15 AM pink_vampire: mmm
01:15 AM pink_vampire: lets see
01:18 AM pink_vampire: chmod +x M110, then close and open linux cnc , solved the issue
02:12 AM Deejay: moin
02:14 AM pink_vampire: hi Deejay
02:15 AM Deejay: hi pink
02:15 AM Wolf__: morning
02:15 AM pink_vampire: how are you doing?
02:16 AM selroc: hello
02:18 AM pink_vampire: selroc: !
02:19 AM selroc: how is going ?
02:19 AM pink_vampire: the machine blink on movement
02:20 AM pink_vampire: melody beeps on finish cut
02:20 AM pink_vampire: and now i'm working on the probing
02:21 AM selroc: nice
02:23 AM pink_vampire: it is not that easy with the probe
02:26 AM pink_vampire: it is not that easy with the probe
02:30 AM Wolf__: weird, my probe beeps on contact
02:34 AM pink_vampire: i'm getting an error that tell me the pin motion.probe-input is already in use
02:34 AM Wolf__: actually its the probe interface box that beeps
02:35 AM pink_vampire: i know i can do that
02:36 AM pink_vampire: but i want to work with the linux cnc signals
02:37 AM pink_vampire: I have that in the code
02:37 AM pink_vampire: net my-sigin1 or2.0.in0 <= parport.1.pin-10-in-not
02:37 AM pink_vampire: net my-sigin2 or2.0.in1 <= parport.1.pin-11-in
02:37 AM pink_vampire: net both-on motion.probe-input <= or2.0.out
02:37 AM pink_vampire: can you help me understand why i did that?
02:38 AM pink_vampire: "my-signal" is the net name?
02:38 AM pink_vampire: so each net has a name?
02:43 AM selroc: what is the motion control hardware ?
02:48 AM pink_vampire: selroc: what do you mean?
02:48 AM pink_vampire: it is 2 parallel ports
02:48 AM pink_vampire: I'm getting 2 signals pin 10 and pin 11, they go in to "OR" and become my Probe input
02:50 AM pink_vampire: but i need to duplicate it somehow
02:55 AM XXCoder: cant you create another variable and point it to same pin #?'
03:11 AM rmu|w: pink_vampire: do you need the output of the "or" block to go out of the parport?
04:00 AM pink_vampire: I have no idea
04:01 AM pink_vampire: i have 2 devices that make signals for the "probing" in linux cnc.
04:02 AM pink_vampire: the first one is the "probe" and the second is the tool setter
04:02 AM pink_vampire: the probe is N.C the tool setter is N.O,
04:03 AM pink_vampire: this is why i need the "OR" and invert one of those pins.
04:03 AM pink_vampire: after the "OR" they used as my "motion.probe-input" pin in hal.
04:03 AM pink_vampire: ------------------------
04:05 AM pink_vampire: now i want to forward the "motion.probe-input" signal to " parport.1.pin-17-out"
04:06 AM pink_vampire: but I'm getting an error that "motion.probe-input" is already in use
04:06 AM pink_vampire: rmu|w: ^ XXCoder ^
04:06 AM XXCoder: interesting
04:07 AM XXCoder: what line does it define motion.probe-input ?
04:07 AM pink_vampire: those 3 lines
04:08 AM XXCoder: unfortunately I dont know hal
04:08 AM XXCoder: fortunately jt should be coming in soon
04:09 AM pink_vampire: https://i.imgur.com/iwqnTFS.png
04:10 AM pink_vampire: this is the code that i was trying to add
04:10 AM pink_vampire: https://i.imgur.com/gWar8GI.png
04:11 AM XXCoder: add this line below last line in first picture
04:11 AM XXCoder: net both-on motion.probe-input2 <= or2.0.out
04:12 AM XXCoder: and add 2 to line that causes already used error
04:14 AM pink_vampire: https://i.imgur.com/dzsqBib.png
04:14 AM pink_vampire: like that?
04:14 AM XXCoder: though is it line 31 that caused error?
04:14 AM XXCoder: or other place
04:14 AM pink_vampire: i have no idea
04:14 AM pink_vampire: lets see
04:15 AM XXCoder: look if motion.probe-input is defined elsewhere
04:15 AM pink_vampire: i'm trying with the line you told me to add
04:15 AM pink_vampire: no
04:15 AM XXCoder: where is motion.probe-input used anyway
04:16 AM pink_vampire: i'm not sure
04:16 AM pink_vampire: the error is on line 32
04:17 AM pink_vampire: motion.probe-input2 dose not exist
04:17 AM XXCoder: okay remove that line I'm olviously misunderstanding how that HAL lines work
04:18 AM XXCoder: I dont know where motion.probe-input is defined
04:18 AM pink_vampire: I think it is defined here
04:18 AM pink_vampire: net both-on motion.probe-input <= or2.0.out
04:19 AM pink_vampire: without your line i'm getting the error:
04:19 AM XXCoder: apparently not if it complains 2 one doesnt exist, if its being defined it should not complain its nonexistant
04:20 AM pink_vampire: Pin 'motion.probe-input' was already linked to signal 'both-on'
04:20 AM pink_vampire: line 62
04:20 AM pink_vampire: this is line 62
04:20 AM pink_vampire: net probebeep => motion.probe-input
04:21 AM XXCoder: looks like can't link to output twice
04:21 AM pink_vampire: i removed line 62, and linux cnc opened.
04:22 AM XXCoder: where is both-on defined?
04:22 AM pink_vampire: what about to connect a signal to output?
04:22 AM pink_vampire: only in line 31
04:22 AM XXCoder: once you link motion.probe-input, you cant link it again
04:23 AM pink_vampire: i'm trying to change line 62
04:23 AM pink_vampire: from
04:23 AM pink_vampire: net probebeep => motion.probe-input
04:23 AM pink_vampire: to
04:24 AM pink_vampire: net probebeep => both-on
04:24 AM XXCoder: did it work?
04:24 AM pink_vampire: error
04:24 AM pink_vampire: line 62..
04:25 AM pink_vampire: pin 'both-on' dose not exist
04:25 AM pink_vampire: maybe to use or2.0.out instead of both-on?
04:26 AM XXCoder: I don't know enough unfortunately
04:27 AM pink_vampire: error: Pin 'or2.0.out' was already linked to signal 'both-on'
04:29 AM pink_vampire: soved!
04:29 AM pink_vampire: solved!
04:30 AM XXCoder: yay! what dd you do?
04:30 AM pink_vampire: line 61
04:30 AM pink_vampire: i changed it from
04:30 AM pink_vampire: net probebeep => parport.1.pin-17-out
04:30 AM pink_vampire: to
04:30 AM pink_vampire: net both-on => parport.1.pin-17-out
04:31 AM XXCoder: interesting. does it work as expected to work?
04:31 AM pink_vampire: and delete line 60
04:31 AM pink_vampire: #setp parport.1.pin-17-out-invert true
04:31 AM pink_vampire: yes
04:31 AM XXCoder: I suspect both-on is a output so it makes sense to link it that way you did
04:31 AM XXCoder: linking to input doesnt work
04:32 AM pink_vampire: the probe make the stack light to change from green to red and green and it also beep
04:32 AM XXCoder: <output result> => <output pin>
04:33 AM pink_vampire: more than 2 years i'm waiting to this moment
04:33 AM rmu|w: sorry, was AFK
04:33 AM rmu|w: so in hal, you have the concept of "signals"
04:34 AM rmu|w: a pin can only ever be connected to one signal
04:34 AM rmu|w: not two
04:34 AM pink_vampire: and signals?
