I flashed the latest 8 bit firmware and then updated my Cura settings to include the ABL code. Since then, I have been able to have it behind me while working, playing games, etc. So I defined the offsets #define NOZZLE_TO_PROBE_OFFSET { -44, -7, -3 } like this, but when i G28 and then G29 the BLTOUCH … When we are talking hours or days to complete a large print, a couple minutes tied up in bed leveling is not a big deal to me. I received the BL Touch Kit and overall I am very happy with the quality of the physical hardware. And if you do touch it, be very gentle, in order to not bend or push anything. I cannot find any X_PROBE_OFFSET_FROM_EXTRUDER options in marlin. I have reprinted the Fan Shroud mod and the layer lines are consistent, and don’t show any signs of leveling issues. This value will be adjust later on, to match our setup. Power peak 300mA. Make sure your homing macros use G30 to home Z and not a G1 S1 Z movement.

During the pandemic I have had a lot more time to work with my Creality Ender 3. Great guide for using the z-min for the BLTouch in the video here by Ted Marozzi Dai Hai Zu's video here is a comprehensive guide to installing TMC2208 stepper drivers This is a great diagram of the board, from Korobok at Thingiverse.com (note that this is for the original board, not 1.1, but all pins but the servos should be the same): I was feeling punched in the gut at this point, but continued to dig.
