I have just got my bad boy mini A1.
I tried several benchies (g code that come with A1 mini’s stock prints) with 3 different filaments, including the inbox 20gram one.
I have noticed some repeating problems. Could you guys give me a helping hand here?
I have done all the calibrations in the maintenance section, and also the two printing calibrations in the bambulab desktop app.
All the materials are PLA
If your Benchy takes less than about 1h 30m, you are printing a fast Benchy.
Modern printers like those from BL will be able to print a fast Benchy, even a super fast Benchy taking less than 20 minutes.
However, there is a point where you will start to lose some quality as the speed hits physics.
The Benchy was originally designed to test the capabilities of a printer and would often fail because of it as earlier printers had many limitations.
If you print a Benchy that takes around 30 minutes, on a BL printer, it should come out fine.
If you print one that less time, it will have some minor issues. The fast Benchy prints are torture tests for the printer.
Print one of the other models from the SD card or from the Bambu Handy mobile app and see what the quality is like. Chances are you are getting stuck on expecting perfection that is by design not expected to be when running at sub-20 minute prints.
Did you go though the setup at the beginning? It takes around 10 min,.
Yes, I did all the setups
I will try to print a slower Benchy that I sliced myself
Enable the Flow Dynamics Calibration.
I got my A1 a few days ago.
The 14min Benchy came out absolutely flawless with the PLA Sample which was in the box! I was blown away! So don‘t try to slice yourself. The problem is not in the GCode. For me it looks like a Pressure Advance Problem. I use Flow Dynamics on every print…
I use it in every print too, including this one. Sadly that one isn’t my problem it seems.
If it were me, I would have stopped when the first benchy didn’t print well using default setting, meaning after the initial setup is done, just select the benchy, then hit print. I would have contacted the support right away. If support couldn’t figure it out either, I would ask for a replacement.
See if you can reset the printer back to the same state as when you received it, and give it a try again. The benchy should come out pretty good, an indication that you received a working printer.
Should I just make a ticket?
Yes, absolutely, if you haven’t already. The reason to get a BL printer is so one doesn’t have to manually calibrate this and calibrate that before being able to get a good print. It should print well out of the box (follow the instruction to complete the initial setup though.But don’t do anything else, leave everything else at default).
@Arpaworks how did it go? I am also having some issues with the SD card benchy on an A1
I’m having the same issue to, how is it going to you? I still didn’t open a ticket @barbaccia
remove the nozzle and check the three little black screws, It quickly looks like the nozzle is loose or the nozzle is wobbling
Only just got my first 3d printer but used to use them at work.
Deifnitly make a support ticket. Afaik the print loks like the cooling fan may not be working/blocked/faulty as one possible cause to the severe sagging. As I say no expert but can you hear the fan as its quite noisy at maximum during the bridging sections.
I tried to completely reset my printer and I did new calibration ecc…
I printed another benchy, this time is better, but not as the one that I see on videos on yt.
Fan work well as I see, anyway I will open a ticket now, I will tell some news later
other nozzle or make shure all screws on the print head are tightened
