How to specify exact probing points in config.g

[deonholt]

@PCR
G31 P500 X-45 Y-12.20 Z2.965

[PCR]

then try

M557 X0:173 Y20:219 P3

@Veti
This is my offset:
G31 P500 X-45 Y-12.20 Z2.965

So, I need to know how to enter a single probe position so that I can see where it probes. I want to use X110 Y110 as a test.

@PCR said in How to specify exact probing points in config.g:

M557 X0:173 Y20:219 P3

dont forget the y
so

M557 X0:173 Y0:205 P3

[PCR]

@deonholt

@Veti is right try

M557 X0:173 Y0:219 P3

[Veti]

@PCR

his bed is 218 so 218-12.2=205

@PCR
Thanks, will quickly try it.

Update: It probed 6 points. It started off promising but stopped after 6 with these errors:
G32
Warning: Skipping grid point (0.0, 219.0) because Z probe cannot reach it
Warning: Skipping grid point (86.5, 219.0) because Z probe cannot reach it
Warning: Skipping grid point (173.0, 219.0) because Z probe cannot reach it
6 points probed, min error -0.011, max error 0.049, mean 0.013, deviation 0.022
