It does the job. but rapid and cut speeds both seem very inconsistant. A combined X/Y/Z and A rapid move will run at a speed such that all axes arrive at the end-point at the same time. What you might be seeing is the linear axes being slowed down because the rotary axis can't keep up. So, an X-rapid with an A-move will happen at very different speeds depending on how far the A-axis is moving. > I notice that there is a configuration page for such a machine on the wiki site, but it looks pretty complicated. What benefits does it have over simply configuring with the stepper wizard, Hard to say without the link :-) Here is the link to the wiki page http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Rot4thaxiskins I have seen. On a number of jobs I have done recently all axix will go significantly faster and at certain points during the job they seemin gly double their feed speed then slow down again. A rapid x move is very slow. I do have very slow old computer.....will this affect speed? None of this makes any sense to me.
