Best practices on how to change nozzle on the Zero

Sovol Zero

Hello,
what is the temperature I should set the hotend, before unscrewing the nozzle?

And what is the torque I should use, at that temperature, while screwing in another MK8 nozzle?

Any hints or tips? I’ve never done before, and I guess other people will find themselves in the same situation, so this thread may be useful in the future for many.

Thank you very much.

Can’t tell you torque values but here is what I do.

  1. unload filament.
  2. set nozzle temp to 220c
  3. let it reach temp and leave for 2 mins
    Take an adjustble spanner to hold the block directly above the nozzle BUT do not put the adjustable spanner on the part of the block that holds the ceramic heater or you will break it (ask me how I know). Take your nozzle spanner and loosen/remove the nozzle (you will feel how tight it is)
  4. Nozzle will be very hot so mind your fingers.
  5. screw in new nozzle
  6. use same spanners to tighten (to approx the same torque as it took to undo)
  7. needs to be tight to prevent any leakage.

Hope this helps.

Sovol makes several marketing videos every day, usually silly/fun stuff. They should make a short video showing their procedure for changing the nozzle on the Zero and SV08 Max. Their technical videos have been very helpful in the past but they haven’t made any lately. I assume the engineers that make those videos are busy and haven’t had a chance to make tech support videos.

I talked to Sovol last week about making a video for the Zero…
I think one might be coming sometime this month.

Sorry for the late reply. We have reported this issue to the after-sales department. They have received fewer complaints about the nozzle. If possible, you can send an email to info@sovol3d.com. So they will see more requests and make relevant videos.
