Calculating your Z-Index Offset

Just a quick post to talk briefly about setting your z-index offset.  It is fairly straight forward as long as you get the right positive and negatives figured out.  I have made a handy worksheet to assist with it.

The worksheet can be found:


All you have to do is:

  • Download and print the document, one page full size
  • Run a G28 command on your printer.
  • Make a mark that corresponds to your sensor
  • In your config enter the appropriate values
    • Blue is positive
    • Red is Negative
    • X offset is left right
    • Y Offset is forwards and Back
