Independently leveled Z axis Issue

@martin7404 your 4 point height map suggests your bed is quite level.
Martin is just bragging!
I think my issue might be the magnetic sheet cracking causing a ridge making it not flat in the back left corner. I'm going to take off the magnet tonight and give it a go with just glass on on aluminum. I just cant be down too long because I'm behind on parts.... I need to build more printers.
My bed has ever been as flat as I would have liked it. I may take a skim cut off the top. Has anyone had good luck attaching a silicon heater back on after its been removed?

I am not bragging, just chime in to share that with faulty board/drivers I got wrong compensation in triple Z setup, the rest is too much I agree.
My bed is within a few thousands without the magnetic mat and the mat is off with 0.1 mm -

I know, I'm just giving you a hard time.

MY new board is here tomorrow so I will be able to go back to original setup.
P.S , Until now I was using prusa slicer profiles of GUI for left and right tools that activates only needed tool and today started calibration prints with dual material, and as far both tools are activated in the beginning , there is difference and it is that during print the standby tool cariage is not moving at least visualy -
@martin7404 That's strange, not sure how that would make a difference.

@fcwilt My bed is definitely bent in the back corner. I'm not sure if this is entirely the issue because it gives a deviation of .1mm but its definitely more than that. I did not consider this as I didn't have any issue for the first six months of use. I'll take it into work and have them make a skim cut to see if this helps.

Do you know why the mesh is not centered but in the negative?

That's usually because you're not setting Z0 with G30 before doing the mesh.
-
@Phaedrux It homes first which has a G30 at the end so I thought that would apply but Ill try a G30 right after the G28 and before the G29.
-
I'd have to see exactly what gcode is happening in order and what your probe is etc. Normally the Z0 point would be green and the differences above or below. But it's all below, so that means where ever Z0 was set is above the surface of where it thinks the bed is when the mesh was created.
The total deviation is quite small though so the heightmap can appear exaggerated. There's also only 4 points, so it could very well be obscuring the Z0 position because it's very far away from the probed points of the mesh. I think a higher resolution height map would tell a more accurate story.

@3DPrintingWorld Today while comisioning my new coreXY and as far my plate was givin 0.15 mm deviation on the G29, I played a little with G32

@fcwilt I will answer for me. No, my issue was never resolved.

Well I'm sorry to hear that but I have no idea what we are talking about.
