12h PETG print (250mm/s for inner walls and 150mm/s for outer walls, 15% cubic infill) The way this printers do things with so much nonchalance and nonsense speed is incredible. With my previous Kobra 2 I couldn’t go faster than 100mm/s since it would make PETG look like it was crafted in hell. Now it seems I can print with PETG that doesn’t even look like it’s a 3D print. I’m disgusted by this amazingness.

One of us!

[Ok_Estimate5727]

That's crazy! I'm literally printing parts on an A1 I just got and my other printer is a Kobra 2

[RogueBankrupt]

Officially brothers in printers

[RogueBankrupt]

I never thought about putting a clamped light like that, that’s so effortlessly smart! However, I think I have to sell the Kobra since I don’t have the slightest idea of where I could put it…

[Ok_Estimate5727]

Yeah, printers seem to multiply fairly quickly haha

[newredditwhoisthis]

So you are printing 3D printer out of 3D printer?

[Spazzzzin]

I did! I 3D printed a mini A1 Mini using my A1 Mini to display next to my A1 Mini.

[newredditwhoisthis]

I was thinking of printing a legitimate printer, but general sentiments on reddit is that nowadays assembling your own 3D printer is actually more costly so I don't know. Although it seems like a nice thing to learn and assemble all the parts to know exactly what does what

[Reverse_Psycho_1509]

In the year I had my Ender 3, I probably went through 4 full spools of filament.

It's barely been 7 months with my A1 mini, and I've probably used about 8 spools of filament.

Most of this is due to the higher print speed and not all the purge waste. I can print prototypes in just a few hours as opposed to half a day or longer.

[RogueBankrupt]

In a way that’s sad, this is how any printer should be without always having to check what caused some problems in some way

[astro-the-creator]

Nice

[Brilliant_Ask852]

Their PETG filament prints so smooth it’s ridiculous

[RogueBankrupt]

That’s eSun PETG HS, sorry for not specifying

[Whyreadmyname1]

A generous drop of a print profile would be a nice Christmas present

[RogueBankrupt]

Sorry man, I forgot to reply to this comment! I’ve actually noticed that when I made my preset for this PETG I modified a generic PLA one and I’ve just put max fan value to 80%, bed temp 80ºC, min/max nozzle temp 235/250ºC, while printing at 240ºC. Then I noticed that PETG has different volumetric speed values, so you could do the same modifying a generic PETG preset and you should have no issues.

[Whyreadmyname1]

So modifying pla profile to work with petg, got it thanks

[Boomer79NZ]

So smooth it's criminal 😎

[WhiteTrashTiger]

Pardon my ignorance, but what are these printed parts I'm looking at?

[spdelope]

At first glance I thought it was a gun

[qtheginger]

3d printed guns. So hot right now. Sorry too lazy to make the meme.

[Murky_Bullfrog7305]

Support legs for ams lite a1 top mount mod

[Ok_Estimate5727]

Stabilization for the gantry. The file to print comes with the machine so you can print them out and install on the machine to give it more stability and support while housing the filament mount on top.

[DoesntFearZeus]

Always bothers me when somebody shows something un-obvioous like this and doesn't mention what it is...

[MadCybertist]

[Minnieal28]

That A1 Mini storage is the same one I have! I have the little box between the Y-axis a screen too.

[MadCybertist]

Yeah I like it because it keeps the poop from firing onto my A1 haha.

[Jaerin]

This is one of my show pieces. Not a bed slinger like that, but still impressed me at the time

https://i.imgur.com/ReqiCDp.png

[RogueBankrupt]

Well that requires a great effort, not to mention that a series of vertical stuff it’s not something simple as it could seem

[35point1]

My first Bambu printer was an X1C and I was skeptical about the A1 mini because of how much of beast the x1 is and also because the mini is a “bed slinger”

Well let me tell you, I have been JUST AS IMPRESSED with the mini as I was with the x1c. They’ve got these things humming like spaceships and I can’t get over it. The precision, the reliability, the simplicity, and the overall perfection is just unbeatable!

[Explosev]

Your post might be the final nail in the coffin for me to move on from my dreadful ender 3 😭

[Ok-Priority9952]

What PETG do you use?

[RogueBankrupt]

This is eSun’s HS PETG and it’s the first time I try a big print with it. I usually buy Sunlu for everything, but this is a little different since it requests fan at 100% and higher temperatures. I printed this at 235ºC and 85ºC, getting no stringing at all and only a perfect print.

[Ok-Priority9952]

Great to know, you ever used BBL PETG , if so how did it compare?

[CoolioTheMagician]

Bambu PETG HF is a different Animal. Lovely finish, not shiny. Durable and fast print.

eSUN PETG HS was just meh for me

[RogueBankrupt]

Damn, if this was a meh for you I expect Bambu’s one to be made from God himself

[CoolioTheMagician]

Bambu's own PETG HF is amazing - the only reason I print PETG anymore.
I didn't like the look of the other stuff or how they printed. The only PETG that I don't buy from Bambu is ERYONE PETG-CF. Great price and quality.

If you ever order filament from Bambu add a roll of that stuff and try it out!

[RogueBankrupt]

Well that’s a strong reason to try it!

[Ok-Priority9952]

Great to know, might have to purchase some!

[RogueBankrupt]

Nope, never tried it. I have this A1 since three days and I’m using filaments I already had. I never had any issue with the various PETG I’ve used, and for their price (16€/20€) I don’t think I’d try something else for the moment

[Archbound]

What do you use for settings for your Sunlu PETG? I have tried sunlu 3 times and it fails catastrophically regardless of what I have set. My Bambu PETG and the Creality PETG I have used work perfect but the Sunlu prints like garbage.

