There is no reason to be any taller than your longest end mill. For a 1/4" end mill, that's no more than 4". With a palm router, you'll end up...
Yesterday, I sadly took apart the Sphinx. We won't forget you. Moving on, the stand is built and the enclosure is in place. There is a single...
It's impossible to provide any information without having exact specs. Are you positive that it's 1" and not 25mm? What is the outer diameter of...
Backlash comes from tiny gaps between components. In this case, it's created by the tiny spacing between each gear in the gearbox. The more...
The first thing you need to do is set expectations. Size (x, y, z) Materials to Cut Cost Tolerances
Are the stepper drivers constantly energized? See Quote There is also the great possibility of backlash. This is what would let you turn the...
If you think the world of cnc will be all sunshine and rainbows, you have a lot coming. The missing parts is one thing, but expecting to never...
The holes should technically be undersized, otherwise the bearings would just fall out. If truly is that big of an issue, just take some 320 grit...

It actually makes sense. At 1000mm/min, the stepper is spinning at 300rpm. We also have 450rpm at 1500mm/min. Taking a look at the torque...
Sorry, yes I meant mm/min. One thing to keep in mind is the drive reduction. The 1300ish ceiling would be 3900. It's set to 1/4 stepping....
Phoenix controller with DQ542MA drivers. 10mm pitch ballscrews 1/4 stepping = 800 pulse/rev 1:3 gear ratio...
IT'S ALIVE!!! With the gear reduction, the steps/mm is 480 at 1/8 microstepping. I dropped it to 240 at 1/4 due to serious step loss, but the...
For perspective, I'm 5'9" (5'10" on Tinder). The hood will have to wait till tomorrow. I'll dump a gallon of polyurethane onto this thing after...
I still have quite a ways to go, but it's progress.
"Mommy, how are CNC machines made?" 200lbs worth of MDF later.
Are you regularly cutting aluminum, or is just a once in a while thing? Anything can cut anything if you take light enough cuts, but I would...
That just seems like you're playing with fire for no reason. In most situations, a machine is only using about 2/3 of the total rated current....
I definitely got it tamed though! The only cable missing from the "spine" is the limit cable. The limit cable is a five conductor double...
One decision I absolutely regretted when I built my Sphinx was my "form fitting" wiring. My wiring from the machine was just long enough to get...
