OK so I got the BigTreeTech SKR Mini E3 V2.0 32 bit board a few weeks ago. Installation was easy and it has been printing great AND quiet. I got the BL Touch kit yesterday. After finding nothing but bad info on Google on the wire position in the connectors I finally stumbled on a site that actually showed the V2 board and the same wire colors of the BL Touch I have I got it working. I manually leveled the bed and then let BLT do it's thing. After it going through all 25 sensing points I printed a small 10mm part. Huge failure. It didn't stick using hair spray and 55c bed temp. I printed another and looked at the nozzle height. It was at least 3-4mm above the bed. Neither the board nor the BLT have documentation worth a damn and there are SO many worthless YouTube videos out there. I'm sure it's a simple thing to correct the print height after BLT bed sensing. I just don't know where to start. Keep in mind that this is the latest 32bit board V2 and latest BLT V3.1. I'm pretty sure the BLT doesn't use any optics so I don't know how it could be a problem but I'm using a 4mm glass bed.
