Hello,

i need some help to configure a Extruder Stepper Motor.
I have a dual / mixing Extruder with these Stepper Motors:

PG35S-D48-HHC2

my configuration is :

; Drives
M569 P0 S1 ; Drive 0 goes forwards
M569 P1 S1 ; Drive 1 goes forwards
M569 P2 S1 ; Drive 2 goes forwards
M569 P3 S1 ; Drive 3 goes forwards
M569 P4 S0 ; Drive 4 goes backwards

M350 X128 Y128 Z128 I0 ;E16:16 I0 ; Configure microstepping without interpolation
M350 E16:16 I1
M92 X800 Y800 Z12800 E1700:1700 ; Set steps per mm
M566 X900 Y900 Z12 E300:300 ; Set maximum instantaneous speed changes (mm/min) / jerk
M203 X12000 Y12000 Z500 E1500:1500 ; Set maximum speeds (mm/min) Feedrate
M201 X1000 Y1000 Z100 E10000:10000 ; Set accelerations (mm/s^2)
M906 X855 Y855 Z855 U855 E250:250 I30 ; Set motor currents (mA) and motor idle factor in per cent
M84 S30 ; Set idle timeout

But this is'nt working correctly..
when i extrude some Millimeter the motor is rotating 1° or 2 °
when i extrude to fast the motor is rotating in the false direction

Can anyone help me ?
Thanks and best regards.

Your E acceleration in the M201 command is 10000 which is much too high. Try reducing it to 1000 or less.
