I messured the resistance of the MK52 at 25°C,50°C and 100°C and calculated the values.
Which ended up in this configuration.

Hi the documentation on: https://github.com/Duet3D/RepRapFirmware/wiki/Building-RepRapFirmware
is outdated

Error: `brew cask` is no longer a `brew` command. Use `brew <command> --cask` instead.

so you have to use:
brew install --cask gcc-arm-embedded

instead.

Same for the rest

@facet most of the VFA comes from non geared BMG gears. (used on the prusa mk3)

They also get less visible when printing over 60mm/s

When the on screen keyboard plugin is activated then the syntax highlighting is broken.

When i deactivate it then it works
tested on 2 mini5+ one with 3.4.0 one with 3.4.3.

What would be also great:
The option that the onscreen keyboard is only activated below a set screen resolution.

@moth4017
this is my config and it works nice

@egon-net i am using the Zimple Ziflex PEI powder coated sheet.
it sticks relatively good with a brim.
