Welcome to the SB family and the forum. I see you just got your machine and that you note that you are trying to use it to make your first cut with Glitter Fun Foam and Stiff felt. Both are very ambitious project materials to start with. While I know that we all want to jump in feet first - I would highly recommend that you first learn to "crawl and then walk" with your machine before you jump into the deep end without a life preserver!
I say this both from experience of myself and all other owners who have come before you!
Have you played around with your machine and "learned" it from the beginning. Are you comfortable with setting your blade height, blade depth, figuring out how much speed and pressure you need with basic materials like paper and regular card stock, etc.? Can you easily and quickly cut and deal with the settings and such needed for basic projects and materials like that? You need to be comfortable with those things before moving on to more advanced projects. If not, you will find yourself frustrated and hating your machine fairly quickly! This is true even if you have previously used other cutters (and maybe even more so if you have used other cutters!
)
Second, cutting "glitter" anything is not really recommended - especially if the glitter will flake off. If that happens you risk getting it down into your machine and possibly causing problems. That said - some people still have assumed the risk and cut glitter card stock or paper I know
- and if you are going to try it - most have recommended that you put the glitter side down on the mat to help try and "contain" the glitter somewhat. Also note - that glitter anything will quickly dull your blades at best. If I were attempting to cut "fun foam" - I would again start with basic fun foam before moving onto glitter foam. Also, "fun foam" comes in varying thicknesses as well as "density" - so how thick (deep) and how dense it is will impact what settings on blade selection, height, depth, pressure, speed, etc. and you will probably need to use multi cuts and even then, it may not cut all the way through but cut enough to "pop it out". Same things on felt, whether or not you can cut it and cut it well depends a lot on the "features" of the felt material you are choosing to use - again starting with its thickness and density. You will also want to make sure that your media is "stuck" down good to your mat - so you may need to ensure that you have an "extra sticky" mat to work with and may want to help it stick by using painter's tape to assure good adhesion.
Learn to use the test button and scraps of material to figure out what settings that you need and even then, be willing to sacrifice some material when you are learning a new medium to cut.
Finally, you will be told that there are no "best settings" for cutting any media - that it varies from machine to machine - user to user - environment to environment - day to day - and while this is true - you can try to find some "starting points". I believe Penny Duncan has a document with some "starting points" for various media but I am not sure where it is - perhaps someone can point you to it but I don't know if it includes this type of media or not. You can also do a search here on the forum for "felt" and "fun foam" and see the prior discussions that may have been had in regards to those mediums.
Good luck. I look forward to hearing about your successes and projects as you learn to work with this great machine!
