I have an OX (inherited from my father after he passed. Not sure of the rationale for selecting the electronics), with NEMA 23 steppers (2303HS280AW-OB) driven by DQ542MA amps. X and Z-Axis are 1 stepper/amplifier; Y-Axis has dual steppers driven from a single amp. I've finished my first project as a trial, and the x-axis is missing a lot of steps, while Z and Y do not seem to be skipping much to any at all. The X-axis stepper is overheating. After my first project, I'm now working to true up my bed's sacrificial board, but need to solve the overheating/skipping issue first. Not sure if the amplifier is suited for the stepper. Looking for some electrical engineering advice here. Thanks in advance for any thoughts.
