Help!...I have my cnc running great, and in artcam all the feedrates are good...however..I have one of those dinosaur puzzles to do but when I enter the tool and layer heights..I save as..post g-code and in mach 3 it doesnt list the spindle speed (I put this in manually) and the feedrate is set at 60mm/min which burns the wood..also the last set height (I need to be -6.5mm to cut through) sets at 1.2mm...I have managed to set the height somehow..don't know how I did it...and saved that one but I don't know how to get the feedrate correct....please help....Ash
