Well, I completed the wasteboard project, although it went through some revision versions compared to my initial comment in this post. Yes it looks like garbage, but that's okay, because I learned in the process. No big deal, because I really only abused a 2' x 2' piece of MDF, which is only like $8 from my local Home Depot. On that note, Lowe's doesn't sell MDF in less than a 4 ' x 8' sheet. Home Depot on the other hand has them in 2 x 4 and 2 x 2 sizes as well.
Things I learned in this process.....
- How to use Carbide Create and Carbide Motion
- That there is no real way to clamp a wasteboard down to the existing base in order to mill out the holes
- Eventually I had to just run screws through my wasteboard into the base to keep it from moving around
- That it is really easy to type in the DIAMETER of a hole you want in Carbide Create when it considers it a radius, giving you a hole twice as big
- That it is easy to mess up your toolpaths and think you are only doing a counter bore, when the machine is really being told to mill that size hole all the way through the stock
- That the threaded inserts do need to be counter sunk / bored in MDF, you might be able to get away with not doing this in another harder material like wood, but the MDF is too soft to not do this
- Knew this already thanks to a Winston Moy video, but since I plan on surfacing my board in the near future, you can't really have a 16 x 16 supp wasteboard on a stock S03. Mine is about 16 x 14, which allows me to hit all of it with a surfacing bit. I also can overhang this board in the X and Y dimensions without worrying about it.
- This board is just my "initial" one. I think I will build a v2 in the future, having learned all the points above, and incorporating them and hopefully not making the same mistakes again. All in all, not really a bad first project, and an inexpensive way to learn through trial and error
