I'm trying to see if my Discovery 308 with DX32 Control will thread mill. I found G12/13 in the manual but the first line has me confused a mite. It says to do a polar move to the start G0/1 A_ I_ J_R_ I understand what A is Angle, I and J are offsets from the center of the circle and R is the radius of the circle. Is the manual trying to tell me to move to the start point then set the parameters of the circle?

And if I didn't have the "high performance" spindle I'd convert this to LinuxCNC in a heart beat...

Thanks

The DX32 control does thread milling very well. You can do it in a couple lines. I have a few older threads that may be of help getting you started.

It is also discussed near the end of this thread:

Not sure what CAM software your using but I have a proven post for VisualMill and Fusion 360 if your interested.

Thanks for the links, I use OneCNC and have Fusion 360 so I could use the post processor for Fusion.
I assume this link http://home.lewiscounty.com/~forhire/posts/ is the Fusion 360 posts?

Correct, this is my Fusion 360 repository. I just reverted the post to use G12/G13... I had switched it to G2/3 so I could back plot the path. Nate mentioned he was seeing a drop when using G2/3... I wasn't but G12/13 is the correct method. If you encounter any issues please let me know.
