@phaedrux It seems to be working at this moment. I printed the STL that you sent over and seems to be behaving, although I'm still seeing very very slight variations in layer width across the bed, it's good enough for the time being to move forward and work on pinpointing some of these issues in getting my Z=0 datum set correctly.

@fcwilt

This is very convenient, thank you for the tip.

I had a few succesful print since I made the Z-offset correctly.

@Stephen6309 said in z probe offest:

@way2lo2 Not sure, but I do know the firmware won't go below Z0, if you have your M208 set Z minimum to 0.

That's right. So on the first layer the most you can baby step down by is the first layer height.

For best results the probe trigger height must be accurate. Set it at the same point you use for homing. And use that same point for setting Z0 before generating a heightmap or after doing tilt correction.

If you do need to baby step down consistently you can use the amount used to modify the G31 trigger height to make it permanent.

Setting the M208 Z minima to -0.5 would let you go a bit lower, but use that with caution.

Thank you! It will be great for beginners as well.
