 If the new number of pulses per unit is brought up too high without changing the maximum motor speed, the motors will start making jerking movements when moved. This is due to keeping the **Max Speed** the same. In order to eliminate the jerking movements, bring down the **Max Speed** value in CNC Settings > Axes/Motors until the movement is smooth again. If the new number of pulses per unit is brought up too high without changing the maximum motor speed, the motors will start making jerking movements when moved.

 +Max Speed is set in units/second (mm/s or inch/s), depending on what units you have chosen in your G-codes settings.

 +7. Set the Backlash in units (mm/inch) for each axis. Backlash is the value that allows for some unexpected play in the machine due to clearance or looseness of mechanical parts. When the controller sends a movement command to the motor, the motor may turn briefly before any actual axis movement begins. That turn is defined as backlash, and can be accounted for in this setting.
