Manual Mesh Bed Leveling

[shadowfiend 9]

Hi firmware gurus!

 

So I have been having problems with bed levelling on my UMO with official heated bed upgrade and strongly suspect that the glass is not flat.

 

Then found this video and it blew my mind!

I have searched for any info on someone doing this on an Ultimaker Original, but can not find anything.  I recently updated the firmware over USB from Cura latest version I think.  From the Ulticontroller:-

 

Firmware version

Ultimaker: DEV

In the video they guy says to search for Mesh Bed Levelling in the configuration.h tab (from Arduino software) and enable it there.  I did this but there is no Mesh Bed Levelling in my version of the firmware.

 

So my questions are:-

Has anybody done this and would anybody be able to explain how to do it please?

 

Many thanks in advance.

 

Cheers, Ian.

you'll need to build from mainline marlin the grid based leveling was never merged in and the new S5 does it before the data goes to marlin. have a look here: https://github.com/MarlinFirmware/Marlin

 

You might need to take configure quite a few settings for it to work on your UMO though, if you don't know what you're doing I would recommend getting help from someone that does.

From what I remember looking at the code I remember there were some inconsistencies which is why we didn't use it.

Hi robinmdh,

Thanks for your reply, I know that there are a couple of online firmware builders for the UMO and might have used one before, although I can remember any details.

 

So I'm guessing that I would download the latest firmware build from GitHub and use an Ultimaker firmware builder to make it compatible.  Was this your line of thinking?

 

If anybody else has managed to implement Mesh Bed Levelling on an Ultimaker Original, I would be grateful to hear your experiences.

 

I have an Arduino sketch saved on my computer, so I'm assuming, that if anything goes wrong I can just re-upload the image.

 

Cheers,

 

Ian.
