A Cura plugin that adds a Z Offset setting

ZOffsetPlugin

This plugin adds a setting named "Z Offset" to the Build Plate Adhesion settings in the Custom print setup of Cura. Entering a positive value to in field will result in the head printing everything that amount further away from the build plate.

The Z Offset setting can be found in the Custom print setup by using the Search field on top of the settings. If you want to make the setting permanently visible in the sidebar, right click and select "Keep this setting visible".

The plugin adjusts the first move on the Z axis in the first layer by adding the Z offset value, and then instructs the printer to consider this the original first layer height. For example, layer 1 of a print with an Initial Layer Height of 0.25, and a Z Offset value of 0.05 may look like this:

...
;LAYER:0
M107
G0 F4320 X135.625 Y125.625 Z0.3 ;adjusted by z offset
G92 Z0.25 ;consider this the original z before offset
;TYPE:WALL-INNER
...

Unfortunately this technique does not work for Ultimaker printers with firmware 5.2 or newer due to a bug in the firmware for those models. For those printers, the whole gcode file is processed to offset all moves that include a Z coordinate. This takes longer, but is otherwise functionally equivalent. Since some other printers also misbehave after using the G92 command, this alternative "extensive processing" method can now be selected as an additional setting for all printers.

With either method, the Z Offset can never be lower than the negative of the Initial Layer Height. That would result in a negative Z value, which at best would be caught by the firmware and result in an error during printing, and at worst would lead to the nozzle being pushed into the build plate, damaging the printer. So with an Initial Layer Height of 0.25, the Z Offset is limited to be -0.25 or higher.

cura-zoffsetplugin's Issues

Z-Offset for Start G-Code possible?

Is it possible to change the Z Value in the start g-code with the plugin?

I want to quick change the Printbed. Normally i got a glass bed and want to add a 1.1mm thick textured sheet. All works fine but the purge line created with the start g-code.

Kind regards

[Feature request] Reset to original on ;TYPE:SKIN (bottom skin)

hi,

Hi I'd like to request a feature in which the ZOffset on apply for the first layer wall(INNER/OUTER) and revert back to original once it is on 1st layer TYPE:SKIN. My use case it to improve the bed adhesion of initial thin lines/wall by squishing it a bit while preventing the SKIN in having ridges due to the offset.
Regards,

Jeff

# 1st layer
G0 F6000 X62.827 Y75.333 Z0.18 ;adjusted by z offset
G92 Z0.2 ;consider this the original z before offset
;TYPE:SKIRT
;TYPE:WALL-INNER
;TYPE:WALL-OUTER
;TYPE:SKIN
G0 Z0.2 ; reset to original for bottom skin

Does this still work?

I'm not seeing a Z Offset setting anywhere.

• With Cura 4.0 or 4.3

does not work anymore on latest firmware (5.2) on um3

ZOffset option not available in per model settings

Plugin version: 3.6.0
Cura version: 5.3.1

Option is available in "Print Settings":

But not in "Per Model Settings":

It would be very useful to have z-offset accessible in "Per Model Settings" when calibrating the z-offset for the first layer.

There should not be a minimum value

Currently, we have

"minimum_value": "-layer_height_0",

For accurate bed leveling I wan to use a credit card, which has a 0,8mm height. I need to apply a negative offset bigger than my layer height in order to get to it. Maybe using a minimum value warning instead of a hard limit?

PS: Thanks for the plugin, it's helping me a lot with calibration.

3.5.6 Problem

in Version 3.5.6. the Plugin is not adding any Z-Offset to the G-code

Not showing in 5.4

It isn't showing up in 5.4.0 I have installed/Uninstalled multiple times from within cura and from the git file and still nothing.

