Cura Tool/Nozzle Change Script

Posted (edited) · Cura Tool/Nozzle Change Script

In dual extruder printers, we often face problem related to oozing and this lowers the quality of print leaving the debris on to the walls of the print. There is no inbuilt feature in Cura to avoid this problem.

Although there is ooze shield and prime, but it is a waste of too much filament.

The clear benefit of this script is near elimination of oozing and depositions on the print. This script moves the print head away from print while changing the tool and wait until it reaches the desired temperature. Also lowers the temperature of another tool. The drawback of this code is too much time wasted in changing temp and waiting.

These codes should be insert in Settings > Printer > Manage Printers > Machine Settings. Then Extruder 1 and Extruder 2.

Extruder 1 & Extruder 2 start code :

M109 S210 //To set the temp of active tool at desired printing temp

Extruder 1 & Extruder 2 end code :

G0 y0 F4000 // To move the print head away from print

M104 S150 //To set the temp of inactive tool at standby temp

Also you can add a mechanical wiper made of steel wire or silicone to wipe the nozzles near standby position.

(This code is for third party and DIY printers.)
