Which torque is correct for a nozzle swap?

Recommended Posts

Posted · Which torque is correct for a nozzle swap?

Interested in feedback from people who successfully swap nozzles in their Olsson Block.

Ultimaker suggests tightening the nozzle with a torque wrench set to 1 - 1.5 Nm.

According to Anders Olsson, the torque wrench print will apply 0.25 - 0.5 Nm.

Does anyone with experience have feedback as to which setting is more reliable? Or does it not really matter?

I have printed the Anders torque wrench and have had no issues with leaking.

Ultimaker experienced some leaking when they were testing the Olsson Block before they sold it on there printers, so they recommend a higher torque setting.

I am using the old UM feeder and Roberts feeder. If you use the new geared feeder or something like the bondtech then it maybe more likely to leak with the higher pressures in the nozzle.
