Duet 0.8.5 and BLtouch 3.1
-
Hi all
I am using a duet 0.8.5 and I have also got a BLtouch v3.1. From the documentation on the 3.1 it says that it will now automatically choose either 3.3v or 5v logic. (The translation is a bit unclear but I think that's what it means) Am I correct in thinking I can go ahead and connect the probe to the 0.8.5 Z probe socket without any additional resistors or diodes etc.If this assumption is wrong. I notice the 0.8.5 has a 5v pin and grnd next to the power in, could I use that to power the BLtouch?

It should be safe to connect the BLTouch black and white wires directly to the ground and IN pins on the Z probe connector. You will need to supply +5V power to the BLTouch, and you will need to connect the BLTouch control input to a PWM-capable output on the expansion connector.