04:36 AM pink_vampire: rmu|w: can you connect signal more then one time?
04:39 AM rmu|w: you can connect multiple pins to one signal
04:39 AM rmu|w: but not the other way round
04:39 AM rmu|w: so you can not connect one pin to multiple signals
04:40 AM rmu|w: oh just saw that you solved the problem, so nevermind ;)
04:40 AM pink_vampire: rmu|w: until next time LOL
04:41 AM pink_vampire: it is soooo fun to hear the BEEP
04:42 AM XXCoder: you have actual light signal system im so jelious
04:42 AM XXCoder: honestly I want hand pendant way more than lights
04:45 AM bazhang is now known as Guest14256
04:46 AM pink_vampire: I have a the stacklight controller that have 6 inputs, and according to them it power the red/yellow/green/buzzer
04:51 AM pink_vampire: if the E-stop is engaged - RED, servos and other high voltage activated - GREEN, servos are moving (even if jog) - BLINK GREEN, probe / tool setter engaged RED + GREEN + BEEP, finish job - RED GREEN alternating and melody, error signal like over heating - YELLOW flashing fast + ALARM
04:52 AM pink_vampire: XXCoder: ^
04:52 AM XXCoder: interesting
04:53 AM XXCoder: machines at work usually has this as standard: yellow - idle. Blinking green - program is running but on m0 stop or paused. steady green is running
04:54 AM pink_vampire: XXCoder: mine is better :)
04:54 AM pink_vampire: I LOVE the beep on the probing!!! LOVE IT
04:54 AM XXCoder: I do recommand switch green states, steady as running, flashing as m0 or paused
04:55 AM XXCoder: besides that whatever. to me flashing means it needs attention
04:55 AM pink_vampire: this is why is that, clean chips, and stuff like that
04:57 AM pink_vampire: on industrial machine there is high pressure coolant and other stuff so you can basically go sleep while it running
04:57 AM XXCoder: kind of. some machines dont work that well
04:58 AM pink_vampire: compare to DIY benchtop mill ...
04:58 AM XXCoder: some machines like that damned okuma have to check everything over before start it because it will error out if change from tool 1 to tool 1 or any same tool again, so in order to make it not error out there must be no tool change
04:58 AM XXCoder: if I change to chuck then check stuff and doesn't change it back...
04:58 AM XXCoder: it happened once, I destroyed that chuck cat50
04:58 AM XXCoder: it cost over $1000
04:59 AM XXCoder: most machines isnt that dumb but yeah
04:59 AM pink_vampire: I don't have tool changer here, I barely have tools
04:59 AM XXCoder: yeah very different scale machine eh
05:00 AM XXCoder: my home machine dont even have any tool holder, just er11 directly on spindle
05:00 AM pink_vampire: I made all that G codes and make 1 part..
05:00 AM XXCoder: so I cant "kinda" automate tool changes
05:01 AM XXCoder: yours use toolholder right? so you can measure all tools lengths and just manually swap em as needed?
05:01 AM pink_vampire: so far it as very good day for me
05:02 AM pink_vampire: XXCoder: collets!!!
05:02 AM pink_vampire: the shorter the better
05:02 AM pink_vampire: and the HF use ER 11
05:02 AM XXCoder: I mean something like cat40, cat50
05:02 AM XXCoder: your machine, if it had em, would be very small like cat20
05:03 AM XXCoder: cat 40 and 50 https://www.practicalmachinist.com/vb/attachments/f21/96974d1389999621-cat-40-versus-cat-50-a-cat4050.jpg
05:03 AM pink_vampire: i think toormac offer bt30
05:04 AM XXCoder: bt30 https://ae01.alicdn.com/kf/HTB1771ygVOWBuNjy0Fiq6xFxVXaU/High-Precise-font-b-BT30-b-font-ER20A-70L-CNC-Milling-Chuck-font-b-Tool-b.jpg_220x220q90.jpg
05:04 AM XXCoder: that looks same as robo machine ones
05:04 AM XXCoder: its not nearly as tiny as one found in office mill at work lol
05:04 AM pink_vampire: XXCoder: the only reason i want the low speed spindle is for tapping and facing, other wise the HF is amazing.
05:04 AM XXCoder: if its not holding tool, you could hide toolholder in hand
05:05 AM pink_vampire: for me, my go to endmills is the 1/8" and the 1/16"
05:05 AM XXCoder: nice
05:06 AM XXCoder: im not sure what sizes I would regularly use
05:06 AM pink_vampire: those are the ones that i'm using 99% of the time for milling.
05:06 AM XXCoder: I have few 6mm endmills and bunch of worn 1/16" ball endmills
05:06 AM XXCoder: worn compared to it was before but it can easly mill alum or wood whatever
05:07 AM XXCoder: got 1/16s from work, it ran on incel metal 30 parts then worn lol
05:07 AM pink_vampire: for facing I have the fly cutter ith the insert lathe tool from harbor freight
05:07 AM XXCoder: whats size of flycutter
05:07 AM pink_vampire: small, it's go in the low speed spindle.
05:07 AM pink_vampire: about 2"
05:08 AM XXCoder: cool :)
05:08 AM XXCoder: 2" is standard facemill size at work also
05:08 AM XXCoder: most times if need facemill its 2"
05:08 AM XXCoder: only rarely do we use larger ones
05:09 AM XXCoder: largest one I know is 10", its so large that if person forgot to remove it, it would break toolchanger and tools in corsel
05:09 AM pink_vampire: I'm taking a pic for you
05:09 AM XXCoder: I cant lift that monster also. well I can but very barely.
05:12 AM pink_vampire: https://i.imgur.com/OIRiWum.png
05:12 AM pink_vampire: the face mill, and the finish I'm getting with it
05:13 AM XXCoder: wow actual flycutter
05:13 AM pink_vampire: fly cutter****
05:13 AM XXCoder: we dont use em at work at all
05:13 AM pink_vampire: it is facing operation..
05:13 AM XXCoder: yeah far better finish than facemill
05:14 AM XXCoder: but we use facemills because it lasts a lot better
05:14 AM XXCoder: https://i.ebayimg.com/images/g/dXoAAOSwcB5ZJfLj/s-l300.jpg typical one
05:14 AM pink_vampire: for less then 10$..or so..
05:14 AM XXCoder: sometimes 3, 4 or 6 inserts for 2"
05:15 AM pink_vampire: I can't drive it with my spindle.
05:15 AM XXCoder: maybe not? I dont know your machine abilities
05:15 AM pink_vampire: about 1HP spindle..
05:16 AM pink_vampire: i have no idea about the servo.. maybe less? because the 1:1 but more speed?
05:17 AM pink_vampire: also I have no idea how to drive it.
05:17 AM XXCoder: theres special toolholder for it, if yours dont use any you cant drive it at all
05:17 AM pink_vampire: XXCoder: i mean how to drive the servo spindle
05:18 AM XXCoder: oh! dunno
05:18 AM pink_vampire: I have dual 72V 10A power supply
05:18 AM pink_vampire: and now it X+y on 10A and the Z on the other 10A
05:19 AM pink_vampire: maybe to add the spindle to the Z?
