Printing 1.75 mm filaments using 3 mm printers such as Lulzbot TAZ 6 and Lulzbot mini

You can print with 1.75 mm filaments using printers which use 3 mm filaments by default.

The page will describe the methods by just using software and both software and hardware to get even more better results.

This is a very simple method with which you only have to change software settings in Cura Lulzbot.

. Change the print setup to custom.
. Find "Material" Settings.
. Change the "Diameter" to 1.75 as shown in the picture
. Make sure that the filament is properly gripped to the extruder motor before printing.

Changing the filament diameter in the software is the necessary step to perform for any of the hardware modifications.
Changing the filament diameter to 1.75 makes the extruder motor go fast and pull the filament faster compared to the 3 mm filament.
Since the heating block on the Lulzbot printers is designed for 3 mm filaments, the heating might be ineffective with the higher extrusion speed and having air in between the heater and the filament.
The problem can be solved by inserting a small piece of PTFE (teflon) tube inside the heater which has Outer diameter of 3 mm and inner diameter of 1.75 or 2 mm.
PTFE tube 3mm OD 2mm ID

This can also be done by changing the whole hotend and repurposing the printer to print only 1.75 mm filament.
