Duet with a small printer



  • This is gonna be kind of an odd question…What's the smallest printer you guys have got a Duet cleanly mounted to (a separate control box is ok)?

    For background, I'm finishing up a HEVO, and I'm starting to consider my next printer project, and I'm wanting to do as tiny a printer as possible for printing miniatures, dedicate it with 0.9 steppers and a .2 nozzle, stuff like that. Intentionally keeping the build area somewhere around 100mm^3 or roughly equivalent in delta (call it 110mm diameter or so) if possible, just to keep myself from overloading the bed with that tiny nozzle. Aiming for precision over speed. And I'm aware by the time I'm done, I could have just gotten a small resin printer for similar or better results, this is to try and satisfy curiosity.

    For example, I'm looking at this https://www.thingiverse.com/thing:436281 and https://www.thingiverse.com/thing:360414 but I'm not sure how well I could integrate the Duet on that Delta and keep it looking good like that.

    So I'm curious if any of you guys have tried going for a small build with a Duet.



  • Have you considered using a resin printer? There are some nice projects, using ipad Retina screens, and daylight resins. This is a good alternative for small and detailed parts.



  • I'm in the middle of finishing up small build printer volume 118x118mm.

    For small detailed print ither than obviously small nozzle, you must also have removeable bed and dual extrusion capable of PVA support

    The main constraint with a small delta with conventional belt drive is that there isn't room to mount the Duet between the stepper motors. If the stepper motors are at the top as in that design, you could mount it just above the motors, at the cost of a little more overall height. Alternatively, you could mount it just below the top of the frame, then you wouldn't need to increase the height.

    I have. One, it keeps my supply line simple because I already have one FDM printer. Two, I basically already know the tech (I'll have to learn delta geometry if i go that route but not a big deal). And most importantly, 3, I want to build it myself. At the minimum a kit, or from scratch if necessary. And I'm not happy with the resin printers I've seen so far.

    This is what I was kind of thinking. Height doesn't bug me so much, I just would rather not have a rat's nest of cable running out over to a control box. Simple to disconnect and move if necessary.

    I'm satisfied enough with my S3D support settings that a dual extruder is overkill, though I wouldn't rule one out. Especially because I'm thinking Zesty Nimble for the extruder anyway. And I as thinking Buildtak flex sheet for the bed, I've always had good success with it so far. Any build info on your printer? That is right in the size category I want.
