Maybe just a short update without pictures :

Here you can find the schematics with guide ... i think there is only one mode useful and this is a
16 usteps to 256 usteps Interpolation in the spreadcycle mode.
This can be reached through CFG2 open ( desolder the resistor ) and CFG1 set to GND ( Low ) ...
The original steppers are configured to ( High, High, High ) for all motors for 1/16 Steps except the Z-Stage, the Z-Stage is configured to ( High, High, Low ) for 1/8 usteps ......
That means if you remove the Jumper from MS1 .. MS1 and therefore CFG1 is set to low ....
Regarding the motor cable :
If you look at the cable you can see the following color ordering :
Blue, Red, Green, Black ....
You just have to change them to
Green, Black, Blue, red ...
And by the way ... i set the voltage reference to 1.25 Volt which should lead to about 0.88 A .... first i set it to 1.2 A ... but the steppers were running with about 70° C ... now they run with about 50° C .....
Currently i print a big, red elephant for my daughter ... it is running already 8 hours and if everything wents fine this will be a 30 h testprint .....
I think after that i will know if everything is stable
