5axes/calibration-shapes

A Cura plugin that adds simple shapes (cube, cylinder, tube) and also 24 Calibration and test parts + 7 Postprocessing scripts

Calibration Shapes

This plugin adds a menu to create some simple shapes to the scene (cube, cylinder, tube) and calibration sample parts. They are used most of the time to create some fast test parts and common calibration/test parts.

The default size for all the simple shapes is 20 mm, but can be modified via the Define default size menu.

Calibration part

You can also load standard test / calibration part :

All the parts have been designed via OpenSCAD. OpenSCAD can be downloaded here

Define default size

The function Define default size gives you the possibility to change the default size for the standard primitives (cube/cylinder/tube).

This plugin is using the Trimesh library to create simple shapes and to load STL files.

Cura-Postprocessing-Scripts

Several postprocessing Scripts are included into the plugin to help the user to generate automaticaly the differents Towers.

• RetractTower.py
• SpeedTower.py
• TempFanTower.py
• FlowTower.py
• MaxFlow.py

Copy Scripts

These scripts can be copied into the scripts directory via the function Copy Scripts.

Note : Since Cura 4.9 you don't need to use this function anymore. Has been removed from the menu.

After you have copied these scripts, you must restart Cura to see the scripts in the postprocessing scripts list.

Tower generation scripts

The scripts provided with this plugin must be visible in the Postprocessing scripts list.

SpeedTower.py

calibration-shapes's Issues

Copy scripts not available

I just installed the plugin, and have rebooted Cura multiple times. But the copy scripts option does not appear in the drop down.

Pressure Advance Wiki

I followed the instructions for the pressure advance and when I printed the test cube, there was no apparent difference in the corners. There were suggested settings, but nothing indicating what values you should change if you need to go beyond the suggested range.
I am using an Ender 5 Plus with SKR Mini E3 board (LIN_ADVANCE is enabled) and stock extruder my Cura Speed Tower Script settings are:

Command: Marlin Linear
Starting Value: 0.1
Value increment: 0.01
Change Layer 1.0
Change Layer Offset: 0.0

My Slicer settings are:
.4 Nozzle
Layer Height .2
Initial Layer Height .2
Line Width: .4
Top Thickness : 0.8 mm
Bottom Thickness : 0.8 mm
Infill Density : 0%
Print Speed : 100 mm/s
Outer Wall Speed: 100 mm/s
Inner Wall Speed: 100 mm/s
Initial Layer Speed: (leave it as your profile defaults)
Acceleration Control: Disabled
Jerk Control: Disabled
Coasting: Disabled

Scripts do not work when Relative Extrusion / Special Modes is activated

When the setting "Relative Extrusion" is activated in "Special Modes", the script for Retract Tower does not work.

"Relative Extrusion" puts in commands like "G1 E-0.6", so it should be easy to fix as you only need to replace the -0.6 with the current value.

One more sidenote: if you enable Retraction and enter a Retraction Distance of 0, Cura does not generate any retraction commands at all, so the scripts do not work. You have to enter a value >0. Not sure if you can show a warning from the script, but it would help finding the mistake ;-)

Adding the calibration objects doesn't work on Linux

I'm testing the plugin on Fedora and the second set of calibration objects (Calibration cube, temp tower, etc) are not loaded when clicked.

The logs show the following:

Copy Scripts does not work

After updating Calibration Scripts to 1.2.2 the copy of scripts does not work : seems related to a sub directory as shown on screenshots

DimensionalAccuracyTest - Imported model doesn't match wiki width

When you import the model with Cura, the bottom width is 25mm and the top width is 2.5. The wiki indicates that the models should go from 30 - 5.

Wrong instructions at the Acceleration page

The instructions for Jerk and Acceleration says to leave them on for the test, but it they are on, they overload every change in the layer:

;TIME_ELAPSED:623.259693
;LAYER:25
M117 INDICATOR-Layer25
M117 DASHBOARD_LAYER_INDICATOR 26
;TYPE:CUSTOM VALUE
M205 X10 Y10
M117 Jerk X10 Y10
M204 S500
M205 X8 Y8
;TYPE:WALL-OUTER
;MESH:AccelerationTower

The M205 X8 Y8 is set by the Enable Jerk Control setting and is overloading the previous M205 for the test.

Wiki entry on Linear/Pressure Advance Tower

I was doing another calibration print, and realized there was section that I left out when initially writing the documentation. When changing print settings, Cura changes outer_wall_speed to be half print_speed, which can cause some problems when testing linear advance on the outside of the test print. I modified my fork of the wiki to include a paragraph about this, and I believe it also decreases the print time, but would love independent verification on that.

