支撐面難免，傾斜印減少支撐才有可能漂亮

目前覺得支撐面最漂亮的是S3D切出來的

我的話，支撐面在設計時就是要準備給他難看的，水溶性高密度支撐都還不一定能達到美觀的要求如圖，這方面我也很想突破呀

熱床跟噴頭的交換看看...

好仔細的說明(^^)v

好讚～下回來試試

是剛組裝完成的嗎？以前是否發生過？

上个星期用了十次左右没问题。今天早上这样了

一年前ATom web买的，就是没时间組裝。

驅動晶片是8825嗎，請調整電壓為0.4V看看

Change new one

keong. dun rubbish here . later kena mark n kick out

Haha haha

ok. i will try to adjust the 8825 chips to 0.4volt and check again. Thanks

我有類似的狀況，是發生在剛組裝完成後，也是ㄧ直抖動的狀況。原因是Y和Z軸馬達裝在主機板上的位置反了。供你參考看看。

hi 逸文。我支前有用print几个模行，没这个问题。

今晚回去会check 晶片电压是不是0.4v

Hi all, I had did a check on the 8825 driver voltage, it is 0.4v on my multimeter. and the problem is still there. I had also updated the firmware to 2.0.7 and save the firmware. re-cycle power again to test the auto lever and home. still cannot solve the issue. The motor will rock back and forth

你先把晶片交換看看

hi 新弘, i had also did the driver chip swap. the vibration issue did not goes away . and the issue axis is still vibrating like crazy.. i will check later on micro switch, the pulley seem like ok to me. i may loosen the pulley and re-tension all axis to see if can isolate the problem. something not very right but just couldn't visually see the problem parts.

It looks like the end stop is buggy.....can you swap the end stop connector as well? It should move to other axle if the end stop is the root cause....

Hi Wang, i did suspect the end stop may have the cause of issue too. lets say i need to test the end stop, do i just swap the micro switch 2 wire JST style plugs ?

i also will try unplug the stepper motor connector n pull the belt in faster speed to check if the pulley is true. or check for any slacks in the system.

Yes, you swap the suspect with correctly working one.....2Pin JST....

That should be fine I guess....

Thank you Wang. will do it when i go home tonight. Cheers

Finger crossed for you~ Let us know what you found....

Many Thanks Wang.

There is also a command I forgot to mention, you can use it without actually home all axles, "M119" will return all endstop status. Use the command with one endstop pressed at a time and it should return "1" on the endstop you pressed. And if I am right, Y will be always 0.....

hi Wang, i just found out some issue on my printer using pronterface. when connected to software, i move all 3 axis to the top touching end stop switch and did a M119 command. its report x-max Triggered
y-max open
z-min open
z-max Triggered.

while it should be reporting as

x max triggered
y max triggered
z min open
z max triggered

i did check on the cable , it seem like it is ok. but pronterface reported there is issue.

could that be by accident i had loaded wrong marlin ?

I have seen the same problem in other printer (not atom). It was a problem with the comunication with the stepper (the wires)

hi Wang, i am guessing i may have found the culprit, i use a multimeter to do a continuation test on the micro switch.
All axis was first tested in open as this should trigger the multimeter buzzer. on the first test, Y axis triggered the buzzer, then i press on the switch, the buzzer stop. let go again, it triggered.
on 2nd switch test (Z axis) . the buzzer triggered non stop even when i press on the switches repeatedly, it does not break the circuit continuation at all. Same thing happened to the X axis. also tested on Hot End switches, when depress the hot end, the buzzer stop.
it is very strange that 2 micro switch fail at the same time....

hi Hugo. i may have found the problem. it could be the micro switch issue .

Cool, then you know where to fix....look like a electrical problem....not a big deal....

Thanks Wang and everybody for the advices. i will re-check the components and report back.

hi all, i would like to update the finding of my suspected micro switches issue, unfortunately, it is not the switch problem, i had replaced the switch and do another testing. ( this time i removed all the belt) .
x and z axis does what it should, stop the motor immediately when micro switch is press, but the y axis don't stop. it continues to spin even i had try depressing the switches multiple time...

could this be the one off stepper motor issue or ...

try use the software to test them...

Hi 俊傑, Thank you, i will try the software. Cheers

幾孔沒差.滑軌長度對了就好

別擔心, 下面很長一段都用不到, 頂住上方就好

每顆T型螺母都確實轉動九十度卡住鋁擠，也是重點。

之前有成員有文章說明了一下。看一下吧https://www.facebook.com/notes/atom-3d-printer-group/%E8%AA%AA%E6%98%8E%E6%9B%B8%E6%B2%92%E5%91%8A%E8%A8%B4%E4%BD%A0%E7%9A%84%E7%9C%89%E7%9C%89%E8%A7%92%E8%A7%92-atom-25-ex/1830772617161025/

任何切片軟體都可以嗎?

效果明顯嗎？

還不錯, 比照片上好.基本上都是要透明系列的料,否則就是得印薄殼. 聽說最適合的是PETG
