Ender 3 and BLTouch
Hello I have a problem with my Ender 3 motherboard v1.1.4 and BLTouch v3.1
After installing BLTouch and flashing the firmware from the web (Ender-3Marlin1.1.6BLTouch.hex) as seeing in the official video and in the instructions delivered with the sensor, the screen it's black, it doesn't power on.
If I remove the pinboard and I connect directly the screen it powers on but there is a noise from the speaker.
What is the problem?
Thank you, regards.
Hello @admin I will try today.
Thank you very much.
Hi @bluefish, please upgrade the firmware and install the BL touch as follows, plus:The display cable needs to receive the EXP3 interface
