Is there a photo about the fall off "magnetic bearings"?
Another photo needed for the controller board.
Is it still accessible via Pronterface?

god！有夠厲害！

大隻的就ok, 小隻的還是要去買金屬的啦~ XDDDD

認真的我M12有一包在家裡XD

For 2, you need to check if you connect the wrong pin on the micro switch, it should be C(Common) & NO(Normally Open), and the switch is pressed when nozzle does not touch the bed (Stay open). When touch the bed, nozzle moves and micro switch becomes close and it triggered Z Min. the Pins are labelled on the switch as well.

For 4. The always on fan always face rear. You probably put it 180 degree reversed. The two side blowers are activated by the slicer when looping and cooling. Or you can turn it on manually on control > Temperature > Fan Speed. Jog dial set it to 255 should bring the blowers to max speed.

Another need to check item for 2: You need to check the three top limiter one at a time, starting from the X (the left hand side) and then the Y (the right hand side) and finally Z (the rear one) . When in the middle, M119 should returns all open, and …… 查看更多

Excellent info Bato - thanks. The Fan Speed does control the side blowing fans OK - they start and stop as expected with Fan Speed set to 125 & 0.

I have checked the 3 top limit switches as you describe and each one does show open & closed at the correct time. I will check to see if I have the wires for the extruder limit switch reversed somewhere.

For 3, it look like your stepper connectors are plugged into the wrong sockets. (And maybe it related to 1.) in Pronterface, X should move the nozzle left/right, Y for front/back, Z for up/down. you need to check your stepper connectors are in right place.

I have checked the 4 limit switches and found nothing wrong - except Z min is always triggered. The Z min limit switch came pre-wired with 2 yellow wires leading into a plastic connector. This connector fits only one way into the yellow connector on th …… 查看更多

No, don't cut the wire and reverse it yet. You need to check the Z-min micro switch carefully, don't cut the wire yet, you need to check with the two yellow wires soldered to which pins on the micro switch, if possible, take a picture and post here for better understanding.

OK. I will have to disassemble the print head to do that - working on that now.

OK - here is a photo of the switch:

Hmm... looks fine to me, it is C and NO soldered.....

But the switch works - it just works in the opposite way it is supposed to.

I really don't understand this because I thought microswitches could only be open or closed, meaning they either short the 2 wires together, or they don't. And this should …… 查看更多

I'm going to put the print head back together now. Have you ever heard of "letting the evil spirits out"? Believe it or not, that has worked for me a few times in the past. Maybe I'll get lucky again.

Hi,Bric .Please connect your printer with Pronterface,than send M502,and send G28 ,if the problem is still there....I suggest,record a video to show what situation you got, let us to help you to solve those problem you got,thanks

OK - will post results and video as soon as I get things back together.

Make sure to upgrade your Marlin again

Yes, I did that first thing this morning. Still working on printhead re-assembly. Those sure are small fasteners!

No joy. I used Pronterface to give the 2 commands. First one worked OK; second one did the same thing as the LCD AutoHome: extruder moved to top and Y sterper went crazy. See video for the gruesome details.

OK - Facebook won't upload the video - it's 113.MB. I'll upload it to my Google drive. Here's the link for it: …… 查看更多

it look like your endstop didn't work,

or your switch broke

I don't think so - because Pronterface shows each limit switch being tripped when I activate them individually by hand.

Birk Binnard Could you check each endstops & stepper motors relation?
X axis : left stepper motor [X MAX ]
Y axis: right stepper motor [Y MAX[ …… 查看更多

After about 2 1/2 hours online with an Atom tech the following has been established:
1. Each stepper motor, when running individually, works Ok and stops OK at it's top end-stop.
2. The X & Z steppers and the Y & Z steppers function properly together a …… 查看更多

那個包覆電線的絕緣熱縮套，尤其那個透明要保管好

廖兄你好:
你說"那個透明要保管好"(鐵氟龍管) 請問它的用處是什麼?

感謝你!!

這三樣都是備用的喔，先收好就好:
大的熱縮管是用於整理固定連接噴頭五顏六色的線的。
小的熱縮管是用於焊接後的保護固定用。
最後鐵氟龍管是可以用於噴頭替換用的，一般來講之後列印溫度保持在240度以下(PLA大部分180~220之間就夠了)，鐵氟龍管就不易變形，不會有更換的需要

感謝說明!!但是鐵氟龍管的說明還是不太懂?

噴頭內部有一根鐵氟龍管在裡面，只要保持在適當的溫度，裡面的鐵氟龍管就不會變形囉

那是鐵氟龍管嗎？怎麼看起來那麼小？鐵氟龍管不是有100cm？還是旁邊的熱縮套特巨大...

那是喉管內的3*2的鐵氟龍管

何謂喉管?

喉管就是噴頭上的那隻鈦合金的管子

感謝幫忙！！

為何1代升級用戶無法使用~差異是????

