Homing Off-Center for v2.0.1 #1814

Closed iamBenCurtis closed 2 years ago

iamBenCurtis commented 2 years ago

Description

Ender 3v2 with BLTouch is homing to a position that is pretty close to center for the X axis but very front of bed (close to front of printer) for the Y axis. Using precompiled build E3V2-UBL-BLTouch-15x15-v4.2.2-v2.0.1

Steps to Reproduce

  1. Write down original values for things like probe offset, z offset, filament load and unload amounts etc., shut down and unhook OctoPrint
  2. Flash
  3. Re-enter values from step 1
  4. Home
  5. Printer homes off center of bed
  6. Frustratedly check the collective knowledge of the internet
  7. Turn off printer, back on, Reset to default, Restore Settings, Store Settings
  8. Double check settings from step 1 again
  9. Home
  10. Printer still homing off center

Expected behavior: Printer homes to center of build plate

Actual behavior: Printer homes to center of X and 2/3rds to the front of Y

@tititopher68-dev I am ashamed to admit that this entire issue may have been user error. I believe that I caused it to appear off by entering in my probe offsets for Y as positive when it should have been negative. the 35.5 doubled effectively and caused everything to be off by 71mm. I didn't figure that our until I flashed with version from #1694 and it still happened. Then I questioned my own writing abilities. Thank you for your time and effort in all that you do!
