I've seen blue at ~2.2-2.6 and red at 1.6, so as with most things, that's probably not an absolute. You'd think the actual solid state physics...
M6 tap drill is 5.0mm. Screws are usually a hair undersize for clearance. Sure it's not already tapped to M6 if the screw slides in?
If their forward voltage drop is say, 2.2V each at say, 30mA, that would be 8.8V just across the diodes themselves. On 12V you'd have 3.2V left to...
Overall looks fine, a pretty good, inexpensive entry point to machine building. Assume that it's going to be a learning process and you're going...
While I'm thinking about it, a few pictures of where everything is currently at after fixing the column plates (which I still want to paint white,...
These seem... Self-contradictory. I'd agree that moving from wheels to rail would significantly rigidify the moving parts, wheels are soft and...
Technically possible, but I think you'd be disappointed. Rails are ground, not milled, both for tolerances and surface finish. You also really...
The reduction is a necessity for servo tuning stability. If you're using steppers, you don't need it.
Single start acme/trapezoidal screws, bronze nuts and a good helping of grease. Considering how different all those machines are, I doubt I'd...
CNC is just a whole bunch of high speed pulse trains, varying analog signals, and synchronized signals. The only way to have any clue what's going...
Looks promising. Heavier plates are definitely a must, I have 3/4" and 1/2" on mine due to the sheer length of them, but these 3/8" look...
That's the same dimensions I came up with as well, so I'd have a usable internal channel for screws and maximum space between rails for rigidity....
Just noticed on these you also chose to do the "split 8080" orientation with the C-Beam. Hadn't even noticed that before. Surprisingly flexible at...
Wish AMB would let people know if the 1050 ATC works on the newish 1400. Or just bring one out for it, either way. Continuous power between them...
Definitely recommend the SMW system, works great. Probe looks good, I'm gonna build one of those at some point here, maybe when I get automated...
The AMB/Stepcraft/Kress units are all the same, as far as I'm aware. Those are what I'd recommend over, well, basically anything else, for regular...
Does the VESC project website not have info? It's gotta be similar to any other ESC- 2 wires in, 3 wires out, maybe a hall sensor plug- but...
Ok, time for another short update. I only seem to be getting one "thing" done a week at the minute, but forward progress is still continuing! I...
Linear rails allow for cheaper extrusion. Wonder how well they're aligned at the factory? Only one per actuator except for Z, so probably just...
Short-body NEMA 34 (no more than 4.5Nm) running 15mm wide, 5mm pitch HTD/GT2 belt on a direct drive 40T pulley is the way I'd probably try first.
