Just remembered, that the first time I tried that on the Maximat, it worked

If it's a threaded spindle nose, you have to be very careful of this. At
least close the chuck during testing.

To use a Tapmatic head you just need to calculate the feed rate based on
rpm and pitch. They are self reversing so you feed down then feed up
without stopping the spindle. Even if you stop the feed the tap will
stop turning at some point then when you reverse the Z the tap will
reverse
That would be in the User Manual.

Syntactically, there is a difference in these pin types simply because
the parsing rules in halcmd say there is a difference. In particular,
