Probe offset Buddy

A tool to help determine Z probe offset after installing a bl touch or a new fan duct. Has raised hole to fit your tip into (giggity). The horizontal line to the right of the hole begins at center of hole, offset by 1 cm to the right.

Surrounding circle is just there to center print, the layer height is small enough that it won't print. The hole is offset from print center (-55 mm, -18 mm). You can offset this print, based on your calculated probe offset and print it again to test your offset. Autohome after printing, and your deployed probe should be able to fit in the hole.

1. Print in the center of your bed, do not remove from bed.
2. Deploy Probe
3. Adjust your print head so probe tip fits neatly into the raised hole
4. Retract probe
5. Heat nozzle and lower until it is just touching the print and melts a small point in the print.
6. Adjust in Y direction to melt a line to the edge of the print
7. Measure length of melted line to determine Y offset
