i started by going to downloading the "traces" and "interior" pngs for hello.ISP.44.res from the class assignment page for this week. I then went to fabmodules and loaded the traces, and created the toolpath for the Roland Modela.
there was already a large piece of FR1 pcb on loaded in the machine, that had some cut-outs but alot of unused space. before sending the job, i measured along the x-axis to start my job (100, 20). jogged the machine over to the place i wanted to start, and lowered and zeroed the 1/64 in. endmill. i zeroed the endmill again in a spot that was more in the upper left corner of where my board would have a corner with trqces towards the edge because because the first time i began to mill in that area it seemed to barely scratch the surface, although milling towards the front.
after brushing off the dust, i switched bits to the 1/32 in. zeroed it in the same starting spot, and loaded the interior png, created the path and sent the job. it cut easily, and popped out, however it was very close to the outtermost trace, and so i tested that trace with the voltmeter before continuing.
next i washed and dried the board, and began picking out the components and soldering. after soldering, i tested each solder joint with its corresponding trace, and where there seemed a potential for accidentally creating an unwanted solder bridge (like across the mini-USB) i checked to make sure that things that were NOT supposed to be touching were in fact NOT touching. everything checked out.
i am a returning student. last year was my first time milling, soldering, or prgramming anything, and i made this video on the mechanical process of making the board. this time around, it was MUCH easier.
now on to programming...
this year i began to make a video of me successfully doing the programming... after 2 days of trying- it didn't work successfully. i was able to $ make clean and $ make hex, but when it came to the next command $sudo make fuse- it refused. i tried it with both programmers, and got the same error message.
i googled the error message that i got "avrdude: usbdev_open(): did not find any USB device 'usb'" i looked back at old fab academy sites, and realized it was not recognizing my board. i tested all connections with the multi meter, and then replaced my attiny44a microcontroller, and then tried again, and got this error message:
avrdude: usb_open(): cannot read serial number "error sending control message: Operation not permitted"
so on the following day, i just milled and stuffed another FabISP, followed the steps from this tutorial in the fabacademy archive to program it. and it was successful!
$ make clean
$ make hex
$ sudo make fuse
$ sudo make program
$lsusb and the computer recognized my FabISP!
