由于拓竹AMS不支持TPU耗材，而TPU耗材又极易受潮，因此需要存放于独立的干燥盒内，并且由于TPU耗材具有高弹的特性，在拉长到一定长度后线径会变细，导致挤出机齿轮无法很好咬合料线，底部滚轴式的料盘架存在料盘过重，挤出机无法咬住变细的料线来拉动料盘，导致无法顺利出料，打印失败的问题。

本料盘架设计了一个可分离的手柄结构，通过将轴轮钩挂于手柄上，可轻松将料盘从狭窄的米桶干燥盒内取出，提升了更换料盘的便利性。手柄和底座的结合位置均设计了导槽结构，方便迅速对位。

*本料盘架需自行购置2枚标准608ZZ轴承。

*本料盘架长宽高尺寸为：223mm x 100mm x 217mm，兼容市面上的5.8L米桶。

*安装时建议在轴轮的轴杆两端先用生料带缠几圈再装上轴承，避免在更换料盘时轴承从轴杆上脱落。

*考虑到不同耗材的收缩率不同，为了便于安装，各安装孔截面非圆形，对于多数低收缩率的常规耗材如PLA、PLA-CF打印的成品存在松旷现象，建议安装到位后使用瞬干胶进行粘接固定。此预留公差主要考虑如果存在旷量，可以通过点胶进行组合，但如果孔洞收缩率过高导致手柄无法插入，将会造成零件的报废和时间的浪费

2024.03.03更新，缩小料盘架基座宽度，以适配更多市售5.8L米桶

Because the AMS does not support TPU filaments, and TPU filaments are very susceptible to moisture, they need to be stored in an independent drying box, and because TPU filaments have high elastic characteristics, After being elongated to a certain length, the wire diameter will become thinner, resulting in the extruder gear can not bite the material line well, and the bottom roller type tray rack has the material tray is too heavy, and the extruder can not bite the tapered material line to pull the material tray, resulting in the problem of unable to discharge smoothly and printing failure.

The tray holder is designed with a detachable handle structure, and by hanging the axle wheel hook on the handle, the tray can be easily removed from the narrow rice bucket drying box, which improves the convenience of changing the tray. The joint position of the handle and the base is designed with a guide trough structure, which is convenient for quick alignment.

*This tray frame needs to purchase 2 standard 608ZZ bearings.

*The length, width and height dimensions of this tray rack are: 223mm x 100mm x 217mm, compatible with 5.8L rice barrels on the market.

*When installing, it is recommended to wrap the two ends of the axle wheel with PTFE sealing tape several times before installing the bearing, so as to avoid the bearing falling off the shaft rod when replacing the tray.

*Considering the different shrinkage rates of different consumables, in order to facilitate installation, the cross-section of each mounting hole is not circular, and there may be loose phenomenon, so it is recommended to use super glue for bonding and fixing after installation in place. This kind of reserved tolerance is mainly because if there is a gap in the assembled part, it can be combined by glue, but if the hole shrinkage is too high for the handle to be inserted, it will resulting in the scrapping of the handle parts and wasting your printing time.
