As the title states, the LCD fails to turn on then I have my BLTouch V3 plugged in to my EZBoard Lite.
The BLTouch is from the kit provided by Creality, it was working* on the stock creality board. (*sometimes it would fail halfway through levelling, red light etc.)
At first I thought it was the firmware, the same thing has happened with 3 versions:
- Test Firmware that was pre-installed
- Pre-compiled Ender 3 Firmware
- Self compiled firmware with BLTouch enabled + dual z motors enabled.
Everything works when the servo plug is disconnected, but if I turn the printer on with it plugged in I get nothing. I've double checked the plugs/polarity. There is a small chance the cable may be damaged as I've rewired things a couple of times, but it would only be a breakage on a single wire and not a short.
What are my next steps here? I'll probably just purchase another BLTouch but if there's anything else I can try I'm all ears.
