那是耐熱膠帶，不用管它

感謝回答. 不用拆掉重裝，真是太感動了.......

單純拆喉管不難啊，風扇別拆

上蓋應該要拆下來吧?! 我光上蓋就鎖到快翻臉了... ^^;

兩顆螺絲而已不是嗎？
上下分離之後拆不銹鋼片，然後再拆快速接頭，就可以把喉管滑出來了，反而是回裝要塞線比較煩

@陳順得 好，我下次試試。(希望不會有下次 :) )

摩西www
試試看底部上口紅膠
讓底層咬比較緊就比較不會翹起了

我有上了說

白色的就是沒黏好

的確是沒黏好，是要塗厚點嗎

拿乾淨的濕紙巾撫平，然後等他徹底乾，沒有雜物在上面然後膠夠平整就好

成品的關節很鬆，所以無法站立

想玩的人可以試試，但是支撐不是KISSlicer，而是另一套軟體Simplify3D

最新測試版，使用KISSlicer支撐，將物體提高45度後列印，減少支撐面積，效果還不錯，但是不是使用趴著版，改採用原本的站立版

上面的版本，我的gcode有拿掉G29，直接設定Z offset 0.3MM

Birk, did you calibrate your reference voltage on all stepper drivers? I believe there is a page saying how to do it on your manual, since I don't run Ramps with Marlin firmware anymore, I do not sure the steps and values for the job. But it looks like your stepper driver was drawing current incorrectly.

No. There is no discussion about voltages in the Atom2 manual. Fortunately I do have a multi-meter that could do the job. But - what to check? Where to check? And what are proper voltage readings?

Is there a bottle of the lubrication oil from ATOM within your kits?
use it on magnetic rod & balls + linear slides.

Yes there is. I was going to ask about that - should I lubricate the ball joints and slide rails? Everything seems to move very smoothly and nicely right out of the kit, but I will (carefully) apply lubricant and see if that helps.

Thanks for the suggestion.

check the DRV8825 Vref to calculate your current limit on stepper motor
Consider to tune it a little up or down for your stepper motor. …… 查看更多

Here is another need to check item: check your three belts tension, if it is too tight or too loose, it will miss step as well....

if you want to check Vref, it should be 0.3 ~ 0.35V

I used a Q-tip to apply lubricant to the magnetic joints and slides. And I checked the tension on the belts which seems OK. I have never observed any slipping of the belts on their drive pulleys.

When I try the 300height part the following things happ …… 查看更多

I checked voltages (VRef) on all the steppers: X = 0.40, Y = 0.41, Z = 0.38, E = 0.38. To do this I used the top of the potentiometer and the lower right pin as viewed from the front of the Atom2.

These are all over 0.35 - so should I turn them all down to the range 0.3 - 0.35? …… 查看更多

Yes, try to lower it to 0.3~0.35 and let us know the result... :)

Results not good - I set the voltages to X = 0.326, Y= 0.333, Z = 0.325, E = 0.344. After doing Auto-Home and Auto-Level OK I heated extruder to 200 and started print of test part. video shows results.

https://drive.google.com/....../0B3EpEEIPcV....../view......

I tried Auto-Home and Auto-Level a few more times and they function OK. I will try printing a different model - perhaps there is something wrong or peculiar with the 300height model GCode.

Same result - from LCD Auto-Home and Auto-Level work fine. But attempting to print 50x50Vase resulted in same problem as above.

In an attempt to isolate the problem I created a new GCode file Using Repetier/Slic3r. Same result as video above, so I'm thinking that whatever the problem is, it is somewhere in the printer.

When you just auto home, is it movable by hand on 3 towers cart ?

Yes, but with more effort than when power is off

It shouldn't movable by hand when power on & just G28(Auto home)
If it's like that, check the pulley set screws.

I stand corrected - sorry. You are correct - the carts do not move when power is on following Auto-Home. And I did check set-screws - all are tight.

So, we need to check is belt too tight or not. But it's a little hard to describe it. Actually I don't sure what is a good range / standard.
Besides that, After lowering the Vref on DRV8825 , is the problem getting worse? Try to increase a little. (my guess is: the Vref might be fine between 0.2 ~ 0.6V) Try to find a value it's not vibrating & noising. …… 查看更多

I understand what you mean about belt tension. I do believe the tension is OK. I have never seen a belt slip on any drive wheel. With power off moving carts by hand turns drive wheel with no slippage.

Changing the voltages did not seem to have any sig …… 查看更多

But too tight belt tension, might increase too much driver load. So, it's the reason why I am asking if it's too tight.^^

OK - I can try to reduce the tension and see how that affects things.

Also make sure the belt is parallel to the linear guideway. If it's not, adjust the bottom pulley & upper idler bearing position.
Also make sure the linear guideway is installed vertically.

Yes, I understand that. The belts are parallel now.

OK - belts now have reduced tension. For all 3 belts, the tension on the side not connected to the tensioner is less than on the side that is connected to the tensioner. Also, it now takes less pressure to move the carts by hand.

