⬢Plug the external PSU into the printer and electricity. Ensure the power switch is ON. Press the button on the front to turn the printer on.
See the correct orientation of the connector! The arrow on the flat part of the connector must be facing the power switch. Do not attempt to plug the connector in a different orientation. You can damage the electronics.
There is a sliding lock on the connector. For removal, grab the larger part of the connector and pull it outwards. Don't pull the cable, it won't be able to disconnect that way.
The upgraded SL1S SPEED printer won't work with the older SL1 firmware (1.5.0 and below)! You need to upgrade the firmware to the latest one 1.6.6 or newer.
⬢There are two ways to upgrade the printer’s firmware:
⬢OTA firmware upgrade - (Over The Air) firmware packages are delivered via ethernet or Wi-Fi network. For using this method, please go to OTA firmware upgrading
⬢USB firmware upgrade - firmware packages can be downloaded from the official website. For using this method, please go to USB firmware upgrading
⬢This method requires a network connection. Please, make sure that the printer is connected via Wi-Fi or Ethernet.
Starting with firmware 1.3.0, the printer performs automated checks for newer firmware files online and displays an on-screen message when a new update is found. Firmware 1.4.0 enables a manual firmware check via an on-screen button.
⬢On the touch screen navigate to: Home -> Settings -> Firmware -> Download Now. You will see the new Update is available. Click on it.
⬢On the screen with the new firmware version info and QR code scroll down and click on "Install".
⬢Wait until the whole process is completed. Upgrading the firmware can take a few minutes, depending on the speed of your internet connection.
⬢The printer restarts itself after the installation is complete.
⬢Now, skip to Language and time zone setting
⬢This method requires a FAT32-formatted USB drive with at least 300 MB of free space.
⬢Open a browser on your computer and go to prusa3d.com/drivers
⬢Scroll down and select the ORIGINAL PRUSA SL1 & SL1S SPEED.
⬢You will see the latest firmware version. Click on "Download".
⬢Connect the USB drive to your computer.
⬢Unzip the downloaded firmware package to the USB drive root directory.
⬢Connect the USB drive to the SL1S printer.
⬢On the touch screen navigate to Home -> Settings -> Firmware. The system will recognize the file on the drive, and show the option at the bottom of the menu. Tap the file name to update the firmware.
⬢Click on "Yes" to confirm the upgrading firmware.
⬢Wait until the whole process is completed. Upgrading the firmware can take a few minutes.
⬢The printer restarts itself after the installation is complete.
⬢After the restart, the printer will ask you to set the language and timezone.
⬢Select the language from the list. You can scroll it up and down.
⬢Confirm the selected language by clicking on the "Set" button.
⬢Select the time zone from the list and confirm by clicking on the "Set" button.
After upgrading the printer, some of your projects will not be compatible with SL1S and the printer needs to remove them. You can download them by entering the address from the display into a web browser on your computer.
In order to download your projects, your computer must be connected to the same network as the printer.
⬢Everything downloaded? Click on "Yes". If you click No, the printer will not allow you to continue the upgrade.
⬢The printer detects upgraded components and needs to erase all configuration settings (e.g. UV calibration data, platform calibration data) to complete the upgrade procedure. If you agree to delete them, click "Yes" to continue.
After completing the calibration in the next chapter, the printer will create new configuration settings.
Using the metal resin tank on the SL1S may damage the printer.
⬢Make sure you have prepared the plastic resin tank. Click "Continue" to confirm.
Using the metal resin tank on the SL1S may damage the printer.
⬢Make sure you have prepared the supplied platform. Click on "Continue" to confirm.
⬢Once the hardware upgrade is complete, all settings data (e.g., a print screen calibration) are deleted. Reverse downgrade will only be possible using the UV calibrator. If you agree, click on "Continue".
⬢The print display calibration is automatic on the SL1S SPEED. You don't need the UV calibrator.
⬢For the following steps, please prepare:
⬢"S" sticker (1x)
⬢"SPEED" sticker (1x)
⬢Cleaning pad (1x) you have already used in the third chapter
⬢Clean the area below and next to the PRUSA SL1 logo using the cleaning pad.
⬢Take off the paper layer from the "S" logo sticker. The latter "S" must be on the transparent layer.
⬢Glue the sticker next to the PRUSA SL1 logo. Align the "S" position according to the "SL1".
⬢Carefully peel off the transparent layer and make sure the letter "S" is stick on the metal sheet.
⬢Take off the paper layer from the "SPEED" logo sticker. The "SPEED" letters must be on the transparent layer.
⬢Glue the sticker below the PRUSA SL1 logo. For a better look use the same space between the text as on the logo.
⬢Carefully peel off the transparent layer and make that no letter is missing on the metal sheet.
⬢Good job! You just fully upgraded to the SL1S SPEED printer.
⬢Go to the next chapter: 5. Calibrating the printer
