12:00 AM Wolf__: ahh, learn something new every day
12:03 AM flyback: http://www.jamestownbpu.com/electric/anatomy.php
12:03 AM flyback: you can also use excited voltage to regulate output
12:03 AM flyback: that's what car alternators use
12:03 AM Wolf__: yeah
12:06 AM flyback: pumps as turbines aren't the most efficient but they are so cheap and easy to source it doesn't matter that much
12:06 AM Wolf__: I know a guy, loads of industrial odd stuff
12:06 AM flyback: dpm
12:07 AM flyback: don't need a damn either just a pipe inlet
12:11 AM Wolf__: I have a spring fed pond, thats where my interest starts =)
12:11 AM hazzy-lab: flyback: the exciters I'm used to weigh about 40tons, but that's still tiny compared to the generators at 600tons :D
12:11 AM flyback: yep
12:11 AM flyback: hazzy-dev, have you seen them dry ice blast them
12:11 AM fragalot: hi
12:11 AM hazzy-lab: flyback: No
12:11 AM flyback: lemme find some
12:11 AM flyback: https://www.youtube.com/watch?v=x_JkfZsOyMY
12:11 AM hazzy-lab: I have watched them spin test them, which is pretty impressive. I was surprised that they needed to be cooled just for spinning, but the the air friction is significant enough to heat them up a good bit
12:11 AM flyback: well the loads also heat them up
12:11 AM flyback: even my little 1400w gas generator I put a big fan on during an outage
12:12 AM flyback: went from 400f TO 260
12:12 AM flyback: LOW PRESSURES only remove dirt and grease
12:13 AM flyback: high pressure will remove lead paint
12:13 AM flyback: which is nice because you only have lead paint to vacume up and take to disposal plant
12:13 AM hazzy-lab: flyback: there is no current during the spin test, it is just the rotor
12:13 AM flyback: if you used sand them you have leaded sand
12:13 AM flyback: big mess
12:13 AM flyback: that's what destroyed that russian power plant
12:13 AM hazzy-lab: that is neat, also the dry ice just sublimates and does not leave any residue
12:14 AM flyback: weld imbalanced and they ignored it
12:14 AM flyback: correct
12:17 AM flyback: wolf if you only want a few dozen watts or have very small flow, then a perm magnet generator might be better
12:19 AM hazzy-lab: talking about imbalance: one the the siemens generators failed recently on initial start up. tuned out they had used propane torches (instead of induction) to heat the ends of the shaft to plug the inspection bore and the combustion gases had condensed in it and threw it out of balance. it was a pretty major crash, destroyed the bearings mounts and did some damage to the turbine
12:19 AM Wolf__: yeah, tie it in to a battery bank to supplement a solar system
12:20 AM hazzy-lab: flyback: would an auto alternator be worth anything for a small hydro plant, or would it be too inefficient?
12:20 AM flyback: probably not as is nheeds high rpm
12:21 AM hazzy-lab: yeah, true
12:23 AM flyback: then again induction also are rpm sensitive
12:23 AM flyback: hmm
12:24 AM laminae_: >.>
12:24 AM laminae_: Hey guys, have some first time setup issues, after installing preemptive kernal for 7i76e and using a known pncconfig i encounter "unable to retrieve mac address" i have moved the w3 jumper up and edited the .hal file to 10.10.10.10 also set ethernet to static 10.10.10.1
12:24 AM hazzy-lab: flyback: well, induction is RPM sensitive it you want 60Hz output :)
12:25 AM laminae_: I'm power tb1 and tb3 also, only illuminated led is the power led
12:25 AM Wolf__: true, for a small home setup I have been thinking a system tied to a battery bank like the power wall would be nice
12:25 AM laminae_: i'm powering*
12:31 AM Wolf__: no idea here laminae_
12:34 AM laminae_: Ah well, thanks anyway
01:03 AM flyback: NIGHT
01:05 AM Laminae_: hmm
01:06 AM Laminae_: Could anyone verify from network folder if this looks correct for static ip to my 7i76e?:
01:06 AM Laminae_: auto lo eth0
01:07 AM Laminae_: iface lo inet loopback
01:07 AM Laminae_: Whoops, copied from incorrect window
01:08 AM Laminae_: auto lo enp3s0
01:08 AM Laminae_: iface enp3s0 inet static
01:08 AM Laminae_: address 10.10.10.1
01:08 AM Laminae_: netmask 255.255.255.0
01:09 AM Laminae_: If i pint 10.10.10.10 it does get a reply but i'm wondering if there might be some other communication issue?
01:09 AM Wolf__: board firmware?
01:10 AM Laminae_: Is there a way to check without connecting?
