I have been experimenting with the rotary tool but am having some issues with slippage -- just at the start and stop of the job when the rollers move very fast. This causes my images to engrave fine but slightly off in position. Also this prohibits me from doing multiple pass engravings. Which settings should I adjust in the setup to slow down this y axis "homing" speed? I am using wide rubber bands to decrease the slippage but not eliminate it.
Thanks
