I am very new at this and am doing research on what type of machine I would like to design. For starters I contacted a company that fixes plotters and was able to get a hold of several old heads that were to be junked and harvested the linear bearing, gears, motors, ect. I think I would like to copy how they controlled the machine which was by pulse width modulation (pwm) and position location sensors to control dc motors. I figure I will need to get larger motors but I would like to use the same concept. To that end I was given two old microcontrollers that use the AT91SAM7S256 chip and I am told it come from sparkfun.com. It seams like a good controller to use on this project but I am unsure how to get started, I don’t have a very strong programming background. From what I have read so far I think I would like to just use the free downloadable cam program and then have the micro be the G-code interpreter and motor control with maybe even a digital screen. I have been trying to research how the G-code interpreter works but have not found much help. Also dose anyone know what software to use to program the micro with? On sparkfun.com they do give a free open source program tutorial but I have not had any luck even getting simple programs to run. I am looking for something simpler if it exists. Any assistance would be greatly appreciated.
Do to where I live (small two bedroom apt because of wife’s job) I can not start building anything yet but I figure I can start programming and playing with the circuits! I live in Lawrence KS if anyone else is in the area and would like to start a group.
Thanks
