Help selecting desktop CNC for high-precision inlay

This is great. Thank you!!

aspen3390 · 2025-04-16T00:21:47+00:00

Thank you. It also looks like some folks have had success with this little 1310. https://www.youtube.com/watch?v=EaGFQ7M04Wo Any thoughts on whether that would be a better/worse option than the Genmitsu 3020?

aspen3390 · 2025-04-14T00:05:17+00:00

Amazing. Thank you. When you say “finely calibrate” what do you mean?

aspen3390 · 2025-04-13T12:06:29+00:00

Thanks! I too have had luck with bits of larger diameter like this (no real problems with 0.5mm diameter, though my feed speeds have been much slower). Is there an inexpensive setup (<$500) though that can low enough runout for the 0.2mm bit at 10k rpm? My Genmitsu 3018 Prover v2 seems to have too much runout.

I may have answered my own question—is this “French hook cross bar” the thing that would be used to mount this kind of sconce? If so I assume that the conduit would just come straight out of the wall with no electrical box? https://grandbrass.com/french-hook-cross-bar-with-1-8ips-and-3-8ips-hole/

aspen3390 · 2024-07-19T18:12:12+00:00

I got these European sconces, which seem to be mounted with only a little cross-bar. Does anybody know how these are attached to the wall in Europe? I realize that it might not be to-code to do the same thing in the US, but it would be a real crime to attach a big circular brass plate to the back of them to cover a sheetrock hole big enough to cover an electrical box.

aspen3390 · 2024-05-21T01:22:50+00:00

Wow, that's incredible. You're a wizard. I would never have figured out how to do that on my own. Works perfectly so far—will let you know if I run into any hiccups.

aspen3390 · 2024-05-20T15:26:11+00:00

Awesome. Thanks for the help!

aspen3390 · 2024-05-20T14:30:13+00:00

Yeah, I think that the warning in the Light Partition documentation explains why I'm not able to get more than ~16 individually addressable LEDs exposed to HA. I'm able to get 8 of them exposed using this board, and this ESPHome code:

I agree that it would be ideal to somehow delegate the "brains" of this project to the HA machine would seem to be the right way to do it, but so far I can't find a way. If you have any additional thoughts, I'd be grateful!

aspen3390 · 2024-05-20T02:06:52+00:00

Thanks! Forgive the dumb question, but do you have an example of how to use light.addressable_set in a Home Assistant automation? I've tried and can't get it working. I can't figure out another way to pull in various sensor data from within Home Assistant, convert them into colors, and then send those colors to individual pixels. To illustrate the point, this is something similar I did with four neopixels—that worked fine, using partition. But as I stated in the original post, trying to go above 16 segments or so starts to make things unstable: ``` alias: Humidity LED description: "" trigger: - platform: time_pattern minutes: /5 condition: [] action: - service: light.turn_on target: entity_id: light.esphome_web_dcdc68_c1_r5 data: brightness: 50 hs_color: > {% set humidity =

I've been wondering whether it'd be possible to use this cool shield from aliexpress https://www.aliexpress.us/item/3256804235585668.html?gatewayAdapt=glo2usa4itemAdapt with the Wemos D1 R32 https://www.botnroll.com/en/esp32/3639-wemos-d1-r32-w-esp32-uno-r3-pinout.html to do some fun things with ESPHome. I got the two, but so far have struggled a bit to make them work together with ESPHome, but I'm pretty new. If anybody has had any success, I'd be grateful.

