The prototype for my CoreXY experiment now moves by motor control. Using Marlin software on an Arduino Mega with RAMPS1.4 to drive the motors, I go through several speeds from 800mm/min to 24000mm/min, (that's 400mm/sec) moves. I have made no care to precision in the belt, and adding that to unevenly tightened belts, flex in components, and finally a pen that's not really fastened well, there is noticeable flaws in the resulting drawing. However, this also means the prototype highlights what areas of a final build will need extra attention. This first prototype is based on the CoreXY concept and ideas from FABtotum to avoid crossing belts
