Make an circuit from David's FabISP design, but I take "FabISP" off to save time. And then,use Fab Mouulesto translate file forom *.png to *.rml.

I do it by Rolad SRM-20. Set the starting point. Load the file to star process.

It's no easy to set starting point. Opps,break knife, beacuse decline Z axis too fast.

At the same, it's difficult to let platform level keep consistent. Make many fail board.

Almost success.

Burn Program:
The sculpted circuit board with solder IC element. In accordance with the height of each element are welded elements from low to high. Don't solder SJ1. When burn firmware, use Jump to short circuit.
焊接電路板：將前面雕刻好的電路板焊接IC與元件，依高度由低至高元件分別焊接好。留下SJ1未焊接，等燒錄時再以跳線(Jump)連接短路之。

Burn Program:Using the Arduino as IC Writer. Arduino UNO pre-loadup "ArduinoISP" by Arduino IDE.
燒錄程式：我使用Arduino 作為燒錄器。Arduino UNO預先以Arduino IDE燒錄好ISP。

Arduino Reset and Gnd pin connect a 10uf capacitor.
Arduino 5V, Gnd, Pin10 ~ 13 connect to FabISP ICSP.
在Arduino ISP上Reset與Gnd接上10uf電容，並將5V,Gnd,Pin10~13接到FabISP的ICSP上。

My computer systems is windows 8.1. First set environment variables for the command prompt (cmd) having the "avrdude" command. Or install "WinAVR". It is fully with C libraries, compilers and assemblers, debugging solution as well as simulation and emulation programs.
我系統為windows 8.1，先設定環境變數，使命令提示字元(cmd)具有 Arduino IDE中的"avrdude"命令功能。或是安裝WinAVR，其中包含了C語言資料庫、編譯器、裝配、除錯等功能。同時也含有模擬程序功能。

C:\Program Files (x86)\Arduino\hardware\tools\avr\bin;
C:\Program Files (x86)\Arduino\hardware\tools\avr\etc;
C:\Program Files (x86)\Arduino\hardware\tools\avr\avr\include\util

Open cmd, command to move to the firmware folder
打開cmd，以命令移動到firmware資料夾

CD your_firmware_file_path

Burn Fuses

avrdude-q -c your_ISP_IC -P your_ISP_port -b -19200 -p t44 -U hfuse:w:0xDF:m -U |fuse:w:0xFF:m

Burn main.hex

avrdude-q -c your_ISP_IC -P your_ISP_port -b -19200 -p t44 -U flash:w:main.hex:i

The computer does not recognize the device, need to install USBasp driver.
電腦無法辨識裝置，需要安裝USBasp driver。

After download and install driver. FabISP connect to computer using the micro USB.
下載安裝後，FabISP 使用micro USB連接上電腦，即可使用。

Try to be burning by Progisp.
嘗試以Progisp進行燒錄

Production wire:Purchase connectors and cable. But local shops only sell 10 pin and 14 pin cable specifications, and therefore remove the excess wire.
製作線材：到材料行購買連接頭及排線，但當地商店只買到10 pin的規格，及14pin排線，因此需切除多餘線材。

Push cable into the connector.
將排線押入接頭

Measuring cable conduction status confirmation no short or open circuit.
量測排線導通狀況，確認沒有短路或斷路

OOPS！Wrong connector and cable direction. Image on the left cable is correct wire, I made the right one. I made both ends are all inverse. So it still could be use.
弄錯接頭與排線方向，下圖左側是正確線材；右側是我製作的線材。但我製作的兩端皆是反向，因此不影響使用，唯辨認上較不易。

Try different ways of doing USBISP and burn:
This FabISP make a USB Pin, as a result reducing a USB component on the circuit board. I use too thin FP1 . It can not successfully stuck USB slot.
嘗試做不同USBISP及燒錄方法：此FabISP直接於電路板上做出USB Pin，減少一個USB元件。嘗試做了之後發現我使用的FP1厚度不足，無法順利卡住USB插槽。

Use X Loader burn main.hex:
