# Auto level points

I notice that auto level was screwing my first layer in corner 1 and 3 which coincides with prop point 1&3. I turned off auto level and my bed was with in .1 mm across x and .2 ish mm across y. So I looked at the probing points results you can see it below. I also found out that 3 out of the 4 points are not good in my opinion. Points 1,3 & 4 are too far in y direction as you see in the picture. I would like change the Y value for points 1&4 to 156.000. Point 3 I would like to change the y value to -10 if possible. it seem that my bed is not squared with chase. I would like all four point to be on the inside corner of glassl like prop point 2 (see picture). I know that i need to change
#define LEFT_PROBE_BED_POSITION (-3 + 0)
#define RIGHT_PROBE_BED_POSITION 161
#define FRONT_PROBE_BED_POSITION (-7 + 0)
#define BACK_PROBE_BED_POSITION 161
First I don’t want to lose my current configuration.
Does the Bed Height vs. Bed Topology look right look correct?
How can I compile a new firmware when I can’t download the software development from lulzbot?
How can I fix my bed to get it squared?
Can I change the position of one prop point without effecting the others?

Prop point 1

Prop point 2

prop point 3

prop point 4
