i have here a l298n modul and a mesa 7i92 with bitfile adjusted to have pwm and 2 gpios for setting direction.

You could start by having a look at the "etch a sketch" config included with LinuxCNC, it is for parallel port so needs changing pin names to Mesa, and it is for L298.
Probably doing some timing stuff in hal using timedelay and/or oneshot and maybe flip-flop ....

Reading something today. Maybe try using smp affinity to lock the USB interrupt to  Core1 (away from core 0 housekeeping) and assuming > 2 cores. You can find the interrupt by
cat /proc/interrupts | grep -i usb

Then follow one of the many posts about cpu affinity for networking. Just remember you need to reset this on every boot.

I use "dark reader" and since 3 days ago it does not allow me to reply to anything here without disabling it.

Yes and no, sorry my bad, i thought i uploaded the new config there, so thank you for reminding me.
I did upload the new config there and added some more info at the top, so have a look at your own leisure.
These are also new machines i have built and use the same configs for PWM and here i did upload the new configs.
forum.linuxcnc.org/show-your-stuff/46752...ver-etcher-scratcher

Latest config with provisions for disabling PWM on program pause or stop and enabling on resume.
Edit:
Attached the latest config to the first post, also.

Tommy are you talking about the engravertest.zip?

Ich habe keine Add-ons installiert und das Design nicht verändert. 

Firefox und Microsoft Edge haben beide den gleichen Fehler. 

Was meinst du? 

Sorry but i do not have any file you need, i would have attached them on my first reply if i did.

In the ini file
HOME_OFFSET = -3
for each joint/axis
That is for metric machine, adjust accordingly for imperial.

Okay, so maybe we can conclude that somehow the hardware is not 100% suitable on your "real" setup?

If you still test on the N100, I believe you could force the setupAsyncTransfer error by putting the loops back to original values (or even higher), and jogging while a program is running.

Thanks for the very quick help. Fabex is BlenderCam renamed because of a naming dispute between blender and the author(s) of the CAM add on. 1 week ago I installed the latest Blender 5.0.1 and the latest Fabex 3.0.1 from their official repositories. Due to the famously complex non standard Blender GUI I am not sure I have all the configuration and settings correct. That is why I am looking for a simple .blend file for CNC machining which ALREADY is fully set up to generate GCode.( the resultant Gcode would probably be handy too ). That way I can back check where I might be making a mistake. If you or others have already run BlenderCAM I think any simple/ non confidential file would do the trick.
Cheers and again thanks.

In your archive there are many files, but I can see (as ncam xml files) only the default tamplate.
Please, in ncam, use the menu "Project->Save as..." to save your ncam project as xml and post here.
Are you using a milling machine or a lathe?

I should have stated - the limit / homing, picked off machine, home axis - trying to home one at a time, the axis moves to the limit switch and locks, need to over ride limits, move axis off limits - all axis

Hi David
Did you get running the 2A?
Im own the version with 4 axis and trying to get the right ethercat config.
The name of driver is CL57E-4A.
I will try to expand your example to 4 axis.
Perhaps you can told me, if you get it running?

I have a second driver from Lichuan called OLC-E57H. I will also try to get it running. I think this should work all in same structure (hopefully).

Its critical with multi axis slaves that the xml exactly matches the pdo structure. fire up linuxcnc and in another window, type halcmd show pin cia402* Look for the status word. (or use halshow) They all should have the same value. If they don't your xml is wrong (ask me how I learnt this)
