Question, does it normally take 2 hours to flash tangbob board?
Using the example config file.

Thank you

Moving from Axis to QtDragon? was created by Spyderbreath

Moving from Axis to QtDragon?

Category: Qtvcp

Hello all. Completely new and ignorant to this topic, and after more than a little searching I have not found any answers.

I currently have a Remora/NVEM configuration working under the Axis interface and would like to move that into QtDragon. However, that is not a simple cut and paste operation, and I can not find any guidance on how to even begin to attempt it. Just looking at the differences between the Axis and QtDragon directories has me confused. They are not the same.

Any help or guidance would be appreciated as I am at a loss to find a starting point. I can certainly provide my .hal and .ini files if needed.

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

Category: Basic Configuration

This is entirely for simulation. I'd like to see how things work on the simulation prior to putting g-code onto the actual Tormach. It makes experimentation safe.

So far I have used the provided files which come with the LinuxCNC install:
~/linuxcnc/configs/by_machine.tormach/pcnc-770.*

It sounds like "~/linuxcnc/configs/by_machine.tormach/pcnc-770.ini" is where to look. I'll dig around in that and see if I can see what you are mentioning. Thank you!

PS: That file is a copy from the reference copy already, but I will make a backup anyway.

It is unclear if you are setting up this to later be wired to the machine, or this will be simulation only.
Either way, the limit switches are triggered or missing if not connected to machine, so if you want to use it as a sim, remove or omit the lines containing limit switch inputs in hal and lines with home-something-or-another in the ini file.
Do make backups of the original config, though.
And you can have as many configs on the PC as you like, so feel free to make copies, edit and test, to your hearts content.

Wonderful. Yea, I don't think I would of gotten that spindle config. Thanks.

And I think my next and maybe final question for now is when uploading the .txt file to the controller, does the upload script need to be run in a virtual environment or can it be run from a standard console?

I ask thinking about changing to the DMAstepgen from the basic.

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.....

LinuxCNC 2.5.5
Smithy 1240 Milling machine

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!
