# Hardware: Machine Errors
## Engraving Accelerartaion Issue
Machine error (German): Nicht genug erw. Sper Bitte "Esc"  
Machine error (English):

When engraving elements are placed very close to the edge of the work area, the laser head cannot accelerate/decelerate in the X direction enough. The head needs some space to speed up or slow down. 

**Solution:** Place the engraving pattern farther away from the edge of the work area. Alternatively, move the origin closer to the center of the machine bed.
