In the process of updating my printer (Alunar M508), I decided to add "Auto Bed Leveling" using a BLTouch sensor. After doing a lot of Googling:
- I found firmware that will upload and work with printer in default configuration (without BLTouch)
- Adding BLTouch configuration, the software compiles and updates the printer, I see all new options in menu and BLTouch on "power on" does a self test.
I know I have configured the power to the device correctly 2 power sources and ground but where I'm having issues is in identifying
ZMax/Min on my board. So far the black and white wire are connected to Z axis "end stop" but I cannot identify where to connect the orange signal wire to. I cannot find pinout anywhere of this board.
