Just putting it out there for other hobbyist CNCers: Whenever possible, check the CNC's manual for recommended maximum spindle speeds and feed rates. Consider those numbers to be your absolute maximum--anything above MAX is changed to MAX. Anything below MAX becomes the new MAX for this project. Next check the bits you will be using and adjust your MAX and min values to be as close to the bit manufacturer's recommendation as possible. That will get you all started. People try to do these feed rate and spindle RPM adjustments on the fly, but that is probably what caused the problem in the first place. For example, plastic will melt if the feed rate and spindle speed are too high. Metals will react differently depending on the type and whether the metal is pure or an alloy. Sometimes the incorrect values will cause the material to work harden and destroy the tool. How to fix that depends on the material and the tool; fortunately, manufacturers have spent a lot of money figuring out the correct values so you wouldn't have to.

@@AmyMakesStuff I occasionally cut plastic at work, or talk to machinists who do, and the big things are: (a) have a super sharp cutter with as few flutes as possible. we use robbjack at work and they do a pretty good job. (b) get a compressor and blow air on the cutter -- this helps evacuate chips and cools the cutter so you don't melt the plastic. some plastics make "stringy" chips which can wrap around your cutter and ruin it or the workpiece (c) play around with feeds and speeds until you find something that doesn't melt the plastic. even though you can probably get away with max spindle speed, it may generate so much friction it'll melt the part. a slow feed and medium speed may be your best bet. your flexure parts remind me of the wire EDM work I used to do at my last job -- flexures are a super awesome way to make moving parts and i'm really impressed with your work! keep up the great work!

@@AmyMakesStuff your video is another masterpiece! You're definitely good at this

"I can't believe that you made it this far", you're just so humble. I enjoyed every single second of this video

The tool most likely stopped due to excessive vibration. You can't climb cut with a tiny tool with that much of the stock sticking out. Climb cutting is where your tool pulls itself along while cutting. This also causes tool deflection. Try to cut towards the cutting edge instead of away from it. Also leave as little stock sticking out as possible to reduce vibrations.

Hey Amy! I only just stumbled over your channel an I have to say I really like your approach on creating videos. You clearly state the reasoning behind your designs and also share your trials. Also, your honesty about your experience with the CNC machine is great and is a sign of integrity! I look forward to seeing more of your videos. Keep up the good work!

Amy, I genuinely appreciate your transparency and integrity in making these videos. Subbed, upvoted, impressed. Keep up the great work.

Great vid, Amy - I love your stuff! I particularly enjoy your material on flexures, it’s informative and inspiring. I feel like it takes a different thought process (or at least a modification to my current one ;-) to think of flexures vs other more conventional construction. Your content on flexures plants little seeds in my head about them that I know will someday bear fruit in a project where they’ll be a perfect solution for my needs. Thanks again for your great content, keep it coming 👍😁

I like your chill/laid back nature while doing so much cool stuff!

I always appreciate makers sharing their trials and tribulation. Its a much more honest and realistic demonstration of the design process I wish more employers were aware of 🤣. This toggle reset is an awesome design. Any chance you're going to sell some of these? Between my two cats and my dog, something like this would sure come in handy!

I have had the exact same "pausing" on other cheap cnc machines, and have come to the conclusion that it is due to electrical interference on the controller board. There are a lot of possible fixes that you can try such as grounding the spindle motor, and adding ferrite to cables (I went with wifi to completely get rid of communication issues), as well as grounding the bed.

@@aaronwilliams7062 That would be my guess here too - since this happens only when cutting metal, it is likely the drivers simply overheat due to the extra load being put on them. And once that happens the thermal protection kicks in and shuts the machine down.

Great video! Your flexure demonstrations are fun and easy to understand. Seeing the reset on day change was really satisfying. I also liked how you compared the linear flexures and pointed out the differences in deformation w/ and without nesting. A lot of other flexure videos are simple mechanisms that move then go back to their resting position, the end. I like how your projects have a theme of memory or saving state of movements, each advancement of the claw moves forward a day and the toggles save an on/off state for tasks. Thanks for the videos!

Well done Amy, it's fun to follow the process of invention and fabrication. Your designs are similar to MEMS devices I've seen -- Impressive. I think you have a bright engineering future ahead of you. The world is your oyster (as they say) -- yes, I rolled my eyes when I was told that when I was 17. At 62, semi-retired from Microsoft (xBox, DirectX), telecom startups, and Amazon Kindle Fire, I am still inventing, patenting ideas, and selling products I designed. I can and do use Solidworks, but I often use Fusion 360 because of the CAM (and for fast patent drawings), so I can drive both my large VMC CNC Mill, and a small one like you were asked to use (with the same issues). Right now I'm hiring some DARPA interns to help me on some very fun projects... anyway, keep up the good work and showing us the way.

Yay! Flexures are good and your like is well earned. Very cool

I learned something about flexures... thank you.

Noice! Always love to see some awesome flexures. Two things about the CNCing process. 1. A large amount of that play seems to be due to a massive amount of end-mill runout. Around 1:26, you can see parts of the spindle vibrating. This could also be related to why the sound was so bad. 2. My guess on why this machine would not machine metal has to do with grounding. Sometimes, an improperly grounded controller or motor driver can reset the spindle and/or entire machine, similar to what you ran into. A grounding wire on the material/bed/chassis might help.

@@AmyMakesStuff Not to sound insulting, you clipped the collet INTO THE NUT FULLY, before putting it into the machine a few turns, then sliding the bit into the collet and tightening, right? I've seen 3 makers on here, place the collet into the nut without pushing it in til it clicked, just loose like a dremel collet, then putting the bit in, then tight tightening it onto the spindle. TONS of runout. The collets clip into the nut with a loud clink, they don't float. The reason the machine stops on metal is because it's shorting out. It has nothing to do with LOAD (like oh no, brass is so much harder to cut! spindle overloads and turns off due to heat/current. Nope.) Unfortunately this is a well known problem with pretty much all these tiny low-budget cnc machines. The good news is, the fix isn't expensive OR difficult. There's videos here on youtube about it, search "spindle grounding cnc" and also "spindle emi cnc" emi = electromagnetic interference. This is what's crashing the control board, turning the cnc off (spindle stops, stepper motors stop moving. it crashed and rebooted.) It's kind of a common problem, not just on inexpensive cnc's, but even big DIY cnc's! I just came across your channel and dig it. The idea for this project is great. No way it would work for me with my puddleofdogs, but a great idea none the less. GL, and check the collet and nut! Take it off completely and inspect it. Make sure there's no flashing or crud stuck in the cuts/slices in the collet that would keep one area from flexing properly as it gets cinched in the taper, and make sure it fully seats in the nut, and can rotate freely once it's clipped IN to the nut (out of the spindle).

Sounds like you (Amy) could verify / try temp fixing this by mounting the metal workpiece on top the plastic "sacrificial" plate like you did the calendar parts to insulate it from the metallic work surface. That way contacting the metal workpiece with the tool should have no electrical effect. If that "fixes" it, then it confirms the problem as stated above and you can pursue the ground and shielding methods knowing you aren't wasting your time chasing imagined fields and electrons ;)

" can't believe you've made it this far" ..... You showed up on my suggest videos. I will be happy to give you my criticism...... I have none! You do a great job on your videography and narration.
