I have klipper firmware running perfectly on my rolling plotter now. It solved my servo problem of staying in sequence with G1 gcode drawing sequence. I created a G10 & G11 macro for the pen down & pen up movement. Klipper even allows Multi-stepper axes to use separate stepper driver for each motor which I was also doing with the Marlin firmware. I have one bad bearing to still resolve which is noticeable in the video. F695zz flange bearings have worked the best for me & I just realize I have them on my folgertech Delta I could borrow for a while. That is why the one side is not rolling properly in the video. I still have the TPU 3d printed belts on there, but should be able to test the real belts later in the week. I am letting the belts sit in the shed for a few days before trying them.
