+ | **Rotary Axis** | ||
+ | *The Big laser has a rotary attachment for engraving and cutting cylindrical objects | ||
+ | *To use it: | ||
+ | *lower the bed of the laser down until you can see 2 switches and a socket on the right wall of the cutting area | ||
+ | *bring the laser head to roughly the centre of the bed | ||
+ | *plug in the rotary axis and flick both switches, this changes the laser from controlling the up/down motor to controlling the rotary axis motor | ||
+ | *cutting and engraving is done exactly the same as before, you may need to adjust the vertical scaling to get a nice result | ||
+ | *when you're done, don't forget to return the laser to the state you found it in | ||
