3D printer brand / version + firmware version (if known)

What 3D printer brand / version are you printing on, is it a stock model or did you modify the printer, what firmware is running on your printer, version of the firmware #s

Behavior

• Ever damn time I open the app the purge volumes are reset to 70/70 which is way, way to much for my setup
• Pretty please, keep my configuration changes...
  

Is this a new feature request?

Project File (.3MF) where problem occurs

Upload a PrusaSlicer Project File (.3MF) (Plater -> Export plate as 3MF for Slic3r PE 1.41.2 and older, File -> Save / Save Project for PrusaSlicer, Slic3r PE 1.42.0-alpha and newer)
Images (PNG, GIF, JPEG), PDFs or text files could be drag & dropped to the issue directly, while all other files need to be zipped first (.zip, .gz)

Closing as a duplicate of #2990. Current workaround is to keep a 3MF with your default.
