Hello all. I have a PRUSA printer that was down for some time, they are not so easy to trouble shoot! So in the interm I got an Ender3 which turned out to be a good little printer! I wanted the auto bed leveling so I got a BLTouch and was it a PAIN to upgrade!! There are a lot of things they don't tell you. So, for those of you into 3D printing and are interested I documented my process step-by-step on the upgrade, note -I have 3 friends who have used my document with success-, and am uploading it for you to use. Have fun and good luck.
