Synopsis

Current 3D printers in ACKspace include:

  • Sovol SV07 (documentation WIP)
  • Prusa i3 MK3S (don't mod this one please, if something breaks or fails, please inform @computer1up (Alice), this one is supposed to be the "will usually work" printer)
  • Creality Ender 5, see below.

We have a range of different filaments. At the moment, this includes:

  • 1.75mm PLA (multiple colors)
  • 1.75mm PETG (white, possibly some black as well, not sure)
  • 1.75mm Flex (black, not compatible with Bowden printers)
  • 1.75mm ABS (black)
  • 2.85mm (3mm) filaments of various kinds

Both current printers accept 1.75mm only!

The 3D printer is connected to fuse group B. (is this still correct?)

Status

The Prusa i3 MK3s is currently our main printer. That means: no modifying/hacking/fixing without discussing it with the others. This includes, but is not limited to:

  • Swapping the nozzle
  • Updating/changing/modifying the firmware

Also, if you use any additional bed adhesion stuffs, please remove these after use! The Prusa has a dual-sided smooth PEI sheet which works with most materials and a powdercoated PEI sheet, which has a bit of a texture. Using this isn't recommended with PETG or TPU, only use it for those materials if you know what you're doing (or are willing to order a replacement ;)

The Sovol SV07 is our secondary printer, which is technically preferred to not be modded either, but we're also still working on it (slicer configuration, some small hardware changes potentially).

The Prusa & Sovol both have a direct drive extruder which should work with basically all filament types.

There's an Ender 5 in the stACKspace (storage) which could be used as a platform for mods/experimental things if you'd like.


Bed Levelling

Both the Prusa & Sovol should not need any bed leveling as they have a sensor for that. If bed adhesion is a problem, properly clean the bed with isopropyl alcohol or follow the appropriate troubleshooting steps for that specific printer.

The Ender 5 currently only supports manual bed levelling using the four large levelling wheels underneath the heated bed. Usually this should not have to be adjusted, though sometimes, this may be necessary. Activities that can result in non-level beds:

  • Physically moving the printer
  • Changing the nozzle
  • Manhandling

Slicing

The current recommended slicer is PrusaSlicer for both the Plexi i3 and the Ender 5.

The Ender 5 has a default, native profile in PrusaSlicer. It is highly recommended to use this profile, and not change the settings, unless you are absolutely sure what you're doing! Any PrusaSlicer install should work with the Ender 5, be it on your own machine or the space provided workstation.

The Plexi i3 has optimized profiles installed on the PrusaSlicer install on the space workstation (next to the CNC, HP Omen), which include automagic bed levelling before each print. There are no default profiles for this printer other than that (this printer is an old Prusa i3 clone, and has quite a few mods done over the years, which makes it deviate too much from a 'normal' Prusa i3).

Printing

ENNLDE

The Prusa works with the normal sized SD card. Follow the instruction sheet above the printer for more info.

The Sovol uses Klipper as its firmware and has a webinterface and a touchscreen. You can upload gcode-files to it through said webinterface or with a USB-drive (not tested yet). Check the settings for the IP address if it hasn't been set to a static one.

Slicing

Prusa i3 MK3s: Download and install the PrusaSlicer on your laptop

Open PrusaSlicer

Add printer: Original Prusa i3 MK3S & MK3S+ - go to configuration - configuration-assistant - click next - choose mentioned printer and tick - finish

Open the desired file in PrusaSlicer (.stl of .3mf)

Check printer settings on the right hand side (default is 0.2mm)

Check the filament on the right hand size (has to be the same as the spool on the printer you're going to use)

Take out the SD card from the Prusa printer and insert into your laptop Optionally, use the SD card reader with USB port

Press 'Slice now' on the bottom right side

Click on 'Export to SD card' in the bottom right corner to export the g.code file

Take out the SD card from your laptop (or disconnect the SD card reader)

Sovol SV07: There are some WIP profiles for this printer on the HP Omen PC below the plotter, use them at your own risk since they still need some adjusting. You'll find them labeled as "Alice edition". Better print profiles for this printer are still welcome!


Printing

Put the SD card in the control panel of the Prusa printer

The files on the SD card are being read - pick your file

Printer will do its thing - this can take a while due to warming up

Note: only use the kill button on the control panel as emergency killswitch!

Beide printers werken met een (reguliere maat) SD kaart.

Zet de (oranje) Prusa aan (zie achterkant printer)


Slicen

Download en installeer de PrusaSlicer op je laptop

Open de PrusaSlicer

Printer toevoegen: Original Prusa i3 MK3S & MK3S+ - ga naar configuratie - configuratie-assistent - klik volgende - kies bovengenoemde printer en vink aan - voltooi

Open de gewenste file in PrusaSlicer (.stl of .3mf)

Controleer rechts prnter instellingen (standaard is 0.2mm)

Controleer rechts het filament (moet hetzelfde zijn als de rol op de printer die je gaat gebruiken)

Neem de SD kaart uit de Prusa printer en breng deze in je laptop in Gebruik eventueel de SD kaart lezer met USB poort

Druk rechts onderaan op 'Slice nu'

Klik rechtsonder in de hoek op 'Exporteer naar SD kaart' om het g.code-bestand te exporteren

Haal de SD kaart uit je laptop (of ontkoppel de SD kaart lezer)


Printen

Stop de SD kaart in de bedieningspaneel van de Prusa printer

De files van de SD kaart worden ingeladen - kies jouw bestand

Printer gaat zijn gang - kan wat duren i.v.m. opwarmen

Let op: gebruik de kill knop op bedieningspaneel alleen als noodstop!

Hardware

Prusa i3 MK3s & Sovol SV07: tba. Just look them up on the internet if you really need them. Both printers are still stock.

Ender 5 specs:

  • 0.4mm nozzle
  • Hotend max. temp: 230 degrees C (keep this in mind when printing PETG and ABS! The hotend is PTFE-lined, which means the PTFE tube goes all the way up to the nozzle. PETG can start melting from 230C, which is highly undesirable!)
  • Ender 5 V4.2.7 mainboard with TMC2228 drivers and recent Marlin firmware as of 06-04-2022, firmware has a specific mod to work around a bug with this new mainboard and EMI.
  • Upgaded metal extruder mechanism, since the old one, made from plastic, wore out.
  • Removable PEI springsteel printbed surface, clean with IPA (90% or higher) before/after each print, once a month or so with Acetone (nailpolish remover).

Donations

Please consider donating a small amount when using the 3D printer frequently so we can buy more filament and parts for the printers in order to keep using it. There's a small coin jar next to the printer in which you can put your donation.

The Ender 5 was supplied by Prodigity.

The following people donated for the existence of the original 3D printer in the first place, many thanks to them:
