Anycubic Photon Printer Owners 造訪社團 » UV

After a back and forth with tech support they think my issue is a UV lamp malfunction. They want to send me a new lamp, but I’m still within the 15 day replacement survey window.

Should I go with the lamp replacement or just opt to get another machine?

Thanks for the help so far, this group has been super helpful.

I’m making a UV light box lined with foil. Is it best to keep it flat and smooth like a mirror as best as possible or rough it up so it will scatter the light in multi directions?

So what kind of UV resistant clear coat should I be looking for? The lady at the paint store had no idea what I was talking about. So what kind of UV resistant clear coat should I be looking for? The lady at the paint store had no idea what I was talking about. 翻譯年糕

So, typically I'm the one offering solutions, but I've been having a helluva time with my prints lately. I've noticed that the print bed angles up when it is at the bottom (like when I start a print, and it goes to full travel down, it hits the bottom and looks like it pushes the front of the bed up). Anyone have this problem? Nothing else is wrong, no broken LCD, the FEP is likely due for a replacement soon, but nothing major(any tips on the proper app for tuning the FEP?) Since a few prints ago, I've had at least one failure per print (something falling off supports, weird lines at the bottom of the figure, all sorts of stuff). I'm hesitant to take the machine apart, but it feels like I will need to to get to the bottom of this. I used to be a heavy aircraft mechanic, and I just know that if I do take it apart, I'll end up breaking something important getting it all together again.

I don't have a Photon yet, but I'm compiling my list of what to get and curious what y'all recommend. Also is there a cure time or performance difference between LEDs and traditional UV lights? I plan on building my own cure station/bucket.

Got a response

Hi

Got this response from Anycubic regarding the printer reboot error. How do I go about doing #2?

1. Operate "UV Lamp Detection" on the LCD screen to see if the printer sends a restart.

2. If there is no reboot, please help me detect the voltage of the UV lamp port.

Wanted to give everyone a heads up on a Troubleshooting issue with the LCD screen. I had two prints in a row with some "light leakage" where extra material printed on the side of my model. I thought it might be at the start of LCD failure.

So I ran the UV test, and sure enough more of the screen was lighting up than just the test rectangle. The dreaded LCD failure.

I opened up the machine, and instead of replacing the LCD (I had an extra) I just reattached the cable very firmly and ran a test again on a hunch. With the cable re-seated, the LCD worked perfectly! I have a theory that the vibrations of operation can slightly loosen that lcd cable and cause what appears to be LCD failure when in reality the LCD screen is absolutely fine.

So, if you have light leakage, before ordering a new LCD or complaining to Anycubic, I highly advise just going in (watch a Youtube video on how to replace it to see what to do) and making sure the contact is perfect. And to anyone who's scared to open up the machine or whatever, I'm highly non-technical and I will say it was very easy!

I am not trying to slam on Photon at all. Just need clarifications.

I picked up a Photon (Photon 1) a few weeks ago. Started out printing fine. Then it started to shut down mid print. I received a replacement (Photon 2). I still have Photon 1.

I grabbed the power supply from new one and decided to chech power draw. I also just got a new Mars. Checked Mars power draw to compare.

- Photon 2 draws 90 watts during exposure of 1st layer of included test print ? ?

- Photon 1 draws 40 watts ?

- Mars draw on it's test print 1st layer was 40watts.

Searched this forum and found a few refernces that photon max draw was 20 watts (UV array I assume).

So can someone clarify all this?
