Thanks for the informative video. How about a follow up on coating types?

[markaddison]

Good vid but I notice you don’t talk about flattening bits. What size would you recommend? Also, you mention bits with 1/2” shanks but the Makita router only takes 1/4” shanks or am I wrong about that? Or is there some sort of adaptor? Thanks for all the CNC help. Mark

Thanks for the video, do you have a link for the 1/8 collett? I will be getting the Makita and want to make sure I can use the smaller bits.

Do you want to share the fusion 360 tools database for your Budget Bits recommendation? It will be great!

Is it s possible to change to collet size for the Dewalt D26204K

[allenpoling]

Beginner question. Using Aspire software. I create the sign that I want. When setting up tool paths how do I know which bit I need to use? Or is this just a learning experience?

i have a 3018 cnc machine, what is the best settings to cut acrylics, for for both rpm and feedrate, the settings i am using ends up melting the the acrylic therefore the bit

[jayceejocko]

Great Video!! I see the Onefinity cnc in the background and does it take a different collet or will it accept both 1/4” and the smaller bits? Thanks

[donaldjeansonne]

Good video as usual. Do you have info on feeds and speeds? Like apps. spreadsheet, etc.
Is such data inputs for chip loads etc really only specific to a bit manufacturer or can you use generalized data?
If not do you have suggestions on how to get informed in this area?

[ronaldhoppus]

Thanks for the tips on the bits! I checked out your web site and am wondering if you can do those inlays with this CNC? I hope so mine is on the way :-)
Also I saw someone say that the machine has poor stepper motors and undersized what are your thoughts on this.... Thanks
