All members must use Chitubox slicing software for our resin printers. This is important for ensuring the community has access to printers that are easy to use, ensuring machine longevity, and producing high-quality prints. Printing settings may be adjusted as needed, but machine settings may NOT be edited. Chitu Systems designs and manufactures the controller boards for our Elegoo 3D printers, and provide optimized printing profiles within the slicer. Per-resin exposure settings should be tuned as-needed.

Chitubox is compatible with Windows, Mac, and Linux.

  - The printer profile will now be imported into your workspace, as well as some default resin presets


==== Troubleshooting ====
  * **My files are not showing up on the printer:** \\ Make sure your flash drive is fully plugged in.
  * **My files still are not showing up on the printer** \\ Check to see that your flash drive is formatted as FAT32/exFAT. NTFS is not supported.
  * **My files still are not showing up on the printer** \\ Make sure your export file format is __.cbddlp__
  * **My prints are detaching from the bed:** \\ Level the bed prior to starting your print
  * **My prints are still detaching from the bed:** \\ Make sure the vat is clean and there are no debris stuck to the release film

===== Material Profiles =====
When using a new resin, it is recommended to calibrate the exposure time. Exposure times vary per resin and per resin color.

To find recommended exposure times, find your printer and resin combination in the spreadsheet below.
