Hi everyone
I finished building my MPCNC Bought the Mini Rambo 1.3 and LCD on AMAZON since V1 was out of stock a few weeks back
So I connect everything with wires bought from V1. flashed the board with the marlin version from V1
And to my surprise I have a grinding sound on the Z axis. X and Y work well with the same settings. I tried everything I read about checking the wires , changing to a new motor. I swapped the wiring and motor from the X axis with no change. Still grinds on the Z even when the motor runs free.
It all points to the board…. or some mystery setting in Marlin (I’m stuck here)
Anybody have Ideas
I joined my Marlin files as attachements and pics of my motor and LCD (which turn’s on but nothing appears on it)
Need help
Pete
