I'm considering building a Workbee, but I'd likely buy a 1000mmx1000mm mechanical kit, as I've got plenty of spare electronics parts from previous projects and I like things to be highly modular. I was going to re-use my CNC shield and Arduino, along with DRV8825 drivers - but I don't know if this will be good enough for the 4 x 175oz stepper motors. I already have a 350W 24V PSU, which I was planning to use with these (if it's powerful enough). I notice that a lot of people here directly interface some DQ542MA (or leadshine DM542T) steppers with an Arduino - could I run 4 of these and the 4 x 175oz steppers from a single 350W 24V PSU? If that's do-able, I'm tempted to go down this route as it's very modular and I can re-purpose them in future. Also, as the machine uses 4 stepper motors - do I need 4 separate drivers or can I connect the two steppers on the same axis in series to share a driver and make do with 3 drivers? Many thanks for any advice!
