Dual extruders wrong steps/speed

[bicho.cl]

Hi everyone,

I'm having an issue with the extruders of my m201 color mixer.
The steppers motors are moving more than should be, at least one.
When I set the mix 50/50 and move 1 mm using the LCD knob one extruder moves 1 mm, about a 1/16 of a complete turn, but the other moves around 1/6 or more...
Already swap the cables, adjust pot voltage, swap drivers and reflashed firmware, but the problem persist and is related to the port of the extruder 1 in the mainboard.
The printed was assembly about 3 years and was stored without use, this are the first tune on this machine.
Any idea will be appreciated.

Hi.


If you have not yet solved your problem, I have a small hint for you.

The stepstick modules have jumpers for configuring step resolution.
Check if they are equally set and if they are set correctly at all.
