Z axis Not Moving for Mesh Compensation
-
@Phaedrux Ah ok. I do have a high end z endstop in addition to the BLTouch. Would the home'z.g be the file for that one?
-
In that case you should definitely remove
M98 P"home'z.g" ; home z axis
from the end of your homeall.g as it will be homing to the endstop at the end and resetting the Z0 position found by the probe.
You can keep home'z.g around for when you want to home to Z max, but keep in mind that the Z position set by it may not be accurate to what your probe has determined z0 to be.
-
@Phaedrux Done! But is that the cause or does it effect my an axis not moving to compensate for mesh?
-
Please share your current config.g homeall.g, homez.g start.g mesh.g bed.g and slicer start gcode. Also a M122 report taken during a print.
-
@Phaedrux I don't have a mesh.g. Here is the rest of it. Is the lack of a mesh.g the issue?

@SonnyD1 said in Z axis Not Moving for Mesh Compensation:
Is the lack of a mesh.g the issue?
No. Mesh.g is an optional macro that you can use if you want to define exactly what happens when G29 is sent.

@SonnyD1 said in Z axis Not Moving for Mesh Compensation:
M558 K0 P9 C"121.io0.in" H5 F600:120 T6000
You're using K0 in the probe definition. If you do this, you must consistently use K0 in all other probe related commands. If you only have a single probe, just omit the K0 entirely and the firmware will assume you only have a single probe. This may be a part of your issue.
@SonnyD1 said in Z axis Not Moving for Mesh Compensation:
M376 H10
You have a mesh taper set as well. This will reduce the amount of z adjustment and may also be part of why it seems like nothing is happening. Try commenting this out for the time being.@SonnyD1 said in Z axis Not Moving for Mesh Compensation:
bed compensation in use: none
According to that M122 report, the mesh is not active at the time it was gathered, but your slicer start gcode should have an active mesh after your G29 command is executed and the mesh is performed. Was it gathered during the print?
G28 ; Home all G32 ; auto-bed level/tram G32 ; auto-bed level/tram G28 Z ; Home Z G29 ; Bed meshIf you send those commands in the console and then move the print head around in XY do you see the Z motor turning? It can help to attach a small piece of tape so you can see very slight movements.
-
@Phaedrux I removed the K0 from the M558 cmd and commented out the M376 for now. That M122 was taken during a print as was the one above. The one above showed bed compensation in use as active.
@SonnyD1 said in Z axis Not Moving for Mesh Compensation:bed compensation in use: mesh, height map offset -0.222
Its weird that this one did not. I'm gonna run a M122 on a fresh print with those changes on a fresh slice.
New M122 results:

One of the best ways to test if mesh compensation is working as expected is to slice a full size bed level test print and then print it twice. Once with compensation active, and again without. It should be pretty obvious if it's effective. Here is an STL that is fast to print.

@Phaedrux That's exactly what I was thinking. I need some exaggeration. Thanks for the help. I'll get back with ya!
