Importance of precise probe offset values?

General Discussion

As the offset is static, my approach is:

  1. Put some layers of electrical insulation tape on the bed
  2. Slowly drive the nozzle into the tape until it leaves a visible dent (doesn’t need much)
  3. Issue a GET_POSITION and note the coordinates
  4. Move the tip of the probe as precisely as possible over the dent (for BLTouch I do this with extended probe tip)
  5. Issue a GET_POSITION and note the coordinates
  6. Calculate #5 minus #3
