The Anycubic Mega X is new enough that the machine doesn’t appear in Cura’s “Add a printer” interface. This short guide will show you how to add the Anycubic Mega X to Cura and set up the correct Anycubic Mega X Cura profile.

Anycubic Mega X Review (2023)
A budget 3D printer with a MASSIVE build volume.

1 – Add a placeholder printer

Open Cura and navigate to Preferences > Printers > Add and select Add a non-networked printer.

Then, select Anycubic > Anycubic i3 Mega. We’ll use this as the base for the Anycubic Mega X since it’s similar and then modify the profile from there.

Finally, change the printer name from “Anycubic i3 Mega” to “Anycubic Mega X” and click Add.

🛈 If you see “Anycubic Mega X” as a selectable option, it means Cura has been updated to include the Mega X natively. In this case, select it instead and proceed to the next step to double-check that the settings are correct.

2 – Edit the placeholder machine settings

In the preferences window, select Anycubic Mega X under Local printers and then click the Machine Settings button.

This will open the Machine Settings panel that we can customize for the Mega X.

3 – Set the Anycubic Mega X Cura Machine Settings

Make sure the following Anycubic Mega X Cura settings are selected:

Mega X Printer Settings

Printer Settings

Y (Depth)300mm
Z (Height)305mm

G28 X0 ;Y0 ;move X/Y to min endstops, so the head is out of the way
G1 Y180 F2000
M84 ;steppers off
M300 P300 S4000

When you’re finished, click Close to save.

4 – Optional: Change recommended print settings

Now that the machine itself is configured, you can optionally change a few print profile settings for the Mega X. The default print settings inherited from the i3 Mega should work great for the Mega X, except that I recommend updating a few values (below).

Download the Mega X Cura profile

You can find importable Cura profiles for PLA and TPU on the USB drive that came with your printer, or mirrored on our GitHub repo. Download those profiles and import them in Preferences > Profiles.

Or, manual setup

Navigate to Preferences > Profiles > Normal, click Duplicate, and give it a name such as “Mega X Profile” or “Mega X Normal Profile”. I generally use a single profile and update quality from there, but that’s up to you.

Close the settings panel. In the normal “Print settings” Cura panel, change the following settings:

Print Settings
Infill Density20%
Infill PatternGrid
Print Speed50mm/s
Outer Wall Speed30mm/s
Travel Speed120mm/s
Z Hop When RetractedYes (checked)

When you’re done, reopen the profile in Preferences > Profiles and click Update profile with current settings/overrides.
