If the step/mm value before, which caused it to move 100cm when commanded 100mm was accurate, then you just need to multiply it by 10.

There's a bit more to it though. You need to make sure that you don't hit the kernel frequency limit in Mach3. It's best if you can to use the lowest frequency, which is 25kHz. This means the port will output a maximum of 25000 pulses per second, so if you divide that by the step/mm value you get the software limited maximum feedrate. For example if it's set to 2000 step/mm, then that's 25000/2000=12.5mm/s or 750mm/min. If that feed-rate is too low, then you either need to reduce the microstepping resolution (e.g quater stepping instead of 1/8th) or raise the kernel frequency.
Ok i went to the workshop and in motor tuning ive set steps per to 20- Velocity to 3000 accl to 200, Oh im using metric, now when you type in X1000 the gantry travels 1M so that much is correct but im not sure it is the only way to do it the drivers are on the lowest setting which is 200 per rev. with four people sitting on the gantry it dosnt evn know you are there..
