Anycubic Photon Printer Owners 造訪社團 » EX

Sorry I tried searching the group so bear with me. Im on my 3rd attempt at printing the default cube that came on the flash drive. My FEP sheet sounds like a snare, i leveled it with paper, my build plate is pretty darn flat id say. And its pulling nothing up from the resin. I guess that means I need to up the initial layer exposure? Is it common for the default file on the drive to need adjustment? The printers going now so I cant check, do I need to reslice the file to up the exposure or can I adjust it on the machine? Thank you!

In need of some urgent help for some reason my printer is not printing as expected and all of my prints are just sticking to the fep film and not to the build platform I know this could be many reasons but what would you try I have tried doing the flint read method and had no luck?

Getting my first ever printer delivered early next week (photon s) and was wandering what is suggested for a tough resin? Couple things printed will be used hopefully

I’m ok with the amount of detail I got and over all I’m happy with the prints but obviously there was an issue with the bottom of the supports. What could I change to prevent this from happening next time?

I recently printed my first model that was split into multiple pieces. Unfortunately some of them don't fit together. The aligning pins are too big, some of the larger portions are rounded. I'm thinking my exposure settings might be off. Thoughts as to whether this might be an under or over exposure?

I'm using Elegoo grey at 8s

Ok...so this was weird and is fixed...but I'm trying to see if I can figure out what the root cause is in case I should be doing something (different, or at all)

Been happily printing along and came to the end of my bottle of resin. I cleaned out the FEP before adding the new resin (different color resin, same brand).

When I started it up, there was a sound ...not grinding exactly...but something was off. I stopped the print, checked to make sure the plate and pins holding the FEP were secure and restarted. Same thing.

I powered the printer off, as someone mentioned this had solved their problem. No luck.

I then pulled out the plate and the FEP again, cleaned everything...and was wondering if I should relevel...(if only to say yes I did when asking for guidance.)

On a lark, I started a print without the FEP or plate in the device.

Sound is gone.

Put the FEP and plate back in. Printing fine now.

Any thoughts on what was going on?

This maybe a stupid question...can you get dodgy bottles of resin?
I have a bottle of grey and black anycubic and a bottle of elegoo clear blue. All recommendations the same 60/8 seconds. This is what I have set out to in the slicer. was using the Anycubic grey and getting great results (pic 1). I then switched to the black Anycubic (same settings) to print a simple base for a model. I've tried upright, 45 degrees, flat, all raised on supports etc but 5 failed prints. Either supports breaking, not sticking to build plate, but mostly resin forming on the FEP which I've had to empty and peel off (pic 2 and 3).
I thought it was the screen so swapped to translucent blue, exactly the same settings, could see the screen working through the resin , and it printed a random print perfectly first go (last pics) ?‍♂️ what's going on with this black resin?

這可能是個愚蠢的問題... 你能得到一瓶樹脂嗎?
我有一瓶灰色和黑色的任何立方體和一瓶elegoo清白藍色. 所有推薦的60/8秒. 這就是我在切片中闡述的. 使用任何立方體灰色, 獲得了很好的結果(圖片1), 然後切換到黑色anycubic (相同的設定)列印一個簡單的模型基礎. 我嘗試了直立, 45度, 平坦, 全都在支撐上, 但5個失敗的指紋. 要麼支援破碎, 而不是堅持構建板塊, 但主要是在我不得不清空和剝離的fep上形成樹脂(圖片2和3).
我以為是螢幕換成半透明藍色, 完全相同的設定, 可以看到螢幕通過樹脂工作, 然後隨機列印了一個完美的列印(最後一張照片) ♂️ 這黑色怎麼了 樹脂?

I know this is going to be hard - but can anyone help me translate my exposure test? I'm using the Siraya FAST Grey resin, so there are no settings for it on the spreadsheet. I'm hoping to add to it, myself, but I don't want to use/spread false information!

I'm leaning towards the 7 or 8, but I also feel like I don't 100% know what I'm looking for.

Thanks!

While my resin printer's are busy printing away at production models I sometimes use the filament printer too rough out designs for future resin print.
Here we have the Gemini Agena docking in 1/48 scale and while Gemini is in resin (and you can see that I'm still working out the shingle pattern) the agena is done in filament because it's less expensive material and in some cases better than the resin.
Now that I'm satisfied with the overall look and scale I will start the model all over to print it in resin with more emphasis on detail.