05:20 AM XXCoder: dunno
05:21 AM pink_vampire: me either..
05:21 AM pink_vampire: but we will see...
05:21 AM pink_vampire: I can't find my 10-32 tap!!
05:22 AM pink_vampire: WTF
05:22 AM MarcelineVQ: if you're anything like me you can't find it because you broke it and forgot to get a new one ;_:
05:23 AM XXCoder: lolk
05:23 AM pink_vampire: i van even find the drill for it
05:23 AM pink_vampire: but maybe i have an idea where it can be
05:24 AM pink_vampire: yeah! I found it
05:27 AM Tom_L: last place you put it right?
05:30 AM Tom_L: 72F Hi 79 and rain most of the week
05:30 AM XXCoder: Tom_L: nah its always at last place person looked. always.
05:32 AM jthornton: morning
05:32 AM Tom_L: morning jt
05:32 AM XXCoder: yo
05:42 AM rmu|w: lol. leak in ISS was caused by worked that drilled hole and patched it up instead of reporting it
05:42 AM XXCoder: yeah
05:42 AM XXCoder: someone is so in trouble
05:43 AM pink_vampire: hi jthornton
05:43 AM jthornton: hi pink_vampire
05:44 AM pink_vampire: do you know if linux cnc can support ridgid tap?
05:44 AM jthornton: of course
05:44 AM rmu|w: pink_vampire: it can
05:45 AM jthornton: http://gnipsel.com/images/bp-knee-mill/encoder07.jpg
05:45 AM pink_vampire: I have a step / dir servo. that is going to be my spindle
05:46 AM Tom_L: pink_vampire sure it can
05:46 AM XXCoder: jthornton: is that tool hold and release servo?
05:46 AM XXCoder: or spindle encoder
05:46 AM jthornton: spindle encoder for tapping
05:46 AM XXCoder: nice
05:47 AM jthornton: http://gnipsel.com/shop/bp1/bp1.xhtml
05:47 AM pink_vampire: but how I configure the servo to work as my spindle?
05:47 AM Tom_L: even on a sherline: https://www.youtube.com/watch?v=g99lUtjLfMU
05:47 AM jthornton: thanks that was fun to make
05:48 AM pink_vampire: but the tapping is like a C axis?
05:48 AM Tom_L: G33 iirc
05:49 AM Tom_L: G33.1
05:49 AM jthornton: tapping is Z coordinated with spindle rpm and pitch
05:49 AM pink_vampire: how do you make M6 thread?
05:49 AM Tom_L: how far in z does it move in 1 turn?
05:50 AM pink_vampire: 1mm for 1 rev
05:50 AM jthornton: what ever the pitch is
05:50 AM pink_vampire: 1mm Z per 1 rev in the spindle
05:50 AM jthornton: pink_vampire: http://linuxcnc.org/docs/2.7/html/gcode/g-code.html#gcode:g33.1
05:50 AM Tom_L: that's the K value
05:51 AM XXCoder: why why why do people always out in rapid in z and either x or y at same time?
05:52 AM Tom_L: position the XY first
05:52 AM XXCoder: no, z when tool is still down in part :)
05:53 AM pink_vampire: Tom_L: but ho i configure the servo to act as spindle??
05:53 AM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/configs/NEW_MILL/new_mill.hal
05:53 AM Tom_L: it's in there somewhere
05:54 AM Tom_L: net spindle-velocity hm2_[HOSTMOT2](BOARD).0.encoder.01.velocity => near.0.in2 scale.0.in motion.spindle-speed-in
05:54 AM Tom_L: net spindle-index-enable motion.spindle-index-enable <=> hm2_[HOSTMOT2](BOARD).0.encoder.01.index-enable
05:54 AM Tom_L: i believe
05:55 AM pink_vampire: your encoder as connected to linux cnc?
05:55 AM pink_vampire: was*
05:55 AM Tom_L: motion.spindle-speed-in
05:55 AM Tom_L: yes
05:56 AM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/new_pulleys/new_pulley_mounted2.jpg
05:56 AM pink_vampire: in my case it is basically very fast C axis
05:56 AM Tom_L: thanks to an old printer :D
05:57 AM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/new_pulleys/spindle_enc1.jpg
05:57 AM pink_vampire: it is very similar setup,
05:57 AM Tom_L: updated it to that
05:57 AM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/new_pulleys/spindle_enc6.jpg
05:57 AM Tom_L: 500cpr iirc
06:02 AM miss0r: I am living in a shipment black hole at the moment :S
06:02 AM pink_vampire: miss0r: what do you mean?
06:02 AM miss0r: I have 6 deliveries hanging outwhere somewhere, all quite delayed
06:02 AM * miss0r is going nuts waiting :)
06:03 AM miss0r: One; A set of angle blocks sent from the UK got lost in mail. So the seller sent me another one with TNT express, whom have not, apparently, lost it
06:03 AM miss0r: well, they don't quite know where it is atleast.
06:05 AM XXCoder: miss0r: deliveries go half the distance it traveled yeserday and again next day
06:05 AM XXCoder: so it takes a little while
06:06 AM miss0r: at that rate, it will never get here...asymptote
06:06 AM XXCoder: up to a point, then you could just step to slowly moving deliveryperson and just take it :)
06:07 AM miss0r: Also.. I've ordered some converters from bulgaria.. I realy hope they get here at some point :) I have some trust issues when it comes to that particular country...
06:12 AM miss0r: XXCoder: Sure.. but that could take forever.. close to anyway
06:12 AM XXCoder: lol yeah. halving gets it close to your home pretty fast
06:13 AM XXCoder: suppose new york to me, hmm lemme see map
06:13 AM XXCoder: lets see, first day its middle of usa
06:13 AM XXCoder: 3rd day its in washington state
06:14 AM XXCoder: 4th middle of washington
06:14 AM XXCoder: 5th day it finally crosses into west wa
06:14 AM XXCoder: 8th day it enters tacoma
06:15 AM XXCoder: 15th day its couple blocks away
06:15 AM miss0r: lol
06:15 AM XXCoder: I'd just walk across by then
06:16 AM miss0r: the tappinghead I sent fragalot yesterday, only moved one city over, here in Denmark
06:16 AM XXCoder: fromt of my house by 20th day
06:16 AM miss0r: so.. aehm.. They are *not even* moving the distance a day 'round 'ere
06:16 AM XXCoder: time length grows exponentally as person crosses my driveway
06:16 AM miss0r: hehe
06:17 AM miss0r: The scraper he sent me is still stuck in belgium. Even though it was sent friday
06:23 AM jthornton: miss0r: looks like your package cleared customs today
06:24 AM miss0r: jthornton: yeah. I had to call them about that, so they could sent me an invoice. But it should be out for delievery tomorrow or the day after
06:24 AM jthornton: cool
06:26 AM miss0r: I can't wait to get started with this. Perhaps I should start reding up on how the hell to program it with linuxcnc :)
06:26 AM * miss0r has no clue where to even start :D
06:26 AM miss0r: jthornton: Also; You mentioned running a latency test a machine with the linuxcnc liveCD. How do I go about that?
