I have a V2xt with a DX-32 control. I have maint. manuals but nothing with list of G-codes supported. I have a thread milling job and was unsure if the dx-32 supported helical interpolation. If so does any one have the syntax used? Thanks Coop

Try adding a Z move to the G02/G03 moves.

Thanks,
It worked fine.Sometimes the answer is sitting right there .

You are missing the programming and operating manual which lists the G and M codes. There is a "canned" G code to do helical. Helical means a certain Z distance move while moving in a G17 X and Y circular move and this Z move to be accomplished in a certain amount of degrees of a circle and you can increase or decrease the radius of the circle.
The Bridgeport also supports a G79 which was a very quick and dirty way to do a circle with an arc in and out.
Check with machinemanuals.net to see if he has a programming manual.

Helical interpolation is G12 for CW and G13 for CCW.
Requires a position move to start point using polar coordinates.

G0(G1)R_ I_J_A_
G12(G13)A_Z_F_

A is the total number of degrees.
Z is the Absolute Depth of travel.

Cutter comp CANNOT be used.
A range is from 1.0 to 65535.0 degrees.
Helical cannot be transformed.

SPIRAL INTERPOLATION use polar data to achieve a start and end radius that is different. Use same start line but:

G12(G13)R_A_Z_F_

Now you have good data.
