make an in-circuit programmer
2.1. Machining
I milled two ISP boards: one with the original and the other with my initial.
2.2. Stuffing
My first soldering was quite clumsy.
2.3. Programming
Arnau helped me to check the board and Ferdi helped me to program the board.
After this week, I had to mill boards almost every two weeks. I used SRM-20 and MDX-20. For me, MDX-20 running with Ubuntu is much easier and faster. However, Roland machine is not always nice to me. Almost always, there were certain problems and I had to go through them. Sometimes it took so much time.
So my advice is... Be patient with Roland! At least it does its best as you~~
Several problems that I have been stuck on:
- Fabkit v.0.3-0.4

I have been trying to mill a Fabkit several times but I failed. Our 1/64 milling bit is not as precise as it has to be, in order to mill the Fabkit. Maybe after more trials with revising the board, I will get there! - MDX-20 (Green FabLab)
You need to adjust depth with z-axis (1mm deeper would be enough). Otherwise, you might not get a nice trace cut. - “could not open port /dev/ttyUSB0” problem
If you encounter this problem, type the following command line: sudo chmod a+rwx /dev/ttyUSB0
