Teaching Tech | Firmware retraction: Why you should try it out @TeachingTech | Uploaded 2 years ago | Updated 2 days ago
I’ve wanted to try firmware refraction for a while and I’ve finally gotten around to it. Most folks probably haven’t even heard of it but it may in fact be just what you need. In this video, we cover what retraction is, how it is traditionally handled by the slicer, how firmware retraction differs, and how to set it up. We then explore the advantages and disadvantages based on the entire process.

Thanks to my patrons who discussed firmware retraction with me to help flesh out the arguments for and against. I guess now I have to add support for it on my free 3D printer calibration website: teachingtechyt.github.io/calibration.html
