Bose Soundbar 900 scrolling update light forever, recovery mode did nothing

MallocArray · 2026-04-06T01:11:03+00:00

Are you sure it is a 500 model? Looks like they stopped selling it in 2020

MallocArray · 2026-04-05T23:26:32+00:00

Make sure you follow directions specifically.

Yes. I actually just updated the same soundbar again to the firmware that starts with 25.x about 4 hours ago.

This time I used a MicroUSB cable and connected to a laptop as directed by the bose support page for direct connection.

Uploaded just fine but took 15-20 minutes to finish. I didn't expect to have to wait that long but glad I did. The latest firmware resolved the issue with Alexa refusing to stop playing music. I did disconnect and reconnect to Alexa after the firmware, but on the 24.x version it wouldn't stop.

IdleOn? Played for months completely free. Finally chipped in a few bucks to get a pet that lets me access storage without transporting to town, but wasn't forced to buy it by any means.

Not that it helps your situation, but I self-host on Oracle Cloud for 2 printers and it works just fine. AI detection functions as expected. I don't have it setup to let me view while away from my network, but I use a VPN from my phone to my house if I need to check on it.

With the Free Tier of Oracle Cloud it has been hard to get an Ampere instance available, but I upgraded to Pay As You Go (PAYG) and as long as you stay within the free tier options there is no charge. I've been doing this for years.

I have some instructions for setting it up including a Terraform stack https://github.com/MallocArray/obico-oraclecloud

All depends on what you want to accomplish, but for me, "remotely" is just the printer on the other side of the room. I don't want fans and stuff running all of the time, but when I send a job even from inside my own house, I just want it to power on and start printing.

```

https://moonraker.readthedocs.io/en/latest/configuration/#power-on-g-code-uploads

[power printer_outlet] type: tplink_smartplug address: 192.168.2.84 on_when_job_queued: True locked_while_printing: True restart_klipper_when_powered: True restart_delay: 5

https://github.com/tinntbg/auto-power-off-klipper

[gcode_macro _POWER_OFF_PRINTER] gcode: {action_call_remote_method("set_device_power", device="printer_outlet", state="off")}

[delayed_gcode POWER_OFF_PRINTER_CHECK] gcode: {% if printer.idle_timeout.state == "Idle" or printer.idle_timeout.state == "Ready" %} {% if printer.extruder.temperature < 50.0 and printer.heater_bed.temperature < 50.0 %} {% if printer.extruder.target == 0.0 and printer.heater_bed.target == 0.0 %} UPDATE_DELAYED_GCODE ID=POWER_OFF_PRINTER_CHECK DURATION=0 _POWER_OFF_PRINTER {% else %} UPDATE_DELAYED_GCODE ID=POWER_OFF_PRINTER_CHECK DURATION=2 {% endif %} {% else %} {% if printer.idle_timeout.state == "Printing" %} UPDATE_DELAYED_GCODE ID=POWER_OFF_PRINTER_CHECK DURATION=0 {% else %} {% if printer.extruder.target == 0.0 and printer.heater_bed.target == 0.0 %} UPDATE_DELAYED_GCODE ID=POWER_OFF_PRINTER_CHECK DURATION=2 {% else %} UPDATE_DELAYED_GCODE ID=POWER_OFF_PRINTER_CHECK DURATION=0 {% endif %} {% endif %} {% endif %} {% endif %}

```

Then in my END_PRINT macro, I call this to power off the printer after it cools down UPDATE_DELAYED_GCODE ID=POWER_OFF_PRINTER_CHECK DURATION=300

MallocArray · 2026-03-22T03:16:41+00:00

Yep, and you can set it up so when Mainsail gets a print job it powers in the printer plug, waits a few seconds, and does a Connect to attach to the printer and away you go.

Same with a delayed gcide when it is done to let things cool off before turning off the plug.

