camtronics vs gecko

Hi,

Thanks to all for the previous help given, and I have my systems
running well now. Only some small questions:

With the Camtronics 2A board set for 2A, PS 36VDC, Sherline 2A
stepper wired for half-coil, and lathe (lead-screw 25.4 tpi), I could
get up to 16 ipm.

When I switch to the Gecko 201 drivers set also for 2A, 36VDC, I
could only manage 10ipm.

I thought I can get better speed with the Geckos? What am I doing not
quite right? What are the others getting?

Perhaps it is limitation of the pulse rate? But it cannot be? because
if it is the max pulse rate output, the system should just move at
that speed corresponding to that max pulse rate without faulting out
irrespective of how high I set the feedrate? But this is not so, as
the max ipm I quoted was the steppers faulting.

Will be interested to hear what the others are getting. Thanks
