solved machine has no arcs

[bespoke]

A really long time ago I built a optical inspection machine. It has been gathering dust for 15 years, so I decided to toss the optics and bolt on a cutting head. The issue is that optical inspection doesn't need to ever move in arcs. No G02 and G03. I can fake linear motion by setting each X & Y stage to the appropriate ratios of acceleration, distance, and velocity, but I have no idea how to deal with arcs. Is it possible to disable arcs in the g-code and have dxf2gcode only use linear motions?

Hi,
yes that's possible. Just check the postprocessor settings on the page "software configuration". There you will find the option to do so.

I see an option for 'only counterclockwise arcs' and another for 'maximum arc radius'. I don't see one to not use arcs at all. Would I set the maximum arc radius to zero?

 

[chrisko]

Which version do you use, i use the newest one from development: dxf2gcode - Browse /Development at SourceForge.net
Not sure when this option was added

For option see figure below ...

I have many fond memories of 2017. This is the version that is in the Ubuntu repositories. Is there an Ubuntu-style PPA or a Debian package built anywhere? I would rather leverage that effort first if it available, rather than building from source.

Did you try the latest one of the sourceforge network. It might have found It's way in there already. If not, you need to wait ...

You can try with the installer. Howto - Howto install dxf2gcode

Installer is compiling, and sourceforge has source. Well, at any rate, my question is answered and I will attempt to mark it so.

Thank you spicer to jump in here. I did forget to mention the installer, sorry ...

Asked about why Ubuntu is so out of date:

From:Thomas Ward <teward@thomas-ward.net>
In actuality, the current version is 20191025-2 from Debian synced into Lunar during a time period of which between 2018-04-24 the package was last updated and now a newer update made in November of 2022.

"dusty" only applies to where the version is the older 20190925-4 version from 2018, and during the time between 2018 and 2022 the package remained in ubuntu because it was synced from Unstable and did not get updated then.

There remains cases that this package is not maintained consistently in Debian namely due to the fact that upstream doesn't seem to regularly produce code versions for updating. If you need the newer version you might want to consider updating to the 23.04 release when it's out. Otherwise you'll have to stick with the 2017 package version that is available in the version of Ubuntu you are using.

So, a more up-to-date version is in the unstable branch and working it's way into the next release.
