control printrbot with custom firmware
I am working on a simple project that requires controlling the printrbot simple metal. I am only controlling the head position in x, y, and z. The hot-end won't even be installed.
I know that this will consist mostly of sending g-code over usb but I need details on communication protocols and any peculiarities in the interface. Can anyone point me to a resource for this information? Worst come to worst I can plow through the source code for repetier or cura but being lazy, I was hoping to avoid that.
Thanks in advance.
