你好亲爱的Cetus社区，亚博国际网页登录平台

我在一年一年前买了一个Cetus MK3半作为我的第一个3D打印机。它完全良好，并产生了漂亮的印刷品，没有任何摆弄。我甚至稍后获得了延长板，24V PSU，加热床和自动探头，所有工作都很好。

But now since last week I got some very strange problems out of nowhere!
It started with the Cetus making random “beep” sounds from time to time. Later that day Cetus just stops in the middle of the print, drives the z axis to the top and stops. I could not resume the print and UpStudio shows me a “Motion System Error Z” error. I had to throw away the print and start again.
但我永远不会完成打印（1-2小时打印时间）。它总是在印刷的某些时候停止“Motion System Error Z“。
我关掉了打印机，并希望看到第二天我有更好的运气......

但是第二天，事情变得更糟！
The Cetus went completely mad now.

我做了四个短视频来向你展示问题。
https://drive.google.com/open?id=1dxwthkanrwcnpj_ox4rljoauriyutox3.

In the video you can see following problems:
- “Motion System Error Z“在Upstudio（有时我也为x和y轴获得”运动系统错误“......）
- “Model Out of Print Range“在upstudio虽然它显然不是！
-X axis iscrashing in end of axis！！但它只发生在有时，有时候不是......
-Printer is initializing immediately after turning it on and then随机移动… Really strange.

I tried following things but nothing helped:
-Connecting printer via USB instead of WiFi
-Tried different 3D models/STL
- “Clear Cache file” + “Clear downloaded models” in UPStudio
- 检查所有电机电缆+端部停止电缆。所有引脚OK，重新安装了所有连接器+用万用表测试。一切都好。
-No broken parts visible on mainboard.
-Initializing打印机正在运行。电机正在移动+结束停止反应。
-Removed the extension board and heated bed and used the original configuration.

我不知道还有什么可做的。我此刻基本上无法使用打印机。

I already have opend a ticket for Tiertime Support (16546) on Jul 2. Jason Wu only reacted once to the inital request but never came back to me after I sent him the videos, although I send daily reminders to them!
@Jason-TTPlease respond to my emails or this forum post. I’m feeling a bit ignored right now…
@Cetus-ComunityIf somebody here has any idea what else I could test, I would much appriciate it.

最好的祝福

Error: "Motion system error"

@mambu.我看了你的视频，虽然我没有经历过同样的事件，但我有一些可能对你有帮助的想法。

  1. Upstudio程序文件可能会损坏计算机硬盘驱动器，或者upstudio使用的临时文件可能已损坏。我会运行一个诊断来检查硬盘驱动器/ s文件是否存在错误，并包括检查对物理错误的未使用空间。这可能纠正upstudio内看到的错误，以及打印机的任何IO。我还将检查打印机上的SD存储卡。

  2. Uninstall UPStudio and re-install. Make sure to delete any temp files, the folders and anything related to UPStudio.

  3. If the above does not correct anything then, it could be that electrical signals are becoming corrupted somehow. Make sure all wires are rerouted away from all the stepper motors, and there is distance between all wires, including the wires not related to the printer in between your computer and the printer. You might also turn-off all electronics devices except for the printer and then turn on the printer and initialize the xyz.

我已经看到了一些奇怪的事情发生在我的日子里的电子产品，从错误的微波炉30英尺远离电气信号，复印机5英尺远离电脑的正常使用...电磁干扰到目前为止都在无处不在！

Let me know how things go!

It randomly happened to me, I reported it to Cetus and they immediately sent me two sets of limit switches and stepper motors as my printer is under warranty. I also experienced a layer shift and then followed by the motion error message.

在等待套件时，我拆解了Z限位开关，发现它变得松动，这也导致随机初始化故障。我检查了x和y限制开关，它们仍然可以（没有播放）。我试图通过放入间隔件（双胶带）来推动Z限位开关问题来推动极限开关臂接合。

After doing this, the motion error went away, the kit arrived and I didn’t replace anything except the Z limit switch.

您确实提到您的打印机的初始化始终工作，但我仍然先检查限位开关。

[edit]

You did mention that you checked the limit switches, and based on your video, we can take UP Studio out of the equation. You’re using the hardware initialize switch and it still behaves that way. It looks to me like corrupted firmware, or worse malfunctioning stepper motor drivers. If it’s firmware, ask Jason for the Mk3 firmware and flash it again.

