Tension/Compression Tapping and SprutCAM

Something that’s been on our to-do list for a while is to modify the SprutCAM post to generate code for Tension/Compression Tapping on the PCNC.

Since the release of the Series II (and spindle drive upgrade for Series I), all PCNCs can do tension/compression tapping because of the quick acceleration and deceleration that’s capable with a digital vector drive. If you have a Series II or a Spindle Drive Upgrade and use SprutCAM, then this post is for you (you’ll need a tapping head like PN 31163)

We’re releasing the new post as “beta” and are looking for feedback before wider release. Send me an email if you’d like to give it a try.

Here are some pics with notes on how to use it:

For your viewing pleasure, here is some roll-form tapping with code generated by the post:

Special thnks to Dave P. at Sprut UK for his help with the post as well. And don’t forget our ever-expanding free SprutCAM tutorials library for other SprutCAM tips

PS: Some were having a problem viewing the foundry movie from the last post. That’s now been fixed. You can watch the movie here
