I would suggest reading the stepper motor white paper on the Gecko site.
It is in the support area. It will address a lot of your below
questions. Also take a look at the group FAQ at:
http://www.ktmarketing.com/faq.html
At the bottom is a link labeled:
"Great collection of resource and reference links. AKA: Bill's (the list
mom) collection of links "
Go to that list and start browsing the sites that seem to be relevant.
We will be happy to help you, but part of the help will often be to
point you to the proper resources.
Regarding your specific questions:
Not sure what you mean by hooking the drives together? You can hook them
all to the same power supply or you can use 3 power supplies. They also
obviously connect together on the logic side to the computer.
2 phase is a standard stepper motor. There are also 5 phase motors and
they take special drives. 2 phase basically means that there is 2 sets
of coils.
Regarding a power supply, no a PC supply is not appropriate for a G201.
They specify a minimum voltage that from memory is 24 V. As far as the
+5v for the G201, while you can use an external power supply that is not
the factory recommendation. They suggest you get the +5 from the
computer. If you do use an external supply you have to connect the
ground from it to the PC to complete the logic circuit.
Enjoy reading up on this and let us know when you are stuck or things
just don't make sense.
