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?
The datasheet of the power supply:

Check the wiring to the steppers. I can’t see what the stepper pulley is doing, but it sounds like it is not working right because it is mis-wired.August 13, 2019 at 11:02 am #109522
were you able to resolve the issue?August 14, 2019 at 5:03 am #109594
It’s a clone. They all seem to have issues. I want to say it’s a stepper pinout issue, but I don’t have one to play with. I’m thinking they got the stepper pins in the wrong order.
Also, sitting electronics on plastic bags is really a bad idea, esd is a cold hearted bitch.
