Hello kalgula20,
There is also too little powder when aligning. I’m already going for it myself. Can I set that somewhere?

Try FILL_BED_SPREADS 35 command in .ini file. But I would guess that the platforms are misaligned or maybe roller in not spinning right or too much powder is getting out of the build platforms on each side. Don’t really know if there are any settings for powder dispensing since this is not the automated system like 650/660.
