Alternative Printer Uses
  • Is that a motorola moto z2 play? I owned that phone and I used to disassemble it just like this!

    Edit: saw in another comment that it's a z4. The camera did look strange for a z2 at a second glance

  • I wonder how it affected traffic
  • While I don't remember his name, I remember there was a Darknet Diaries episode about the researcher who first investigated the problem. The episode was very thorough, I liked it a lot. I also don't remember the name of the episode, so I guess this comment is kinda useless

  • [Followup] Still working on that damn clogging issue!
  • Hello, I suggested heat creep in your last post, which didn't end up being the issue. I don't remember if anyone suggested it, but have you tried checking the bowden assembly, on the motor side? Whether the stepper works, or the gears wore down (I'm pointing towards this), or there are clogs somewhere in the mechanism, even some dust that accumulated where it shouldn't had. Or did you change settings like the current limit on the steppers? If that's controlled with a potentiometer on the main board, maybe it got turned down for some reason (if so, I'd try to understand why's that). I don't know how Klipper handles motor drivers where current limits are controlled in software, I know that Marlin has a dedicated submenu in the Configuration>Advanced Configuration. If you reflashed the firmware, maybe the settings where in the eeprom and did not get transfered over or got overwritten in the flashing process.

    I remembered that on a couple different printers I had the same problem as you, and it came down to damaged/untightened nozzles (which you excluded already) or wore down gears or, on the printer I'm working on right now, too low current limits which made the stepper skip steps somewhat randomly

  • [Troubleshooting] Cannot fix a clogging issue.
  • Since you've already excluded a damaged nozzle and other parts, I'm gonna suggest heatcreep.

    Maybe the extruder fan broke, so heat creeping up the extruder and melting the filament before it should?

  • Paying for mullvad via mailed cash
  • I did that some time ago. I just put the letter in an envelope, with just the receiver address on it, went to my local post office, paid for the service and the stamps, left them the letter and I was done.

  • Lines through printed pages
  • Also depending on the architecture on the computer, this might be the only possible solution. I have a samsung m2020 series printer connected to a Pi to share it on the local network. Samsung Unified Driver does not work on armhf as it is only compiled for x86/x64, but splix can be compiled on armhf and it actually supports my printer

  • Using an nVidia Tesla p40 for rendering on Linux
  • What did you do to keep the card cool?

    Poorly. Had 3d printer a fan duct and ducted a fan to the back of the case, to push-pull air. Those cards are made to work in server racks, with really high pressure and high speed fans, not really for a desktop. I have seen people on reddit mounting a modified 3070ti cooler on the tesla, but I had not had a chanve to try that.

    And was it loud?

    Yes, depending on the fans used. But high speed fans are generally loud. Also lots of vibrations, but that qas mostly fault of my incredibly sketchy setup

  • Using an nVidia Tesla p40 for rendering on Linux
  • I used to do this with a nvidia tesla m40 and a radeon hd6850. Used the tesla for rendering amd encoding, the radeon for display output. I just followed the arch wiki pages related to nvidia optimus laptops and PRIME offloading. It worked but was a bit junk, in some other tests I did, when the radeon was used to render the DE, I had a much more fluid experience, offloading the rendering seems to lead to some micro stutters every now and then that make it a not so fluid experience. But ymmv I guess. Also I haven't had any luck with two separate nvidia cards, but that was probably due to driver version mismatch between the two cards

    [Advice Request]: managing thermal pads for SMD components in custom PCB

    Hello everyone, I need some advice.

    I am making custom PCBs for a project of mine. It's basically for a little remotely controlled robot using little DC motors. I chose the Seeed Studio XIAO ESP32C3 as the uC since it has inbuilt wifi/bt, 3.3V regulator that I can use to power the motors (can source up to 700mA) and lipo charging management (the robots will run on battery). As you can see from here, the microcontroller is surface mounted and the pads for the battery are on the bottom layer. Same story goes for the thermal pad of the microcontroller and the thermal pad of the motor driver (datasheet). I have worked with SMD components in the past and can solder them by hand, but I have never worked with SMD components that have thermal pads on the bottom layer. My question is: how to manage (route?) them? My PCB is 2-layer and I was planning on having both layers filled with a ground plane. Do I just connect thermal pads to the ground plane and call it a day? Wouldn't that make the components hard to solder with hot air? Do I make an isolated polygon that only acts as a thermal pad?

    Speaking of soldering is even hot air the way to go in this case? My PCB has components on both sides, and I was planning on ordering stencils together with the boards and using solder paste, placing the components and then using hot air to solder the components in place. I thought a hot plate would be better but I don't have access to one and I don't know how that works with components on both sides.

    I attached some photos of the PCB in Kicad, and here's the git repo. If it is of any help, I'm planning of having them manifactured by JLCPCB. It is also my first time using KiCad, so go easy on me :)

    Thanks!
