ATOM 3D Printer Group 造訪社團

有幾種方式...1. 開Raft...2.膠塗多一點. 3容易翹的地方加上mouse ears....

4.印到2mm左右點快乾

目前的Raft : Type=Skirt / Inflat=10 , 要怎麼改比較好？

開brim也可.. 張到10mm

稍微翹起來也是有好處，印完輕輕ㄧ拉就拿起來了

長到10的brim很難剪....尤其有的在內圈很難處理啊.... :'(

10mm brim +1

可以拿美工小刀割掉阿~~~ XD

不過好像不好修的美...要出動溫控烙鐵了嗎?

所以我不愛開Brim....我喜歡老鼠耳朵....然後連接處給他畫的很薄, 印好以後用手折就折的下來了

我有時後會連底都跟著耳朵折下一小角..XD

所以耳朵不要畫太厚啊, 而且耳朵太厚的也容易翹.....

新手追問一下 老鼠耳朵大概是怎樣弄阿？ 我也正在研究怎樣讓大面積的物品邊腳不要翹起

我耳朵+牆角... XD

耳朵要夠大才有效.....XD

果然..難怪當時我預到一些狀況還是會翹...
就跟Brim開10mm一樣的道理...
Bato Wang 你耳朵通常厚度抓多薄?

最常用的厚度是0.6~1.2mm看東西...重點不是厚度而是面積

btw: 我的耳朵經常是半徑20mm的....

根本就是Brim開到20mm等效了.... 難怪都不翹...
/me 已經滾去玩60度熱床了

自己的Brim自己畫....哈....

太薄會被翹起來的角給拉破耳朵 XDDD

重點要自己畫耳朵, 用 slicer 生成的 brim, 擠出時都是跟角一樣形狀, 強度不夠

自己畫的, slicer 會用 45 度去填滿, 強度會高很多.

看來要來弄plugin不過kisslicer比較沒plugin架構

這一招... 聰明耶 XD

趕快出ATOM熱床套件比較讚..^^

也可以用 Kapton, 高溫雙面膠帶

關側吹風扇，降速度，還有手動熱床-吹風機，可以事先預防，邊吹邊打，或是當做事後藥，當發現開始翹的時候，可以用吹風機熱風吹一下，然後壓回去。

軟了才能壓, 不然會整片翹起來就GG了 XD

朝左

或朝右...

謝謝 也就是說兩邊都可以

朝側邊。說明書沒有明講，害我最後得把馬達全部拆下重裝，不然玻璃上不了…

失步之後造成噴頭座跟物件相撞，降速&調整一下皮帶鬆緊，太緊太鬆都會失步

馬達失步，請降低列印速度

OKOK~我調整看看~@@...要不然這樣越印越歪~有點冏

往哪個方向偏就是那個方向的那一軸有問題 檢查一下事不是同步輪沒鎖緊

剛剛看了皮帶~有一條特別鬆~重新調整後~在出發~

The gcode not correct? looks like moving out of the printable area.
Did you tried the test files ?

降速，降溫，應該就可以解決

如果是用360度起點跟終點，這現象是正常的，你如果單一起點還有這個現象才有問題！

對。是用360度

360度 那欄會隨易散佈每層列印的起始點跟終點，所以會造成這種情況喔，可以調0試試看

不建議調成0度，之前1.0版時發生過熱堆積

Hi Birk, please do a factory reset after you upgrade your firmware. prepare->restore failsafe->store memory. And if you want to check endstop value, you can use "M119", it will return the endstop value.

Hi Birk. It seems that your microswitches didnt work well, First you have to do what Bato said, prepare ->restore failsafe -> store memory.
Shawn just sent you an attachment named "Mastering Atom 2", you can check how to use pronterface to check your machine's state, Its on page 10 and page11. (y)

Thanks but - my Prepare menu options do not have a Restore Failsafe option. The last one listed is Move Axis.

Perhaps the firmware I loaded was not the correct one. I'm checking on how to do the Pronterface checks now.

Hmm...if you don't have it in prepare, check it under "control"....if you want to do it in Pronterface, it is much easier....M502 -> M500 will do the job...

hmm looks like should be in Control ->

You are correct - I found it there. But pushing the control knob on it does not bring up another set of menus. So I did Restore Failsafe followed by Store Memory, but that didn't seem to have any effect either.

I'll go get Pronterface and see what I can do with that.

Well, Pronterface gets an error trying to connect to the printer. I set Pronterface for COM1 @ 250000 and hit Connect but it gave a bunch of error messages ending with "Cannot configure port, some setting is wrong."

this is not surprising because I do not see the printer in Device Manager. What I do see is UCB Serial Converter listed under Universal Serial Bus, but that's all.

OK - turns out the printer is on COM3. So now I can connect to it.

I think I found the problem (or at least a proble). I clicked the Pronterface Home button and the X slider moved to the top and stopped, but when the Y slicer did that the machine started vibrating. So it's pretty clear there is something wring with the Y limit switch.

Try to Move your carriers to the middle, use M119 to print out endstop value, and manually press them one at a time and use M119 to see if they returned ok...you probably will see a axis always return open...and that should be the problem

Well, this is very interesting.

WIth it's power off I manually moved the extruder to the middle of the print space. THen by hand I closed each of the limit switches and ran an m113 from Pronterface. Each time I got the desired response - y_max triggered, z_max triggered, x_max triggered.

So the vertincal limit switches are working OK.

I tried tripping the extruder's limit switch but the m119 command returned with all endstops open. So I may have a problem with the z_min switch in the extruder - but even if I do this should not bother the Home function, should it?

I used Pronterface to set extruder heat = 185C and it reached that temp quite quickly. I checked the temp in the Atom2 LCD and that also said 185C. SO it's good to know that part works OK.

Pronterface moves the extruder as expected by clicking it's X, Y, and Z buttons. So I am still quite confused about what is wrong with the printer.

Perhaps you should try re-uploading the firmware to the mainboard
https://www.facebook.com/....../%5BFirmware%5D%20atom2.0.rar

or you should recheck the position of limit switch on control board.

Thanks. I will install new (ver. 3) firmware in the morning and check the connections of all 4 limit switches.

sometimes it could just be the endstop being in the wrong socket, when it homes it always look for X axis endstop first, that can explain one of the carrier hitting top of column violently. Because it's triggering the wrong endstop.

I got the latest firmware uploaded OK. I checked the Extruder head micro-switch and it turns out I had the adjusting screw turned in too much. So I backed it off allowing the limit switch to open. Ialso checked the connections for each of the 4 limit switches - they all look OK.

Now, when I run the m119 command I get x, y, and z max opened and z min triggered. If I manually close the z min limit switch I get z min opened.

This seems backwards - but is it?

I am going to start a new message thread that begins with my current status.

Sounds good, Let us focus on your homing issue first.. :)

Check the files area in this group, find the ATOM2.0.rar

Thanks - I got that and expanded it OK. But what piece of software actually loads the firmware into the Atom2?

Never mind - I figured it out. There is a Marlin.ino file in the Marlin directory that Arduino was able to upload to my Atom2. Now my machine is functional again. Thanks for the pointer to the file.

Good question. I never used either piece.

on the wires touching the end of extrusion. it act as a protection layer against the sharp edges

換個角度

厲害＠＠ 不過我是還在挑戰列印女角裸體 ＝＝＋

試問機器從組裝好到現在有休息過嗎？產出也太驚人了吧

有阿, 昨天跟今天 XD
