anyways i hooked everything up , flashed the firmware but every time i want to test the cnc nothing happens well here is the whole log when i try to manually move any axis:

so i have no clue why there is always those 2 unknown commands,
i already flashed different types of firmwares but nothing helps also the lcd and the board looks fine , anyone have a clue what i need to do?

There’s an online reference for the commands that Marlin supports here which I find invaluable in understanding what the GCode is trying to do.

M80/M81 turn the power supply on/off. This is for 3D printers that use a switchable ATX-style power supply. Since this feature is disabled in @vicious1’s firmware it returns the “unknown command” message. You can safely ignore this error.

M221 is attempting to set the flow percentage for an extruder. Once again, safe to ignore if you don’t have an extruder.

It’s clear that Repetier is connecting to the control board, and its reporting you’re running version 427 of the V1 Engineering firmware.

Are you supplying electricity to the motor connections on the board? You don’t say which controller you’re using but most have a power connection for logic and another for the motors. Some boards will run the logic from power supplied by the USB connection, but you need to add the power supply connection in order for the motors to move.

Those errors can safely be ignored.

New firmware has moved to MarlinBuilder releases and should be something like 508.

All right I have the Rambo, and looked again at the connection plan and you were right, I thought the power supply, connected to the b terminal was enough, I just didn’t recognized the c terminal needs another one, so Im going to test if that was the only problem, thanks very much guys

erikthegreat · December 12, 2020, 11:12am

Hell yeah, Problem solved, I thank you guys very freackin much

Im having the same problem now, it was working fine and when i hit print one more time, i started getting the error. I can manually move the router, it triggers it on but it doesn’t move.