06:27 AM jthornton: http://linuxcnc.org/docs/2.7/html/getting-started/getting-linuxcnc.html#_download_the_image
06:28 AM miss0r: I've already downloaded the image. Haven't burned it to a CD yet, though.
06:28 AM flyback: eww cd
06:28 AM * flyback bites miss0r
06:28 AM miss0r: wtf! :D
06:29 AM jthornton: just boot from the cd and run the latency test or from the terminal you can run the latency-histogram
06:29 AM miss0r: Do I need a DVD to fit it? (I can't even remember the size)
06:29 AM flyback: oh you just mean installer
06:29 AM flyback: still you should use a flash drive or something
06:29 AM flyback: much eaiser :P
06:29 AM miss0r: heathen!
06:29 AM flyback: BMCC
06:29 AM miss0r: jthornton: What am I looking for in terms of results?
06:29 AM * flyback THROWS a canadian at miss0r
06:29 AM jthornton: yea the cd size days are long gone
06:30 AM miss0r: flyback: Now thats pretty offensive! What did that canadian ever do to you?! :)
06:30 AM miss0r: meh.. DVD it is then
06:31 AM flyback: tons of bad sci fi in the 90's
06:31 AM flyback: that's what canada did to me
06:32 AM flyback: and justin beiber and celine diod
06:32 AM miss0r: hehe
06:32 AM miss0r: Had you started with Justin Beiber, I would have accepted
06:32 AM miss0r: I like celine, though
06:33 AM miss0r: jthornton: But are these results even worth anything to me, when using servos?
06:35 AM jthornton: yea if you have terrible latency it can affect servos as well... still looking for the numbers that pcw gave me
06:36 AM jthornton: best to run the latency-histogram --no-base
06:36 AM miss0r: so to sum up our conversations from the past few weeks: No CPU throttle & a low jitter value is what I want?
06:38 AM jthornton: yea < 100,000 IRC is fine for jitter
06:38 AM miss0r: Excellent. I will go look for computer hardware soon (visiting my friends computer store)
06:41 AM flyback: I dunno why you guys don't combine a linux pc with some arduinos for cnc work
06:41 AM jthornton: CPU/network latency on Preempt-RT is affected more by CPU horsepower than RTAI so very low power CPUs
06:41 AM jthornton: Like the older Intel Atoms (D525 etc) that worked well with RTAI do not do well with Preempt-RT
06:41 AM flyback: let the arduinos handle the nanosecond timing of motors etc
06:41 AM jthornton: saw that from pcw on the forum
06:42 AM miss0r: jthornton: The network part would only be interresting to me, if I used the network based mesa units, correct?
06:42 AM jthornton: miss0r: that is the wrong link let me find the uspace one
06:43 AM jthornton: yea, I forget what did you order?
06:43 AM flyback: seriously mcu's are diry cheap
06:43 AM * flyback bites jthornton for good measure
06:44 AM miss0r: jthornton: 7i77-6i25 PLUG-N-GO KIT & 7i64
06:44 AM flyback: someone should write a slave libary for mcu's to work wiht linuxcnc
06:45 AM miss0r: flyback: Whynot you ? D:
06:45 AM jthornton: ok you can use the rtai cd then
06:45 AM flyback: im done
06:45 AM flyback: grandma is about to die and I am going to have to move so I am tossing half of my shit
06:45 AM flyback: i might decide I had enough of this planet after 44 yrs while I am at it
06:45 AM CaptHindsight: friends don't let friends use *duinos
06:45 AM jthornton: http://linuxcnc.org/dists/
06:45 AM flyback: doesn't have to be a duino
06:46 AM flyback: CaptCANUCK
06:46 AM miss0r: jthornton: It seems more and more apparent to me, that I know too little at this point: :)
06:46 AM CaptHindsight: yap yap yap yap
06:47 AM jthornton: are you getting a new motherboard or a used one?
06:47 AM miss0r: jthornton: I'm thinking a new one. I will go test a few different ones and find a suitable candidate
06:48 AM jthornton: ok, it's been a while since I looked for a motherboard
06:48 AM miss0r: also, can you link me to somewhere I can read about the different versions of the latest dist. I have no idea what rtai is
06:48 AM miss0r: I'll take notes of the ones I test, should anyone be interrested
06:49 AM jthornton: https://forum.linuxcnc.org/18-computer/33428-end-2017-pc-build-for-7i77-retrofit-which-motherboard-cpu-video-card
06:50 AM jthornton: if your doing software step generation you have to use rtai if your using a Mesa Ethernet card you have to use preempt
06:52 AM miss0r: jthornton: Correct me if I am wrong: But running servos, I will not be doing any stepping, software or hardware?
06:52 AM CaptHindsight: he's using a PCI/e FPGA
06:53 AM CaptHindsight: miss0r: just kill all the power management, speed stepping etc in the BIOS and run the latency test
06:53 AM CaptHindsight: not too big a deal...
06:53 AM miss0r: Indeed. I figured that part ;) I'll just quit asking questions in here, and dig into some manuals.
06:54 AM miss0r: I'll have plenty of questions to go 'round after I've started putting it together & have some programming of linuxcnc to do
06:55 AM jthornton: https://forum.linuxcnc.org/18-computer
06:55 AM jthornton: miss0r: right
06:57 AM XXCoder: flyback: sucks
06:58 AM XXCoder: CaptHindsight: I recall you told me there was 2 things to kill in bios, power management and something else
06:58 AM flyback: speedstep probably
07:02 AM Loetmichel: XXCoder: it usually doesent matter though
07:02 AM Loetmichel: the last few PCs i have set up with linuxCNC it made no difference at all if powermanagement and speedstep was on or off
07:03 AM Loetmichel: neither for latency nor for lost steps
07:03 AM XXCoder: interesting
07:04 AM Loetmichel: i know that some older IBM/lenovo notebooks had extremly nasty (NMI) power management interrupts that made them pretty much unusable for LinuxCNC on the LPT, but that was the last time i noticed any difference.
07:08 AM flyback: again why do we do this with pc's
07:09 AM flyback: use a pc for the brain the executive etc but have the actuators running mcu's with a rtos
07:09 AM flyback: pc
07:09 AM flyback: are not low latency and linux is not a rtos
07:09 AM flyback: this makes less sense than me trying to father children
07:10 AM SpeedEvil: Because meaningless semantic arguments are utterly pointless compared to what actually in fact works.
07:10 AM flyback: I trust you
07:11 AM Loetmichel: SpeedEvil: thank you
07:11 AM flyback: Loetmichel, BMCC
07:12 AM Loetmichel: If that is an insult: maybe try to use one that is understood worldwide next time.
07:15 AM XXCoder: best man caught cats
07:21 AM miss0r: jees. I leave you guys for 5 minuts to take a shit & this place turns into a war zone...
07:21 AM miss0r: okay... maybe 15 minuts. but still
07:22 AM Loetmichel: war zone?
07:22 AM Loetmichel: where?
07:23 AM rmu|w: this channel is stupid
07:23 AM miss0r: :]
07:24 AM miss0r: I'm somewhat falling in love with the idea of using a micro-itx motherboard(witheverything on there from factory).
07:24 AM miss0r: Alot of people are saying nice things about a few of'em on various linux cnc threads
07:43 AM miss0r: Can linuxCNC utilize more than one core? or would I just be wasting money, CPU wise?