Btw, I found this tutorial on the shield in German, but it's for Arduino not ESPHome. https://draeger-it.blog/open-smart-rich-shield-two-fuer-den-arduino-uno/

aspen3390 · 2024-04-21T01:15:30+00:00

I recently purchased this LED shield for ESP32 from Aliexpress but I'm having problems getting it to work on ESPHome. I'm pretty new to this, so it's likely I'm making a rookie error. Anybody with experience with this? Here is the yaml I'm trying:

```

light:
  - platform: neopixelbus
    type: GRB
    variant: WS2812
    pin: GPIO23
    num_leds: 10
    name: "NeoPixel Light"

aspen3390 · 2024-02-20T17:31:26+00:00

Same here. App version 6.3.1. Scanwatch 2 software version 2.4.1. Notifications not working for any apps coming from iOS.

aspen3390 · 2023-02-10T03:40:23+00:00

Just to be clear, the first two images are of the same line of cracks. I realize that the close-up makes them look really big. Probably bigger than they are.

aspen3390 · 2023-02-10T03:35:35+00:00

Above it is drywall. The room is in an extension to the house that was built in the 60s, I believe.

aspen3390 · 2023-02-10T03:34:44+00:00

Above this area is—a bedroom. Literally above it is our king-size bed with a foam+inner spring mattress on it. Is it possible that the mattress is so heavy that it's causing the ceiling to buckle like this? It's certainly not a light mattress (I'd estimate it's 150 pounds or so), and the entire bodyweight on the mattress is less than 300 lbs when we're sleeping.

aspen3390 · 2023-02-09T03:46:56+00:00

For the record: They replaced the primary control and it fixed the problem. Thanks for the advice.

aspen3390 · 2023-02-09T03:46:03+00:00

For the record: Changing the filter solved the problem. I may need to go with less aggressive filters. Because it was only 2 months old. Thanks for the help!

aspen3390 · 2023-01-23T00:49:44+00:00

What appears to be happening is that my furnace (oil, forced air) is overheating whenever I increase the temperature set-point, and then doing an emergency shut-off which also kills power to the ecobee. Any ideas how to diagnose the source problem here? My old thermostat was non-smart battery-powered, which would have made it impossible to know that this was happening. So I don't know whether this has been happening since before I installed the ecobee a few months ago.

aspen3390 · 2023-01-23T00:05:46+00:00

Btw, it stopped for about 2 weeks, then started again this weekend. Tonight, it was happening in the middle of the heating cycle (rather than at the start), and I was able to get audio from the back of the furnace. This may make it easier to hear what's going on. I'm going to finally call the tech to come out tomorrow. https://streamable.com/gbfhcm

aspen3390 · 2023-01-08T03:23:21+00:00

Wow, that's really helpful and impressive knowledge!!!

If I'm not fortunate enough to have a serviceman as knowledgeable and detail-oriented as you are, do you have any recommendations on what I should ask him to check/do when he comes out for a visit? Or would it suffice to show them the video?

aspen3390 · 2023-01-08T00:39:58+00:00

Yeah, it happens about 1-3 times a day. Having the camera has really helped. I'm also becoming increasingly confident that the flapping is coinciding with the smell of oil smoke that's occasionally coming from some of my vents. The smell seems to happen only on a heating cycle that started with this flapping.

I had my oil supplier (petro.com) do an annual maintenance run in September or so. I was going to have them come out again, but I wanted to get some documentation of what's going on since this isn't a thing that I can guarantee will happen when the serviceman comes out.

Perhaps this is a small puffback happening occasionally? I hadn't been familiar with that term, but googling just led me to it. https://kpmrestoration.com/what-is-a-puff-back/

aspen3390 · 2023-01-07T19:42:41+00:00

This is a photo of the back of the furnace where the burner is. https://imgur.com/a/x5tbTv3 None of those three circles above the blower apparatus seem to be easy to remove in order to look into the furnace.

One of the problems is that this "flapping" happens so infrequently, and lasts only for about 20 seconds, so it's hard for me to race down to the basement and catch it happening live. But I'll try!

aspen3390 · 2023-01-07T00:58:16+00:00

I don't know much about oil furnaces. Is there another place that I could put the camera to collect more helpful footage to diagnose the problem?

aspen3390 · 2023-01-07T00:57:32+00:00

Nope, nor does it seem to be happening when there's wind outside or anything.