Auto-Home & Auto-Level completed OK. Heating now; will try 50x50 test when at temp.

Printing looks good so far - half way through bottom layer and doing OK

Well it got to about the 6th level and then drove the extruder into the bottom layer and knocked off one of the carbon fiber rods from the Z column. It looks like there was also a problem with the extruder not feeding filament on the second interior layer of the bottom.

What's the Vref now? consider to increase a little.
For the Extruder, could you photo the extruder mechenical? need to check the installation. The upper right corner screw should not be tight, it should be movable with push to the arm. And return back to the position by the spring. …… 查看更多

I have to take the build plate off etc. to get the voltages. I will post that info tomorrow. I believe the extruder parts are OK - the top right screw is loose enough to allow the arm to move OK, and the filament does pass through extruder OK. When p …… 查看更多

pla當然是不行啊....

我的水壓大概是1kg，那3d列印裡有我適合用的嗎?

先用3DP印出模型來，然後再用模型去做出模具，然後灌模就可以了

你的殼厚可能要足夠才能抵擋1kg的壓力.....

謝謝你們的回答...我本來是用車床做的..只是想3d列印有沒有辦法讓我偷懶一點...

用車的啦....你印到可以用的時候車床大概早就做完加上測試完成了.....

恩恩

既然會車床，就車個模具灌模就好啦

請問您線軌所更換的規格是什麼呢？另外要如何取得...？可麻煩告知嗎？感謝您

滑軌規格是~MR9MLSS1V1N-600L~CPC的~需要資料嗎

好的! 麻煩您 感激

會沒跟上銀購買~是因為在我們機械業~其實傳出滿多假上銀的聲音~遇到雷也滿多的了~

感謝大哥提供寶貴資訊！

不用客氣的~

你的線軌也是會晃了嗎

我預購了 stom2.0. 想先自行將相關零組件 升級 必免未來產生的問題！！只是要先確定2.0與1.0有共用！！

了解~希望官方新版本的線軌能採用穩定點的廠家~因為在我們1.0~好像滿多隻都有出現線軌有問題的狀況~再加上此次更換~已經連跑快24小時~線軌面都是光滑面~並無像舊的跑不久就開始出現黑油汁狀況~那代表磨耗真的是很快又很嚴重~

但還是要支持台灣這群年輕的這份衝勁與創新、這樣新世代才會成長、讓一些只願意付香蕉的企業主、無法生存下去！！

2.0標準出貨就是CPC囉

讚唷

我還以為還是上銀

不會影響切片，直接按 continue silcing 就好了，只是告訴你的記憶體不足

Misc tab-> Ram warning 可調...
只是警告用,避免切片切到你電腦暫時記憶體不足....

要按第一個按鈕才不會被window踢掉歐

我有印過3mm的圓柱插銷⋯⋯但就算速度降到10%還是溶掉像蠟燭台一樣。 可能人的問題吧⋯⋯我是一代

如果只是單純小的話....

這是掉地上的支撐撿來拍嗎?..誤

哈哈~

我印的那根螺絲放桌上, 我也誤以為是屑屑差點要丟了 XD

其實我比較愛用藍色膠帶、一條可以印超久^^

我還在找我附近在哪買

請問藍色膠帶的商品名稱是啥

ATOM 團購首發3M 2090 藍色膠帶大家有興趣嗎？

要自己買的話可以到http://tb.cn/zKPOIBy?sm=c9caf5

為什麼貼這個膠帶能防剝離呢? 它是雙面膠嗎? 看商品說明是"油漆作业中的遮蔽应用" 覺得疑惑...

一切盡在不言中、只推好東西^^

口紅膠就先隨便塗一塗, 再滴個幾滴水,
拿個菜瓜布刷一刷, 讓口紅膠跟水混在一起, 變成稀的口紅膠水~
然後就慢慢刷平, 等它乾, 就平整了~

3M 2090, 或 Kapton 也都不錯用, 好拆.
但我個人還是喜歡口紅膠, 黏的比較牢, 也不算太難拆

一起用派

油漆行不知買不買的到。

請問，藍色膠帶怎麼用？把玻璃貼起來就行了？

原則上膠帶只是讓第一層較容易咬住而已，所以只要貼平整就好

核心零件都是ATOM的功勞～

5um以下的粉塵就沒有什麼效果了.....試試看吸吸看麵粉.....我得到了慘大失敗....XD

玩模型的過程中桌上總是有塑膠碎屑，我是為了吸這個才做的～

我的大的比較夠看...12V 2.5A的蝸牛扇, 吸力還不錯....但是吸麵粉大概有70%的分離率而已....我是做來吸麵粉的....XD

意思是有30%的麵粉會從出風口被吹出來？

對, 看到下面收集袋有粉出來沒錯, 但是出風口也有淡淡白煙飄出 ....最後秤重大概只收集到70%......麵粉的顆粒從1um到100um....所以5um以下的沒辦法分離.....所以我另外有做了12氣漩的等待實驗
