Plugin or gcode adjustment

[DweedleDee 0]

Does anyone know of a plugin, setting or script that would make my nozzle go back and forth along a line before continuing, imagine a pen trying to make a heavy/dark line. So as it makes, for example, a circular path, it goes forward like 5mm, backs up 4mm, forward 5, back 4, etc. 

 

Does this already exist in some way? I basically want to do do multiple passes of material but quickly after each other.

Depending on how much you wanted, you could program it manually, although it would be a massive pain if your printer doesn't support arc moves.

 

But going back and forth along the same line? Bad idea. Especially if you're trying to extrude while doing it. If you're trying to extrude where there's already filament there's a decent chance you'll clog your nozzle. There's a very good chance you won't get the result you want.

 

Can we fake it? We could try, but I still wouldn't recommend it. If you increase and decrease the flow rate where you want heavier lines then it should give you thicker lines (and hopefully not expand upwards into a taller layer which would give you the same "trying to push filament out where there's no room to push" nozzle-clogging result). But that also means if you've got more than one wall on that section, you run into the same "there's already filament here" problem when it comes back to do the next one.

 

There's definitely not a setting for it in Cura. A plugin or script could do it, but it would be a pain. It's also worth noting that if your printer has a Bowden extruder, that will take a bit of time to respond to changes in flow rate to show up coming out the end of the nozzle. You could go into your gcode and add some flow rate commands manually although obviously if it's a big print that becomes annoying fairly quickly.

 

Basically what I'm saying is the best way to do it is make the thickness changes in your model, then enable Top/Bottom > Enable Ironing to get a nice smooth surface.

I didnt want to say too much to begin with but its without extrusion, just heating along the line for heat transfer

Look into the "ironing" feature in cura.
