COMMENTS WELCOME
This is a printer I've been designing, which I've borrowed a couple things from the Hyper Cube Evolution. This will probably take a long time to gather the parts together, due to price, but I have some parts already. Things that are missing is a part cooler and which board to use.
More info:
Design Goals:
Minimum maxium speed of 100 mm/s (150 mm/s would be great, 300 would be awesome) with decent precission and accuracy.
350x350x500 build volume.
Extra space to make sure the carriage completly clears the bed.
100 Micron resolution
Features:
Core XY kinematics.
3030 based frame.
6mm thick aluminum bed24V 350x350 mm silicone heater (300-325W)
120V 350x350 mm silicone heaterPolyurethane Steel Core 2GT belts.
Easier A&B belt tensioning (stolen from the Hyper Cube Evolution project).
Hiwin linear rails, becuase round rods and the bearings are not that great.
Proper bearings, meaning that toothed bearing should be used when the tooth side is against a bearing.
Boden setup, less weight on the XY = more speed.
Real E3D hotend, less issues with filament jamming.Olsson Ruby nozzle, print a wider range of filament with out having to replace.
32-bit controller, faster processing with better precision.
Designed for higher amperage 12V setup, but use a 24V supply. Lets keeps the fires out of this.
Solid state relay for hotbed. Just because we can and, well, less fires.
Better wiring:
GX12-6 Connectors.
