Just finished building this beast. It’s a ratrig Vcore 3.1 with a 500x500x500mm build volume and blazing speed.

    Ayy another vc3500 haver. I use a .6mm bondtech CHT volcano, but honestly I’ve been having trouble getting past 30mm^3 per second, which is unfortunate. My main goal with it is actually giant parts, but the mass production thing is pretty cool too.

      North of ~25mm^3 I’ve found I need to really up the temps to keep up with PLA (mainly using eSun) which then also means a lot more cooling. I managed a pretty decent 14 minute benchy but need to retest as I’ve upgraded my cooling.

      My current setup for extrusion:

      • Rapido high flow with CHT
      • Orbiter 2 with blowy mod to run at higher current
      • CPAP remote cooling with a WS7040 blower
      • HUVUD toolboard on printhead

        Mine is basically the ratrig recommended defaults except for the CHT, a beacon scanner, and a carbon fiber rail. I got to a 16 minute benchy basically immediately, but anything else I print that fast causes either skipped steps or belt slips and I’m not sure why.

          Nice not bad! A pretty easy upgrade for power (if you have a mainboard that supports it) is to go to 48v for the steppers with 5160 step sticks, gobs more power, but you are also now getting to territory where a crash can start really breaking stuff. There is also a group in the discord where they are working on the AWD mod to add 2 more steppers to the XY motion allowing for insane speeds.
