A Post Processing script for Ultimaker's Cura to fix the issue with QIDI 3D printers with dual extruders
This script inserts a home gcode command (G28) into the gcode. It is inserted before the Cura automatic temperature setters.
Without this home command, the I-Fast will activate the extruder and, if not in the correct position, the extruder will bang against the printer wall.
- In Cura, go to the following toolbar menu: Help -> Show Configuration Folder.
- A folder should have opened, now open the 'scripts' folder, you'll need this for step 4.
- Close Cura.
- Place the file 'QidiDualExtruderFixForCuraV2.py' in the 'script' folder in Cura's configuration folder.
- Open Cura.
- Remove the bed and nozzle temperature setters and the purge line gcode in the start gcode or, alternatively, use the start gcode below these steps or in the file 'QIDI I-Fast Start GCode for Cura.txt' (for QIDI I-Fast only).
- Copy the first line of the start gcode, you'll need it in step 9.
- Enable this post processing script from the following toolbar menu: Extensions -> Post Processing -> Modify G-Code -> Add a Script -> Qidi Dual Extruder Fix For Cura .
- Paste the first line of the start gcode into the field 'First line of start GCode'. The default value for this field is "G28".
