This purchase includes one online support session of up to 60 minutes. We can work through printer setup, slicer settings, calibration, first layer, extrusion, bed leveling, print quality, and common print failures over chat or video. This is one session with a maximum of about 60 minutes, not unlimited support and not a guarantee that every issue can be fixed. Access lasts 7 days so you can book and complete the session. STL files are sold separately.
