Ender 3 pro new motherboard V4.2.7 stepper do not work
hello to all,
some days ago the stepper driver for the filament transport has broken.
I bought a new motherboard wit the same version (V4.7.2) and installed it.
Now I found out that none of the steppers works.
The heating of the bed and the nozzle works but the steppers do not work anymore.
When I switch the printer on then it there is a short noise like a hit. And when I start a stepper then I got the same noise.
What could be the reason for this behavior?
Must I build and install the firmware again?
Thanks a lot in advance.
