我有接章魚哥喔

接上去目前沒遇到什麼問題

Astrobox呢，有沒有人比較過他和章魚哥哪個好玩？

Astrobox比較不用花腦筋
但Octopi比較好玩

原始 G-Code 是用 S3D Vase Mode 產生的，也已經關掉 G92 E0，但是 Velocity Painting 0.54 運算之後，還是會產生接縫拉鏈，有空再研究一下 G-Code 檔裡面為麼還是會有換層的頓點。

cura_la0.2_t0.4_speed30，謝謝Morgan Chang的詳細教學…

不好意思，我是用Cura做切片，用Velocity Painting 運算後一直跑出有問題，不好意思能幫我看看嗎? 感謝您

媲美下哈哈

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

昨天有試，弄不出來！

我還沒有試，看看有沒有人可以分享經驗

https://www.velocitypainting.xyz/blog/

有下載他的程式了，但研究不出來！

因為回文無法一次說清楚，另開一了一篇說明，若有錯誤的地方也請指正 https://www.facebook.com/groups/atom3dp/permalink/1897428213828798/

這個G-Code範例檔別放在ATOM上面跑，噴頭會衝出範圍，只適合放在笛卡兒座標的機器上面。

Repetier新版也有不少功能，是有比馬林瘦一點，運算結果也有一些差異，反正用不習慣就再刷回原廠韌體就好了，只是刷韌體造成機器有問題的責任歸屬比較麻煩，不然Repetier有網頁可以直接線上設定韌體參數也不算太難

層高變小，噴頭的溫度跟列印速度也要跟著變小

列印方向有問題

印0.05，吹工件散熱要加強
