2 weeks ago I'm a fellow user who would also enjoy having a removal tab on the purge line. But going by the information in this thread: https://github.com/prusa3d/PrusaSlicer/issues/3123 that's not the remit of the slicer. The purge line is printer-specific gcode not dealt with by the slicer per se. If you happen to be using a prusa printer, the designers of the purge line might be down the hall, but the optimization target for that line presumably includes it staying put while any excess extrusion is dealt with, so introduction of fancy moves is probably asking for trouble. If you look around, you'll see that the XL has initial purge material hanging off the side of a tab of the bed; easy to grab. If the printer you're using has the ability to place the extruder off the plate, you could consider writing your own purge gcode to do that. If not, you probably have to focus on being glad that you have generally good bed adhesion? :) EDIT hold on, just looking at a MK4 slice here (I don't have a MK4) it seems to start the purge up the air over the same bed, which presumably starts it un-adhered and hence easier to remove. It's tempting to think maybe we could do that on a MK3, but it's a totally different extruder, and I bet they've tested the heck out of it. That makes me more sure that the purge line is the best available.
Is your feature request related to a problem? Please describe. I'm always frustrated when Its hard to remove the line that's printed in the front left of the build plate before the print starts.
Describe the solution you'd like Just add a small upwards movement at the start of the extrusion, so that there is a handle to easily remove the line.
Describe how it would work Printhead should do a small up and back down movement when doing the line, so its easy to remove it by hand later.
Describe alternatives you've considered start printing the line of the very left, so part of it hangs over the side of the plate.
Additional context Ive noticed with the 0.4 nozzle that often automatically ads a "handle" due to the extrusion that happens while heating, but for the 0.8 that almost never happens. it would be great if it just happens by design.
