Direct Motor Control

Method 1 Debug Port:

ODU>motorcon
MCON>run
dcmc >?

Method 2 PCB Port:

  • Board revisions from 2016 on have a TTL/UART port next to the main processor labelled "MOT". Solder on header and connect with 57600 baud and you will be in the dcmc menu. There is no other menu access from this port.
  • Board revisions prior to 2016 have a separate 6P6C connector next to the debug port. Connect to port with 57600 baud and you will be in the dcmc menu. There is no other menu access from this port.

The dcmc > allows for multiple p commands to be going at the same time. So p 0 3300, p 1 0, and p 2 180 controls all three motors at once. Stacking motors in the same command does not work p 0 3300 1 0 2 180 or p 0 3300 p 1 0 p 2 180.

  • First # is motor
    • 0 = AZ
    • 1 = EL
    • 2 = SK
  • Second # is steps
