I got one of the first productions of the Omerod. This printer has been bought but it has never printed anything in all these years. I asked the owner if i could try to make it work, and it has been a bumpy road so far!
So i hope maby some of the experienced users can help me fix my problem!
The problem is when i try to home the z axis. This is measured by the Z probe and i have a very old one with 3 connectors. Before i start i type M558 P1(to activate probe) First i checked if the z probe was working correctly by taking measurements when it was at 40mm from the bed and the result was around 60. Then i moved the axis towards the bed and the value changed along the way untill i reached 987 at 0.7mm from the bed. I send in the G92 Z0 command and after that i set the the G31 Z1.4 P719 ( i tried different values).
The nozzle goes the the Z0 as it should do, but when i want to start the print after that it always crashes into the bed. When i restart my Ormerod and i want to home my Z-axis it crashes and the stepper keeps running. So it seems the calibration has no effect.
This is my Config file:
