one more (last ) i have a very high min zero offset level : 0.66 and it change from one print to another each time i recalibrate following the 2.03 firmware procedure, from 0.57 to 0.7, is there something wrong ? thanks a lot everybody, and by the way i follow the group for 6 months now and congratulations to everyone that got so beautifull prints !
黃俊傑 2015-12-02 10:05:46
sounds like "E. Distance between end stop and screw". check this website to fix it,step by step. if still same,just try to print something and take first layer photo. …… 查看更多

Firmware 2.03 Z-Adjust weirdness
Note that I recently installed a Zebra Plate on my Atom2 and, as the instructions stated, had to readjust my Z offset because the Zebra Plate is VERY sensitive to the 1st layer's extruder height. After a number of experiments with printing test parts I finally ended up with this statement in my GCode header: G29 Z+0.525 ;auto level
This value of 0.525 resulted in good first layer adhesion and layer depth and I printed a number of parts A-OK. After printing my first good test part I put a ; in front of the above statement since the offset is stored in the motherboard EEPROM.
Then I saw that firmware 2.03 was available; since I was running 2.01 I figured it would be a good idea to catch up and I installed 2.03 with no problems. I looked at the Z-Adjust video and decided to try it since I had never done the paper test procedure before.
My initial trial value was Z+0.3 and that was too tight; I could not move the paper at all after Goto Zero. Next I tried Z+0.4 and that was better, but there was still a fair amount of pressure on the paper when it moved. So I tried Z+0.45 and that seemed right on - the paper moved pretty easily but still maintained contact with the bottom of the hot end.
I figured I was good to go so I tried printing a real part. But the first layer did not extrude at all - it was clear the hot end was too close to the Zebra Plate. So I went back to the Z-adjust procedure and increased it to Z+0.5. This seemed too loose when I did the paper test but I left it anyway. My next print was only slightly better - the 1st layer was barely visible .
At this point I decided to go back to the old way and ran a test part with G29 Z+0.525 ;auto level in the GCode header. This worked well and that's where I am now - of course with that statement commented out.
I'm not sure what conclusion to draw from all this. Perhaps it means the paper test simply doesn't work with Zebra Plates. Perhaps I made some mistake somewhere or left out a key step. At any rate my printer is printing fine; I'll have some more interesting posts tomorrow or the next day.

Is it possible to z adjust 0.525? Or 0.52 0.53
Birk Binnard 2015-11-20 13:25:44
If I remember correctly I did try 0.520 and 0.530, but 0.525 was a better choice. I do understand that the steppers may not be capable of making a move as small as 0.005mm; all I can say is 0.525 seemed to work best in my situation.
Clarence Lee 2015-11-20 13:28:16
It’s possible. My branch of the revision might implemented the support of the 0.001mm z offset runtime adjustment.
Clarence Lee 2015-11-20 14:37:51
err, after review code, current via lcd most small scale is 0.01mm. It's possible to add function to implement it. What is your first layer height?
Birk Binnard 2015-11-20 23:09:21
Well I just had an interesting experience! When I started to print a new part I turned on the printer, did Auto Home, and began printing. The GCode for the part to print had the G29 Z+0.525 statement commented out. But when the printhead reached the build plate it crashed into the plate and disconnected 4 magnetic arms. Needless to say I stopped the printer, re-sliced the part with the comment removed from the G28 line, and now the part is printing OK. This makes me think the results of the G29 command, when executed from a print, is not being stored in the EEPROM. But is this possible? And how to find out? Is there a way to display the vaues stored in the EEPROM?
Clarence Lee 2015-11-21 00:06:01
use pronterface, when connet or M503 displayed the saved array
Birk Binnard 2015-11-21 01:14:16
Thanks Clarence - I don't have Pronterface anymore but I can use SImplify3D to do the M503. I'll post results back here probably tomorrow.

劉宏威 2015-11-19 21:43:40
控制板不會是問題…… 總有種一代用戶不太被注重的感覺… 之前一代雷射的韌體大bug很久才修復, 官方也沒有主動給一代用戶任何消息, 還是我自己問才知道bug已經修復了。 我也不諱言,身為一代升級二代的用戶,我對atom蠻失望的。 要知道如果沒有一代用戶,atom哪裡會有現在二代的成功?

