Hi Scott,

My helix is appearing as a large circle rather than a small corkscrew that I'd expect. I've looked at G130.PRG and I'm confused. Either I'm using the wrong one or I need to re-write the one I'm using. This is a snippit of the code I'm playing with.

G0X-0.3915Y0.2498

G1Z0.025F1.

G0R0.015I-0.4065J0.25A147.4389Z0.025

G13A504.Z-0.0625F2.

G3X-0.4215I-0.4065J0.25K-0.0625

X-0.3915I-0.4065J0.25K-0.0625

The control is a Bridgeport DX-32 and this is the syntax from the manual.

G0(G1)R__I__J__A__Z__ (F__) ;Move to Helix Start Point

G12(G13)A__Z__F__ ;Do Helix

G1 is the G-Code for XYZ Linear Interpolation (Feed);

G12 is the G-Code for Helical Interpolation in a Clockwise Direction (CW);

G13 is the G-Code for Helical Interpolation in a CounterClockwise Direction (CCW);

A__ is Polar Angular Motion defined in terms of the total number of degrees of

helical travel (for G12 & G13 only). This is an “unsigned” incremental value;

Z__ is the absolute depth of travel;

F__ is the Feedrate;

R__ is the Arc Radius; and

I__, J__ are the X & Y distances (respectively).

Thanks in advance.
