🎉We can now proudly present the winners of the TAPAS Community Challenge 2018! 🎉
Congratulations to Team "Wireless Charging" (idea 56). We are really excited for all finalists and a really big thank you to all participants for your interest in this challenge!

We got over 200 submissions! 65 ideas got one or more TAPAS boards, 10 submissions were presentation-ready.
And now we have 5 finalists! YEAH 😃 The finalist's idea numbers were 40, 56, 68, 212 and 213.
What's next?
We are now preparing the next steps for you, the community. Please stay tuned!
We are working on a forum and a separate webpage. If you have any question please don't hesitate to contact us via email!


3d printer with magnetic linear motors

Standard FDM 3d printers use belt drives with nema 17 stepper motors. These are prone to errors and slow. Steps can be lost, belt tension can be a problem, resulting in faulty prints, wasted time and material. Direct magnetic linear motor drives eliminate these problems and can achieve significant increase in quality, accuracy and printing speed.

I'm planning to construct a 3-axis dual-extruder 3d printer with magnetic linear motors that could be driven by Tapas boards. I'd need two boards, one for controlling the motors and one for the heat bed and the 2 extruder hot ends.

    Hi Daniel,

    your idea sounds cool!
    Are you sure you include enough TAPAS bards for your idea?
    Our team is wondering if two boards are enough.
    Additionally it would be nice to see a sketch or diagram with the set up.

    Thanks alot :-)

    Hi Nora,

    Thinking about it, no. I came to the conclusion that I'd need 5-6 Tapas boards. Please take a look at the attached rendering.

    Thanks for your feedback!

    Best,

    Daniel

    Hey Daniel,

    thanks for your feedback and interest in the TAPAS community challenge.
    According to the unsureness how many boards are needed and regarding the economics behind we are not sure if your idea fits the criteria of the TAPAS challenge.
    I'm sorry, but your idea can't be considered.

    It is not unsure how many boards are needed. The given numbers are alternatives, it will work with both. It would be more economical to take the lesser number, but then the power output would be split up so the motors would have les momentum. 
    What do you mean with the economics behind? The economic idea behind it is that with magnetic linear motors, you can achieve higher acceleration and deceleration speeds than with belt drives. So the machine can achieve more output in the same time, which is more efficient.
