Hello dear Cetus community,

I bought a Cetus MK3 half a year ago as my first 3D Printer. It worked perfectly fine and produced nice prints without any fiddling around. I even got the extension board, 24V psu, heated bed and auto probe later, all working fine.

但现在自上周以来，我有一个非常奇怪的问题偏僻！
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 “运动系统错误z“ 错误。我不得不扔掉打印并重新开始。
But I could never finish the print (1-2 hour print time). It always stoped at some point in the print with “运动系统错误z”.
I turned off the printer and wanted to see if I have better luck the next day…

But the next day, things got even worse!
Cetus现在完全发疯了。

I made four short videos to show you the problems.
https://drive.google.com/open?id=1DXwthkaNrwcNpJ_Ox4rljOaURiyutOx3

在视频中，您可以看到以下问题：
-“运动系统错误z” in UpStudio (sometimes I also get “Motion System Error” for X and Y axis as well…)
-“模型出版范围” in UpStudio although its clearly not!
-X轴是crashing in end of axis！！But it only happens sometimes, sometimes not…
-Printer is initializing immediately after turning it on and thendoing random moves......真的很奇怪。

I tried following things but nothing helped:
- 通过USB而不是WiFi连接打印机
- 不同的3D模型/ STL
- upstudio中的“清除缓存文件”+“清除下载模型”
-Checked all motor cables + end stop cables. All Pins OK, reseated all connectors + tested with multimeter. All OK.
- 没有破碎的部件在主板上可见。
-Initializing the printer is working. Motors are moving + end stops react.
- 漫长的延伸板和加热床并使用原始配置。

I don’t know what else to do. I basically can not use the printer anymore at the moment.

我已经开辟了TiVerime支持的票（16546）在7月2日。杰森·吴国只会在初步要求中做出反应，但在我送他的视频之后永远不会回到我的视频，尽管我向他们发送了每天提醒！
@ Jason-TT请回复我的电子邮件或本论坛帖子。我现在感觉有点忽略......
@Cetus-Comunity如果有人有任何想法我可以测试什么，我会很有夸张。

Best Regards

错误：“运动系统错误”

@Mambu, I viewed your videos, and although I have not experienced the same events, I have a few thoughts that may help you.

  1. UPStudio program files might be corrupt on your computer hard-drive, or the temp files UPStudio uses might be corrupt. I would run a diagnostic to check your hard-drive/s files for errors, and also include the check for unused spaces for physical errors. This may correct the errors you see within UPStudio, and also any IO to the printer. I would also check the sd storage card on the printer.

  2. 卸载upstudio并重新安装。确保删除任何临时文件，文件夹和与Upstudio相关的任何内容。

  3. 如果上述任何内容都没有纠正，那么它可能会以某种方式损坏电信号。确保所有电线都远离所有步进电机，所有导线之间存在距离，包括计算机和打印机之间的打印机无关的电线。您也可能关闭除打印机之外的所有电子设备，然后打开打印机并初始化XYZ。

I’ve seen some strange things happen with electronics in my days, from misbehaving microwave ovens 30 feet away messing with electrical signals, photocopier machines 5 feet away messing with the normal use of a computer…electromagnetic interference is everywhere these days!

让我知道事情的事情！

它随机发生在我身上，我向Cetus报道，他们立即发给我两套限位开关和步进电机，因为我的打印机是在保修期间的保修。我还经历了一个层移然后然后是运动错误消息。

While waiting for the kit, I disassembled the Z limit switch and found out it has become loose, which also causes random initialization faults. I checked the X and Y limit switches and they are still ok (no play). I tried to address the Z limit switch issue by putting in a spacer (piece of double adhesive tape) to push the limit switch arm to engage.

ZFix

这样做后，动作错误消失了，套件到达，除了Z限位开关外，我没有更换任何内容。

You did mention that your printer’s initialization always work, but I’d still check the limit switches first.

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.

Mk3 firmware are actually here -https://support.tiertime.com/hc/en-us/articles/360003568353-cetus-rom-update.

