From your videos it looked to me like you were experiencing non-deterministic data communications errors between the computer and your DSP controller. The errors seemed to be different each time you tried to print. If it were a controller firmware or data formatting problem I would expect the errors to be repeatable.
Are you driving this via USB, parallel, or serial port? Are there options for communications speed, handshaking, and buffering? If you can slow things down with proper handshaking you may be able to get the data down to the controller successfully. If it is still messing up but consistently, you probably have servo drive speed and acceleration setting to adjust, as well.
I was very impressed with your improvements and modifications. Did you increase your cutting area or was that the original size?
Best of luck,
