The BEST Calibration Method Just Got BETTER

FYI: I mention in the video that there are no instructions, that's WRONG, there are instructions, really good written ones are included. Also, for those that have bought previously, you can login with the same email you used to purchase and you'll be able to get the latest version. One more thing, it looks like CURA now has per-material shrinkage compensation in the latest Beta version so I'll be sure to make a new update for that. (upgrades are free) Merry Calibration, and Happy Printing!

Percentage compensation in cura is actually on a material basis. You can add it to material settings and put it for the material you are using. You just have to add it as an option.

@Vector3D: Kind remark from an mechanical engineer: please don't advise calibrating machine settings on material base. Steps per mm should be calibrated with calipers, not with an actual print, because of the dependency of material flow, extrusion temperature and fan speed causing shrinking, with ABS shrinking in general... You get the point. I love your Califlower for material settings calibration though. Good job 👍 🙂

The Overhang & Bridging stls were/are extremely helpful. :) The overhang test helped nicely to set SuperSlice’s angle for overhangs as well as to see where cooling lacks. The bridging was a nice simple test. Sometimes all the really fancy ones just over complicate things. These were two simple stls that worked just so nicely. It will be disappointing to no longer have them included in our package updates. Sure they may lack the extra docs, but sometimes a simple stl is nice to have. :)

Fixed my dimensional accuracy issues on my BambuLabs P1S, Thank You!

Great work my friend. Very cool, I will try your new Califlower 👍

Thanks so much for this video and calibration method. You've put in a lot of time and thought and testing into this. Kudos and hats off to you my good sir! I'm printing the first one now!

I have been using the Califlower to commission my E3D TC. Incredibly helpful! And thanks for the tip on line thickness, I think it explains my slight discrepancy between internal/external measurements.

I'm happy 😁 Got XY down to 0,01 -0,01. and skew I/O to 0,00 -0,01 Before calibration they were -0,3 -0,4 and -0,4 - 0,27

Might make a Califlower coaster holder for the new apartment xD

Would be cool if you added a solid base layer so you could use the multitude of Califlowers printed as drink coasters.

Thank you for your work on this.

Note about Cura, the 5.1 beta DOES have shrink compensation for specific materials now.

All for the community 💸

This is super cool.

how about PLA vs ABS ? is I'm using ABS do I need to resize it by 100.5% ?

You cant set % shinkage per material in Prusaslicer but you can set it in Superslicer! :)

You appear to have all the information needed from inner and outer measurements. Is it possible to add extrusion multiplier adjustment calculation too?

I found this interesting enough I had to reverse engineer it myself. couple things: a) Skew the Marlin AD distance, 100*2^-0.5, doesn't that need to be scaled? That is the perfect value and the AC and BD are in a scaled space. b) if the Avg X Error and Avg Y Error are different wouldn't that indicate one of the axis has its Step/mm off. I'd expect them to be the same if only material shrinkage was at play. c) seems to me flow compensation could be calculated. Scale the measurements by the Shrinkage / Step/mm Then calculate the Inner/Outer Error off the new values. d) If you know Skew setting for a set of measurements. The new value is just the sum of the measured angle and the prints skew setting angle.

You mentioned Pursa Slicer and Cura. Is this something that would be worth while for a Bambu? Namely PS1?
