UGS sent previously opened file, despite showing current file

What happened

I'm CNC carving a long piece of wood in 5 sections. I've got 5 different NC files: section-1.nc through section-5.nc. I'm working from 5 down to 1 just because that setup was easiest. Sections 5 and 4 worked fine. I remounted the piece for section 3 and just before I started it, realized I still had the section 4 file open. I loaded section 3 and then ran it.

For some reason, it sent the section 4 file instead of the section 3 file. The messages.log talks about loading section 3, but it sent section 4.

What it carved:

What the UI showed

sections-3-4.zip

Note: I'm using GRBL, but I'm not sure which version.

How to reproduce

I haven't figured out how to reproduce this.

Your version of UGS is ancient and I would recommend that you upgrade and try again:

The other thing that I notice is a large amount of errors in the log. Do you perhaps have a offline controller connected to the machine?

[MikeBenza]

I'll try upgrading when I get back to it in a few days.

I do have an offline controller. I wasn't able to (quickly) figure out how to set up my z probe in UGS, and I preferred the continuous jog on the offline controller (I was much less likely to make a mistake in it than in UGS).

Using an offline controller together with UGS may have undesired side effects.

UGS keeps track of all commands it sends and the responses. If you have a secondary unit that also sends commands UGS will get confused.
