Ultracube

This project is still in its early stages, but it's shaping up to be an upgraded version of the Hypercube Evolution with linear rails for X and Y axes, supported by a sturdy milled aluminum gantry. The design takes on an H-BOT layout instead of a Corexy configuration, despite knowing that H-bot suffers from racking when moving along the x-axis. However, at lower acceleration rates, this issue becomes almost imperceptible due to its small size. It's worth noting that it may be possible to convert this design into a CoreXY with additional components such as idler holders and an x-carriage, which could potentially allow for the use of a thinner plate (3.175mm) instead of the current 6.35mm plate used in the X-gantry. The gantry plate is specifically designed to fit within a 300x200 or 300x300 Hypercube Evolution frame calculated using Scott's original spreadsheet. The x-carriage can be set up either as a direct drive or bowden-style extruder by simply attaching the motor to the frame rather than mounting it on top of the carriage. I personally prefer the direct-drive mode because it should provide better performance for prints with many small islands, significantly reducing the chance of clogging the heatbreak. This setup also allows you to use up to the last few centimeters of filament, unlike leaving about 1 meter behind due to the extruder gear's inability to grip it. The build platform base has been simplified and made easier to align by adopting a single-Z configuration for now.

Note: This design has been scaled down to create a printer with a smaller build volume (150x100x120), which is fully functional and produces superb print quality.
