Just did a program that had alot of holes in the beginning and in the beginning if the cutout profile I had to stop the machine and rehome. I got coordinates of two opposing holes on furthest corners. One closest to zero was spot on and the one furthest was .09 off. I figure between steps being slightly off, and backlash it's to be expected.
Re ran the program to see if it would be off, and it barely touched the sides of the holes.
Anyone have a good method for doing test and tweaking.
