Panel due and sensor

  • Ok I have managed quite well in getting all connections and stuff put together, I have uploaded a config file with all the required data from my older duet. I have however come across a couple of issues which I'm thinking is my fault anyway, 1st is that anytime the printer is turned on the panel due continually says connecting in the top right corner but never does, I have checked and triple checked the wiring diagram and everything seems to be right, that leads me to my second issue as that it is the same for the z sensor, this agin is wired in as described on the diagram but the web OS does not pick it up at all and the panel due does not connect. Lastly when ever I try to home the printer the motors just go nuts and don't actually home at all. I'm now just scratching my head of what to do.

    The panel is wired up as follows, red to vin, black to gnd, blue is to urxdo and green to utxdo.
    Sensor is set to red to 3.3v, black to gnd and green to z probe in
    Lastly motors are plugged in as follows, rear tower to z, left to x and y to right

    I'm now tearing my hair out of what to do

    Hopefully someone may be able to point out any mistakes I may have made

  • I'll preface my comment with the fact that I'm a relative noob in the 3D printing world. I haven't used the dc42 firmware yet either, but I have been doing a whole lot of reading before hooking things up.

    It also would be good to know what type your printer is and what mods you have done to it.

    Can't really help with the Panel due or the sensor, but the motor stuff is possibly easier.

    Don't know if you've seen this yet, but it looks to be pretty helpful.

    Here's a good test from the above blog to see if the motors are set up right:

    Send G91 to select relative mode. Then test the motors individually by using the G1 command with the S2 parameter. Be ready to hit the power switch if anything goes wrong. First, send G1 S2 X10 F500. This should cause the X carriage to go slowly up 10mm and stop. Changing the parameter to X-10 should make it go down 10mm. Similarly, test the Y and Z motors by using Y10, Y-10, Z10 and Z-10 in place of X10.

    You probably want to go back to absolute mode after doing this, or maybe just reset the Duet.

    Some other links I've put together in preparation are these:

  • It's a delta printer to start and it has been working prior to installing the upgraded board just a lil stuck now

    Rommie, please can you post photos showing how the PanelDue cable is connected, at both ends. Also check that you have the PanelDue and Z probe cables connected to the correct connectors on the Duet WiFi, since the connectors for those two ports are of the same type.

  • will drop the pics up a bit later today when im home, I was thinking it may be that the TX and RX are the incorrect way round, I was going to try that a bit later also. As for the sensor I had it on a duet 0.6 prior as such it was split into 2 connectors so I installed it to a 4 pin Molex and have it powered just no response from it on the web interface. im not sure I have the signal in the correct pin, currently signal pin goes to z_probe_in.

    I will also link the config file just in case I have made a boo boo there but I cant see any mistakes as yet

    thanks for the reply DC

    The order of the PanelDue wire colours should be the same at both ends of the PanelDue cable, which if you are using the standard colours will be red-black-blue-green. If you are using Molex connectors at both ends, they will be reversed with respect to the tongue position. The Z probe out wire goes to one of the end pins of the Z probe connector.

    Here is a photo of my PanelDue and Z probe wiring. My PanelDue cable uses a white wire in place of a blue one.

  • ok my headers had somehow got changed so got the panel working now, although I have chased the sensor up and still having a hard time with that, it is set out the exact same way as in your picture, and still having an issue with the motors too

    just hoping I'm not missing anything on there motor wise

  • woooohoooo its fixed

    woooohoooo its fixed

    Glad you got it working! A couple of questions:

    1. What fixed it? (in case it helps other people)

    2. When you say "the headers got mixed up", can you confirm that you don't mean the board was manufactured with the connectors fitted the wrong way round?

  • Hi dc,

    In terms of the panel due the d in and D out where the wrong way round on the panel due side of my wiring so as per your picture above your white wire was my green and vice versa, that solved the panel issue. As for the motors going mad I noticed whilst moving some of the wires that 2 had completely sheared at the top of the molex on the z motor, just a quick install of 2 new crimps and that sorted that issue. Lastly for the ir sensor I have no idea what or how that got fixed but after the motors were sorted it just worked.

    I think maybe when I have been installing the duet I have caught and caused the crimps to break and just did not notice it till earlier on, will teach me to check , check and check again

  • The duet board itself for the panel due and ir sensor plugs is perfect and no issues from manufacture
