Z axis Not Moving for Mesh Compensation
-
Hello everyone!
I have a highly modified Lulzbot Workhorse (2x Belt Z). The MB is a Duet 3 mini 5 running 3.5.0. Other than the issue at hand, the printer functions perfectly and is proving to be a reliable workhorse, thanks to the help of this group. That said, My Z axis stepper motors do not move for mesh compensation during a print, at all. I have read through all the documentation as well as several posts in an attempt to solve the issue on my own. I just cant seem to figure it out. All things point back to it working properly but there is no Z axis movement at all. I will include everything pertinent to this dilemma and more than likely one of you great people will come in and make me look like a schmuck as usual. But that's ok. I can handle it and I'm getting better, hehe

Hotend Photo:
That BLTouch is not crooked as it appears in the photo. It is very perpendicular to the bed/toolhead as it should be.I have ran it with the G29 in both my startup .gcode as well as in the homeall. result is the same, or lack thereof. I know this is a common issue with common fixes. I may have missed/overlooked something so be patient and thorough. Thank you in advance for talking the time
. If there is any additional info that is needed, please do not hesitate to ask. Also, If you see anything else that can be improved upon or tweaked during your investigation, I would greatly appreciate any feedback you would be willing to provide.

G29 ; Bed Mesh

G32 ; auto-bed level/tram
G28 Z ; Home ZYou're doing a mesh before leveling the z axis and then homing z. This seems like a backwards order.

M98 P"home'z.g" ; home z axis
What is this macro? Please post it. Is it the same as homez.g?
-
@Phaedrux I have no idea what that is or how it got there. I certainly didn't write it. Here they both are. The "home'z.g" has to be an accidental duplicate and may need to go. Z axis has two steppers but does it need both of those files? I think one needs to go but which one?

You're going to have to clean up your files and determine which Z axis homing routine you actually need to use.
Then in your slicer start gcode, change it up to start with homing z, then tramming (which should also home z at the end to re-establish the Z0 point in case the change in tilt has changed it), and then do your mesh.
-
@Phaedrux I've already fixed the startup gcode. How do I determine which z axis homing routine I actually need to keep? Is that something you could provide a bit of assistance with? I can read code but not likely as good as you can. I would be inclined to remove the duplicate and deal with the fallout if necessary, (fix the remaining one) but that may not be the best solution.

@SonnyD1 said in Z axis Not Moving for Mesh Compensation:

Homez.g is using the probe to home Z.
Home'z.g is using an endstop to home Z.
Which is the correct way to home your printer?
-
@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 mesh If 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!
