Software issues in 3D printers are common. But because they are easier to diagnose than hardware issues, it is also harder to fix them. One such issue is the Elegoo Mars 2 Pro not recognizing CTB files. A lot of users have reported this issue, yet there is not much information on how to fix it.
The problem mainly occurs because the current firmware of your Mars 2 Pro is not supported by the ChiTuBox 1.9. To resolve this, you can either download ChiTuBox 1.8 again or update the firmware to 4.4.3. Since you’ll ultimately need to update the firmware, it goes without saying that we would advise doing that instead.
This article will discuss why the Elegoo Mars 2 Pro doesn’t recognize CTB files and what can be done to resolve the problem.
Mars 2 Pro
The Mars 2 Pro is a resin 3D printer with a compact footprint (5.08 x 3.15 x 6.3 inches), designed for printing small and more complex items like figurines, jewelry replicas, or other tiny objects and accessories that require a higher level of precision (less prominent layer lines).
A 3.5-inch LCD display, a spring-loaded build platform that has self-leveling, and an integrated air purification system are just a few of the cool features that the Mars 2 Pro has for novices or those searching for a gadget on a budget.
The Mars 2 Pro produces resin models at quite high speeds while sparing only a little amount of precision when it comes to print quality. You simply will not be disappointed with this specific printer if you want to start printing little figurines and display sculptures.
The Mars 2 Pro is a terrific 3D printer that you can use to study and construct your first 3D-printed objects because of its overall robust build quality (lots of metal is involved in its construction), a variety of cool features, and a price that is only around $300.
What are CTB Files?
The CAD program AutoCAD uses the CBT file to connect color and display settings to design items. It provides color-based plot styles or mappings of colors to layers of objects.
Why Won’t Elegoo Mars 2 Pro Recognize CTB Files?
Despite the amazing features of the Mars 2 Pro, many users have reported that their printer is not reading the CTB files. It gives an error “Unknown File Format”. To cut to the chase, this happens because the ChiTuBox 1.9 does not support the previous firmware of the Elegoo Mars 2 Pro. The simple solution is to either downgrade the ChiTuBox to version 1.8 or update the latest 4.4.3 firmware of the Elegoo Mars 2 Pro.
Why is it Important to Update Firmware?
As is the case with all electronic devices, you need to update your 3D printer’s firmware to make sure it continues to work efficiently. Upgrading the firmware is also important because it helps improve functionality and newer firmware contains bug fixes that have been previously reported. Additionally, if you do not update your firmware, you might end up experiencing many issues such as your printer restarting on its own, not extruding, or your printer’s LCD touchscreen not working.
In any case, you should make sure that your printer is running the latest firmware version available for it.
How to Update Mars 2 Pro Firmware?
What You Need
Even though it is a fairly simple process, updating the firmware can sound intimidating for people who are new to 3D printing. But all you really need to update your Elegoo firmware is a USB stick and your printer.
- The official Elegoo Mars website is where you can find the Firmware support files.
- You have two choices after obtaining the firmware files for the printer. Either download the firmware update or download all the files on the USB disc that arrived alongside your 3D printer.
- You need to copy the contents and upload them to the root directory of your USB after downloading and extracting that file.
- After that, execute the files by inserting the USB disc into the printer.
Make sure the firmware downloaded from the website is a more recent version than the one that is presently installed on your printer.
How to Download ChiTuBox 1.8?
Downloading ChiTuBox is a far easier process. Simply follow the instructions below:
- Select Windows, Mac, or Linux in accordance with your operating system’s requirements on the ChiTuBox download page.
- Click the blue download button.
- On the “Sign In” screen, enter your username and password.
- Press the “Sign In” button.
Frequently Asked Questions
What Is the Latest Version of Chitubox?
The latest version of ChiTuBox, version 9.2, was released in March of 2022.
Is Chitubox a Good Slicer?
ChiTuBox shows a glimpse of the printing procedure together with an estimate of the build time and material consumption. Since ChiTuBox’s free edition of the program offers so many features, it is frequently regarded as the best slicer for resin 3D printers.
Is PLA Flammable?
PLA has grown into a standard polymer with numerous applications. However, due to its strong flammability and propensity to spread fire, it is not a perfect substitute for plastics created through petrochemical engineering.
Is ABS Poisonous to Humans?
This product doesn’t contain any dangerous substances when it is processed normally. However, the gases created during the melting process may irritate the eyes, skin, and respiratory system, and if inhaled in excess, they may cause nausea and headaches.
