4.8.0 Extruder temp wrong and start script not included when wire printing enabled

[SmileyNeil]

Application version
4.8.0

Platform
Windows 10 Home build 19042.685. Nvidia GeForce RTX 2060 Super.

Printer
Creality CR-X (custom profile)

Reproduction steps
With gcode in printer's Extruder start script:

1. Set Material->Printing Temperature (and Printing Temperature Initial Layer) to 200degC.
2. Enable Experimental->Wire Printing
3. Slice

Actual results
With wire printing enabled:

• The extruder is not set before the material temp is set.
• The material temperature is set to 210deg, irrespective of the material setting (I tried 200deg and 230deg).
• The extruder start gcode is not inserted.
• At the end of the print the printer end gcode is inserted twice, with a zero bed and extruder temp in between.

Expected results

• The appropriate extruder should be set before the material temperature is set.
• Requested materal temperaure should be set, instead of fixed 210degs.
• The extruder start gcode should be inserted after the printer start gcode.
• At the end of the print, the printer end gcode should only be inserted once.

The wire printing is kind of a completely separate code path. These bugs don't surprise me in the least.

We've actually considered removing it completely because it's not working very reliably and causing a disproportional amount of maintenance for the usage it gets. So I don't know how much chance this will have to get fixed. The problems are pretty serious though, and it hasn't been removed yet. So we'll see what my colleagues think after their Christmas holidays.

Wiring printing has been removed from Cura.
Is this still an issue in current Cura versions (5.8.0 and up)? Can this be closed?