01:11 AM Laminae_: I'm willing to bet i'm just doing something really stupid
01:11 AM Laminae_: I've never setup linuxcnc before
01:11 AM Wolf__: there is a set of directions somewhere
01:12 AM Laminae_: I've follow several of them including ones for the specific pc i am using
01:12 AM Laminae_: I tried different isos to be certain as well
01:12 AM Laminae_: currently using the one from this https://forum.linuxcnc.org/38-general-linuxcnc-questions/33969-7i76e-quick-setup
01:14 AM Wolf__: dunno, the few guys that know the mesa stuff inside out are usually on day/evening central time USA
01:14 AM hazzy-lab: Laminae_: I don't know anything about the ethernet cards, but looking at a config I have for one it looks like the IP is 10.10.10.10
01:15 AM hazzy-lab: http://dpaste.com/1DHPD0X
01:15 AM Laminae_: Yeah, my .hal file does match that
01:16 AM hazzy-lab: ok, that is all the help I can be, sorry :)
01:16 AM Laminae_: Thanks!
01:16 AM Laminae_: Just a sanity check is nice at this point haha
01:16 AM hazzy-lab: haha, yes
01:16 AM Wolf__: some day I need to get a ether thingy to try out
01:17 AM * hazzy-lab thinks the same
01:17 AM Laminae_: I'm really regretting it at this point >.>
01:17 AM Laminae_: Been mesing with this for many hours
01:19 AM Laminae_: I'm guessing this isn't really helpful but just in case on of you guys can glean more from it, this is the dump http://dpaste.com/1R3MKJM
01:20 AM Laminae_: Line 29 being the cause
01:21 AM Laminae_: If i run: Ip addr show
01:21 AM Laminae_: From terminal
01:21 AM Laminae_: I get this: http://dpaste.com/135NDGQ
01:26 AM rmu|w: Laminae_: you have assigned 10.10.10.10 to your ethernet interface
01:27 AM rmu|w: Laminae_: so if you ping 10.10.10.10 what will happen is you effectivly ping the loopback
01:27 AM Laminae_: Ah, i figured i did something stupid
01:28 AM Laminae_: If i use eth0 i get an error, and i thought i google foo'ed my way through, clearly not
01:28 AM rmu|w: it is called enp3s0
01:30 AM Laminae_: In that case, what should i be using as the name for my ethernet?
01:30 AM rmu|w: you could try "ifconfig enp3s0 10.10.10.1/24" and then ping 10.10.10.10
01:31 AM rmu|w: the "ip neigh | grep 10.10.10.10" should show the mac addr of the mesa card
01:31 AM Laminae_: Awesome, gonna give that a whirl
01:31 AM Laminae_: My distro doesn't support that command but i think i know how to do it (maybe)
01:32 AM rmu|w: ok then you could delete the wron address with something like "ip a d 10.10.10.10/24 dev enp3s0"
01:33 AM rmu|w: but it all depends where you configured that address in the first place, if it was networkmanager it could be it will put it back in a minute or so
01:34 AM Laminae_: I edited in "/etc/init.d/networking"
01:34 AM Laminae_: One sec, i'll link my broken attempt
01:35 AM Laminae_: http://dpaste.com/1K968KA
01:37 AM rmu|w: Laminae_: that looks ok, do you know where the 10.10.10.10 in the output of ip addr show did come from?
01:38 AM Laminae_: It only showed after i saved that file
01:38 AM Laminae_: Prior to that it was all 0
01:39 AM Laminae_: To confirm loop, i unplugged the 7i76e and pinged the ip and it is indeed stuck in a loop
01:39 AM Laminae_: Which makes me think that file is the cause
01:39 AM rmu|w: if you edited network init, you have to restart it somehow
01:39 AM rmu|w: what distro is that anyway?
01:41 AM Laminae_: A stretch that i pulled from: https://forum.linuxcnc.org/38-general-linuxcnc-questions/33969-7i76e-quick-setup
01:41 AM rmu|w: then AFAIK the file you want to edit is /etc/network/interfaces
01:41 AM Laminae_: Restarted after each change
01:41 AM rmu|w: how did you restart?
01:42 AM Laminae_: sudo /etc/init.d/networking restart
01:43 AM rmu|w: Laminae_: can you show current contents of /etc/network/interfaces ?
01:43 AM Laminae_: That was what i last linked
01:43 AM Laminae_: In dpaste
01:43 AM sealive: morning from Germany
01:43 AM rmu|w: ok
01:44 AM Laminae_: I'm feeling pretty confident that is where i went awry
01:44 AM rmu|w: Laminae_: sudo ifdown enp3s0
01:44 AM rmu|w: Laminae_: sudo ifup enp3s0
01:44 AM rmu|w: Laminae_: then, in the output of "ip a s", the line showing 10.10.10.10 should be gone
01:45 AM Laminae_: "ifdown: interface enp3s0 not configured"
01:45 AM Laminae_: sudo ifup enp3s0 RTNETLINK answers: File exists ifup: failed to bring up enp3s0
01:45 AM sealive: the pc needs to be 10.10.10.1
01:45 AM sealive: the mesa got the 10
01:46 AM sealive: you will do a loopback on getting both to the same
01:46 AM rmu|w: Laminae_: can you do "ip a d 10.10.10.10/24 dev enp3s0" ?
