Cnc race!

Yeah, but there is very little power left at 50mm/s with 16T pulley’s (high RPM). I would have to change to 20T and then up the max federate.

Might be time to change the race to aluminum…

M203! You haven’t found the limit of your machine yet – it might be faster than you think!

Oh, and we need to see video too.

I had some neighbors over while I ran that…there are some choice words on the video. I was going to try and make another run, maybe try to hit :39.

The cutting forces are higher than expected

The force is strong with this one! :muscle:

Can I ask what type of single flute 1/4" mill you use? The one I’ve been using is clogging and charring. It’s somehow a different shape than the 1/8s you sell.

Let me check it was a random(expensive) purchase that has been sitting in the drawer for a while for me to get up the nerve to use it.

Now you have to find a cheaper one and tell us if it is any worse.

Well I got held up yesterday from making my video with no “french” words in it. I will try to do that first then, testing some other bits is a great idea.

Anyone have some links for some inexpensive 1/4" single flutes?

Dang they are all just expensive. I have a two flute here as well. I could try that and just lower the RPM a bit to see how it goes, they look much less expensive.

If you were to pick one of these, which would you prefer?

Here is a batch of ten for under $4 each.

I don’t have a 6mm collet for any of the routers other than the 55mm that I have not run a cut with yet.

I wish I hadn’t taken my teeny tiny burly down. That one would have been fun! So Awesome to see all the evidence for these. I also really like that Pete showed up to play. Reminds me of some of the YouTube channel crossovers, lol.

Probably.

I tried with this one on mdf:

Clogged and charred easily, quite disappointing. I guess the shape of the cutting edge and the flute matters a lot!

Fixed that for you.
