I am running an SKR e3 Mini v1.2 on my Ender 3 pro.
I have compiled Marlin 2.0.1 and most functions are working correctly.

I am trying to set the Min Probe edge to have a more symmetrical probing grid.
However, it seems that the below function is DOUBLING the value for some reason.

My probe offset is X=-45/Y=-10.

When I have MIN_PROBE_EDGE_LEFT set to 15, the first probing point occurs at X=75 (15x2+45).
This multiplication occurs for only for the MIN_PROBE_EDGE LEFT and RIGHT values.
FRONT and BACK work perfectly.

I can't seem to get to the bottom of this.

#if PROBE_SELECTED && !IS_KINEMATIC
  #define MIN_PROBE_EDGE_LEFT 15
  #define MIN_PROBE_EDGE_RIGHT 0
  #define MIN_PROBE_EDGE_FRONT 10
  #define MIN_PROBE_EDGE_BACK 10

Give bugfix-2.0.x a try. That should have been fixed in #16367.

Thanks from saving me from looking this up. I thought that fix was already in 2.0.1, but I guess it came later. There's another open issue that looks like it as well.

I am assuming this issue is already fixed, unless someone confirms they have problems using the latest state of bugfix-2.0.x.

Sorry, didn’t get any notifications that there were posts.
I did attach a zip when I posted that included my configuration.h and configuration_adv.h. Don’t know what happened to it.

Seems like the issue was resolved in the 2.0.x bugfix.
2.0.1 does not have the fix. I made the changes manually and it works s expected now.
