BUG - Slicing Error with Cura 5.6.0

[digidiver11]

Cura Version

5.6.0

Operating System

Win10

Printer

My Printer

Reproduction steps

I had incomprehensible crashes when slicing my workpieces. After a long search, I found the cause in my self-written printer file.
As there is unfortunately no good documentation for this, I had taken many entries from other printer files and thus copied a faulty entry.

Many errors of this kind are in the file (and others) "ultimaker2.def.json":

Lines like this are wrong :

    "gantry_height": { "value": "48" },
    "material_bed_temperature": { "maximum_value": "110" },
    "material_bed_temperature_layer_0": { "maximum_value": "110" },

Probably also wrong:

    "machine_name": { "default_value": "Ultimaker 2" },

Das Problem sind "" bei den Werten !
Richtig müsste es wie folgt heißen:

    "gantry_height": { "value":  48  },
    "material_bed_temperature": { "maximum_value":  110  },
    "material_bed_temperature_layer_0": { "maximum_value":  110  },

Presumably too:
"machine_name": { "default_value": Ultimaker 2 },

Since I removed this "", my Cura has been running correctly again!

However, I was shocked at how often this error can be found in the printer files and other files.

I have a few requests, which unfortunately I can't answer myself yet, as I haven't been working with Cura for very long:

1. Finally a proper documentation, also with explanations on how to create a printer file CORRECTLY. I notice that a lot seems to have been put together here and that many users just copy the files together.

2. A possibility or simply a short guide to really remove ALL superfluous printer and filament files and much more.
   Many files unfortunately also contain many errors.

Thank you and I hope I was able to contribute to troubleshooting.

Hey @digidiver11 ,
Nice to hear that you managed to figure out the problem in your printer definition.
Please note there is a wiki section containing documentation such as https://github.com/Ultimaker/Cura/wiki/Definition-Files-Explained, beyond that you can always engage and ask the community for help.

As the document states, it's best practice to use fdmprinter.def.json as your reference. If you would like to participate in creating definition files you can always create a PR and the community will be there to test and provide feedback.
see #17576 as an example.

If you would like to have a custom version of Cura with only your desired printers and materials, you can do so by modifying and building your own personal version as Cura is open source. You can follow the wiki for how to get started. https://github.com/Ultimaker/Cura/wiki/Getting-Started

Hope that helps.
