Possible to print test line after colour change (before printing)
I have printed a couple of objects where I manually enter a colour change in PrusaSlicer for the last few layers (to accent my objects).
However, each time I do this, the first few seconds of extrusion is not perfect since the hotend has filament hanging out of it.
After a colour change, is it possible to perform a "line" of extrusion on the print bed, adjacent to my object, before the printer goes back to the object itself? Similar to the test line that starts each print. Thank you.

Yes, in theory, you could write some custom gcode but you must make sure to move the extruder to a clear area to avid crashing your print.
There is another way.
When making the colour change first reply No to the color check question to trigger a longer purge, DO NOT REMOVE THE PURGE YET.
Grip the longer purge extrusion (with pliers if a hotter print) and answer Yes to the second color check question; only when the print head moves away do you pull away the purge and you should get all of it.
Cheerio,

Fantastic. Thank you for the reply!

You can also add a small box to the right top of your model and use that as a wipe tower. Make sure in prusaslicer that the box is hit first after a color change.
