ZWO EAF to SW dual speed focuser with belt

[barbulo]

Anyone knows a way to attach the ZWO EAF to the Skywatcher 200PDS focuser using a belt? Something like the DIY one in the picture. 
My idea is to use it manually when needed just removing the belt.
I could use a 3D printer for the bracket and the pulleys. 
Would it work?

I think  Pavle at deepskydad can supply a bracket to allow this drop him an email I think Pavle’s standard bracket for the 200pds will fit this .

No need to slip the belt off for manual focusing.

Make the belt just tight enough to drive the focuser reliably via the motor and the knob should still rotate easily for manual use.
I have converted three focusers to belt drive and all allowed the belt to slip smoothly when manually focused.
The belt is not the same pitch as the knurling on the focuser knob. So relies on friction instead of driving the teeth.
Some DC motors can be controlled by specific software but don't have absolute positioning like stepper motors.
Stepper motors must be driven exclusively. You cannot override them manually without losing the drawtube position.

Does the zwo not do a manual hand controller ?

Yes, they do (35€ - not that much). Second option though.
