It's stopping/decelerating for every line segment of curve

Getting my machine up and running, it handles long straight lines without a problem, but when doing a non-circular curve composed of many small G1 line segments (each ~1.5 mm in length), it stops (or nearly stops) for every single point.

Is there a setting or configuration I’m missing?

Here’s a video of it:

I’ve attached the g-code (created by our in-house CAD/CAM, that I wrote the post processor for) - it’s the top surface of a foot orthotic.

Thanks for any insight - we’re in a bit of a bind here, needing to get this machine working ASAP.

As a first quick test I would strip the comments from every line that contains motion commands. try to use comments before sections of moves but not in a line with motion commands. it is not a very powerful processor and parsing all this extra text could be an issue. I’ve run 13+ hour v-carve jobs that had hundreds of thousand of short line segments without having this behavior and I’m running a 2019 3XXL.

Removing the commenting solved it! Thank you so much, Lester, I’ve been banging my head against this for hours!

Glad to hear it worked out for you. Looks like an interesting project.

Another area to check if it happens in the future is if your computer is updating Windows for the 100th time that week. Every time I get odd or jerky behavior, Windows is hogging resources with it’s umpteenth security update. :smiley:

Also had a similar issue when I had the Carbide Motion debug menu open.
