Thanks Jon! ... I had a feeling you would see the benefit in rotating that extruder motor... I jacked my printrboard and am waiting for a replacement... then I will print this. One more thought I am thinking of going to a bowden conversion. To remove all that weight from the end.. Not to mention that It might be possible to add more that one hot end if the motor can be placed elsewhere. Does any one on here have any experience with the bowden conversion? if so ... how has it worked out?
