想問台灣哪裡有賣不錯的雷射切割材料（很薄的MDF 全黑的很薄的壓克力板等等）。我的Mr Beam II要來了。

因為Atom也可以雷射雕刻，而且之前看過這裡有人分享Mr Beam II，所以想說可能有人會懂。

第一張圖是我找到的大範圍列印校正教學的lcd選項，
第二張是我自己的lcd選項，是不是版本不同還是有別的問題，我找不到教學中的校正選項，還請各位幫幫忙了～

所以你要校正？就bed leveling阿！裡頭有Auto leveling吧！

李安軒
2017-05-22 11:58:43

https://youtu.be/DrYVG0NEhRI 我是看這篇要做更近一步的校正，因為大面積的列印一直失敗

Dennis Chen

那個是大大拿新的marlin去改的...我也很想要有這個功能的說，ATOM預設的firmware太舊的

李安軒

原來如此～原來是高手的方法，那我只好先Auto Leceling繼續試試了謝謝大家喔

Am I wrong?

This photo shows why I think large multi-filament prints done with multi-extruder/single nozzle outputs always end up with a clogged hotend. The reason is that when the current extruder retracts filament to make way for next extruder to feed the next filament, there will always be a string of filament left behind in the hotend.

This photo shows what I found after disassembling my hotend so I could install a new one. I had recently finished a print, and when it finished I manually pulled the filament back from the hotend about 20 cm. I did this so I could take the hotend completely apart. After I got it apart I manually pushed the filament forward so I could see what the end looked like. The photo shows what I found.

Note that there is a long string of filament extending pretty far from the end of the filament. So it seems logical that there would be some bits of filament left behind inside the hotend after any retraction, and this is what I feel results in a buildup sufficient to clog the nozzle during a long print job.

I am most interested in hearing other opinions on this. Thanks in advance.

I used to have long string too, after I made some adjustments to push the PTFE in hotend fimed, the string length became dramatically shortened,

Something happened to the translation - hotels fimed?

黃大丙
2017-05-22 12:19:30

typo, hotels --> hole

Charlie Ting

You can have some procedures to avoid this issue.

邢鳳言
2017-05-22 12:28:09

"hotend", spell check problem...

Charlie Ting
2017-05-22 12:30:19

For example, each time when you finish printing with any filament, move hotend aside and extrude some filament out from hotend then retract quickly. (So this string will be as short as possible)

Then pull this filament back after the Y tube to have a clear path to put another filament in.

It's not difficult to do this, but a little bothering.

Birk Binnard

Hi Charlie - that's exactly what Simplify3D does when it makes a tool change. I found that it works pretty well for small parts, but most of mine are large and for a large one (print time more than say 3 - 5 hours) I consistently got a clogged hotend.

This, in turn, required complete disassembly of the hot end and torching the nozzle with a propane torch to clean out carbonized filament. Since doing this requires cutting & re-soldering wires there are only so many times this can be done before spare parts are needed.

Charlie Ting
2017-05-22 15:36:14

it means your nozzle has something wrong. I think these may happen in your system:
1. Cooling fan is not perform well to cold the nozzle down. (the throat)
2. The thermal resistance of your nozzle is too high.
3. The O-ring is mal-function to resist the thermal passing through.
4. The PTFE tube transfer too much heat from the head to the filament.

You should try to make sure all these works fine, not clean them every time. XDD

Birk Binnard
2017-05-22 20:30:45

Thanks Charlie - I see what you mean now. What you say is certainly possible since my hotend is comprised of parts from 2.0 & 2.5 EX and is totally non-standard. I'll try some different configurations and see what I can figure out.

Birk Binnard
2017-05-24 02:50:15

I think I may have solved this problem. Here is my blog page explaining what happened and what I did to fix things: http://wp.me/P8JtoQ-96

I also have this issue

Harry Cayne

I tried to push the ptfe tube as deep as I could but still

Dennis Chen
2017-05-28 16:18:50

Did you try to push the ptfe by rotating it at the same time with the heated nozzle? This would make it even closer to the bottom.

