Overview

The 3D printer is driven using Octoprint. Connect to that by going to http://alex-ender3.local or http://10.0.50.3, rather then the IP address listed on the sticker on it.

The config for the Marlin firmware on it is stored in https://github.com/DoESLiverpool/marlinconfigs/

Let's get started...

Safety precautions

This is a consumer-oriented machine, so it's very safe to use. Just be careful of the "hot end" that does the printing, it gets... hot.

Hints & tips

At present the bed level is a touch too close to the nozzle. @amcewen has found that setting the first layer thickness to 0.3mm in Cura is a good workaround.

Printing...

• PETG Start with the default PETG settings in Cura, but adjust the extruder temperature to 246°C and set the speed to 30mm/s. Use blue painter's tape on the bed so that it doesn't come adrift while printing.
