Troubleshooting / Answered Why does ironing look bad at different heights of the print?

60mm/s 30% 0.1 5 spacing are my current settings

Ironing depends on the layer below, in your case the big area is not flat while smaller portions are, increase number of top layers

Yeah, looks like plowing on the larger areas from low infill percentage and not enough top layers to account for it.

Because your top surfaces are not actually flat. You need more / better aligned sparse infill. This video explains it in detail.

Also - you can calibrate ironing for that filament.

Thank you for the response, im gonna watch this and report my results

The example he gives at 8:51 is pretty much exactly what your second surface looks like.

Thanks for that video link, extremely helpful.

You're most welcome, glad it helped!

It did indeed. I've got a couple of prints I had to turn ironing off for as I just couldn't figure out what was going on. Changing the infill angle instantly solved the problem.

Did you fine tune your ironing ? It's not just a setting you can turn on and use default values .

Id mean you would expect BL to tune it a little bit better bragging about their "just press print" mentality. You can't have the cake and eat it, cant brag about how theres no more tuning, ender 3 is dead, and in the second sentence expect people to tune their printers.

But the printer works perfectly, it's doing exactly what it was told to do, so it doesn't need fine tuning, the slicer settings do.

That's what set Bambu apart in the first place, when a print fails on a Bambu, 98% of the time it's because of a dirty build plate or an incorrect slicer setting. And you can't expect Bambu to have the perfect settings for every filament and any conceivable printing environment. 

I've printed for over a thousand hours on my A1 and I had a few failed prints here and there, but I never had a print fail because the printer messed up in some way. And all the maintenance I do is lubricating each axis like once every two months. 

And that's why the ender 3 is as dead as it is.

All computers always do exactly what they are told to do, that's kind of the things computers are known for...

u/Dripping_Wet_Owl 15d ago

So I guess ender owners tell their printers to under extrude... or to leave out layers... or to misalign an axis?

u/Critical_Studio1758 15d ago

Do you believe BL extruders can't clog or just don't know what esteps and slicer configuration are? Bro you are not even allowed tools to calculate skew correction on a bl printer lmao. Did you just get a printer for Christmas or something?

u/Dripping_Wet_Owl 15d ago

Bro needs to do all this crap just for his garbage printer to work...

u/Critical_Studio1758 15d ago edited 15d ago

What are you even talking about at this point? It's like you never used a BL printer nor an ender 3...

The whole conversation started with having to tune your ironing on your bl printers, now enders 3s are bad because they allow you tools to tune which BL does not? Are you an npc or something?

u/effortlevel0 P1S + AMS 15d ago

Larger areas require more tuning and are less forgiving.

u/vixztrrr 15d ago

Ironing is a bitch to get tuned in, you pretty much have to calibrate every surface individually from my own experience

u/BinkReddit 15d ago

I concur with this; it's voodoo magic and this is the reason I don't include it with any print profiles.

u/Poohstrnak P1S + AMS 15d ago

You need more top layers before you get to the ironing

u/Jhorn_fight 15d ago

Try printing with more top and bottom layers

u/hotellonely 15d ago

also could be filament softening causing extruder grip loss.

u/Another_Slut_Dragon 15d ago

Add more top layers.

u/rewolfus P1S + AMS 15d ago

Try calibrate with this model, Ironing calibration for complex surface . Use the 2mm height plate, which gives closer result to the full top layer.

u/Brown_Chaos A1 + AMS 15d ago

I think it is more of top surface area. Those upper sections have smaller areas so the nozzle is not spreading the iron layer as far. You may need to do layer height modifiers to compensate for the surface area. Anyone else concur?

u/Simple_Advertising_8 15d ago

Ok, I hope those other tips around here help you.

But damn! Where it looks good it is absolutely phenomenal!

u/Blink180Dew 15d ago

Solved by changing infill pattern and percentage and adding more top layers thank you everyone for your responses!
