I am working on designing a bolt together steel tube CNC router and I am trying to source my stepper motors so that I can incorporate a specific motor into my design. I saw that keling is having a sale on Nema34 3.5 Amp 465 oz in holding torque dual shaft stepper motors (Page Title) and I was thinking about buying them to pair up with a gecko G540 drive. The problem is that my design will only need single shaft motors. Is there any downside to have an extra shaft sticking out on the other side of the motor?