01:46 AM Laminae_: "RTNETLINK answers: Operation not permitted"
01:46 AM rmu|w: Laminae_: with sudo of course
01:46 AM rmu|w: sorry
01:47 AM sealive: sudo ifconfig enp3s0 10.10.10.2
01:47 AM MrHindsight is now known as CaptHindsight
01:47 AM Laminae_: Might be working
01:47 AM Laminae_: One sec
01:47 AM rmu|w: sealive: no ifconfig there
01:47 AM sealive: rmu|w, what os iss he using
01:47 AM rmu|w: sealive: stretch
01:47 AM Laminae_: http://dpaste.com/1EKJ6QP
01:48 AM Laminae_: Still no connection to mesa
01:48 AM rmu|w: Laminae_: now sudo ifdown/up enp3s0
01:48 AM rmu|w: like before
01:48 AM Laminae_: Got it
01:50 AM Laminae_: Current ip addr show: http://dpaste.com/0VVQ9DT
01:51 AM rmu|w: ifup did not complain?
01:51 AM rmu|w: strange
01:51 AM sealive: rmu|w, why dident he install the net-tools
01:51 AM sealive: then you got all the benefits
01:52 AM Laminae_: Ignorance
01:52 AM sealive: ok
01:52 AM sealive: then im out
01:52 AM Laminae_: I'm swinging in the dark
01:52 AM rmu|w: sealive: it should not matter
01:52 AM sealive: watering the garden
01:52 AM rmu|w: Laminae_: ip a a 10.10.10.1/24 dev enp3s0
01:52 AM rmu|w: Laminae_: sudo ip a a 10.10.10.1/24 dev enp3s0
01:53 AM rmu|w: Laminae_: something with ifup-ing did not work because the interface is DOWN
01:53 AM Deejay: moin
01:54 AM Laminae_: Progress? http://dpaste.com/377RVGT
01:54 AM Laminae_: Herro
01:54 AM Laminae_: I'll rerun ifdown/u[
01:55 AM rmu|w: waitz
01:55 AM Laminae_: $ sudo ifup enp3s0 RTNETLINK answers: File exists ifup: failed to bring up enp3s0
01:55 AM rmu|w: ok
01:55 AM Laminae_: WOnder if i can just set up obs real quick >.>
01:55 AM rmu|w: if it still shows DOWN you can UP it with sudo ip link set enp3f0 up
01:56 AM rmu|w: plugin you network cable
01:56 AM Laminae_: Done
01:57 AM Laminae_: Success!
01:57 AM rmu|w: and can you ping your mesa card
01:57 AM Laminae_: I could kiss you right now
01:57 AM rmu|w: yw, but i'm fine without ;)
01:58 AM Laminae_: Man, i know i had screwed that up, no idea how to fix it x.x
01:58 AM Laminae_: I really appreciate your help
01:58 AM rmu|w: of course you have to check if /etc/network/interfaces is correct and the config survives a reboot
01:58 AM Laminae_: Either way, now i at least know where the problem is
01:59 AM Laminae_: But yeah
01:59 AM rmu|w: with the ip command, you can abbreviate all commands
01:59 AM rmu|w: so "ip a s" is short for "ip addr show"
01:59 AM rmu|w: adding "help" usually gives a terse synopsis
02:00 AM rmu|w: i have to go, back in about an hour
02:00 AM Laminae_: Ah, perfect, i'm very light on linux experience, just debian stuff from pi projects
02:04 AM Laminae_: Brb, testing reboot
02:18 AM Laminae_: And works after reboot, score!
02:52 AM rmu|w: nice
03:10 AM Laminae_: So, i'm plugging in a driver and motor to test and i'm using a gecko g251x which i believe is considered an active high driver, so i only connect step and dir (two wires) to controller, should those be connected to high respectively, since it is an active high driver that seems to make sense to me but ya know...
03:11 AM Wolf__: need to hook up the - for the step/dir
03:12 AM Wolf__: motor driver won’t work without both sides of the signal
03:13 AM Laminae_: I think i explained poorly, this is my driver: https://www.geckodrive.com/g251x.html#amfile_files
03:16 AM Wolf__: ok should be in the config to set it to source signals vs sinking
03:17 AM Wolf__: or something
03:18 AM Laminae_: I'll dig through real quick
03:18 AM Laminae_: But it would be connect to the positive side of the signal on controller?
