Hi all, first post here. I recently bought a Techno 49" x 41" with older stepper motors and MAC200SD controller. I just got off the phone with Techno and it looks like I need to upgraded the controller and it was suggested I replace the stepper motors with servos. I want to run Vcarve Pro. Do I have to buy a setup from Techno for $4k or can I retro fit something off of eBay or else where? Thanks in advance for your advice!
