My first print!
4th attempt
Setting
Layer 0.05
NET 15
OT 1.5
BET 120
Bottom Layers 10

Pretty stoked to finally turn something out! It’s been a few days of failure. Not that I’m saying this was a huge success but it’s a start! Came out very brittle and in post processing I snapped the spell effect from his hand. And some structure that will be tough to get at. I’ll have to play around and research on exposures and such to try to find the sweet spot.

Any tips and tricks would be helpful and appreciated.

Flame on! ?

Short Version: Please help me with a memory m_11800 error. If you've overcome this error please tell me how you were able to fix it. I'm also open to suggestions for other things to try. Finally what firmware should I use if I update it? Anycubic.com has two listed V5.0.2 and V4.2.19, which firmware should I use? My photon currently has V4.2.12
Long Version: Hello there folks, I started with the anycubic photon this wednesday and definitely had a couple of days of that sweet sweet honeymoon before slamming into problems. Namely I had a print stop mid print with an error code (because I'm foolish I didn't record what it was but I have a sneaking suspicion) and since then I can't get anything to work. I've had over prints not sticking to the plate, many many memory errors and finally I've contacted anycubic support, but I would like your opinions in the meantime as I await a response from them.

Fixes and troubleshooting I've tried:
I did what I thought was best so I opened up the photon docs on the photonsters github and got to troubleshooting.:

First thing's first, I ditched the stock usb to use a much better one that I had on hand, 8gb, fat32 etc. However this still resulted in a failed print with a memory error.

Next, I removed the usb stick and did a power cycle for the printer. This allowed me to do a full resinless print (no resin in the vat) so I could double check that the usb could be read. It seemed to work fairly well, the photon went through the entire print without a memory error. With resin however my next print did not stick to the plate at all, I checked my FEP tension, found it was at 280 Hz according to an audio analyzer, releveled the build plate and checked everything again without resin. It seemed much better, I tightened the FEP to 300 Hz just in case and tried again. After which, with resin in the vat, the next couple prints failed with a memory error m_11800, however the failed prints are sticking to the plate and even filtering the vat and checking the FEP all is clear in the vat. However the memory error is still very annoying. I figured it could be PSU related because the first time and last time I had a memory issue while printing if I moved the PSU at all it would disconnect the mains from the adapter via the adapter's plugin. So I zip-tied the two together, removed my UV lamp from the powerbar (when I turn it on it messes with my regular lamp so I know it doesn't play nice with the other devices plugged in). I also decided to try with the usb stick plugged directly into the motherboard to minimize any potential issues. Memory error. M_11800 again. So I started a support ticket and here I am now.

What should I try next? 翻譯年糕

How are experiences using EPAX NON-FEP on Photon?

Anybody here installed it? How are printing results? How are experiences using EPAX NON-FEP on Photon?

I've run an exposure test but I'm having trouble deciding which column looks the best. Perhaps the kind folks here could be of assistance?
I'm going to be printing 28mm miniatures for the most part if that is relevant.

Never mind the white fluff, that just seems to be from the paper towel.

The first guy had his feets melted to the raft, the second one didn't get a raft (but printed perfectly) i got somes accessoires where 5 mm down disapeard in bed, and others perfectly fine. All that on the same print, and with no logic placement (the one without raft was at centre, the one without feet in a corner and the 3 backpacks was separated) so i have to ask, wth is going on here ?

Getting down to details.

Hi all,
I am trying to print a flat object using Photon and I am keep getting visible horizontal lines on the surface of the print (as shown in the photo) which I think it is from the surface lines of the building plate. Would there be a solution to remove these lines?

Another question: I leveled the bed to best of my knowledge. After I was done leveling with paper I clicked back and clicked z:offset and clicked enter to save.

When I hit home ; it still hovers slightly above plate. That’s supposed to be like that right? The Z offset is just adjusting difference in height?

I constantly am amazed at how well these printers do...the "hydraulic cylinders" in the photo are .010" in diameter on the small end! And the fit of the parts is awesome. I figured .005" clearance and the parts fit beautifully

So...is this normal? (Doesn't seem like it should do that. I don't recall it doing this before...)
Or could this be what is making some of my prints turn out funky?
And.... (If need be) how to fix it?
I've tightened the screws I can see. The top one for the leveling, and the four at the base. (though I dont think they matter to this particular issue?)
