ATOM 3D Printer Group 造訪社團

我以為是酒桶。。。

3 in 球閥把手

鑄鐵斷了

林于翔 上吧!!

賣掉了？

鋼鐵人之金鋼飛拳 XD

大概是支架不穩 噴頭撞歪 部份炒米粉

支撐的密度要提高。

手那邊出問題XD

支撐不夠穩，作手的時候物件會跟著噴嘴晃動。

牽絲太少的缺點~~~

回抽 速度

分開印比較好

圖檔有破面才會這樣、你這個是不是抓SketchUp 裡面的圖印的

Thingiverse

鋼鐵人的顏色不對

這個是針對驅動是DRV8825 本身的缺陷才有用

I am using it, it really helps you can print with faster speeds!

Here's my blog page on this issue: http://birkbinnard.com/....../smoothing-stepper-motor....../

Bottom line: not needed on Atom 2

皮帶巡一下,可以的話除了原廠固定方式再加尼龍束帶比較OK！

你有列印中加速嗎

撞到列印物？

速度太快撞到絲狀物會跑掉

應該是底下翹起來,你檢查一下,最近比較冷,印大物件的時候底下翹起來結果上面撞到所以錯位,建議你速度調慢一點,讓他每一層冷卻時間變長,不會有收縮

位移可以看這篇： https://atom3dp.squarespace.com/printing-problems/#head6

皮帶的話，其實要滿鬆的喔，不能是緊的狀態。撥起來的頻率45~55hz就好，三軸要一樣

Try this first.

Ah yes, I completely forgot about the PID settings. I have done that before and I know it takes a while.

Unfortunately neither Pronterface nor Simplify3D want to connect to the printer - the connection sends back garbage characters and I get messages like "could be invalid baud rate" and "connection failed". So I'l have to fgure otu what's going on with that first.

I just delete m109 in my g-code and start printing.
And newest firmware is 2.5.

2.5? Where does that come from? I got 2.0.7 from the Atom website. Is there a better place to find it?

And if you delete M109 how does the printer know to not print with a cold hotend?

You can use this on 2.0

You just reach temperature and start printing

Thanks for your suggestions; I have some interesting results:
1. Firmware 2.5 did not work for me. I installed it OK and took out the M109 command. When I started the print the printhead started printing about 2 inches above the print bed and the hote nd was not at the proper temperature. No filament was extruded from the hotend.
2. I added an M104 to set the temperature to 215 and then tried to run an AutoLevel (which I had run OK before with 2.0.7), but the printer made a loud buzzing sound and didn't do anything. I took this as my clue to revert to 2.0.7.
3. I reinstalled 2.0.7, performed an AutoLevel , removed the M109, and verified there was an M104 S0215. When the printer started printing no filament came out. The LCD said the temp was something like 67. I took this to mean the hotend had not yet got up to the 215 temp.
4. I restarted the printer and did a warmup to 200. When I started the print this time it did in fact start printing - which it is doing now. I'm printing a string test part and using the same slicer settings I've used in the past the print is showing much more stringing. But it is printing the layers at 185.
5. I don't understand why Arduino can talk to the printer OK, but not Pronterface or Simplify3D.
6. I thought I could use the printer LCD to set PID values by hand, but I looked in the Configuration.h file and there are no defaults there for Atom2. I didn't think it wold be wise to use values from a different printer.

I resolved the serial port connection problem by setting S3D & Pronterface to use a baud rate of 250,000 and the Serial Port driver to a baud rate of 460,000. I have no idea why this solved the connection problem, but it did.

I ran the PID test and go t numbers KP: 17.63, Ki: 1.27, Kd: 61.25. The first 2 were fairly close to what the printer's LCD screen showed, but the last one was far different. At any rate, I stored the updates and did a preheat 200.

I was disappointed to see that the printer could not get the hotend to a temp higher than about 190. But I ran my string test print again, removing the M109 line since I knew the printer could never get to 215.

The print failed shortly after it started with what appears to be a jammed nozzle. I'm thinking the problem may be that the hotend I'm using has a heatsink just above the nozzle (it's like the original Atom 2,0 hotend assembly) and this may be preventing the heater disk from getting the hotend up to desired temperature. So I may go back to using my "newer" hotend which is similar to the current 2.5EX one.

Edit: Yup - if I stop the heatsink fan from running the hotend gets up to 200 quite quickly. Letting the fan go results in the temp goes back down to around 190. Looks like I really will go back to my previous hotend configuration.

Hi! I have had the same issues as you with the 2.0.7 firmware. The temperature fluctuated all time, so I went back to the 2.0.6 firmware

I am going back to 2.06 also because 2.07 does not allow negative Z-Offset values.

2.06 working fine - no need to redo PID values.

i also have problem on heating today, i found out my heater's wire snap.

不用改jumpers 要看馬琳這行數值是不是#define DEFAULT_AXIS_STEPS_PER_UNIT {160, 160, 160, 200}

我的现在是这样的数值，如果换了8825后要改成什么数值。

你的不是ATOM機器，但是應該理論是一樣，你試試看那個數值乘上二倍

擋風片有裝好嗎？調看看PID？
