G31 translated off bed

smoothie-forum
(Feith27_SW) #1

Hello all, I am running a large Delta printer with an Azteeg X5 Mini V3 board from a Windows 10 Computer. Whenever I issue the grid probe command (G31) my printer attempts to probe points that are off of the bed at the start of the routine, then skips other parts of the bed near the end of the routine, almost as if the grid has somehow been translated backwards on my bed. Any ideas on what is causing this issue and possible fixes would be much appreciated.
