Servo Motors to replace steppers

13

Thanks for the reality check. I see the replacement stepper motors on the 1F website are about $21 while the Clearpath products start at about $260 – a factor of 10 greater! I was mislead by the comment at the end of the video where they say the Clearpath products are “less money than a comparably powered stepper motor”. In listening more carefully, I notice that they said earlier in the video that “if you don’t need [the amount of power that the Clearpath servos have], a stepper motor is going to be more economical”. Just a thought on my part, and a question for you: with the possible upgrade to the 80mm brackets for the significantly heavier 80mm spindles, do you think that the existing stepper motors will be able to handle the increased mass over time without failing prematurely?
