Hello good people.
Please educate me on servos. I know what they are, i know how they work. In theory.
I had pleasure playing with some open steppers, fairly straightforward.
When i look up servos on ebay or aliexpress i mostly get hybrid stepper servo, which in my mind is just a stepper with an encoder bolted on.
I also have a HUUUUGE 3ph ac servo (3.8kW) kicking about. It doesnt cog, has your usual UVW etc.
Are there true nema17-23 servos out there ? What to look for ?
Having a bit of trouble with my laser cutter at the moment, returning it to get a better one. With steppers, still, but entertaining the idea of servo-rising it in the future and need to understand whole "stepper servo" vs "true servo".
Is there a point to "stepper servos" when speed is concerned ?
Am i making any sense ?
