I have an original Ender 3 that has been upgraded as follows:
Sprite Extruder Pro
The printer worked fine after I installed the new MB and BL Touch. After installing the new extruder and using the only firmware I could find that claims to support the touch sensor and Sprite extruder bed levelling doesn’t work properly. If I level the bed from the printer interface it goes through the mesh routine, but at the end it returns to the middle of the bed and drives the hot end into the build plate.
I have run the self-test on the BL touch and it always passes, so I don’t think it’s my sensor.
Does anybody have suggestions for where to find a known working firmware file for this configuration? I can’t believe that I’m the only person who has installed a BL touch and Sprite extruder on an original Ender 3.
