I guess you are running these motors on the bench.? If so then they can run rough sometimes when off the machine, it's resonance try clamping them down.! . . . BUT Still there are things you need to set in mach to get them to run something like smooth and not stall(miss steps).

Set the steps Per to match the setup you will run the machine at SO say for instance your going to run 5mm pitch ballscrew then Divide the micro stepping you set the drives to by the pitch. IE 800MS/5mm= 160 in Steps per. This will give you the correct amount of movement and dial the motors in something like correct. Then set the Velocity and Acceleration to sensible figure of 1000 & 300 respectively.

This should give you some thing like smooth movement from motors. Don't set the drive micro stepping to 200 which is the amount of steps of the motors, this will be classed as full stepping which can make motors run rough. Set it higher and you will get smoother running motors. 800 & 1600 are good figures but be aware the higher you go the more pulses required and slower the machine unless you up the Kernal speed in Mach3. Don't set Kernal higher than 45Khz otherwise mach3 can become unstable and could crash machine.

With only 24V you won't get much more than 2000mm/min velocity and 600S/S acceleration.
