It can be horribly frustrating if a 3D print that has already been going on for hours or even days fails and the printhead only moves in mid-air without printing anything. In this video, I’ll show you how you can easily resume one of these failed prints and save you a lot of time and money! Let’s find out more!

NOTE: This video covers the approach that works very well with GCode from PrusaSlicer and relative extrusions. If you're using CURA and notice that your slicer spits out absolute extrusion amounts (M82) then check the website article. The process of editing your G-code file might be slightly different!
