Just did it a sec ago,

Seems to work quiet well, I use a tower pro SG90 btw,

>>>M48 n 15 x 50 y 50 e
SENDING:M48 n 15 x 50 y 50 e
M48 Z-Probe Repeatability test. Version 1.50
Mean: 2.885400
Standard Deviation: 0.008681
echo:endstops hit: Z:2.88

When doing a M48 for the first time it did the probing at x100 y100. The play was then (Standard Deviation: 0.018029)




The e command should make it retract and extend right? Well that doesnt seem to do anything here tho.
