V2.4 TAP Z drive issue

[ManiekJG]

Guys please help. I have run a probe accuracy python script after installing TAP. and looks like I have a big issue with two corners? The one on 275, 275 is higher than others even though the cript did run QGL. The corner at 25,25 is biggest mistery. I have tried retightening all loop belts, retightened Z belts, retightened all grub screws, retightened gantry bolts (I use IGUS spherical bearing), made sure the belt clamps are tight. I did have some issues with auto Z etc before TAP as well but thought it might have been my old probe. Any other things I can check? Will it be fine if I will run it like this? Steppers are at 32 microsteps and 0.8A. I have also run the 100 samples of Probe accuracy like 5 times for it to set.

Well, you are probing to compensate for deviation so I would say it should be fine. Are you having printing issues?

Actually I can't seem to make my first layer to work. Once the Z offset is like -0.86 where I can feel resistance on paper. After saving the value to config and restarting klipper during print it's so way off that nothing sticks to the bed. After re running the calibration tool the new value is -0.78 and same situation. I'm getting a bit frustrated

Start looking at things that might not be as obvious like marital hardness, color or material TAP was printed in.
Maybe you need to re-rack the Gantry?
