昨夜印了小魔艾(50mm高), 無支撐, 中間還是無法平整, 分層明顯, 且懸空處疙瘩嚴重, 請問是切片設定可以改善, 還是硬體哪裡出了問題? 謝謝

Can't seem to get good layers on small prints where the layer is not a continuous movement. Extrusion seems to be erratic on these layers, but perfectly fine on the other parts

For medium and larger prints, there seems to be no issue at all.

Are all these models printed in one time?

It seems that cooling time isnt enough, that's why when mall feature was printed, it deformed from time to time.

Zhao Soh

3 individual prints, starting from the left most one first

Peter Wu

You can try enable Prime pillar function which is in Support column. After finishing path it will print a pillar next to model, makes it easy to cool your model.

請問大家用用電腦畫出來的圖面跟印出來的尺寸,差多少啊?因為我怎麼印都跟圖面尺寸差1mm

洪瑞宏
2015-05-12 10:46:26

我也差不多,但是我有inset 0.15,這樣我孔才會準。我只重視孔。我是atom 1.0

Kean Tsai
2015-05-12 10:52:30

我也是1.0,我是要開衛浴設備的模具要用⋯所以要蠻準的。不知道有沒有高手可以解決這件事⋯

洪瑞宏
2015-05-12 11:18:30

說真的,我常常要組車用的樣品,一定是跑CNC樣品,工業級RP也不夠準!

Kean Tsai
2015-05-12 11:25:32

我目前解決的辦法是看印出來尺寸少多少,在去做調整。

Clarence Lee
2015-05-12 11:25:41

內孔被擠太多不好算...沒法1:1產生成品..孔越小可能越嚴重
這要靠切片軟體的智慧
不過目前可能沒有很會處理這個的切片軟體?
以前的skeinforge據說弄得還不錯

皮帶跟無背隙滾珠螺桿是很大的差異,更何況CNC有光學尺回饋,步進馬達跟伺服馬達也不是一個層次,控制器幾十萬級跟千元級。我建議還是把3dp用在它可以發揮的地方,要機器做它做不到的事,有時候是多浪費時間。

Kean Tsai

真的!!!
但我覺得好用的地方在跟廠商交涉平面圖的時候可以縮短溝通的時間。

Mike Chiu

1.0 +1 不過還是不太清楚為何outer perimeter first 尺寸可以較準一點?

YF Lin
2015-05-15 08:17:18

我是預訂目前還沒有機器,只是有台舊型的FDM,我自己是買手工鉸刀來鉸孔,除了尺寸也兼顧表面粗糙度。

These settings seem to work pretty well. Previously I had set de-string to 8-8-3 and that resulted in quite a few internal strings. Next I'll try layer thickness = 0.2 and see if there is a noticeable difference.

Flow Adjust looks not normal, the Max value should not be so big .
I would set it to around 8.( but for current select speed is not a problem. It's just a constraint to limit the max speed.

Birk Binnard
2015-05-12 01:14:43

Thanks, but do you mean I should change 100 to 8?

I've been experimenting with different speed settings but haven't yet decided on which best.

Have anyone experienced that the ball heads becomes rough on the surface?

To test if your ball heads has become rough please try and turn the carbon fiber rods when in place. If you hear a grinding sound like sandpaper. Then the chrome on your ball heads is starting to loosen.

After 300+ hours of printing I refurbished the finish on all of the ball heads. Now after 500+ hours everything works like a charm. No grinding sounds and much, much better, smoother and more precise motion. It now runs better than it did to start with.

Also use a white PTFE (teflon) synthetic grease on the ball heads inatead of the stuff supplied in the kit. PTFE lubricates the best possible way in this type of aplication. The white color makes it easy to know when to change the grease on every individual ball head. It is time to change when white turns dark grey.

Even better would be to not have to use any grease on the ball heads, but. This is a matter of matching the right materials. That is another discussion.

Here is a picture of how my ball heads looked before and after refurbishment.

Harry Cayne
2015-08-20 00:19:20

how did you do the rechromig (galvanising)?

André Medborg
2015-08-20 02:26:06

Hi Harry Cayne i placed one ball head at a time in a hand drill and used grit 1200 sandpaper to remove the old chrome. Then i polished it with two kinds of wax based polish. That was it. It really works well still after lots and lots of printing. I also use a small amount of teflon grease on the heads.

