We don’t recommend removing the nozzles on our hot ends because it can cause damage to the hot end. The nozzle requires very precise torque and it is very easy to strip the threading on the hot end if over-torqued. We don’t want to encourage any procedure that can damage the printer. Be aware that any damage caused while switching out the nozzle is not covered under the warranty. For reference here is our disclaimer on attempted repairs or modifications:
WARNING: At Aleph Objects, Inc. we respect your freedom to modify your LulzBot 3D printer. It is important to know that any modifications or attempted repairs that cause accidental or intentional damage are not covered under the Warranty.
