*Update Notice* The list of issues that UVTools detects with a model is no longer automatically displayed. To see the list of islands and resin traps you'll need to select the "Issues" button. This is the button with the Biohazard Symbol at the top left of the screen.
Nice guide! The reason you don't spot the islands on the same layer is because uvtools start counting at layer 0 and lychee at one, so layer 116 in uvtools is 117 in lychee.
You are exactly right. The creator actually just told me the same thing. I really should have put that together myself, but I've never said I'm the smartest person in the room. 😂 Thanks for the positive feedback!
One of the main goals for my channel is to make 3D printing more accessible to everyone. So, I'm really glad to hear that you think this video accomplishes that goal. Thanks for the feedback! 😊
The apparent difference in layer number for island ID between UVTools and Lychee is because UVTools starts it's layer count at zero whereas Lychee starts at 1. Therefore layer 116 in UVTools is layer 117 in Lychee exactly as you eventually discovered. So add one to the UVT number and go straight there. Anyway nice video. Cheers.
It's worth mentioning that in your video your file opens with the 'issues' tab open, which isn't the default. So if someone is struggling to find the islands list, click on the second symbol in the top left. Also, saving the UVtools processed file meant I could no longer open it up in Chitubox to add the supports
That's a super important call out. Thanks for that! This video is a few years old. At the time the default for UVTools was to open into the issues tab. However, that's changed with newer versions.
Oh man I need that to be a category everywhere I upload videos... "Chill no grill informative." 😂 Really glad you enjoyed the video and thanks for the positive feedback!
Thanks for another helpful video my friend. This time I've decided it's only fair to subscribe as I've found your videos valuable to a relative technophobe printer like myself. Keep it up.
@@whatsagrinder yeah it seems like a no brainer. My guess is that some companies have approached the creator but they've turned them down. They want to program to remain free and totally accessible to everyone. I'll ask the creator next time I reach out to them. I do know that you can integrate UVTools with Lychee slicer but I've not tested that process yet.
First of all, thank you for the video! It's very detailed and it helped me a lot during my prints. I have a couple of questions tho. For example, I slice the model in my slicer (chitubox) and then open it in UvTools and hunt for islands. So, in one window I will have UVTools oppened and Chitubox in another, going after the layers. When you mention to repair the files. I save the sliced model again and press Ctrl+F5 to reload the STL in UVTools. Press repair and save. That model, will not be able to be oppened in Chitubox, right? So In order to print it I will need to use the USB stick. Right? What do you think about making a video of the complete proccess? Like, get the model, slice, fix islands, repair, print and paint? It would be awesome.
Thanks a lot for this. I imagine that when you decide to remove islands based on a pixel count (here: "remove islands that are 2 pixels or smaller"), this heavily depends on the size of these pixels, doesn't it? Because a high-definition screen with 18µm pixel is not at all the same that a screen that has 50µm pixels.
@@fluxcapacitor that's an interesting question. At the time this video was made there wasn't such a wide range of screen resolutions/pixel sizes. I'll have to look into this question a bit before I answer. 🤔
Thanks, I only used UV tools to check if the screenshot will appear all on the printer screen 😅 omg what have I been missing? 😢 I check layer by layer in chitubox, sometimes for hours. I will try this one later today for sure
I like this video, it is informative even if I will not use this technique, I just eyeball the model and orientate it at an angle that it looks like it should be okay then let it rip. My poor FEP.
I'm a big advocate for each person doing whatever works best for them. In the end all that matters is that you are happy with the results you're getting. I'm glad you enjoyed the video all the same. 😊
Thank you so much for your hard work! Very valuable information. Please tell me where you can change the language of the program to another one? Thank you!)
When i use uvtools i cant remove my supports.... when i dont, supports come off just fine. Whats the issue, why is uvtools making support connects harder or more connected?
