Pushing My CNC to Its Limits! How Fast Is Too Fast?

How fast can a Hobby CNC run? Ryan pushes the limits of his Onefinity Elite Foreman to see what feed rate his beginner CNC can handle.

So to clear it out, you have a CNC that is tracking each step on the stepper motors (feedback) so when you hit the first problem in cherry and it skipped a step it stopped the program. This was also the same time when you should have known that the bit is stronger then the stepper motors since it lost a step. (aka nothing is breaking). Looks like a really great and strong bit and I think the worst you can do to the bit is running it to slow so it rubs and gets to hot and after that it would probably break before the machine lose steps. Anyway great show and the OnefinityCNC clearly shows it has enough power for a hobby CNC. As long as you don't modify the max current to a motor I would not expect anything on the machine to break except maybe a bit.

Greatness! One of the few "woodworkers/CNC Woodworkers" on YT that actually WORKS & SHOWS vs Promoting nonsense!!
I salute you Sir 🫡

All that is happening is the steppers supplied with the Elite are erroring out. Masso doesn't even sell those steppers to the general public. Add the 2Nm or 3Nm steepers even with the 36v power supply and you could cut at those speeds.

What I’d love to see is more dynamic cuts. Doesn’t have to be as fast, but let’s cut some shapes. Let’s see elite handle direction changes.

I have to assume this machine has closed-loop steppers, right? That's how it was able to stop when the load was detected as exceeding some threshold. My machine, which I built based on the PrintNC open source design, currently has open-loop steppers, so I'm pretty sure mine in a similar stress test would have snapped the bit (hopefully embedding into the wood and not becoming a projectile, but good call on wearing your eye protection) and then continued along the path. My machine is definitely more rigid than the one you're using here, so I gotta say it's eye-opening to see how much faster I could be pushing it through wood than I have been, and that roughing bit no doubt is playing a key role in that too. Thanks for running this test and sharing the results!

Great video! Next video: Running bits through aluminum at different feed rates

[JTWoodworks]

This is pretty wild!! What was the RPM of the spindle? Was it the same for all the tests?

[lesterandreas]

It is Sunday correct……..That was very impressive even though I already knew it could do 1, 000ipm due to your livestream. Let’s try it with some arch cuts and find out when it breaks. You have me almost to the point where I want to purchase one.

This machines pretty hard to break. I just got a brand new one, and me being new to CNC’s accidentally shoved my PWN spindle straight through the wood because I didn’t zero out after bit changes. My heart dropped, but was genuinely surprised nothing broke except the wood of course.

[ashleehouse]

Squirelly haha! That is impressive. Awesome video.
I vote hang both panels on the back wall.

[lucasalati]

Impressive bits! Great video as usual man!

[OnefinityCNC]

The Onefinity CNC certainly didn't brake! The spindle cannot keep up with the power of the Onefinity! The spindle stalled.

[AquaVitaeWoodworks]

Great video! (And Thumbnail too) I’m not brave enough to test my machine like this 😂

[MacProwler]

Man that is awesome. I wish I owned a cnc machine that could run that fast. However, I never would use it at that speed, but the bit is what really impressed me the most. I have got to have some of these bits!!

[douglassmith]

What failsafe in the one finity was tripping the stop?

[matthewbaker]

find as many different types of wood as possible, build a "collage" feature wall on the side set behind all your hooks
maybe neaten up the the speed rate by carving out and filling with some black resin

Upgraded from my original 2020 Woodworker to an Elite Foreman last month and about to finally put it together this week. Thanks for breaking your machine so I don't have too! Are these chipbreaker bits you've designed for hogging out material only, or also for smooth finish too?

[mikehurst]

So what did break or mess up at the end when you ran it at 1500? You never said in the video

[dfgaJK]

Time to turn up the servo drive current!

[davobonbon]

Can it go 1, 500 ipm without any wood there?
