Sorry for my poor English, i am french

I have bought a A10M 3D printer, and i had te replace the motherboard

I just want to print with the extruder E0, and it turn very very fast !!!!! The extruder E0 works perfectly. I tried to switch the cable of extruder E1 on extruder E0, and i have the same thing. If i plug the extruder E1 motor of the output E0 it is ok ….

I had checked voltage of stepper and every thing is ok

If i try to miw, and i adjust the percentage of Extruder E1, the Velocity change

I would like to know if there is a probleme with the card or i have to modify a parameter


Help me pleaseeeeeeeeeeeeeeeeeeeee

I finaly find the solution :

Under the stepper there are connectors and there are 3 jumpers. On my board Nothing …

Now the extruder works perfectly
