I’m looking at the possibility of moving to Mach 3 and the G540. But I’m finding it difficult to find truly useful information (other than someone who’s so opinionated that we have no right to use the combo with an X-Carve :D). What I’m thinking is that, at it’s minimalist core, all I need to do this is a computer with a parallel port (have several lying around with versions of XP, Vista, and 7 installed and running), a power supply (48v), a G540, a few resistors, and some cabling with DB9 connectors on one end, and a fan or two. Am I correct?
Yes, one can easily move beyond the very minimalist config above, but my question is is that all that’s truly necessary? And then assuming the 140 oz/in nema 23’s (from Inventables), what resistors are needed (that’s where my brain truly stops working)?
Thanks in advance for any answers.
