Chris I can't say enough about how much this has changed my printer. I got a new inductive probe and an SKR Mini E3 V2 and have been fighting getting the bed leveled. Even with an automatic 25 point probe before each print I was struggling to find the right height on my not-flat bed. I followed your instructions and the very first print nailed the first layer with no intervention from me. This has truly made a huge difference for me. Thanks for putting this together.

So I'm replacing my stock 8 bit controller with a 32 bit controller tomorrow...and I was preparing a marlin .bin for it...thank you so much for making sure that I do this project on *another* day. I'll stick with bilinear for now! Thanks! This looks amazing and stupid-easy once it's set up...but I really appreciate your video letting me know how many steps alone it is just to get running. I'm sure I'll be able to do it when I'm ready though and I've bookmarked this and subscribed just for how easy to follow this was!

You see chris, this is why the community needs you. You're the only one that I'm aware of that breaks down marlin in a such pleasing way. Easy to follow and covers all the scenarios.
Thank you

I regularly come back to this video if I need some help troubleshooting and/or re-leveling. Can't say enough how great this walkthrough is.

[ftcministriesworldwide]

Chris, all I can say is "Wow!" Thank you for taking the time to do this video. Wow!

[efnick]

This is one of the most if not the most comprehensive guide for UBL that I've seen. Thanks a ton! They should include this video to the marlin

Ive been fighting this on my second sv01 for months. Found your tutorial, and it is simply amazing how you go step by step, so no guess work needed. THANK

I just had to comment on how appreciative I am for your effort on educating us about 3d printers. You have got me through some hard times with setting up my printer. Little did I know the deep waters I was entering when I upgraded my ender 3 pro motherboard from a silent creality one to the skr 1.4 turbo. I had no previous experience with visual code or g-codes etc. But watching your tutorials with your easy to understand method of teaching has helped me much. I still have a long way to go but I'm starting to understand this stuff now and it isn't as daunting as when I began. Thank you.

Back in 2016 or so I was watching the Marlin GitHub issues and PRs daily. As I recall, Roxy was one of the key developers on this feature, and it was great watching the progress. I moved away from having a printer that used “straight” Marlin, so never got a chance to test the working version. Very impressive to see it all come together.

Hi Chris, just spent the last 2 hours playing with UBM, didn't know it even existed! thank you for the great content.

[NORMSTI]

your a genius, fired my printer up after not using for a year or more, and have spent two days of frustration, then found your video again. Thank you sir!

[GeekDetour]

Dude! Very nice tutorial - thank you so much! To me, the most important part was which GCode commands should be set in my slicers to load the mesh and compensate it just with eventual tilt changes. Thanks!

[jeduardob]

Chris, as always an excellent tutorial ... I have used your tutorial of bi-linear leveling and never failed. Keep up the great work !

[neuxstone]

I can't figure out why you don't have more subscribers than the typical Toy Boy maker channels...keep up the great "to the point" honest content.

[strangejmaster]

This video amazing! I was able to take some parts of it away and finally get UBL working, thank you!!!

[EddieRushing]

FYI the slots for meshes are numbered from 0 to 6. 0 being the first slot. Thanks for posting the video, very nicely done.

[mattv]

Some of the best 3D printing videos made! Added bi-linear to two of my printers using your how-to on the subject. May try this on my TEVO Tarantula that's due for a tear down. Keep up the great work!!!

[davidcgu]

One of the best tutorials I found about this topic, congrats, however there is a small note, pre bed leveling is required or you can face that sensor is not able to capture all points on the bed during process. Regards

[lewisheard]

Cheers dude, followed your step by step guide and breezed through the config! It took me longer to update to the latest marlin bugfix then it did to implement this :D

[matthiasgrimm]

Chris, thanks for this very good intro to UBL. I had it once activated but 'Real men don't read instructions' and didn't knew what to do, so back to bilinear ;) Just set it up on my Sapphire Pro (SKR 1.4 Turbo).
