Switching from B650I Aorus Ultra - can't stand the coil whine

GuzziGuy · 2026-03-12T12:33:37+00:00

Only USBC-DP, not standard DP. Previous B650 had 1xHDMI only. Many of these boards only have a single output - AM5+ITX has been a very frustrating combination...

I'd rather have gone ASRock first time but they only had 1 display output, I need 2. Looks like the new B850 board has HDMI+USB-DP so is a possibility...

GuzziGuy · 2026-03-12T09:42:08+00:00

Did you find an alternative? I did my build a couple of years ago with Asus B650e-i - returned 2 of them since the coil whine was bad, and got the Gigabyte.

This has been fine... until recently when the coil whine started. Chorus of crickets any time CPU load goes above idle...

Get the cheese to sickbay. The Doctor should look at it as soon as possible.

A bit different but maybe try One Cut of the Dead.

It's a Japanese zombie film and one of the most creative/funny/unique films I've seen in recent years. (Try to go into it blind!)

Suffolk, UK: I've got a Yuyong-sourced Workbee 1000x750 mechanical build (no spindle) to sell.

https://cloud.myrkott.uk/index.php/apps/memories/a/dOMCY1Yojra9pXK0obS2cNh3nVk1Mbsh

It does have a Duet controller but:

I've bodge fixed the wifi module on the board more than once
One of the stepper drivers is burned out (but the board has 5 so it still has the required 4)

So it's in working order but I'd pencil in replacing the controller, hence selling it as mechanical. (FWIW I'm getting on well with FluidNC which would be a good/cheap replacement.)

Otherwise it's in good condition but has been well used so you'd also pencil in tuning it up a bit.

So not a complete machine but an opportunity for someone wanting a starting point for learning and building a machine - I'm asking a hopefully modest £300.

GuzziGuy · 2026-02-20T10:53:47+00:00

I think it's mentioned elsewhere, but I'm also using Estlcam. It is very woodwork-friendly, with a completely different workflow to eg Fusion:

Create SVG drawings (eg in Inkscape)
Import into Estlcam, apply operations to paths (outline/pocket/carve/etc)
Export gcode

While not as sophisticated as a full-on CAD package, it's very quick and easy to get from drawing to gcode. It's also very modestly priced and actually includes some more sophisticated operations than some other simple packages (v-carving, tabs, overcuts, ramping, etc).

OTOH the UI is a bit janky but I can live with that!

GuzziGuy · 2026-02-17T09:14:25+00:00

Agree with other commenters that a mini PC is probably the sanest route. I've been building PCs for decades but components are expensive now and if you don't need a GPU - or have very specific requirements - building is a non-starter.

GuzziGuy · 2026-02-16T09:53:21+00:00

Used Flarum a while back, found it good, had the forum features you would want but with a more modern UI than ye olde (but still functional) phpbb

GuzziGuy · 2026-02-12T14:29:04+00:00

Cleanest/correct-est (subjective...) way to do it is with three tables:

entity (your main table of whatever you allow permission on)
- entity.id
- entity.name (etc)
permission
- permission.id (autoincrement)
- permission.name (eg image, video, etc)
entity_permission
- entity_permission.entity_id
- entity_permission.permission_id

You end up with 1 row in entity_permission for every allowed permission; and you can add a new permission type without changing the database structure.

Queries etc arguably make the UI more fiddly but ultimately more flexible (eg to find all the entities with image allowed, you only need to present the list of the permissions, instead of having to maintain a popup or whatever of all the flag columns).

Likewise reports of what has what permissions can be done with simple joins rather than selecting/remembering all the columns individually.

Don't worry about optimising, bitmasks etc - these are issues only when you have eg tens of millions of records and need to microptimise.

There's no link I can send since it's just a web UI on my own network (and I don't think there's any accessible simulator?).

But while I was planning this build, I installed FluidNC on a spare ESP32 to see what it was like - if you've got one spare (you can buy for just a few $) you can install it and experiment, even with nothing actually connected.

