Hi,
I am moving an existing working configuration to a new computer running Debian 12 and a newly downloaded version of LinuxCNC.
The Gmoccapy sims open fine, but I get an error attempting to open my configuration.
The message appears to reference Python, so I have attached copies of the .py files from the configuration Python folder and a copy of the report (linuxcnc.txt). I have also attached a copy of the .hal and.ini files in case they are relevant.

I wonder if perhaps there is a mismatch of the old Python files and the new LinuxCNC?

I would be most grateful if someone could please take a look as this is out of my depth!

Many thanks,
Dougal.

Kannst du bitte mal deine hal und ini Dateien anhängen?

Hi,
ich habe einen ältern Gleichstrom Drehzahlregler der ein Rechtecksignal zur Drehzahlsteuerung benötigt.
Signal passt auch soweit und durch manuelles ändern des Parameters pwm_frquenzy kann ich die Drehzahl ändern.

Jetzt bekomm ich es nicht hin,  diesen Parameter mit der Spindeldrehzahl zu verbinden.
So habe ich es versucht:
net spindle-speed-cmd-rpm  => ...pwmgen.pwm_frequency

​​​​​​Jedoch kommt immer ein Fehler, dass der Pin nicht bekannt ist.
​​​​​​Wie kann ich das Problem angehen? 

Danke 
Viele Grüße
Manuel

thank you very much , I will go try that ASAP

It's not that the motors stall during acceleration. The run for like 50mm normal. I try to make a video. And the weird thing is, it works with the parallel port. I can switch back and forth between the Tang and the parallel port.

use the 'show Halconfiguration' tool to find the correct pin name (something like 'qtplasmac.somePin')

is it maybe too high of an acceleration value? Even not connected to anything steppers need a slowish ramp up compared to servos.

Not sure what the easiest path is here but I see a couple options:

1. With pncconf, make a normal step/dir 7I76E configuration and a normal 7I77 configuration and merge them

2. Use pncconfs discover option

You are awesome! Thank you!

That was the final thing stopping me from continuing the retrofit.

After increasing the FERROR and MIN_FERROR in the ini I have tuned the X axis. I will get the Y and Z today.

now that we have checked my firmware, how do I blend my hal file for the step and direction on the 7i76e

I tried this but I got an error like
./my-mill.hal:57: Pin 'somePin' does not exist

This is not correct syntax to connect two pins in hal:
Correct syntax is (<= and => are optional and are only to improve readability)

Hello to all.
I'm trying to build a custom GUI with pyqt5 for raspberryPi 5.
My linuxCNC version is 2.9.3, python version is 3.11.2.

I wanted to watch a input pin status whenever it changes.
I create a net in my hal file.
After I created this net, I can see the pin and its changing logic from hal show with axis GUI.
I examined the qtplasmac_sim_handler.py and tried to make connections as on it.

Here is my custom GUI's handler file
with this setup I cant see any changes. It only fires one time "Changed", and after that there is no information...

My guide qtplasmac_sim_handler.py did like I was...

What is my fault?

Basically the issue is that the RPI4 Ethernet interface is connected via USB
and USB is not suited for real time.

For a RPI4 I would use a SPI interfaced device, The RPI5 (or most PCs) are fine with Ethernet
LinuxCNC motion controllers because their Ethernet hardware are not USB devices.
