You can pick up my kits at https://shop.v1engineering.com/. We’re having a sale on cracked rollers. Order now and get an air nozzle that doesn’t leak half the air before it gets to your end mill.
New video, guess a little better quality than the old one. Cutting the 3/8" tall part I put above. Everything came out nice except for a tiny bit of chatter at specific points in the finish. All in all a good run, I think I have it dialed in! Now I need to run it 8 hours a day.
5mm DOC, 550mm/s @ 11% stepover for the pocket. 8% step length, 50% width, 800mm/s for trochoidal. Total part time was around 17 minutes.
Careful with those speeds, you are limited to 120mm/s XandY before steps get skipped, you can put in those numbers because the acceleration is limiting you because of the small travel. If you really want to go faster either increase the acceleration and jerk numbers in the firmware, and/or get larger pulleys.
I was asking about a site because a friend of mine is asking for suggestion on electric skateboards.
Oh sorry, thought you were just joking. Once I get a few of these cut I will list them on a forum, ebay, and maybe amazon but I don’t know for sure. I have my design all tested for the mount, just need some more 1/4" aluminum and I am good to go for prototyping. All it will be is the mount, a 608rs idler system, and the timing belt. Want to verify it works before I buy hundreds/thousands of screws, I am sure you know the feeling.
For a LOT of information I would lead him towards https://www.electric-skateboard.builders/. That is by far the biggest electric skateboard/longboard with a lot of beginners as well as advanced user info.
Dang what a fluke, I mean’t to say not mm/m not mm/s. My brain is still calculating for 3d printing. Let me go change all of those, you must think I am crazy!
Aaaanooother update. To anyone trying aluminum, seriously get a quality air blast. Without it you are at such a disadvantage, the whole process of cutting it will just not workout nearly as good, that is if you can even finish a cut without the end mill gumming up.
Not good at all. I still use the block and valve though. I recently upgraded for actual Loc-Line, made in the USA. Wow, what a difference. For $10 this thing barely leaks any air out and has a variety of nozzle choices. Highly recommended. Now my air comes out at 40psi instead of 25, and it made all the difference. The chips evacuate so good, even at 30k rpm I am getting minimal chip recutting.
