SKR v1.3 Mega X Problem

[brosskgm]

Tried email address listed, but it bounces. support@bigtree-tech.com, ERROR CODE :550 - Mailbox unavailable or access denied.

1st using the Marlin 2.0bug fix. Now have Marlin 2.1.2.4 on the Mega X.

All the endstops with dual Z are all on x,y,z Min pins and the dual Z is on X_Max pin and it works fine. But have been wanting to install BL Toouch, and it wants Z_Min pin.

Haven't had any luck finding instruction to change the pin to Z_Max,

Many problems trying to get them to work on X,Y,Z Max pins and dual on X_Min. Never homes correctly or many times only moves a short amount and stops.

Does anyone by chance have the Marlin config files for the Anycubic Mega S or Mega X that will work on the SKR v1.3 using the Max Pins?

Thanks
