I am strugglling with a project. I'm making my first CNC Machine using Arduino, CNC Shield, GRBL 0.9J and Universal Gcode Sender 2.6.
My problems are:
My homing cycle doesn't work;
When i the "return to zero" comand, the steppers go crazy and make loud noises
When i send Gcodes, the steppers only make a very weird noise and doesn't move.
When i jog, everything goes normal, but from the tutorials i've seen, my motors are working way too slow.
I have already asked for help on GitHub but i don't get any answer, and i don't know where else should i ask for guidance
I'm using Hard Limits and they work perfectly
My power supply is 12V / 20V. I've already tried a different one (24V / 15V) and i don't see any difference.
I replaced the Arduino Board, still nothing.
I used another CNC Shield, still nothing.
I tried Both GRBL 0.9 and 1.1 with Universal Gcode sender 2.0.6 and 1.0.9
