CNC7 Rigid tapping unlocked but not present in Intercon

Post by wpnichol »

Hello,

I have a ~1999 CNC7 Atrump K3FLC that lists rigid tapping as [ON] in the installed options menu, but it doesn't appear anywhere in intercon to select rigid tapping as an option. Not too big a deal, but if someone has any easy answer about the discrepancy, it would be appreciated.

Thanks!

Your machine does not have the mechanical or electronic components needed for rigid tapping.

You can use a self-reversing (e.g. TapMatic) head.

If you have (or add) programmable spindle speed through a suitable PLC and VFD, then you can use floating (tension/compression) tapping.

The only reason the rigid tapping software option shows "On" is because of a grandfather date, prior to which rigid tapping was included with the floating tapping option, and did not have a separate unlock.

Great, thanks so much for the quick reply. I also wanted to thank you for all the great info on your website that helped me
get this machine going again (it had no motherboard at all). I replaced it, added some PC104 spacers, custom adapter cables, and she fired right up!
