@niget2002 I think your comments are right on.
I’ve seen lots of cool things made here.
And it seems people are doing some amazing stuff. And I think it’s cool that more and more are mulling aluminum. That should show the MPCNC at least can do it.
Sure this isn’t going to blast through metals in a few minutes. But for the price, the learning experience and support, I can’t see knocking the project unless you’re like the guy I saw who doesn’t get that if you don’t follow the recommendations then you’ll have poor results. Hell if you want to try your own things, great, but don’t blame it on the design. Accept that you are pushing the limits. Otherwise go with what is known to work and then make intelligent comments.
