missing .SVG slices

Hi All-

I seem to be having a recent issue with nanoDLP.  This week while attempting to upload an image sliced, the process bar initially would fail to complete loading .SVG images and and get hung up.  After a new install/upgrade of nanoDLP the process states complete.  When trying to run the process, the printer failed at around #11 slide.  In checking the .svg slices any slide after #11 was blank (all the way through #515!) Any ideas?  Computer usage is 6% so it appears that it has everything, 32GB card installed...so it should have plenty of memory...

Images are here...

Re: missing .SVG slices

Usually kind of problem happens when the source file has issue. It probably caused by imperfect support of meshmixer. Try asiga stomp to create SLC file, it is much more resilient to STL problems.
If it could not slice it, I do not think any other program could slice it.

Re: missing .SVG slices

Hi Shahin-  Thanks for the response.  I am using slic3r - and I haven't seen this issue before either.  It seems to run and slice the items fine.  But I will follow this lead.  Thank you! Elliot

Re: missing .SVG slices

Question for the Group: Has anyone seen issues with meshmixer ->slic3r before ?  Or is everyone completing support generation and then slicing to .SVG in meshmixer?

Re: missing .SVG slices

I am having problems with SVG files that worked before. Nanodlp will no longer process them. I use slic3r as well. I've upgraded to build 1221, but no luck.

At one point this message was displayed on the screen: "Problem in recently uploaded plate file has been detected. Slicer module terminated. Please, remove uploaded plate and restart system to use slicer again. To investigate problem, please contact us. interface conversion: image.Image is *image.NRGBA, not *image.RGBA"

Is nanodlp trying to slice the svg?

I guess problem is with your Mask file format, remove it to see if it start working again or not.

Elliot,
Meshmixer's supports mesh is awful as it could get. Sometimes I get surprised when meshmixer's output get processed by other programs well!!

Re: missing .SVG slices

Removed the mask, deleted plate, and re-uploaded SVG onto new plate. Still says "Plate #1 is being processed...". Preview Layers button shows no layer images.

Re: missing .SVG slices

I have tested the file and it gets sliced perfectly. I still believe bug is related to the mask file.

Re: missing .SVG slices

No mask shows up on the Setup...Projector Mask tab, so I am assuming there is no mask being used. Although, I sent you the mask PNG to see if that works for you or causes a problem.

Re: missing .SVG slices

I unplugged and re-plugged in raspberry pi and then it started slicing, but all slices are completely black. This is really weird. The home page gets this error: Skipping public/plates/5/info.json file. stat public/plates/5/info.json: no such file or directory

I'm completely stumped. I can't print at all until this is figured out. Or, is there a way to step back to prior build?

Re: missing .SVG slices

Here's what I know...

Re-added mask and got this error on home page: Problem in recently uploaded plate file has been detected. Slicer module terminated. Please, remove uploaded plate and restart system to use slicer again. To investigate problem, please contact us. interface conversion: image.Image is *image.NRGBA, not *image.RGBA

Removed mask and then the slicer doesn't work. It just displays forever: "Plate #X being processed...". No pictures in Preview Layers.

Unplug and re-plug in

Slicer acts like it is working, but the Preview Layers are completely black.

Get error message: Skipping public/plates/5/info.json file. stat public/plates/5/info.json: no such file or directory

I also tried re-format and re-build the SDCARD, re-install nanodlp. This does not change the behavior. The only thing I can think of is that using the mask file caused a problem that I can't recover from.

Re: missing .SVG slices

Sorry for the confusing error message.

The problem is indeed mask related. Convert it to RGBA (from NRGBA) and should work.
After this problem slicer module get completely shutdown. You need to remove mask and restart rpi to make it work again.

I have removed the mask restart rpi and everything working again.

Re: missing .SVG slices

I used my PGM file and resized and converted to JPG (instead of PNG). I uploaded mask and checked it was there (looks great). I restarted rpi and loaded the SVG onto the plate. It slices. But, all the preview images are completely black.

No, everything is black with the mask or with it removed.

Re: missing .SVG slices

Removed mask
installed build 1222
rebooted rpi
created plate with ring3_plate.svg
nanodlp slices
still get error: Skipping public/plates/10/info.json file. stat public/plates/10/info.json: no such file or directory
result is black preview images
blank.png
blank2.png

I don't have anything else to try, so hopefully you have a suggestion for how to get this up and running again?

Re: missing .SVG slices

I am not sure what is the problem. As I have done same thing here and it is running fine.
The error which are receiving is not important.

Could you share debug file from your installation?

Re: missing .SVG slices

Yes, you have chosen black color for rendering contours. So you get black frames as a result.

Re: missing .SVG slices

Ahhh! Nice find! That's a feature I didn't know about. Changing color to white on the profile fixes the issue.
Looks like black is the default when I add a new profile. I didn't realize I had to change it to white.
