The cheesy, low cost way to test steppers is to get yoru step signal,
on line to the driver, the other to a board. then from the board to
the driver.
put a hole in the board for your axis.
put on 2 circles, one at 2" the other at 3"
put thumbtacks, nails, screws or whatever at 12:00, 3:00,6:00 and
9:00 oclock postions on both circles. at each hour is better as
close as possible is best.
connect all the outter circles to the signal/power wire you brought
to the board.
connect all the inner circles together, drop the wire down thru the
bottom and then to the driver.
with a piece of wood and a metal plate of some sort, make a crank so
that as you spin it, it will contact each pair of tacks making a
pulse. spin the unit and you will create pulses that will signal the
driver to pulse the motor.
this is a really poor type of enocoder, but if you don't have a puter
connected, it will work.
You would probably be better off chopping an old printer cable and
using TurboCNC to test things. IMHO as then all you need is to feed
a 5 volt power signal from the game port to complete the signal loop.
