  • I was tightening a nozzle on a spare hotend and wanted to check it was hot enough while I did it. It was easiest to plug it into the chamber thermistor port. I realised it looked a bit silly and thought it was worth a post 😂

    I genuinely do have trouble with sunlu abs coming unstuck. My chamber is 60°C, and my parts are hard to remove from the bed when they don’t warp, which I think suggests my build plate is good. Have you / are you using Sunlu abs?




  • I highly doubt your nozzle is worn out unless you’ve been printing with any special tough filament (e.g. carbon fibre core). It’s completely different machine, but I have over 300 hours on mine and I haven’t had to replace the original brass nozzle yet.

    Edit: Perhaps try printing a solid section of only the first layer (no need for the whole bed, but make is fairly large). See if the lines mostly all join up, then reprint without changing anything to check if it is consistent.

    Nope, no signs of life with the battery removed and on wall power only. I believe the battery was not to blame, but something went wrong that caused it to also drain the battery. I will check the battery anyway and report back if I find anything interesting. Thanks for the helpful link.

    Current passes through it unfortunately, maybe it’s possible there is a short between coils though. The inductor doesn’t get hot or anything when plugged in.

    • I think I’ve managed to check the battery voltage, and it seems completely dead (mV).
    • I can measure 20v on the PCB whe n plugged in.
    • No fan, no LEDs, etc with either power source. There might be the slightest electrical squeek from somewhere, I will try and find out what …

    Even if I don’t manage to fix it. Thanks for the suggestions 👍
