Hi, It turns out I had to reset the power on the device every time i tried a different config.
Suddenly it started working.

finally got the thing spinning with with my new hardware

I also have a 7i95T card and I have a problem with the configuration. I don't understand your procedure at all...
Please write the most detailed procedure for activating the script and attach the script - I would like to use pnconfig on linuxcnc 2.94.

Thank you

Hi, I'm trying to put together some Beckhoff IO module with ethercat.
I followed the examples and instructions i found on this forum but I can't get my EK1100 to go into OP mode.
I know my ethercat setup is good because I managed to get a servo drive working through ethercat.
Here's some outputs:

And my config:

ethercat-test.hal
ethercat-conf.xml
When I run
halrun -I -kf ethercat-test.hal
and then open halshow I can see all the pins but the devices stay in PREOP mode. I can write to the output pins but nothing changes on the drive. The RUN led blinks on the EK1100 confirming that it's in PREOP mode.

This is dmesg output:
Am I doing something wrong?

It appears G10 L2 and G10 L20 assume machine is actually Homed physically, and no amount of data entry can change that.

I don't understand what you are doing. Without homing the machine first there is really no point in setting offsets.

Hello everyone,

I have a strange problem with LinuxCNC on a machine that has been configured for a long time and was working perfectly.

Until a few days ago, everything was working fine. Then I modified my Python Touchy GUI file (adding dynamic multi-language translation using `set_label` on some buttons), and from that moment the problem appeared:

> "joint 0 following error" immediately after clicking "Start".

The problem still remains even if I completely delete all the translation modifications (`LABELS` and `on_combo_language_changed`);


Code I had added:

@cakeslob , I had a look at your hal file again and copied your spindle stuff exactly just changed for my pins etc and it's still the same. So I think that rules out a hal file problem. I don't think it's the vfd because I can change the speed manually by pressing the + and - manually in the  Axis GUI and it responses quick with no dips when changing speeds. 

Went back to Axis.
linuxcnc.var has Parameter #5221 = -238.
Ignoring y and z for this description.
Launch Axis, Display is:
- x238,
- G54 x-238.
This shows G54 x correctly as negative, ( whereas Gmoccapy shows G54 x as positive ).

No amount of Touching-Off, G10 L2, G10 L20, etc, by me gets to the final correct values for a job:
- x0,
- G54 x-238.

It appears G10 L2 and G10 L20 assume machine is actually Homed physically, and no amount of data entry can change that.

For jobs, I turn steppers Off, operate the machine controller to the measured table position, then Touch-Off, energize the steppers, and run the job.

Can anyone provide an alternative procedure to set-up the mill ?

John.

The test results of versions 2.9.3 and 1.6.4 are consistent

Thanks Cakeslob, which board is the H723 being used? This will be a good test to see if we can get PlatformIO working happy with multiple targets. The code will need #ifdef's and compiler defines for each board to select the code changes needed for each H7 variant.

I thought you upgraded your machine to a Hypertherm 45XP or similar.
If that is the case, please use the Arc OK output on your plasma cutter as it will save you issues in the future.
You can get the cable (and the interface) for your plasma cutter from QWS in Brisbane

An important aspect to keeping as much smarts in LinuxCNC as possible is that
complex control systems (like plasma control) work on all supported hardware. As
long as  LinuxCNC has enough control bandwidth, its an advantage to have a single
portable extensible and flexible solution with a single control locus (that has access
to all motion variables)

Do you really want to re-invent and maintain a control system that LinuxCNC can
do internally just as well? Buffered systems like Mach require this type of external
hardware, real time systems Like LinuxCNC do not.

 

but in theory, a Grbl component could completely replace the EMCMot+Stepgen components in LinuxCNC for stepper motors signal generation.


Hmmmm ok

OK, this i did not need to read twice, but from it now it seems you are searching for a problem that already has a solution, well several solutions.
The reference to old dumb drives is a bit disrespectful to old drives, they built the industrial complex we call modern ages, and it worked perfectly well for over 50 years.
Still, with a bit of tinkering, you can get a decent stand alone THC, probably using an ESP32 as it has 12 bit AD inputs, it can control stepper motors so everything on the Z axis can be controlled by it, it can do very fast PID loops, and adding void detection is as simple as checking the voltage rise time with delta-V/T or time.
A 3D printer screen with encoder, a nice simple menu, and that's about it.

There was a discussion here about adding controls to old plasma sources to change current from LinuxCNC, but that is not important anymore. Some relays would do the trick easily and some HAL wizardry.
This just shows the flexibility of LinuxCNC to adapt it to whatever is required, hence keeping stuff in LinuxCNC seems much more useful.
And, yes, QtPlasmaC has the ability to control plasma sources through RS485.

All this is in no way, shape or form meant to discourage you from trying to make such a thing, and i would gladly help and test whenever possible. I have plenty of CNC machines and plasma sources and ESP32 and 3D printers and...
