Recently got the Cetus3D MK3. I am trying to figure out how to toggle the external laser pins as shown here
From what I can understand is that these two following gcode commands should toggle the pins:
Laser Off Command: M42 P15 S0
Laser Print Command: M42 P15 S1
When I upload a .gcode file containing the laser off command using UPStudio, the pin stays HIGH. (Measuring with a multimeter gives contant 5 Volts)
Is this guide outdated or am I missing something?
Thanks for reading
