Do you need more stepper motors, or more axes? If the former, you can just pair one output to multiple stepper drivers; this is common for gantry...
Hi Bob, AFAIK, GRBL only uses the serial TX and RX pins for comms. GRBL itself doesn't use any Arduino code, and isn't set up to have the USB...
Hi jbell, Not sure if you're aware exactly of what GRBL does, so here goes. Just so you know, GRBL is a fairly low-level program that sends the...
Perhaps the grbl-builds repo? Don't know if there are any appropriate build for a 2560 ...
... that, and I'm sure much of the code quality is ... lacking. I've tried to make minimal changes (to edge), and to make it a bit more clear...
My statement came with some caveats. pcb2gcode is aimed at using a cutting head (a milling machine) to cut away where you don't want copper,...
Look into a program called pcb2gcode. It's more for using a router to cut out traces, BUT, you could use your pen plotter with negative...
So ... if I were to do some merging, would it be best to do it against 'edge' or 'master'? Edit: More to the point, will you accept pull requests...
What about this part? if (st.set_rpm == true) { OCR_REGISTER = st.exec_segment->spindle_speed_pwm; st.set_rpm = false; return; // I...
I'm sorry to hear that. =( I hope things are better soon. I did look briefly at the GRBL source, and the changes made by Alpharesearch, here....
Three questions, actually: Does the current "edge" branch of GRBL support modulated spindle speeds based on acceleration, as mentioned in GRBL...