蘇子敬 2015-11-20 08:26:40
片翼之鳶 剛看到birk binnard的留言,他用2.03加zp,set z level後,第一層印不出來。就是因為沒有改manual_z_home_pos嗎?

照理說這個參數只是避免你一開始撞噴頭而已... 應該是其他原因吧?

李穆 2015-11-20 12:33:45
[以下方法適用在2.0.2版以前韌體]先用10%跑一遍G29(面板上的AutoLevel),連上電腦後用pronterface打G1 Z2 F8000,再用pronterface的「Z向下0.1」的按鈕慢慢降到快貼板,看一下LCD上顯示的Z值後重新用電腦輸入G29 Z+**再用10%速度跑一遍。(記得要先解決"上蓋太緊"的問題)

Is this a firmware bug?
These are small scratches in my Zebra Plate that happened when I was doing several test prints and used the LCD panel Stop Print function while the printer was printing the first layer..
When I did this the print head kept moving along it's current path for several mm and at the same time sounded like it was gouging the plate. This happened a few times before I figured out the way to avoid it was to first use the Pause Print function followed by Home and then Stop Print.
Pause stops the printer immediately so there is no change of anything bad happening.So that's what I do now if I have to stop a print on the first layer.
But shouldn't Stop Print do the same thing - stop everything immediately?
André Medborg 2015-11-09 07:51:43
My printer stops immediatly when I press stop, but only after the first layer. I normally shut it down. If it dives the build plate. Actually I have been experimenting with BuildTag a while back, but I abanded it cause I thought it was too expensive to keep replacing it.
André Medborg 2015-11-09 07:53:07
Birk what's up with the auto leveling marks on the plate - are they holes?
Birk Binnard 2015-11-09 08:05:50
No, they are not really holes at all. They seem to be just marks that do not affect the bottom of a print.
Clarence Lee 2015-11-09 09:32:41
after a little trace, pause & stop should be almost the same. the main difference after stop, it's turn off the heater & close the file reading.

New version of Craftware
The new versions of Craftware can be found here:
https://craftunique.com/craftware
I just printed a test part and there are some clear improvements:
1. Using the same settings I have from earlier versions it seems that the printer moves faster during all print operations.
2. Not only does the printer seem to print faster, but it is quieter while printing and the acceleration/deceleration moves are much smoother. I suspect this has a lot to do with making the printer quieter as it prints.
Birk Binnard 2015-11-06 01:24:42
Yes I know. But the Craftware software works very well on the Atom2 - better than Kisslicer in my opinion.
Clarence Lee 2015-11-06 09:09:12

André Medborg 2015-11-06 15:30:38
Yes CW does an awesome job. However after the upgrade the end position of the extruder is for some reason outside the primt area. This results in the printer doing the job but ends up cramping outside the extent print boarder. I can't seem to fix it. Any tips?
André Medborg 2015-11-06 16:02:12
Yeah got that right, but the problem remain. I also tried with a thin object and here the extruder print end point is within the perimeters, but moved next to it like on the picture but not as far. Once it finish printing and go to the "finish-point" it moves to home.
Birk Binnard 2015-11-06 16:11:06
Andre - that's odd. I had no problem, and all I did was Home & Level.

