SOURCE Plate Alignment

The plate alignment function asks you for two points along one edge of your work piece. The greater the distance between those to points on that edge, the more accurate the angle measurement will be. When the alignment function has those two points, it will then rotate the G-Code by that angle for this job. While that rotation is active, the Plate Alignment button will remain green. Clicking it again will allow you to turn off the current rotation, or revert to the previous rotation. 

Machine needs to have been homed, or it needs to be running with absolute encoders that retain the home location when the machine is powered down.

Set your part or fixture zero

Verify the tool path on the G-Code screen to ensure it will cut the entire part from that work piece - not wander off the edge.
