Hello everybody
My project is a large 3D printer. I understand the CNC zone is about CNC (logic ), but the electronics and motors are very similar between my 3D printer and a CNC (I need powerful motors).
ELECTRONICS
ARDUINO Mega 2560 + RAMPS 1.4 + power supply 12V
DM 5042 external driver + Power supply 36V + NEMA 23 stepper motor
SOFTWARE
Repetier Host to communicate with the Ramps
ARDUINO to upload the firmware (Marlin)
TROUBLE
the motor NEMA 23 reacts when the ARDUINO board receives a command … but not as expected : indeed, it makes a little noise like a "zzzzzzzzzzzzzzzzzzz" instead of moving normally (in other words, the axis of the motor does not turn on itself).
I checked several times the connections, components …etc. It seems to be fine.
I do not understand where the trouble comes from.
Anyone can help me ?
Thank you very much in advance
best regards
Fab