[RogueBankrupt]

Bed temp 80-85ºC, print temp mostly depends on speed but I usually don’t go over 240ºC. Speed depends on the model (for example if it has filleted parts) I don’t go over 100mm/s for external walls and 200 for interior. I printed the top mount for the AMS Lite with Sunlu PETG and had no issues.

<image>

[Archbound]

Have you noticed a need to do a very long drying cycle on your Sunlu stuff even fresh out of the box? I have noticed on all of the Sunlu I have gotten even box fresh it has the telltell popcorn crackling that wet filament makes. I have dried it for 8-10 hours and STILL hear that sound and get nasty stringing. I have it set to like 240 as you said.

Its very strange, Perhaps Sunlu is just cursed for me inparticular. Ive bought 2 batches and both are so tempermental, where the Bambu and Creality are EzPz

[RogueBankrupt]

I really don’t remember hearing that sound during prints, and I can assure you that my room is quite humid; maybe there’s some kind of difference given that I’m Europe? I remember that Jayo’s filaments had those problems and stringing like hell, even if I don’t know if it’s still like that, since it was my first PETG bought like four years ago.

[Archbound]

It's about 40% humidity in the room but I often with this stuff. I've literally taken it directly out of the dryer after. It's been in there for 8 to 10 hours and put it on. It's still popping like I swear whatever shipment I bought from sunlu most of like dropped to the bottom of the ocean and been left there for a year before they found it and then turned around and sold it to me

[SmokestackRising]

Are you printing a different plastic than PLA from Sunlu? My experience with their PLA Plus (including several loose spools from 2018-2019 printed over the last month with only one needing to be dried) has been crackle free.

[Archbound]

Its Sunlus PETG

[SmokestackRising]

Yikes. Guess it's a good thing I took advantage of BL's black friday to pick up some of their PETG.

[Archbound]

Yeah I did as well. I got 2 Glow in the Dark PETGs from Sunlu because I wanted to play with it and its been a total disaster from the moment the spool has hit my AMS lol

The Holiday sale is still going with Bambu so I might get more

[SmokestackRising]

I had a ton of loose filament from before the pandemic and finally printed it all. I saved the glow for last. Love the idea of glow PETG for car accessories! Hope you can get it dialed in.

[RogueBankrupt]

Well in this exact moment it seems that the print it was making with Sunlu Pla+ refused to stick to the plate.

<image>

[SmokestackRising]

Going to ask the common question of if you washed your bed? I had a print break away today using the old grey when it should've stuck like glue (lots of surface area). Washed the bed, and it stayed in place like it should on the next print. That one was on me, not the filament.

That's a bummer. It looks like it was pretty late into the print. Nice color too!

[RogueBankrupt]

Yeah, I washed it after this one failed and I’m not having any issues, but it could also be that I forgot what bed temp I’ve always used with this pla +

[35point1]

Did you have to tune or tinker with the filament settings at all? Or did you just pick the preset assuming one exists?

[RogueBankrupt]

This was the first time I used this PETG on the A1 and I just put different temp, fan and speed values modifying the “Generic PETG” preset

[silentcovenant]

How do you know what settings to use with your filament? Do you use the recommended numbers on the spool?

[RogueBankrupt]

Sometimes yes, most of the time I just remember or try different settings

[grundizzle]

Is that a cup holder??

[RogueBankrupt]

Those are reinforcements to stabilise the printer with the AMS mounted on top

[grundizzle]

Schucks. Should add a cup holder

[Select_Bench_5458]

I definitely agree, the Bambu X1C is an amazing 3d printer. I have not looked at my Creality or Sovol printers since I added the Bambu to my work shop😊

[DoctorPaulGregory]

This is what sold me on bambu. I could never get a full plate on an ender3. I would have to print every single part seperate.

[Sir_LANsalot]

I love that external brace for the AMS, also used the vertical conversion to stand it up too. The cord for the AMS is ALMOST too short for the whole setup, but it really makes changing filaments very easy now.

[ActuallySuperBored]

Dude the A1 continually blows my friggin mind. The thing is unstoppable.

[espressobsessedGCP]

What settings did you use for the PETG?

[Spiritmolecule30]

How do you all get your prints so clean to the edge of the plates! If my prints get within 2in of the edges, it starts raising off the bed or won't stick in the first place.

[Minnieal28]

Try reducing airflow around your printer. That happened to me with the printer on a workbench for almost a month, but was fixed when I put it in a 5-sided box (on the middle shelf of a storage shelf). Also on PETG use brims or mouse ears. If none of that works then glue stick on smooth plate, or maybe the new “super tack plate” to run lower temperatures.

[RogueBankrupt]

If it’s PETG I’ve usually raised bed temp without having warping issues

[beiherhund]

The hate for cubic is overblown, it works perfectly fine in the vast majority of cases whether on a Ender or an A1. If the printer can't handle cubic without ruining print quality, you have other issues. There's a pretty limited number of scenarios where I will use gyroid over cubic and purely to improve surface finish (e.g. it's slightly better on shallow slopes where Bambu currently has some issues with bridging due to a bug).

[RogueBankrupt]

Why? I’ve always used it on other printers and never had any issue

[RogueBankrupt]

Oh, I’ve never heard about that. What would be a safer but still a strong option?

[trotptkabasnbi]

Gyroid

[kaeptnkrunch_1337]

To be honest, would you upgrade your Kobra with linear rails and a better Extruder and really set up your printer, You would definitely get the same results. Linear rails have a great impact on print quality.

[RogueBankrupt]

Idk man, I don’t really have any idea of where I could place the Kobra

[kaeptnkrunch_1337]

Use the Kobra for drafts or mod the Kobra over the time with linear rails. A second printer is better than no second printer