這是 Adam Chen 說的列印過程中溫度振盪巨烈的 gcode 檔案,溫度設定值 195度,我試印時它有時會掉到180度,並且LED操作介面幾乎不會回應。 個人判斷這絕對是Marlin太忙碌了、無遐去即時開關加熱,但個中比較實際的原因,我說不清楚。KISSlicer切片的。
Hawke ChienSheng Liu 2015-10-30 17:05:02
想試印的人,留意一下這個gcode的 bed_offset_z_mm = 0.25 所以第一層的列印高度已經是 0.45mm
戴士偉 2015-10-30 17:13:03
把 override 調整 50% 或更低試試 如果是來不及運算, 可以透過這方式去釐清.
Hawke ChienSheng Liu 2015-10-30 17:17:06
override 是 KISSlicer的設定值?
戴士偉 2015-10-30 17:18:58
sorry, cnc慣用語, 就是列印時調整旋扭讓它速度降 50%
Clarence Lee 2015-10-30 17:19:22
如果上面戴大建議的成立 可能的方法.. [A] configuration.h # define DELTA_SEGMENTS_PER_SECOND 120 往下降到80看看 [B] 把DRV8825設定成16細分(板子上跳jumper) DEFAULT_AXIS_STEPS_PER_UNIT 四個參數減半
戴士偉 2015-10-30 17:20:06
我看過影片跟gcode, 感覺不像是運算速度問題, 比較像是風扇吹到噴頭~
戴士偉 2015-10-30 17:21:16
運算速度問題還會有另一個現象, 走走停停
Hawke ChienSheng Liu 2015-10-30 17:29:37
它從第一層開始,物件風扇就255在吹了,是問題之一。不過我手動把它關了,仍然有 195 +/- 10 度的震盪,應該還有其它原因。運算量太大,我是以LCD面版旋鈕的旋轉、押按的反應速度來判斷的,這個case它幾乎不理我啊。 至於速度降到50%,有試過了,反應速度有些改善,但我仍覺得它慢。
Hawke ChienSheng Liu 2015-10-30 17:33:14
不過我是很想弄清楚 Adam 切片時是踩到什麼地雷,會造成這種溫度震盪。我用我的機器可以再現他的問題,而我平時用Cura 15.04 或KISSlicer 1.5 beta 2.22 切出來的gcode不會遇到這麼大的溫度震盪。
戴士偉 2015-10-30 17:48:43
再看了一次 gcode 還是沒發現異狀, 切出來的路徑挺單純的, 不太可能造成運算速度異常才是 @@

