This is necessary to ensure that all printers use a valid prime tower position, now that the position computation rule has changed and includes the base/brim.
CURA-10783
These are overrides of default_value while there is a value defined. As such these overrides had no effect at all.
Changing them to value can actually change the behaviour of the profile. That is not what the profile author has apparently tested with, so I'm not doing that. I'm just removing the unused data.
In the future if we get new definitions the author gets notified of the error so that he may test more effectively. The legacy can't be fixed without re-testing, so I'm leaving that to the authors.
Done during Turbo Testing & Tooling. I want to go home for the weekend now...
We had changed it for all printers back when we changed the prime tower position to a formula, but since then we've been getting new printer definitions that were made from templates floating around with the old structure.
We should really have an automated test for this.
Discovered during review of #6518.
Also convert the values for prime_tower_min_volume to make it behave similar to what the minimum volume used to be. This feature fixed a bug with the computation from volume to thickness. Now it's correct but we have to correct the old values to be still the same (approximately) as what used to be the end result.
Contributes to issue CURA-5457.
