After the compression the video doesn’t look great but you should get the idea. The actual motion does look pretty smooth in person. Please note that it sounds great at the beginning as the machine homes and sounds fine as well as the pen picks up and moves to another location. Nothing is getting drawn because I purposely increased the z position to rule out issues related to the pressure of the pen on the table. I measured the distance of the basic single axis lines and they were pretty much perfect so my dimension (and hopefully the rest of the motor settings) should be correct.
