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

For 2, you need to check if you connect the wrong pin on the micro switch, it should be C(Common) & NO(Normally Open), and the switch is pressed when nozzle does not touch the bed (Stay open). When touch the bed, nozzle moves and micro switch becomes close and it triggered Z Min. the Pins are labelled on the switch as well.

For 4. The always on fan always face rear. You probably put it 180 degree reversed. The two side blowers are activated by the slicer when looping and cooling. Or you can turn it on manually on control > Temperature > Fan Speed. Jog dial set it to 255 should bring the blowers to max speed.

Another need to check item for 2: You need to check the three top limiter one at a time, starting from the X (the left hand side) and then the Y (the right hand side) and finally Z (the rear one) . When in the middle, M119 should returns all open, and …… 查看更多

Excellent info Bato - thanks. The Fan Speed does control the side blowing fans OK - they start and stop as expected with Fan Speed set to 125 & 0.

I have checked the 3 top limit switches as you describe and each one does show open & closed at the correct time. I will check to see if I have the wires for the extruder limit switch reversed somewhere.

For 3, it look like your stepper connectors are plugged into the wrong sockets. (And maybe it related to 1.) in Pronterface, X should move the nozzle left/right, Y for front/back, Z for up/down. you need to check your stepper connectors are in right place.

I have checked the 4 limit switches and found nothing wrong - except Z min is always triggered. The Z min limit switch came pre-wired with 2 yellow wires leading into a plastic connector. This connector fits only one way into the yellow connector on th …… 查看更多

No, don't cut the wire and reverse it yet. You need to check the Z-min micro switch carefully, don't cut the wire yet, you need to check with the two yellow wires soldered to which pins on the micro switch, if possible, take a picture and post here for better understanding.

OK. I will have to disassemble the print head to do that - working on that now.

OK - here is a photo of the switch:

Hmm... looks fine to me, it is C and NO soldered.....

But the switch works - it just works in the opposite way it is supposed to.

I really don't understand this because I thought microswitches could only be open or closed, meaning they either short the 2 wires together, or they don't. And this should …… 查看更多

I'm going to put the print head back together now. Have you ever heard of "letting the evil spirits out"? Believe it or not, that has worked for me a few times in the past. Maybe I'll get lucky again.

Hi,Bric .Please connect your printer with Pronterface,than send M502,and send G28 ,if the problem is still there....I suggest,record a video to show what situation you got, let us to help you to solve those problem you got,thanks

OK - will post results and video as soon as I get things back together.

Make sure to upgrade your Marlin again

Yes, I did that first thing this morning. Still working on printhead re-assembly. Those sure are small fasteners!

No joy. I used Pronterface to give the 2 commands. First one worked OK; second one did the same thing as the LCD AutoHome: extruder moved to top and Y sterper went crazy. See video for the gruesome details.

OK - Facebook won't upload the video - it's 113.MB. I'll upload it to my Google drive. Here's the link for it: …… 查看更多

it look like your endstop didn't work,

or your switch broke

I don't think so - because Pronterface shows each limit switch being tripped when I activate them individually by hand.

Birk Binnard Could you check each endstops & stepper motors relation?
X axis : left stepper motor [X MAX ]
Y axis: right stepper motor [Y MAX[ …… 查看更多

After about 2 1/2 hours online with an Atom tech the following has been established:
1. Each stepper motor, when running individually, works Ok and stops OK at it's top end-stop.
2. The X & Z steppers and the Y & Z steppers function properly together a …… 查看更多

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

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.. :)

要更新升級版，不是2.0版喔

更新up2.版，也是一樣

有做過清除的動作了嘛？

側吹風扇要動要在切割軟體裏設定風扇轉速

何謂清除?

剛好我也有相同問題 你需要調整電壓 以及 韌體更新之後 需要在lcd面板 control-->RestoreFailsafe-->storememory

這樣板子才能確實執行韌體

調整晶片電壓 在升級手冊後面 有詳細圖文解說

我的板子是綠色的，調整方式要以藍色還是紅色為主

板子大家都綠色的 這邊說的是 那4塊 馬達控制晶片組 藍色 是有2顆調整電壓螺絲 紅色是 一顆 請參照 升級寶典 3用電錶 請調到此處量測～看圖

調整電壓的螺絲 很不容易找到合牙的 調整發現電壓沒動 很可能是 沒有轉動到

話說~沒用過電表><，目前有得到一顆YF-370A電表，要怎麼用? 還有測電壓時須要開機(印表機)嗎? 我是「電」的門外漢...

當然要開電源 電錶調到 圖片的擋位 測量

誤差容許好像是在 正負0.03之間

電壓正常...重灌0408升級版韌體...就可以正常使用了@@怎麼會這樣??

組好以後 加熱噴頭 進料是正常的嗎?

預熱噴頭後，按進料，也沒有做動...

那要檢查一下線有沒有插對

看版子上的進料馬達A4988有無插好，有插好話把電壓調整到4.5v. 每一個a4988電壓都要在4.5v上下～

2.0 非升級板本是搭DRV8825 Vref應該不一樣

喝~我搞錯. 但這塊需要電壓調到4.5v. 因為我調過後步進馬達就動了.

或是看這插頭有沒有掉

剛剛我把X和E的插頭對調測試了一下，這樣變成X軸馬達不做動，進料馬達是OK的~
看樣子是晶片這邊的問題
另外我的是DRV8825，電壓上和A4988有不一樣嗎@@?...不好意思，非本科系，問這樣的蠢問題...

http://hss3dp.blogspot.tw/2014/11/drv8825.html

自問自答，確定是重load韌體就ok了 看有沒有人會遇到一樣的問題可以找到這個

溫度沒上去

預熱溫度可以到兩百(PLA) 手動出料也會出來 但是直接用SD卡列印就是這樣 ~_~

切片沒設定好,
噴頭溫度沒設定, 沒看到加熱動作

借用之前解決方法eeprom restore factory default然後save
lcd menu裡應該找得到

我是用升級版，已restore failsafe再Store memory了 請問如果要設定噴頭溫度要去menu哪邊設定?切片要在哪邊設定? 謝謝

重切吧~ 看起來是檔案有問題?

楊朝舜 解決了嗎?

Mark Chen 舊的問題解決了。但新的問題來了XD.
