Before We Begin
Important Checks
Before you follow any tuning methods in this guide, ensure that:
- Voron V2: Your
gantry is properly squared. -
Everything is tight (seriously, check again) - Go back again and re-tighten every single screw you can possibly find, especially grub screws, linear rails, and everything in the toolhead.
- I do this once every once in a while, and I often find something that has shaken loose and is causing me issues that are extremely difficult to troubleshoot.
-
Your nozzle is not partially clogged.
- If your nozzle is partially clogged, you may not even notice. You may be able to print, but you will have an extremely difficult time trying to tune.
- Ensure that you can easily extrude by hand with the filament latch open.
- Ensure that the material falls straight down out of the nozzle when extruding midair. It should not shoot out to the side.
- Hit it with a nozzle cleaning needle just in case.
- If your nozzle is partially clogged, you may not even notice. You may be able to print, but you will have an extremely difficult time trying to tune.
- Your thermistors are the correct types in your config. Please double check them.
- Your motion components are clean, particularly between gear/pulley/idler teeth.
- Your nozzle is clean.
- Your nozzle has been tightened while hot (unless it’s a Revo), and is not leaking material through the threads around the nozzle or heatbreak.
