in x, y, z. The G-code interpreter is also written to accept and process 6
axis of motion. The bottleneck, IMO is in the motion planning software
and that is a work in process. Several folk, myself included are building
four or more axis milling machines in anticipation of the new motion
planner.
Well I've seen speeds up to 10k on my bench but this is one limit that
you will bump up against. There is a trade off between rapid feedrate and
resolution. I only use microstepping so I don't have serious resonance
problems and that limits me to something like 80-100 IPM.
parallel port boards that will drive steppers at a much higher frequency.
Word on the price/availability of these should be comming along soon.
linuxcnc.org/Dropbox. You can do a manual jog on the fourth axis but no
mdi or auto for that.
My advice is that you should go ahead and build it. When you get the
mechanical and motors ready, post a note to emc@... that reads,
"Where's my five axis version."
As folk a bit to the north of you often say, "tcheus."
