Califlower Calibration Tool

Thankyou for your interest but we no longer stock this product.

See the new Califlower Mk2 here: https://vector3d.shop/products/califlower-calibration-tool-mk2

The "Vector 3D Califlower Calibration STL" is an STL file and calculator to help you with printer calibration and testing. Included is documentation in the form of a spreadsheet calculator to identify and correct printer scale and skew accuracy. Includes the Califlower calibration STL file and Calculator Spreadsheet (in Excel and Libre office formats)

Slicer Compatibility

Size is typically fixed in the slicer, below is the compatibility chart

Slicer	Fix Size	Ease
Orca Slicer	Yes	Easy
Prusa Slicer	Yes	Easy
Bambu Studio	No (switch to Orca slicer)*	Not possible
Cura	No (switch to alternative)	Complex

*Orca Slicer can sign in with Bambu account and easily transfer all profiles and printers and works basically the same, just better!

Firmware Compatibility

Skew is typically fixed in the printer firmware, below is the compatibility chart.

Firmware	Fix Skew	Ease
Marlin	Yes	Easy - Complex*
RepRap Firmware	Yes	Easy
Klipper	Yes	Easy
Bambu	Yes	Easy

*In some cases Marlin will need to be recompiled to add skew correction feature which can be a complex operation.

Language Note

If you work with a numerical system that uses a comma (,) as the decimal separator then you will find that the spreadsheet places commas where the firmware requires a full stop/decimal point. For example, 10.45mm will become 10,45mm. See this Microsoft help document on how you can temporarily change this to use different separators https://support.microsoft.com/en-us/office/change-...

Do you need the Califlower Calibration STL Tool?

There is only one printer that I know of currently that has an in-built method of skew correction which is the Prusa Research Mk3 and its variants. You could still benefit from the Califlower as a test to prove that the in-built method is working.

On the other hand, the Prusa mini, to my knowledge at this time, has no methods for correcting skew. You would need to break the appendix on the control board and write custom firmware to implement it. Again, you may benefit from the calibration flower as it could help in knowing the extent of the problem with skew, and may still assist in manual correction, it's just not as simple.

As far as I know at this time, most other printers are easy enough to flash firmware to, or have simple implementation methods for scale and skew.

If you purchased Califlower recently, and you just want the latest version, you can use the same download link in the order email, it will get you the latest version. Alternatively, you can login to your account and head to the downloads section on your account page to download the latest version from there.

If you purchased Califlower or 'calibration flower' from the old website then you can access the latest version from the downloads page on 'my account'. If you don't think you have an account, just use password reset and that should sort things out.

Awesome tool

Awesome tool and very easy to follow instructions.

Dimensions are accurate. Excel form is so comfortable.

Awesome tool. Worth the money.

If you only ever buy one model in your life: Make it this one.

Not only is this extremely useful, it is made with an incredible amount of thought despite its simple looks. There is a fundamental understanding of surprisingly complex concepts all at play here being neatly wrapped into a single print and a powerful calculator to do the work for you. It is difficult to express just how much it is actually doing, but its much more than you think. This is clearly made with a passion for the hobby and an impressive mind, CNC Kitchen's video breaks it down well. Understanding it is one thing, making something that does it and then calculates it for you is another. The value here is excellent as no matter how expensive your printer or filament is, bad calibration will bring it to its knees - so do yourself a favor, reward a man's hard work and save yourself time and material by doing it right.

Very impressive results

I just acquired a Bambu Lab A1 and although this machine prints beautiful parts out of the box, for my engineering prototyping needs I wanted to increase the dimension accuracy a notch. Buying an STL is a first for me and this was money well spent. I went from 0.44% and 0.27% error on X and Y axes respectively to 0.06% and 0.05% !!!

I simply added the correction % to the scaling factor in Bambu Studio and that did the trick. I'll run the test on all my spools and I'll manually add the correction before slicing every part. I wish I could simply add the settings to a profile, but that's already good enough for me. I highly recommend this product!
