I have finished the mechanical part of my Mpcnc.
(except the belts)
Now I flashed my MiniRambo (China clone…) with the latest firmware for this board that I found here with Arduino IDE 1.9
I attached the motors to the board (only one X and Y, no parallel’ed yet).
The problem is that when I try to move in repetier Host, the movement is very short (not 10mm, if I chose 10mm) and the board seems to restart after the command. The voltage goes down as you see in the Video.
Is my board a problem?
I use a professional 450W - 12V power supply, baudrate etc. was checked to match, I tried different baudrates and changed it in the firmware… nothing helps.
What can you think of?
