Ortur Laser Master 2 PRO S2 Firmware
Your Ortur Laser Master 2 PRO S2 rmware 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 rmware update is required to improve the Ortur Laser
Master 2 PRO S2 performance or x discovered issues. In some less common
situations, a rmware upgrade might be required to clear issues caused by user
error. Please read the instructions below carefully.
When NOT to upgrade or reinstall the rmware
• 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 rmware
• Advised to do so by Ortur or Ortur Customer Support
• A new version of the rmware is posted at https://ortur.tech/latest-rmware
advising a rmware update to x a discovered problem or enhancing Ortur
Laser Master 2 PRO S2 functionality
Requirements to upgrade the rmware 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 le. (Note:
Windows, MacOs and Linux will natively perform this operation. However 3rd
party extractors are also usable)

Basic Troubleshooting
Firmware Write Fail
In some operating systems, specially Windows, security software as Anti-virus
or AntiMalware can prevent the complete copy of the BIN rmware le 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 rmware
upgrade procedures a second time;
2. Use a di󰀨erent computer. Many users that experience the above issue reported
that simply using a di󰀨erent computer allowed for the rmware update process
to nalize 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 le transfer to your
Ortur Laser Master 2 PRO S2 motherboard.
Wrong Firmware le
Your Ortur Laser Master 2 PRO S2 is expecting a particularly type of le when you
try a rmware update. If the motherboard identies a wrong le format or type it will
automatically reject this le and turn o󰀨. This will result in the following errors:
Windows: “Error 0x800701B1: A Device which does not exist was Specied”
Mac: “The operation can’t be complete because an unexpected error occurred (error 100006)
Linux: “Error While Copying. Error When getting information from le. No such le or directory”
Solution: Please verify that the rmware le is the correct series for your Ortur
Laser Master 2 PRO S2. Only 1.8x series rmware les are accepted.
There are a few rare circunstances on which applying a new rmware 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:
