General Mach Discussion / FEED SPEED OVER RIDE PROBLEM (FRO%)

« on: February 18, 2008, 11:15:16 PM »

im having problems with my updated version of mach 3. i use to be able to increase the speeds of the router past the programed speeds set in the g code. i use sheet cam to program my sheets. i set me feed rates lower than maximum speeds that the router can handle to make sure the program starts properly. now that i have the latest version of mach 3 i can't go over 100% feed rate on the router. is there something i can do to change this so i can get my feed rates higher. every time i stat up mach 3 it is set at 100%. i like to have it there so i can manually adjust the feed rates as the sheets are being cut. this problem has casued me alot of extra programing because i have to adjust the feed rates for each cut. the ones that are thinner can be cut alot faster and with out the feed rate over ride working properly i cant increase the feed rates and the sheets are taking about 2 hrs longer to cut out.
how can this be changed? do i need to go back to the older version of mach 3?
