Having some trouble calibrating Chitubox to my Original Photon.

Basically it squashes/stretches the image across the z axis. I plan to print some parts that need to be exact dimensions, and would really like to get this as close to perfect as possible. I’d also like to use Chitubox, because I can save the project file with supports in case I need to edit revisions of a print.

So...

I’ve ruled out the z rail calibration in firmware, since I can get a perfect print using Photon Workshop. That print is far left and it’s height matches it’s width (as it should).

On the far right you can see the same STL sliced in Chitubox using the default setting for Photon original. Notice the width is slightly wider than 5 cm, but also significantly shorter height. It’s visibly squashed even without a grid.

When I posted about this before, one of you told me the default dimensions for the Photon in Chitubox are wrong, and suggested new settings. I’m away from my computer now, so I don’t recall the exact ones suggested at the moment... but you can see an improvement in the center print. That said, you can also see that it is still slightly skewed (a little wider than 5, but just about on 5 tall)

Soooo.... I know I’m on the right track, but I also know the settings previously suggested are slightly off. Anybody have this dialed in perfectly, and can suggest the exact dimensions and margins to use in Chitubox for the Original Anycubic Photon?

I need some help with stretched prints.

Using an original Photon and Chitubox. Anytime I print something relatively tall, I can see stretching on the z axis. This one in this photo was actually standing on it’s edge for the print.

I’ve tried previous advice on changing z size on the printer profile to something like 150 instead of the recommended 155.... but that made no difference whatsoever (as expected).

What else could be causing this?

Finished this Gryffindor Wand Holder for my daughter’s birthday tomorrow. My second non-modification print since starting.... and I’m loving the results so far!

eSun Transparent Bio at .024 10s. 3 pieces. Based with spray paint and then details with citadel paint.

Hello!

I’m fairly new to this, and need some help. Been printing for the past month occasionally. All prints have been successful.... EXCEPT when using eSun bioResin Grey. I’ve had 100% success with their transparent bioresin as well as their hard tough... but can’t get a print to work right with grey.

Using an original Photon and Chitubox to slice (medium auto supports, minus a few that didn’t look necessary). Trying to print 2 simple tests to dial in a good exposure for this resin; an FEP puck and the One Ring.

I’ve tried quite a few combinations, and these settings were the first to actually make something. Even exposure time 17s failed during the supports, and anything like 12s or under didn’t even get nubs where the supports should’ve been. However, at 20s, all the detail in the Ring is completely missing and the supports for the FEP are a solid chunk. I’m assuming this is from overexposure.... but not experienced enough to make that determination.

I could keep dialing in between 18-19s, but before I waste any more time doing that... I was wondering if I could be doing something else wrong. Can 1 second make that big of a difference between a total failure and doing even the most basic detail? Any advice is welcome!!

I feel like I’m using too many supports, but seeing how they were failing at lower exposures, I didn’t think it’d be an issue.

I can’t figure out why this resin is so difficult. All the others have had significantly lower exposure times (6-8s) and first time flawless prints. I’ve been told grey is best for reproducing details, and have been trying to dial in my settings so I can use this for the detailed models I plan to print. Am I wasting time with this resin?

P.S. Before making recommendations to switch to a different brand, I live in Thailand and resin options are limited. eSun is readily available and in my budget. I could give up on the bioResin or just the grey... but most other brands aren’t an option.

Thanks in advance!!

First time using a solar turntable... this is awesome!!!

Had the Photon for a little over a week. After the initial cube, and then a vent modification, these are my first fun prints. A pair of baby yodas in carbonite. They look good painted, but they didn’t come out perfect, since I’m still learning. Any advice is welcome!
