"Home Towers" only resets 2 of 3 towers... sometimes.

[EngPhysGuy]

My Orion has developed an intermittent problem.

Both with manual and software input the "home towers" command will intermittently only home 2 of the 3 towers.

The front right tower will sometimes move up (homing) with the other two towers but will stop homing once the others have homed.

This is intermittent .... showtimes all 3 towers home, sometimes not.

Any thoughts.

Make sure the endstop wires are isolated from all other wires on the printer, they could be introducing enough noise on the wire to make the printer think the endstop has been triggered prematurely.
