Quick? question for Dan.

I am using a Camtronics 2A board with Sanyo Denki 2A motors
*********
Stock #, Torque, Amps, Volts, Ohms
232-180-SB, 180, 2, 2.1, 1.05
*********
Each axis is protected with a 2A slow-blow fuse.
Before I begin, let me say the motors are new, I had been running 2
axis fine with old salvage motors rated at 1A.
The reference voltage for "hold" is set at 0.25v, and "step" is (as
best I can measure) not over 1v (0.97v).
I got X axis working fine, but when I got to Y, the motor went slack.
Got a sickening feeling that I blew the output stage before I noticed
that it was just the fuse that blew.
MY QUESTION IS:
Did I buy the wrong motors for this board, are the fuses too
sensitive, should I lower the "step" reference voltage, or should I
be looking at the 5A board? Does half-step have anything to do with
this problem (I'm half-stepping).
