What controls homing

Have replaced board behind extruder, motherboard and updated software. Print head still hits right post when trying to home.

Older devices (Ender 3, Ender 3 pro) had a few microswithes that were activated when homing… (so printer knew position of the printerhead)…

Exactly test the microswitch, the cables and the support holder of the microswitch.

Did you put all connectors in the right sockets? Hitting the right post… should it move to the left for HOME?

Connectors in the right sockets. The SE has a board behind the extruder holding the limit switch, I have replaced that and the motherboard. If I turn off the machine before each print and manually home to the left it will usually print normally. Printer won’t auto level, moves to the right stop and tries to level on the right edge hitting the stop.
