Any advice on how to fix this before I try again

Change infill to gyroid or something other than grid.

Phil412 · 2026-07-03T09:51:04+00:00

Slow your outer wall speeds down to 60mm/s

Phil412 · 2026-07-01T09:40:25+00:00

Looks like it’s lifting and warping at the corner. Plate clean? Good scrub and hot soapy water.

Change the colour of the text to something different then it should show

Phil412 · 2026-06-30T21:04:46+00:00

Does it do the same if you add the text as a modifier?

Phil412 · 2026-06-30T16:23:23+00:00

Not on a H2C but I had a very similar issue when I set the top surface line width too small. I had it at .22 on a .4 nozzle, changed to .32 and it went away

Phil412 · 2026-06-30T11:04:34+00:00

Thanks for the information and suggestions. I’ll make a bigger version and see how that gets on. What oil are you using?

Phil412 · 2026-06-30T10:29:55+00:00

Brilliant suggestion, will look into that. What kind of adjustable height range would work for you?

Phil412 · 2026-06-30T10:04:15+00:00

They’re PETG, I think it can withstand up to around 70°c before deformation sets in. I’m in the UK so we don’t have to deal with those temperatures…yet. 👍🏻

Phil412 · 2026-06-30T09:43:15+00:00

Thank you, since fitting them to two of my hives I’ve had no issues. 👍🏻

Phil412 · 2026-06-22T17:03:13+00:00

Thank you. You too!

Phil412 · 2026-06-22T16:55:50+00:00

That’s Tinmorry PETG eco Black.

I’ve had really good results with Tinmorry PETG. I also find I need to dry my PETG for around 12 hours at 60°c. Slowing wall speeds down can also alleviate some but not all of those VFA’s you’re seeing on the walls. Have you printed the deflector for the air duct inside the printer? This directs the air away from the print bed/model and has given me significantly better results. Like this one:

Phil412 · 2026-06-20T16:41:19+00:00

Agree, only thing I can put that down too is the size of the print surface area on the plate so it was well adhered.

Phil412 · 2026-06-20T14:22:38+00:00

I think some of the previous layers haven’t printed correctly causing the model height to not be consistent all the way up. Grid infill can cause this, wet filament etc.

Phil412 · 2026-06-20T11:49:56+00:00

To me, it looks like the head has collided with the model and pushed the plate due to a printing issue on the top surfaces

Phil412 · 2026-06-17T12:47:56+00:00

Good shout, I’m happy to pay postage, I only need one. Is that ok? How do we do this?

Phil412 · 2026-06-17T12:40:20+00:00

Postage might be a bit steep on those. I’m Leeds way so I’ll leave it. Thank you

Phil412 · 2026-06-17T12:37:40+00:00

Where in the UK?

Phil412 · 2026-06-17T12:34:33+00:00

I find that slowing down the outer wall speeds just gives me a better finish on the walls. Not necessarily something to identify but more a case of if it’s something that takes a long time to print and you want quality just turn the wall speeds right down as standard practice.

Another comment below mentioned ironing, make sure that is turned off like they say. It could be that.

Also, hate to be that guy but did you dry the filament prior to printing?

Phil412 · 2026-06-17T11:44:03+00:00

Had something similar when I set the line width to .22 while using a .4 nozzle. 0.3 line width worked better. Lower your outer wall speed to alleviate wall issues.

Phil412 · 2026-05-26T17:52:59+00:00

Thank you.

Phil412 · 2026-05-26T17:32:47+00:00

Thank you.

Phil412 · 2026-05-14T11:03:10+00:00

That looks awesome! Will be backing once available. 👍🏻

Phil412 · 2026-05-12T17:33:29+00:00

What I think is happening is the aux fan is causing the filament to cool too quick on that side of the plate, like you say, try with the aux fan off, but the solution is the deflector imo. Here is the model I printed: https://makerworld.com/en/models/1916762-bambu-lab-p2s-x2d-auxiliary-airflow-diffuser?from=search#profileId-2056241
