I have recently assembled a XY-PlotterV2 and I seem to have a problem with movement along the Y axis. If the DIP switches on the Me stepper driver are all low (default setting), the movement in the first half of the Y path is smooth and linear, but in the second half it becomes “jumpy” and the whole plotter starts to shake. I tried tightening the belts as much as possible, didn’t help. Any suggestions? (Should I increase the current on the stepper driver? Should I always use slower settings on the DIP switches?)
Furthermore, I cannot seem to set a zero position for the servo, that controls the pen holder, is this even possible? Or do I need to adjust the pen to be in the right position, depending on the height of the surface I wish to draw on?
Lastly, I also have the laser upgrade for the plotter and since I want to use both the laser and the pen plotter function, is there a simple way to switch between firmwares?
