Each axis of a two-axis laser cutter utilises a stepper motor with 48 pulses per revolution. For each axis, the output is coupled to a lead screw with a 14:1 gear reduction and has a pitch = 1.8mm. The table is required to travel along a linear trajectory with neither axis exceeding a travel speed of 200 mm/min. To achieve an incremental position of 250mm along the x-axis and 100mm along the y-axis, determine the motor speed (in rpm) required for the y-axis.
