Hey guys.
I am tinkering arround with an retract problem. I just switched the coupler against an better one, slightly longer one and i had no more retract issues. The coupler was wirh the printer. Pushed the ptfe tubes in an wrong angle together. Eitj an quality pneumatic connector they are perfectly aligned, and it is no more friction there.
Hi @Michael_walk, could you please share which connector are you using now?
