Hi,

I have a SuperJack QARL 18+ used on a Laminas 180 (more info on my setup HERE ). It's powered by a MOTEK positioner.
The problem is that the motor is not accurate in stopping at the stored position. I often have to correct the position by a few pulses (from 2 to 10).
I have dismounted the motor but the gears seem fine and the movement also seems smooth.
I would have thought of slowing down the motor by lowering the voltage with resistors....

Does anyone have experience with this or any other suggestions?

Thanks for any suggestion!
 
Rose joint/end bearing bolts if you think the original polarmount bearings are OK?
 
I have the same actuator, it's ok if you can connect it to a different positioner
