Nozzle not lifting all the way

Postby mdana » Sun Feb 09, 2020 7:40 am

The right nozzle is not lifting all the way when switching from extruders. I have verified that the entire filament path is clear of clogs and that the heat sink is not interfering with the servo housing and wires. Lubricating the lifting assembly helps for a while, but it seems like the spring is not stiff enough to reliably lift the nozzle over the course of a long print.

Would you like to take the three fans off and share us some pictures around the hotends?
And please let me know whether the shifting works with hotends removed.

I was able to fix the problem by disassembling the lifting assembly and cleaning the blocks and springs (there was sticky grease on the back of the blocks).