03:18 AM Wolf__: yeah
03:19 AM Laminae_: Cool beans, sorry for so many dumb questions
03:20 AM Wolf__: wiring should be the easy part =)
03:23 AM rmu|w: Laminae_: don't forget ground connections
03:24 AM Laminae_: Looks like there is a drop down menu for every gecko driver BUT that one and the g250x rip
03:31 AM rmu|w: Laminae_: drop down where?
03:32 AM Laminae_: In axis tabs
03:32 AM Laminae_: Doesn't say it would switch it to sourcing, i'm search the googles now
03:32 AM Laminae_: I can't be the first person to use these drivers
03:33 AM rmu|w: don't understand what you are talking about
03:33 AM rmu|w: connect terminal 9-terminal 12 of your gecko to the mesa card
03:33 AM rmu|w: 12 to ground
03:34 AM Wolf__: those settings arent in axis (I think), if its needed to be set it will be in the mesa directions
03:34 AM rmu|w: Wolf__: i think Laminae_ is talking about Axis tab in pncconf or some other configuration program
03:34 AM Wolf__: its also 4:30am for me, so I could be wrong
03:34 AM rmu|w: Wolf__: not Axis the LinuxCNC GUI
03:35 AM Wolf__: yeah, I know where he is talking about, I know I read somewhere about mesa signal settings
03:36 AM rmu|w: Laminae_: IIRC the driver selection in stepconf and pncconf selects the timing of step/dir signals
03:37 AM rmu|w: Laminae_: some other gecko driver should be fine, that can always be changed later
03:38 AM Laminae_: Correct, pncconfig
03:38 AM Laminae_: Still looking for signal sourcing
03:40 AM Laminae_: I also have CR1 led on which is apparently an fpga issue
03:43 AM rmu|w: Laminae_: what do you mean with signal sourcing
03:44 AM Laminae_: My drivers only have a step and dir input from controller
03:44 AM Laminae_: They are active high drivers
03:45 AM rmu|w: ???
03:45 AM rmu|w: Laminae_: do you have gecko 251 drivers?
03:45 AM Wolf__: double check the mesa manual
03:45 AM Laminae_: Those are the exact drivers i have
03:46 AM Laminae_: g251x
03:46 AM rmu|w: Laminae_: the user manual explains how to wire them up
03:47 AM rmu|w: Laminae_: the word "active" isn't even mentioned there
03:47 AM rmu|w: Laminae_: connect terminals 9 to 12
03:47 AM Laminae_: Yeah, i googled driver types to try and figure it out
03:48 AM Laminae_: The manual says "connect pin 10 to step"
03:48 AM Laminae_: https://www.geckodrive.com/amfile/file/download/file_id/29/product_id/18/
03:48 AM Laminae_: connect pin 9 to direction
03:48 AM Laminae_: pretty unhelpful
03:48 AM rmu|w: connect 11 to enable
03:48 AM rmu|w: connect 12 to ground
03:48 AM rmu|w: Laminae_: what information would be considered helpful? what do you need?
03:49 AM Laminae_: Am i missing something? pin 11 reads disable
03:50 AM Wolf__: hmm
03:50 AM Wolf__: The 7I76E provides five channels of step/dir interface with buffered 5V differential signal pairs. Each differential pair consists of two complementary 5V outputs. The differential signals allows reliable signal transmission in noisy environments and can directly interface with RS-422 line receivers. Step motor drives with single ended inputs connect to just one of the STEP and DIR signal outputs, that is either the STEP+/DIR+ or
03:50 AM Wolf__: STEP-/DIR- signals, with the unused signals left unconnected at the 7I76E. The input common signal on drives with single ended inputs connects to the 7I76Es GND or 5VP pins depending on the drive type.
03:51 AM Laminae_: ooh, perfect, which page was that on?
03:51 AM Laminae_: And thanks, exactly what i was looking for
03:51 AM Wolf__: I was thinking about something on the field outputs
03:51 AM rmu|w: page 11
03:52 AM Wolf__: page 15 of the 7i76E manual
03:52 AM Wolf__: http://www.mesanet.com/pdf/parallel/7i76eman.pdf
03:53 AM rmu|w: mesa documentation does not contain any redundant information ;)
03:53 AM rmu|w: i was looking at http://www.mesanet.com/pdf/parallel/7i76man.pdf
03:53 AM Laminae_: Awesome, now i just need to figure out my fpga issue and i might be able to actually move an axis haha
04:02 AM Laminae_: Can i use g0 zero with feed rates like i would on my printers?
04:07 AM Wolf__: sorta
04:16 AM Laminae_: We have success!
