So im sat at firmware 1.8 i think and noticed a variety of firmware updates and am concious that upgrading can be 1 step forward, 3 steps back! Im not reliant on the snapmaker right now for production parts and noticed the bed mesh error that it wasnt always applying the mesh compensation. After a brief skim read of the forum I was looking to settle on 1.12 firmware. Open to advice though from more experienced peeps who have been through the pain of updating and then rolling back!. Whats would you advise? ---

Back up M503 so that you can restore your customizations after upgrading. If you need to roll back it makes it easier too. Other than that, the firmware won’t permanently change anything that can’t be downgraded. Personally I’m still on 1.10, but I’ll probably be going to the latest version soon. ---

You should definitely upgrade from 1.8. 1.9 and 1.10s are fairly stable with a couple quirks that just make you have to power cycle occasionally. I’m still on 1.10.1 personally. Of the newer, sounds like 1.12.2 is the least problematic. Hopefully the latest, 1.15.2 will actually be usable. -S ---

Yeah, I typed in the latest Luban version, not the firmware. 1.13.1 is the most recent firmware. It reportedly has problems. -S ---

@sdj544 lol I really wish they would make Luban actually useful for something but it’s so simplistic it can’t do very much. ---

@sdj544 @brent113 Thanks for the responses… im thinking ill got with 1.12.2 then for now. In summary what was the bed mesh error issue and the stored mesh not being applied. does it make things better now. My 100point bed mesh level did seen to solve my issues. Also have they corrected the hot end values to represent the actual temps of the hot end 😉 Cheers ---

@chazr33gtr > [@Potential Issue with Bed levelling process](https://forum.snapmaker.com/t/potential-issue-with-bed-levelling-process/18649): > > It appears that the Snapmaker Calibration process measures the bed level at points that are materially different than those used in the levelling process when printing. I have been looking at this in conjunction with the work i have been doing on a glass leveling probe. If I am correct this may go some way towards explaining why many of us have had great difficulty getting a good bed level and the high incidence of burying nozzles into beds. I have made a note of why I think this to be the ca… As for the PID for the hotend and bed, it was supposedly fixed with 1.13.1 but everything else broke in it’s place because they can’t get it right when releasing a new firmware update.
