I triple checked the pulse per inch amount and it's perfect.
For a toolchange the machine rises to Z Rapid and remains in the same XY location.
After looking over the mechanicals of the machine I found something interesting. Even though I am getting .0005 accuracy with a dry run, when cutting the gantry is skewing about .02. I knew about this problem and had ordered the materials for a proper bridge but for some reason it had slipped my mind while troubleshooting. After getting my double deck 2 inch aluminum slab/gantry setup I'll post again with new results.
