Describe your issue:

I have been using my printer today and I adjusted baby stepping then SAVE_CONFIG. Now, my printer will not complete a G28 Home.

When I command G28, the printer will move the Z axis down 10mm, then home X and Y, but will not drive the Z axis to the BLTOUCH probe.

I can force_move the Z axis up and down.

Any ideas why G28 will not drive the Z axis to the BLTOUCH probe?

Is it a genuine BLtouch or some clone?

I have been using a genuine BLtouch probe on this printer with Klipper for about a year.

The problem occurred after baby stepping z-offset then issuing a SAVE_CONFIG command.

I found the BLtouch connector was not seated. I reconnected the connector and now the printer will perform a G28 HOME.

Thank you.
