I am finally going to attempt my first milling job to cut some circles and need some help. With parameters. My machine is one of those cheap Chinese engravers, so it can't be worked too hard.
First attempt is just to mill a few large circles in some soft plywood. The sheet I have is 5.5 mm thick.
Here are the parameters I need to set in the dxftogcode software that I have.
What is the Z Retraction and Safety margin setting and how should I set it?
What would be a safe infeed depth for my cheap machine for plywood? For lexan?
What would be a safe feed xy rate for plywood? For lexan?
What spindle speed should I use? Slow or fast? (I don't have my tachometer working yet so I have to deal with slow or fast ). I can take the spindle from 0-8000 rpm.
