Code issue in clearance variable

[Eremius]

I am receiving an issue from Klipper
Unable to parse option 'clearance' in section 'z_calibration'
In the autoz.cfg file the line is
clearance: 2 * z_offset from the "probe:z_offset" section

I am using a euclid probe. I am not sure if this matters but he euclid probe include (which contains the z_offset value) precedes the autoz.cfg include.

I did just notice that all the text after clearance is lt blue instead of the orange

I suspect this is a python spacing issue but I am not sure what it should be.

...and the log seems to show it's a casting error

Hi, this is the default from the documentation. You need to define a (float) number if you want a different value. And please use the safe_z_height property since clearance is already deprecated.

[Eremius]

Should this value be picked up automatically by default or do you need to explicitly set it?

[TitusLabs]

If you do not include this property in your config file, the default will be used (in this case two times the z_offset of your probe ...or 3mm if your probe does not have a z_offset). Or it is the value that you use with this property.