PS。

@techsalad@Arnold非常感谢你的回复和建议s!

@techsalad: Regarding point 1 and 2: I did not try this yet but as you can see in the next point, UpStudio seems not to be of relevance for this issue.
Point 3: I did try to route all wires away from the stepper motors (mainly the Z motor) and to have space in between them. It did not help.
Then I disconnected the Cetus from the USB and shut down my computer. Also no improvement.
Then I placed the Cetus far away in my basement. There is no electronics running there, only the Cetus and the room lights. Still the same issue…
对于电磁干扰，我唯一可以尝试的是用铝箔屏蔽电缆......但这对我来说似乎有点愚蠢。

@Arnold: I again tripple checked the limit switches. To me they seem to work properly.
如果我用手/手指按下它们，我会听到“点击”声音，如果我在归位过程中这样做，那么Cetus立即停止，因为他认为他已经到达了轴的末端。所以这是正常工作。
Also unscrewed the Z limit switch holder (the end cap) from the Z axis. There is no loose screw inside. The limit switch stays firmly in place.
唯一我知道的是,如果Z-Limit瑞士tch should always be in touch with the linear rails slide after the initialize process. On my printer the Z limit switch always stays “pressed” after the initialize process. On the X and Y axis the linear rail slide moves a bit away from the limit switches after it was pressed. I’m not sure anymore if this was the normal behavior for Cetus.

我也做了固件闪光灯。
Cetus通过USB连接 - >转动Cetus On - >重置功能 - >重置模块 - > Cetus ROM更新 - >选择“Cetus S11NTC_R_180524 MK3-Ext.ROM” - >工具成功完成 - >关闭Cetus Down - >转为Cetus On- >同样的问题：皱眉：

Other things I have tried:
CKECKED Windows中的SD卡 - >找不到错误。
还尝试了另外64GB的SD卡从我的手机 - >没有区别。
Used the original 19V power supply and disconnected the extension board -> No difference.

By now I think its some defect on the motherboard or the stepper driver：令人失望的是：
Jason-TT.: Would much appriciate if you or some other Support staff would get in touch with me to discuss a replacement. My Cetus MK3 is still under warranty after all.

＃5

On most machines using limit switches, the object that engages the limit switch should be moved enough to disengage and move away from the switch like it does for your x and y. On the MKII without limit switches, when initializing, the linear guide blocks always move a bit after hitting the physical stops.

＃6

Yes, I also think so. Sorry, I forgot that the MK2 is using a different method to set its limits.
也许其他一些MK3用户可以（DIS）确认此行为？
但是，如果是真，问题仍然存在：为什么它没有脱离和如何解决它？

Anyhow, Jason Wu finally responded. They have no idea why this is happening but they offer me a replacement for the mainboard and cpu. I hope this will fix the issue very soon：least_smile：

几天前我收到了更换部分。
必须支付〜40欧元的海关和税款，我没想到。但我不责怪TiVertime，他们宣布包装内容完全罚款。我只是以某种方式思考替代零件免于德国的习惯:sweat_smile:

But most importantly, my Cetus is working again!
First I switched the motherboard and the “strange movement” problem was gone immediately!
但我仍然在Upstudio中发出了这个问题，告诉我“模型出版范围”。所以我重新安装了它，删除了我可以找到的所有剩余配置文件，甚至在不同的笔记本上安装它。但错误仍然存​​在。
所以我也转换了扩展板。这没有改变任何东西。
然后我也切换了CPU。新的CPU与旧的CPU一样好（归巢效果很好，没有奇怪的运动），但它显示出完全错误的喷嘴和床温约3000°C：张开嘴：所以我转回了旧的。
After some time I realised the “Model Out of Print Range” problem only occurs because I had not set the “calibration height” in UpStudio:sweat_smile:
The error makes totally sense if you have not set the height at all…
After the several reinstallations the height value was lost and I never thought about to calibrate it again…

So in conclusion:
新的主板固定了“奇怪的运动”问题。：sife_smiling_face：
旧的扩展板和CPU很好。
“型号出版范围”问题是我的错。请记住再次校准打印机。

Thanks to@Jason-TTand Tiertime support for sending me the replacement parts!
And thanks to techsalad and Arnold for trying to figure the problem out.

快乐的印花！
