Unable to send commands to pins over 99 using M42 GCode
Hi, I am running luc-github-Repetier-Firmware-0.92 on a Da Vinci AiO. I am trying to switch one of the spare outputs for LASER1 which is connected to SAM3X pin 138 which in turn is mapped as pin 101 using the M42 commands 'M42 P101 S0' AND 'M42 P101 S255' but Repetier host just plays an alarm sound and I get no response from the printer.

Any ideas? Is anyone else running this setup and can try it for me?
