Re: Hobbyist Mill Conversion - Reasonable Accuracy

I am not sure what you mean by negative or positive stock? Are you saying I should adjust the dimensions of the model? No it's where you set up your CAM. You make the model in full size. When you are generating tool paths it is a setting in the cam that I use. You tell the tool path to leave or rem...

Re: Hobbyist Mill Conversion - Reasonable Accuracy

I should have clarified my response was to the original poster. He quoted dimensions like .75339 and .75375. That is way beyond what can be expected for accuracy on a hobby mill.

Re: Hobbyist Mill Conversion - Reasonable Accuracy

I think you may be expecting a lot from a hobby mill. Are you actually measuring to 5 decimal places? Being off by a few thousandths of an inch can be easily explained by deflection on a hobby mill with a small end mill with lots of stick out. I generally consider something within .005" to be o...

Re: feeling dense trying to turn the pawn

You have a setting wrong. I can't remember what it is called exactly because I set it long ago. You want to be in diameter mode not absolute or something like that.

Re: Two Machines, Two Wireless MPG's

Setup is very easy. All you have to do is plug the usb receiver into your computer. Then turn on the MPG in the acorn wizard and you are ready to go.

Re: Two Machines, Two Wireless MPG's

I have read about people having two MPG equipped machines in the same shop. It should not be a problem. In this day and age the MPG's should set themselves up.
