it works :)thank you so much
It looks like the problem is that you zipped up your "c" folder, instead of selecting all the files in that folder and zipping them (without including the enclosing folder itself). Sorry the error messages aren't more informative.
padding out Works fine now, thanksbut i have a another problam:( i put myslice PNGs and printsettings file in a .zip file but the ember can't read the file the error that shown is : error loading file
hithe error that shown is : Print data invalid for file: c.zip: Bad file descriptor
If you'll attach the syslog file and the c.zip file, I'll take a look.
The printer's logs should have more details about the error. Go to the printer's web page (at 192.168.7.2 for USB connection), select "Download logs", and extract syslog from the downloaded file. Look up from the end of syslog till you see the error messages from when you tried to load that file. If it says UsePatternMode is an unknown setting, then your printer is still running firmware 3.0 or less. Other common errors are that the last setting in the printsettings file must not have a comma after it, and when you edit the printsettings file, you must use a plain ASCII text editor that uses simple quotation marks, instead of separate open & close (Unicode) quotes. Let me know if there's some other error.
thank for share....

If you haven't used Processing before, you'll need to install that. Then download the attached PadSlicesForPatternMode.pde and place it in a folder called \PadSlicesForPatternModeThen create a subfolder of that called \input, in which you place your 1280x800 slices. Then open PadSlicesForPatternMode.pde in Processing, and click the Run button. It will then create your padded slices in a subfolder called \output.
hiI'm confused at how to padding the slices out to 1482x1482Any help would be appreciated ...tnx
Works fine now, thanks!
Rather than putting your previously created .png slices directly into the sketch folder, they need to go into a subfolder of the sketch folder. You will need to create that subfolder and name it "/input". When you run the sketch, the padded .png slices will be placed in a subfolder called "/output" (that the sketch creates if it doesn't exist already). You can actually close the big grey screen to see the name of each slice listed as it's padded, and "done" when all the slices have been padded.Does that help?
I'm slightly confused at how to use the .pde file. I downloaded Processing, opened the .pde, put my previously created .png slices into the sketch folder but when I run it I just get a blank grey screen. Any help would be appreciated, thanks.
It wasn't a problem when I printed the test parts. I just broke one of them when detaching from the build head :) Should be more careful next time.
Nice post and new features! Just wondering why the slice_21 is empty in the test part.
Thanks. I don't know why that slice is empty. The image stack for the base plate was created by slicing an STL in PrintStudio, and it left that slice empty. Fortunately layer 22 was able to cure through the missing layer and attach to layer 19 in my test prints. But if it's causing a problem you could also just replace the empty slice_21.png with a renamed copy of slice_20.png.
