I have a Anet a8 and have installed a BLTouch auto leveling probe on it (-50mm x axis and 0 to the Y axis from the nozzle). Everything works regarding the probe.
I am having trouble understanding and setting up the boundries of the probe so it can probe all 9 points of my 220 X 220 bed..
When mesuring where the probe ends in relation to my bed at the end stops they are:
Probe
50mm off the bed on the left front
20mm inside the bed on the right front
on the edge of the bed at both front and rear of the bed.
I am fiddling with Marlin 1.1.8 to have reasonably close but no luck.
Looking everywhere to find a simple mathamatical equation or better yet a simple explanation to what values I need to input into Marlin.