07:44 AM flyback: miss0r, THERE IS also intel nuc
07:45 AM flyback: and several other nice single board computers
07:45 AM flyback: <rmu|w> this channel is stupid
07:45 AM flyback: and you are canadian
07:45 AM miss0r: Do you have any refrence how well they fare in the latency test?
07:45 AM flyback: no sorry :(
07:45 AM flyback: but some sbc's you can get with isa etc
07:46 AM flyback: I have a geode board with 2 lpt 4 com, 4 gpio and a isa slot
07:46 AM flyback: but linux takes 20 mins to boot from a live cd
07:46 AM flyback: it's not quick :/
07:46 AM miss0r: realy? ISA slot? :)
07:46 AM flyback: yeah
07:47 AM miss0r: Cute
07:47 AM flyback: they make some core2 etc boards with isa but I think it's a usb to isa bridge or a pci to isa bridge
07:47 AM flyback: the usb ones suck
07:47 AM miss0r: The issue with the NUCs are they they do not support PCIe
07:47 AM flyback: they are ok if you want to save a $10,000 SPECIALIZED card but blah
07:47 AM gregcnc: j1900 work well, i think it's what tormach is using these days
07:47 AM miss0r: The ones that i've found, anyway
07:47 AM flyback: what
07:47 AM flyback: nics are all pci-e
07:47 AM flyback: nucs
07:48 AM flyback: some have a slot you could run to a breakout board
07:48 AM miss0r: gregcnc: j1900... Searching
07:48 AM flyback: I wasn't bashing linux or using a pc for cnc
07:48 AM flyback: not at all
07:49 AM flyback: I was just saying if we are struggling to get sub nanosecond timing it might be easier to use a mcu per motor and that be slaved to a linuxcnc box
07:50 AM miss0r: gregcnc: I wonder if they are using celeron because it gives relatively good results at a cheap price, or because it is hands down the best. I'm guessing the first one
07:50 AM gregcnc: i think best is hard to quantify in our case
07:50 AM flyback: you guys probably want to disable spectre/meltdown fixes for cnc stuff
07:51 AM miss0r: gregcnc: sure. What are you running?
07:51 AM gregcnc: bahahaha, p3 900mhz 512mb ram
07:51 AM miss0r: Probally excellent for the job at hand :)
07:52 AM miss0r: I don't mind using old hardware for projects. But as I am already balls deep into spending money on this, I wouldn't want to cheap out when it comes to the computer hardware
07:54 AM gregcnc: my lathe build started with the same + mesa this time, might try an hp sff, 8100 i think. i tested it with Lcnc a while ago
07:54 AM miss0r: From what I read online HP machines usualy does not fare too well with linuxcnc
07:57 AM gregcnc: it varies, this box if the fan hits full speed, i get a 500us+ spike
07:58 AM miss0r: :]
07:58 AM gregcnc: this was recommended on lcnc forumshttps://www.gigabyte.com/au/Mini-PcBarebone/GB-BXBT-1900-rev-10#ov
07:58 AM gregcnc: https://www.gigabyte.com/au/Mini-PcBarebone/GB-BXBT-1900-rev-10#ov
07:59 AM flyback: miss0r, btw
07:59 AM flyback: check out the radio controlled car server power supply thread
07:59 AM flyback: they are dirt cheap or free
07:59 AM rmu|w: miss0r: maximal flexible architecture would be using mesa boards connected via ethernet
07:59 AM flyback: I have one it's 12 volts at 50 amps
07:59 AM flyback: err 60
08:00 AM flyback: and a small amount of 3.3v standby power
08:00 AM flyback: plus it has smbus so I can monitor load, temp etc
08:00 AM miss0r: gregcnc: The only annoying bart about that thing: no pcie opening in the box
08:00 AM flyback: those forums show you how to wire them to turn on etc without a server
08:00 AM miss0r: flyback: sure.. I have two 12v dc 236A PSUs on a shelf next to me
08:00 AM gregcnc: i think everyone using j1900 is using ethernet
08:01 AM miss0r: gregcnc: I felt more comfortable with using the pcie card :)
08:01 AM flyback: https://www.mouser.com/ProductDetail/Intel/BLKDE3815TYBE?qs=ui%252b2d9lVEI6fZKFwtxVVqQ%3D%3D&gclid=EAIaIQobChMIpceh47Oh3QIV0QOGCh2lfgUDEAQYASABEgKjP_D_BwE
08:01 AM flyback: not a bad price
08:01 AM miss0r: rmu|w: yeah. Perhaps that was the road I should've walked, in hinsight. but nevertheless, I didnt :)
08:02 AM miss0r: flyback: Not too bad no
08:02 AM flyback: ooo that one is dc input also
08:02 AM * flyback drools
08:02 AM miss0r: flyback: as oposed to the more common AC input ones?`:D
08:03 AM flyback: well no as oppsed to normal ac input psu connected to it
08:03 AM flyback: dc ones are nice for alt power projects or getting a dc output ups with a insanely long runtime
08:03 AM miss0r: I'm thinking I'll get a proper powerful one. And just feel the joy of a fast boot. :)
08:03 AM flyback: they make fast sbc's
08:04 AM flyback: advantech
08:04 AM flyback: soekris
08:04 AM * flyback thinks
08:04 AM flyback: supermicro (they may be going under)
08:04 AM flyback: alix
08:04 AM miss0r: that would make me sad. I've always liked their barebone servers
08:05 AM flyback: yeah we do too at work but they got delisted
08:05 AM flyback: I been waiting for a bios update for spectre/meltdown and it looks like they are in trouble
08:05 AM flyback: their web page keeps timing out etc
08:05 AM miss0r: jthornton: How many pci-lanes for that 6i25 require?
08:06 AM flyback: sorry
08:06 AM flyback: not alix
08:06 AM flyback: it's called pc engines
08:06 AM flyback: my bad
08:06 AM * flyback is going senile at 44
08:07 AM flyback: miss0r, https://www.pcengines.ch/pic/apu2c2_1.jpg
08:07 AM flyback: man staples had 120gb ssd's for $40
08:07 AM miss0r: looks cute
08:07 AM flyback: I missed it
08:08 AM flyback: oh the pc engines do coreboot
08:08 AM flyback: nice
08:09 AM flyback: I partially ported coreboot to that geode
08:09 AM flyback: but it's all wrong interrupts etc but it did boot linux
08:09 AM flyback: something the stock bios wouldn't do cause it set dma wrong etc
08:09 AM flyback: I need to put a bios socket on it so I can keep testing code
08:10 AM flyback: mabye one of those 2 to 1 switcher hacks
08:10 AM flyback: so I can swap between 2 bios chips
08:10 AM flyback: with coreboot you can hard wire it always to be to serial console no matter what
08:10 AM flyback: cmos battery dead etc
08:11 AM flyback: you never need a full video port, keyboard etc
08:18 AM Loetmichel: miss0r: i use LinuxCNC on a 2.8ghz core2 duo.. and it can move the machine in LPT mode, parallel encoding the USB webcam AND send the desktop via VNC to a remote machine... https://www.youtube.com/watch?v=9u_ChO1AKYY&t=7s
08:19 AM flyback: they do make pci and pci-e lpt ports
08:19 AM Loetmichel: so while linuxCNC only uses one (pseudo-realtime) core (as far as i know) there IS reason to have more than one core... and be it just to have the GUI be responive
08:19 AM flyback: the only thing that won't work is ecp dma which I don't think anyone uses anyways
08:19 AM flyback: because ecp dma used isa mode dma which is GAY
08:19 AM jthornton: miss0r: its a small pcie plug
08:19 AM Loetmichel: ecp DMA was fine with the LPT port ZIPs... no idea for what one use it today...