Bonjour et merci pour cette vidéo, je viens de recevoir ma première imprimante résine et j'apprends tout ce que je peux avant de me lancer réellement et ce logiciel semble être un bon complément aux slicer qui sont parfois un peu trop laxistes sur les supports.
Instead of manually looking through 1000s of layers could I use the repair layers and issues button and get a similar results as looking for the islands individually?
The way this software fixes islands is by either attaching island pixels to ones near by or by removing them. So if you have an island made of multiple layers that doesn't have supports near it, then you may run into issues repairing those types of island automatically. But you can certainly try it!
@@SlicePrintRoleplay thanks again for the response so quick. I actually ran through up to about 250 layers manually and then just hit the button. Its printing right now and will let you know how it turns out. Have you determined a minimum pixel count you will even bother with? I’ve noticed those around even 10 or so are kind of a pain to add supports sometimes and I just skip them.
@@williamstafford7803 you are very welcome. I try to respond to all the comments on my videos. Yes please let me know how it that print turns out. As far minimum pixel size, that's totally up to you. If you want to set up values to remove islands of 10 pixels or less than definitely try it and see how it goes.
@@SlicePrintRoleplay I may give it a try. I think those little floaters that we can’t see on n the slicer has definitely ruined a few prints as far as quality. I kept having some odd spots on some prints show up where extra resin bonded. I’m guessing this was the culprit
@@SlicePrintRoleplay print came out fine. Just had some slight warping on the base of the mini I was printing, but don’t think that was from something I missed in uvtools. Wish I could send you a pic of it.
I'm not sure I understand your question. Are you asking if UVTools can repair sliced files that have islands? The answer is, yes. UVTools takes a sliced file and can edit, repair, and change it in a number of ways. However, it can only use sliced files. You can't makes those some changes to a base STL file. But I don't know why you'd want to. Let me know if that answers your question.
@@ToaChronix most do have an island detection function. It's just not usually super reliable. You can integrate UVTools with Lychee but I've not tested that myself. So I can't really speak to its functionality.... But yes it's really frustrating that slicers can't do even half of what UVTools can.
At the suggestion of you and many others, I've tried to use UV tools, only for the preview in my slicer program to become pixelated to all hell after exporting the model. Does anyone have any suggestions as to how to deal with this?
I've not encountered or heard of this issue until today. You are the second person to have this issue. I would take a screenshot of what you're seeing and post it in the UVTools Facebook group. Or open a bug report on Github. If I learn more about this video I'll post a video about the issue/how to resolve it.
Hi, I have a question about UVTools, i repair and correct all issues and save as ctb. Then i open the result file in chitubox but model appears pixeled and not pulished as original, is that alrigth?
Are you using the same or similar settings to the defaults in UVTools? It's possible there is an issue, but it's more likely that the preview in your slicer isn't displaying correctly. I'd try a print like that as a test and see what the results are.
So at the 2:50 mark I explain the different settings you can adjust that will determine how UVTools repairs the issues it's identified. Once you hit the repair button UV Tools will repair the model in accordance with those settings and how you've adjusted them. I've had great results when having UVTools repair islands using the process I go over in the video.
Repair islands will not auto add supports, it will attempt to merge with nearby blobs given your settings, it will only work with nearby stuff, far islands it will not touch it and require manual intervention
Like your video, but you are loosing to mutch time putting Supports on the Slicer. You could add those precious Supports directly using UVtools :-) (sorry the poor english portuguese fan here)
You are 100% correct. However, I haven't had enough time to test that process and I don't like to explain something unless I understand it well... Definitely something for an "Advance" video. Thanks for the awesome feedback! 😊
Why don’t we just repair in UV tools once’s it recognizes them? Why are we repairing it ourselves, I thought that was the point outside of just identifying them
@@SlicePrintRoleplay support for encrypted chitu is there, I believe readonly (unless that's changed recently) so could still do most of this workload with it. Great video and thanks for spending the time to share it!
