Omron inductive probe accuracy

Hi All,

I am having some challenges with my Switchwire's Omron inductive probe / mesh. Now, I have to confess I do not know if this probe is an OEM component or a ripoff part but it looks genuine (has a black wiring outer sheeth if that helps).

Now, I am getting some inconsistent results when probing and the results point to it possibly being elsewhere and not just the probe.

This testing was run with a cold printer (23 deg c).
If I home the printer i can then do a probe accuracy test and it will give a consistant result i.e 8-9 out of 10 are the same.
If I run a mesh then the probe will have challenges with the first series of 3 per probe point on a lot of the 6x6 mesh and then come back with a successful second set of 3 on retry. This is on two different beds (i.e I used the I3 MK3 as well as a new PEI spring steel bed)
From the looks and consistency it looks as much like a motion problem (i.e on each move it is having a challenge with that probe point) as a probe issue.

To diagnose, I increaded the stepper current on the base config file from LDO from a run current of 0.5 to 0.7 to see if that maybe the problem on X and Z. I also tightened the belts.

This is my last set of tests prior to heading to a test print so wanted to see if there is a fix / somewhere to look.
Frame is possibly LDO - looking at the way it was anodized after being tapped.
Steppers are LDO
Rails are LDO
Belts are gates
Bed is PRUSA MK52 with MK3 top and I also tested a different PEI bed.
Motion prints are the originals I received when purchasing this second hand in parts - dont look too bad. Bearings all feel ok / turn freely.

Has anyone else come across this issue on the Switchwire?

cheers
