Description

When using latest compiled firmware: https://github.com/bigtreetech/BIGTREETECH-SKR-mini-E3/blob/master/firmware/V1.2/firmware-bltouch-for-z-homing.bin

and using a v1.2 board the probe travels too far to the right when auto leveling.

Steps to reproduce

  1. Download latest compiled firmware: https://github.com/bigtreetech/BIGTREETECH-SKR-mini-E3/blob/master/firmware/V1.2/firmware-bltouch-for-z-homing.bin
  2. Name properly and flash Ender
  3. Reset settings, M502 then M500
  4. Perform autolevel
  5. BLTouch centers correctly, lowers, probe finds surface correctly, retracts, and repeats.
  6. Bed leveling commences
  7. BLTouch is moved to front 1/3 of bed, 1st probe is successful
  8. Probe is moved right almost to end of the bed, probe is successful. 9 Probe tries to move to the right but hits end of travel is and physically stopped.

Expected behavior Probing should start more towards left of the bed, it should do X number of touches and then proceed to the next row of touches.

Actual behavior Probing sequence after centering starts more towards left center of the bed and runs past the normal bed size when moving to the right after the 2nd probe.

Additional Information

Using the provided firmware so no config file.
