Strange BLTouch issue

Hey guys, so i printed out some new X-Axis holders and now there is much tighter fit as before and i measured 0.726 and 0.658 on both sides, so far its much better then before but still not perfect. But i did a few test prints and they came out with a perfect first layer. And i dont have any more issues with the rotation of my X-Axis. Thank you for all of your help to find out what was causing that issue

For my X-Axis i am using a modified version of the Prusa printable parts. But i noticed that my left side is broken, where the smooth rods come into the plastic part.

yep i followed that tutorial: https://duet3d.dozuki.com/Wiki/Test_and_calibrate_the_Z_probe
and on the left side its 1.294 and on the right side its 0.935

i think this is not good, becuase the offset should be the same on every side right?

so, i rebuild my entire extrudersetup and i still have that issue.

hm, the hotend shoud be fine i didnt notice any sagging there. I will now rebuild my old stock hotend (cr-10) and see if its causing the same problem. If not, the bracket that i am using to hold my Titan Aero is very bad. I will give an update in a few hours.

i was just wondering about the 0.000, but still i have that strange issue that my map is kinda flipped around. The right side is too far up and the left side is too far down... its doing the opposite of what the mesh is giving out.

So i think its on, but i am not sure why the offset is 0