04:16 AM Laminae_: I still have no idea why cr1 is on, however i am moving axis and limit switch works
04:16 AM Laminae_: Gonna wire up the estop before i do the other tests
04:16 AM Laminae_: But man, you guys have been awesome!
04:17 AM rmu|w: it may look like black magic, but there is none involved ;)
04:20 AM Laminae_: Ya know i went into this thinking "man, i've built a cnc laser and 3d printers, how bad can it be?
04:20 AM Laminae_: I wish i had bought a better frame to start with now too
04:24 AM XXCoder: fragged
04:51 AM jthornton: morning
04:51 AM XXCoder: hey hows things
04:52 AM jthornton: dunno just woke up
04:59 AM XXCoder: lol ok
05:34 AM Laminae_: for estop on 7i76e do I need to set up a pullup resistor or if i configure it to estop in I/O to estop do i just put a switch between that pin and ground?
05:41 AM jthornton: Laminae_: http://gnipsel.com/linuxcnc/configs/7i77.html
05:41 AM Tom_L: nice thunderstorm to wake up to today
05:42 AM jthornton: we are due some tonight
05:42 AM Tom_L: rolled in around 4:15
05:42 AM Tom_L: hoping it'll let up so the dogs can make their morning run
05:43 AM Laminae_: jthornton: thanks
05:43 AM jthornton: yw
05:44 AM Tom_L: how do the chicks act in a thunderstorm?
05:44 AM jthornton: they usually just run under the coop when it rains heavy
06:08 AM jthornton: my neighbor finally figured out what was taking the guinea eggs a big old black snake
06:22 AM skunkworks: huh - I haven't updated this system in a while..
07:39 AM JT-Shop: hazzy-dev: hazzy-lab hazzy-m https://github.com/jethornton/7i96/issues/5
07:45 AM robotustra: def str2bool(v):
07:45 AM robotustra: return v.lower() in ("yes", "true", "t", "1")
07:46 AM robotustra: but it might be not helpful
08:03 AM LilyFaith: Anyone here? I am a network admin. I know almost nothing about manufacturing, but I work for a manufacturing company. We have a bunch of old excellon CNC 6's attached to Mark V drills. I was originally brought over to figure out if there is a way to upgrade the 5.25 inch drives to USB drives. But my question is why do we need these Excellon CNC 6 controllers from the 70s at all? This software seems like it should do what we
08:04 AM LilyFaith: The PC? I know that isn't a simply question but if someone could point me in the right direction to get started I would appreciate it
08:06 AM skunkworks: I think your first message got cut off.
08:07 AM skunkworks: but yes - linuxcnc is used for exactly that. Converting old machines to current software
08:07 AM robotustra: of cause there are some sense in moving to new hardware-software to control cnc
08:07 AM robotustra: becase chips are degrade with the time
08:08 AM LilyFaith: But how do I figure out where to start with connecting it. In other words (Again I expect this is not a simple question but...) where do I plug the Mark 5 into the PC?
08:09 AM robotustra: first you have to find where PC part connects to the stepper controllers
08:10 AM skunkworks: heh. you don't. You replace the mark 5.. you have to go though the electronics and see what bits you can keep. (maybe servo drives and such)
08:10 AM robotustra: after you have to find out how motors/servos are controlled
08:11 AM robotustra: and after that replace PC part with new hardware/software complex
08:11 AM LilyFaith: One of you guys want to come to florida and do that?
08:11 AM robotustra: ha ha ha
08:12 AM robotustra: it looks like real job offer?
08:12 AM LilyFaith: I have no idea where to even start. Like I said, I am a IT guy. I don't understand any of this stuff you guys are talking about
08:12 AM JT-Shop: Pete lives in florida
08:12 AM LilyFaith: It could be a real job offer.
08:13 AM LilyFaith: If you could be sure it can be done
08:13 AM LilyFaith: and wont affect the reliability of these machines in a negative way
08:13 AM skunkworks: I am an IT guy.. Don't all IT guys know electronics?
08:13 AM robotustra: unless they are IT girls
08:14 AM skunkworks: then they know more...
08:14 AM LilyFaith: I know some ;) But I am a software dev/project manager/network admin. Hardware (Even PC Stuff) isn't my thing
08:17 AM robotustra: that's sad, such a big country, luck of pros
08:18 AM LilyFaith: Who is Pete?
08:23 AM robotustra: LilyFaith, do you have a spec of the system?
08:26 AM LilyFaith: I can stand in front of it and tell you anything you can describe where to look. But other than that no. I know I have a Mark V drill and its attached to a CNC-6
08:31 AM robotustra: it's not enough of information to find out what the system is
08:32 AM LilyFaith: I understand that. I just don't know how to figure out the answers to your questions. Do you want me to take pictures of something?
