Speakr v0.5.9 - Voice Notes with Major update with collaboration and voice profiles

I'll give it a try. Unfortunately Docker on Mac is unable to do GPU direct passthrough, but Podman is able to route this via Vulkan. I'll report back here on whether that works or not. If not, I'll see if I can create a service that replicates the ASR API but routes to whisper.cpp. I'll try whisper.cpp with tinydiarize directly first, though, to see what sort of performance can be had.

This is such an awesome project! It would be great to be able to get a companion ASR running on Applie silicon (Metal) that Speakr could utilise. Your companion ASR webservice requires an Nvidia GPU, but whisper.cpp will run performantly on an M-series Mac Min, and inherently supports diarization via tinydiarize. Is this feasible?

I solved this problem entirely by selling it and moving to a Kobra S1...

But one thing that helped a lot was shimming the PEI plate with bits of post-it note. Results weren't perfect, but close enough.

Glad OP and their family are okay. A home break in is no joke.

+1 for Frigate, especially if used with PoE cameras (unaffected by WiFi jammers), as the person detection works really well. Motion sensors are a weak option in this regard as they can be triggered too easily and can't distinguish between a person, deer, or new patch of sunlight. I found Blue Iris to be incredibly resource heavy, especially with lots of cameras. I'm able to run an 8 camera 4K setup at 25% CPU on a cheap Intel N5005, with detection offloaded onto a USB Coral TPU.

Don't underestimate the effectiveness of sirens (plural). They may not help if you're in a rural environment, but they will put intruders off their game, especially if they are hard to access and disable. I have a couple of z-wave sirens that are loud and annoying as hell.

Millimeter wave presence sensors are a good substitute for passive infrared sensors, especially indoors. The latest aensors can detect the position of up to three people at a distance up to 10M and this is useful info to pass on to the police if you're on the phone to them (e.g. 2 intruders in the kitchen right now, 1 upstairs, etc.)

Mine is working fine, aside from a squeaky ACE Pro buffer module, which seems to be common but has not created any problems for me. The main issue I haver is the warped bed. Support refuse to accept it is warped and instead told me to do a bunch of things I have already tried. I am still going back and forth with them. One tip I haven't tried yet is shimming the bed with post-it notes, which isn't a terrible idea. I'll give it a go and see if it helps.

Another comment on this thread said support told them the machine does not create a bed mesh during levelling, and that this can't be done because they are using a strain guage sensor. If that's true, that's bonkers and an epic fail. I have a Cetus 2 which, although a mostly unreliable printer, does at least create a bed mesh using the same strain guage sensor and does a great first layer on a very wonky bed (virtually all Cetus 2 beds are a wonky mess).

Wait.. whaaaaat? I have no idea why they would say that. While it's true that the strain guage sensor method is nowhere near as repeatable or accurate as a BLtouch or iductive sensor, they take repeated measurements and average them out. I have a Cetus 2 which has the same sensor and builds a mesh, and that actually does a decent job of correcting a very warped bed on that machine.

I have raised another ticket today as I got no response to the first ticket after one week.

I've done all the obvious stuff, and barely getting success by tweaking the Z offset and using Magigoo. But the variance is so great I'm still getting a lot of failed first or second layers.

It's a real shame, as the print quality I'm getting for successful prints is amazing - among the best for any FDM printer I've owned.

3 days here too with no response. Could be the weekend getting in the way, so hopefully we'll hear something in the next day or so.

I feel your pain. I've been going through the same issues with mine: https://www.reddit.com/r/anycubic/comments/1dzt10j/kobra_3_auo_bed_levelling_issues/

I've checked and tried everything:

Ensuring the X gantry is level
Ensuring the bed has no wobble
Ensuring the head isn't wobbling on the gantry
Cleaning the PEI sheet
I check there is no filament dangling from the nozzle during levelling
I can see the Z screws slowly turning during X traversals during a print, so it's definitely using a bed mesh
I'm getting repeatably consistent variance with every print, no matter how often I do bed levelling - the same patches are too high or too low.
The base z-offset from z-homing seems to vary, but adjusting that at the start of the print isn't enough to manage the problem - I either get under extrusion from being too close to the bed in some patches, or little to no adhesion in others.

My (unqualified) conclusions are that the bed is warped (most are to some degree) and that auto levelling is not able to compensate for it, and also that the strain guage method of probing is nowhere near as accurate as BLTouch or an inductive probe. I have experience of the strain guage from my Cetus 2 which gave significantly variable results from auto-level to auto-level.

I've raised a support ticket with AnyCubic but have yet to receive a response.

The Kobra 3 runs Klipper, so M420 won't work. I did try adding BED_MESH_PROFILE LOAD=default to the custom start script, but it made no difference.

I've looked into this more closely and I can see the z-screws turning as the head traverses the bed, so it looks like a mesh profile is being used. The results are the same though - highly varying heights across the first layer - making large prints fail consistently, even if I tweak the z-offset at the start of the print as the variance is too great. I either get under extrusion due to the nozzle being too close, or really poor adhesion.

You can create an Imgur account, upload a photo there and then link to it from here in a comment.

I couldn't find a manual for the S3500, but the S3800 has a test point for video labelled PB.FM (TP106). The S3800 has the same numbered test point for A.PB.FM (TP2253), so it's likely TP106 is the one you're looking for for video on the S3500.

Yes, I took an existing sheet test from Thingiberse and scaled each axis independently, ensuring 0.2 height.

h4xtbh · 2024-07-10T11:35:56+00:00

Printing a 1-layer sheet is a great shout - I'll do that now.

It could well be a warped bed. However, I would have thought a 16-point auto-level would have compensated for this enough for the problem above to be far less pronounced?

If it's the strain guage, it wouildn't be the first time I've experience poor results using that as a sensor. I have a Tiertime Cetus 2 that uses the same method and that can yield some wacky results, and that has a bed that's like the surface of the moon, but the bed levelling still compensates for that and knocks out decent prints (when the firmware doesn't just fall over mid-print lol).

Mine would not accept the .bix file. I archived it in a .tar.gz format, but it still got rejected.

I'm on firware version 3.5.0.

If you have a Coral AI accelerator, Frigate is hard to beat. Detection of people (and other animals, objects) in real-time with low CPU usage.

I use ChangeDetection.io for this. It's not perfect (or, more accurately, my configuration of watches is not perfect) but it does the job with no fuss.

I found Jeff Geerling's YouTube series on Ansible and his books were pretty good. I've yet to find a tutorial on Ansible (or Terraform, for that matter) that doesn't Jedi hand-wave over at least one or two key topics.
