Sudden slowing feedrate

for some strange reason, my feedrate has slowed down drastically while in the middle of cutting a project. I double checked the toolpaths and tools selected and there is no reason for it to be suddenly slowing down. i’ve even clicked on reset feedrate while in carbide motion but has no effect. has anyone else encountered this issue?

Can you post your g-code file for a check ? it may be a vector that’s made of a very high number of tiny segments rather than longer lines/curves

Do you have the Log window open? Which version of Carbide Motion are you using?

So it kept going at a slow speed rate even after deleting and recreating the tool path. it is a simple rectangle pocket. it was strange because it was only doing it with that particular one (although i had 4 other identical with no issues). i ended up slightly resizing the vector and it ran through without problems. not sure what was going on

I have experienced a situation that sounds similar. But I assumed I stumbled onto a bug so obscure it wasn’t even worth reporting. Do you think you did the same thing I did…

I had a toolpath that had a start depth of 0.0000, and an intended max depth of 0.0001. But I had entered one too many zeros (0.00001). That cut may look stupid but this was my method of surfacing material that was slightly thicker than 0.50" to a precise 0.50" using Z set to the bottom of the material.

When looking at the toolpaths, Carbide Create draws that cut so there was no visual indication that I had done anything wrong.

But when Carbide Motion ran the job it slowed to a crawl while positioning for that first toolpath, when it finally got to that starting point it then skipped that toolpath and moved onto the next one and resumed normal speed.

Did you keep the faulty gcode file for a look?

I’m not sure how to do that… my guess is that it’s no longer there since I deleted and created a new toolpath?

If you re-saved the toolpath to the same filename, it’s not there anymore. Ok, this was just for a check, but everything seems to be in order now, no worries.
