I have my motor set to 50 IPM max and when I load a g-code it only runs at 6.00ipm, how do I change this? as you can tell by my question I am new to this any help would be greatly appreciated, my email is csmoak25@yahoo.com and thanks again

Your G Code should have a feedrate in it, for example if your code has G1X10Y2 it will run at whatever the feedrate is set at that time, Mach defaults to 6 at startup. However in G Code you control things so your line would be G1X10Y2F40 and that would move at a rate of 40 IPM in your case.
