依我現在的改造程度, 只能提供陽春 PLA 防潮箱供參考, 改日仍要朝用櫃子全封起來控溫改熱床著手. 才剛用一周, 至少還沒有因天冷下雨隔日線材自動折斷的症狀, 左方白色物是吸水包, 右方自印線軸支撐, 外殼是神奇改造箱 K-013, 不知已經有點受潮的線經過長期放置後能否脫潮換線. 外殼將線材與擠線器都包起來, 需自行挖孔...比較厚圈的線軸無法使用, 可以找他兄弟 K-015 ( "大" 賣場有售)

Replacing nozzle thermistor

This is not a job for the faint of heart. The first problem is getting the old thermistor out of the nozzle. I tried pulling it out using the exposed wires, but this did not work. What happened was each wire broke off, leaving the tiny thermistor stuck inside the nozzle. So I had to literally drill it out using a 1/16" twist drill. Since the thermistor is glass and metal, this is not easy to do. It took several tries before I got it all out.

The second problem is the insulating plastic on the thermistor wires. I bought a roll of new insulation, but it turned out this was a tiny bit too fat to fit into the hole in the nozzle. So I had to re-use the very thin plastic insulation from the original thermistor. Therefore it is very important to keep this insulation and not destroy it when removing the old thermistor.

I also bought some shrink-wrap tubes to cover the solder joints between the new thermistor wires and the yellow wires in the hot-end wiring harness. Obviously you have to remember to put the shrink-wrap tubes on the yellow wires before you solder them the the new thermistor wires. I wonder how many people forget to do this. In my case I just slipped the shrink-wrap tubes over the solder joints and really see no need to heat them.

I checked the results by doing a pre-heat to 200 and everything seems OK. Now I just have to reassemble everything and try printing.

Reassembly was pretty straightforward until I discovered that the new side-blowing fans I have appear to be very slightly larger/wider than the ones I had previously. The net result of this was that the edges of the fans rubbed against the sides of the …… 查看更多

I think you can get the PTFE tube, thermistor on ebay. The ceramic ring heater is the tricky part to get in US, I ordered it on taobao.com. But even you order a replacement hotend, you might still need to fix the old one, since the Titanium nozzle is still good to use. Anyway, Congrats to you, ATOM2 is good to go again. :)

I don't understand what's magnetic about the Thingiverse printed effector. The caption says it needs no Z-min stop - but why not? What enables it to tell where the print bed is?

And what about all the wires? Are there connectors you can get that let you plug and unplug the wires? I am not that good at soldering those tiny wires.

Clarence Lee
2016-01-06 08:03:01

可能要改sd卡電源供應

張維哲
2016-01-06 10:10:47

稍微爬了一下若要改Printer的firmware 應該是需增加iSDIO的部分而SD電源還沒驗証過而電源部分最大需求為 0.72W 3.6V 200mA

Clarence Lee
2016-01-06 10:14:00

應該不是 fw問題...
主要是 power的部分可能無法讓Toshiba FlashAir的wifi部分的系統成功boot起來...
我在smoothieboard的電源供應上跑下來是沒問題的 (因為3.3v來自板子上)
Marlin架構的通常RAMPS1.4 or MKS GEN是板子上的5v-> lcd模組上的5->3.3V ldo -> SD

張維哲
2016-01-06 10:15:55

了解所以很有可能是電流不足work 似乎會比改寫fw好處理

James Lin
2016-01-06 10:21:44

請問
1. smoothieboard 你用的FW是一樣的還是哪一門派的?
2. 此板有支持網路(LAN)功能為何還要用 Wifi SD Card ?

Clarence Lee
2016-01-06 10:24:17

smoothieboard只有一種fw smoothieware
http://smoothieware.org/

夠理解smoothieboard的架構的話就知道他的spi write sd card那段很慢
他的ethernet只會想拿來控制,不會想拿來傳gcode到sd卡上...

James Lin

請問用這的優點是什麼?
假設我直接換需要改變什麼?

Noki Noki

這種卡片，無限存取只能讀出不能寫入，且要特定軟體才行

Clarence Lee
2016-01-06 10:37:53

一般的Wifi-SD是只能透過wifi讀為主...
但Toshiba FlashAir有提供介面經過設定可以
透過http 介面有upload 的部分...
所以不用特定軟體,只要是這張卡...

張維哲

因沒有玩過SD卡剛剛查了IO定義直接送電不會WORK 不曉得是否需要外部CLK信號想先排除硬體問題或是FW造成不支援

張維哲
2016-01-06 12:30:17

最初用電源供應器測試僅提供電源測試失敗後，改用土方法測試過找一台完全獨不到記憶卡的舊型SD讀卡機把記憶卡接點遮蔽僅留CMD VDD VSS可以找到SSID但一下子後就找不到，所以比較偏向是FW支援的問題，在來看看您貼的這篇

Clarence Lee
2016-01-06 12:35:25

他要3.3V 200mA左右..
但以前我在marlin測試其實已時後在reset過程會突然成功..

張維哲
2016-01-06 12:36:26

看來兩個層面都需解決才能運作

Clarence Lee
2016-01-06 12:43:24

恩..補個電容在3.3V那邊應該是比較好...

Clarence Lee
2016-01-06 22:45:14

Marlin驗證確定patch完可以用了..

張維哲

我的線軸橫躺在同位置但貼鋁材, 轉久了線會落在捲軸下層往內擠, 形成擠線馬達拉線辛苦, 稍內數圈的線材會自動鬆脫的怪異現象; 我這現象應該是線軸橫躺就會有, 不知道加了導線輪有沒有幫助? 其實我想在換下一個線軸時幫加一個自動裝置, 當線緊繃被偵測時自動幫線軸轉幾度 XD

Moai 可以在thingiverse 上找到，我當初是好玩，隨手拿以前印好的moai 用雙面膠黏上，所以不是什麼特別設計。您也可以在導料輪上面放自己喜歡的東西，然後看它旋轉：)

有些線卷太滿橫躺就會鬆脫,所以我現在會依線材的狀況,不用"ATOM超滑順萬用料架" ,
改為直立+導輪反而安全

又一個慘痛的經驗=.=

睡前看起來很正常結果一覺睡醒噴頭卡住了看到噴頭在那邊懸空空轉將近50個小時就這樣噴了....

大力抽出料後發現前方黏黏的會不會是口紅膠堵住頭了?

回抽地獄出現了，抽回太頻繁，線材把熱從尖端帶回到喉管，喉管升溫再把後段的料熔融、膨脹，逐漸增大的摩擦力最終導致擠料機構的失效。
解決方案，減少抽回長度(約5就夠用)，減慢回推速度（使用Kisslicer1.5版以上），降低回抽頻率（加大min jump以及Trigger）
