spool holder with Auto rewind for A1（自动回卷料盘架）

Automatic Rewinding Rotary Spool Holder for A1
带自动回卷功能的A1料盘架

Please exercise patience and peruse this page, thank you
请耐心看完页面，谢谢！

Disclaimer: I own two A1 Minis but not an A1; however, given the similarity in principles, while designing the A1 Mini version, I also created an A1 model. To ensure compatibility, I purchased an external filament spool holder for the A1. Lacking real-world testing, I cannot guarantee this model's efficacy will mirror that of the A1 Mini.

声明：本人有两台A1mini但并没有A1，由于原理类似，所以设计A1 mini版本的模型时顺带把A1的也做了，为此我还专门买了A1的外挂料盘架以便适配，由于无法实机测试所以无法保证该模型拥有在A1 mini上一样的功效。

Special Instructions（特别说明）：

Component appearances may evolve with version updates; images are for illustrative purposes only.

随着版本更新，模型一些部件的外观会随之改变，页面上的图片仅作为参考。

Functionality hinges on filament friction and resilience; therefore, performance may vary with different filaments. The base cover and resistance ring primarily dictate the rewinding angle. The prototype utilized PolyLite (logo color) for printing and testing.
The 6-blade resistance ring typically yields satisfactory results. Appropriate resistance is indicated when the spiral ring on the inner bushing is fully compressed and the resistance ring begins to rotate.
For insufficient resistance, utilize a higher-blade-count resistance ring.
For excessive resistance, trim the resistance blades to reduce friction.
Newly printed components exhibit higher resistance; manual rotation is recommended for a few cycles to achieve operational stability.
Avoid excessively smooth or brittle filament (standard PLA is suitable) for the base cover and resistance ring.
本模型的功能实现依靠耗材丝的摩擦力及回弹力，所以不同耗材打印的模型表现会有一些差异，决定回卷角度的主要配件为基盖和阻力圈，实验模型采用的是PolyLite（标志颜色）进行打印和测试。
默认情况下6叶阻力圈即可实现满意效果，阻力合适的标准表现为转动轴套时，内轴套的螺旋圈基本压缩完全时阻力圈开始转动。
如果阻力过小可以选择打印更多叶片的阻力圈。
如果阻力过大可以剪掉阻力叶片来降低阻力。
新打印的配件阻力相对较大，建议手动转几圈使其磨合到相对稳定的状态后再开始正式使用。
最后建议不要使用过于光滑或者过于脆的耗材丝打印基盖和阻力圈（普通PLA就行）。

Operational Issues（使用问题）:

Impact on Print Quality（是否对打印质量产生影响）:

Extensive testing revealed no discernible impact on print quality. If concerned, manually disable the rewind function during printing.

经过我一段时间的使用和测试，没有发现有明显的影响，至少我没有明显感觉出来。如果你担心这个，在打印时可以手动停用回卷功能。

Extruder Burden（是否会对挤出机带来较大负担）:

Extruders possess significant tension, capable of filament breakage. The added load from this spool holder is negligible (considering the spool radius's torque amplification effect), at least in my testing.

挤出机的拉力是很强大的，甚至能将耗材丝直接拉断，所以回卷架的这点负担应该不成问题（而且还有料盘半径的力矩放大作用存在），至少在我有限的测试中一切都是正常。

Disabling Rewind（停用回卷功能）：
1.Temporary Deactivation: Press your thumb against the shaft cover and pull the claw or threaded bushing outward by 10 mm (a retaining clip prevents slippage)
临时停用，用拇指顶住轴盖，将抓套或螺纹套向外拉出10毫米即可（不用担心滑落，此时还有一层保护卡扣存在）
2.Long-Term Deactivation: Remove the resistance ring for use as a standard spool holder, preventing spool wobble
长期停用，拆除掉阻力圈，即可当做普通料盘架使用，至少料盘不会晃来晃去
3.Permanent Deactivation: Remove all components
永久停用，全部拆掉即可

Adjusting Rewind Angle（调节回卷角度）：
Adjust resistance as described in the special instructions
调整阻力大小即可，见特别说明中的描述
Filament Loading and Replacement（耗材的安装与更换）:
During filament loading, avoid fully inserting the claw or threaded bushing; leave a 10 mm gap (pause mode). Complete insertion after loading eliminates the need for manual filament feeding (due to the rewinding force).

可以直接安装，也可以把爪套或螺纹套取下后安装，另外进料时可以先不把抓套或螺纹套推到底，留10毫米左右距离，即置于暂停模式，等进料完成后再推到底，这样就不需要一直用手推着耗材丝了（因为有回卷力）。

Known Issues（已知问题）：

1.The rewind function produces some noise, considered acceptable.
回卷功能使用中会有一定噪音，但我就觉得在可接受范围内。
2.Over time, resistance diminishes due to smoothing, reducing the rewinding angle.
阻力圈在使用一段时间后阻力会一定程度的变小，因为磨光滑了，回卷角度会缩小。
3.Complete tightening is impossible with low filament remaining (shorter rewind distance due to smaller radius), but this is not detrimental.
在耗材丝剩余不多的情况下，无法完全收紧耗材（因为半径小了回卷距离就短了），但这并没有什么不良影响。
4.Claw bushings may require force for installation on spools at the lower size limit.
各种规格的爪套，安装在其支持尺寸下限的料盘时会比较紧，需要用力才能装入。

Installation Instructions（安装说明）：

Important Note: Prior to installation, insert the central shaft into the inner bushing to assess rotational smoothness. Address any irregularities or apply petroleum jelly to facilitate smooth rotation. Note that warping during central shaft printing can cause binding.

特别注意：在安装开始前，请将中心轴插入内轴套中，测试旋转是否顺滑，如果不顺畅请处理掉不平的地方或抹凡士林使之旋转顺滑（特别注意，打印中心轴时翘边也会造成卡顿）。

Important Note: Step 8 requires rotation to align the bottom retaining clip!

特别提示：第八步需要通过旋转对齐底部的卡扣!