@Techsalad.@Arnold非常感谢你的回复和建议s!

@Techsalad.：关于第1和第2点：我没有尝试过，但尽可能在下一个点看到，Upstudio似乎与这个问题没有相关性。
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.
然后我从USB中断开了Cetus并关闭​​了我的电脑。也没有改善。
然后我把Cetus放在我的地下室很远。没有电子产品在那里运行，只有Cetus和房间灯。仍然同样的问题......
Only thing I could try, regarding electromagnetic interference, is to shield the cables with aluminum foil… but this seems a bit silly to me.

@Arnold: I again tripple checked the limit switches. To me they seem to work properly.
If I press them by hand/finger, I hear a “click” sound and if I do it during the homing process, the Cetus immediately stops as he thinks he has reached the end of the axis. So this is working fine.
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.
只有我不确定的东西是，如果初始化过程后Z-Limit开关应始终与线性导轨载滑。在我的打印机上，Z限位开关始终保持“初始化过程”中的“按下”。在x和y轴上，线性轨道滑动在按下后，线路轨道载玻片将远离限制开关。如果这是Cetus的正常行为，我不确定。

I also did the firmware flash.
Cetus connected via USB -> Turn Cetus on -> Reset Functions -> Reset Module -> Cetus ROM Update -> Choose “Cetus S11NTC_R_180524 MK3-EXT.ROM” -> The tool finishes successfully -> Shut Cetus down -> Turn Cetus on -> Same problem:frowning:

Other things I have tried:
Ckecked the SD Card in Windows -> No errors found.
Also tried another 64GB SD Card from my phone -> No difference.
使用原版19V电源并断开了扩展板 - >无差异。

By now I think its some defect on the motherboard or the stepper driver:disappointed_relieved:
Jason-TT：如果您或其他其他支持人员会与我联系以讨论替代方案。我的cetus mk3仍然在保修期之后。

在大多数机器上使用限位开关时，应移动限位开关的对象应该足以脱离并远离开关，就像为您的X和Y一样。在没有限制开关的MKII上，在初始化时，线性导向块始终在击中物理停止后移动一点。

#6

是的，我也这么认为。对不起，我忘记了MK2正在使用不同的方法来设置其限制。
Maybe some other MK3 user can (dis)confirm this behavior?
But if true, the question remains: Why is it not disengaged and how to fix it?

无论如何，Jason Wu终于回应了。他们不知道为什么会发生这种情况，但它们为我提供了主板和CPU的替代品。我希望这将很快解决这个问题:slight_smile:

I got the replacement parts a few days ago.
Had to pay ~40€ for customs and taxes, which I did not expect. But I don’t blame Tiertime for it, they declared the package content perfectly fine. I just somehow thought replacement parts were free from customes in germany：sweat_smile：

但最重要的是，我的cetus再次工作！
首先，我转换了主板，“奇怪的运动”问题立即消失了！
但我仍然有问题在UpStudio告诉我”模型出版范围”. So I reinstalled it, deleted all remaining config files I could find and even installed it on a different notebook. But the error remained.
So I switched also the extension board. This did not changed anything.
Then I switched also the CPU. The new CPU worked as good as the old one (Homing works fine, no strange movements) but it showed a completely wrong nozzle and bed temperature of about 3000°C:open_mouth:So I switched back to the old one.
经过一段时间后，我意识到“超出打印范围”问题，只有发生问题，因为我没有在upstudio中设置“校准高度”：sweat_smile：
如果您没有设置高度，则错误会完全有意义...
在几次重新安装之后，高度值丢失，我从未想过要再次校准它......

So in conclusion:
The new Mainboard fixed the “strange movement” problem.:slightly_smiling_face:
The old extension board and CPU are fine.
The “Model Out of Print Range” problem was my fault. Just remember to calibrate your printer again.

Thanks to@ Jason-TT和Tiertime支持给我发送替换部分！
感谢Techsalad和Arnold试图弄清楚问题。

Happy printing!
