Accurate Strong Gantry

[vargai]

Next one wil have a dual stepper, a leadshine easy servo, which is a stepper with encoder.

Hi Sven,
I read a short 20 page long description of leadshine easy servo and did not find mentions of dual purpose.
Can you point to it ie. link or so?
Thanks
István

Is this the one you are thinking about as shown by Dean :- https://www.youtube.com/watch?v=ZMZdCcLQc4M

Thanks Clive,
I have finished watching it with sound off, complete it later.
As far as I know two standard steppers can simultaneously operate two ball screws
Hope listening to the narrator will make clear everything with easy servos

I was looking into the Hybrid servo from leadshine. There were some things that did not convince me:
-the price of drives and motors and all below combined cause at that price i jumped at top 400W second hand AC servos with drives.
-No AC, so still need a transformer, so rectifier circuit, ~45eur,transformer 80-90euro, time, shipping etc.
-basically the characteristics which are no better than normal stepper
-low encoder count

They could have gained me with absolute encoder for example.


I am not saying they are bad, just that according to me, and in my particular case, the servos seemed better option or stay with steppers. Still time will show, when the machine is ready.

Thanks, yes I am not planning machine to motor, in fact I am planning the suit motor to the machine , but first I have to reorder the frame because
learned my expectation is to idealistic with this gantry desing generally.So I get back to the ground
