    • RE: Duet not respondng, 3.3v LED is off

      @T3P3Tony:

      The DuetWifi generates 3.3V on board from 5V, supplied by USB, external 5v or from the VIN supply though another convertor. If you have no 3.3V light with USB plugged in with a board that was previously working the first point is to try it without endstops and other inputs connected and then can short 3.3V to ground if they have an issue

      As I said, I tried it to the point without anything connected. The endstops were the first stops as this was one of the solutions that I found on the internet but it's not working. The board worked fine and when the print was over and everything cooled down, I turned the printer off and went to re-connect it to the new wifi. Now I can't do anything.

    • Duet not respondng, 3.3v LED is off

      Hi people,

      Yesterday a new router arrived and so i plugged the USB (it was running only on usb power) to connect the duet to the new router . Plugged the board in and I got a error saying that the USB device has malfunctioned. I unplugged it and plugged it back in and this time I didn't even get a response from the PC but I noticed that the 3.3v LED is off. I unplugged everything from the board but it's still unresponsive. What can be done?

      Thank you all in advance.

    • RE: Fan stopped working mid print, Always on is burned now.

      Well I soldered it and it works like a charm now. Thank you so much for your help. Have a nice day, I hope it's sunny in the UK as it is in Ireland today 🙂

    • RE: Fan stopped working mid print, Always on is burned now.

      Hi dc42,

      Thank you for the reply.

      Indeed it is burned on the ground pin. But what caused it I can't explain as the fan that was used is still working normally and there was no possibility of a shortage (i took extra care when I wired everything to the board). Unless there is something wrong with the electronics of the fan itself that might have caused this, guess I'll never know. Anyhow I checked the resistance and the multi-meter doesn't even react when I check the resistance between these two points, so I guess that the resistance is below the measurement capability of my multi-meter (it's a cheap Chinese one). Now before I start soldering (I never did a PCB bypass before) can you confirm that these are the correct pins to put a wire on? I don't want to fry the board 🙂

    • Fan stopped working mid print, Always on is burned now.

      Hello people.

      Yesterday I was printing something and in the mid of the print i just heard a weird "pop" and the fan that is connected to always on stopped working. I paused the print, turned the printer off and went to inspect. I noticed that there is a black spot under one of the connectors on the board for the fan. This was the only fan connected and after I checked the board I couldn't find any burned components besides the one mentioned. Today I checked the connectors with a Voltmeter and at first it showed 11.5V on the always on fans and PWM fans voltage changed normally as I changed the speed of the fan in the DWC. I checked if the printer is working and everything is fine except for all the fan ports. Then I checked again and it displayed around 6v on each of the connectors. When I connect a fan to any pins it's not working. Can somebody please help me, the board is about a month old and it's not really useful without the fans. Here are a few pics, sorry for the bad quality, I took them with a cheap endoscope camera

    • Add plus and minus buttons for temperature, speed and extrusion.

      Hello people.

      I love the duet wifi and once I got it up and running properly (finally) I started to notice a few things that are missing in the web interface and I would love for them to be there. The thing I would like to see the most would be simple plus and minus buttons for increasing/decreasing temperature and the same for speed and extrusion. This would be very useful on the temperatures because you can adjust it on the fly without the need to go into the system properties and add temperatures to the list (this is kind of limiting as you have to add a new temperature every time you want to experiment). These would also be neat on the speed and extrusion sliders so that you can fine tune.

    • Duet Wifi extrusion nightmares.

      Hi guys.

      I bought the board about 3 weeks ago and I still can't get a normal print from day 1 whatever I do. Everything is calibrated and tested with a caliper so steps per mm are alright. Here is a pic of my lats print. It started normally but then it made the first layer of infill which went fine and the second infill layer started with the inconsistency and then it started doing the top layer and did this mess. Mechanically everything is the same as with the previous board and I copied the extruder settings from marlin (it printed flawlessly on the previous board).
      The setup is a E3D V6 original with MK8 all metal extruder. These symptoms appear no matter the speed or the settings, it's like the board is handling the extrusion with a mind of it's own, regardless of my settings.

      Here are some pics:

    • RE: Duet Wifi, PSU, Mosfet and bed level probe

      Thank you for the answer. Excellent, so I can even use the second set of wires for something on the side like LED's or something. Thank you very much.

    • Duet Wifi, PSU, Mosfet and bed level probe

      Hi Guys,

      I had quite a lot of issues with previous boards and my DuetWifi came today (that is what I call proper packaging, give the packer a raise) and my current configuration is such: GT2560 board that has a 4pin connector (2x V+ and 2x V-) and one of those heatbed Mosfets that is connected to the 3rd set of V+V- on the PSU. Do I have to just connect the two sets of wires from the PSU together and plug them into the VIN on the Duet or should I just use one and leave the other one intact? The mosfet is connected to the heatbed control as normal.

      Another thing: I have a proximity level probe (https://www.amazon.co.uk/gp/product/B00542U3M4/ref=oh_aui_detailpage_o06_s00?ie=UTF8&psc=1) and it's wired so that the brown one goes directly to the 12v power and the rest goes to the endstop. Can I wire it the same way or do I need some voltage regulator or something?