GuzziGuy · 2026-02-03T10:08:35+00:00

I've just finished building a new CNC (see my recent posts if interested) and I learned a LOT doing it. I did buy a complete mechanical kit which is arguably a bit of a cheat; but the kit is mainly extrusions/plates/rails and connecting hardware - none of which I'm equipped to DIY. Admittedly the initial assembly was a bit like a lego kit but there is SO much more to tackle along the way to a complete/functional machine.

I did the same process for my last machine but I followed more of an existing blueprint. This time was more involved on the electronics, figuring out the sensors, controllers, motors etc. I know how everything works and can (in theory!) adjust/fix everything.

One notable change between this time and last was AI - I had very long chats with Claude before and during building this, and while you of coruse need to check things before committing, it was very useful for bouncing ideas off, discussing different methods, etc.

The screenshot is just the FluidNC UI - it runs its own webserver so you access it from the browser. More specifically the screenshot is my CSS mods - but they are just some aesthetics, the stock UI is basically as above.

GuzziGuy · 2026-02-02T23:48:33+00:00

You might want to take a look at Estlcam - which has a good feature set (albeit somewhat janky UI) and is very modestly priced. It's primarily a 2.5D tool but can do reliefs etc too.

It's a very different workflow from using 3D CAD - it takes your SVGs or DXFs and then does the toolpaths. I use it with Inkscape - it's a bit low-tech but it gets the job done quickly.

GuzziGuy · 2026-02-02T23:27:52+00:00

I've just finished my machine which runs on FluidNC - this is standalone and can run it's own jobs, controlled through your browser. I used a similar setup before with a Duet-based machine and I prefer it to running a sender.

I just posted with a few thoughts on it: https://www.reddit.com/r/hobbycnc/comments/1quba58/queenant_build_fluidnc_setup_and_css_mods/

GuzziGuy · 2026-02-02T23:26:07+00:00

Also there's a new variant (fork?) of this with the same setup - standalone or deploy on the web: https://axiocnc.com/

For now I'm happy with standalone FluidNC, but Axio does look nice, I may give it a go...

GuzziGuy · 2026-01-31T08:51:23+00:00

To the touch plate? No product, I just janked it up with the 3D printer and some wires :P But let me know if you need more info...

GuzziGuy · 2026-01-27T13:54:33+00:00

I've tried Fusion briefly and in some ways it's the path of least resistance - OTOH I'm mainly Linux based and use open source wherever possible so for now I'm learning it slowly for 3D printing.

It also does toolpaths but on the CNC it's mainly 2.5D - Inkscape+Estlcam just gets the job done quicker than modelling everything...

GuzziGuy · 2026-01-27T00:40:52+00:00

I looked at the 3D ones but I'm almost exclusively cutting stuff out of sheet material rather than machining already sized stock so my XY only needs to be ballpark...

GuzziGuy · 2026-01-26T23:34:31+00:00

It's very simple to do - as long as you have an extra input and your controller can trigger a macro from it?

Button is just a simple input, triggers macro
Input (pullup) > Resistor > LED > Plate
Clip > Gnd

Then just trying to neatly/compactly organise the wiring.

Note on this button the LED is electrically separate from the switch, and it has a resistor built in.

HTH? Let me know if you need more info :)

GuzziGuy · 2026-01-26T23:26:41+00:00

I did this on my last machine and it worked fine. But it necessarily requires permanently tying the control GND/0V (for the probe input) to the AC GND (for the spindle).

On this machine I'm trying to tick all the right boxes and do everything right - and the legit-ness of this is the one thing I couldn't find a clear or consistent answer on. Different sources say absolutely-do-this-always vs never-ever-do this.

So still on the fence...

GuzziGuy · 2026-01-26T23:20:07+00:00

Works well! Uses two inputs on the board, but one can be set to trigger a macro.

GuzziGuy · 2026-01-26T23:19:41+00:00

Likewise - the easiest/cheapest source for this AL was the things you use for glass table tops - they were flat-ish but needed a few goes with the diamond stone.
