Hi All
Been struggling a little with a BLtouch on a custom machine build using a Duet 2 Wifi and RRF 3 firmware.
Sometimes I know it can be frustrating just wanted to share a known good configuration here in case anyone needs some plain configuration.
Just going to post my configuration here in case others want something to reference that is working. All this is done on RRF 3
My Black and white BLtouch wires are plugged into the BLTouch plug next to the DUET screen plug, the Red and Brown wires are on pins one and 2 of the expansion connector and the SIG or yellow wire is on pin 8 of the expansion connector.
If you need any other help just let me know.
