Mesh bed leveling not working
-
I've tried with the same results running both g29 and g32, neither of my printers save a mesh.g file, not sure why
There is a fair bit of play in the gantry, belts are tight

Because it's a file you create akin to bed.g.
G32 calls bed.g
G29 would call mesh.g if it existed.@pats-prints said in Mesh bed leveling not working:

If you move the X axis back and forth can you visually tell that it's tilting the probe/nozzle back and forth as well?
-
@phaedrux no, moved it back and forth rapidly no issues, hotend doesn't seem to move at all.
My last ditch effort I just tried was moving my ender's pei sheet and calibrating on that. Same problem.
A thought just crossed my mind that on the cheapo anet they used two different lead screws? Causing this issue no matter what I do to fix it
-
Well the image of your heightmap is tell tale backlash. It's higher in one direction and lower in the other. Until you identify and eliminate that backlash, it will persist.
-
@phaedrux I'll see if the prusa X helps, otherwise this printer is going in the trash
-
What's a prusa X?
-
I see your probe‘s offset is 15mm on Y.
If your axis is slightly tilted it’s more pronounced for the probe and the mesh is not usable. -
@phaedrux meant the prusa bear x upgrade
-
@argo the probe is offset x 0 y -50, it has happened across multiple sensors and bed types the nozzle slopes to be in the air on the low end of the x and scrapes the bed on the higher end of the x
I guess I should also mention I started with 2.0 firmware and recently switched to 3.3 to see if it would help
-
The bear parts didn't fit but I tried 2 LMU88 bearings on each side for the x carriage and had horrible binding. Went back to the stock long bearing- and still the exact same issue. the bed looks fine on the height map viewer.
I think I'm just going to buy some corexy machine and throw the anet in the trash
thanks for your input

Sometimes that is the best thing to do.
I had three deltas and decided I didn't like them - gave two away, trashed the third.
