need a little guidance with an arduino controlled CNC machine. help? Answered
ok so I am in the process of getting the axes set up, and theyre in a state that would allow me to test them. I am using the laser carriages from CD-ROM drives, so i know i wont get amazing build sizes, but that isnt the matter here.
I've searched and searched and searched and have yet to really find definite instructions.
The hardest part is going to be coding the arduino. I would like to use an ATmega16, but a 328 will work too. I intend on using L293D's to control my motors. they seem to work fine for on the bench testing, so with cooling in an enclosure i dont see why it wouldnt work.
but I have no idea where to start with the coding. Ive seen references to GRBL, some reprap stuff, and a LOT of people being told basically "your method is stupid, buy these motor controllers and use my method", which i guess works well, but I dont have the money to buy the fancy motor controllers and the 293s seem to work fine.
so, can someone point me in the right direction, or give me some pointers here please? I'd really appreciate it.
