Hi, I had trouble shrinking the pic to send. Anyways-
Spi seems to have never been flashed nor working... my memory fooled me there so sorry for that. I rebuilt the lpt to p4 cable as i had that wrong as well....
But now... still no respone from Mesaflash version x.11 (within lnxcnc img 2.9.4). With jumper w3 i can seemingly select two configs under halrun so both eeprom seeem good.
Both are working under loadrt in epp.mode but none with Mesaflash.
For that i used sudo mesaflash --device 7i90hd --epp --addr 0x378 --verbose --readhdmi
I also tried --addr 0x778
I did try --addr_hi w/o anything added as not sure how to use it...with --addr
I tried many comies - nothing but No 7i90hd found.
Or syntax errors...
I will post the response from loadrt later as it provided some interesting response reharding the interface - matching the comand line in mesaflash but having some more info - cant recall right.now ...)
The lp0 port is confirmed in the boot log ... epp 378 int 5 etc.
under halmon i check some io's and they are updated in linuxcnc. When i short inputs it is visible. at least it seems to work on that side...
Messig about i also get the watchdog bite.
So whats left that im doing wrong
Thanks so far..
At least im a bit more ahead now what to do and check when going for spi... may be... as id like to have it on a pi5...

Its interesting your feedback about motor performance. I di wonder about how I would go not using Lichuan motors. 3000 rpm is up where I was expecting!
I've had a change of pace and been doing some CAD cos I gotta use these things! Slowly coming together with a scrap of gear rack I had lying around.

If you are going shopping for power supplies, Lichuan recommend to use 36 volts. I bought a nice little 5 amp din rail mount one which will do my 2 amp motors.. I meant to get 36 volts but force of habit I bought 48v!It can be that the motor speed needs to be ramped up, like it is by linuxcnc.
Setting 6000 rpm as a step is quite challenging.
Anyway, 3000 rpm is more than decent for a stepper motor.
Consider to use csp mode, that's what most people do.
The position feedback is lagging two servo cycles when using ethercat
and a velocity loop has a hard time.
If you use csp, the position update will stop in your scenario, and the motors will stop.
Check out the SDO listing, there is a max current setting (per motor).

Hey Guys,
a few hours later, i compile a new mbccs file and implemented these pin names in my .hal file.
I can toggle the pin in LinuxCNC but still no reaction on my Vdf.
There is a little RUN LED on top of the VDF to indicate, if I successfully send the "run" command.
(It worked with the USB-Dongle pretty well)
Can you see any kind of mistakes anywhere ?
I am close to the finishline but getting more and more frustrated
Thank you for any hint
