    Thanks for the Shout outs!!! Can't take credit for the new Worm Drive design that was all Rob Mink's work. Oh and the LCD was only $15 shipped as its currently on sale so might still be under $200. ;)

      I have gotten a few of these small printers that used those mini steppers and they fail a lot. Have you thought I about maybe pancake steppers. I’m referring to nant fun k series the extruders shred themselves. I would love to jump on this though.

      @@krypticvoyce I've been working on a Nema14 driven design but at the moment just trying to help make the current hardware work to its best potential. The Primary idea is to keep it inexpensive and upgrading the steppers will definitely hurt the budget.

    Would be great to see a human treadmill conversion project. Maybe with a pellet or clay extruder. They're already built to handle heavy dynamic loads, just need to get fine control of the belt axis, and swap out the (usually wooden) deck plate for a piece of aluminum with a heater pad. And many of them already have the ability to set an incline angle.

    • @VagabondTE
      @VagabondTE 2 года назад +3

      This is exactly what I would want to see out of a printer designed to use recycled plastic. Household plastics were abandoned a long time ago because they reused plastic was too difficult to use and they warped too much. Plus people only wanted speed and detail.
      However, I've always felt we should have gone in the other direction. Big beefy hot ends that can chew through anything. Large diameter filament to compensate for a subpar material. G-Code that compensates for extreme warping. These things are all lying on the table and nobody's even trying.
      Just imagine throwing milk jugs into a shredder at the top of this treadmill pellet 3D printer contraption and it just continually spitting building bricks out the other side. That would be a dream come true for me. And I 1000% believe it's possible.

  • @potatomeatlabs

    Having worked with and used 28BYJ-48 steppers throughout my home automation projects, I don't really understand *why* they need to dwell in this application? That doesn't make sense to me. Is it to prevent overheating? If so, heat management is not that difficult with these, especially with this very low torque application.
    (EDIT: Ignore this point here, it looks like they are already converted to bipolar, as the red wire is not being connected to the main board). Also, it's possible to at least double the produced torque of these steppers by prying off the blue PCB cover and cutting the center trace of the PCB, thus converting it from a unipolar to bipolar motor. I use these to open doors and hatches in my greenhouse, and manage to get over 1 ftlb of torque out of them with a compound gearbox I designed.
    In any case, I feel like the technology used in this project could be leveraged a bit more with just a little more polish/nuance to the design. As it exists, it seems a little haphazard.

  • @mindmending
    @mindmending 2 года назад +3

    That’s a great concept,nice video too. I’d defo try a wider nozzle, treat it like a low res printer. Nema 14s are pretty cheap too, it might be worth spending the few extra bucks on those and using a cheap board, it’s easier to upgrade the board but since the steppers are integrated into the design it would make sense to go with the N14’s, still it’s a cool printer and looks fun👍

    I think maybe the bottom price point goal is too prohibitive. A $350 machine with nema 14s, a screen, real guide bearings, and a slightly better hotend would definitely be worth the cost increase. It's great to see this as I couldn't pop for the cr30 cost!

    • @brianmi40
      @brianmi40 2 года назад

      completely disagree. The simple fact that we have several E3 clones for well under $200 (e.g. Aquila X1 at $159 shipped), means that manufacturing costs are no more than about 50% of that pricing, or in the Aquila instance, about $80, There is no way the components to add a moving bed should cost more than $50, which would yield a total cost of $130, and suggesting a selling price of $260-280 at most.

  • @josephpowell6009

    just thinking outloud ... what if there was a belted printer that printed at 90° (normally) and printed in a interlocking pattern. think wall bricks being laid with a shallow stairstep leading edge.
    it would be software intensive and need considerable Y (or belt Z) travel , quick clearance on 1 side of the nozzle , and it would have brick-like seems , but i think the would solve the layer-line weakness of current long parts. plus the regular benefits of a normal printer.

    This is a great idea. If all you want to print is things like table legs or swords, a small X and Y are fine. That lace-like pattern really looks like under-extrusion. I'd try some glue-stick to reduce the amount that PLA is sticking to the belt.

  • @Karavusk
    @Karavusk 2 года назад

    I wonder if you could use a relatively stiff belt material and put kapton tape on it. I guess it probably just comes off after a while. Also the printer was probably just running klipper so you can either edit the config file on the raspberry pi to change the offset permanently or just enter the command in the terminal.

    Wow! Good thinkering direction for an infinite z but instead of printing on a cold slack rubber-ish belt, is there any metal tambour-style track conveyor?
    A succession of carefully positionned nice flat surfaces about ½-1" to print on. Heat only the first ones and the part could pop off when it's cool at the end. Or the heat at the end, to a blade that shaves the part off smoothly, like the Autoejection Polar!
    I'll drop my Monoprice Select Mini in the stairway and fit all that in an old router table... I'll need a Discord account too!

    As an aside, the chip shortage isn't so much to do with China, as China currently only produces 18% of the world's semiconductors (just a little more than the US). It's really a global problem, but Taiwan makes 60% of the world's chips (by value) and just one company there, TSMC, makes about 90% of the leading edge chips.

I've modified it to work perfectly because of new filaments such metal suspension in pla . Its awesome and you can put in a kilen and come back with 100% metal part. I think that's dope especially since I'm making crazy that requires all possibilities. There is only yes we never no we can't.

    Although unlimited length objects is flashy, it seems to me not nearly as useful or practical as it's made out to be. It comes at the expense of quality with these 45-degree print lines. Why not a vertical Z that builds one part at a time and ejects it. Following that logic, why not a special belt bed I can mount to my existing printer which allows me to eject parts. It seems like too many parts to put a printer on top of the belt mechanism when it could be a bed feature clipped and plugged into an existing printer. ??

    • @NAK3DDesigns
      @NAK3DDesigns 2 года назад +1

      that type of belted feature can't be done because it is protected by a Makerbot patent, this is why all current belt printers use the 45 degree axis approach as it isn't covered by the patent.

    In my opinion, it seems like you're misdiagnosing a few of these problems... the multi-second pause is not the motors, it's the software (possibly being held back by the MCU), for advanced kinematics like this you really need a 32-bit MCU. Also, the spotty infill is much more likely to be caused by the extruder not pushing the plastic evenly and consistently...

    I find the cr30 printer pointless. They used their bottom basement extruder and screen and built a 1500cad paper weight. Unless I'm wrong. That little printer puts creality to shame in so many ways. Good work. I love the little steppers, I have a bunch of them and drive them with the uln2003 darlington transistor ic. Those steppers all behave differently as well. I made the wife a carousel clock and I had to change the motor and tweak the code a bunch.
