Large Toolpath and Mach Pauses every couple hundred lines

[spinningwood]

I have a large rotary toolpath with about 1.2 million lines of gcode.  When I run the file Mach3 pauses for a couple of seconds every couple hundred lines of code.  As a test I deleted a bunch of the code so that I only have the first 10,000 lines in the file.  Lines 1 to 10,000 are exactly the same as the first 10,000 lines of the large file.  This smaller file runs perfectly with no pauses.

I have look ahead set to 200.  Looking at diagnostics I don't see any indication that the machine is overloaded.  It's a pretty fast computer.

I see that the limit for Mach3 is 10,000,000 lines of code.  I'm nowhere near that.  Any suggestions on what I should be looking at to get rid of these pauses?  It's a 12 hour job if it runs smoothly.  The pauses will add a lot more time.  Not to mention the problem of having the bit turn in place every couple of inches while Mach is doing whatever it's doing while it pauses.

Thanks.

Try turning off the toolpath, button is on Diagnostics page above Reset button.

Hi Hood.  Thanks for the suggestion.  I'll give that a try first thing this morning.  I sure hope it works.

Hood, you are a life saver.  Turning off the toolpath display solved the problem. 

Maybe I'll get this job done before the weekend!!  Woohoo!!!

Thanks a bunch.
