The configured post-processing script does not exist: ArcWelder.exe
Hi, I have had this issue for a few weeks, I cannot print anything using PrusaSlicer due to this. I am not familiar with how slicers work and I need help.
It pulls up a message saying "PrusaSlicer has encountered an error. The configured post-processing script does not exist: ArcWelder.exe"
It does not allow me to download my gcode. How might I be able to fix this

Quite probably. The non prusa printer profiles are user submitted, so if your AnyCubic Kobra2 profile that you are using has any post processing scripts in then they did a piss poor job when submitting it. Sounds like they were using it and forgot that anyone else who uses it is not going to have that script installed. Basically post processing is done after slicing, the slicer calls an external program and runs it.
Arc Welder is designed to turn short straight movements (G1) in the gcode into a curve command (G2/3). Many older printers don't support G2/3 and Prusa Slicer didn't either until very recently. Remove any thing is that post processing field and save the profile again to get rid of it.
You can always add it back in later if you ever decide to install arcwelder.

Looks like you have something (i.e. "ArcWelder.exe") in Print Settings -> Output Options -> Post-processing scripts (you need to be in expert mode to see that option).
If you don't need that, just remove it. If you do need it, then either the path to the program is wrong or it is missing from your system, or there is some sort of permission issue.

Thank you, I do not quite know what ArcWelder.exe is or why I would need it. Is it possible that my presets from AnyCubic for my Kobra 2 are automatically enabling that?

Where can I find arcwelder?
RE: The configured post-processing script does not exist: ArcWelder.exe
pops up in a search.
Although I should point out that arc commands (G2/G3) are supported in Prusa Slicer 2.7, its an advanced setting, under Print Settings>Advanced>Slicing>Arc Fitting so the post processing script is not needed as PS can natively add them now.
