Greetings all.
I've just set up my system with a 4th axis and straight away ran into a problem of stuttering movements and pauses of several seconds of the linear and rotary axes. I was using an HP laptop (2.8 ghz) and had been for some time with excellent results, but it seemed like the rotary axis tipped it over the edge, so I've changed to an Athlon 2500xp desktop computer, with separate video card and 1.5gb ram.
Running the same test file as I ran with the laptop, there was an immediate cure to the stuttering rotary/linear axes. What I hadn't done though was swap over the Mach3 license file to the new system, so I was actually running in demo mode with only part of the file being processed. When I did install the license file to the new system and re-ran the test file, which is about 9mb in size and consists of mainly X and A axis moves, all the stuttering returned, but not as severely as with the laptop. Removing the license file eliminates the problem again.
This one's got me stumped. Why would the license file cause this problem, other than allowing a larger g-code file to be used, but I'm not able to see a connection as 9mb (around 500000 lines) isn't that big anyway is it?
Thanks for any help.
Martin.
