Json error

Hi,

I'm trying to use SLC files but the preview layers are always black.

Any special merge contour option in Stomp?

The log reports Json error after plate is processed.

Regards.

Re: Json error

Hi,

Could you post part of your log file?
If the preview always black, it could indicate problem with your stl/slc file.

If you could share SLC file, it also could be useful.

Re: Json error

Hi,

The first link are the part files in different formats.

The second link is a screenshot of the log.

Archivo_comprimido.zip

Sin_título.tiff.zip

I have to add that the calibration plate is not properly generated.

I hope this helps.

Thanks.

Re: Json error

I have imported both SLC and SVG files and processed perfectly.

It is the first time I am seeing "unsupported value: NaN" error, do you receive it just after reboot too?
Could you try beta version? I have updated that to make sure it print out more info on failure.

(wget http://www.nanodlp.com/nanodlp.beta.tar.gz -O - | tar -C /home/pi -xz);cd /home/pi/printer;sudo ./setup.sh

Also copy of following folder will be useful, you can copy it using winscp or a similar program
/home/pi/printer/db

Re: Json error

I'll try with the new beta version.

The part files worked on the mUVE version. I started a print, the printer moved to the position and the layer was shown on the projector. (It needs calibration for the scale).

I'll send the folder /home/pi/printer/db

Re: Json error

i've recently encountered "unsupported value: NaN" when deleting the active plate while the printer was paused, then trying to upload another plate, just as a thought.

Re: Json error

Good point, I have blocked active plate being deleted during print.

Re: Json error

I'm currently printing with your beta version.

Still some Json file not found messages on the log but the printer works.

Thanks for your support.

Re: Json error

You are right I will make log about json files looks less serious. As they are not required.
