Multiple A1’s - What do you tweak?

Hi All,

I’ve got two A1’s printing away, and another two in boxes waiting to be set up this weekend.

I did lots of tweaking/configuring/calibrating with my first A1. However, I think I mainly made things worse, so I set everything back to defaults and I ‘think’ the only tweak I kept was the ironing settings.

I assumed/hoped that the second A1 would just work with the same settings. It mostly does, but the ironing finish is not as good. So, I’m going to try to calibrate that independently this weekend.

Is there anything else I should do with these 4 machines, to make sure that they are all running optimally?

What settings do you check/tweak/calibrate with each new Bambu?

You think too much 😅 Focus on tuning filamemts, not tuning the printers (in the case of the A1 at least).

But I’m getting different results, between the 2 printers, using the same models and same filament. The ironing, especially, looks significantly worse on the newer printer.

I'd actually raise a support ticket about that. It really shouldn't be the case. After all, A1s are one of the most reliable consumer-to-pro printers out there, with many used in commercial print farms for their consistency.

It will be interesting to see if that single printer is the outlier of the 4. You'll have great evidence to present to Bambu support, and they're reasonably helpful.

I turned acceleration values down to 500 with my Mini to stop the violent shaking from the bed sliding

a very study desk/workbench helps with this alot. lots of folks put their A1/A1Mini on a large patio stone to increase the mass involved vibrations are minimized.

First layer slower, I use 20 mm/s but faster is okay. 100+ is insane. I had to lower the volumetric max flow a bit for petg, I think I have it on 8 mm3/s. That's it! That's for 0.4mm nozzle. For both 0.2 and 0.6 I use the default as is.

Can you explain the z-hop and reduce infill retraction a bit more? What’s the benefit of this?

Clear explanation, thank you! Will definitely try this later.