Acceleration Tower script using deprecated M204 syntax

Noticed that the Acceleration Tower test did not show any changes to the print at the layer changes, and found that the script is adding the following lines:

M204 S400
M204 S450
etc.

Checking the Marlin Wiki, this syntax is deprecated, and is likely why this is not having any effect: https://marlinfw.org/docs/gcode/M204.html

How do you use temp tower script?

I see the TempFanTower script in the Post Processing menu, but I don't see how to actually generate and add the model which uses these values.
Please advise

[New feature] Add a calibration shape for bed first layer

Hey,

I'm fond of your plugin for Cura, that I go to for anything related to calibration!
And I'm wondering if at some point in the future you could add a shape for the calibration of first layer/bed leveling?

Something along those lines:
https://www.thingiverse.com/thing:34558
https://www.thingiverse.com/thing:4714033
https://www.thingiverse.com/thing:2280529
https://www.thingiverse.com/thing:1306709
Or whatever you would deem as fitting the purpose.

Maybe it already exists and I missed it. Sorry if this is the case.

Many thanks.

Overhang test

One Idea of modification could be to use something like this one : https://www.thingiverse.com/thing:2972495

Display details on LCD functioning incorrectly

You can replicate this with a retract tower post-processing script with the said feature enabled. It works fine when you change retraction distance but acts up when changing speed. Some seemingly random values are displayed, it can also be seen in the G-CODE.
Here is layer 0 M117 command with retraction speed set to 5

M117 speed (5.0/5.0)

it seems to be fine for a few first layers, but at layer 8 it is

M117 speed F300
which just displays F300. You can take a look at the Gcode I compiled with this script, because I can't figure it out. also attaching a pic of a message that should be "speed 10" or something.

Objects are placed with their center on the buildplate

Cura version: Master

I don't have "automatically drop to buildplate" enabled, which means that the calibration shapes are created with their center on top of the build plate.

Since Cura loads all models with their bottom on the buildplate (even if the drop to buildplate isn't enabled), I'd expect the objects to always be there. It's a minor issue since it doesn't really impact the functionality of the plugin

Issue with Retraction Tower on Cura 4.8.0 / gcode "G1 EXX" lines?

Hi guys,

Thank you sooooo much for this amazing plugin where we find all calibration shapes instead of going here and there to get each and every one of them :)

I'm a beginner (got a CR10S Pro v2 a week ago), and using Cura 4.8.0. So I'm pretty sure what I'm describing is just because of my lack of experience/comprehension in 3D printing/Cura/gcode...

So:

• I calibrated my Sunlu PLA+ at 210° with a temp tower
• Then I went on with the retraction tower : test from 3mm to 7mm retraction
  
• After 30mn, here is what I get
  
• Surprise! I checked the gcode, and I don't understand how retraction is set on all the G1 lines:
  • First, I was expecting lines such as "G1 E-X" (where X goes from 3 to 7), but all I can see is

    Line 45: G1 F2700 E-7  
    Line 49147: G1 E-2 Z0.2 F2400 ;Retract and raise Z

• Second, each G1 line has a slight E increment, and here is an excerpt of layer 0, and last layer: it starts at E0.03135, and ends at E1379.74101

;LAYER:0
M107
G0 F6000 X125.272 Y136.534 Z0.2

Again, I'm pretty sure it's my lack of knowledge, so excuse me for bothering you as it's very certainly a lack of understanding on my side...

RetractionTower3-7.zip

Modified G-Code not included...

Hi! Love the tools, however for the temperature tower, the modified G-Code is not part of the project. The temp just stays the same as my cura settings. I'm on an Ender 3 V2 (running the Smith 3D software), with Cura 4.8.0.

I have installed the plug in
I have added the modified G-Code to Cura
I have restarted Cura.

Thanks for your help, and thank you for the plugin!

PETG Tower temp labels

I want to test my PETG starting at 250 and working my way down by 5 degrees.

Temp Towers: Gaps between steps make it unprintable

can't print the temp towers with the most recent version. The object has gaps/spaces between each temp step.

Scripts not showing up in the Post processing plug in.

I'm not sure if this is related to the other script issue posted a week ago by someone. I'm using Cura 4.9. I had no issue with earlier versions. but this one for whatever reason doesn't load the scrips from the /scripts directory or from the /plugins directory ( tried that as well).