08:19 AM Loetmichel: though
08:20 AM miss0r: It would seem I can get just about anything as long as I can disable the power saving options..
08:20 AM miss0r: Excellent.
08:22 AM Loetmichel: miss0r: i just ordered two of these for two new CNC 6040 here at the company: https://www.itsco.de/pc-dell-optiplex-760-sff-intel-core-2-duo-e8500-2x-3-16ghz.html
08:22 AM Loetmichel: so far they work well
08:22 AM Loetmichel: only installed linuxCNC on them and did a short test though because the machine housings are not built yet
08:22 AM miss0r: Indeed. I am looking at the ASROCK J4105M at the moment. reading its manual, it seems I have the needed setting options in the bios
08:35 AM JT-Shop: miss0r: pcw_home would know what current motherboards are good
08:36 AM miss0r: JT-Shop: I've already ordered one :) It was mentioned in a few threads as being quite good, and the manual states that it can disable all sorts of ridiculous powersaving stuff. So, I gave it a shot.
08:37 AM miss0r: I ordered: 1x PSU 1x 4GB ram 1x motherboard w. cpu 1x 120gb SSD.
08:37 AM miss0r: All of which can be reused(other than the motherboard) if the motherboard should fail me
08:41 AM miss0r: I'll take the measurements and send them in, so they can be added to the list
08:43 AM miss0r: Better go pick up the kid. See you around
10:08 AM HexaCube: what do you guys do with your Z-axis when using ballscrews to prevent it from sacking when the machine is off?
10:08 AM Deejay: re
10:08 AM HexaCube: or do you just live with that?
10:09 AM jdh: add a brake?
10:11 AM HexaCube: hmmm
10:11 AM jdh: my steppers hold the Z unpowered
10:12 AM HexaCube: even with ballscrews? I might try and see if it holds, then
10:24 AM cradek: my big machine has a counterweight on chains and pulleys and it balances
10:25 AM cradek: I think it's bad if the servo has to hold up the weight
10:26 AM HexaCube: mhhhm well my axis isn't really gonna be that heavy
10:26 AM HexaCube: maybe 3kg tops? :D
10:26 AM cradek: heh the counterweight on mine is a chunk of lead the size of a suitcase
10:27 AM HexaCube: O_O
10:27 AM HexaCube: wow
10:42 AM flyback: sorry I had to go to my autism meettin and forgot I was chatting with you miss0r
11:13 AM HexaCube: sooo, how uniform is aluminum sheet stock in general?
11:13 AM HexaCube: or well, sheet stock, be it steel or alu
11:24 AM fragalot: hi
11:25 AM robotustra: Could somebody tell me what is the sequence of linuxcnc boot? Or where is it described?
11:25 AM robotustra: who run different modules and who starts gui?
11:26 AM HexaCube: hey fragalot o/
11:28 AM robotustra: is it all described in docs/src/user/starting-linuxcnc.txt?
11:37 AM robotustra: ? If I need to add my gui to lcnc I need to modify src/emc/usr_intf/Submakefile and add compiling options there?
11:44 AM miss0r: fragalot: hello
11:44 AM robotustra: it seems I got it right
11:45 AM miss0r: fragalot: It seems your package has finally reached Denmark. The one I sent you is still mulling around in the same warehouse(acording to the latest timestamp)
11:51 AM JT-Shop: robotustra: you would have to read the code
11:52 AM robotustra: JT-Shop, of emc.cc?
11:52 AM robotustra: JT-Shop, do you want to tell me that linuxcnc is poorly documented for developers?
11:53 AM JT-Shop: lol
11:53 AM JT-Shop: developers just read the code
11:53 AM JT-Shop: might be some info in the documents in the user interface section
11:54 AM JT-Shop: read the python interface
11:54 AM * JT-Shop just noticed that the developer section is not in the pdf
11:55 AM robotustra: I already got how to add UI, and may be got the linixcnc booting sequrnce too..
11:55 AM gloops: these look ok https://www.ebay.co.uk/itm/2x-Haydon-Kerk-RGS08-Linear-Rails-With-Input-Shaft/253823597790?
11:56 AM robotustra: JT-Shop, I don't want any python interface, I'm writing own qt/c++ interface
11:58 AM robotustra: which will be connected not via pyVCP or glade
11:58 AM JT-Shop: go to #hazzy and ask they are doing the same thing
11:59 AM Rab: gloops, teflon-coated aluminum with plastic nut. Not super heavy duty.
11:59 AM robotustra: not sure if the same
11:59 AM robotustra: do their gui will connect through network to HAL?
11:59 AM gloops: Rab..no, i kinda guessed that with the philips head screws
12:00 PM Rab: The guides might be plastic as well, can't tell from the specs.
12:00 PM JT-Shop: robotustra: you need to ask them not me
12:02 PM gloops: Rab they are pretty expensive though lol https://prototypes.haydonkerk.com/ecatalog/rgs-linear-rails/en
12:02 PM gloops: more expensive than rollon
12:02 PM robotustra: JT-Shop, they are doing yet_another_python_thing
12:03 PM robotustra: and I would like to have a c/c++ thing
12:04 PM Rab: gloops, expensive compared to chinesium, but a bargain compared to name brand linear bearing slides. Very low design loads though. I'd guess maybe they're meant for optical benches or similar duty.
12:05 PM gloops: $500 for a single foot long rail?
12:06 PM gloops: i paid £200 for 3 sets of rails and ballscrews 4 ft lol
01:19 PM Tom_L: ok what would you start at for a feedrate on a .03125 endmill at 4k rpm for full width cutting in aluminum?
01:19 PM Tom_L: carbide
01:20 PM cradek: I bet that just won't work without some more spindle speed
01:21 PM Tom_L: probably around 4 ipm maybe
01:23 PM Tom_L: i used em to cut all my plastic hammond enclosures but nothing aluminum yet
01:24 PM Tom_L: the .0625 cutter works good at 4k 6ipm
01:32 PM Tom_L: these only have a .093" DOC
01:47 PM infornography: recommend me a PCIe parallel port card to use with the linuxcnc
01:47 PM infornography: I read "but very few cards are compatible with EPP, which is used with parallel port connected FPGA signal generators and controllers.
01:47 PM infornography: "
01:47 PM Tom_L: pcie and parallel port?
01:47 PM Tom_L: oh nevermind
01:48 PM * Tom_L was thinking mesa cards
01:48 PM infornography: that makes it sound like it will be a pain, but I just want to use it for general I/O
01:48 PM infornography: relays and buttons and stuff
01:49 PM Tom_L: what cards are you using?
01:49 PM Tom_L: or are you using a parallel port
01:49 PM infornography: the DB25 on the motherboard ATM
01:49 PM infornography: I was thinking about adding a second one
01:51 PM infornography: Is a mesa pretty easy to setup?
