Someone is offering me a Bridgeport Series II Interact CNC mill. He
says that it worked but the Heidenhein controller is no longer
operational. Whether this is true or not, as always is questionable.

The price is $500.


Heck if if the CNC is totally dead you can completely retrofit it to run
with Mach 3 for 500 with new motors even and add a cheap PC.

$500 for a big mill sounds pretty cheap whether any of the CNC is good
or not.
Probably not quite. it is almost certainly a servo-driven machine, not
stepper. $500 with new motors? Do you know how big a Series-II is? It
stands about 8 feet tall and weighs 5000 Lbs. It uses NEMA size 42
motors driving the leadscrews 1:1.

How hard is it to take the head off to make it stand lower? 8 ft will
not fit through my garage door, fsck

If it's the same machine as the one the other guy converted that you
provided a link to, it looks pretty east to remove the entire head/ram
assembly from the base, if a bit high and heavy.

Obviously there will be various cables to disconnect if you need to
fully remove it, but perhaps you can manage to suspend it from an engine
hoist off to the side while pushing the base under the doorway and then
reinstall it.
