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?

    As you have separate wires from your PSU to the bed heater mosfet, one pair of wires to the Duet will be adequate.



  • 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.
