[Resolved] Anycubic Photon Mono X 6K isn’t Reading the File to Print

A user shared on the forum that the Anycubic Photon Mono X 6K cannot read files to print. There are many reasons for this to happen, the common ones are file format mismatch, USB drive not saving files, etc. Here we share three effective solutions to help Anycubic Photon Mono X 6K users solve the problem that the printer cannot read files.


Solution 1: Check the File Format

The most important step in troubleshooting a printer that cannot read a file is to check the file format. Especially when you can print the sample files and test files provide by Anycubic, the most likely reason is that your custom files use a format that the printer cannot read, and the machine will display "Failed to open file!".

The file formats supported by Anycubic Photon Mono X 6K are .photon and .pwmb format. Use ChituBox and other slicing software, please save the file as .photon format. Use more recommended official slicing software, please save the file in .pwmb format for Anycubic Photon Mono X 6K. The official slicing software Anycubic Photon Workshop is completely free, supports all models and parameters of Anycubic resin printer, and supports customizing and optimizing printing parameters.


Solution 2: Check the USB Drive

For Anycubic Photon Mono X 6K not reading files, USB drive troubleshooting can be used as a step. As USB drive problems can also affect file transfers, or file accessibility. The following are the specific steps.

  • Always eject USBdrive from windows to avoid corrupting the files
  • The print appears empty when displayed, save it again from Photon Workshop and try to open it on the printer.
  • Check the USB drive connectionto make sure it is securely connected to Anycubic Photon Mono X 6K printer's port.
  • If necessary, you can try to format the USB drive. Please format the USB drive with FAT32 and 4096 bytes, and the memory must be within 16G.The new file must be saved on a USB that has been fat32 formatted.


Solution 3: Update the Printer and Software

There may be a situation where the new version of the slicing software is not compatible with the old version of the printer. You can download the latest firmware and refer to the zip file on Anycubic official website to update the printer. Note: Please read the information about the firmware carefully before upgrading the firmware, and make sure that your machine is suitable for upgrading.

In addition, it is highly recommended for Anycubic Photon Series users to update the latest Workshop 3.0. With a new UI interface and more powerful functions, you can select all Anycubic resin printers, change settings and save the slice file correctly.
