I looked on the Wiki, and believe I could provide something that
would be useful. I could include more information to give a more
complete treatment of the time limiting factors of using stepper
motors. I have a few questions to try to make it more informative, and

Hi Kirk:
Have given your suggestion of tuning up the setup I have and will proceed
toward that end.
I was wondering if u could tell me what this means: Setting PFD, "Adjustable,
percent fast decay". The manual I got with my stepmaster stepper board says
this should be adjusted for each axis.

If you already have a breakout board for your steppers, this could work
for a PWM servo amp. EMC2 has a software generated PWM signal, but it is

Hi all:
Happy turkey day!
Does anyone in this group have experience with CNC4PC servo controllers?
I want to upgrade to encoders and this looks like the best so far.