因為 1.0 跟 2.0 的韌體不一樣, 我只有改 2.0 的 XD

我下載來改一下好了~ XD

因為是32位元的板?

板子基本上一樣是8位元而已, 少部分不一樣.

請服用, 希望不會弄壞掉 XD

https://www.facebook.com/groups/atom3dp/1597514300486859/

酷耶!!

我有點想另外買一台2.0了...忍著 座等3.0

1.0也可以用拉，沒有不能用的道理

1.0的USB接頭燒了無法更新，哭哭

1.0跟2.0的差異主要是Stepper driver...從A4988換成DRV8825...所以韌體裡面的步數設定整個不一樣....會改的話, 其實是可以直接用2.0的韌體改在1.0上面用的

嗯!?
韌體裡面改變步數的設定？
可以詳細講嗎？

# define DEFAULT_AXIS_STEPS_PER_UNIT {160, 160, 160, 200}

指的就是這行設定

在面板上的話，對應的是Xsteps/mm ?

應該是吧 XD

這....歷史一再重演... 菊印也很利？
請多保重..
手不要放在刀前攻擊範圍內... @@

林肯的詛咒... (誤)

http://diy3dprint.blogspot.tw/p/blog-page_20.html

感謝關心~我是四周先鏟一點起來...還是很緊~左手放在雕像後面...右手一用力突然菊印就發威了~瞬間鏟過去~然後大拇指就中獎了...大概3CM的傷口...冏...

我有看過這篇...還是中獎了

可以考慮搭橡膠陲使用...

沒受傷過的，一定沒用過3DP

燙傷, 割傷, 刺傷, 毒氣傷害, 小朋友離家出走

還缺啥沒提到? XD

電到

被3DP虐待, 心理受傷害

我第一天組裝鋁擠柱的時候就見血了，想說怎麼鋁擠柱溼溼的，衛生紙一擦才發現手指的傷口XD

我兒子被一捲PLA砸傷腳趾...

這樣也能受傷？厲害

infill 減速看看....

嗯嗯~還有A4988~XYZ和出料的電壓是多少@@減速也會失步...是0.8-1還是影片那樣要調到1.49呀

1.x升級2.0 ?

沒~我還在1.0

步進馬達哪一顆?...Minebea的話好像是0.4V Vref ?

疑~是卡的電壓~看說明書是寫0.8-1

有好幾個infill要減哪一個才對@@

http://www.simplyalt.com/atom/viewthread.php?tid=687......

我的是紅卡~只有一個螺絲

http://www.simplyalt.com/atom/viewthread.php?tid=22......

這1.0-1.3~我之前是調1.2~也有失步問題~@@昨晚調降到1.0~也是有~還是真的要調到0.8...

有散熱片跟吹風散熱嗎?
線軌有沒有潤滑保養?
皮帶有沒有適度張力?..催太緊對馬達負擔會太大...

有吹風散熱~線軌潤滑正常~皮帶沒硬拉~就大概拉緊而已~

不過所謂的失步如果是因為印出來的東西冷卻不及翹起撞到..
那就不用太去動馬達了...還是從冷卻印出來的東西下手比較實際...

不是冷卻問題~因為只在印平面~為了蜂巢要填好~降慢到30趴~就下一層整個外型失步了~不調還沒事

infill是調整哪一個，我內部填充的蜂巢也很慘....

Printer -> Speed -> 那頁現在是? (這頁設定最大最小)
Solid infill: 封頂封底用
Solid infill and support speed: 其他的infill 蜂巢應該也是歸這個
Speed拉桿決定設定在最大最小之間的速度(早期版本在右側)

嗯嗯~晚點改看看~電壓調看看~行不行~再跟您請教~感謝呢

馬達本身是相同的但是搭配的線是不同的

所以步驟E中的步進馬達應該是長線的

可不可以徵求組裝協助阿.....T_T(在台中)

組裝有問題就上來問吧~ XD

微動開關中間的端子折彎可否? 沒有斜口鉗

最好剪掉，好像會誤動作跟頂到機構

OK 我有確保不會頂到M3螺絲 不過 我還是去買把斜口鉗好了

在C02要如何將電線沿著中心穿出啊?還有微動開關端子(3孔)在哪?怎麼第一個盒子裡面沒有

C02 是什麼 XD

C-02g是步驟我穿過去了，微動開關端子(3孔)找不到，怎麼辦?

應該在 box7 吧? 一堆電子零件的那盒

Oh....在box4

可以拿送的那隻起子用來輔助穿2040中心孔的線...

我也是這樣穿的

但... 別急著穿 Z 軸, 因為後面還有一大捆也要穿, 到時一起

去找條棉線先穿過去, 到時幫忙拉那一大捆 XD

喔....你是說微動開關線先不要穿過鋁擠中心嗎?

Z軸而已, 因為還有擠出頭的一堆線要穿過 Z 軸