08:42 AM jdh: where in FL
08:43 AM LilyFaith: Saint Pete
08:45 AM JT-Shop: a couple of photos along with what it does would help
08:47 AM gregcnc: PCB router
08:48 AM gregcnc: or just a drill specifically
08:48 AM gregcnc: does it take G code now?
08:50 AM LilyFaith: Yes
08:53 AM LilyFaith: It takes G Code now
08:54 AM LilyFaith: Im being told it is a drill not a router
08:54 AM gregcnc: I was just thinking in terms of getting code to it, vs how it's done now
08:55 AM gregcnc: somebody needs to look inside the control panels and see what sort of drives it has
08:55 AM gregcnc: that will determine how much work is needed to make the upgrade to Linuxcnc, though I think most drives can be used.
08:58 AM LilyFaith: https://imgur.com/a/Zvpugj2
09:00 AM gregcnc: only two axis drives? what controls the drill heads? pneumatics?
09:01 AM JT-Shop: looks like servo drives to me, take a photo of the motors that move the axis
09:03 AM gregcnc: as old as it is i would expect analog drives and not too much complication
09:04 AM gregcnc: there probably isn't any Gcode for Z moves, just a drill command
09:11 AM cradek: it's clearly velocity mode servos, not sure what the J6 A-F devices are, or the DO NOT REMOVE board
09:12 AM cradek: the J6 sure get hot
09:12 AM cradek: looks like single phase power, surprisingly
09:13 AM cradek: how old are these? I don't see anything like a computer/cpu in your photos
09:46 AM skunkworks: he said at the begining - 70's but I bet a little newer
09:46 AM LilyFaith: Im heading back to take more pictures
09:46 AM cradek: might be a computer in the control head then, which we didn't get pictures of
09:46 AM gregcnc: PC were a standalone box https://youtu.be/miimcC2Sr-g
09:47 AM LilyFaith: I didn't take pictures of the controller at all. I will do that this time
09:47 AM cradek: LilyFaith: take pictures of any control panel stuff too
09:47 AM LilyFaith: There is NO PC
09:47 AM gregcnc: this co does upgrades
09:47 AM gregcnc: just a little box?
09:47 AM LilyFaith: No. Its a huge console
09:48 AM gregcnc: yeah, not a PC in there?
09:48 AM cradek: if it really is from the 70s there is probably no CPU and it's a controller made of discrete logic in a box as tall as you
09:48 AM LilyFaith: This is not mine but a google images of what I have
09:48 AM LilyFaith: https://www.google.com/url?sa=i&source=images&cd=&cad=rja&uact=8&ved=2ahUKEwit24zMl9vcAhVJq1MKHVI7B8sQjRx6BAgBEAU&url=https%3A%2F%2Fwww.bidspotter.com%2Fen-us%2Fauction-catalogues%2Fbscdslin%2Fcatalogue-id-danbur10010%2Flot-7e725a9a-c716-4da4-95cc-a5da010b31e1&psig=AOvVaw3sH4jYDYh-s1ImsMBvKsHn&ust=1533739654077420
09:48 AM cradek: if it's a little later, there's a CPU on a smaller board somewhere, but of course not anything like a PC
09:49 AM cradek: aha, crt means it has a computer :-)
09:49 AM LilyFaith: That part that says CNC6 is the "controller" or "PC"
09:49 AM cradek: I'll be interested to see more photos!
09:49 AM LilyFaith: It has a Computer in the broad sense of the word. It does not have PC
09:49 AM cradek: right
09:50 AM skunkworks: 8088
09:50 AM skunkworks: ;)
09:50 AM gregcnc: http://www.excellon.com/used-equipment.html brochure for mkVI
09:51 AM cradek: you might be able to replace everything in that cabinet, and leave most of the rest alone, depends how it all breaks down
09:51 AM cradek: you have lots of these to do?
09:51 AM gregcnc: in any case schematics would make this much easier, otherwise you'll essentially need to create them yourself
09:51 AM cradek: very true
09:52 AM LilyFaith: I honestly don't think its even an 8088. I think its a proprietary system
09:52 AM gregcnc: brochure says somethign about sun sparc
09:52 AM cradek: are yours multipsindle like that? how do they do tool change?
09:55 AM gregcnc: http://probeindustriesinc.com/excellon/images/Mark-V-DR.jpg
09:55 AM gregcnc: all lined up at the front of the table
09:56 AM Loetmichel: LilyFaith: a lot of those old systems use Z80 or copycats of that
09:56 AM LilyFaith: yes
09:56 AM cradek: is it all run on air?
09:57 AM LilyFaith: no idea. how do I determine that
09:57 AM cradek: getting this to move under linuxcnc is easy. getting stuff like the tool change and other I/O to work will be where more time is spent, and I'm trying to guess how easy or hard that is
09:58 AM cradek: if it has lots of clunk/hiss noises while changing tools, it's air
09:58 AM cradek: heck the spindles might be air powered, and the drill up/down too
09:59 AM robotustra: year air usually does "pssssssssss... psssssss....."
