I might be doing some high density foam.... mold or pattern stuff Mark and
the high speed might come in handy as foam is much easier to cut then
aluminum.
According to the guy that replaced the servo amps the spindle runs at
up to 7000 RPM. PL
I guess another questions is. Will any of this software/hardware support a
Fadal
add on tool changer?

1.5Hp driving an axis at 300ipm doesn't really care what you put in it's
way. Foam, Al, Steel, Fixtures, Vices, Rotary Table. At that speed,
something will give! 5IPS is fine in production once you know the program is
really bug free, and you know how many runs before your tooling gets blunt
etc. But for for one off or short production work, that is way too scary.
Running slower means yu can at least believe you have a chance to intervene
and prevent a crash.
Tool changers are normally not controlled directly by the controller. No
Tool changer will be plug and play. There are only place holders in the EMC
and TurboCNC code for this as each application is different. Ray Henry, one
of the EMC guru's has a good write up on whats required here:
When we do foam there usually is nothing in the way of the x or y axis.
Except the limit switches.
We do need something fast as a lot of material is removed.
Especially on something large like a 3D contoured bell housing pattern.
Many many tool paths are involved to get the smooth surface finish necessary.
I am not sure yet what constitutes the tool changer interface but I suspect several
digital outputs would be required. Perhaps some handshaking.

Basically it is easiest to ofload the tool change logic onto a PIC, and just
trigger it, pass it the desired tool number and wait for the confirmation
signal to continue.
