Should we add a tag for 'laser' for those of us who are attaching laser cutters/burners to 3D printers to turn them into 3D CNC. Or is this drifting too far off topic from "3d printing"?
A good question. I'm currently using insights I obtained from mucking about with a 3D printer with Arduino Mega 2560 and RAMPS 1.4 to dive into retrofitting an elderly CNC router (but, as a router, still, not as a printer) with a new control system (presently thinking and have on order Arduino Uno R3 and Arduino CNC shield R3, we'll see how implementation goes on those) and was wondering if I could ask questions here that would overlap, or not, as I don't think there's a CNC/subtractive community similar to this 3DP/additive one in the ecosystem yet.
I actually started out thinking I could just use the same controller setup (there's plenty of stepper driver slots available, and going "dual-purpose" cut and print is potentially interesting) but it seems the official GRBL fork is not 2560 compatible, though there is a fork to try and make it so - it seemed more of a sure bet to stick with the "official" fork and the common hardware.
Likewise I've seen a bit of chatter about making Marlin switch-hit CNC/3DP, but I get the impression it's not all there yet, and I'm more interested in immediately usable based on current/past efforts than trying to develop new functionality my dang self.
The tag laser has been created. Would you like to provide usage guidance and edit the tag summary and body?
So far I have found one question which is laser related, Laser Engraver with Smoothie, RAMPS 1.4 or AWC708C?. Seeing as you posted this question, did you have any other questions in mind that required that tag? If so, would you mind tagging them as such?
