Stepper Driver Port broken how to chang the Slot on Octopus F446
Hi, I just finished again a RatRig 400 but my Motors never run well .
After a lot tries and different steppers i get all running until one Motor , after trying switching Motors / drivers I tired the board also in an Running RatRig 300 with the same issue . So all looks like the Stepper driver Port is broken .
Next days will Test the board from the 300 in the 400 but so long i want to try to change the slot of the stepper Driver .
Does anyone tell me how to do it ?

Which motor do you want to switch (A, B, extruder, or one of the Z motors)?

in the USER OVERRIDES section:
you will need to replace those with the new stepper port you are using (see https://raw.githubusercontent.com/bigtreetech/BIGTREETECH-OCTOPUS-Pro/master/Hardware/BIGTREETECH%20Octopus%20Pro%20-%20PIN.pdf)

I bet that will work
obviously make sure you have the correct jumpers set on the motor port as well

i removed all jumpers until the one who need to stay ( secon from down)
taht issue i get often befor the slot broke down

the same troubleshooting steps should apply - could be a bad driver, bad wiring, bad power, etc.

tried 2 drivers just now , rest of the printer was running just bevor i switched the board ( same board so i could double check the issue)
Did you check the wiring to the motor?
