  • i cant upload the picture
    when i turn on the power the bl touch have no response. the web show that i have already connected the duex5 Duet WiFi 1.02 or later + DueX5 (duetwifi102)

  • did you see

    Important: In the M280 commands in the following, leave out the I1 parameter if the BLTouch is connected to a servo output on a DueX board.

  • @Veti yes i see that and already confirm twice that my deployprobe.g retractprobe.g M280 in that don't include "I1"。before i bought the duex5 ,i have already test the BL touch in my duet2 wifi ,it works well

  • post your deploy and retract scripts

  • please post a picture of your wiring

    @tangougou does your BLTouch have a Red LED on, that lights it up like a Christmas Tree?! If not, it’s the +5V or GND wiring that’s not making a connection.


  • @droftarts when i don't use duex5 before. i have connect the bl touch in to the heater3 on the expansion 8 Pin it work well , it whs turn on the red led , but after i connect the bl touch into the duex5 and already reconfig the sys ,the bl touch was no led when i ture on the power , after i send M401 the bl touch was turn the blue led .

  • we really need to see a picture of your wiring. if you cant upload it here try something like imgur

  • @Veti i cant upload the picture , white connect Zprober in on duet2 wifi black connect gnd near the white ,

  • @tangougou it seems that i could upload pictures now~

  • thats E2 not E3 that you marked on the diagram.

    edit my bad that seems correct:
    For example, if the E2Heat output is unused, you can use heater 3 which corresponds to the PWM1 connector.

  • If you have a Duex v0.9 or v0.9a board, check that you have a jumper on the "5V AUX JUMPER SELECT PINS" between the 5V AUX and 5V INT pins

  • @Veti it seems that there is no jumper on the 5vaux and 5v int pins... two hours ago i used a multimeter to test the 5v pin but there is no 5v between the pwm1 5v and gnd pins

  • @tangougou

    did you place the jumper?

  • @Veti i haven‘t confirm that, maybe there was a jumper , the machine is on my office , now it's 23:16 that's time to go to the bed~

  • Moderator

    What firmware version is installed? Can you post the results of M122?

  • @Veti thanks a lot, there is no jumper between them , it work well now.
