Hi guys, im new on light burn, i atm use GRBL and it works fine, i want use marlin becouse i see its more stable, but what version i need to put on arduino? and what do i need to change? is there a tutorial about this? sry if someone made a topic like this.
Marlin is not terribly well suited for laser use. It doesn’t have a laser specific mode like GRBL and Smoothieware do, which means that if the head stops moving, the laser stays on, which is bad. It also doesn’t differentiate between G0 and G1 moves, so they happen at the same speed, and G0 doesn’t automatically turn off the beam, which, again, both GRBL and Smoothieware do.
GRBL with an Arduino Nano is ok for cutting and simple engraving. If you’re trying to engrave photos, it will be limited by the speed it can process GCode (roughly 250 GCode instructions per second).
BUT WITH UNO IS OK RIGHT? i write wrong xD sry. With uno i can work normaly right? and one more question… how can i make a smoothing swing while scann? like in DSP, is there a way?
Yes, it’s quite functional and works very well, it’s just limited as to how fast it can process commands, so any job that sends many commands in a very short period of time (more than about 250 per second) will overwhelm the processor and it will not keep up.
If I understand your question, you’d enable ‘overscan’ in the fill settings.
