motor mind B

I am trying to implement the motor mind b on a traveling gantry. I
want to use a rotating disk with a hall effect sensor to determine
the position of the gantry. I have loaded the demonistration code
from solutions cubed manual but when I put a meter on the motor
output I don't get any current. Also how fast can the BS2 receive
input in the count mode of the motor mind?
Thank-you

my motor in reverse direction, using the motor mind b. In the subroutine
labeled "back" (listed below) I have to get the motor going forward at the
duty cycle I want and then send the reverse command. In this program, the
forward and halt subs work well but the back subcommand flips constantly
between forward and reverse. I feel quite certain that I will be embarrassed
when someone tells me how simple my problem is, nevertheless I will
appreciate any help this group can give me.
(P.S.) as per Dwayne Reid's advice I have turned off the html formatting of
my emails. Sorry for the inconvenience. Please let me know if my emails
continue to generate needless gibberish in the header.

I was wondering if u can hook up the motor mind B up to the basic stamp?? And
how u do it..

I am a student of Mechanical Engineering at University of South
Florida.I have a limited background of electronics and through a
friend of mine working on BAsic Stamps, I learnt about this group.
I am working in the field of Robotics and am making a robot arm
gripper. I need to control three DC gearmotors and ensure the work in
a synchronised fashion using a Motor Mind B. I had a few questions as
to how to do it.
1. Is it possible to control three DC Motors using a single Motor
Mind?
2.The operating voltage for each motor is 0.29 A and a peak voltage
is about 0.65 A. Is this voltage too high for the Motor Mind B?
3. How do I connect the leads of three motors to the Motor Mind B and
how do I connect it to the Basic Stamp?
I tried running one motor using a sample program as provided in the
S3 manual. It worked fine. Now I am trying to run a single motor in a
reversible manner using a centre-off toggle switch. What values do I
specify in the program? I mean do I specify a -1,0,1 values for
Reverse-Stop-Forward or do I need a 1,0,2 Values for the same?
I understand that this being my first email and am asking too many
questions. And its quite likely I may be too vague and unspecific
about my queries If someone can provide me some help, I can finish my
projects really quickly.
Regards,
Koushik
