@OutsourcedGuru ok, I have found ArcWelder url
Do you use Prusa MK3 or MK3S printers? I see that G2/G3 is still experimental in Prusa firmware so I would not like to introduce something that will cause issues in reliability of my Prusa machines.
Mine uses a Robo board (Robo 3D) which is a common Reprap-compatible using a Marlin fork, so nothing special. You might try this on yours in the Terminal tab of OctoPrint to see if it behaves.
For me there is only one plugin that is most important: one of the filament-runout plugins (the one you like most). It is so helpfull to pause the printer when it runs out of filament when printing close to the end of a spool and just not have enough during the print.
Or instead of this the Filament-manager if you want to keep track of your filaments.
Just not at the same time as the filament-sensor-plugins as somehow they don't seem to like each-other when they run at the same time. I ran into strange problems while running sensor and manager together.
With the manager you do a more or less prediction about the amount there is left while the sensor-plugin's pause when you are really too late or have a broken filament between spool and sensor.
Both can be life-savers.
These are the only plugins that are loaded into my Octoprints on my printers at the moment (I run 3 or 4 instances, other printers use printrun on their pi's, so no plugins possible)..
Octopod! Not sure if this one counts since it really just facilitates connectivity to octopod.
Exclude Region - This one lets you cancels areas of a print if they fail. Super helpful for printing multiple parts and one starts failing but the others are fine.
GcodeEditor - good for renaming files or fixing a small error in your gcode without replacing and uploading.
