So a few hours together with an additional set of hands and eyes (ok and 2 bottles of wine),

so we readjust the belts and checked the X Motor again ( alone I think never check him again bec checked befor mounting)hr was running much to strong.

So changed motor readjust all belts and all pololus (Voltage around 250-260mV)

Adjust the Printbed and start first print.

Result not bad for the first print Block 20x20mm result 20,1x20,15mm but with a lot of missing steps in Y ( My Mistake Y has 2 motors so need to use a bit more Power)

I also cuttet the cover a bit so I can remove it everytime.

So today finaly adjust Y Pololu and change the firmware

In the Firmware I ´ll change the max width for X looks like here is in the single Extruder Version also the value for the Dual inside so can not use the full 400mm range
