Re: DIY CNC not cutting correct size
I would start with some basics. Draw up a square a certain size and see if your machine will cut it the proper size. Same with a circle, both large enough to do some accurate measurements. Adjust your steps if needed to make the creations the proper size. Do this before you waste anymore good wood on a project. If you get your steps right and you still can't make a decent square consistently then its your machine.
