This is great! Thank you! I've been running it on Wine on my linux machine. Playing around with my printer as a pen plotter. G90 as the header for absolute positioning. G1 Z0 as the laser on command to draw and G1 Z0.7 as laser off command to pick up the pen. Obviously using 1-Bit color. Would be so cool if it could use cross hatching to emulate a kind of grayscale!
