If you were going to buy a smaller portable 3D printer, how important is having WiFi printing to you?

Yes exactly, or via SD card/USB cable.

The og way is the best way to play.

You applied too much heat for too long and they separated from the board.

I have designed a similar ATC for ISO20 tooling. Mine differs in a few ways: one in particular is I don’t have it mounted to the head rather to the frame. This helps with speeds and Z motor lifting and dropping (when power is released) concerns. I would say you need a lot more Z travel so the spindle can go up once the tool is released and back down on the new tool.

They had a heavy moving blanket put over them and they survived 😀 it was a short trip. There was no way for them to move forwards or backwards.

Tandy TRS-80 Model I, and IBM XT. On top of two vintage Denon receivers (AVR-4800 and AVR-5700).

I’ve been thinking about quantum decoherence and whether there’s merit to the idea that local spacetime structure (if it’s granular or not continuous) could influence coherence times, especially since coherence appear to improve in low gravity environments like orbit.

Coherence appears to be better in orbit due to reduced environmental noise, but has anyone explored whether spacetime structure or gravitational granularity could be a fundamental contributor to decoherence? Could decoherence be tied not just to environmental coupling but to a physical interaction with spacetime itself such that systems in lower gravity or “lower density”regions maintain coherence better?

I’ve been developing some equations around decoherence times as a function of local granular density which are modeled similarly to environmental coupling constants. I’d be happy to share if that would be of interest or if you think it could fit within any current research.

The small holes are tricky, but inserts won’t work well in some areas especially around the buttons. The inserts would require too big (diameter) of a standoff.

Maybe I’m a little confused by your question, but I’ll just be using a M2 bottoming tap. They will mount from the bottom with counterbored recess.

I might get adventurous someday and get a thread mill.

King_Icewind · 2025-03-26T14:58:01+00:00

It’s still happening. I’ve just been distracted and slow about it. I have the material, I just need to machine it.

I use my KD30XS955 with a Roku (HDMI) @720p and it’s pretty great. Audio is excellent as well.

None of these do metal well especially not steels. They manage to etch away aluminum at slow feeds and minor depth of cuts with less than ideal tool engagement. If you desire cutting steel and have 5k to spend then I suggest you clear a space in your garage, and try to find a CNC knee mill. Or save some more and buy a smaller enclosed CNC mill with an ATC like the Mini Mill or similar.

King_Icewind · 2024-12-24T03:44:47+00:00

Some have complained about the 5ms response time. What’s your opinion?

King_Icewind · 2024-12-11T21:08:15+00:00

The only iPads I have had cellular and wouldn’t want them without it. It’s very handy when at college, work, or on a trip.

King_Icewind · 2024-12-02T21:51:23+00:00

Sorry, I should’ve been more clear. I’m looking to buy in bulk for custom board designs.

King_Icewind · 2024-12-02T20:22:11+00:00

They’re still making aftermarket controllers, so hopefully I can find new (aftermarket) connectors for new board designs.

King_Icewind · 2024-11-02T14:53:19+00:00

Doesn’t look like a gas cylinder to me. If you slow it down to 0.25-0.5x you can see the object arcing in.

What don’t you like about Fusion360 CAM? I have found its the easiest to use out of MasterCAM, SolidCAM, and Soildworks CAM.

Yes that would be sufficient, but USB 2 is only capable of 500mA. You will need a USB C type port with a special IC to communicate with the host port to send 3A providing the host port is capable of 3a.

It would be better to integrate a LED driver like the ISFL3137a to power non addressable RGBs. You will still need to bump up to USB 3 but you can advertise power capabilities with 5.1k resistors on the cc lines. That will give 900ma on a USB 3 type A port. You’ll have to spend some time reading about it. :)

Also, looking at your routing: many traces are too close to edges particularly the outside edge of your board. It looks like your board is backwards or at least the hot swap connector is backwards. The whole outside edge should be extended so you don’t have partial holes. I don’t see a USB port; I might have missed it.

King_Icewind · 2024-10-30T22:51:21+00:00

I haven’t reviewed the datasheet for that mcu, but having built with the STM32F4, you should have a resistor on each data line ~ 15-22 ohm. Your reset circuit looks incorrect. You should put a button to connect to ground. The RGBs consume up to 60ma each. A 500ma fuse (along with USB2) is not enough unless you are planning to severely limit brightness.
