オートレベリングの調整に失敗して、ビルドプレートをいきなり傷つけるという大失態はあったものの、現在は問題なく印刷できています。ラフトの上に印刷してるので傷もつきませんし。
よかった点
・オートレベリングは設定がむずかしかったが、一度設定できれば便利
・大きいことは良いことだ。
困った点
・日本語情報が少ない
1号機ENDER-3はネットにさまざまな情報がありましたが、こちらの機種は日本語の情報がかなり少なめ。とはいえオフィシャルの組み立て動画を見ながら5〜6時間で組み上げました。ENDER-3の組み立て経験がなければ、心が折れてたかも。
オートレベリングの調整の情報は全く見つけられなかったので、センサーの高さ調整とZ軸調整を根気よくやりました。
・プリントサイズは公称より少し小さめ
330×330はテーブルの大きさ。ビルドシートなどをクリップで挟んでると少し小さくなります。
・純正の消耗品が売ってない？
ノズルやビルドシートなど、純正品を売っておいて欲しい。
工夫した点
テフロンチューブが商品写真のように上手いこと上向いてたわまないので、ホームセンター金具で支柱をつくりました。
I laid everything out in their own groups, the beautifully painted frame, Z carriage pieces, gantry and hotend, power supplies, switches, a USB stick with a Micro SD card inserted, etc.
I found beautifully illustrated manual inside the box with step by step instructions, which I opened and got ready to assemble the frame. Everything is laid out in millimeters and, other than my calipers, all my measuring tools are in inches, so I had to do a lot of translating to inches to make sure I got the right pieces in the right place. When I tried to find the long parts of the frame I panicked because none of the 2020 or 2040 parts were anywhere near the length of the frame shown in the printed manual!
I finally plugged the USB drive into my laptop and opened the manual on there. FANTASTIC!! This manual had the right dimensions for MY machine. I have to believe the printed manual was for either the 400 X 400 or 500 X 500 models instead of my 330 X 330. In about an hour I was able to assemble the frame and put on the XY gantry and hotend. Be sure to slide the feet out as far as possible toward the end of the 2020 because you'll need the space to get the power supply and main board mounted when that step comes up.
XY motors were easy to figure out. Z wasn't too difficult but be aware that you will need to move the carriage to the top with the screws and snug it up, move it down a little and tighten it. If you don't do this, you'll wind up with the top bearing in the wrong place and the Z screw will be out of line, putting the Z carriage in a bind and adding extra work onto the Z motors, possibly even burning out a driver.
After mounting the heated bed, installing limit switches and wiring everything up, I was ready to try it out.
First thing I noticed was that the cable chain connection is very weak where it connects at the back. It kept coming loose and I finally had to print a support bracket for it on my other printer.
I started it and homed it, then ran the leveling routine. Wow, the machine does 16 points on the bed and does it quickly. I was worried that it did it so fast, so I ran it a second time and compared the numbers. Almost identical! NICE!!
Overall, I love this printer. I've added corner brackets for stiffness and I put OctoPrint on it but otherwise I've not changed it. I will print with it for a while and see how well it prints.
That was long winded for the only assembly issue I had, hope it helps others.
operationally the printer works very well. I wish it had open firmware but whats there is not terrible. It can be changed but will take some work. From a stock perspective, it all works fine. I printed the sample cube/cylinder demo and saw no bad behavior in the print.
I did not use the included slicers, I use Simplify3D and it worked with no issues.
So ends up I will give this one to my grandkids and build the pro version to keep for myself.
I got the kit last Monday and it was packaged really well and neatly amongst styrofoam sheets. There is an instructions manual, and its pretty decent quality. It goes through your parts list, how to get started, along with color coding what is being used on the current step. It can get a bit busy as you're progressing through, so I would also recommend going to YT and watching the video TRONXY has on this printer.
A couple things come preassembled like the motors, the hot end, rollers, and control box for the X-Axis, Extruder, and Filament sensor. Power supply and control board are preassembled as well, so the electronics are essentially plug n play.
One of my idlers for the gantry came chipped (see 3rd picture) and I was able to reach out to TRONXY's support and they are sending me a new idler. However, this is not the only OC issue I've run into. The timing belts were twisted and would not tighten, so I did have to replace them. So far the movement on the X and Y axis has been pretty stable, with a few hiccups here and there.
Z-Axis has been a hassle, while both motors are running at the same time and thankfully at the same rate. When trying to home however, the Z axis keeps moving up and thus colliding with the hotend assembly, making a god awful sound and time for everyone involved. That said, this is likely more like Operator error than it is anything on the printer's part as this is my first CoreXY style printer build.
Update 11/13 —This was entirely operator error. I did not loosen the x carriage, which caused the belts to loosen which in turn caused the printer to be unable to accurately place the x assembly where it needed to be to move. Once it was properly adjusted, I was able to print the calibration model that came on the sd card and while I did have a couple of bottom layer issues, the rest of the model printer fine.
I would definitely recommend this printer to other intermediate hobbyists, but not to beginners. I've had several 3d printers now and feel comfortable enough to be able to build one of these and get it up and running in no time, even if I have to trouble shoot for a while. That said, the instructions manual does come with some basic trouble shooting help. If that doesn't solve your issue, you could always reach out to TRONXY's support team who are super friendly and will respond within 24 hrs, not including when they have holidays.
ABL is working great so far with Z offset adjusted
You may need to team/drill 8mm holes for paint leftover on the z rods , upgrade to metal z rod bearing over plastic would be nice
Precision hex drivers are a lifesaver with this many screws for assembly
Silicone extrusion covers are excellent for cable management, cut off 1 inch strips and put over cables in the aluminum extrusion slots
そこから、操作方法を試し、調整、テストプリントで2時間で出来ました。
なかなか、良さそうな感じです。また、しばらく使い込んだら、レビューします。
注文の翌日に届きました。
プリンターは2台目で、組み立て品は初めてなのですが、休み休み5時間程で組み立て、動作確認まで出来ました。
取説は英語のみでしたが、絵が沢山で、ポイントも分かりやすく悩むことはありませんでした。
組み立て用のネジ類はかなり余計に入っていて安心できました。
少し高かったですが、10%値引きで、この造形の大きさ、z軸センサー、カラーのタッチ液晶、停電復帰などの機能を考えるとむしろ安いのかも知れません。