01:51 PM HexaCube: something I'm wondering. Is it possible at all to get a rusty piece of equipment back to usable condition while still maintaining flat surfaces?
01:51 PM HexaCube: flat/square/precise
01:51 PM Tom_L: easy as anything
01:52 PM Tom_L: since you have a parallel port i'd look at the 7i90
01:52 PM Tom_L: and a daughter card for it or a bob or something
01:54 PM CaptHindsight: infornography: http://wiki.linuxcnc.org/cgi-bin/wiki.pl?WCH
01:55 PM CaptHindsight: infornography: if the PP card is for non-realtime then any will work, even USB --> PP
01:56 PM infornography: oh sweet, I have options then, thanks
02:02 PM fragalot: miss0r: they must be having a secret meeting
02:09 PM JT-Shop: infornography: yes Mesa cards are pretty straight forward to setup, which one are you thinking about?
02:11 PM CaptHindsight: https://www.chemistryworld.com/news/reverse-liquid-sieve-lets-only-large-particles-pass/3009410.article fun stuff
02:14 PM fragalot: weird
02:14 PM infornography: JT-Shop: I have no idea, just started looking at them.
02:14 PM JT-Shop: is it a stepper machine?
02:15 PM infornography: yes
02:16 PM JT-Shop: this is a new lower cost stepper solution https://mesaus.com/index.php?route=product/product&path=66&product_id=150
02:16 PM JT-Shop: if you don't need all the I/O a 7i76e has the 7i96 is a lot more cost effective
02:17 PM * JT-Shop sees that break second is over with and heads back to making sparks
02:18 PM infornography: Doing this stuff over ethernet seems amazing to me.
02:19 PM fragalot: ethernet is very high bandwidth, and if it's dedicated it's also easy to do realtime packets over
02:22 PM infornography: https://cdn.discordapp.com/attachments/442435176585232386/486616701925064706/iu.png
02:26 PM infornography: I need a sugar-mama to help pay for all these cool toys
02:27 PM fragalot: lol
02:29 PM gloops: dont do it
02:33 PM XXCoder: very green
02:43 PM gloops: well, nobody building who needs expert technical advice tonight
02:45 PM infornography: I could use some expert technical advice in a to-go bag for later.
03:10 PM * fragalot loves machines like this: https://imgur.com/gallery/0OYeFM5
03:12 PM HexaCube: https://i.imgur.com/wfaNe73.jpg
03:12 PM HexaCube: :P
03:12 PM HexaCube: fragalot: how about this ^
03:13 PM XXCoder: tiny machine
03:13 PM HexaCube: and I keep thinking our CNC machines are heavy with like... 50 tons top
03:13 PM XXCoder: jk heh
03:13 PM fragalot: that's a big boy, :D
03:13 PM HexaCube: the gantry alone of that thing ways over 100 tons
03:13 PM XXCoder: HexaCube: for any machine type theres ricious version of it
03:13 PM HexaCube: oh, just the horizontal beam is 100t+
03:13 PM HexaCube: not the whole gantry
03:14 PM XXCoder: theres presses that can press to one million tons
03:14 PM XXCoder: not pounds, tons
03:14 PM HexaCube: yeah, nuts
03:14 PM HexaCube: and after working at the company for a year I still didn't see how they get the big machines on a truck
03:14 PM HexaCube: :(
03:15 PM fragalot: in pieces
03:15 PM HexaCube: nope
03:15 PM XXCoder: yeah theres always eyehook attachments somewhere in parts
03:15 PM HexaCube: no no
03:15 PM HexaCube: the thing is
03:15 PM HexaCube: the largest crane I saw so far was for 35 tons
03:15 PM fragalot: There is zero chance that the machine you just showed fits onto a single truck
03:15 PM HexaCube: fragalot: no no
03:15 PM HexaCube: the machines *we* make
03:15 PM fragalot: Ah
03:16 PM HexaCube: they weigh up to 50 tons but they're put as a whole on a truck, but I *never* saw a crane large enough to lift it
03:16 PM HexaCube: actually
03:16 PM fragalot: 2 cranes, or rent a larger one?
03:16 PM XXCoder: maybe they have special lift system to put it in place
03:16 PM HexaCube: i just realised how they do it
03:16 PM fragalot: what machines do you guys make anyway
03:17 PM HexaCube: 5 axis cnc centers
03:17 PM fragalot: brand?
03:17 PM HexaCube: Grob
03:18 PM HexaCube: https://www.grobgroup.com/en/products/product-range/universal-machining-centers/milling-centers/g350/
03:18 PM HexaCube: from that up to this: https://www.grobgroup.com/en/products/product-range/universal-machining-centers/milling-centers/g1050/
03:19 PM fragalot: we're currently looking at machines with at least 1800x800mm working area
03:19 PM fragalot: Z height 1200
03:20 PM HexaCube: mhmm, the G1050 would be 1600x1700x1540
03:20 PM HexaCube: not quite large enough
03:20 PM fragalot: also no real need for 5 axis for what we do
03:20 PM HexaCube: well that one comes as a 4 axis aswell
03:20 PM fragalot: current one we're looking at is the rittal perforex series
03:21 PM fragalot: but i'm a bit afraid that that thing is going to be a one trick pony (because it is)
03:21 PM HexaCube: (but to be fair, I just know a few random bits about our machines so far, I'm in an apprenticeship)
03:22 PM HexaCube: also i dunno how expensive or cheap our machines are in comparison with other manufacturers
03:22 PM fragalot: given the focus appears to be precision multi-axis.. doubt it's cheap :-)
03:23 PM HexaCube: i think the smallest (the G350) starts at around 350 grand
03:23 PM fragalot: yea, we're trying to stay under 300
03:23 PM HexaCube: But we're leader in the automobile sector, that much I do know
03:30 PM fragalot: heh just saw something i've never thought of before that makes so much sense
03:30 PM fragalot: simple bolt with a hole drilled through the middle to use as a drill guide to drill out broken recessed bolts
03:37 PM XXCoder: not bad
03:41 PM SpeedEvil: :)
03:57 PM Deejay: gn8
07:04 PM robotustra: has a question
07:05 PM robotustra: when I try to home axii in emulator, I can home X,Y but when I home Z axis I get "Cannot home while shared home switsh is closed"
07:05 PM robotustra: what I should modify in ini file to fix this error?
07:12 PM Wolf__: might be set up as shared home switch, might need to back one of the axis off after homing
07:14 PM robotustra: no
07:14 PM robotustra: I just got the answer!
07:14 PM Wolf__: what was it?
07:14 PM robotustra: Z axis should be homed FIRST
07:14 PM Wolf__: makes sense lol
07:15 PM robotustra: I mean I'm not sure that it's right answer but id does work :)
07:15 PM robotustra: I don't know if it's a bug or fiture
07:16 PM robotustra: and one more thing: the manual example for linuxcncrsh is incorrect
07:17 PM robotustra: it should be fixed
07:17 PM robotustra: who is fixing it?
