  • It’s absolutely the best place to buy stuff like this. I buy spools of addressable LEDs, ESP boards, random electronic components, and smart home stuff from there provided I can wait a week or two to get it. You’re buying the exact same stuff from Amazon most of the time but at much cheaper prices with longer shipping times.

    That said, I probably wouldn’t ever buy a branded product like OP did because if they screw you over it’s going to be a huge pain to try to get a refund and there’s a decent chance it’s not as described or straight up counterfeit.



  • The P1S/P1P would definitely be worth it over the A1 mini as the CoreXY construction is a complete game changer. I don’t think I’ll ever buy another bed slinger printer. The whole design just doesn’t make sense outside of being economical, which was fantastic 5+ years ago in order to get everyone into the hobby, but is really limiting now.

    Bambu has really changed the landscape and elevated the hobby as a whole, which will be awesome for everyone once some competitors start trying to copy what they’ve done.


  • Most will work right out of the box (after assembly) but the cheaper printers like the Ender will require periodic tinkering and upgrades to keep it working and make it perform better. I just retired my Artillery Sidewinder X2 (which is similar to the Ender CR10) for the Bambu X1C and don’t regret it one bit. Prints just work all the time now and I haven’t had to tinker with anything. My X2 has been upgraded quite a bit and yet still frequently gave me (solvable) issues that would be so frustrating when I just wanted to get something printed out.

    I would also recommend the A1 mini if you’re not looking to tinker and can deal with the bed size. Bambu Labs has done a great job on their lineup, MakerWorld, and by offering filament as well. They’ve really simplified the whole process.


  • How does this make any business sense from any angle?

    Presumably, you have the actual file already, but you can’t give some free advertising to the creator by posting a make of the file? Locking the file behind a paywall makes sense since that’s the actual thing of value here. Locking a make behind a paywall is neutral for the consumer and a negative for the creator.

    From the consumers’ perspective, there is essentially zero incentive to pay just to post a picture of someone else’s creation. There’s no FOMO, there’s nothing being ‘withheld.’ It’s just one less step you have to do (assuming you wanted to do it in the first place).

    So what happens here is the creator loses out on free advertising, the consumer isn’t even mildly inconvenienced, and Prusa still gets zero revenue out of the whole deal.

    Can someone give a rationale for this? Maybe something I’m missing?







  • One thing you’re overlooking here is the connection between the hot end and the control board. Perhaps a ribbon cable has gone bad and one of the wires inside is on the verge of snapping completely in two? This would cause inaccurate, high resistance values giving you a lower nozzle temperature as well as give you intermittent and worsening issues. You could just swap it out or use a multimeter to check the resistance from one end of the ribbon cable to the other.

    Frankly I’m impressed you’ve managed to troubleshoot this far. Just normal/common printer issues often cause me to step away from printing for months at a time due to the frustration.



  • I don’t know a ton about their design, so I could be wrong, but I believe with Trinamic drivers, they typically have current limits set in the firmware that will cut power if they exceed the limit. It could be jamming and just naturally springing backward as it occurs and power is cut.

    Rotating by hand, you’ll feel the magnets inside giving some natural resistance (like you’re hitting notches) but it should be consistent and smooth otherwise. If you feel any extra resistance at any point in the rotation, I’d just swap it out or disassemble it and look for debris like plastic shavings.


  • Take out the extruder stepper and rotate the shaft by hand and feel if there is binding at any point. I think I mentioned I had this same issue on my direct drive printer in your previous post. It would work fine until it didn’t and randomly act like the nozzle was clogged. When printing, I think the load on the motor is going to be greater than feeding filament through into open air, which may exacerbate the problem.

    You’ve xhecked the hotend a bunch of times so I would focus on other areas. Something else may have broken at the same time as your nozzle swap which may just be leading you on a wild goose chase.


  • Have you checked the health of the extruder stepper motor and really examined the filament path? I’ve had two weird issues with my direct drive extruder, one was the filament had work a small groove into the metallic tension arm which would catch the filament and cause it to jam. The other issue was a stepper motor that got some debris in it and would bind up intermittently. Not sure if your printer has a bowden setup, but it’s something new to check out.





  • Maybe I’m missing some context here, but ‘debouncing’ is just accounting for the fact that every switch, when pressed, will bounce on and off the contact for a few milliseconds. If you didn’t account for this, then turning your light on would cause it to flicker on and off rapidly until the switch settles.

    Your zigbee devices phoning home all day while not being used shouldn’t have anything to do with debouncing.