10:07 AM cradek: heh https://www.ebay.com/itm/Nalbantov-USB-Floppy-Disk-Drive-Emulator-for-Excellon-CNC-6/161986835664
10:11 AM Loetmichel: *hihihi* sometimes this job is pure comedy... boss is out delivering some goods to a customer... he just called and said "i dropped my glasses. cant decode any street signs any more... can someone guide me home with google maps?" so now the coworker has "won" a late shift talking him home on the phone for the next three hours...
10:11 AM robotustra: somobody foresaw this situation
10:11 AM cradek: oh jeez
10:12 AM cradek: that's crazy driving with a phone navigator and no glasses
10:12 AM robotustra: fire your boss
10:13 AM cradek: I never ever travel without spare glasses
10:13 AM cradek: they're in the car, or in my bag if in someone else's car
10:15 AM Loetmichel: cradek: its the same for me. IF i take off my glasses when driving i can still see the signs and will not kill any game accidentally... but i cant say for sure if there is a "60" or "80" in the next speed sign until i on same height...
10:15 AM cradek: haha I can tell red lights from green lights without mine... :-)
10:15 AM Loetmichel: so no immediate danger but finding the route without being able to read the city names on the signs is difficult
10:17 AM sealive: hi all
10:17 AM sealive: Loetmichel, thunder around your home
10:18 AM sealive: LilyFaith, still on ?
10:19 AM Loetmichel: nope, not even dark here
10:20 AM sealive: here it is building up
10:20 AM sealive: Worms is close to shutdown 60l/15min
10:20 AM Loetmichel: hmm, should i close the convertible for the commute home?
10:21 AM sealive: http://www.unwetterzentrale.de/uwz/
10:26 AM sealive: JT-Shop, on ?
10:27 AM LilyFaith: I am still here. Got sidetracked with my day job ;p
10:27 AM sealive: Loetmichel, do you know the new wiki pas as i try to edit the airfoil script
10:28 AM sealive: LilyFaith, im in Germany
10:28 AM sealive: LilyFaith, here is the Help channel https://www.youtube.com/channel/UCmwhCL92ZQRSVqFe3jGwJSQ/videos
10:28 AM sealive: LilyFaith, lots of controller infos there
10:29 AM sealive: cradek, online ?
10:36 AM sealive: im off till later
10:37 AM sealive: but i got the weekly BBQ town
11:00 AM JT-Shop: am now
11:31 AM LilyFaith: Sorry for the delay. I appreciate all your help https://imgur.com/a/l0ohTsB
11:32 AM LilyFaith: I have to step away again for about an hour. But chat is staying opened so I will reply to any questions as soon as I get back
11:40 AM jdh: nice pneumatics.
11:40 AM jdh: I'd get the usb floppy emulators
12:11 PM fragalot: heya
12:25 PM miss0r: evening
12:25 PM fragalot: 'ello
12:33 PM LilyFaith: jdh Why is that?
12:41 PM skunkworks: jdh: phsss. that is the easy way out
12:41 PM skunkworks: LilyFaith: how much are you guy spending on support calls?
12:46 PM jthornton: logs
12:46 PM logs: jthornton: today's log: http://irc-logs.kcjengr.com/%23linuxcnc/2018/08/07.html
12:52 PM jdh: LilyFaith: that is the immediate, cheap, easy solution to your stated problem.
12:53 PM jdh: I'd rip it out, put in mesa + linuxcnc.
12:53 PM gregcnc: if data transfer is the only issue, (control is not dead) retrofit is a huge undertaking for data trasfer
12:54 PM LilyFaith: cool. Whats a MESA and how do I figure out how to wire it in?
12:54 PM gregcnc: do you have machine shcematics?
12:54 PM jdh: but, tool changers, pnuematics, manual control panel, requires time and expense
12:55 PM jthornton: LilyFaith: https://mesaus.com/
12:56 PM cradek: ha found the computer
12:56 PM cradek: soooo much air stuff
12:56 PM jthornton: a 7i77 plus a 5i25 or 6i25 or 7i92 will get the machine control
12:57 PM cradek: the good part is you can keep all of it as-is. the bad part is you can keep all of it as-is.
12:57 PM jdh: heh
12:57 PM jdh: cradek: that is me every day at work
12:59 PM skunkworks: well - bakc in the day that was cheaper.. Hell we had a machine that shared a servo with 3 axis.. (X,Z and B)
02:07 PM LilyFaith: Have any of you heard of "CamSoftCorp" ? Any opinions?
