Been testing my ATMega256 marlin laser engraver with pronterface, and all the motion commands work, and things like G0 S200 X60 Y60 will move the head and also activate the laser for the entire motion. Great. I put the same in a gcode test file to run from an sd card:
G1 S200 X100
G0 S200 X100 Y60.333
G1 S200 X0
G0 S200 X0 Y60.667
G1 S200 X100
a simple back and forth scanning pattern ... and the laser blinks every time the command changes - that is, when it changes direction, I see the laser flash briefly - but for the rest of the time the laser is off. Why might this be?
Not sure if this is related, but I can also manually turn the laser on with M4, but then any motion immedialtey turns it off again.
Appreciate any advice or things to try! Can also provide more detail and context if needed, apologies if this was not enough.
