Replacing Servo motors

[m_c]

Cheers Jazz.


I got an email back about the cost of the DMM servos and shipping, and by the time you factor in all the extra bits (cables, software etc) it's about 1900USD, before getting hammered by tax/vat/fees at this end.
Plus the 750W servos are limited to 1080rpm, so there's not that much of an advantage over steppers in terms of where power/speed is needed.

Yep and this is exactly why the closed loop steppers are going to knock the spots off low speed low end servos like this. They work just has good and far easier to set-up, non of this PID tuning etc. It's available if you want to play but they will work just fine straight from the box and infact the drives auto config handles it has default and really it is just an advanced feature if you want to tweak.
