Oh, you can say that again! Plenty of standing and staring at something for 20 minutes pondering all possible options.The standoff bracket was my...
I have no issues accelerating horizontally at speeds up to 20m/s^2 with standard V-Slot, wheels and GT2 belt. Just gotta make sure everything's...
When you say the XYZ red lights came on, is that the HF spiking your limit lines? If they're not shielded and ferrited, that could be something,...
Ok, so, first assumption to test: does the linear rail even need to be active while reeling in? If it just sat parked up against the hard stop at...
A diagram of what you're trying to do would probably be helpful. In terms of a linear system, I'm envisioning a pair of semi-parallel actuators,...
WD-40 is not a lubricant! Initially it displaces water (hence WD- Water Displacement) and then once it dries on the surface, it actually attracts...
That's the sound of an improperly wired stepper. It's losing a phase, maybe a bad connector or solder joint. At least that's the only time I've...
The only noise I hear in the video is the stepper motor vibrations being amplified by the aluminum structure. Nothing to do with the screw, that's...
Oh, this is nice! What's the performance like? What software chain? Got any detail pics of the shoulder bolt system? Did you tap the hardened...
You're trying to build a CNC CMM, realistically. Even if you can theoretically build the thing to a sufficiently high standard, you're gonna have...
If it's that simple, I'm sure you can. It would be pretty similar to my SliderCam build, here: DSLR Video Slider From that, imagine this...
Technically one has the power capacity to do both y axis motors, but I wouldn't do that; you can run into current-sharing issues due to minor...
I'd use grbl running on a separate Arduino, then use the Pi to send g-code over serial, maintaining lots of free time to do experimental work and...
Good call on the conventional cuts, I'd forgotten about that. Seems like that would be the way to go for any lower-rigidity material. Play...
Kaizan (expanded polyethylene) foam is good for that and machines great on extrusion gantry routers. Some cases use soft eggcrate polyurethane...
6061 cuts like butter, but only if you can push it hard enough. When it comes to machining metals, you need some meaningful guide rails to get...
Yeah, it's pretty great. Even a simple 1-axis cylindrical sinker unit would be great for shops who regularly have to remove broken taps! Not that...
Ben Krasnow got his first (in a series of, by the sound of it) EDM video up as promised and the OB Sphinx gets a starring role! [MEDIA] EDM's...
Well, the xPro does have to actually tell the laser to power up. If you type in "M3 S500" (or whatever half of your $30 value is), do you see...
This is helpful, but only for a board that supplies 12V power and PWM out for a laser driver board. 12V PWM is semi-standard for lasers, but not...
