    First movements......

    Sorry I don't have any pics now. I was able to make my first movements on my machine yesterday. It was the coolest feeling to see it come to life. I learned some lessons while I was at it too. The first lesson came by getting a better understanding of Mach 3. My second lesson came when I tried to move the X axis. I spliced the cables for the dual drive R&P steppers but found out that the two motors wanted to go in opposite directions. Rewired and separated the two motors and made the A axis on the G540 a slave to the X through Mach3. Still wanted to go backwards of one another until I reversed the wiring on one motor.

    I also learned that to drive 4 motors that I need a bigger power supply. Never could get my Y axis to go until I attached the cable to the A port on the G540. After turning everything off and coming back later I did get the Y axis to move, but only until I moved one of the other axes. That's when I thought it through and studied it to find that I need a 48v 12.5amp power supply.

    So far I'm pleased.

    No need to rewire motors if they spin the wrong direction. Just reverse the pinout setting in mach for that axis to active high or active low.