[集思廣益]
最近太忙了,想想反正自己又沒想要從套件賺錢,所以把心中的想法拿出來跟大家討論,看看大家有什麼建議,有興趣的人也可以自己實作看看。
就是之前測試軟料後,我發現徹底解決遠端進料系統在軟料(但其實不限任何料)的使用上,需要在進料馬達那邊加上一個外掛模組。
這個模組會在線料的前後各有二個感應器去偵測進料長度和出料長度,從中控制線料在進料馬達中的壓力和變形量。一旦進料太多,就透過觸發的方式讓進料馬達反轉退料。這部份可完全於機器和切圖程式隔絕,完全不受影響,只要修改一下 Marlin透過某個腳位控制即可。
目前比較沒時間收集和研究的是,怎樣的光學編碼器最合適(不用搞太大),以及偵測的頻率上限(避免 Prime/Suck時造成偵測失準),然後再透過 Arduino nano 去處理即可。(若直接裝在機板上,不確定中斷的發生頻率是否會影響列印過程。)
這個模組的概念很單純,在我測試軟料的過程中,唯一的變數就是線料變形卡死而已,其他就是順順的印,跟其他PLA都一樣,只是料性比較特別點。因此,只要作好這個模組,等於 ATOM 就從此不需再說自己是遠端進料。因為本質上跟近端進料差異不大了。(只剩回抽的線料變形變數 L偏大而已)
偵測方面,希望精度能到 0.1mm 左右。因為線料壓力大概在三個齒距內都還穩定,若超過三個齒距就開始可能變形。
我個人覺得,如果 ATOM 要推軟料,那麼這個模組要先著手開發。不然軟料發售後,將是災難的開始。反之,若有模組可用,使用軟料就像如履平地。
Rickey Yang 2015-10-24 23:13:45
不知道會不會有控制慣性的問題存在 ,在回抽時
Charlie Ting 2015-10-24 23:18:08
覺得還好,因為控制馬達的部份還是走 Marlin 的函示庫,這個模組主要是解決目前 3DP 在供料部份都是用理論值的方式計算,卻跟實際用料和材料特性脫勾,造成使用者只能用試誤法來列印。 但是,只要供料穩定,回抽或抹除就足以解決很多牽絲和溢料問題,等於不容易出錯。這樣使用者才能把心思放在模型設計和支撐上面。而不會因為線料的問題而失敗~~
鄭政浤 2015-10-24 23:18:40
我之前有想過(對! 又只有想orz) 要是能做一個把進料馬達 保持在噴頭上方的裝置 不是跟噴頭固定而是跟噴頭一起上下移動 減少遠端進料的距離 這樣在進料控制跟誤差會小很多 只是想拉....... 本來是想在滑軌上再加一組移動滑塊 但不知步進馬達力量夠不夠
Charlie Ting 2015-10-24 23:23:18
這我也有想過,但是我發現有更多問題會發生。 結構的問題不大,但是問題沒有根本解決(供料不準無法修正) 另外,未來如果多噴頭的機構成熟了,那麼空間是否足夠。還有,未來也有可能一般PLA、軟料、可溶解塑料一同列印。這時,多種特性不同的線料同時上場時,使用者會不會瘋掉? 還有列印風險會不會大到根本無法成功? 所以我希望的根本辦法是徹底解決線料供應的風險,剩下的愛怎麼作都無所謂。
李穆 2015-10-24 23:23:21
我之前有想過從快接頭游隙端的壓力來測試管內材料的應力,或是從擠料馬達輸出電流來反推,不過最近工作太忙了沒什麼時間靜下來研究實做的方式,先把靈感丟上來
Charlie Ting 2015-10-24 23:24:12
good idea, 值得想想~~
Kevin Chen 2015-10-24 23:27:18
擠料馬達輸出電流這個想法讚~比較安全穩定。
李穆 2015-10-24 23:27:56
機電跟程式的部份我大外行,不知道主板支不支援直接用函式計算擠出機電流電壓,也許可以不用作硬體改裝就達成了,不過這對我來說要從頭學起,目前還在摸基本的程式語言.......
Charlie Ting 2015-10-24 23:30:05
Kevin Chen 電流這部份的執行難度應該不低,而且可能失準。
Kevin Chen 2015-10-24 23:32:40
那我提供另一個想法,改機構而不用加偵測裝置。把擠出機彈簧改為可調式,並且把齒輪改為平滑輪避免擠出機推不動的時候刮傷線材,只要把彈簧張力調到線材變形前會夾不住而打滑,就能保障線材提供的背壓保持在最大,避免用回抽控制造成背壓不穩定而出料不穩定~這個概念還是有衍生的問題就是了
李穆 2015-10-24 23:34:43
這樣的話我會聯想到直接降擠出晶片的電壓,這樣寧可擠不動,也不會硬擠?
Kevin Chen 2015-10-24 23:35:02
會認為馬達電流是個不錯的想法是因為我們在合成這些高分子時其實也是由馬達的Kw值來判斷熔融態高分子黏度,如果能用馬達先確認各材料的變形前的最大電流值作為警戒線,或許也是一個方案(但難度真的就..我沒有電機背景真的無法想像XD)
Charlie Ting 2015-10-24 23:36:19
這個概念我有想過,但與其這樣作,我會寧可改滾輪兩側的金屬件,讓它沒有多餘的空間讓線料變型,這樣更單純。 因為現在主要的問題是線料進太多,只要能退出去就不會出事。然後盡量不傷線材即可。
Kevin Chen 2015-10-24 23:47:38
Charlie大說的改兩側金屬輪無多餘空間和Clarence大之前提過的PTFE管包夾概念類似,但其實壓力過大只要有縫它就會變形(被逼到絕路,和人一樣XD),如果沒有隙縫可以鑽也會因為阻力過大推不進去被進料齒輪刮壞~您提到的回抽控制方案其實對不卡料很有幫助,只是可能擔心會造成出料不穩定,我在長時間和極限條件列印時偶爾會手動把擠出機構鬆一下讓線才能把變形部分自行回彈,但觀察列印件就會發現我動手的地方反而出料量減少造成列印品有縫隙;李大用調降晶片電壓是怕你換回PLA又要再調過一次,會有點麻煩
李穆 2015-10-24 23:53:58
利用包裝內附的備用擠出晶片先調好TPE用的電壓設定,可以換插晶片或是利用第二擠出晶片的插槽搭配開關切換
Kevin Chen 2015-10-24 23:54:46
另外提到衍生問題,如果線材會有阻力造成變形而沒被擠出,其實代表實際出料量比軟體計算應該需要的出料量來得少,我會認為這代表輸出量無法滿足計算量可能會有壁厚偏差的問題(如果要求到這種程度的話...),所以基本上我都希望能盡量靠避免阻力累積,讓軟體進料量等於實際出料量,也就是最佳列印速度與溫度配合
Kevin Chen 2015-10-25 00:04:09
其實input=output壓力還是會累積喔~但那會是合理的背壓讓材料能穩定持續的出料(從塑膠加工的觀點來看的話),造成線材變形的背壓就是進料量太大以至於出料端來不及消化掉而持續累積,如果是塑膠押出成形用的螺桿押出機,就會看到口金壓力超過界線然後強迫停機~只是3D列印機沒有這樣的偵測裝置,如果不是考慮鐵氟龍管壽命把噴嘴溫度升到260搞不好可以看到這隻軟料在遠端機種上達到新境界
李穆 2015-10-25 00:05:22
抱歉我剛想了第二遍才想通,就把無腦的問題發言砍了
Kevin Chen 2015-10-25 00:11:01
別這麼說啦.如果3D列印的玩家都像您們幾位那麼認真,我就不用抓最佳條件抓得那麼辛苦了~我是因為對於控制系統還有機構沒有底子,沒辦法像你們幾位用控制系統的概念去解這些問題,還有很長遠的路要學習..
Charlie Ting 2015-10-25 00:21:16
Kevin Chen 所以我才想作一個能偵測供料壓力的機制,我在列印軟料時花很多時間在注意加壓臂。而且我發現只要在鬆開它之前,先施予後端線料一定壓力再鬆開。這時擠料輪那邊的壓力大,它還是會退出,但是不會造成背壓下降而使列印出變化,完全無感。 所以我的構想是使用者可以設定一個背壓上限,當它超過了就自動回轉,但並不會造成背壓不足。也不會影響到回抽的機制。進料也是正常進料。 因為兩者是獨立的,這個模組是避免失敗的保護機制而已,跟列印的部份可以完全獨立開來。
鄭政浤 2015-10-25 01:09:00
像這種保護線段的機構?(圖網路找的
Mike Chiu 2015-10-25 09:15:10