Increase print strength by applying Z-offset alternately to adjacent walls and/or infill

Add an option tick box that applies the Z-Offset value only to every other adjacent line. This will allow a line to be offset in Z compared to each line on either side of it. This will interlock each adjacent layer by the Z-offset amount which will increase layer strength by effectively spreading layer separation forces over a much larger layer adhesion interface:

----O------O------O------O------O------O---
O------O------O------O------O------O------O
----O------O------O------O------O------O---

Blending the Z-offset up from zero from the bottom/initial layer and down to zero approaching the top layer will perhaps serve to ensure minimal disruption of the surface layer quality. Such Layer Interlocking would likely only have a minimal impact on X and Y surfaces due to the sideways squishing effect of the nozzle as a line is laid down.

If it's necessary for the original Z-offset functionality to be retained for probes, perhaps this idea could created as a separate plugin with a separate Z-Offset value specifically for this purpose or even just set the offset to be half the layer height??

Non-zero value results in printhead starting ~75mm up the Z axis

I installed the z-offset plugin from the market place, set it to 1.7mm(imported from S3D), and its behavior is to attempt to print ~75mm off the print bed. Seem to happen on any non-zero setting. When loading the preview in flashprint, the print does show on the bed.

Printer is a flashforge adventurer 3

Setting to zero, or uninstalling the plugin results in normal printing behavior. But I still need to be able to adjust it for my use case

Z-offset amount does not affect Cura's default start code

i'm not sure if upgrading to the latest version of Cura changed anything, but around the same time, I started having problems with the default line Cura draws in its start code - it drags against the bed and is way too close. i can edit the gcode or have separate printers, but between printing with and without painter's tape, this is annoying. would be nice if there was an attribute i could use in gcode, or the plugin considered the start/end gcode cura uses.

Doesn't seem to be enabled in Cura 4.4

I assume it isn't compatible with 4.4. If I go to the installed plugins and check it, it just goes back to being unchecked when I restart Cura. This is a very useful feature in Cura. It saves me from needing to use the very long and inaccurate bed leveling procedure built into my printer.

Z-Offset only for the 1st layer

Hi,
I think the actual behavior of this plugin is to apply a Z-Offset for all the print.
Would it be possible to use/modify this plugin to apply a Z-Offset for only the 1st layer (or a defined number of layers)?
Kind regards

Z-Offset not working in Cura 5 Beta

Hello,
I know this is quickly after the beta release, but I wanted to let you know that Z-Offset plugin is not working.

[Feature Request] Multiple Z-offsets in a grid across the bed to "flatten" the print area with linear extrapolation

I was looking at your _filterGcode code and it could be easy to add linear extrapolation across a distributed grid of Z-offset samples, because you already adjust all Z values in G0/1 calls from the adhesion_z_offset config value.

The _filterGcode function would be extended to support Z-offset extrapolation based on X/Y values: By simply adjusting the Z value of G0/1 calls based on the grid, the printer will do the point-to-point linear extrapolation for us. For example, adjusted_z = extrapolate(X, Y, Z, ZOffsetSamples) where X, Y, Z are the original G0/1 coordinates and ZOffsetSamples is the sample grid.

More background (mostly copy-pasted from my stack exchange post):

We have a Tronxy X5SA 400 Pro which uses a TR sensor to "auto-level" the printing bed. It samples 16 positions across the bed (4 x 4) and provides a +/- level from its initial measurement. For example, it might produce a grid like this:

+0.280   +0.155   -0.108   +0.127   
-0.267   -0.010   -0.005   -0.218   
-0.114   -0.020   +0.004   +0.000   
-0.143   +0.110   +0.253   -0.270  

As you can see in this contrived example, measurements toward the center are closer to a Z-offset of 0 because that is what it samples first; toward the edge, it can be off by ~0.3mm. By turning the sprung leveling screws, I can usually get it to within 0.250mm across the bed.

However, 0.250mm variance is still too much for 0.1mm-layer prints because at the center it is right on, but on the edge it is 2-3x the layer height above the bed...or worse, in the opposite case, the head will crash if the bed curves in the +Z direction; thus, I have to babysit the first layer and manually +/-Z as needed.