If I: Add the scrips to the proper directory. restart Cura, new scripts are not available in the Post Processing Plug-in

[FR] Temp Tower script save settings with project

When opening a project in Cura that has the script enabled, it loads the values from the last time the script was used (not the last time the project was saved). This means that you need to document specific settings for each different temp tower and remember to hand-edit the script values each time.

IF there is a way in Cura to preserve the script values as part of the project, that would be VERY valuable. If not, then maybe there should be a bug against Cura to enable that option for your (and other) scripts that take parameters.

Thanks for a great set of calibration objects and scripts! They are SUPER HANDY!

[Request] Add Ringing Tower (Resonance Compensation)

Hi, I'm currently wanting to add ADXL345 accelerometers to my FDM printer.

For testings I need the Ringing Tower (https://www.klipper3d.org/Resonance_Compensation.html)
Would be nice if implemented into this superior plugin in the future.

After installing the calibration shapes plugin in Cura 4.8 and after restarting Cura

I installed the Cura plugin calibration shapes but after Cura 4.8 restart, i can get the Add a Retract Tower but when i go to Post Processing and Modify G-Code menu, i dont see the script for editing the parameters in the list of scripts. Operating system MacOS Sierra 10.12.6

Post processing scripts wont modify test object

Hello there!

Thanks for creating this plugin!
I tried to use the copy scrip and post processing to modify temptowers for fine tuning, but it doesn's seem to be making any changes to the object as well as the slicing. And I'm using cura 4.8 on macos. Is there some kind of settings I need to turn on?

Thanks.

No side pillars on temptower on latest cura

Hi, I just wanted to try this great tool.
Have an Ultimaker S5 and some TPU98 from RS with oozing problem and tried to use the temptower on extruder 1

Only the bridge, not the construction pillars are visible on preview using standard profile see screenshot. Is this a known bug o did I oversee something?

SpeedTower.py uses deprecated parameter for M204

According to https://marlinfw.org/docs/gcode/M204.html, M204 S<accel> has been deprecated. "P<accel>" and/or "T<accel>" should be used.

Help with Retraction tower

Little confused on the retraction tower script. How exactly are we suppose to config the values of the post processing script?

Can't find this once installed

HI,

It's probably just me but I've installed this and I can't find it.
I expected it to be under "extentions" but it dosesn't show. I've checked all the other menus and can't see it.
any help greatly appretiated..

I'm using a Windows 10 pc and just upgraded to Cura 4.12.1. I'm installing from Cura marketplace.

thank you for your help and time

kind regards

[FR] Maximum Deviation/Resolution Test

With a Maximum Deviation / Maximum Resolution test you could easy find the sweet spot between fine print and overloading your printer

Minor doc and consistency issue

But let me start with a big thanks. This is great work, put up a paypal button i'll give you a coffee.
My problem has often been that many towers and things require Simplyfied3d to slice or manual work.
And ready towers (gcode) are made for Cartesian printers, i have a delta and so they are out of the printing area.

Ok, the first doc issues i would change is: the links to say a temp tower in the readme go to the stl, but i think it would be more helpful to link to the corresponding wiki page. I can make a pr if you want

Second, the line height does not seem consistent, i have see 0.16 (temp) and 0.2 (retract) . Ideally the scripts would pick up and do the change accordingly. Failing that (too difficult/impossible) a consistent layer hight (0.2 ?) would be preferable, and mentioned in the readme.

So thanks again
Torsten

first to say: great plugin!!!

Would be nice if you can add more temp towers for different materials - but i think the big three pla / abs / petg is the most needed - so only petg is missing :-)

Feature Request: Multiple flow rate model in single print

The current flow rate model only adds single model to build plate and uses the current flow rate. Although it is possible to add multiple instances of the same model and setting per model settings for various flow rates. It would be great to do this automatically just like temp tower or retraction tower for example. The advantage is that one can know good flow rate for a model in a single print. Is this possible to implement?

Extreme extrude feed at end of retraction tower

When doing a retraction tower, just in the moment the part has finished I get a vary fast and generous feed on the extruder, so fast that even the extruder stepper gets blocked (e3d Hemera).

Help with flow tower

Hello! Great plugin, been using it a lot today and am now on the flow test tower. Saw someone else ask a question like this here so hope this is the right place. I read the wiki but wanted to clarify what I am looking for. Is it for the pin to slide in and out with no resistance, or to have some resistance but easily come in and out or to not come out but easily go in? I have 92-96 about the same , going in and out but but wanted to make sure those would be the correct ones because I [previously thought I had under extrusion issues so didnt expect a lower flow rate to work better.

