thanks mike. sorry i miss typed. what i meant to say is: the power supply in the kit comes with more amps to support the fan as well as the motors.so if someone is buying the parts separately make sure your power supply has plenty of amps. the kit has never gave me any trouble.
thiers is no doubt in my mind that gecko drives are better. 90% of the time you get what you pay for. but for the money (i got a 4 axis 354oz system,power supply,and motors for less than 300 bucks)
also the mach 3 that comes with the kit isnt a good one/to old or something. down load a copy of mach from the web site.
i went for cheaper and now i have a machine i can build a better machine with.
