General Mach Discussion / microsteps should not be included in resolution calculations

« on: April 04, 2008, 04:59:39 PM »

Hi

Stirling said in recent thread...'microsteps should not be included in resolution calculations  because they can't be relied upon to be equal in size'

Am I understanding this right & could someone (Stirling ?) expand for me

Mach set to 400 steps per mm
Jog increment 0.01 mm
Jog mode step
So each '0.01 jog' would be 4 micro steps

Does Stirling's statement mean that on one jog the table might move 0.01, on the next 0.015 and the next 0.05 ?

Or have I totally misunderstood ?

If so...
  Is there a regular pattern to this, or is it random ?
  Would it average out over several jogs ?

Many Thanks

John
