Pausing at Nodes

I've been experiencing a problem the last few times that I've been cutting. I'm cutting out some large commerical signs with very simple/large letters. The last few jobs that I've done I've noticed that my machine slows down significantly at each node. Each letter has 4-8 nodes total depending on the letter. Even on arcs that are as smooth as can be (example: the letter "O") it will slow way down at each node. At first, I thought that it may be my cut rules slowing it down, so I tried it again without any cut rules, and it cut exactly the same. I have my following tolerance set at the standard .010" and it hasn't done this before. It just started a few weeks ago.

If you use the standard SheetCam postprocessor then it may be worth a try changing the following in the GCode file:

From:
To:

I'll give it a shot. Is there a way that I can take it out of the post so that I don't have to remove it from every gcode file? If not, that's fine too.

Sure, it is in the current postprocessor at line 72, it looks like:just change it so it looks the same.

Is this the spot that I need to change? Still having a lot of issues with it slowing down at a really small area that the table shouldn't have any issues keeping up the velocity in.

    if scale == metric then
        post.Text (' G64 P0.254 Q0.025 (tracking tolerances: 0.254mm)\n') 
    else
        post.Text (' G64 P0.01 Q0.001 (tracking tolerances: 0.01")\n') 
    end

just change it so it looks the same.

I have revision F if that makes a difference

It seems to have been a sheetcam issue with import tolerances being too small!
