Pre and Post layer change

Recommended Posts

So in Cura, it is possible to write a special Gcode for pre and post switch extruder but that is only for a tool change. Is there a way to do the same for a layer change as well?

I am currently writing the Gcode for a better swiping mechanism to fight ooze during dual extrusion however I'm running into problems if the object being printed is the same colour for quite a few layers because there is no tool change and my 'wall' won't be drawn as a result. It would be best if the wall could be drawn after every layer change.

Does anyone know any way to do this?

Add the wipe and prime tower and you will get an extruder swap every layer, wether you want it or not...


I did just that and set the wipe&prime tower volume per layer to be 0.0001 in expert settings. That way it draws my custom wall every layer change and a negligible wipe&prime tower. Thanks for your input!
