Anycubic Photon Printer Owners 造訪社團 » 用戶發文

Ok, I know this has been talked about a lot, but I just want to ask to make sure I don't screw something up. I want to disconnect the fan in the printer to help with the resin smell, as many have done. But I want to make sure I'm unplugging the right one - I have the original Photon, not the S. I read through several posts with folks discussing this, but I'm still a bit unclear on which fan to unplug.

My understanding is that there are two fans - one in the print area right behind the vat, and one on the bottom of the printer. I want to disconnect the one inside the print area behind the vat, correct? And leave the other one alone? Or can I disconnect both?

Thanks in advance!

Ok, so I just submitted a warranty claim to Anycubic. Figured I'd post it here too in case someone has any advice, and just in case one of their reps sees it here and can expedite things:

Summary: Several of the holes drilled into the build plate joint are too large.

When I first received my printer, I noticed that the build plate could "wiggle" horizontally even after tightening it (see the video I uploaded here: https://youtu.be/e5no6izFGps ). It would stay level, but I could rotate it slightly horizontally. It didn't seem to affect the leveling (at first), so I assumed it was normal.

I was experiencing a lot of failed prints, and determined that leveling might be an issue. I followed the steps provided by Anycubic to level the plate, and also followed the advice found on the Photonsters facebook group. I learned from that group that the horizontal "wiggle" was not normal, and I probably had a problem with the joint.

I took the joint apart and cleaned it, and realized that several of the screws were loose. I was able to tighten a couple of them, but at least three proved impossible to tighten. They simply spin in the holes. I tried multiple screws in these holes to make sure it wasn't a problem with the screw, but the result was the same.

Two of the holes on the ball joint itself, and one of the holes around the opening where the ball joint sits, are too large. See the uploaded picture - the bad holes are circled in red. The screws do not fasten, they simply spin.

I tried replacing the screws with ones purchased locally, but that didn't make a difference.

I tried using an epoxy to fix the screws in place, but that didn't make a difference.

The build plate is "wiggling" because there is only one tight screw on the ball joint. The plate also quickly becomes unleveled after printing because of the loose screws.

I'd like the build platform mount and joint replaced, or at least those two parts (circled in blue in the uploaded picture) replaced. Please let me know what it is needed to make that happen.

Thank you.

Anybody know what size the screws are in the print platform joint? I've been having leveling issues, tried troubleshooting, ended up taking the joint apart, and discovered that several of the screws were loose.

Tried to tighten, but a few of them just spin freely. The problem doesn't seem to be the screws themselves, as one screw will work just fine in one hole, but spin freely in another hole. It seems like some of the holes were drilled too big.

So far I've found one bad hole on the little ball joint itself, and one on one of the square brackets.

I'm hoping that a screw with a slightly more aggressive thread will work. Thoughts?

EDIT: Added a photo indicate which holes I've found so far with issues, and just to clarify what i'm talking about. Note that this is not my photo, I got it from the github page. At work right now so I can't take a picture of my own unit.

Hello! Running into an issue with leveling. Using the paper method, following the steps laid on in the videos linked in the FAQ - lowering it carefully all the way down to the glass while loose, applying pressure to both sides, and tightening. Getting it tight, but then when I go to lift the platform back up, I'm noticing the back (toward the Z shaft) is lifting first. As in, for the first .5mm, the back edge is off the glass, and the front is still contacting.

Also, even when tight, the platform will swivel a tiny bit - it doesn't wobble (appears to stay level, aforementioned issue aside) but it does swivel horizontally. Not all the way around, just a bit. Is that normal?

About 75% of my prints are failing to one degree or another, and I suspect this is at least part of the issue. Do I need to disassemble the platform joint? Any other suggestions?

Thanks in advance!
