Dear sir
Thanks for answering
Well, in the beginning I had the same idea.
But I didn't find out how to configure the second stepper motor for the other z axis on
https://configtool.reprapfirmware.org/Start
It shows me just X, Y, Z, E1, E2, E3.
I would definitely be interested in finding the solution of this issue and absolutely pleased if you could help me. Leading through my problem.
Thanks a lot in advance
Best regards
Joel
