ORTUR LU2-4 Laser Master 2 Pro S2 Instruction Manual

Your Ortur Laser Master 2 PRO S2 firmware is the operating system that resides inside the motherboard and controls all operations of the machine as well as the interactions between the motherboard and the host computer.
In some circumstances, a firmware update is required to improve the Ortur Laser Master 2 PRO S2 performance or fix discovered issues. In some less common situations, a firmware upgrade might be required to clear issues caused by user error. Please read the instructions below carefully

General Recommendations

When NOT to upgrade or reinstall the firmware

  • Not yet contacted support at https://ortur.tech/support to resolve an issue
  • Ortur Laser Master 2 PRO S2 is working correctly and showing no problems

When TO upgrade the firmware

  • Advised to do so by Ortur or Ortur Customer Support
  • A new version of the firmware is posted at https://ortur.tech/latest-firmware
    advising a firmware update to fix a discovered problem or enhancing Ortur
    Laser Master 2 PRO S2 functionality

Requirements to upgrade the firmware safely

  • This guide covers updating procedure on Microsoft Windows, MacOs and
    Linux. (This procedure was already validated in Windows 11)
  • Direct Connection from the Ortur Laser Master 2 PRO S2 to your computer
    USB port. Note: Some users reporting the use of USB Hubs may cause problems.
  • Have access to software that allows decompressing a .zip file. (Note:
    Windows, MacOs and Linux will natively perform this operation. However 3rd party extractors are also usable)
  • Disable temporally any 3rd party Antivirus Software. Although normally not required it is still a recommendation.

Basic Troubleshooting

There are a few rare circunstances on which applying a new firmware to your Ortur Laser Master 2 PRO S2 might lead to some problems. Below we will list a few of these known issues and how to best address them:

Firmware Write Fail
In some operating systems, specially Windows, security software as Anti-virus or AntiMalware can prevent the complete copy of the BIN firmware file to your
Ortur Laser Master 2 PRO S2 motherboard, causing the machine to become unresponsive. These events are rare but can happen, specially on Pre Windows 8 Operating systems.

Solution:

  1. Please temporarelly disable the security software and attempt firmware upgrade procedures a second time;
  2. Use a different computer. Many users that experience the above issue reported that simply using a different computer allowed for the firmware update process to finalize without problems.
  3. If neither solution above was successful, please get in touch via our Ticketing system at https://ortur.tech/support. Ortur Support team will most likely suggest a remote session to your computer to allow an untouched file transfer to your Ortur Laser Master 2 PRO S2 motherboard.

Wrong Firmware file

Your Ortur Laser Master 2 PRO S2 is expecting a particularly type of file when you try a firmware update. If the motherboard identifies a wrong file format or type it will automatically reject this file and turn off. This will result in the following errors:
Windows: “Error 0x800701B1: A Device which does not exist was Specified” Mac: “The operation can’t be complete because an unexpected error occurred (error 100006)
Linux: “Error While Copying. Error When getting information from file. No such file or directory”
Solution: Please verify that the firmware file is the correct series for your Ortur Laser Master 2 PRO S2. Only 1.8x series firmware files are accepted.
