One purchase equals one private 60-minute online troubleshooting session. Delivery is online. This is a one-time payment, not a subscription. It does not include STL downloads or Exclusive Updates. Scope can include failed prints, slicer settings, first layer, adhesion, basic calibration, extrusion, print quality, and general printer setup. This is not a guaranteed repair, not a guaranteed successful print, and not unlimited follow-up.
