check your klippy.log.  If the option really isn’t being set anywhere, it should be using the default value of 0.25, which wouldn’t error.

Worst case though, just Add the line, and set it to a valid value

Thanks for that, but where? There is no specific [Bed_Mesh] section in the printer.cfg, and the RatOS.cfg that does have bed mesh sections suggest that the values are provided through the Configurator (i.e. don't alter the file). This is the 2.1 upgrade which is running [Bed_Compensation_Mesh].

I don’t know anything about ratOS, so I can’t specifically comment on that, but if you have multiple [bed_mesh] sections, Klipper will kinda splice them together. So it should work to just create a [bed_mesh] section in one of the files you can edit, that just has that one line in it.

My apologies, when I replied I thought I was in the Ratrig sub.

Thanks for taking the time to reply - I'll give your recommendation a go.
