Mars 3 Assistance

[ Assistance Needed! ]

Sorry for the random request here. I have a Mars 3, its been great. A few months ago when the last firmware update happened I updated my firmware (or so i thought - the instructions aren't really clear). Once i did that I started getting this odd issue.

I would print something, success or fail is irrelevant here. The first print would finish - the head goes in the vat cures a layer pulls up all as expected.... and print done. Cool.

The second print - the head goes about halfway down the z axis and stops. the machine thinks the head is in the vat and starts curing. the head never moves from this point on - never moving up or down - and the UV is curing layer after layer in the vat with no plate.

I contacted support and they sent me a new file to flash (one of the firmware files - the gcode.txt one specifically). I flashed it, didn't do anything as i still had the issue, then removed the txt extension (using the gcode - this is part of my confusion in the firmware process here) and it seemed to work. I got a few months out of the printer in which i didn't need to reset the 0 after every damn print..... but its back now. I updated the firmware last night again to verify but its still happening.

Anyone have this issue? Anyone know how to resolve it? Anyone know the actual files that should be on the thumbdrive to update firmware (gcode.txt or gcode for the last file?). Please advise.

Oof. I wonder if there's a way to flash back to your previous firmware. I'm kind of a Luddite, but this is why I'm terrified to update both the printer and slicer.

Only if they have an archive of old firmware you can download and flash back on.

Definitely let Elegoo know that it didn't fix your issues.

I don't have a solution for you, but there is a reason that Elegoo says on their website to generally avoid firmware updates unless you need to do them.

Thanks for your submission. Please be sure you've looked through the FAQ's before posting. Our FAQ is community-sourced. If you have information to contribute, please reach out with a modmail!

For troubleshooting posts - please include the following critical information:

  1. Printer (model specifically, Mars, Mars Pro, Saturn).

  2. What resin you're using (brand, type, and color).

  3. Slicer, version number of slicer, and print settings.

  4. What you've tried so far.

  5. Include screenshots of the oriented and supported part, as well as photos of the failure, if applicable. Additional images can be uploaded to imgur or similar services and posted as a link in the comments below your original post.

For Unknown File Format issues please see the section titled Why does my printer say "Unknown file format?", found in the Common Problems & Solutions section of the FAQ.

For firmware related issues please see the section titled Updating the Firmware on your Elegoo MSLA Printer, found in the Printer Maintenance & Troubleshooting section of the FAQ. It contains instructions that are more thorough than Elegoo's. Posts regarding firmware will be directed to that link and removed to control repetitive clutter on user feeds, unless your request is well-documented with images/links to images to show that your firmware updating issue is unique. If your post is removed, you will be provided with instructions for how to repost with updated criteria.

If your issue is solved, please update the original post or add a comment about what the solution was. This will help us update and maintain the FAQ, and help people when finding posts via search engines.

Thank you, and happy printing!
