Ron I rechecked my machine, Using the latest version of Mach it still does it. I think it is tied internally somewhere.
If on the pulley settings page, the ratio is set to 1 then the Wizard displays the correct spindle rpm in the dro. If you set the ratio to 9 (bridgeport Lowrange) then the Dro still displays a version of the spindle speed that has had a divisor applied.
Hold on?

? Now that I think about it. "Before" Art added the ratio in the pulley setting. I had to devise a way to get the corrected spindle speed to display. I may have modified the screen DRO to apply the divisor. LET me check something!!!

DANG RON, It was me all along. I had to replace the screen dro with a DRO that had a divisor running in the background. Can you guess which DRO I used. YEP 1101. SORRY (;-( TP