07:17 PM Wolf__: real life usually home Z first so you dont crash it in to the vise when homing x/y
07:20 PM robotustra: the example about linuxcncrsh tells that "set machine on" works before "set estop off" but it's incorrect
07:20 PM robotustra: it doesn't work
07:20 PM robotustra: here http://linuxcnc.org/docs/html/man/man1/linuxcncrsh.1.html
07:21 PM robotustra: and "set mode manual" is not working before "set estop off"
07:21 PM robotustra: example is not good
08:48 PM _unreal_: sup
08:50 PM pink_vampire: hi _unreal_
08:50 PM _unreal_: so annoying, I had a scab on my neck. I TOUCHED it, it fell off and now its a gusher WTF
08:53 PM robotustra: did you read instruction before use it?
08:58 PM pink_vampire: robotustra: LOL what??
08:59 PM robotustra: hm... sorry, I read "scrub" instead of scab
09:17 PM _unreal_: hi pink_vampire
09:18 PM _unreal_: I should take a photo of the control box I'm building for the cnc machine
09:18 PM pink_vampire: sounds like a good idea to me
09:21 PM infornography: I like photos
09:21 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/rue/encoder/encoder5.jpg
09:21 PM _unreal_: uploading photos
09:21 PM _unreal_: interesting encoder wheels
09:22 PM _unreal_: https://drive.google.com/open?id=1qtyn36xbzOtYdjsWVXdHtWyrit9U4Nb2
09:22 PM _unreal_: https://drive.google.com/open?id=1VuWi4w-v-lE5sGZ6tAHAAxRP-2heC2kG https://drive.google.com/open?id=1d1PfMk_1-QrUtzIXGeXMF_sW-gVF-Dy6
09:22 PM pink_vampire: Tom_L: just get an encoder they about 20$
09:23 PM Tom_L: i don't need any
09:23 PM _unreal_: https://drive.google.com/open?id=1PcbojNl4Kx1_xkY0tDm9yc4JzDaOVeSX
09:23 PM Tom_L: parts for someone
09:23 PM _unreal_: Tom_L, fight the power
09:23 PM _unreal_: err sell the power
09:23 PM _unreal_: lol
09:23 PM pink_vampire: _unreal_: interesting looking box
09:24 PM _unreal_: the box was an power system for a camera flash
09:24 PM infornography: The foot in the photo adds class
09:25 PM _unreal_: originally it had hardware for driving a high power flash for a camera
09:25 PM _unreal_: yes a nice tan sandle foot
09:27 PM _unreal_: approx the box is like 10"x14"x20"
09:28 PM robotustra: it looks like I can connect to linuxcncrsh using qtsocket
09:28 PM robotustra: it means that I can quite easy attach my gui to linuxcnc
09:28 PM _unreal_: linunxxnxrsh?
09:29 PM _unreal_: I dont know what that means
09:29 PM Tom_L: then you don't need one
09:31 PM robotustra: it's a console client to linuxcnc
09:31 PM infornography: rsh? Can you linuxcnc via terminal?
09:31 PM robotustra: yes
09:31 PM infornography: O:
09:32 PM robotustra: you can run linuxcncrsh instead of any gui or in parallel
09:32 PM robotustra: and send commands directly from console to linuxcnc
09:33 PM robotustra: and see what's going on in GUI
09:36 PM robotustra: infornography, linuxcncrsh is in the packet
09:40 PM infornography: very cool
09:58 PM infornography: what sort of dial indicator stands are the cool kids using?
09:58 PM pink_vampire: infornography: hat do you mean?
09:58 PM Wolf__: mag base? noga
10:01 PM infornography: The stuff I'm playing with at home is mostly aluminum so a mag base doesn't stick, It has me looking at bases.
10:01 PM pink_vampire: O_o
10:01 PM Wolf__: then pick a surface gauge
10:02 PM Wolf__: or a height gage + indicator holder
10:03 PM pink_vampire: infornography: what are you trying to measure?
10:03 PM Wolf__: how would be better question
10:05 PM infornography: I was measuring backlash the other day. I bolted a 123 block to the table to get the base to stick.
10:06 PM pink_vampire: i can't see a problem with what you did.
10:06 PM Wolf__: normal practice
10:07 PM infornography: noga looks fancy
10:07 PM Wolf__: I used a 123 block + my noga and a .0001” DTI to check my surface plate for holes
10:07 PM pink_vampire: noga is just a mag base
10:08 PM Wolf__: very quality mag base
10:08 PM infornography: There was no problem, just curious what people are using
10:09 PM Wolf__: I use lots of things, kinda depends on what I’m trying to measure lol
10:09 PM pink_vampire: I have one cheap grizzly that work very nice
10:12 PM Wolf__: I have a china mag base but I love the noga https://i.imgur.com/0CawFmP.jpg
10:15 PM infornography: I've never used a base with arms like that, it looks fancy
10:15 PM infornography: *add to cart
10:15 PM Wolf__: lol
10:15 PM pink_vampire: so how did you use it??
10:16 PM Wolf__: ?
10:18 PM infornography: are you putting a DRO on that?
10:18 PM infornography: in that image
10:18 PM Wolf__: https://i.imgur.com/pj1M5zS.jpg did =)
10:18 PM infornography: This is what I am used to https://media.midwayusa.com/productimages/880x660/Primary/779/779899.jpg
10:19 PM Wolf__: yeah, I have one of those as well
10:19 PM Wolf__: and a starrett single knuckle
10:20 PM pink_vampire: infornography: it is not bad arm for indicate on a lathe but go with noga / noga style arm
10:21 PM Wolf__: not a bad thing to have more then one base anyways
10:21 PM Wolf__: I have had times that I have needed 2
10:22 PM infornography: now if it would stick to aluminum
10:23 PM Wolf__: I still want to add a clamping bar so I can quickly mount a noga arm on my mill head, all rounded so mag bases dont stick well
10:23 PM pink_vampire: infornography: the flex joint can give you problems sometimes
10:24 PM pink_vampire: Wolf__: 3 ball magnets base??
10:24 PM infornography: Maybe a big steel washer, and a few strategically placed tapped holes
10:25 PM Wolf__: https://i.imgur.com/pj1M5zS.jpg look at the mill head, see anything flat on there lol
10:26 PM infornography: not sure if that is a desk or chest freezer
10:26 PM Wolf__: was a photo slide cabinet
10:27 PM infornography: I can't keep people from using the chest freezers as tables
10:27 PM Wolf__: flat surface = stuff magnet
10:31 PM pink_vampire: https://store.hexagonmetrology.us/romer-magnetic-base
10:33 PM infornography: qty 7, add to cart
10:33 PM pink_vampire: 7???????
10:33 PM infornography: go get loan
10:34 PM infornography: thats pretty expensive
10:35 PM pink_vampire: it's a base for a cmm arm
10:35 PM pink_vampire: infornography: https://www.youtube.com/watch?v=w6Sk7wroeJs
10:35 PM Wolf__: I’ll probably spend 3x that sometime in the next week
10:36 PM * Wolf__ needs a new shop tool
10:36 PM flyback: woot
10:37 PM flyback: I just upgraded two win7 boxes to 10 free and will do a 3rd soon
10:37 PM flyback: nice for stuff that needs windows
10:37 PM Wolf__: expect for the windows part =P
10:37 PM flyback: well I have lots of old dells that won't have 7 or 10 licences
10:37 PM flyback: those got linux on them :)
10:38 PM infornography: RIP windows 7
