Setting up bl touch



  • Help setting up BL touch on ender 5 plus v3.1.1 firmware.

    Hello! so im setting up my duet 2 wifi and ive got everything set up and configured except for the bl touch. In the configurator under the z endstop what do i select from the dropdown menu? zprobe active, low pullup? I have it wired like the guide suggests vor pre v3 firmware where the pwm control is on the exp board heater 3... Im not sure what to do with the modulation pin dropdown menu? Any help would be much appreciated.



  • in i/o mapping you must select a pwm control channel i.e exp.heater7

    then you can select bltouch under endstop - z-probe



  • @Veti thats the one part i know. i have exp heater 3 selected. There are several other dropdown options on that page i dont know what to select. Or do i not need to select anything else other than that one pin?



  • thats it. post your config.g

    It's unused in this case.
