Passthrough projects near perfect aligment


#1

I was so exited when first got my glowforge pro, to then realize that there was no program or feature to use the passthrough correctly. It was a big let down from where I had to figure out a way to properly use it. After trying different approaches I was able to achieve almost the perfect alignment and as a plus I end up with different jigs to use based on the work that needs to get done.

Also I don’t have to worry about how I slide my material. It can be on an angle or even being able to take it out and set it back in to continue cutting and still have a near perfect alignment.
I’m sure snap marks will make things even easier but I have not been so lucky to get it as of yet. I am doing just fine without it but still want to get it :smiley:

Here is some of my work. Each design was cut in 2 to 4 pieces of 8 inches with the biggest artwork measuring about 27 inches long by 18 inches wide

Love that tree.

^^^what he said.


#4

Nice work! Gonna share your method?


#5

The tree is outstanding!


#6

Very nice!


#7

You can’t just show this without telling us how you did it!


#8

Of course I will let you guys know how I was able to do it and hopefully all of you have the same results or at least make your work a little bit easier.

I will put some files together and will upload them. But on the time you guys have put some masking tape around the inside edges of the tray and cut the max cut glowforge filemax%20cut%20glowforge
This is an SVG and is ready to go. Just left click on the image and save it.

After cutting just remove the leftovers leaving behind the outline which is the max size that you can cut on the glowforge
Also here is the Illustrator file in case some changes are need it but not likely
max cut glowforge.ai (1.0 KB)

That is the first thing to do, not just to help you with the next steps but if you are like me I hate wasting material it should look something like this

Here is the rest of the files and process

After figuring out the max cut area of your glowforge with the file provided you are set and ready to use your passthrough.

I give you here several files as well as of a cut drawing of a jig that you’ll need. It will fit tight on each the side of the tray and can be slid from top to bottom. It has several lines that need to be engraved not cut. The lines will match the alignment lines that will be used later on.

There is to pieces that have to be attached with double stick tape to each side of the crumb tray. They have to be in line with the edge of the tape as well as of the inside edge of the tray. This will give a limit to how much you slide down jig.
Make sure to slide the jig up before every cut so they won’t get cut. They can stay on the laser as you are cutting, they won’t interfere with the laser as is running

Load your artwork and the alignment lines file. There are 2 set 6 lines 10cm spread apart on set in on the top and the other in the bottom, the first line will always be at the 0 point and will always be grayed out. Do try to adjust the lines or your cuts will be off alignment. Some lines can be deleted if they obstructing your artwork but do not deleted them all

!
Score your top lines to make sure that they line up with the lines of the sliding jig. This will be the only time that the top lines will be used.


Adjust the two horizontal lines that at the end of the artwork and make sure they are at the edge of your material being feed. Only select the lines an use the arrows on your keyboard, never drag them other wise the won’t end up on the right place.
Ignore the top alignment lines cut the first part of your artwork together with scoring the bottom horizontal lines as well as of the set of bottom alignment lines.

Slide your material up


The bottom horizontal lines should match with the edge of tape that was left over after cutting the max cut area file as well as of the bottom of the sliding jig.
The alignment lines should also match with the lines that are on the jig


When you are the last part of your artwork. Ignore everything else but the last part you are cutting and enjoy your almost perfect alignment.

I hope everything is pretty much understandable as is a lot more that what I normally type

When you are first going to start feeding your material do not put it all the way to the right side of the crumb tray and stay within the max cut lines. In that way if your material is not completely straight it won’t matter and still be able to be adjusted with the alignment lines

Any questions please let me know. Later on I will give you the files of a ruler that matches with the one in glowforge and also gets attached to the side pieces that will be your crumb tray

Thanks a lot! Can’t wait for the rest of the process! And your projects are great by the way.

I have a pro, and I still have not tried the passthrough. You’re inspiring me to take the leap.


#12

If you get a 48"x 96" sheet of plywood and get it cut into 5 equal pieces of 19" x 48" or even 12" x 24" the passthrough is extremely useful for cutting such pieces even if you do not use a large format design. I have used it to pack designs that together might be 20’ x 19’ or just chew on a 48" feeding it in as I went so making use of almost the whole thing.

It was those things even more than actual large format that had me go for the pro,


#13

finally had the chance to update the process


#14

process is updated maybe is a good chance to try it out


#15

Could you please explain more about what pieces get taped down vs what slides?

Yes here you go sorry I forgot to explain it.
Right click on this image and save it. This is an svg file in which is color coded and you can see the order the parts have to be put together. In the picture below you can see both. The part that slides and the one that gets taped
