Beaver Knee mill conversion- by a newbie

Well yes and no really. Yes your 2500ppr becomes 10,000ppr because it's quadrature encoder so 2500 x 4. But in motor tuning you need to divide 10,000 by the pitch of your ballscrew because your entering steps per MM or Inch into tuning.
So 10'000 pulses per rev which becomes your steps per revolution in mach3 is divided by say 5mm pitch becomes 2000 pulses per MM.

Just a minor correction, 2500ppr becomes 10'000Cpr.
Although they're often mixed up anyway, pulse per rev generally refers to the number of pulses each channel produces per rev, which is usually the same as the number of lines, whereas the counts per rev refers to the total number of changes detectable by an encoder counter/reader, which in the case of quadrature encoder is four times the pulses/lines.
