Upgrading my Duplicator i3+ and have a few questions.



  • Got my Duet WiFi this week and finally getting around to attempting to upgrade my old Wanhao Duplicator i3 Plus (technically it's a Power Spec or whatever Microcenters branded version is).

    Everything seems fairly straightforward which is great. I've actually been re-wiring the whole thing while I'm at it. I've been taking some notes along the way and I'll probably post a write-up later as there's not much out there on doing this on the i3+. Right now I'm swapping the board and adding BLTouch, but the ultimate goal is to upgrade further to the ReDuplicator plans and hopefully go from the Microswiss all metal hotend and extruder to maybe a Flexion or something.

    Anywho, I just wanted to clarify a few things.

    1. I've been running the Opticooler for my hot end (similar to Ciii cooler) which uses two 24v blowers. I also ordered a Noctua fan for the extruder cooling (original fan is noisy on startup). That fan is just always on if the machine is on. But the Noctua is 12v. A friend has extra buck down converters. Since my print cooling fans are 24v, I'm assuming I'm best off wiring the buck in between the Noctua fan and the board, correct?

    2. I'm using my existing endstops. They are two wire. I wired them to the outside pins in the 3 pin connector. That's correct right? I am fairly positive I read that but I was trying to find where I read it and I didn't see it again (could have just totally missed it).

    And if anyone has done this same printer and has any tips or just any other tips in general I'd love to hear them. If all goes well with this printer I'll be looking to upgrade my MPCNC board to one of these too!

    Yes you can do that. Use the buck converter to provide the +12v and leave the negative wire of the connected straight through to the fan port so it can be controlled via PWM.

    Yes. https://duet3d.dozuki.com/Wiki/Connecting_endstop_switches#Section_Microswitch