Harry Cayne

想請問一下各位，ATOM 2.5 EX 列印到一半後，有列印動作，但噴頭沒有線跑出來，發現整個噴頭沒有加溫，我將機器關掉後，再打開PREHEAT，發現依舊沒有升溫的動作，請問這該往哪個問題方向去找，謝謝

假日愉快~
有個奇怪問題價大家,
之前列印都還滿正常的
但至從上一次突然列印到一半擠出線材感覺沒有黏在列印件上,
一直黏在噴頭,
直到我去看到發現噴頭黏了一坨,
但還好沒有黏的很嚴重(約小指頭再少一半)
我原以為鐵氟龍關該換了,
但拆開還滿乾淨的,都沒燒黑的的現象...
但還是換了一根新的,
可是之後列印都常出現列印一段時間上頭的送料馬達還在持續送料,
但下面噴頭卻一直沒有擠出線....
我將噴頭加熱後將線材拉開用,
最小的六角板手清時,
感覺板手一伸進去到近底部時就會有一坨料在裏頭,
(有一個阻力,板手推下去後,噴頭大約可擠出約1~20mm的線)
但只要再用廢料線推一推又用板手清一清後就可以再印個幾小時~對就擠小時...這樣怎麼印東西呢?
請問大家有運到這類似問題嗎?
換其他料也一樣.....
改如何排除呢~感謝大家

曾荐宏

拉高噴頭温度列印看看，還有看一下列印時温度有沒有飄移的不正常

廖新弘
2017-05-20 17:02:30

有可能那棬料不純，或者受潮

林志誠
2017-05-20 18:20:18

有可能是擠料輪出問題?!

之前電控板有燒到一個F5的保險絲，我已經短路過去，可以正常開機，今天把噴頭裝好後進行校正，然後就出現下面影片現象，用Home也怪怪的，軟體已經重新更新過，請問該從那裡下手呢？

翁士翔
2017-05-20 12:03:28

我之前除了F5保險燒了之外8825晶片也跟著燒了，造成馬達運作不正常，全更換後就沒問題了，不知道這台是不是也有一樣的狀況?

Jeff Lin
2017-05-20 12:03:51

買新的就好了

張育仁
2017-05-20 12:05:31

跑的特別快的那一軸是不是驅動板的MS1或是MS2的腳位壞掉或是沒接好

張育仁
2017-05-20 12:07:03

或是主板上相對應的pin output有問題

林君遠
2017-05-20 12:09:46

如果要更換是要直接找ATOM客服買?

Moko Jenson Huang
2017-05-20 13:20:31

8255交換試驗看看－或是乾脆全部一起換。

廖新弘

小弟雖然圖一有進步一點
不像圖二那麼誇張塌掉
不知如何在調整為更好
請求前輩指導了
圖3-5為目前設定
Atom主機設定118%速度

高北熊

後來有開支撐
但底部沒有打底
上面太重往下壓了一點
上面一半都變形

Merry Jason
2017-05-22 13:07:07

這裡在模擬的時候就會破洞
做出來也是如此
請問有方法解決嗎

Chen Willy
2017-05-24 01:30:12

可以請問大神，我換了喉管後用六角板手將噴頭做積碳的清潔，甚至用達火機將裡面的積碳燒掉，但是換了喉管後噴出來的問題有進料不順的問題，不知道是哪邊出了錯誤，可以問是什麼原因

黃俊傑
2017-05-19 14:38:06

你的料新開的喔？有試過別捲嘛？

Hsu YI Chia
2017-05-19 15:19:16

進料馬達的齒輪有同步嘛？是否有粉末積料摩擦力過大

Moko Jenson Huang
2017-05-19 16:28:24

一下子好一下子又不好，是不是線捲的不好。

Dennis Chen
2017-05-19 16:42:52

要不要監看一下溫度，該不會熱敏快掛了吧?

Moko Jenson Huang

順便看一下你的後風扇有沒有正常出力，是不是有卡卡的。

梁琄
2017-05-19 16:48:31

積碳有用一段pla去粘粘看嗎？有可能裡面還沒清乾淨
也有可能料有受潮喔
