I'm using freqmod and I have the Period set to 0.000016 I have the
acceleration settings all at 2.0.  I ran a quick test with a dial indicator.
If I zero the indicator and do a GO Y3 to move away from it then a G0 Y0 to
move back the dial indicator is within .001 (I don't expect too much
accuracy from the flimsy mag base). If I do a G1 Y3 and G1 Y0 the Dial
indicator is off by approximately .020.  The results have me puzzled.  Any
ideas?  Will changing the PERIOD value fix this?
