G-code to clean nozzle after print ends (X1/P1)

Custom g-code to clean nozzle after printing is finished. Developed in OrcaSlicer for use in X1C but should be compatible with P1 series printers.  

The goal is to get nozzle reasonably clean after print. Especially helpful with “stickier” filaments (e.g. PETG). 

I have included a version that works with stock nozzle wiper as well as an additional one for “Nozzle Wiper V3.4” by Maleko (https://makerworld.com/en/models/437463-the-nozzle-wiper-v3-4-x-p-series#profileId-342665). 

You can find examples of modified machine end g-codes in the included filament profiles or attached text files. 

To implement, replace following line that turns off hotend in “Machine end G-code” with the provided code blocks. Below you can see the location of that line.

Notes 

• By default, nozzle is heated to filament extrusion temperature and parked over poop chute for 1 min to allow leftover plastic to melt. 
  • Alternatively, you can set to 250ºC ("common flushing temperature") or even higher to better remove debris. 
  • 250ºC works for wide range of filaments. 
• You can also add more wiping passes. By default, I have two rounds of wiping.
