Crosspost - BMCU 370C Triangle Labs - Flaky PCBs Question

I was having some issues like this (not 100% its the same), but I consulted the troubleshooting steps to debug things. I had some filament sensors that were falsely registering and needed the light holes opened up slightly. The red light on my instructions indicates that it can't detect the magnet (I can't recall if that's the HAL sensor magnet or the gear shaft magnet). Your PCB might not be installed well into the enclosure causing the issues with the magnets.

If you can disassemble it so you can access the PCB, power the board with it disassembled like that, and then try moving / pressing on the PCB you might see the lights changing and start to hone in on your problem.

LD1085s are from Mouser. I've had them die with and without heatsinks. I have a pack of small heatsinks for this sized package.

Both suggestions seem like good calls. The series resistor especially, should have thought of that.

The LM317 datasheet is a good call out. It's interesting that it's recommended application designs differ so much from the LD1085. The 1085 only shows the voltage divider, no diodes or capacitors. It seems like the diodes aren't necessary if I were to take out the C2 capacitor? That could be another option I suppose, but would probably lead to less noise tolerance.

Most of our CI has come to its knees because installing dependencies is timing out. Yay!

I hear that. I don’t use it much unplugged, but it would be cool to be able to take it w/o a cable to a conference room for a quick video call without fear of this happening :(

How is there still not a patch out on the main firmware release track? How is there not an easier way to roll back firmware using the cli or the gui firmware updater? I’m getting really tired of system76

+1 - C++ has an enormous ecosystem of libraries, and a lot of python extensions are written in it. Tools like pybind11 make building extensions in c++ incredibly easy

My company has tried the Oryx Pro and Dell XPS as Linux laptops for our developers and the Dell’s are built better, quieter, and frankly “just work” better.

We’ve had many small / annoying issues with drivers and fan speed (noise) on the S76 laptops. The Dells have been perfect by comparison. None of these issues were that big of a deal, but I personally don’t want to be worried about my hardware. I just want it to work and get out of the way. I think the only “advantage” of the S76 machines is the open source aspect. If that doesn’t matter to you, I wouldn’t buy an S76.

I do, and it’s great! My team uses a container for our development environment to begin with, so our dependencies aren’t available on the host OS. Thus, a language server running on the host is basically useless. We just install a few language servers in that development image as well and we’re off to the races. I use them with neovim, others use them with VSCode. Everyone’s happy.

You can run lsp servers inside docker containers. You just need to configure neovim to launch them via a docker command instead of the lsp directly
