Hey guys, well after many days of stuffing around with many test circuits i finally managed to finish my motorised focuser
It incorporates a Japan Servo 0.6deg 3 Phase 1.5A stepper...
I set the unit up with a regulated 555 driver supplying from 6hz to 133hz with a full 50% duty cycle up to 100hz. I could increase it more but i went for accuracy instead.
So far ive set the controller up with switches for:
frequency>forward>backward>halfstep A>halfstep B> full stepping>motor lock
The halfstep is great for precise movements and low vibration with full stepping supplying massive torque at the cost of more vibration and the motor lock is great for locking the position of the motor and whatever is attached to it...
So far ive been very impressed with it and im glad i went with silicone cords as they are amazing at staying untangled
i cant wait to get the order through for my FLT-132 so i can mount it up
Just curious what you guys have come up with for your scopes as this one was certainly a challenge
