Some developer went to the trouble to add the very nice
FOAM mode to axis, which looks great. There just seems
to be some problem with kinematics that won't drive the
second pair of joints. I've tried changing to joints 6 and 7
instead of 2 and 3 for the U and V axes, but that didn't
work. There
I don't think there are a whole lot of foam cutters out there period. But with
my very limited knowledge of the subject, I would have thought the JA version
would be better suited for it. It is possible that some of the workarounds
that had to be done to make the wire cutter work with the ear
I'm getting the impression that I'm the first one to
actually try post-2.7 linuxcnc on 4-axis foam
cutter hardware. I've set up 2.9-pre0 from git so
I can start poking in the source code. 2.9-pre0
behaves the same way. I have verified that axis.x.pos-cmd
and joint.0.pos-cmd both change as expect
Jeff,
Cool, thanks for doing this work.

You can make a broach, if you have a lathe.
Start with a piece of square too

Re-reading that, linuxcnc will not even start if they don't match
exactly.
That's not my experience. What error message do you get?

The feed and spindle speed looks about right. I'd use carbide then
double or triple feed + speed. With carbide in steel, coolant/oil is
optional. A lot depends on the rigidity of the machine and setup but I'd
also probably take the cut in one pass or maybe two. Making lots of
small passes is ha
John. You really really should be running carbide endmills. They can be
run dry and hot for most jobs. And they are just so much nicer than hss.
It's great when you don't have to think to much about if the cutter is
going to overheat. And more just about what shape you want to cut.
