I'm upgrading my laser cutter / etcher. I've installed a RDC644XG controller and Leadshine DM442 drivers. I'm having trouble controlling my original Smooth type 17HA507H-22P2
and 17HA507H-22A stepper motors. These are 0.9 degree motors, The instructions for the Leadshine drivers refer to 1.8 degree motors. Can anyone advise as to whether my best move
is to upgrade my stepper motors. I laser etch I'm not concerned with speed but with accuracy. If a better move is different drivers and motors I'd appreciate suggestions.
Having a reliable and accurate machine is my aim. Thanks
