Not sure why blade depth of 1 did not penetrate for you, but maybe it is related to your mylar -- jesuscf had Canon mylar that was the same thickness as Apollo stuff, but was apparently a tougher plastic and did not cut well.
You can also use the sil-studio program to test material, even little scraps. Load a bit of test material (anywhere on the mat really), fire up sil-studio, and in the send-to-cameo dialog there is a button for a test cut. Use the blue cursor buttons on the cameo to move the knife to where you want to cut, and click test cut. It cuts out a little square with a triangle inside -- you can move the head out of the way (or unload the mat) and dig out the square with an xacto, or peel of your samlple. This is a good way to try different blade depths for different materials.
Are you sure you shrunk your cream layer? I thought I had at first but got the same results -- then I used gcprevue, imported just the top-copper and solderpaste layers (which gcprevue assigns different colors). You want the layer list on the left to have paste above copper (if not drag one layer above/below the other). Zoom in and then you can see clearly whether your paste is shrunken (?), shrinked (?), ahh, reduced-in-size, as you expect.
So, is this little round board going in the nosecone of a rocket?
I have been doing alot of testing..but not 'sure' when the blade got some vinyl in it.. (not sure how skewed my data/results are now?)
either way I swapped out with my replacement/new blade.. and gave it a test again..
on Apollo transparency sheets now (write-on type..I believe to be same brand/type tested with previously here)
after new blade.. blade setting 3 was 'too' much.. ripped/merged holes..etc
blade setting two 'did' result in full penetration..
Blade setting: 2
Speed: 1, 1
Force: 8, 16
I got full through cuts..
Im not sure if I should drop to blade setting of 1, and try again?
or keep blade setting of two.. and try light 'force' values?
(if I do a single pass, do I "ONLY" have to have 1 value in the speed & force parameters? (I havent touched the others before, border or matrix..etc..etc)
this Apollo stuff seems much stronger.. and a bit more 'brittle' (at a certain point too.. if that makes sense..LOL)..
Im hoping its good for cuts and keeping shape..etc..
Good point with the Cameo test cuts!!!
Im new to the Cameo in general, as a whole.. I have only cut 3 vinyl pieces:
and the rest has been working playing with stencil stuff right out of the box! :)
I wish the pcb was for a rocket something 'er other! lol.. sounds like some fun! woot!..
but alas.. not as adrenaline pumping at that.. :)
was the end result of a 'goal/project' I gave myself.. to retro fit a Spider-Man webshooter prop with some electronics..
the space was VERY (very) tight.. (height was a killer, since almost no components could populate the top of the pcb.. and the bottom has a microSD card!.. and the pcb isnt much bigger than that!
Was really just a result of a bunch of things I hadnt tried before
custom shape pcb in Eagle (also just square/rectangles)
Arduino running on internal 8MHz clock
just some things I had not ever tried.. :)
I'd like to hear about the results/speed (and then of accuracy after speed) of the optimized.py script as well?
I 'do' believe I have shrunk the cream layer*..
I open up an original and a new one I did after 'shrinking' in Gerbv and sticked and turned on/off the layer.. you can see the original was is 'bigger'...
that being said though... I have NOT been able to shrink it past 4mil?
I type in 6 mil.. and run CAM JOB.. (iTeadStudio CAM file, because thats who I normally use)..
I know its a bit different than the one you are used to..but it how they have their fab house set-up..so I just roll with it!..
(this is where/how the dimensions 9pcb outline/shape0 layer is included as well for them)..
anyways.. I go to 6mill shrink on CREAM layer.. export.. open and check it against the 4mil.. same thing!..
not sure if running another/different/alternate CAM file will allow this? and theirs blocks/stops/limits it?
I'll try to figure out to do a single pass..
and do another test before trying another export CAM job..
thanks! couldnt have gotten this far without you the help of others here.. thanks!
