Tormach Mill Simulation (770MX): No Way to Take Out of E-Stop was created by linuxdevice

Tormach Mill Simulation (770MX): No Way to Take Out of E-Stop

Category: Basic Configuration

I just installed the default LinuxCNC Debian 12 to a dedicated desktop PC. There is a Tormach 770 PNC configuration available without anything special, and I've loaded that (though I am working with a 770MX, it is not connected to this computer). I am not a machinist, and I know very little about LinuxCNC, although the Tormach PathPilot is derived from LinuxCNC. From what I can tell the 770 PCNC configuration should work, and it sort of does. I can load a simple g-code file which I've used on the 770MX, and it shows the same graphical display as the actual 770MX (I also imported the tool table from the actual Tormach). The problem: There is no way to "run" the code.

I'm attaching a screenshot. You can see it is in E-Stop, and the buttons I think are for starting cycle (which is unclear if those are for that purpose) are grayed out. Menus do not have any way to take this out of E-Stop or reset. Maybe there is some added setup needed for this to be a simulation without hardware? Any suggestions on what to look at to make this run like a PCNC 770 from Tormach?

Machine stopped in middle of program.

Category: AXIS

-power brownout
-lighting strike even several miles away
-processor had a hiccup
-failing power supply
-failing memory or memory controller
-failing capacitors on PC
etc
If any of the last 4, the issue will occur more often with time.
If the second, not much you can do.
If the first thing, and if this is a parallel port setup, and this happens again, see what equipment did you turn on in the house/shop/neighborhood, as big power draw equipment can cause this, easily, and they do for sure cause power brownouts.

Machine stopped in middle of program.

Category: AXIS

Greetings,

I was machining two parts that I have run before at least 30 times.

First part machined as expected.

The second part got 3/4 through the program and the spindle and axis motors stopped.

Also, the AXIS screen was frozen up. No response to keyboard nor mouse.

I turned off the power and rebooted.

Next I started LinuxCNC 2.5.5. All went well.

Reloaded the program, dialed the part back in, and reset Z zero of the cutting tool.

Pressed Cycle Start and the program ran fine.

So, what happened?

Is there an error log/file I can look through to determine the cause of the shut down?

More clues.....

Cheers,

Dave

What are the chances of getting this setup working?

Category: Pick and Place

Well with my project I got interested in other things and haven't spent much time on it in a while.
Partly the placer head desperately needs updating to modern day equipment. Cable and pulley
for the Z axis is in my opinion a terrible idea but the machine was designed in 1993. We have a few
other PnP machines where I work so this one was more or less an experiment. Plus work just
doesn't seem to ease up.
 

I tend to post and then forget about LinuxCNC for a few weeks lol, forgot to check on this. I just converted the machine I intended to be to a laser cutter.....since I needed one and figured I could actually get that going. I had a belted see-saw Z, which I just stripped to mount the laser to the carriage.  I did redesign it to be a rack and pinion see-saw so that way I could easily swap out the PnP nozzles for and the laser and have a compatible Z. I haven't machined it yet though

It'd be nice if there was a proven simplified PnP setup for LinuxCNC. I'd be alot more inclined to finish the mechanical stuff if I knew software wasn't going to be a long drawn out slug fest. Hopefully somebody beats me to it, if not maybe I'll get there one day lol.

I do find flexGUI to be a pretty easy (ish) way to get a purpose built UI going. I was able to convert the one I was making for my mill into a laser UI fairly simple. I'd definately use that to tackle the PnP thing if I were at it right now.

Whoa, hold up.

Households in Austrailia use 415VAC?!

(little kid): "Hey daddy, what's this? ...kzapp! [kid gets electrocuted]"


 

Haha, I wish.

Some have 415 3ph, but normally we just have 240v single in houses. Most single phase outlets here limited to 15amp, even in industrial settings (high amp ones do exist, but aren't as common as high amp 415 3ph). Hence, I'll need 400v 3ph drives as that's the high amp I have available in the shop.

I assume the procedure is similar for newer drives if running analog?
Yes.

I would tune the velocity/torque in the drive software, then tune position through Linuxcnc.

Yes.

It looks like a few of the modern servo drives I've looked at have encoder outputs. Those will just run back into a Mesa card like the 7I97?
Yes.
3 for 3, nice! :)
New drives can also be controlled by step/dir and also have encoder outputs, and those can again be used in LinuxCNC.
And there are several boards from Mesa that can be used, not just 7i97, a lot of combos there so when you are ready to order stuff, ask here first as we have the Mesa Master with us here, always, in the form of PCW.

Ace! Thanks Tommylight.

I have a 7i96 kicking around from a machine that never got off the ground, but I assume the lack of encoder inputs means I should use a different card.

This machine originally had rapids of 32,000mm/min with 16mm pitch ballscrews - 2000rpm on the axis. Would there be any benefit of analog over step/dir or even ethercat, to maintain such rates of speed and precision?

I just got off a 10hr flight. I took the original Bridgeport machine schematics with me to asses the control side of things. It looks like the Heidenhain output a 24v (sourcing?) signal to a bank of relays to control the solenoids, enables, mag motors, contractors etc. I assume a Mesa card, like the 7i84U could take this role?

It'd be bloody awesome if I could just retain these original distribution/control boards and halve the amount of wiring required!

Yes,

programmer pinout is:

Sorry I could not get the remote update working with

QtDragon_hd + Basic Probe - probing results not displayed

Category: Qtvcp

I've took additional measurements using the debug mode and terminal output. Attached is a video containing two following measurements.

In the first measurement, the feedrate value was constant throughout the probing. In the second measurement, the value was deliberately changed by feedrate potentiometer.



The terminal output shows that in the second measurement, the following lines were added:
[DEFAULT.QTVCP.QT_ACTION][DEBUG]  CALL_MDI Command: G91 (qt_action.py:182) 

The command M64 P4 at the beginning and M65 P4 at the end were added and are necessary for "turn on" and "turn off" of my probe.

Terminal output also in attachment:

Oh, interesting.
So do I understand right - it should work when I find a PIC programmer that can program it? I guess that should be doable.
Is there a pinout for the programmer pins?

best regards & thanks for your support,
