Howto: Bambu A1 Mini

Introduction

This is intended to be an easy to follow guide to help people with Bambu A1 Mini basics.

Switch it On

The Bambu A1 Mini is not an induction machine. The card reader on the wall behind it is from the deprecated Ultimaker printer.

The Bambu A1 Mini on switch is on the back under the print bed.

Check Print Bed

Please check the print bed is clean before you start. Dust, grease and previous users plastic detritus will all work against you trying t get a good print.

(TBD -- Where to find bed cleaning materials)

The print bead needs to be clean for maximum chance of a good print.

3D Print Area Tools

There are various tools available in the 3D print area for snipping filament, helping remove prints from the bed and maintaining the printers. Please use the correct tool for the job and if tools are missing let the 3D team know.

Load Filament

Place your filament on the printer spindle or the filament holder beside it. Take care the filament can move freely and is snag free. The filament should be fed gently into the guide tube until reaches the print head.

Inserting the filament.

Filament settings, loading and unloading are controlled from the control panel "filament" menu.

Control panel filament settings and actions.

Different filaments need different temperatures and can be printed successfully at different speeds. The filament settings on the printer must match the filament you are using.

Change the filament settings.

Loading filament into the print head is controlled from the printer control panel. Sometimes the mechanism doesn't grip the filament first time. This is fixed by gently pushing the filament into the printer while retry loading. This may take several attempts.

You won't want filament left in the head by the previous user contaminating your print. The printer runs a purge at the start of a print. When the old to new filament colour changes the transition from old colour to new colour can be seen in the purge. Manual "retry" loading new colour filament until it is clear of the old colour, anecdotally, extrudes more filament than is extruded on the start of print purge. Especially when changing plastics you may want to "make sure" by performing a manual purge.

Start loading filament into the print head.

Filament loading can be monitored by watching the filament purged from the head.

Check filament is correctly loaded.

Removing previous users filament.

Find Access Code

Access code can be found under settings.

Access code can be found under Settings; Subpage 3 of 4; LAN Only Mode

The access code page. This image shows an old access code which does not work anymore.

Filament Stuck

TBD -- Needs photos of relevant screens

When the printer is printing filament can pop off the spool and get caught around the spindle. If this happens the printer will stop waiting for user input. If you are midway through a print the screen will likely be black as well. Just tap the screen to wake it up. There should be a telling you to check your filament and press continue when good to go.

Finished Printing

At the end of a print the print head moves to a "safe" position

Unloading Filament

Start filament unloading by selecting the filament option in the control panel.

Select "unload" option to detach filament from print head.

Printer is ready for manual filament removal.

Gently remove the filament from the filament guide tube.
