Hello everyone! I'm a maker from Taiwan.

嗨 大家好!我是一位來自台灣的自造者

Today let's make a cheap laser engraving.

今天,讓我們來製作一個便宜的雷射雕刻機

Step 1: What Would I Need?

以下是你所需要的材料

  1. 舊的雷射掃描機*2
  2. Arduino Uno
  3. EasyDriver v4.4
  4. ULN2003模組
  5. 雙繼電器模組
  6. RepRap 控制面板
  7. 3D列印機(我使用的機型是Delta)

All you need

  1. Old laser scanner *2
  2. Arduino Uno *1
  3. EasyDriver v4.4 *2 (to 4 control wires stepper motor)
  4. ULN2003 *1 (to control 5 wires stepper motor)
  5. Two relay module

  6. RepRap smart controller

  7. 3D printer (I use Kossel mini.)

Step 2: Circuit Test

再來我們必須先測試所有的模組是正常的。

We must first test all the modules are normal.

還順便測試了利用TXRX進行Uno和Nano通訊,以及成功傳送SD卡資訊給GRBL

Test TX RX for Uno and Nano communication, and successfully send SD card data to the GRBL.

Step 3: Make Hardware

建造整體XY軸的結構。

X軸使用的步進馬達為S35S2,因為此步進馬達為五線四相,所以我額外連接ULN2003模組以便於五線轉四線。

S35S2的線為:紅(電源輸入),黃和橘(磁芯1),黑和棕(磁芯2)

Y軸使用的步進馬達為2T424211,此布進馬達為四線,所以可以直接利用EasyDriver控制。

2T424211的線為:黃和橘(磁芯1),黑和棕(磁芯2)

在製作前先規劃製作後的樣子,Y軸以木板建立連接架構。

利用Solidworks進行建模後再進行實作。※使用電鑽設備請注意安全

The X-axis motor is S35S2. Because there are five wires, I use ULN2003 module to control it.

S35S2→Red(VCC),Yellow & Orange(coil 1),Blank & Brown(coil 2).

The Y-axis motor is 2T424211.

2T424211→Yellow & Orange (coil 1),Blank & Brown(coil 2).

Plan the production of the way, and use the board to build Y-axis.

Use the Solidworks to model.

※Please pay attention to safety.

Step 4: Cut Plane

製作木平台的過程忘記紀錄了。

使用Solidworks進行平台支撐的設計。

I forget to record the way to build the Wooden platform.

I use my 3D-printer to set the plane on the scanner.

Step 5: The Scanner Circuit

利用過去的製作的電路再加以改良,加入新的模組

在左邊擺放Arduino Nano 、Reprap Smart Controller、ULN2003,右邊擺放Arduino Uno 以及雙繼電器模組

在未來有打算雕刻電路板,所以用fritzing先行製作了電路的模樣。

Use the circuit produced by the past to be improved, adding a new module.

Arduino Nano, Reprap Smart Controller, ULN2003, Arduino Uno and dual relay modules placed on the left.

Plan to carve the circuit board so produced a circuit appearance by fritzing.

口袋雷射雕刻機(謝謝你分享一個這麼有趣的方案給大家)

I made the Pocket laser engraver before this plan.

Step 6: The Control Plane

控制面板:按鈕三個(中止、暫停、繼續),開關,12V輸入,5V輸入和輸出。

拆下舊的雷射掃描機的開關回收利用。

在製作完畢後,5V輸出的部分不小心損壞了,所以直接購買一個5V轉接頭來利用。

Control panel:three buttons (stop, pause, continue), switch, 12V input, 5V input and output.

Remove the switch of the old laser scanner to recycle.

After the production is completed, the 5V output accidentally damaged, so purchase a new one to use.

Step 7: Console

為了方便更換維修,所以風扇採用模組化設計

螢幕為方面使用而做成可活動式螢幕

In order to facilitate the replacement of maintenance, so the fan use modular design.

The screen is used as an active screen.

Step 8: Motor Repair

馬達原本的焊接線掉落,所以從新連接並修補

The original wire of the motor drops.

Step 9: Limit Switch

安裝限位開關,並且整理電線。

組完測試

Install the limit switch and arrange the wires.
Finish and test.

Step 10: Enjoy!
