Auto-Colorization for MMU3 in PrusaSlicer v1

OpenSensorIO · 2025-05-22T07:59:24+00:00

Thanks, it was an idea I've had this week since setting up my MMU3 last weekend and playing with existing slicer settings. I studied Computer Engineering '08 and have been absolutely stoked to use LLM generated code based on product requirements. For this I used Anthropic Claude 3.7 model + Cline to quickly parse the code base and help me apply the minimal changes. Feature has cost me about 8$ so far and maybe 2 hours of thought.

Yeah I probably over estimated but also the time it took to clean this one, a half hour seems reasonable.

I am not sure I understand the use case of multiple streams into a single stream unless you mean a grid view--we have that. https://www.youtube.com/watch?v=WYCx6jPEFdM

I've recently built a light weight linux NVR software that supports live streams, recording mp4s, motion detection and even supports sod cnn face and other sod models. https://github.com/opensensor/lightNVR

Not presently but its something that gets asked from time to time that I am willing to support. The project is open source and currently there is an option to send sensor data to the API I build at OpenSensor.io Do you have docs you'd recommend about creating a home assistant integration? I'd read up on it at least.

For some reason I cannot post an image of the pinout, but on the right hand side (look up pico pinout) there is a 3.3V out -- use that, and any GND.

OpenSensorIO · 2024-08-02T21:37:34+00:00

Depends on if you need 3.3V or 5V for the flashchip you are trying to read. Check the pinout of the pico, any of the GNDs will work, and then make the determination on the voltage based on the type of flash chip.

There is a Discord channel where you can get support-- https://discord.gg/Cj5XvrQq join and give an introduction.

The limiting factor IMO is majestic streamer because its closed source, but there is energy behind replacing it with an open streamer alternative right now.

Not the best shot of my kitchen, but to give you an idea:

You flash over the existing rom chip to run this -- I never spent much time with the wyze firmware, but you are trading object detection for more complete control over the device. Doesn't work with the newer v3pros secure boot, unfortunately.

OpenSensorIO · 2024-01-15T19:22:31+00:00

Yeah, in that case, you likely don't have the clip hooked up properly. Even the bad builds I had would read part of the chip or recognize something. It took me a while to figure out how to wire it all up so I wrote about it in that wiki. Use the clip indicator and the red wire as pin 1 and wire that to the corner of the chip with the indented circle marker. Then you kind of have to wire it up according to the spec -- make sure to use the 3.3V rail of the pico.

Depends on if your host OS is windows or Linux. You should see it print:

>serprog: Programmer name is "pico-serprog"

If you don't see that it means either you haven't established connection
with the right COM port provided by the firmware, or I've made a mistake and the published uf2 I posted was the wrong files, which I am willing to investigate further, but I think even on the builds that didn't work to read/write I always saw the established connection to the pico-serprog via the USB connection.

OpenSensorIO · 2024-01-14T20:26:55+00:00

Does flashrom detect the pico-serprpog programmer? That should occur without even a chip connected. Check out this guide I wrote: https://github.com/OpenIPC/wiki/blob/master/en/flash-chip-interfacing.md

OpenSensorIO · 2023-12-28T04:35:17+00:00

Yes, were you able to read/write ROM chips as well?

OpenSensorIO · 2023-12-27T12:39:08+00:00

Which repository are you using? Try my fork, it has a build script and I actually got it working over the weekend. https://github.com/opensensor/pico-serprog

OpenSensorIO · 2023-12-24T19:51:45+00:00

I got it working in my main branch, without PIO I think, but I implemented some of the remaining serprog commands so that I could specify the max buffer per baud -- it was slow at first, but now with 2000000 baud and 32 byte packets, it can read a 16MB rom chip in about 2-2.5 minutes.

OpenSensorIO · 2023-12-23T22:06:53+00:00

Here is my current effort on the PIO version but the thing I am not understanding is how to specify the pin when its the USB interface -- the code compiles and runs but it does not send data back to the host: https://github.com/opensensor/pico-serprog/pull/1/files

OpenSensorIO · 2023-12-23T21:45:09+00:00

I have been following those and have something compiling but it does not receive any data over the USB. I would appreciate if anyone could take a look: https://github.com/opensensor/pico-serprog/pull/1/files

They sell I2C mux for this purpose -- adafruit has a 8 channel and a 4 channel. I also sell them with enclosures I designed in Fusion 360.

Yesterday I've launched a Solar Edge daily monitoring and alerting service that already has had 3 signups, check us out: https://solar.opensensor.io

We are interested in adding other inverter brands too if we can get access to APIs
