anycubic-photon-docs VS PhotonFileValidator

Here is a selection of gcodes including those covering movements.

For interest Photonsters have most if not all firmware versions on Github.

I found this code on github from another thread for resetting to factory settings, thats my best guess to be the issue considering I was able to press home and change the z=0 just before printing for the first time, but im also new to printing in general and wasn't sure if this code would work for the Mono.

There's no post, but its mentioned in the Photonsters Github, specifically this Google Docs spreadsheet which has a youtube video link with a brief explanation. These docs are mostly for the original Photon, but most of it applies to other machines too.

Problem with these SLA printers is that they're not that well documented, for the original photon it's known that the steps/mm are changed with an M8010 command, but i'm not sure if it's the same for the S. You can take a look at the default config gcode for the OG photon to see how it's configured. The figure of S0.000625 there indicates a leadscrew pitch of 2mm for the OG photon, so i guess they changed it on the S. This would imply that making a gcode file containing:

This happens to me when my model has some island between the support and the model. Usually I use a program, Photon File Validator, to verify my model after the slicing processing. The program is free. https://github.com/Photonsters/PhotonFileValidator

I will definitely second Chitubox as well, just as many folks use and recommend Lychee as Chitubox, so try both and pick your preference. Chitubox does now have island detection, though I would recommend Photon File Validator for more complex prints where you really want to be sure you've caught everything. It detects and indexes islands quite nicely and has a function to 'fix' (read: fill) single pixel gaps causing islands, though those aren't a big deal anyhow. Only downside is having to export as a .cbddlp from Chitubox, import into the validator, then reimport the fixed file into Chitubox for any additional manual supports.

You'll have to forgive me, but I need a little more detail to help. Let's take the Photon File Validator.

To double check for islands you can use Chitubox v1.8.0 and above. Or download Photon File Validator, Whilst chutibox can repair files, it is not particularly good at it, but it will highlight problem areas that you might be able to fix with additional supports. PFV on the other hand cannot add supports, but allows you to edit the pixels on each layer.

Check your sliced file in something like UVTools or the photon file validator to make sure it isn't a slicing/file transfer error (unlikely but worth a check).

.photon lets you use the Photon File Validator, but for .pws you can still use alternatives like UVTools. UVTools can also be used for converting sliced files between formats.

Double check the sliced file to make sure it isn't a slicing issue. A quick check in something like PFV or UVTools will tell you.

I'm assuming an original Photon, and you've had it a while. If the sliced file looks ok when scanning through the layers (Either in the slicer or PFV/UVTools), its either printer settings or a hardware issue.

I orientate pieces manually, just eyeballing to try and minimise areas that'll need excessive supports. It always seems to work out for me. I still run my sliced files through PFV or UVTools to make sure it hasn't missed anything major, and its never let me down. When removing the supports combined with warming the part, the supports come off beautifully and leave almost no trace, its like magic! But I think thats less PrusaSlicer, and just good practice in general.
