Custom Drive System
At the moment I am experimenting with ways on how to overcome the drawbacks of H-Belt (racking of the gantry, uneven belt tension) and Core XY (long belt, belt crossing or belt in two planes)
My design is actually just a modified version of the Drive System used in de MarkForged Machines. It consists of a nornal H-Gantry that is driven in the Y-direction by two closesed belts on each side of the maschine (blue). The belts are connected via a motor driven shaft to keep both sides syncronised an prevent any racking of the gantry. The X-Axis is driven by the red belt.
In order to move the X-Axis the X-Motor rotates clockwise or anticklockwise to move the carriage right or left. Nothing fancy here...
But to move only the Y-Axis up and down, both Motors have to works together.
So I am trying to figure out how to setup a custom drive system for this in Repetier.
Any help would be much apreciated !
