Marlin: Question re UBL and upgrading firmware
Hey guys,
I'm going to be upgrading from 1.1.4 to 1.1.8, and was wondering how to port across my UBL.
Is it just a case where I select the mesh from EEPROM? Or do I have to redo everything again?
Many thanks!

One way of saving and restoring the mesh is to run G29 S-1 - this will print out a bunch of M421 commands to recreate the mesh. Copy and paste them to a local file, and then replay them when you've upgraded the firmware. It's a good idea to turn off temperature auto-reporting with M155 before doing this to avoid getting temperature messages in the middle of your mesh data:
M155 S0 ; Turn off temperature auto-reporting
G29 S-1 ; Print out the mesh
M155 S5 ; Turn temperature auto-reporting back on
I'm not sure if the mesh format has changed between 1.1.4 and 1.1.8, if it hasn't you may not need to do this (the mesh is stored at the end of EEPROM so it shouldn't be affected by a firmware upgrade) but it's a good idea to save the mesh anyway just in case.
