We decided we’d try to break one of our ELITE series machines by pushing it to its
absolute limit, just to see what would happen - and the results are astonishing! The test
was simple…
We used one bit (¼” upcut spiral), running the spindle at 24,000 RPMs for the entire
test.
Starting at 100 inches per minute, we cut straight lines along the X-axis, increasing the
feed rate incrementally to see how fast we could get this thing to cut. If you’re surprised,
know that we were just as surprised as you… But not really.
Onefinity CNCs were designed and built to redefine the capabilities of the “hobby CNC”,
and this experiment shows just how powerful and well designed these machines are.
We hit an INSANE feed rate of 1,250 inches per minute (529.17 mm/s), cutting ¼” deep across 24”. Do you know of another machine that can do that? Let us know in the comments!

** Please note, speeds shown in this video are not factory settings. Onefinity sets the maximum feedrate to 400IPM from the factory. While we don't recommend changing any of the F1 settings, it sure is fun trying :P

Un-freakin-believable! I love my OneFinity but have never dared push it like this. It's awesome to know that it can hold up to that kind of load though. Simply amazing! Best CNC "hobby" CNC out there, hands down
Beast mode!
Morgan.... you are hilarious. You make not only interesting videos but very entertaining.
Thank you!
It’s amazing the bit held up to the pressure
Built like a tank!
When using a 1/4" 2-flute end mill at 24,000 RPM, the maximum recommended feed rate for milling at a 1 x diameter (1 x D) depth of cut is 384 inches per minute (0.008 inches per tooth). The end mill begins to tear the wood instead of cutting it at more aggressive feed rates.
It is impressive that the Onefinity can tear through the wood at 1250 IPM. As noted, this is dependent upon use of the 2hp spindle which bogged down only slightly.
Assuming the end mill is not becoming discolored from heat and the edge is not becoming dull from abrasives in the plywood, then roughing could be performed at 1250 IPM and finishing could be performed at around 288 IPM (0.006 inches per tooth) to 384 IPM (0.008 inches per tooth) or 480 IPM (aggressive, lower quality surface finish) after a tool swap to get a better surface finish.
Using two end mills - one for roughing and one for finishing - generally produces the best results and yields the longest tool life and best quality surface finish.
Thanks for the info.
So awesome!!! Thanks for putting the machine and the PWNCnc Spindle to the test!
No problem!
Hi Morgan, not in the market for a cnc router at the moment ,but if I were, it would definately be a onefinity machine (helps that i'm canadian😀)
Having a background in metalworking cnc machines , speed is great, and it also must make circles and diagnonal lines as well.
A common test that is done is a circle,diamond,and square test Its very easy and will tell you exactly how well a machine can do circles(x,y) anglular lines(x,y) and straight lines (parrallism)
The circle will help detect backlash errors and in their correction. the diamond will identify if the x,y axis are moving together correctly .
Sure would! But that wasn't what this video was about. Just showing the top speeds it can hit, and it was fast!
That's good clean American and Canadian fun!! Amazing. Put my order in yesterday!
Sure is, Eh!
Incredible. Can’t wait to get mine in a few months!
It's gonna be great!
Great to see the limits of machine. I would love to see a shape cut like a circle to test rigidity of x and y axis at the same speed! I did push my MPCNC to 2362ipm, however I had no spindle and belt driven. Fun to see limits 😊😊 thanks for sharing
we'll keep that in mind.
@ 3min "because it's an industrial grade controller.." it is very nice and appears to be a huge upgrade from 1F "previous industrial grade controller" Excited to see the upgrade path for my "industrial grade " Journeyman.
It sure is!
Just for fun.., high speed cutting a circle please 😄
I’ll add that to that to-do list 👍🏼
Let's go!
I wanna see it
Can't wait to get my Elite!
Soon!
This makes me more excited for mine!!!
us too!
I love your videos...way to push it!
Thanks so much!
Awesome video, Morgan!! Even though you may not ever run it that fast(1000ipm+) there are certainly many cases where 350-400 ipm is desirable for proper chip load.
Absolutey!
Great video. Direct and riiiight to the cut of it.😂. Always with the lil jokes😂😂. Thanks for all Team OF does. It doesn’t go unnoticed ❤
We appreciate you!
