Electronics and features
Let’s go back a little and take a look under the hood.
The entire underside is removed in its entirety, after which practically everything is exposed.
At the back, we can see the power connection as well as the stepper motor and PCB for the AMS lite.
Also the cable for the heating bed, here in the revised version. Because when the A1 was first released, Bambu Lab had to start a recall campaign because of this cable. Further information can be found on the manufacturer’s blog page.
At the front is a small 100 watt power supply for the hotend and other small electronics.
The belts of the Y-axis are tensioned by a metal spring.
The opposite side is taken up by the mainboard, which is connected to the touchscreen and also provides your SD card reader.
Incidentally, it quickly becomes covered in dust and fingerprints.
On the other hand, it is also used to report problems and suggest solutions without the need for an extra device, which is very practical.
We are also already familiar with the extruder, including the option of replacing the nozzle within a very short time.
It still works wonderfully if you have purchased the corresponding replacement beforehand.
And last but not least, the “brain” of the hotend.
I won’t go into detail about the AMS lite here, as I have already tested the automatic filament change system extensively on the A1 mini.
However, Bambu Lab now offers an extension for self-printing, which enables direct mounting on the printer. As the space saving is just as enormous as the number of downloads, I tested the printer in exactly the same way.
I would also like to mention the option of simply skipping a failed part and continuing to print the other objects.
But I also find it very practical to use up leftover files via the AMS lite by switching directly to the next roll when it is empty.
