Acceleration around corners

Okay, we cut a sign last night and noticed something strange. It seems that the machine is compensating for velocity and cutting the corners off. Is there a way to make it slow down to the corner, make the turn and then speed back up?

I know Mach3 has a CV setting or something like that so does EMC have the same type thing somewhere?

Thanks!

So the G64 at the beginning of the gcode is my problem? I should change this to a g61 in order for the path to be followed correctly?

G61 will stop at corners, that might cause problems with rubbing/burning (though this is unlikely). G64 P0.01 or similar should give you the best of both worlds. Change the numeric parameter to suit.