02:10 PM cradek: my opinion is that in your position of needing to do a complicated thing without actually wanting to figure it all out yourself, you're vulnerable to spending a lot of money on a closed system that will be no better in the long term than what you already have
02:11 PM cradek: using open source software that gives you important freedoms is the only way to avoid those pitfalls
02:11 PM andypugh: Pity Pete isn’t here (that guy we keep mentioning) as he is a) In Florida and b) Probably looking for work, in general terms.
02:11 PM Tom_L: he timed out
02:11 PM cradek: also my opinion is that your net connection is not very good :-)
02:12 PM Tom_L: point him to the log
02:12 PM Tom_L: :)
02:12 PM Tom_L: an IT guy would be on that :D
02:12 PM andypugh: (Whereas a lot of us would willingly trade less paid work for more hobby-time)
02:13 PM jthornton: aye
02:13 PM Tom_L: thing about fixing it for someone, the next thing that would go wrong would be your fault
02:14 PM andypugh: One advantage of LinuxCNC (that isn’t often mentioned) is that you can sack your current retrofit and replace with someone else, even if you, yourself, never figure out how it works.
02:14 PM XXCoder: some washington rivers is too hot to fish at
02:14 PM Tom_L: what does that camsoft use for control software?
02:15 PM XXCoder: it gets worse each year
02:15 PM andypugh: I meant “sack your retrofit support guy”
02:15 PM gregcnc: fire yourself?
02:15 PM Tom_L: i've tried
02:16 PM Tom_L: never works out
02:16 PM gregcnc: keeps showing up eh?
02:16 PM gregcnc: hmm who will watch? https://www.youtube.com/watch?v=jSH7T6AhLd0
02:17 PM andypugh: _Somewhere_ there are two little plates that I use to replace the mittors of my bike at trackdays. I made them in about 15 minutes 15 years ago. Now I can’t find them. And if I make some more it will take _way_ more than 15 minutes as I am now much better equipped, and will get elaborate….
02:18 PM andypugh: gregcnc: I fully expect an entire unbiased appraisal.
02:18 PM andypugh: Apparently LinuxCNC now works with SCCNet. This video link from the forum: https://youtu.be/Uk5LZGasb9o
02:18 PM andypugh: impressive speed.
02:19 PM gregcnc: I just watched that. it's fast
02:23 PM fragalot: and it only took 5 takes for it not to miss steps
02:24 PM gregcnc: what were the issues?
02:24 PM Rab: Hot!
02:25 PM gregcnc: oh that's the same guy that put linuxcnc on that Fagor panel
02:26 PM andypugh: It’s serially controlled servos, what do you mean by missed-steps?
02:26 PM fragalot: andypugh: 'twas a joke
04:05 PM Deejay: gn8
08:40 PM jdh: ?
08:41 PM hazzy-lab: ¿
08:44 PM jdh: some pretty serious idling for here.
08:45 PM hazzy-lab: jdh: Yes, I wonder if it has anything to do with the ongoing spam attach ...
08:45 PM jdh: I don't know of what you speak, but I don't generally see parts/joins
08:47 PM hazzy-lab: freenode (and other IRC networks) has been undergoing a huge spam attack for about the past week
08:48 PM jdh: putin troll obvs.
08:49 PM hazzy-lab: there seems to have been more join/parts too, maybe the extra load on the network might be cause it??
08:49 PM hazzy-lab: lol
09:01 PM robotustra: the last thing putin care in his life is IRC
09:02 PM robotustra: the topics usually spam pot raise are about admins of irc servers
09:08 PM roycroft: actually, the spams claim to be about an irc oper, but the person is actually the subject of some wingnut conspiracy theory
09:08 PM roycroft: please don't ask me for details, because i don't remember any
09:08 PM roycroft: but when the spams first started coming about, on another network, someone told me that it was a "fake oper"
09:09 PM roycroft: and i looked up the name and it was associated with some conspiracy theory
09:09 PM roycroft: since i have zero interest in such things i promptly forgot all details :)
09:22 PM jdh: I can tell.
09:37 PM CaptHindsight: "We hit 500°F in under a second" https://www.brava.com/
09:37 PM CaptHindsight: what hits 500F in a second? A flame will do that in <1 sec
10:23 PM Laminae_: Hey guys, i think i'm nearly out of the woods
10:23 PM Laminae_: My axis' all move as they should in terms of direction and speed
10:24 PM Laminae_: But i have to drivers and steppers on my y but i can only seem to get one working at a given moment
10:24 PM Laminae_: I'm using a 7i76e and i have verified all components individually
10:25 PM Laminae_: And everything does work, jus tnot if i say step gen y on both of the controller outputs
10:25 PM Laminae_: Any suggestions?
10:28 PM Laminae_: Disregard
10:28 PM Laminae_: I'm a moron who can't read
10:28 PM Laminae_: tendem stepgen
