PrusaSlicer Software Installation and Configuration ( Windows, Mac, Linux )

• Make sure to install the PrusaSlicer software FIRST from the following link:

  • https://www.prusa3d.com/page/prusaslicer_424/

• Configure ULIO 3D STEAM™ in PrusaSlicer

  • Download the PrusaSlicer_config_bundle file

    • This file is also available on the Micro SD card (included in the kit)

  • Import the configuration file into Prusa Slicer (watch the video on the left)

  • You are now ready to use PrusaSlicer software with your ULIO 3D STEAM™ printer

Adjusting the distance between the nozzle and the print bed

This step is VERY IMPORTANT because it can make or break your print!

Manual adjustment of the distance between the nozzle and the print bed:

• Make sure to clean the nozzle tip of any plastic residue.

• Manually position the hotend nozzle in the center of the print bed. If you have a 0.2 mm adjustment gauge, you can install it in the center of the print bed

• Screw the yellow adjustment bolt all the way in (it's at the top left)

• Manually turn the Z-axis motor coupling clockwise to raise the print bed until the nozzle contacts the 0.2 mm gauge.

• While keeping the nozzle position in contact with the 0.2 mm gauge, unscrew the yellow adjustment bolt until it closes the Z switch contact (a red light will illuminate)

• Once the manual adjustment is complete, check if the distance between the hot nozzle and the print bed is correct.

  • Click the yellow button on the LCD display.

  1. In the menu, select the 'Motion' option.

  2. Click the yellow button again.

  3. Click on the 'Home Z' option.

  4. The Z-axis zeroing begins automatically.

Very important:

• Cut the end of the filament at a 45 degree angle

  • If you are having trouble getting the filament through the gold fitting on the Bowden tube, try cutting the filament 45 degrees in the other direction and then reinserting it

• Straighten the tip of the filament about 3 inches

• Pinch the extruder handle

• Insert 2 to 3 inches of filament into the white Bowden tube

• Click Load filament from the LCD controller (watch the first video on the left)

  • The nozzle should start heating up for PLA

IMPORTANT NOTICE

• Turn off the heater (Cooldown) if you are not going to use the printer immediately (watch the second video on the left)

Repeat at the beginning of each print

• Lift the flexible print bed from the printer

• Clean the printing surface with isopropyl alcohol ( 70% ) after every 5 prints

• Reinstall the flex plate onto the print bed (as shown in the left image)

Repeat at the beginning of each print

Slicing with Kiri Moto ( Chromebook )

• Kiri Moto is a free online software.

• Select the ULIO 3D Steam printer from the printer list instead of the ULIO 3D BRIX.

  • Do not change the default print settings.

• Avoid printing parts with a wall thickness less than 0.8 mm

Slicing with Prusa slicer

• Start the PrusaSlicer software

• If you haven't already, make sure to configure ULIO 3D STEAM in PrusaSlicer (see PrusaSlicer Software Installation and Configuration at the top of the page)

  • DO NOT CHANGE the default print settings of the ULIO 3D STEAM™

• In PrusaSlicer, select ULIO 3D STEAM™ as your 3D printer

• Import the STL file dog_full_by_bs3.3mf from the Micro SD card provided in the kit

  • You can also visit Thingiverse to download many other STL files

    • If required, adjust the scale and orientation of the 3D model

    • Add support if needed

    • Do not reduce the scale of the 3D model too much.

      • Avoid printing parts with a wall thickness less than 0.8 mm

• Slice the STL model and export the Gcode file to your micro SD card (watch the video on the left)

Repeat at the beginning of each print

• Insert the micro SD card into the microcontroller

• Click the LCD button

• Scroll down the menu

• Select Print from media

• Select your Gcode file by name

• Click Print again to start printing (watch the video on the left)

Repeat at the beginning of each print

After manually adjusting the distance between the nozzle and the print bed, you will now make a much more precise adjustment with the Babystep Z function

• While the printer is applying its FIRST layer, adjust the distance between the nozzle and the print bed with Babystep Z (watch the video on the left)

• You have to wait for the printer to deposit its first layer of PLA

• Click Tune and select Babystep Z

  • Choose a positive value to lower the print bed (in 0.25 mm increments)

  • Choose a negative value to raise the print bed (in 0.25 mm increments)

  • Continue adjusting the Babystep Z until your first diaper looks like this

Once the print is finished, you can leave the filament in the printer, otherwise you can remove it

• To unload the filament, select unload filament (watch the first video on the left)

IMPORTANT NOTICE

• Turn off the heater (Cooldown) if you are not going to use the printer immediately (watch the second video on the left)
