其他必需的组件：
升级后，如果用户安装加热的构建平台，则原始电源不能用于为机器供电。用户必须使用220W电源（SKU：XS028）。
Step 1. Print Plastic Parts Required for Upgrade
Before dissasembling everything, printer out the parts required.
Download the following file for the printable parts:
Step 2. Dissamble the Machine.
2.1。通过删除3个ScERWS删除平台。
2.2 Remove the 4 screws to the bottom of machine.
2.3. Remove the power cable and the initialization button cable.
2.4. Remove CPU. Before remove the CPU, discharging yourself is recommended, also be careful not to bend the pin of the CPU board.
2.5. Remove the SD card on mainboard.
2.6。卸下主板上的4个螺钉，请拔下挤出机电缆，电机电缆，卸下主板。
Step 3. Install MK3 Mainboard.
3.1 Remove brass nuts by hand
3.2 Install the Mainboard Adaptor and MK3 Mainboard.
3.3. Install MK3 Mainboard, CPU and SD card.
3.4. Connect Ground Cable (reduce risk of static charge damage to electronics)
Step 4. Install Y-axis Limit Switch and Trigger.
4.1。拆下螺丝
暴露原来的y触发器
4.2。损坏带背面的螺钉，取下印刷部分。Do not remove the screw from the belt, keep it on the belt!
4.3. Install the New Y Limit Switch Trigger
步骤5.安装Y轴限制开关
5.1. Install the limit switch on the holder.
5.2. Remove the original printed part and the screw on the motor.
5.3. Install limit switch holder onto the Y-axis motor.
Step 6. Install the X-axis Limit Switch
X轴限制开关支架
6.1 Open the slot cover on the back of the printer.
6.2将持有者按到插槽中，安装限位开关。
6.3将电机电缆放置到槽中的开关电缆并按压槽盖。
Step 7. Install Extension PCB

Detailed Guidance on Extension Board Installation and Limited Switch Issues
7.1 Uninstall the Z-cap
7.2 Slide the extension board into extrusion slot.
步骤8.安装MK3 Z轴盖和限位开关。
8.2安装Z轴限制开关。
步骤9.连接电缆
9.1 Connec Z-limit switch and Y-limit switch to the extension board. Follow the color.
9.2使用附带的继电器电缆将极限开关从分机PCB连接到主板。
9.3将电源线从分机PCB连接到主板
9.4松开连接器（标有“平台加热器”，用于带状电缆。将电缆插入连接器，金属销面向主板。
9.5电缆折叠成形状像the red line indicated below.
9.6通过电机和Z轴支架之间的空间插入带状电缆。
9.7 Fold the cable upward and insert into the connector, metal pins facing toward extension board.
This ribbon cable is important for temprature control of heated bed upgrade and autoleveling.
步骤10.安装WiFi天线
10.1 Insert the antenna holder into the slot of the back of machine, turn it 90 degrees to lock it in position.
10.2 Insert the antenna into the holder and connect the other end to CPU.
10.3 Make sure the cables are well sorted, no tangling. Install the PCB cover.
10.4. Lock the PCB cover.
10.5. Lock the extruder cable along the Z-axis
STEP11。ROM更新：
必须在机器使用前更新CPU ROM，请参阅以下信息以更新您的ROM。

Can the mk1 use this kit too?
我有问题安装升级：套件中的项目5和7的物品不同于上面的规格;接地线是不同的（没有5路插头连接到PCB），如果黄铜支架安装在主板适配器上，则USB /电源插座不会与孔对齐，如上所示 - 它看起来像电路板需要直接安装到适配器，或者需要将支架移动到底板中的新钻孔和螺纹孔，并且适配器丢弃。我将提交支持请求 - 不确定是否监视了这些评论。
Will Tiertime issue signed drivers for Windows?
I have completed the hardware upgrade, but now can't upgrade the ROM, as Windows does not have the correct drivers. I tried downloading the drivers from the website, but these are still not signed and so will not install.
关闭寡妇安全功能以强制安装不是一个理想的解决方案。
嗨套件有不同的错误：
1. the 3d printed parts are not ok
https://support.tiertime.com/hc/article_attachments/360042023454/pgrade_parts.up3.
对于Z轴，我必须使用原来的帽子为endStop制作一个孔，因为来自我的打印机的线性导轨似乎更短（黑色部分是从上面的链接中的新增功能（不适合）。
安装主板时，它太靠近底板边缘，使得我不能再次将盖子放回。因此，我在底板上钻4个孔，将主板转移到中间约5毫米。
安装所有硬件后，我将闪烁CPU

seems to work...but.... the hardware Init switch did not work anymore !!!!!!
Init via software is working and the endstops are working too.
But thats not all !!!
当我Wistetd第一次打印时（当然当然）喷嘴首先清除（一条直线），即确定。但是，当启动第一个筏层线时，喷嘴似乎挖掘了打印床。
Y和Z轴同时移动。

So I dont know whats wrong and I need support
我对基础封面有同样的问题。这是唯一的解决方案吗？印刷很好。
It works for me:主板适配器板（REMIX）
And: I mounted the board directly on the adapter.
It seems that they forgot to remove the v-groove edge rails from the PCB. After removing them carefully with pliers the PCB fits perfectly in the case with the original adaptor.
i cant get anything to work after Rom flashing attempt. It only took 1 second so I don't think it flashed the new firmware. Anybody?
I have the Problem, that after flashing the rom, connecting the momentary switches and doing evrything above (plus the adjustments in the coments), the printer just ignores them and jamms right in the z-Axis stopper. In the Up studio software there is an system error, after reinstalling the rom using the utility software that error was gone. Problem is still there. please Help
