Anycubic Kobra 3 Combo 3D Printer

A four-spool printer: the ACE Pro swaps filament during the print, so one part can be multi-coloured or have soluble supports. The 250 × 250 × 260 mm volume fits an electronics enclosure, a bracket or a spare part. For bigger parts the Kobra 3 Max stands next to it.

Materials

PETG is always in stock and free to use. You can bring your own filament. Put an opened spool straight into the ACE Pro: it doubles as a dryer, for your filament too. Do not load abrasive filaments with carbon or glass fibre; they wear out the standard nozzle.

How to use

1. Slice your STL or 3MF in Anycubic Slicer Next. It is installed on the Lenovo laptop next to the printers, and you can install it on your own computer.
2. Copy the file to a USB stick, they lie next to the printers, and plug it into the printer. Printing over the network is not set up yet.
3. Check that the right filament is loaded and start the file from the printer's screen.
4. Watch the first layer. If it lifts, raise the bed temperature. If that does not help, there is a glue stick nearby; after such a print, clean the plate yourself.
5. You may leave the printer running, but it has no sensor for a part that came loose, so look in from time to time.
6. When the print is done, take the magnetic plate off, let it cool a little and flex the part off. Do not pry parts off on the bed.

Take care

• The nozzle runs at up to 300 °C and the bed at up to 110 °C. Keep your hands out while it prints.
• Clear away filament scraps and supports and put the plate back.

Access

The printer is in the hackspace room, so a plan with hackspace access is required. No induction is needed.
