Anycubic Photon Printer Owners 造訪社團 » CURA

Hello everyone, I've searched just about everywhere for the solution and havent found it. My photons are correctly leveled, there is no z wobble, and I have had a very high success rate with using rafts. All of a sudden the rafts end up being skewed/angled instead of being all one evenly solid piece. Which results in some of the pieces I print with supports to be stuck in the raft. In the photon slicer I double check everything and I cannot figure out why the rafts are coming out skewed with some parts being stuck in them. I've even been moving the models up to 5mm above the build plate in the slicer and still the pieces come out with very short supports...the slicer preview doesn't seem to be accurate or something. Also have had an unfortunate amount of failures using this new bottle of the anycubic resin in black...was thinking it could be the resin. Thanks!

Hello again everyone. I'm in need a slicer, currently using Chitubox, that is going to keep the scaling consistent. I just sized a mini to 69mm in the Chitubox (with scaling ratio locked) positioned it, went into supports, came out of supports and suddenly he is 73.37mm in height. This isn't because of the Z lift height, I removed supports thinking maybe it was adding the Z lift height, and it was still 73.37mm. I added another model and the previous model upped to 83.46mm.

So are there other slicers others can recommend which do a better job scaling and keeping it accurate and unchanging by itself?

Many thanks in advance.

Need some help understanding how to calculate resin cost. I received my first commission and I want to make sure I'm doing it right. Is there a way to throw all STLs into a single print, slice it, and get an accurate cost? Or do I need to set each print up correctly and then slice it? is there a better way? How do I know what to set as the Resin Density?

I'm going to use Sculpt and it is a large part that has been cut up to fit on the Photon. I can print a large amount of the items on the first print, but bigger ones in subsequent prints - ends up being 5 prints @ about 15.5 hours per print.

If I'm charging about $2/hour it comes out to be about $155 if I'm doing the calculation correctly...

Any help would be appreciated.

Hi guys in new to the photon but not 3d printing (fdm)

The main issue I'm having is x & y dimensional accuracy all faces are 0.1mm larger apparently this is a known issue at the moment, i am compensating with the stl file but threads are a nightmare of course...

I know there has been attempts to make simple applications to fix this but they don't work or can cause damage ?

The main way of fixing this by looks of things would be trimming every exposure by a pixel on all "faces"

This may have been answered before,

But I'm sitting here waiting an AGE for this slicer to complete so I thought I have the time so why not ask the question.

What is the slicer using to slice?

is it using the Processor or the Graphics card?

I'm on a fairly old Mac Pro, but it's still got an incredibly powerful processor in it, but the graphics card in this machine is really terrible.

Should i be slicing with my PC which has a much more powerful GPU?

Or is the slicer just not fast and I have to deal with it.

I use Cura 4.1 for slicing FDM prints and it whizzes through in literally seconds, even on prints that are 24 hours plus it slices in a couple of minutes.

I estimate the print in the attached screenshot will take around 4 hours to print, and so far it's taken 45 minutes just to slice... it's infuriating!

***EDIT***
Can't get Chitubox to work on my mac, it loads but then screen goes crazy!

I’ve only really printed miniatures, need some functional parts, strong, hard, bit of flex, not going to shatter under impact, need to be fairly dimensionally accurate. Vinicius, Sen and other masters - recommendations please.

To be or not to be....... this is the question !

Some personal thoughts on the Photon and how to push it to the limits….

So I’m looking for a complete workflow with the goal to get the best dimensional accuracy using Photon for printing dental model.

So the main purpouse is “dimensional accuracy”

I decided to use dental resins that have a lower shrinkage if compared to generic resin. I'm testing Anycubic Dental Skin and another resin from an Italian Producer. The Z resolution chosed was 50 um, a good value for dental models.

First of all: Run Resin Exp Finder from Photonsters. This is the starting point.

It gives me a range of exposure time, min & max, and a sweet spot (even if I have some difficulty reading it..)

Once found the range of exposure, the next step is to perform other tests to validate and fine tune the exposure time.

I used for this porpouse the NestaCube file: it gives me two types of information, the first about fit (the smaller cube into the bigger): here I can modify exp time to have the best fit between the parts:

This test get us dimensional information too: i can measure the bigger cube dimensions to see if they correspond to the nominal;

And here I have the first doubt: is it more correct to adjust first the fit to have the best, and last measure the dimensions, and if needed act on scaling the model ?

Another solution could be first measure the dimensions and adjust time exposure to have correct dimensions, and then looking at the fitting and correct this if needed by an x-y dimensional compensation. The Go-NoGo Gauge test is my preferred tool for this.. (but we do not have horizontal compensation in Photon slicer and neither in ChiTuBox…. and voxelOps is a little complicated to install and use..)) ?

What is the PhotonMasters thought?

Hi Photonsters ! anyone of you Masters has tested the influence of a screen protector, like that in the photo, on the quality/accuracy of the prints ? can we use it without heartache ? It seems to be a good protection against resin over the LCD display...

can anyone tell me if the ANYCUBIC LCD Photon S could print the item below with accuracy, its a pendant approximately 35mm diameter

Printed the gauge.stl file that was put up here yesterday just to see how accurate my printer was. Below is the outside dimensions of the raised circles, I have not yet gotten around to measuring the circular holes. I used Monochrome clear with 3-60s bases and the rest at .05 with 11 second cure time. Came out acceptable as far as I am concerned. Will measure the inside ones next. Also, this was printed flat on the base.
