The last few nights have been spent printing parts for yet another MPCNC build, and while printing I have been scouting for motors and other hardware. I came to think of the dead-weight of the moving parts; what - from what I understand - prompted the Bowden Tube invention.
Would it be possible, or even a good idea, to move the four steppers for the X and Y axis to the four corners instead, and fixing the GT2 belt to the carry? The dual steppers alone contribute to 700g for each axis of weight/inertia that the motors are required to push around.
Am I missing something? Does the extra belt (more or less double the length) add undesirable properties?
