Anycubic Photon Printer Owners 造訪社團 » TPU

Hi folks!

I did a little programming over the weekend and now I would like to share the results with you.

What it is about

I have extended the awesome Photon File Validator Tool from Photonsters by the import of Prusa SL1 file format, so that the files generated by PrusaSlicer can be read in directly, without detour via ChituBox or other slicers that support .photon file format. Additionally I have implemented a Print Host, which pretends to be a Prusa SL1 printer to PrusaSlicer, so that the file can be sent to the Photon File Validator with one click, without a roundtrip via file system.

Motivation

The PrusaSlicer is - thanks to its excellent algorithms for auto-alignment and auto-support - very popular among Anycubic Photon users. Unfortunately, the currently common pipeline for print preparation is very cumbersome. Normally it works something like this:

1. Open the model in the MeshMixer or similar, hollow it out, put drainage holes in it and save it again.
2. Open the model in the PrusaSlicer, align it, generate support and save it again.
3. Open the model in ChituBox, adjust print parameters, slice and save.
4. Open model in Photon File Validator, correct errors and save.
5. Print

Even once, it's already time consuming. But if it turns out that there are still unsupported areas (and usually you will find this in the Photon File Validator, that's what the tool is for), you have to start from step 2 again. The whole open/save orgy over dozens of programs is very time consuming and just not fun. I wanted to change that.

Thanks to the new features in PrusaSlicer 2.2+ an external program for scooping out and drilling is no longer necessary, the slicer can do that by itself now. And thanks to the SL1 import into Photon File Validator you can do without proprietary slicers as an intermediate step, so it reduces the pipeline as follows

1. Open the model in PrusaSlicer, prepare it completely and transfer it to the Photon File Validator with a click on "Send to Printer".
2. Correct any errors in the Photon File Validator and save the .photon file.
3. Print

If there are some unsupported areas, simply switch to the PrusaSlicer window, fix the problem and click on "Send" again. This will reduce the time needed significantly.

Warning / Disclaimer

The software is still beta, and may contain smaller (and possibly larger) bugs. I do not take any warranty for functionality, possible damage to the printer etc. USE AT YOUR OWN RISK.

Installation

Currently no installers are provided. You need an installed Java-Runtime in version 11 or later to run the program. Download the JAR file and start the program with java -jar PhotonFileValidator.jar from the command line.

The complete source code (only necessary for developers) can be downloaded from my GitHub repository.

Usage

1. Start Photon File Validator with java -jar PhotonFileValidator.jar from the command line

2. The main window opens.

3. In the main window, click on Settings The setup dialog opens.

4. Make sure that "Print Host Settings / Current State" shows "Print Host is Running". If a problem occurs, change the port and restart the Print Host.

5. Under "Print Host Settings / Output directory", select the directory where the generated .photon files will be saved.

6. Click the button "Show PrusaSlicer settings" and follow the instructions to set up PrusaSlicer.

Basically you only need to adjust two entries in the default Prusa SL1 printer profile:

1. Set gamma correction to zero. This disables the anti-aliasing in the PrusaSlicer, as the anti-aliasing settings cannot be applied at the moment. However, this is not a limitation, as the built-in calculation in the Photon File Validator provides much finer control over the anti-aliasing settings. The import of gamma correction values is the next item on my TODO list.

2 (Optional) In the "Print Host upload" section, set the "Hostname, IP or URL" field to "http://localhost:8080" (or the port number you set). This setting allows you to send the file to Photon File Validator with one click after slicing, without having to save and reopen it.

Hi everyone. I have a question about Photon File Validator. I have been using auto-support in the Prusa Slicer as I was appalled by what was happening in auto-support in Chitubox! On smaller items there was the odd stray single pixel island but nothing to really worry about. But now I am printing something larger and the amount of islands has naturally increased. I add supports in Prusa, slice in Chitubox and send the exported .photon file to the validator. But now there are more islands and the message "blah blah but nothing can be done." appears.

