      I'm trying to get a hobby servo working. I've connected signal to the pin marked Fan2- and the +ve -ve to pins 1 & 2 on the expansion header.

      When I power on the board, the servo moves a little, so it seems powered and its only a small r/c hobby servo, which runs fine from low voltage.

      I then send gcode: M106 P2 I-1 followed by M280 P22 S100 (for example) and the servo doesn't move. I've also tried M42 P22 S100 - but no joy.

      Am I missing something?

      I've updated to firmware 1.17 a and its updating the M280 code. So not sure what I'm doing wrong.
