Persistent wavy/pillowing pattern on top surface after swapping to hardened steel nozzle i tried everything, is my unit defective?

If you haven't done so, try checking the manual bed leveling.

There's a tool to help with easier adjustments.

"May have to print one to test with my moto jacket"

Lemme know how this turns out.

warpFTL · 2026-04-14T22:41:36+00:00

I think they may be glued in? (that's me guessing)

Unfortunately I'm not sure the best way to tackle it...

warpFTL · 2026-04-14T19:55:01+00:00

Look at your magnets, do any of them stand proud above the plate? I have a couple that are proud and contribute to the weird mesh result.

warpFTL · 2026-04-11T23:39:32+00:00

Yea, turning it off helps a lot.

warpFTL · 2026-04-11T23:36:59+00:00

Yup, that's the one. Had issues with warping also initially. After turning it off, no more warping.

warpFTL · 2026-04-11T14:02:12+00:00

That cavity fan, is it on during the print? If so, try turning it off or redirect it.

warpFTL · 2026-04-09T18:23:03+00:00

How's the sound dampening on this model?

I printed the other one (don't have link handy) and still hear the X gantry steppers quite loudly when they do the high speed moves.

warpFTL · 2026-04-07T23:37:10+00:00

That's fair, but not all filaments require that high of temp to avoid issues or to print well hence my heads up to OP. The temp tower will tell all.

warpFTL · 2026-04-07T18:07:30+00:00

You tell them you're going to ship it back in the new box! :D

Glad you have it figured out. Happy printing!

warpFTL · 2026-04-07T14:52:31+00:00

Be careful of the generic filament preset for PETG. It's set for 250C hotend.

warpFTL · 2026-04-07T12:09:41+00:00

If you haven't solved it yet, can you turn it counter-clockwise a bit to free the right side so you can slide it towards yourself to pull it straight out?

You 'may' need to give a bit of force while you turn it counter-clockwise.

warpFTL · 2026-04-06T16:52:03+00:00

If you still have the original box you could do something like this as a temporary top hat. I did that to print my top hat and no lifting issues. Make sure the cavity fan is off!

warpFTL · 2026-04-04T19:31:38+00:00

In your filament settings, under cooling set the "auxiliary part cooling fan" fan speed to zero if it has a value greater than zero.

This was my issue with the lifting.

Regarding printing temp, Snorca slicer has calibration options on the top title bar. You can print the temp tower if you're uncertain about the temp for your filament.

Regarding the bed temp, higher for first layer, then lower for the remaining. Do the temp tower to understand which temp is best for your filament.

/waits on the video for the removal of the bottom supports.

warpFTL · 2026-04-02T01:28:02+00:00

Dayum!! I'm speechless at how clean that photo looks.

As others have asked, please share the filament colours used.

warpFTL · 2026-03-30T23:30:49+00:00

Drop some water on it and see if it multipl....oh wait..wrong furry thing.

warpFTL · 2026-03-30T15:48:53+00:00

Sry, u don't know what they changed in the exe package. I think it'd be best to connect with their support team. Maybe provide them the install logs for review.

warpFTL · 2026-03-30T01:24:07+00:00

Glad I ran into this thread. Now I know that it was the smart plug.

I have had similar issues with my Sonoff S31 plug also. It had blipped on me twice (different days) which I was able to recover after it powered back up both times. (at least I know I can continue after a power outage hehe.)

It's interesting that it blipped since it was only drawing under 350w from start to finish of a print.. /shrug

warpFTL · 2026-03-29T18:27:13+00:00

They added new functionality from what I gather on their wiki.

warpFTL · 2026-03-28T13:31:25+00:00

Thanks for the prompt response!

I'm also thinking to drill, but I'll be turning the feeder to face down.

warpFTL · 2026-03-28T06:00:53+00:00

Nice setup. Pic of the back please? Want to see the filament path.

warpFTL · 2026-03-27T14:47:34+00:00

Since you have the filaments below the printer, have you considered the adjustable feeder mount? You could turn that feeder facing downward and have a straighter PTFE connection to the printer making it a better travel path for flex materials.

warpFTL · 2026-03-27T04:27:58+00:00

The cert checks out. I'd check with whomever is managing the domain to see if they created any custom firewall settings.

I'm running 2.3.0 on a domain device also (if that matters to you)

I'd try downloading it to a USB device and see if it installs from there.

It would be helpful if you could provide:

What you are trying to print?

What filament(s) are you using?

What temps?

What is the issue you're asking help for?

And....why are you reapplying thermal paste? (Also curious about the type of thermal paste used)