Harry Cayne
2015-08-20 02:32:25

ah ok thanks, so you made a nice polishing there no electroplating involved

Harry Cayne
2015-08-20 02:34:18

by the way what software are you using ?

Harry Cayne
2015-08-20 02:34:45

for 3D printing ?

André Medborg
2015-08-20 02:45:18

I mainly use Kisslicer and Slic3r, but I have started using CraftWare again and it really works very well. Kiss is very allround and works well. Slic3r is very good for making seamless single walled objects like vases etc.

André Medborg
2015-08-20 02:46:06

Did you have problems with the ball head finish?

Harry Cayne
2015-08-20 02:48:30

no not yet I'm a brand new user, but I've just realised that Craftware is hungarian and I am hungarian so I would be happy if this would be a useful software for us !

Harry Cayne
2015-08-20 02:49:47

nice to hear that you are using Craftware too

André Medborg
2015-08-20 02:50:14

Ha, that is funny. Go Hungary!

花了一個周末印了一隻大隻的機器人,沒想到周一回來後就看到這個悲劇的成果,中間少印了好幾層,牽絲的問題也有點嚴重,不知道有沒有人知道該從哪個地方改進?
附圖是我的參數和悲劇的成果...

劉義瑋
2015-05-11 17:31:49

支架也有點難差,GAP是不是應該要調大一點比較好?

廖新弘

這個不用支撐也可以印,1.0版時我有印過

Jeff Lin

填充設的太小,層高0.1是個問題,最大的問題是Z-Lift=0

Suggesstion for Atom2 firmware change:

If a print job is stopped or paused by an LCD command, the printer leaves a blob of melted filament at the point where the extruder stopped. It would be nice if this did not happen.

Could this be stopped by having the firmware insert a Retract function immediately after a Stop or Pause command?

If Yes is the answer, then the Resume command would need a corresponding Feed (or whatever it is) command added so the filament could begin being extruded when the printer restarts.

0.2 (orange) VS 0.3 mm (brown) layer height. I'll be using 0.2 from now on - even if it does take longer to print.

0.3 mm Looks like ATOM1.0's layers high 0.15mm

André Medborg
2015-05-11 16:33:08

Your printer should be able to print very nicely at 0.3 . Something else is wrong. I have been experimenting with 0.4 and 0.5 and they work fine too, all though speed has be reduced correspondenly. I found that 0.3 prints faster and better than 0.5. Th e Atom2.0's ability to melt larger amounts of fillament fast is not very high. This puts a limit on speed in thicker layers. And no it does not help to increase temperatur.

Birk Binnard
2015-05-11 22:27:05

Andre - I am beginning to suspect you are correct. I just printed a part at 0.2 layer thickness and it does not look nearly as good as one I printed a few days ago. I do not understand why this is happening.

I noticed that Kisslicer has the ability t o choose from 2 different Style Models (Small Models and Normal Models) but it is not clear what these mean. I'm going to make a test part that is just a small cylinder and try different settings to see if I can identify why my layers look so rough.

Andrew Lee

We've actually used two ceramic heating plates before on the hotend and it helped quite a bit for high flow rate situations

Andrew Lee
2015-05-12 14:04:55

Every single type and colour of filament has its own melting and string characteristics. Even a 5 degrees change of temperature can improve the outcome.

The preset kisslicer styles are just preset values of those settings you see, there should be no internal hidden setting or feature that are tied to the presets

André Medborg
2015-05-12 14:13:09

Andrew Lee how come you only use one ceramic heating plate now? I cant imagine the price being the issue.

Andrew Lee
2015-05-12 14:16:28

one plate is sufficient for general use

Andrew Lee
2015-05-12 14:41:18

our engineer has added that it uses more power (wiring will have to be carefully done to prevent overheating and overcurrent), PID settings have to be tuned, temperature harder to stabilize.

you could just get a bigger / more powerful heating plate for your use, after all the ATOM is pretty customizable. we've just been using two plates cause it's more convenient

請問2.0電路板上剩餘的PIN作用為何?Marlin是否都有功能支援?例如溫床的加熱器與溫度偵測。另外如果想把開機時就一直運轉的後吹風扇改成噴頭加熱時才啟動,是否有類似側吹風扇的電源控制端可以使用呢?
