Anycubic Photon Printer Owners 造訪社團 » 3M

Hi, I've tried to print this d20 dice and i had a issue with the supports, they merged together in a full resin block as you can see in the photo.
What could the cause be?
Printed on a photon S with anycubic red at 0.03mm resolution with this settings:
4sec base exp
80 sec base exp
8 base layer

Didnt print with photon for alomost 3months, decided to give it a go again ..... still very happy with the outcome. Long live Photon. lol. https://www.thingiverse.com/thing:3945612 https://www.thingiverse.com/thing:3947761 翻譯年糕

Hi - S’me again, asking more questions as I learn. I have designed this in Fusion360( can’t claim credit for the idea but can for the design) - this is so basic it’s unreal- one flat base, two hollowed cylinders and some embossed lettering. However, as you can see the base has not printed correctly- it sort of tapers away towards the ‘front’. I print the correct way up - ie the base first and then the cylinders . This is the third time I have tried this print and I am wondering what I am doing wrong? Is
the fact that the base is so large a problem -
Should I try printing it upside down ie cylinders first, finishing with the base? Should I try supports? Settings for this were Bottom Exp 60, Bottom
Layer count 7 , exposure 10, layer height 0.03mm.

Does anyone know what are optimal lift and retraction speed and distance? Has anyone played with those settings?

I've explored and measured exposure time (with photo cell and oscilloscope), mechanical cycle time, speeds and feeds. But I have no clue what are "the best" settings. As one could go lift distance of 3mm and speed of 300mm/min for both lift and retraction and get mechanical cycle time in order of 2 sec (1.2s calculated). I bet print quality would suffer. But you could cut printing times a great deal ?

Update: my recent test shows, with aggressive settings mechanical cycle is just 1.76 seconds, meaning that most of the time you are exposing the resins.

Hello!
I've got three problems with my photon printer (I must add, it's an older version, with blue glasses). Slicer: chiTu box:
Dramatically long exposure times needed (I've tried 0,05mm layers) - for Monocure Rapid clear the results from the exposure tests were 50-60s, in comparison to 11-12s that is recommended by its users. That causes that most prints require over a day to print out, which is ridiculous ;/ Z-wobble (?) and squeezing the bottom parts of prints - the cube is like "cut" in the bottom, also when I add 5mm offset from buildplate for supports - its like 2-3mm high. Also prints has small "scars" on them in z-axis. Bad surfaces over the supports - especially with flat, big surfaces, it seems like the resin has trapped there on the top of the print, and hardened there during the whole printing process. Obviously it looks better for prints tilted by 45 degrees, but not perfectly at all.
The things I've already done: plastic cover for all the windows in photon plenty of re-levelling bed, trying to print with tight fit of piece of paper, and quite a loose fit checking it with dry runs - piece of paper moved easier after first few layers re-tightened z-rod cleaned the brass nut on the z-rod and changed the grease on the z-rod changed lifting distance to 40 mm and 60mm for the bottom - it hasn't seem to make any difference
I attach some photos. Do you know probable solutions of any troubles listed? :( 翻譯年糕

those of you who use the prusa slicer for auto support generation, (Ive never used slic3r or any prusa software before), this is for you....

I saw some posts yesterday with remarkable looking results and wanted to ask a general question.

When using the app, what is the step procedure? IS it:
load stl
scale to fit build plate
optimize orientation
scale to fit (to resize it larger)
auto supports

and then what? Save as 3mf and import to chitubox or do you just slice with prusa slicer?

Hi Guys , got my first 2 prints of the Photon today , I'm calling them a success since they came out the machine in 1 piece , but there is a couple of areas I could use some advice on please . 1st 3 pics , the back edge (red circle) appear's to have sagged as well as what appears to be sagging on top sorta flat surface , Im guessing not enough supports ?? . Other thing that caught my eye is the random height lines parrellel to the print plate , I did pause the print a bunch of times to have a look see at how it was going , any possible connection ?? Last pic , this printed well except for the very bottom on the print bed , the bucket was set at 3mm above the plate in the slicer but it looks as if that was to close and the lot just sort of stuck together and turned into a solid mass , bit more angle on the bottom of the bucket and get it higher off the print bed ???. Monocure Clear resin 0.04 layer @10sec , 6 Bot layers @100sec 6.5sec off time .

Had my photon for a few months, but never actually done an exposure test :/
I know :(

So last night I ran the X3mSnake exposure test.

To be completely honest, I'm pretty lost with it.

I ran resin-test-50u.B100.2-20.photon and the result is the attached photo.
I followed the instructions, set my exposure, then printed the AmeraLabs Town test, but came out horrendously overexposed.
So despite following what I thought were idiotproof instructions, I still manage to mess up :(

I had 10 marked as the sweetspot.
So with that, I set the exposure to 20 for the AmeraLabs test, but as I say, horrendously overexposed.
When I set it to 20, I was thinking "Seems a bit high, but this bit of resin can't be wrong can it? I'll go along with that!"

After the first town test was over exposed I brought it down a bit. Reprinted. Oh. Nothing on the build plate at the end. Maybe I somehow had cured resin in the vat.
Cleaned the vat out, set it away again. Nope. Nothing on the build plate again.

Although, looking back at the X2MSnake test again, I definitely feel that I messed up.
Am I right in now thinking that 7 is the sweet spot on this test?

I'm lost :P

Hi,

My name is Peter and I have problems with my sizes. :P

An about 10mm wide part is 0.3mm bigger and a hole is 0.3mm smaller than the model.
I use anycubic resin that came with it, chitubox and settings coming from the spreadsheet.

Hi, thanks for the add! Complete noob here! Playing with the Photon Slicer whilst waiting for my printer to arrive.

Looking at the screen grab you can see that the 'loin cloth' definitely contains islands for supports but the software doesn't seem to let me add them. Is it a question of size? The whole mini is 35mm high so this gap is no more 2/3mm at most. Thanks in advance!
