I like the duet 3 for it's drivers and future options/support. Maybe I'll look into trying to remotely drive it using a Zesty Nimble type of setup to turn the screw. That way I won't need a special stepper to sure in the heated chamber. We will have to see. When the expansion is available I'll revisit this again. I'm still waiting to get the uPrint and will see what I can figure out when I can look at it closer.
