@droftarts when I try to change the settings as you suggested the "home" command doesn't trigger any more the endstop sensor. so I cannot change the driver mapping configurations.

BTW, is there any way to record the errors even after a reset or power down for further investigating?

thanks
ciao

@droftarts hi, i've thought to swap motor vs. driver it would be just a matter of physically connect the motor to a different driver and set it accordingly into config file. so I've moved to driver 4 and set in the config the following (driver nomenclature having "base 0")

M569 P0.3 S0 

but id doesn't work... what am I missing??

thanks
ciao
Andrea

@droftarts very good idea!! Thanks!!!

thanks for answering!!

the motors are directly connected to the metal frame, that is grounded.

the board has a small fan ventilating the surrounding ambient, I've thought it could be a problem for long running prints, but no error in console appeared once the motor driver shut down. the print keep working without sending out any warning (that's what puzzled me) without the motor.

the only thing I could add is that: when I've tried to home the axis (recall it is a corexy printer) one motor only worked and I've got a warning message in the console suggesting that maybe there was a bad motor connection. but i'm sure no connection issue. anyhow, once I've sent the M98 command everything turno to be up and running again.

I'll move on and "improve the cooling" of the board and let you know.

thanks again for your kind feedbacks!!

ciao, Andrea

if I send a "M98 P"config.g" the driver come back "on", what can it be? in the middle of a printing process this is a mess!! thankss

hi, I've tried 3 times to print a long job and all the time somewhere in the middle it fails. I've thought is something wrong with the slicer parameters but while watching the printing process I've noted on motor axis stop moving (it's a core XY printer).

I've paused the print and checked wiring, connections, possible shortcuts but nothing. all drivers work fine except one. If I try to jog the axis the motor connected to "drive 0.1" doesn't move.

here the output of the M122 comand (the printer is still in pause), the faulty driver is the "driver 1". I cannot figure out how to "re-energize" the driver... I must deliver a big print beginning next week and I'm stuck with no clue how to solve this, if someone can give me some advice... thanks

@dc42 thanks again!!! to me this topic is clearly solved!!! thanks for your time!!

@dc42 you are (obviously) right... I have wrongly connected the sensor wires.

now it's fixed!! thanks!!!

just one more question: if I want to have two "z" sensor, one for bed leveling and one for "safety", is it possible? do you have any recommendation (maybe it's not useful at all)?