Prints in the center of the bed are great, but adhesion can be poor on the first layer when it prints near the edge, and part thickness can be off by ~1-3 layers.

Questions:

• Configuration: What would be the best way to provide the Z-offset sample grid as a configuration setting to Cura? Here are some ideas, but I'm not stuck to any of them:
  • Add a Cura option that points to a JSON file with a 2D array of (X,Y,Z-Offset) tuples for each sample. Then the user could have as many Z-offset samples as they wish. (In our printers case, it is always 4x4.)
  • A long list of 16 (4x4) config options like adhesion_zsample1_1, adhesion_zsample1_2, ... adhesion_zsample4_4. This seems cumbersome and does not scale, but it is possible.
  • Have Cura do the Z-offset sample scan itself. Is there G-code that could read the TR sensor value to do our own scan over USB serial? The M102 command looks promising, though I've not tried it yet. I like this option the best, maybe coupled with the JSON file (or some Cura-specific object storage) if it works.
• Other considerations?

Z Offset plugin in Cura

I have an Anycubic predator and I have come up with an odd issue that I believe your Z Offset plugin for cura (which I love and think is an absolute necessity) is causing it.
In cura using any variation of the draft 0.2 profile works great for printing.... If I switch to the Normal 0.15 profile or 0.06, my predator goes to the glass to start to print and then the head goes AWOL every time...it lifts off the glass and starts to print in the air in at all different angles and heights... But if I switch back to a 0.2 profile again (custom or standard) it works fine....

After hours of troubleshooting I found the issue. It is caused by the Z Offset plugin which I have used for a few months and really like. I guess with the update to Cura 4.3 the plugin works fine on layer settings 0.2 but if it is any smaller my predator printer goes rogue. If I set it to 0 everything works great using any profile layer height but then I have bed adhesion issues. Cura 4.4 does the same thing.

Is there more information that I can give you to help fix the plugin. It is something that I use all the time.

thank you so much for the work you put into the it is a huge benefit to us new to 3d printers

Cheers
Michael

Z-Offset in Per Model Settings

I like to be able to set separate Z-offsets with the "Per Model Settings" option to be able to test different offsets on different test patches but the option is not visible? I have checked the "Show all" checkbox and i already have all options visible under Setting Visibility. I'm running Cura v5.5.0.

Manual

Sorry to be so obvious but more for those that follow my question too ...

I presume this is the correct location for your Plugins value to be input?

Does my 0.5 value here mean it moves the nozzle Away from the Bed b y 0.5mm?

What is 'Extensive Z Offset Processing' for?
Is this your Plugins setting or CURA's?

Very hand plugin, didn't initially show up in 5.2.1 after update

Had to uninstall and reinstall and then back to perfect.
Interestingly the Z-offset was still set for the printer in question.
Very minor issue but might be worth a look?

Only offsets 1st layer, not others

This plugin only makes Z Offset for first layer only (on the buildplate), not the other layers.
Ie. if original layer height is 0.2 mm and offset is set to 0.2 mm, first layer prints at Z0.4 (correct) but others print like nothing has changed, so its: Z0.4, Z0.6, Z0.8 etc

That means I can't keep a nozzle all the time during print above whole object. Which solves nothing for materials like PETG which likes to be „airprinted“. After some time, usually bigger print, there is so much material on the nozzle that it starts to be clogged and later it will leave huge marks of collected material from nozzle on the print.

So for correct PETG printing I have to recalibrate buildplate manually anyway.

Not an Issue, But: Just to Clarify?

If I the z-offset is set to -4.35mm in the marlin firmware; Initial Layer Height is set to 0.3mm in Cura; and I set this z-offset plugin to -0.05mm, this would be the equivalent of setting the marlin firmware z-offset to -4.40mm, right? I have to print PETG 0.05mm closer to the bed for good adhesion and it would be great if I could have this set in a Cura PETG profile so I don't forget to do it when switching from PLA.

Z offset under Materials Print Settings Tab?

