hey guys sorry for dropping the camera but tomorrow I will be releasing an even faster benchy using a Bowden extruder. print settings: 1200mm/s 175k accel on...

    I’ve seen 247printing’s 3:27 and 2:25 speed benchys (benchies?) on a customized Voron v0, but that fact that someone came in and took the record on an Ender 3 platform is the most impressive thing to me.

      Pushing the boundaries of fast. I love how low qua6the video is so you can tell how excited the person is to get it to print that fast.

      There should be “grades” of Benchy. This speed doesn’t translate to anything you would actually want to print. Aren’t we trying to benchmark the speed of usable prints ?

      Sure I could spit out something like this in 6 min, but in 12 I can make it near perfect.
      I’d call this a fail and tweak my settings

      Make it fast to push the limits of the machine, then bring it back and make it look good afterwards

    Interesting 3D printer design.

    Using 3 linear rails to mount the bed. I suppose each linear carriage is one “corner”/point and all three of them to define a plane without overconstraining the buildplate but you keep all of the rigidity of the linear rails?

    The issue I see is that the three linear rails in one plane are overconstrained so it is still is a pain to setup (especially on an ender 3 like frame construction).

    What is the reasoning for using two motors instead of one powerful in the middle?
