Shapeoko CNC From Scratch: CNC Cuts
HTML-код
- Опубликовано: 30 июл 2024
- This video is intended to cover the basic cuts a CNC machine can do. It covers contour (inner, outer and no offset), V-carving and textures. I will cover 3D in it's own video, if I can ever figure it out well enough to explain it.
The plan with this video is to make a series of extremely basic videos for CNC. We will start here with what can be done on CNC, next we will explore the Carbide Create designer and see how we can setup a new project, draw our lines and shapes, do boolean operations, edit nodes and more. The third part will cover how we set tool paths, select and add bits as well as preview and save our gCode. The fourth part will finish up by covering setting up the machine for cutting, bit changes, rapid positions, work holding and repeatable cuts.
I will likely alternate with some project videos to keep things interesting for everyone.
The use of the pen to draw on the MDF is taken from the same technique I used in my "Shirtpoko" video:

Awesome video, explained very well for a novice to understand
All new to me cnc world. BRILLIANT thanks John
Well explained John even though I've been using a CNC for a few years now. Certainly a good demo for those new to CNC machining.
The best intro to CNC that I have seen yet. Thank you so much
Much appreciated :)
Thanks, I learned a lot and now maybe the frustration level will go down.
good one! You saved lots of us a lot of testing time
Thank you for this clear explanation of basic cuts and how they are used. This was a well explained and very useful video presentation. Thank you, John, for spending the time to prepare and capture this work on video.
Thank you for doing this. I look forward to the series.
Thank you John for putting your time into your videos. I always take away some great ideas from your shared information.
Well done. Concise, insightful and highly informative. Cant wait for more content.
Love your videos. Learn something every time. Thank you.
John, this is a wonderful video and is helping me bridge the gap between woodworker/artist to working with CNC.
Thanks so much. That is very much where I am targeting things.
Exactly the information I was looking for. Please keep them coming. For some reason your explanation makes sense to me. Subscribed
Well done John, I have picked up more through your video process therefore making working with my Shapeoko a lot more fun.
Excellent!
Can't thank you enough. Great video, just got my shapeoko 4 and I'm new to cnc routing. I'm excited and terrified lol. Excited to learn more about the software and getting something cut from start to finish. Thank you
awesome video...I am in the process of hooking up my OneFinity CNC and and am new to woodworking...I will need to do similar tests to learn about the bits and software. I like the marker method
I love playing with pens. CNCNutz has a great tutorial on building a pen holder with a spring. I am eager to try it: ruclips.net/video/6I9Hgcb75XA/видео.html
@@johnearlclark thanks
Feeds and speeds aren't about making your machine go faster. Getting those right means getting the most out of your machine - yes - but also your bits and your material. Going too slow can sometimes be as bad *or worse* than too fast. In materials like MDF (which likes to gum up multi-flute bits), going too slow can even start the material on fire.
I do understand, but I simply wanted to convey my impressions of the forum as a new user. People approach new processes in different ways. I came to CNC to help me make things. Efficiency was very much secondary to me. I am happy to use the defaults in most cases. I saw so many forum discussions veer off into discussions of chip load, when all the user asked was how to add a new tool to the library. They are my target audience, so I deliver the information in a way that I hope they can absorb and use to achieve their goals.
That said, I would absolutely adore it if someone made a beginners video on chip load that did not sound like an engineer and a lawyer arguing in Ancient Sumerian. That would be amazing and I would watch the heck out of it.
Brilliant explanation John E. I think this should be posted to many CNC groups for newbies & even experienced CNC users to get better understanding of the relationship between bits & cuts. (Do you mind if I cross post to a few groups?)
Btw. English being very imprecise, The extra time taken for 1/8" cut over 1/4" isn't surface speed of the bit, more the amount of stock removal per pass, 1/8 has to do more circuits. In theory the 1/8bit can safely travel faster then the 1/4. But assuming same feed rate, still longer time for extra passes.
PS. Looking forward to the follow-up videos, sounds promising to be educational & improve efficiency, which in turn improves speed without breaking bits!
Feel free to share.
Great vid. And naturally I won’t wait till the end to find out if you answer. But my question is this. Inside & outside of a line is normally is a line that has no thickness. Your lines have a thickness. Are you accounting for it? If you address this later in the vid just tell me to shove off.
I am not actually sure how the inner to outer boundary of the line is handled. When I pull things over into Inkscape, the line is .01 inches thick. It may be that the line is representational only and the actual cut is from the center of the path and not the edge. As I mostly deal with wood, .01 inches hs never had much of an effect on what I do. I am betting the guys who work in aluminum would know for sure. Good question though. I will ask around.
A/C noise is no problem at all
I was an audio engineer for years and I have to keep reminding myself not to stress so much about outside noises. :)
Excellent explainer. Question for you though. What software did you use to create those randomized texture patterns?
It's part of the toolpath selection in carbide create. carbide3d.com/carbidecreate/
Thank you so much for explaining this with the bits and dialing down the explanations. Companies that make the hobby CNC machines seem to leave out the education for visual learners. Also, would you be willing to accept funds to contribute to your wood/mdf use on these tutorials?
Thanks so much. I am so glad it helps. Since you are the second person to ask, I went ahead and set up a Patreon page. Donations are always appreciated, but I am also happy if you just keep watching and find things useful. www.patreon.com/povcnc
