Prusa Core One

Induction Required

This equipment requires an induction prior to use. For your own safety and to avoid damage to the equipment do not attempt to use it until you have been inducted.

Risks

Crush / Entanglement / Burn Hazard

This equipment is hazardous to the user or those around them, take care during use.

Health and Safety

Induction

Inductions for the 3D printers are now available on the member portal (right-hand PC by the electronics bench). Tap your card/keyfob on the reader, select “Manage machine inductions”, and take the 3D printer quiz. You will then have access on the RFID lockout box, you just need to tap your card/fob and it will switch on.

Print file format: bgcode or gcode - bgcode will load and start printing faster

Please use PrusaSlicer for slicing for the Hackspace 3D printers.

Change the print in settings to Prusa Core One

You may need to update Slicer to get the new print settings this can be found here: Prusa CORE One Support

Printer profile: Prusa CORE One HF0.4 nozzle

General usage and safety rules are the same as the other printers.

However with regards to filament the loading and unloading is slightly different as this has the spool holder and Nextruder - Prusa's next generation extruder with planetary gearbox and LoadCell sensor. Please read below for more information or check the manual.

**DO NOT REMOVE GEARBOX COVER**

DO NOT remove the cover of the gearbox unless you have a gearbox alignment tool that comes with the assembly kit. The gearbox is precisely aligned and calibrated. There is no need to access it and you could misalign the gearbox by removing the cover.

Etiquette

Due to high usage of the 3D printers only ONE should be used by a member at any one time.

Filament

All Hackspace 3D printers use 1.75mm filament. Most filaments such as PLA, PETG, FLEX etc are supported. Do not use filaments that require a nozzle temperature above 285°C such as polycarbonate. Abrasive filaments should not be used on this printer but can be used on tool 1 of the Prusa XL. Examples of abrasive filaments are CF / GF filaments, wood and metal filaments, and glow in the dark filaments. Please also structure your multi-material prints to avoid printing with the brass nozzles on top of an abrasive filament.

Please DO NOT use ABS, ASA, HIPS, PA filaments as we need an advanced filtration system, please let committee know well in advanced if you will need this as a proposal will need to be raised.

Inserting filament

If you are starting with the printer, we recommend choosing PLA for the initial print. This material is easy to work with and does not require complex pre-print preparation.

The printer will ask if the color of the extruded filament is okay. Check if there is filament extruded from the nozzle, and select one of the options:

Please open the top slide vent when using PLA.

Unloading filament

After use: Please completely remove your filaments from all of the lines rather than leaving a clipped amount in. Due to the lines this would be a significant loss of filament and also potential pain of the filament being used by accident by following prints. Select LCD Menu - Filament - Unload Filament

  1. Select LCD Menu - Filament - Unload Filament
  2. The printer will preheat automatically. As soon as it reaches the right temperature, the filament will be unloaded from the extruder in a few seconds.
  3. Once the extruder stops unloading the filament, remove it by hand from the PTFE tube. The filament needs to be wound up on the spool and secured carefully so that it does not tangle up.
  4. Make sure to secure the unloaded filament when you wind it up back onto the spool. If the end of the filament slips out, the spool may become tangled.

Accessories

Similarly to the Prusa XL is that it's very easy to print on different steel sheets. We have two:

Maintenance

Keep heatbed free of debris Wipe the bed with the supplied cleaning wipes soaked in isopropyl alcohol Please do not get IPA on the transparent windows NO ACETONE!!

Troubleshooting

The first port of call if there is an issue is to run a Selftest. This is a set of various tests that serve as a diagnostic tool. This can help detect the most common problems.

The following tasks will be performed:

At one point, the Selftest will ask you to calibrate the filament sensor by inserting a piece of filament through the PTFE tube into the extruder. We suggest preparing an entire spool of PLA filament, so you can start printing once the Selftest finishes.
