Hey,

I am looking for a fast stepper motor with high step angle as they are hard to find new, you probably find them in printers

I am playing around with laser pens trying to make accurate scan lines

I can swap for a standard quite strong nema17 one (that works fine) I pulled out of a photocopier

Thanks
Ben

its mainly so I don't need to send really fast signals to it

so anything between 9 and 90 I would like to experiment with

all the commercial sources seem to only sell the 200 steps type or funny geared ones.

Their parametric search is virtually useless for some products, the underlying
database is of very poor quality.
