若覺得發條鐘太難印，可以先練習印發條車 ~ -_- "

以下為我印的車子 ~
輪軸要縮一下才會順，輪胎本來要加軟料，沒想到軟料這麼難連 Brim都印不出來，只好放棄輪胎任他甩尾

發條使用明燿PETG試用線，較一般料有彈性較不剛硬，否則發條會一次送完，暴衝 ~

[抗牽絲，改機想法]
PS:目前快接頭上已經裝了墊片

最近清理牽絲弄得有點煩，想要看看能否那個地方改裝一下解決這個問題，以下是爬文後的幾個思考方向，請先進指教：

(1)改成進端供料：類似WASP那樣的作法，擠出機在噴嘴上方，藉由縮短擠出機與噴嘴的距離來讓實際的回抽與設定值接近。這個方案社團內已經有人實做出來了，不知效果如何。不過對我來說技術太高，即使有用我也做不出來，只能放棄。

(2)把擠出機從機架上方改到玻璃圓盤上方18CM處：這個位置與噴嘴及玻璃等距，也有縮短距離的效果，應該可以把鐵氟龍管從原來的100CM減少到40-50CM，只是不知效果如何，但是技術不高，是我可以做的到的程度。

(3)把供料的鐵氟龍管改成3X2的：觀察發現，目前的4X2鐵氟龍管內部與PLA線料還有許多空隙，有人認為這個空隙會造成線料在噴嘴遇到阻力時有變形的空間，所以我想若是把給料管改成3X2的，會不會讓回抽與給料效果更好，因為3X2鐵氟龍管內徑剛好比1.75MM PLA線料大一點，幾乎沒有容納變形的空間了。這項改裝也沒有什麼技術問題，可以做的到。

(4)結合做的到的第二與第三方案，看看效果是否有更好。

以上是剛剛想到的，請各位指教。

他是不是把Z-lift設定的很小，加快XY-Travel速度？

Vincent LM Yeh
2016-01-22 19:31:18

之前怕噴嘴撞到列印件所以都把Z-lift設高一點(0.3mm)，也許這反而讓噴嘴上抬時拉出一些料，讓牽絲變多。

我先前印的GYRO是設定Z-LIFT＝0.3mm, 目前改為0.1mm重印一次，看看改善程度如何。Z-LIFT若為0感覺風險滿高的。

LED Lamp

This is my latest print using my new/replacement hotend. It is a LED table lamp that uses a remote controlled LED that can change colors and turn on and off.

Photo #1 is the finished print on the printer. Photo #2 shows the lamp by itself in normal light. Photos #3 & 4 show the lamps's excellent detail - I sliced it with Craftware and there were no blobs, seams, strings, or hairs. Photo @5 is the lamp and the LED unit with it's remote control. Here is a video of the lamp in operation:

Replacement hotend (and some questions)

My replacement hotend arrived today and I am printing with it right now. So far everything looks good, but I am just a few minutes into a 22 hour print, so hopefully everything will finish OK.

A friend of mine who has been doing 3D printing for more than 2 years told me he had nozzle clogging problems similar to the ones I experienced, and his group of printer friends told him that the PTFE tube inside hot ends needs to be replaced about every 6 months or so. Now my friend has a cartesian-type printer, but I don't know if this would make a difference with hotend internals.

So my question is - does it make sense to replace the PTFE tube in the hotend on a regular basis? And if so, how often to do it? In my case I replaced the PTFE tube several times and still had nozzle jams - and I have never determined that actual cause for these jams. (Would someone like to examine my jammed hotend to see what they can determine??)

So I wonder if regularly changing the hotend PTFE tube is a good idea - or not.

PID Values gone wacky?

I recently had to change my printer's thermistor, after which you are supposed to update the printer's PID values because, apparently, different thermistors behave somewhat differently. Well, I did not do that, and then I noticed my hotend temperatures were deviating quite a lot from the specified value. "Quite a lot" means up to 20 degrees.

Well needless to say this caused all sorts of extrusion problems, so I figured I better do the PID reset. I followed the steps on the Atom2 website and ended up with these values: Kp = 30.90, Ki = 2.79, and Kd = 93.32.

I used the LCD panel to enter these values and then did a Store Memory/Load Memory. So I think I got the new values saved OK. I did notice that the new values were quite a bit different from the ones previously in the firmware.

Now my printer is printing and doing a great job with extrusion. But the LCD says the temperature is 166/200. This can't be true because at 166 my PLA filament would be completely solid. But the extruder is working fine and the layers look great.

In the time I have typed this the LCD has changed to 177/200. So I must have messed something up - but what?

PS: Now the LCD says 167/200 - but printing looks A-OK.

Edit: After about 12 minutes the hotend jammed and the extruder was not able to feed filament. So my guess is there is something messed up with the temperature control.

Edit 2: I hooked the printer up to Simplify3D's Machine Control Panel and watched the temperature plot as I tried different values for the hotend temperature. All of the plots looked good - I changed temps from hotter to colder and back again and the indicated temp always hit the specified value right on - and held it. Moreover, the LCD display also indicated the correct temperature and was in agreement with the temperature plot.

So I started my actual print again and (again) it seems to be going ok. But the LCD says 167/200 right now.

Most confusing indeed.
