Your optics need to be clean for passthrough projects to work well. This is especially true of the windows on the underside of the printhead.
Have you successfully used the passthrough before this error started happening? Have you tried printing one of the Glowforge files as a passthrough on cardboard? Have you tried adjusting the direct light in your workroom that shines onto the Glowforge bed?
Yes, I’ve used it successfully before. Printheads have been cleaned and cables checked. I have recently moved the Glowforge and there is a wall light not directly over it but close by. I will try turning it off! and then the cardboard suggestion. Thanks again for your help.
It’s cutting out smaller shapes on the cardboard fine but it’s when it’s set to a large shape with the pass through it’s not attempting to cut at all its saying ‘print unsuccessful’ - even when it’s a very simple shape like a rectangle.
Nothing at the sides either, I’ve also tried setting it to score to see if it was just the cutting it didn’t like and ‘aligning manually’ but since it hasn’t cut anything that’s just moving it around and it still says it’s unsuccessful.
I suggest contacting Glowforge support if you haven’t already done so. Since you have used the passthrough successfully in the past, we need to figure out what changed. You can try a different browser since you already tried a different file.
What are you shape trying to cut? In years past when using passthru, I found that a vector circle outline, , when bisected by the gf software for passthru, turned into a filled shape as it lost the constraint points.
I told support about it and then “fixed it”(aka worked around it) by making it just a rasterized circular outline.
No idea if they did anything to fix that one or not.