Is it possible to have the Z offset listed under the printer settings in materials? I have a couple of different materials that I have added with different temperature settings that require a different z offset value. The material setting make adjust automatically so it would be great to enter the value once and every time the filament is selected the value gets changed. Not sure if this is possible but it would make things nice.

zoffset setting grey / inactive

Hello,
since i switched from Cura 4.6 on windows to Cura 4.7.0 on linux
the offset plugin does not work for me anymore. its option is grey

Z Offset Value not showing in 5.7.0

It appears that since upgrade the z offset value is no longer showing, have tried removing an re-adding to no avail?

z-offset setting not visible in 'per-object' settings

The ui is not revealing the z-offset setting. It is visible and functional under the normal (global) settings.

Not sure if this is a limitation with Cura, but if not, this would be an absolutely killer feature for my very-large-print-bed levelling procedure. I'm currently manually editing a series of squares and it's very unruly and error prone as the repetitions grow.

(if you're interested, I'm printing a series of squares with z offsets of +/- 0.05mm, at a series of probe points, then manually adjusting the UBL grid based on real-world results. It's working splendidly but is such a pain to manually set up for each grid size, filament, temperature, and a handful of other variables)

Cura 5.6

plug-in is not supported Cura 5.6 ?

Printer resets on first print

I'm using Cura 4.6.1 with Octoprint v1.5.3 on my Ultimaker 2+ and Ender 3 Pro. I noticed that after installing the Z Offset plug-in, every time I begin printing the first time since the printer is turned on, the printers disconnect from Octoprint. This has been going on consistently ever since I installed the plug-in.

Option to not shift coordinates.

It's possible to just pass offset value to macro in start gcode without inserting coordinate system shift?

Cura 4.5.0 will not save gcode when z offset used

Application version
4.5.0
Platform
Manjaro 19.0.2 Kyria
Kernel: x86_64 Linux 4.19.113-1-MANJARO
Printer
Does not matter

Reproduction steps

1. Installed z offset
2. Set z offset to 0.1mm
3. Sliced Gcode - everything looks fine but can not save gcode
4. Error in terminal see screenshot

Screenshot(s)
(Image showing the problem, perhaps before/after images.)

Logs
2020-04-06 13:45:35,281 - ERROR - [MainThread] UM.Qt.Bindings.OutputDeviceManagerProxy._writeToDevice [144]: adjusted_z = round(float(result.group(2)) + z_offset_value, 5)

2020-04-06 13:45:39,218 - DEBUG - [MainThread] cura.AutoSave._onTimeout [60]: Autosaving preferences, instances and profiles

Additional information
If z offset is set to 0 it works fine but when it is set to 0.1 and I use 0.8 mm nozzle it throws this error

After installation on Cura 4.7 cura crashes continuously

Cura crashes after loading Any stl file.

Not exactly sure how this happens, i've looked through the code and can't see where it happens yet, but it happened on both windows 10 and mac.
I am also unable to reinstall as it makes a change Somewhere that stays even after uninstallation of Cura 4.7 and reinstallation on both mac and windows.
Cura was working fine on both Windows 10 and Mac until i installed this plugin.
Any chance someone else is having this issue?

Z-Offset incrementing in some situations?

Hi, thanks for a really helpful plug-in.
Printer Ancubic i3 mega s, BL-Touch , Cura 4.8.0, Octoprint
I can adjust the distance nozzle to bed by applying e.g Z-offset -0.1. It works fine as expected.
When the print finishes and I do the same print again starting from Cura it seems the z-offset is subtracted again. Like Z-offset -0.2.
So the nozzle is closer to the bed.
It does not happen when the printer is switched off. It does not happen when I do auto bed leveling.
Is this possible or just my feeling? Can I get the actual z-offset by a marlin command ?

Cannot see the plugin it the settings

Offset Issue with Cura 4.7.1

Using a Z offset sets the offset incorrectly. I used a 0.1mm offset and it printed at a couple of centimeters which caused the print to fail.
