| Incorrect stepper motor settings in Mach3. | If the motor tuning settings are changed accidently in Mach3, it can affect the 'gear ratio' for a given axis. If this happens, you will need to re-load the specific Mach3 configuration file for the CrossFireTM machine. Please consult the Assembly Manual for instructions on how to configure Mach 3 for your machine. |
| One lead screw coupler is loose. | Inspect that two couplers used on each end of the lead screw to ensure that a tight fit is achieved. Re-tighten as necessary. |
| Lead nut is worn or damaged. | Inspect the lead nut to ensure that the threads are not damaged and that the spring tensioning mechanism is functioning properly. Replace lead nuts as necessary. |
| Loose fastener between the lead screw coupler and roller bearing. | Inspect the fastener at the end of the lead screw coupler where it clamps to the bearing. Tighten as necessary. |
| Lead nut fasteners are loose. | Inspect the fasteners that attach the lead nuts to the lead nut mounts. Tighten as necessary. |
