Didn't change any of my settings. Copied myscreen.set, machlic.dat, mach3_4axis.xml, my macro folder, my image folder, my machmill shortcut that loads my profile. Uninstalled mach3 0.020, deleted c:\mach3r, installed mach 0.033, rebooted, copied my files back, started mach.
I've done this 2x now and both times mach overfeeds velocity by about 25% on all jog and feed moves.
Attached is my .xml
