Selected png image of PCB and fab module has detected size of board based on image size. Image size detected as 21.336 x 45.234 mm
Selecting output type as .rml
Based on machine I selected .rml as output file
Selecting machine as MDX-40
Selecting PCB traces as 1/64
Settings that worked in fab modules
| Machine : | MDX-40 |
| Speed : | 2 mm/second |
| X0, Y0, Z0 : | 10, 10, 0 |
| zjog : | 2 mm/second
I have kept this same as cutting speed. This is to avoid jerks while axis movements
|
| RPM : | 4500 Revolutions per minute |
| Other settings are kept default | |

PCB milling progress
Learnings while PCB Milling
- Initially kept cutting speed at 4 mm/second but milling cutter broke with that speed. Hence I reduced speed to 2 mm/second and thereafter it worked
Doing trial soldering
Trial solders
PCB Soldering Start
PCB Soldering Finished
Learnings while PCB Soldering
- Flux makes important role here while doing PCB soldering. I have applied flux over all surfaces where I want my solder to stick. Flux makes solder to stick properly
- Twice while doing soldering I did put extra solder over controller leads causing pins short. I have tried to remove solder using hot soldering Iron but its made possible when I used extra flux at iron. Hence if you want to remove solder then put extra flux over soldering iron
- Controller and USB was toughest part of soldering. I have ground soldering iron with sharp point. Then took sufficient solder and applied flux over pins. Then with capillary action solder applied successfully
Flux plays key role. Use it appropriately
Programming of Fab ISP
I have downloaded FabISP firmware from fabacademy archive. Here is a link Download Firmware from here
Though its for mac but can be used on ubuntu also
To know how to run make file use following command
sudarshan@sudarshan-Lenovo-ideapad-100-15IBD:~/Desktop/New/firmware/fabISP_mac.0.8.2_firmware$ make help This Makefile has no default rule. Use one of the following: make hex ....... to build main.hex make program ... to flash fuses and firmware make fuse ...... to flash the fuses make flash ..... to flash the firmware (use this on metaboard) make clean ..... to delete objects and hex file sudarshan@sudarshan-Lenovo-ideapad-100-15IBD:~/Desktop/New/firmware/fabISP_mac.0.8.2_firmware$
To build make file use make hex command. It gave an error

This error is because of avr-gcc drivers were not installed.
Drivers are installed for linux as follows
Use following command to install avr-gcc drivers for linux

To burn program using arduino change line no 16 of make file
AVRDUDE = avrdude -cavrisp2stk500v1 -b19200 -Pusb/dev/tty.usbmodem1411 -p $(DEVICE) # edit this line for your programmer
Now you can use Arduino as a programmer
Making Arduino as ISP
Connect arduino to computer using USB Cable
Open Arduino IDE and select settings as mentioned
Select Tools -> Board -> Arduino/Gennuino Uno
Port -> /dev/ttyACM0 (Arduino/Genuino Uno)
Programmer -> Arduino as ISP
Select Arduino sketch and upload
Select File -> Examples -> ArduinoISP -> ArduinoISP
Click on Upload 
Note down pin numbers. Preferably put it in spreadsheet
| RESET | 10 | Yellow |
| PIN_MOSI | 11 | Black |
| PIN_MISO | 12 | Blue |
| PIN_SCK | 13 | Brown |
Arduino is now programmed as ISP
Unplug Arduino
Download and install ATtiny board libraries
Without which ATtiny boards will not be visible under Tools -> Board
Set board manager Url
Open Arduino IDE and click on File -> Preferences
Set Additional Boards Manager Urls as
https://raw.githubusercontent.com/damellis/ATtiny/ide-1.6.x-boards-manager/package_damellis_ATtiny_index.json
Download and install boards from Board Manager
From Arduino IDE open Tools -> Boards -> Board Manager
Search for ATtiny. It will show up ATtiny Library
Select version and click on install
It will download and install required libraries
Check under Tools -> Board -> ATtiny Microcontrollers
Connect FabISP to Arduino
Connection points
| Color | Arduino | FabISP |
|---|---|---|
| Blue | Pin 12 | MISO |
| Yellow | Pin 10 | RESET |
| Green | Ground (GND) | GND |
| Brown | Pin 13 | SCK |
| Red | VCC (5V) | VCC |
| Black | Pin 11 | MOSI |
It is recommanded to use color coding for connections. But its your choice. You can use all same wires for all connections. Using color coding makes it easy to reconnect again if required
Use capacitor and connect between Ground and reset pins of arduino. This is to ensure that arduino ISP program remains inside Arduino
Connect Fab ISP header with arduino
Burn firmware to FabISP
make hex ....... to build main.hex make program ... to flash fuses and firmware make fuse ...... to flash the fuses make flash ..... to flash the firmware
This has burned firmware to FabISP successfully
Used FabISP to program ultrasonic board
I have used fabISP for programming my ultrasonic board which I have used in my final project.
