General Mach Discussion / Re: Something HAS to be wrong with my steps per inch....
« on: September 06, 2011, 07:41:57 PM »
Yep. Sure was.
Here's where it gets really interesting.
I reset my steps per inch with mach loaded up with no G code.
I had to set it to about 100,000 steps per inch to be in the ballpark of 1 inch. I knew this wasnt right, but it worked....sort of....The DRO on mach read 1 inch of movement for 1 inch of travel.
Then I loaded my G code, and the steps per inch was no longer accurate. It changed, with my G code loaded, to where I wanted to be, 4000 steps per inch.
Great, I suppose, but why did my "steps per" change when the G code loaded?
