Post Stepper moves more than it should
on: March 13, 2017, 16:22

Hello,
i use a elegoo uno and a v1 motorshield.
when i move the gondola in the controller app a little deeper than the homepoint. the steppers move very long time. it is the correct direction but about 10 Times more than it should.
changed the Steps per Rev from 200 to 20.
now is the moving distance correct. but now i can only draw 9 big pixels inside my frame.

i think there is some trouble with my libary´s