Thank you! and keep up the good wokr

Store models in binary stl instead of ascii stl

As per title. Binary STL is much smaller than ascii stl. It won't make that much differnce for the small models, but it does add up for the larger ones.

Temp Tower 220-185, so what's 175 for?

I installed this plugin, and created the temp tower. I followed the guidance here:
https://github.com/5axes/Calibration-Shapes/wiki/PLA-TempTower-220---180%C2%B0C

When I inspected the gcode afterwards (to verify post-processing) I see the temperature actually goes down to 175.

Did I do something wrong?

Temperature Tower Walls Too Thin?

I am attempting to run the temperature tower for PLA+ and Cura is not slicing the entire model (Cura Version 4.12.1). From what I can tell it has to do with how thin the walls are on the Temperature tower? I am using a 0.4mm nozzle and have my line width set to 0.4 and this is what Cura does when I try to slice it. It does this with all of the temp towers. If I change the line width to 0.1 all of it will slice, but I do not have a nozzle that size.

I have been following this tutorial https://www.youtube.com/watch?v=EAG_538k_bM.

[Feature Request] Nozzle Offset Calibration (dual/multi nozzle)

Hi,

Thanks for the very convenient plugin. I appreciate your work.

Is it possible to provide a calibration pattern for dual (or multi) nozzle print head? It would be very convenient to have a pattern that helps me finding out the correct X and Y offset of the second nozzle.

The Problem

I built a very accurate switching extruder printhead but the mounted stock hotends seem to have a lower dimensional accuracy resulting in a serious offset (for example the first to second nozzle offset is x_offset=+1mm, y_offset=-0.5mm). The real offset I cannot measure in the CAD drawing. Instead of measuring with the caliper (and probably damaging/scratching the brass tip hole) a calibration pattern would be very convenient. Such a pattern could be inspired by the color ink printer calibration test.

Implementation Suggestion

The calibration pattern should provide a few pairs of X and Y aligned lines (or pads for better adhesion). The two neighboring aligned pairs are printed with T0 and T1 each. There should be more such pads per axis with a slightly incremented/decremented offset in their alignment, so that I can choose the correct one.

Usage Example

1. I set the assumed (as of CAD drawing) X and Y nozzle offset in the printer firmware.
2. I load the calibration pattern in Cura and use a post processing script for manipulating the X/Y offset parameters.
3. I start the calibration pattern printout.
4. I search for the best matching pairs in X and then in Y direction.
5. I update the offset in firmware with the new offset parameters.
6. I start a second printout for verification.

Use postprocessing scripts without copying them

It should be possible to use your postprocessing scripts without first having to copy them over and restart Cura. Cura should be able to find the scripts from inside your plugin folder if you move your scripts folder to into a folder named resources, and add this to your plugin initialisation:

Resources.addSearchPath(os.path.join(os.path.dirname(os.path.abspath(__file__)), "resources"))

This will add that resources folder to the paths Cura checks for script files.

Feature request: write text

Might not be a specific calibration thing, but would be used for calibrating different stls.

Usecase; i have multiple versions of the same item; for example scaled 99 / 100 / 101 percent for making a tight fit.
However, on the print plate it can be hard to see the difference between them. When it is using a different infill it's even harder since the differences arent visual.

It would help a lot to be able to add 1layer thick text-meshes, so i can 'annotate' on the buildplate next to the mesh and be able to see it next to the finished print a couple of hours later.
No need for special things as font etc, just a solid straight font like arial bold will do.

wouldn't M109 be more appropriate than m104?

wouldn't "M109 R" be more appropriate than "m104 S" in the tempfantower.py script?

this would wait until the temp gets to the temperature before starting the layers.

Temp tower script not working

In Cura 4.12 I am trying to print a temp tower but I noticed the script wasn't changing the temperature as it was printing. I checked it by searching for M104 and they are not being added that I can find. I see the temp is not changing on the printers screen as it prints

Scripts Do Not Work When Using Decimals In Change Layer Field

If you use a decimal in the change layer field the script does not process correctly yet the field defaults to a value of XX.X for entry. This affects multiple scripts including the Temp Tower and Retraction Tower.

SpeedTower script drop down command for "speed" is not showing up in Cura

I am running Cura 4.13.1 with latest extension. The SpeedTower.py script appears to be missing the option for speed.
I wanted to run a speed test with this model https://www.thingiverse.com/thing:3249901
But when I went to add the script it appears that I am unable to select speed as an option in the script.
