Hi All,
I have a DUET II Ethernet with a BLTouch Smart-3.1. The firmware is 3.2.
I believe I have it wired correctly in that I can successfully issue M401 and M402 commands. With the probe retracted the BLTouch is red. With the probe deployed the BLTouch is not lit.
When I issue a G30 command, the probe deploys and the Z axis moves down. When I tap the probe to interrupt the G30 command, the Z axis retracts 5mm and then begins to go down as it tries to probe again.
What information to I need to provide to assist with troubleshooting?
Thank you,
Darren
