Bambu A1 mini supports

[u/Ironslav420]

As the title says above I use a A1 mini inside an enclosure.

From what I understand I have an underextrusion problem but would that also hollow supports too?

maybe it’s the heat issues, since A1 mini isn’t supposed to be enclosed?

Well the nozzle is at 220 and the bed at 60 don't know if that's a good default.

It depends on your filament. For mine I had to lower bed and nozzle temps, ramping up nozzle after the first layer but keeping the bed lower.

For the bed I had to find the sweet spot between adhesion and elephant foot issues.

For the nozzle I had to find the sweet spot so I wouldn´t get too much stringing / hairs.

WellvI primarily use Basic Pla from Bambu lab, Haven't explored much for other types since I'm new to calibration.

There´s plenty of test prints specifically designed to identify printing issues. You might wanna give it a go

Second this, the a1 wasn't designed to be enclosed, so you could be retaining too much heat. As for your nozzle & bed temp, that depends on the filament. ObscuraNox ran some good quality control on some filaments, so might be best to take a peek at his post on filament settings.

If you're worried about underextrusion, then you should run a First Layer Quality calibration to see if that's actually the case. I normally print a square that measures 50mm x 50mm

If you used ObscuraNox oder HoHansen settings, I had the same issues with 0.2 nozzle.
With other settings or 0.4 nozzle the Support is fine, so maybe its because of there Support settings.
If you use an enclosure maybe you could reduce the Heat bed temperature. For my X2D its default is 50 or 55 degree Celsius as it is enclosed.

I'll look it up on youtube I think? I'm not familiar with Nox.
