I have got the Duet Wifi up and running and have been able to successfully print. Not wanting to rest on my laurels I decided to install the BLTouch. Unfortunately I have run into an issue where whenever I do a Z bed leveling the BLTouch errors (flashing red LED) and the Duet Wifi web console reads "1000" for the Z. My config.g sets: M307 H3 A-1 C-1 D-1 ; BLTouch - on heater 3 pin M558 P5 X0 Y0 Z1 H3 F200 T5000 ; Homing Z axis, P5 for BLTouch G31 X-22.00 Y7.0 Z1.5 P5 ; Set the probe height - reduced P25 down to P5 - no difference My bed.g is: G28 ; home all G91 ; relative mode G1 Z4 F200 ; move Z 4mm for clearance G90 ;absolute mode M401 ; In lieu of macro - call GCode for deploy probe G29 ; run auto bed mesh level M402 ; In lieu of macro - call GCode to retract probe G1 X10 Y10 F5000 When trying to run "Home Z" from the web interface the BLTouch extends its probe then goes into error mode when it's triggered. It either triggers immediately because the bed is not low enough, or if I have the bed manually lowered to begin with, it errors when the sensor triggers. When errored the Z on the web interface shows "1000". I should mention that my BLTouch is the version where the trace can be scratched to make it 3.3v. That said I had heck of a time scratching it (it's so small it's almost invisible). I have no idea if I was successful. It would be nice to know how to test that it's 3.3v? Secondary issue is that if I deploy the probe and manually trigger it with my finger, I get a reading (not 1,000) in the Duet Wifi Web Interface.
