Instead of just attempting a re-wire, I'm thinking I'm best putting together a new box entirely with better parts. Would a Gecko G540 be sufficient or overkill. Also, would it be best to replace my current stepper motors (57 two-phase 3A 150N.cm) for something a little better. And if so, what? I'm not interested in crazy fast cutting speeds. Just need to be able to cut wood, acrylic, ACM and aluminium reasonably well with the 6040 frame(until I can get something better built.) I also want to keep using the SMC4-4-16A16B - and maybe add some sort of switch to an external parallel to connect to a PC if need be. What would you recommend?
