Hi. I’m trying to get my Lowrider SKR 1.3 working with inline laser power. I have it working just fine with m03/m05 commands, but the m03 delay is causing engraving issues. I am using the fan control pin and the 4th servo pin. I have a jtech 7w laser.
My issue is that after enabling inline control, during any movement of the maching fan pin energizes and the laser turns on. I have to manually turn the laser back off when the machine has stopped moving. This includes homing or manual move commands. This makes it impossible to engrave, as the laser can only be toggled off when it is stopped and will immediately turn on again during a move. I don’t know what is causing this behavior.
With inline commands you just have to tell your laser software you are using it. G00 does not turn it on G01 does so the software knows to use them. old gcode will not work with new inline commands.
The laser will turn on wether or not the board is connected to any software. This includes homing the machine before running any gcode commands.The simple act of making any move at all will cause the laser to turn on.
