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:
- Please temporarelly disable the security software and attempt firmware upgrade procedures a second time;
- 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.
- 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.
