i3 Prusa Acryl Pro b - motors not working
Posted: Mon Sep 28, 2020 4:50 pm
Hallo guys,
My Prusa i3 Pro B has M8 and a new and stable PSU.
Actual Supply: 13V in the PSU.
I measure on the motor drivers 5V. I tried it with inverted Dirs but no sound of the motors or any movement.
I could not measure the 12V between the additional motor (1. Pin Black) and and the ground of the fan as described in the tutorial for the board.
I think I watched hundreds of videos and googled quite a lot but nothing worked.
I think the motors dont get the 12V
Can someone help me?