如果只是把擠出機彈簧換條磅數較小或少個幾圈,讓進料提早打滑,不知道行不行(小弟我還沒試過軟料…)

好醜......而且穩定度感覺好差
Charlie Ting 2015-10-25 12:34:05
這還是有缺點,如果雙噴或三噴,整個結構會變的很搞笑。

我倒是覺得那顆馬達很逗趣

為什麼不從拿掉回抽去思考?回抽不僅減慢列印速度太頻繁也容易卡料....
Charlie Ting 2015-10-26 10:48:46
are you sure?
汪之逸 2015-10-26 11:08:07
回抽主要是為了解決甚麼問題?可是衍生了甚麼新的問題?回抽我看起來就只是個workaround不是root cause.
Charlie Ting 2015-10-26 11:11:03
這問題我不覺得和回抽有關, 單純處理材料即可.
Lawrence Lee 2015-10-26 11:17:23
某種程度我同意拿掉回抽,有一間公司就用頂針來封閉噴嘴
Charlie Ting 2015-10-26 11:24:41
Lawrence Lee 在軟料的問題上,最大的風險來自它的材料強度不足以及軟體在計算需料量的不夠精準。問題發生在進料機構,而非噴嘴端。 若是要優化列印效果,減少溢料、牽絲,用頂針的方式是簡單有效。

同意 看完WASP 我整個忘了這是軟料討論串
汪之逸 2015-10-26 12:57:30
軟料在近端送料沒啥大問題,拿掉回抽遠端和近端送料還有差異嗎?
Charlie Ting 2015-10-26 20:22:18
大概想好結構怎麼作了,基本上還是以現成的材料來組比較省事。敬請期待~

Hello atomists :D In this case, how to get a smoother surface?
Lawrence Lee 2015-10-19 17:36:50
perhaps sharing your slicer settings would be helpful! My guess is that it does not have enough time to cool down, try printing 2 at the same time?
Charlie Ting 2015-10-20 01:22:51
In this case, your machine will prime/suck all the time, maybe try suck more than prime, such as suck 6.1 and prime 6.0
Mariel Diaz 2015-10-28 06:08:47
What about if I try to print it with Cura? Which prime/suck settings do I have to set?
