Calilantern is a calibration STL and calculator that looks a bit like a lantern, designed to help you with printer calibration and testing. Included is a 30 page written guide and an advanced calibration calculator to identify and correct scale and skew errors. If you're familiar with my first calibration STL, Califlower, then you'll feel right at home with Calilantern. It's similar, but better in so many ways as I've taken many of the things learned from that design and implemented them here.

Note: the ODS files have been fixed. We recommend using LibreOffice.

Calilantern Vs Califlower

While there are many little changes here are the biggest improvements you'll enjoy:

Calilantern now works in all three planes, XY, ZX and ZY where Califlower was only XY.

Iterative skew calibration allows you to input current skew settings and improve step by step.

Integrated calibration score to help you understand performance and share or compare with others.

A super detailed 30+ page written guide to help you measure, understand, and correct any errors.

More advanced measurement status monitoring to help ensure you get the right measurements.

Full support for Marlin, Klipper and RepRap Firmware.

Support for scaling size less than 100%

Change logs will now be published in the guide document so you know what changes with updates.

Still only needs a pair of callipers to measure!

This is not an update to Califlower so no free upgrades for existing purchases.

Latest Version

If you purchased Calilantern 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 login and visit the downloads section of the account page.

Further Information

Please 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 this?

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.

Works like a charm

The Calilantern did an excellent job. I've been testing the boundaries of precision and accuracy with my printer, and this tool proved to be an easy and successful method to calibrate my setup that drastically improved my prints.

I ran into an issue with the Excel file not working and it was fixed like a day later like magic, The developer is over here reading my mind.

This thing is great from the all points of view. Very nice figure design that allows you easily take the precise measurements. Also the spreadsheet is fully automatized, you have just to insert there the dimensions, then copy the commands for your printer.
p.s.
My Qidi q1 pro with the factory settings received 820 score.

It's a print that helped very little. Confusing spreadsheet and V3D has not answered questions

It's alright but the spreadsheet is confusing at times and the skee doesn't change unless you add the numbers (whichever ones you need to put in to adjust it) are entered. Very frustrating. Also frustrating that there is a ZX field but ZX is no where else on the sheet. It will probably work but this version seems like it is the beta version. Oh...and I've tried reaching out to ask questions about what goes where in the spreadsheet and it has been 3 days only to hear crickets. I hope others have had better luck but at this point I have only wasted a bunch of filament and my most precious commodity...my time that could have been easily fixed with a response to my question before I wrote this review. But anyways good luck.

Hi James, It sounds like you could do with a helping hand. The calculator has had many successful users so its not missing anything ZX, but yes you do have to modify the printer data with the numbers provided in order for changes to take effect. I've not seen any emails from you, in orbox or spam, so perhaps the form submission didn't complete. Happy to help if you can try again.

Useful tool, from all I've seen. Prints well and the Sheet works as advertised. Haven't needed to calibrate yet, but this will definitely come in handy once I do.
