CNC12 Threading (Resolved)

[manojd]

Hi, is it possible to do threading in CNC12 free software using G code in intercon?

Thanks.

Threading will require a spindle encoder 1:1 with the spindle and Centroid Lathe Pro available here:https://www.centroidcnc.com/centroid_di ... oller.html

It's difficult to tell from the website info, but I believe based on experience that is, no.
You have to have encoder feedback and that is available in Pro only.

NO threading or rigid tapping with out the PRO version of the software. And yes you also have to have a differential encoder belted to the spindle with a timing belt at 1:1

Thanks for all the replies. I do have an encoder which works in the free version as well. But, looks like I will have to upgrade to Pro for threading. I tried adding G76 codes into intercon program, but it stops when it hits the threading code.

Does the software not tell you to upgrade to Pro when it hits those cycles?

Yes, it did.

Yes, it did.

The features work provided you have a good differential line driver encoder belted at 1:1 to the spindle with a timing belt.
Good luck!

Got everything working. Threading works wonderfully after setting parameter 240 to -1. I can do internal and external threading. I do have one concern, the internal threading bar(s) seem to approach/retract much more than expected. I need to do really tight internal threading. I did set the approach and retract parameter in intercon, but it does not seem to take effect.

Awesome!
Post the code, and a report
