General Mach Discussion / Steps Per Inch

« on: February 27, 2007, 07:27:08 AM »

Hello,

My current cnc machine has a direct drive  20 degree tooth pinion and 20 degree rack setup.

My current stepper motors are 640 oz 1.8 degree 200 steps per inch.

So when I calibrate steps per inch in the settings page I wind up with somewhere around 639 steps per inch.

My machine cuts fine but the low resolution shows on circles and any radius I cut.

Is there anyway in Mach3 to increase the resolution (steps, a multiplier) or is the only solution mechanically such as a gear box or geared motor.

Thank you,
Tom

General Mach Discussion / Edge Probing

« on: December 15, 2006, 03:42:56 PM »

Hello,

I have now gotten my probe connected and working.
and would like to do some edge(profile) probing with Mach3.
Is there a macro or wizard available for this function.

Thanks,
Tom
