Hi guys,
unfornunately I got no support from Panucatt, hopefully someone her knows what to do.
After reading a lot about the different wiring solutions, which do not work quite well for my setup I thought about a software solution.
Is there a possibility to split the pin-adress for the x-axis? Or will it work by changing the designated axis of the delte driver to X? Or is there a wiring/soldering solution?
Thanks a lot for any support or ideas.

Can you explain what you mean in more detail ? I’m a bit lost what the problem is.
Okay, my setup is the following:
Board is a Panucatt Azteeg X5 GT 32bit Motion Controller with SPI-controlled Bigfoot-Stepper-Drivers. 24V with 3amps.
My OX CNC has NEMA23 steppers with 24-48V and 3amps. The x-axis has two of these steppers.
Because the drivers don’t support enough power to wire two steppers in serial or parallel without losing significantly on strength and accuracy, I would like to use a driver for each stepper. I read the existing possebilities in the general appendix but my drivers get a SPI-command, so I’m not sure if a similar wiring solution exists. So I thought of a software solution. My idea was to change the etruder driver to the x-axis in the config file.
Yesterday, my first idea was to change the
motor_driver_control.delta.designator X # D to set the settings
to the x-axis, but I wasn’t sure how to change the rest of the config.
After having a closer look on the config file today, it seems to me that panucatt delivers a pretty “mix’n smash” config file, setting up polulu and SPI drivers simmultaniously. But maybe this has to be and I missunderstand the config.
Can you understand my problem now or is something still unclear?
Thanks for your help
I feel a bit uncertain with my current solution, but if nobody predicts a fail I would give it a try tonight:
pastebin . com / vriE6Axt
So today I gave it a try.
Did not work out. The second stepper didn’t move at all. Any ideas what to try next?
I thought of soldering a y-cable for the needed pins and replace the pin-connector. Similar to this renedruckt.blogspot. de/2016/02/schrittmotortreiber-passiv-kuhlen.html
The not working config code can be found on pastebin

Ok so.
You need to understand there is no link between axis movement and driver configuration. You can do anything you want in each.
So just configure each driver for whatever current/parameter you want, completely ignoring axis assignment.
And then configure each axis to use whatever driver you want ( by changing step/dir pins around )
Ok, I think I get something wrong. There is no x-axis-dir-pin , instead aplha, beta… or is in my case the 0.11 Pin the x-axis direction and this can be assigned to multiple steppers like:
alpha_dir_pin 0.11!
delta_dir_pin 0.11!
The same question occurs to me in the jogging parameters where alpha - gamma is defined.
Is there any wiki article to get more information about that?
by default, alpha is X, beta is Y, etc, but you can change whatever you want to whatever you want by changing the pins
