Afternoon All, This is my first EMC Users post (first mailing list in a while actually), so please be gentle with any etiquette misdemeanors !
I'm just beginning to put together a design for a hobby CNC machine, with my own driver board electronics - glutton for punishment really. Looking around, EMC seems to be the way to go in terms of controller software - as a GNU/Linux user, because this hobby project is on a budget, and because it looks to be nicely featured and extensible. So, my question for the time being is, are the parallel port signals (ie. the waveform/timing diagrams) documented anywhere ? For instance, are the axis step signals sent as pulses (ie. step the motor once per low-high transition), or are they flat (ie. keep stepping the motor until the signal goes low) ? I've seen the StepConf documentation - which is the closest I've found - but that doesn't really explain a lot (it's more end-user oriented). I'm sure I will have more questions, especially around timing, so if there is a source on the 'net with this sort of low-level detail that I haven't seen yet, I'd appreciate a link. It's either that or you're going to get sick of my constant e-mails pretty quickly...! Thanks in advance.
