Error 26 & 36 midway through cuts

Hi, I’ve been running into random glitches/feed-stops when cutting, flagged as GRBL error 26 or 36 around line 1790. What’s especially strange is I don’t see the lines showing up in the console within the .nc file. I should note that the attached screenshot is from after trying to resume from line (after the issue first occurred).

I’ve also noticed some errant moves that are not showing up in simulation, could there be something messing with the communication between my laptop and the controller?

I’ve been messing around with this more and I believe it’s partially due to the gSender ā€œRun from lineā€ feature. No matter what line I choose to start from, I get this error, perhaps due to the ā€œG3ā€ line being sent with no further parameters.

If I try to just run from the start, I don’t get this error.

@espresso-shot I’ve moved your topic to the gSender category, since you’ve now shown that the problem only arises when you are using the start from line function in gSender.

@espresso-shot we made some improvements to the start from line features as of the new 1.5.# versions, have you given the new ones a shot yet and seen improvements?
