Why CNC Machine Lose Step

CNC machine lose step seriously in X-axis or Y-axis while processing.

It shows that cnc router rattled; at that time, no matter by computer output or manually, it can cause lose step.

We can solve lose step from the following aspects:

1. First, lose step maybe caused by too fast processing speed;

See if the setting processing speed had exceeded machine limited speed;

If yes, change into reasonable or suitable carving speed;

2. Second, control system attacked by virus may lead to lose step:

(1) For computer control system:

Re-install the operation system in the computer;

(2) For DSP Handle control system:

Format DSP handle;

3. Lose step leads from driver breakage or driver IC breakage.

(1) Stepper motor is driven by dedicated chip; if this chip is broken or with bad heat dissipation, step motor will miss step.

(2) To driver chip, it will automatically power off once the temperature exceeding 105 degree; and restore electricity as the temperature decreases;

(3) We can solve lose step by:

① Repair or replace new driver chip;

② Add a new cooling fan;

4. Lose step results from broken or wearing router bits:

Replace new and suitable miniature end mill accordingly;

5. When cnc router is interfered outside, it may result in lose step;

Check if there are interfering sources nearby, such as highline, transformer equipment, etc.

6. Coupling on one axis is loose:

Tighten coupling timely;

7. Power instability also could cause lose step:

Replace power supply;

Or add new voltage regulator;

8. Pirated WeiHong Card is a possible reason causing lose step;

Solution: replace new and real WeiHong Card;
