In this case the code is centrally kept and accessed via the network.
There is a master copy and working copies. They would NEVER write as a
subroutine as the next operator wouldn't understand it. He would however
understand any change made in Gcode. Any changes are supposed to be
documented on the

As you have seen, an underlying problem is that the Gains are IO pins.
They used to be parameters, but it was decided that pins would be more

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 directio

Yes,
I have read that too. I fail to understand what is the meaning of an IO
pi
Just remembered, that the first time I tried that on the Maximat, it worked
too well, and the chuck came spinning off !!
If it's a threaded spindle nose, you have to be very careful of this. At
least close the chuck during testing.
