@zizixa Im using Robo 3D R1+ with marlin 1.0 (stock)

If I move the head to the conflict zone, I can extrude normally using +E ( to verify the motor cable its ok at that end)
The problem occurs on the needed print ,
Prints fine till it gets to the left margin.
here the short video

Thanks!

hello all
i started having an issue with the extruder motor , but only occurs on one side of the bed
on the left side margin ,
the other part of the bed prints perfect.
the motor tries to extrude and retract ad rrrrrrrrrrr noise
but when it moves , to a "good sector" prints fine
Ive checked the motor cable and its fine
I think there is some kind of bug in the G Code.
I have a very old Merlin Firm
I need your help, Im printing PPE to help my town
Thanks!
