Is it possible to return to a layer height in cura after running a nozzle change?

Recommended Posts

So here's the thing, I'm trying to print with 2 extruders and one nozzle. I already got close and uploaded my progress to thingiverse http://www.thingiverse.com/thing:1494026 but now i'm trying to get cura to wipe the nozzle off after purging out the old color. the problem is that if I move the z axis to 0 it won't move back to the height of the current layer. Any suggestions would be greatly appreciated.

this is the code I have so far


;Switch between the current extruder and the next extruder, when printing with multiple extruders.;This code is added before the T(n)G91                                    ;relative positioningG1 E-1 F6000                            ;retract the filament a bit before lifting the nozzle, to release some of the pressure;G1 Z+0.5 X-20 Y-20 F{travel_speed} ;move Z up a bit and retract filament even moreG90                         ;absolute positioningG1 X221G1 Z0G92 E0G1 F10000 E-155G92 E0

The brackets after z is where the issue is.

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