I return to Chitubox and go to the layers delineated in the validator and for the life of me, I cannot see any islands. I go up a layer, and up a layer but still none appear. I'm beginning to doubt my sanity.

So is it OK to just print with these "islands" in the piece for which "nothing could be done" in the validator?

Obviously, once outputted as a .photon for the validator, I can't send it back into the Prusa Slicer...

Thank you *so much* to anyone who can shed some light on this. It's been driving me spare. I have gone through several YouTube videos but my work is somewhat different from the models used to teach with.

Are there any soft pliable resins out there such as TPU in the FDM world ? I need to make a drop resistant case for something a bit bigger than a cell phone.

How squishy is flexible resin? Like tpu squishy or

I want to print phone cases etc...

柔軟樹脂有多麼的? 喜歡tpu squishy或

我想列印電話箱等等...

Hi folks, can I ask a favour please? I've mixed up my original Photon power brick with a bunch of others that look quite similar but have different amp outputs (for LED studio lights). Could someone please post a pic of the power brick from original photon, showing the input-output voltage/amps please? The back of the photon itself doesn't seem to say anything other than 240/120V at.

The one I *think* is the anycubic one is showing 12v 6A output. Does that look ok? I also have a 12v 4A one. Both are unbranded and bot fit the photon power port.

Thanks in advance!

Hi guys. I am a Photon S owner, but I believe this can be answered also by normal Photon owners.

I am currently testing different options, to see what allows me the best setup for what I want. I am testing most of all so there is no need to advise me for one in particular.

I would like to know something about the official Anycubic slicer. I am using the latest version which they say can output files in .photons, which I'm using because I didn't update my Photon S since I got it in october and it wasn't locked to .pws.

How do I tell it to save in .photons (or .photon for Photon owners) please ? Here I have this option, and during slicing I have progress bars for the different formats, BUT it only saves as .pws in reality. I don't have a .photon or a .photons file in my folders when the progress ends.

Thanks for the help.

Well I finally have a chance to set up and try and print for the first time. And nothing.
No matter which slicer, or file format I output nothing prints. . photon files say unknown format, as do .pws. .photons says done immediately and then raised bed to crash into the top of z axis.
Is this a firmware issue?

Next question... I've downloaded and followed the instructions for firmware update. And nothing. It ignores the files on boot, and if I select them once loaded just says unknown file type. Any advice?
Thanks

Hey! I see this come up a bunch here and I wanted to share my experience.

I spent several years developing LED strip lighting products.

Standard white LEDs use 480nm Blue Diodes and Phosphors, which take blue light and convert it to yellow and green to make White light.

480mm is the standard blue diode, royal blue/deep blue leds are available but their output is much dimmer so they are not used to make white LEDs (less efficient) or RGB LEDs (difficult to match diode brightness).

All diodes are slightly different, in terms of wavelength, output, temperature, voltage, etc.

Despite what the Google Images searches will show, 480nm LEDs DO have output all the way down to UV (although not much). The curve is more like an asymptote.

You don't need a Spectral Irradiance Meter to test this just turn on any RGB strip to blue and you will see fluorescence.

Do your White Task/Desk/Work LEDs have enough UV to cure resin? IMO, maybe, depends on the resin sensitivity at higher wavelengths and the intensity of the lights.

Is it better than fluorescent or sunlight? Absolutely.
Just something to keep in mind.

(Edit for clarity maybe)

So still having some problems getting a print. I basically get a disc of resin. Based on the suggestions I have gotten here, I have confirmed levelling and balancing (using the 3DPrintFarm video recommended) and checked that the FEP is tuned to 315.

Still no joy. What's next on this troubleshooting path? (I'm convinced the problem is PEBCAK) I know there's settings I can tweak within the slicer software...but any tweaks I make would be shooting blindly...is there a good resource to read up on what each setting does and how adjusting affects output?
