Now the Marlin3Dprinter video that cover the BLTouch is published. +Tony Gomes has done the narration.. Great work!!! I start to like the BLTouch.. Its small, accurate and light, I have used my BigBox printer to do the video. The BigBox uses a RUMBA board with PT100 apmlifier where BLTouch normaly is installed. The video covers how to move the BLTouch "servo" connection to another pin configuration.
