Firmware 2 to 3 with BLTouch Help.



  • Hay all,
    I thought i would give firmware 3 a go on my Duet WIFI (1.02)
    and with the naming of things i just wanted to see if i have got it write.
    Before i take the plunge, my main problem is the BLTouch
    Using BLTouch Guide

    Please read the wiki page on connecting a Z probe. I updated the BLTouch instructions to cover RRF3 a week or two ago.



  • Oh awesome i somehow missed that,
    Okies that makes more sense then.
    Only thing i am having trouble is with the M950 S0 C"duex.e6heat"
    I dont have the deux bored so i have wired it to pin 31
    the wiki says it pin name is.
    exp.heater7, exp.31, !duex.e6heat, !duex.pwm5
    would any work or would i ahve to use exp.heater7?

    Sorry for all the questions. I just like to be sure.

    Oh just a thought the Z Probe Mod pin could the could i connect the yellow wire to Z Probe Mod and use M950 S0 C"zprobe.mod" instead of pin 31?

    You don't have a DuetX so you are connecting directly to the expansion header. Therefore you should use exp.heater7 or exp.31.



  • I assumed so, but better for clarification.
    Thank you so much for the time and help.
