I tried milling a small hole (about 1/8) in 1/4” aluminum but only managed to snap endmills. (Lucky they’re cheap) I used Fusion 360 and helical...
Just to be clear. I haven’t tried the thrust bearing approach yet. (I’m trying to keep to one project at a time). I would love to hear if it works...
Standing the machine on the screws seemed a bit unwieldy! I think just clamping a block of wood to the screw should be enough? Your comment about...
I agree that the clamping style collars works a lot better. The 5/16 ends up being 7.94mm so it’s a nice fit for the OB leadscrews. I think that...
I lime the idea of heat, albeit it seems a bit impractical. But let me see if I understand what you are suggesting. The idea would be to: 1....
This turned into a hijack of this thread. If you want to follow this discussion you can check out Sphinx lead-screws in tension
Hi An interesting discussion started in another thread (10mm Leadscrew in C-Beam Build) and I figured it would be worthwhile to break it out into...
Interesting. I’ll have to peek at the machine to see how that would work out.
I love the box idea! Might have to steal it! How do you like the 400w spindle?
Well yes-ish. It would require me to disassemble the machine to flip the end plates. Also I might need to increase the length of the spacers for...
I’m running a 1x1 Sphinx with 8mm screws. It works but it is actually not very confidence inspiring at higher speeds. It seems like the critical...
Do you have a specific use in mind for 4x8 or is it “just in case”? If you’re a hobbyist like me then you’ll likely be routing stuff less than...
The only problem I had with the Dm542 from stepperonline was that I had to disable the idle timeout in grbl. It seemed like the drivers needed...
Thank you for the answers. What I mean is the Sphinx has two pulleys you couple the stepper to the lead screw. I’m plan on to stick with this at...
That looks nice! I’m going a bit less beefy. 12mm round rails and 12mm ball screw. Unless I start upgrading more things then this should be the...
I believe the counterbored holes are on the end plates for X and Y axes. The only threaded holes that comes to mind are to mount the steppers on...
Andreas Bockert published a new build: Upgraded Z-axis for Sphinx-style CNC using ball screws and linear rails. Read more about this build...
I read recommendations for air tool oil somewhere on the internet.
What are you planning to use for movement? Belt or screws? As Rick mentioned, you should to add some 90 blocks to the inside corners to increase...
I finally got around to upgrading my controllers from DRV8824 to DM542T from stepper online. They're running with 1/8 micro stepping. I was able...
