Hello Everyone

I am a 360 degree shoe photographer. We rotate products and photo them many times to create
spins for the web. we currently turn the disc by hand.
We have built a nice machine - but have had lots of trouble driving the stepper motor.
If anyone has had experience with driving motors - and can pop down to our studio in london
please click on this link to read our brief with photos.
i look forward to hearing from you - thanks james

How many steps per rev is the motor?  I did exactly this on a 1 metre diameter clock face a few years ago, and without microstepping the motor or using a large gear ratio, it was impossible to get a smooth ramp accel/decel motion. The other thing I did was to use one index position and then do all the rest by counting step pulses.

North of the river at this time of night?
Are you mad?

I have been North to Whitechapel  & I still bear the scars.
3 hours to do 30 miles, £28.00 to park and £10.00 congestion charge.

are you stilling looking for help with this?

I have already built 'duino interfaces for the various parts you need:
a) stepper motor
b) camera trigger

if you're driving the stepper correctly you don't need a sensor
so then the flash won't interfere!

what photo kit do you use?
I'm a Canon man, but I will talk to Nikonites!

cheers
Mike
