ATOM 3D Printer Group 造訪社團 » LCD

We have connected the atom to my computer but it doesn´t recognize the device (so it does not install the driver, so we can´t controll the printer)

After checking those connectors's positions Besure to Upgrade the right Atom 2.0's firmware to your board.

Thank you! its working now ;)

but i had to install the FT232R USB UART driver for connecting the printer to my computer ;)

keep going!&keep posting your progression

Fan/cool
這欄就是....
目前設定的意思是0.15層高開始全速吹

是阿~可是它就是不動>_<

LCD 就是從 Temperature 那邊進入, 把 Fan 調整成 255 就是全速.

Is there a photo about the fall off "magnetic bearings"?
Another photo needed for the controller board.
Is it still accessible via Pronterface?

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.. :)

有照片嗎？可以po看看大家幫忙抓。建議先把所有的 8825 driver 拔下來，板子再通電一次試試看，通常這個狀況有可能是某顆 driver 短路燒掉的情況..

囧我全拆就好了 我現在一個個放回去

阿糟糕 有人知道有散熱片那邊應該是要靠四個端子的黑線嗎？ 還是反過來我拆太快orz

爬了一下文 我發現的確是散熱片在下 但是以下附上我拆到一半的圖 因為xy居然是一上一下的，所以我整個不知道到底哪個是對的.......目前確定有一個8825（本來在z軸上的，他原來裝的是正確或是相反我也不確定）好像會導致他整個板子燈不亮 該如何是好？ 謝謝:)

我應該知道問題在哪了，應該是昨天裝好之後沒有check是不是所有晶片的位置都在對的地方（我以為這不用注意..orz） 上面那張圖可以看到x是反的，所以應該是x反導致他燒掉？ 我之後說是z純粹是因為我拆完都放在一起，剛好把原來x的放到z，以為是z的壞掉，應該是這樣。

所以全部裝回去正確的方向後板子可以動嗎？我們還不確定他有沒有燒掉

沒辦法有一個會讓整個板子無法啟動

目前就是先把那一個移掉 至少先測xyz這樣 （有問題的那個我猜是原來x上面裝反的那個晶片？）

如果不嫌棄小弟手拙、也可以幫你義診一下、你應該在北部吧？

樓上大大感謝<(_ _)> 我在南港昆陽站附近 其實不是很方便到的地方 如果8825壞了外面直接買買的到嗎？

我可以直接計程車移動機器到您那邊？