Thank you Britney! We love you too!
That was a beautiful test. I’m going to buy one of these when my newly found business makes some sales :D
Go for it!
Epic!!!
No doubt!
I'd love to see a similar test done on aluminum!
it wouldn't be as fast. Wood is much more forgiving.
@@OnefinityCNC Oh for sure, I just spent the last week cutting a bunch of aluminum parts and, while I felt I was able to increase the speed a reasonable amount, I'd love to know what the actual capabilities of this machine is with aluminum! At the very least, I know the Onefinity can go faster than the competition ;)
I’m impressed. Though this made me very uncomfortable. Every time that spindle went zooming down the rails my stomach did a backflip. Workshop PTSD.
Zoom Zoom!
You, my friend, def have a couple of screws loose 😅 hahaha jk. We all do 🤪 crazy speeds on that machine! It’s amazing it’s available for hobbyists 🤯
oh, he sure does!
Chip rate to speed ratio looked like it went south somewhere around 450 IPM. I'm glad you pointed out that although it reached 1250 IPM, the top speed was short-lived on a straight cut somewhere in the center of full length of machine as well. The actual cut rate on that pass is probably average in the 650 range, but nonetheless, you did it without snapping bit or breaking anything. Impressive is an understatement! There is no doubt about the only thing you're going to break on these machines are the bits & router/spindles because their built to last. To bad Onefinity doesn't build spindles as well 😂
The machine is a beast!
Great video Morgan! It had to be done😂
Can’t wait to see the remix 😏
Vroom!
man I gotta get that PWNCNC spindle
A spindle is a great upgrade!
INCREDIBLE! At what speed did the quality degrade? Is the X-50 that robust?
Since they share the same mechanical systems, the x-50 is very close to the same robustness!
Insane
speed!
@@OnefinityCNC when I grow up. I'm gonna be a Onefinity Elite Kid! 😁
I used my safety squints watching this one
Engage safety police!
Would be nice to see Shapeoko 4 Pro and 5 run the same thing. I have a SO4Pro so I will try to setup the same test. Which single flute upcut did you use? I have a brand new Amana one I'm willing to sacrifice for the test. Is that 3/4" construction grade ply?
Would be great to compare! Any single flute would work fine. Yes, 3/4 ply.
Wait, were you using a single-flute/"O"-flute bit?
Morgan did for this test.
Is there a file available for that top wasteboard with the integral t-slots?
Yes there is! I’m working on wrapping up a revised version with a 4x4 file so check back soon!
On our forums!
Any word on a trade up program for it yet, from a journeyman X-50?
Hopefully by the end of the year.
@@OnefinityCNC thank you for your response! Appreciate it
Personally I would like to see you do this same test with a machine that has a router as opposed to a spindle
@morganhop , can we make this happen?
SCIENCE!!!
sorta :p
any plans of making a 4x8 model any time soon?
4x4 is the biggest we have!
@@OnefinityCNC >_>
You look like a science experiment haha
lol
Well that's made the Shapeoko 5 look very conservative....
5x more conservative 😉
At what point did the cuts start looking bad?
The cuts starting at 800ipm started looking pretty bad because I was cutting perpendicular to the grain instead of parallel. But I was using an upcut bit and wasn't too concerned about cut quality
800ipm
How fast did it go until the quality of the cut was bad?
800ish ipms
That's crazy, lots of cringe watching this video. I've been watching a lot of onefinity content and can't wait to make the switch in the very near future. What kind of bit is that.
Go for it!
Ordered one a week ago. So your telling me I can cut everything at 1250 Ipm with no problems… perfect. Lol
Sure lol at your own risk! 😜
USELESS INFORMATION: 1250 Ipm looks and sounds incredibly fast, yet it is only 1.183712mph!! I was expecting it to be much faster.
But converted to metric 31,750 mm/min
1.905 kmh!
Ive seen lasers running fast. But they have lightweight heads not hunking heavy VFD spindles.
Do 1Finity know the absolute Terminal Velocity of these?
I guess no-one says it needs steppers calibrated ;-)
lol.
kinda scared to watch this
What's the worst that can happen?!
