Currenty there are following 3D-printers available to use:
Join the #3dprinting channel on Slack and ask before doing any experiments!
Monitor first layer like a hawk! Bad things can happen otherwise!
- Check in on your print periodically. Voron has a camera, Prusa camera is currently to-do.
- See troubleshooting if your print is peeling off.
- Check what filament is loaded before starting your print. If you want to use something else, see instructions for how to change filament.
Nozzle: 0.4mm
Material: PLA / PETG / ???
WebUI: prusa.k-space.ee
Inventory: k6.ee/21Fj
The MK3S+ is currently running Klipper firmware instead of the stock Marlin firmware - as such, a couple slicer settings need to be changed before printing. This assumes that you're using the default Prusa MK3S+ profile.
- Under General in Printer Settings, change G-code flavor to Klipper.
- Under Custom G-code, replace the contents of Start G-code with:
M104 S0 ; Stops PS/SS from sending temp waits separately
M140 S0
PRINT_START BED=[first_layer_bed_temperature] EXTRUDER=[first_layer_temperature[initial_extruder]]
- and replace End G-code with:
PRINT_END
Make sure to save your changes as a new profile!
- Set up PrusaSlicer as detailed above.
- Load up 3D model. (STL, 3MF, etc..)
- Slice the model, note how much material is used- (see "Paying for print" below)
- Upload .gcode file to WebUI and print.
Voron V2.4 Stealthburner(?)
Bed 300x300mm
Nozzle size: 0.4mm
Material: (Only!) PLA
WebUI: voron.k-space.ee
Inventory: k6.ee/21gC
- Get Prusa slicer
apt install prusa-slicer
or https://help.prusa3d.com/downloads (alternative is SuperSlicer)
- Select Voron V2 Afterburner with 0.4mm nozzle (Configuration wizard -- under Other vendor)
- Set the Filament type to PLA
- get STL file, open with PursaSlicer
- Select correct printer, layer height and Filament
- Slice and send to printer
Remarks:
- Layer height: 0.2 should be fine for most applications.
- 215 may not be enough for first layer. If the print starts with dry chunks, 220-225 'fixes' the issue. You can change the temperature in PrusaSlicer under Filament Settings.
- It might be a good idea to start preheating to save time.
Setup:
voron.k-space.ee does not work, it's behind Authelia. You must be in VPN to use the local IP.
After slicing:
- Clean magnetic printing pad (dark gold, thin removable plate) with non-sharp tools, clean the surface (wet towel works, in extreme case use window cleaning liquid).
- Apply layer of glue slime (bottle around 3d printer) and/or glue stick on printing area. Smear it with wet paper towel evenly across the surface. One layer might work for 1-5 printing. YMMV.
- Ensure that glue layer is dry.
- Connect to https://voron.k-space.ee
- Filename must begin with your name
- Upload your .gcode file under Jobs tab. Start print.
- Observe print progress closely (if the glue does not work properly the object may peel off from pad and make a big mess).
- When ready, you may remove printed object immediately -- remove magnetic pad from printer and twist it in two different directions to extract object from pad.
- Remove residues from printer and pad.
Heating the pad makes cleaning easier. Either WebUI: Thermals → Presets → Clean heater bed or from printer: Click wheel → Temperature → Bed
Printers have cameras. Use them (to monitor)!
- Heat up extruder to required temperature for filament
- Open filament latch (black thing on left top of toolhead)
- Pull out PTFE tube and filament, take spool off the holder (once you've pulled the filament out, make sure to either run the end through one of the holes on the side of the spool or tape it so it doesn't get tangled)
- Take new filament, cut off the tip with pliers at a 45° angle
- Put spool on the holder and put PTFE tube in toolhead, run filament through PTFE tube until filament starts coming out of the nozzle (make sure extruder is still hot!)
- Close filament latch
PLA usually costs ~20€/kg
K-Space accepts donations for used filament.

TL;DR: Do the first layer calibration.
(TODO: check for printer-specific values. Voron: Z-0,525 ?? )
Example calibration values:
Clean the surface. Try fiddling with the Z-height (menu->calibration->z-height cal).

- 600 (the two leftmost lines)

Follow these tips in order.
- Take off magnetic sheet and wash it with dish soap, water and paper towels. Make sure to scrub thoroughly!
- If that's not enough, use glue.
