Full steps clatter like a typewriter! They start sounding smoother at
maybe 8-16 microsteps per step. On most CNC machines with steppers, we
aim for 32 step micro-stepping, but this has an added consequence of
requiring vastly higher frequency step signals.
Have fun!

They start sounding smoother at maybe 8-16 microsteps per step. On
most CNC machines with steppers, we aim for 32 step
micro-stepping, but this has an added consequence of requiring
vastly higher frequency step signals.<br>

HI Rob,<br>

What sort of drivers are you using? Are you micro-stepping?<br>
