Radius or diameter for a panel connector? Thank You Nathan

Radius or diameter for a panel connector? Thank You Nathan

I think you need to give us a few more details.

Tweakie.

I need to make a hole that will fit a 18 mm diameter round panel connector. I tried to mill it and it was twice it was supposed to be. I set it up for 18mm but it was more like double the size.

Thank you Nathan

The Gcode created by the Cut Circle wizard works just fine. Have you checked that your Steps Per Unit are set correctly ?

Tweakie.

No. How do I do that?

If twice the size, are you sure your units were correct - inch / mm ?

Or were you entering the diameter when it needed the radius?

Yes I am using mm and I did use Diameter. So Radius is what I needed to use? Can you give me an example of when I should be using the diameter?


Thank You Nathan

No. How do I do that?

Section 5 of the Mach3 manual explains it better than I can;  http://www.machsupport.com/help-learning/product-manuals/

Follow Twekies advice, he knows far more than i ever will

You have said you were cutting a hole and it came out twice as big - you have not said how you coded the path - manually, CAM, wizard???

No help can be given in such vague circumstances.

Can you give me an example of when I should be using the diameter?

The Cut Circle Wizard specifically asks for the circle and tool diameter, but as Dave replied, we don't know what or how you are generating the gcode for your work. Your machine must be configured correctly and one of the  steps is Motor Tuning and Setup.

CNC is not plug and play and one MUST learn some things before using their machine. So I highly recommend you have a read of  the  Mach manual and also watch the videos.
