I am making my own junkplotter. I'm using an older Demi-arduino with a Adafruit motorshield to drive some steppers from a printer. I'm using a reduced the 3rd Gen Firmware for the Sanguino on my arduino to receive instructions from replicator-g. Right now, my plotter is responds to the control panel and it is drawing, but it pauses when I try t

So there is a timer that is just ticking like a clock and each tick interrupts the normal operations (the collection of packets, the processing of those packets, and the checking of the optos) to do the actual stepping. And the timer is set up when initializing the stepper code. The program pops back and forth between the higher level operational code and the stepping code by way of the

Hello,
While I've got a pet project that will eventually result in a custom firmware, I'm trying to understand somethings that are going on in the current 3g firmware, before I'm slicing it up.
Quick background on my pet project: This is a learning project to build a simple pen plotter that
a) implements the communications protocol rather than interpret directly on an microcontroller (in my