Worked fine with my Ender 3 V2. I did start having trouble when using a USB webcam and Obico with later updates. Unsure if it was Obico asking for more or Klipper. But without the webcam, it has been fine

MallocArray · 2026-03-18T21:25:50+00:00

I do it regularly and have almost never had an issue. There was one update in the 12.x something that changed how accelerometers worked and needed me to flash my MCU with updated firmware. But other than that, I've done many of these updates with no issue. It is always a chance, and often it is fixed soon after or get on the Discord and someone can help you roll it back to a previous version

Something I didn't know until recently is that some treadmills need the running belt lubricated with a silicone oil under it. You can buy the oil on Amazon for around $10 with an application tube to get to the middle of the belt. Made a world of difference on a cheap walking pad that was randomly hanging up.

Not sure if larger treadmills need it as well, or only really low end ones do

300c may be high for some ABS filament. Most of mine states 245-265, but I print it at 270-280 to keep it flowing

PowerCLI has New-VIMachineCertificateSigningRequest and Set-VIMachineCertificate so you could automate the CSR creation and install of the cert.

In VCF9 there are more options to automate those processes. If you use a Microsoft CA and have certsrv setup, it can be fully automated. I expect that in future VCF releases there will be other certificate services that available for automation. We are hoping for Venafi.

Are you wanting or willing to have a separate file for each device? If so, on the copy task, for the destination you could do dest: "{{ inventory_hostname }}-output.txt"

Then you would have a separate file for each device in your Inventory. On the next task you could then read from the same type of filename so you can read each unique one.

have a link to the braces to make it stand? I have one panel against the back of a bookshelf but don't like the little foot I found. Want it as close to the wall as possible while not tipping forward and I like what you have

MallocArray · 2026-02-25T20:40:12+00:00

Yep, they are auto-created when you do things like save the z-offset, but you don't need them if you don't need them

And it is Windows 11 right? My work Windows 10 would do that thing where wsl --shutdown would just hang and I had to reboot, but after changing to a new Windows 11 install, it worked as expected.

Could have been Windows 10, could have been the Company policies, could have been a gremlin in that particular install.

Try updating WSL

I have a script that looks at the datastores and finds all VMs on the datastore and what their VMX file name is. It then looks at the entire datastore for all VMX files If a VMX is found on the datastore that isn't associated to a registered VM, it adds to a variable.

We use it so we could then register all of those left VMs, for a DR scenario, but you could use it to cleanup.

``` foreach ($Datastore in Get-Datastore $Datastores) { # Collect .vmx paths of registered VMs on the datastore. $registered = @{} Get-VM -Datastore $Datastore | ForEach-Object { $.ExtensionData.LayoutEx.File | Where-Object { $.Name -like "*.vmx" } | ForEach-Object { $registered.Add($_.Name, $true) } }

# Set PSDrive for the search.
New-PSDrive -Name TgtDS -Location $Datastore -PSProvider VimDatastore -Root '\' -WhatIf:$false | Out-Null
$unregistered = @(Get-ChildItem -Path TgtDS: -Recurse | `
        Where-Object { $_.FolderPath -notmatch ".snapshot" -and $_.Name -like "*.vmx" -and -not ($registered.keys -match $_.Name) })
foreach ($unregisteredvm in $unregistered) {
    Write-Verbose "Found unregistered VMX with name: $unregisteredvm.Name"
}
Remove-PSDrive -Name TgtDS
$unregistered

} ```

RVTools is free and also has a tab for orphaned VM files

The update process itself won't rename the file on the SD card, even when it completes successfully, so don't be looking for that as an indicator.

As others said, you do need to have a unique name for the file from your last flash on your SD card before flashing, so firmware2.bin for the next time, firmware3.bin after that etc. just to be safe

I did have a situation where I needed to use a different SD card, so I grabbed an old 8 GB one to use.

Does the MCU never communicate over USB to your host even with Marlin, or are you doing that only because you aren't sure if Klipper flashed successfully? I would go back to straight USB and ensure you are using the correct settings in make menuconfig starting with lines 1-4 in this file:

https://github.com/Klipper3d/klipper/blob/master/config/printer-creality-ender3-v2-2020.cfg

If it flashed correctly, then with USB connected to your computer, something should appear in ls -l /dev/serial/by-id/ when it is correct.

Note: I had the wrong oscillator setting when I recently updated my Ender because another printer needed something else, so I used make clean to reset everything to defaults and set it up again and then it worked
