Hi

A couple of days ago the hotend wouldn’t heat up and i got a couple of errorcodes/warnings in the display. The bed heats up just fine, so i ordered a new hotend parts (heater, thermistor and a new aluminum block). Changed all of this, but still the same error. I can se that the thermistor works because it changes values in the display when touching the thermistor-end. Any good ideas why the heater doesn’t heat?

    I can se that the thermistor works because it changes values in the display when touching the thermistor-end.

    Good information. You can probably remove thermistor from possible cause, but to be sure, you can tape the thermistor to your heat bed, and heat to a high temp, make sure that the “nozzle” temp is close to the bed temp

    What is the behavior when you hear the nozzle? Does it immediately give error, or does it take some time? If it takes some time, is the temp changing on the nozzle at all, or it stays the same until error?

      When starting the preheat both the bed and the nozzle temperature starts at about 25c. There is no heating at all. The printer takes about 10-15 sec to conclude with the error message.

    Welcome to Biqu B1 world. Where nothing makes sense and you’ll never be able to get a nice print.

    Mine came with the same issue and nothing solved it. It’s literally a piece of trash in my room. Saving for a Bambu. btw I have a Elegoo for years and it’s perfecr

      out of curiosity, why would you not have gone with an Ender 3 over this non-brand thing? Or if you have Bambu money, that or another quality brand? It sounds like a recipe for pain and it’s not cheaper than the super well (community) supported Enders.

        I’m a totally noob in the 3D printing scene. My brother has a Biqu B1 and I’ve printed some small things on his printer. Found a used Biqu B1 for sale for about $80. Yeah, not good research from my side… But, I’ve printed a well printed fucktopus before it died…

          $80 makes it reasonable. At normal MSRP… Ender.

          Good luck and make upgrades slowly and as needed.

        Because I’m dumb. I don’t have bambu money and a couple of years ago I didn’t even knew about it. I read somewhere that biqu b1 was better and had less problems than the Ender and was noob enough to fall for it. I’m used to resin printer so I didn’t knew enough about fdm and just went with biqu. Horrible decision

          It’s not easy trying to research which 3d printer to buy, there is more click bait and marketing than impartial reviews out there, and search engines tend to promote the garbage. And without a lot of 3d printing experience, it can be difficult to know if a “review” is paid for by the printer’s manufacturer, or just trying to trick you into clicking their affiliate links. There are also no consistently good brands if you’re looking for a cheap printer, pretty much all of them have produced a few good printers and others that have more flaws. For example old Ender 3 and Ender 3 Pro were very good at the time, and Creality built up a lot of brand recognition, but then they switched to low quality components and seemingly stopped doing quality control and made a bunch of crap. Now it might be turning around again, as Creality’s latest printers are starting to look decent again, although perhaps a little overpriced.

          Personally I use this spreadsheet to compare pros and cons of budget printers. It’s maintained by a group of users at a 3d printing discord server, and while one cannot know for sure none of them have any ties for example to Sovol (the most recommended budget brand currently), they’ve seemed quite impartial to me so far.

      That sucks. I have no clue about 3D printers and did no research before buying this one used. Worked OK for about 6 days… Well 80 bucks…

        You can get a new board for <$50 (you don’t need the same board that’s in the printer), spend an hour or two learning how to move the cables from the old to the new, and still have a pretty good deal

          I would 100% buy replacement parts IF i knew how to replace them, but to be honestbif I try I’ll probably end up with a bunch of scrap. At peast the trash print some ugly things

            Nahh, just take parts out and lay every part side by side, and just put them back in reverse order… And, take some pictures underway of where all the connectors are connected. You can do this. Hell. i don’t know what I’m doing and I’m gonna at least try…

    Make sure the wires to the hot end actually trace back into the main board. And the mosfet is fine.
