Here’s Why Elegoo Mars 2 Pro isn’t Recognizing CTB File

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.

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 Process
