Ender 3 Pro Adding BL touch to 4.2.7 board problems
I have an Ender 3 pro that I have upgraded to the 4.2.7 silent board. I now want to add the BL Touch system. I have downloaded the latest files from the Creality website:- 4.2.7 Ender-3 pro 32bit Marlin2.0.1 BLtouch V1.1.2without adapter board TMC2225. I have changed the pin outs on the plug to match the board as recommended elsewhere. Loaded this up and have the following issues: -
Auto Home only homes axis X & Y. When it comes to home the Z axis it drives to the centre of the plate, stops, deploys the sensor a couple of times and stops. Display reads 'STOPPED'. If I try to do a bed level it starts homing and stops again with display 'HOME Z '
When operated manually in Move AXIS X & Y operate correctly, however Z will only go up (Positive) and will not come down.
What is wrong here as I am losing faith in this equipment. This should be simple!
Thanks in advance
