Purchased this i7 about a week ago while on sale at Michaels. Worked great then blobbed during a print job this morning. Until this point I have never done any maintenance on it or had any issues (literally a week old). I took apart the feeder assembly the way the tech support photos show and made sure it was clear. The feeder path is clear but I can see white filament in the top of the nozzle. Long story short I can’t get the stupid print head out. I’m pulling really hard but it will not move even when the thing is heated to 240 for several minutes. If I pull on the release thing much harder I am afraid it will break. It had Creality Hyper PLA in it when it jammed. Video showing me trying to pull it is here. I also have another shorter video here where when trying to load filament the little green creality gear thing that turns as the filament loads is just sitting there clicking like maybe it is stripped or something?
Try heating it to 240 again and take a declogger needle or rod and push it down until you see filament extruding. Then try to pull down and out the nozzle. You may need to pull harder. I pulled on mine the first time and it takes a little pressure to get nozzle out. Sometimes filament can get stuck around nozzle top and that can prevent you from getting it out.
Don’t shoot it like crazy! You just have to remove the silicone sock and the nozzle will then come by itself
Mine is doing exactly the same thing. Less than a month old. I’m super frustrated!
The Sparkx i7 comes from the factory with a poorly calibrated bed leveling mesh; this is the main reason everyone ends up with a plastic blob, as prints detach from the bed during the process and the AI isn’t working. The only solution for the bed mesh is to adjust it manually using the screws; I have published a detailed guide and regularly answer questions about this issue. I managed to fix my bed mesh and no longer have any problems: the prints adhere so well that it is now very difficult to remove them from the build plate.
Why didnt you dissasembly the extruder?¿ its really easy to do, just 3 screws and thats it, and you will se if theres filament or anything that blocks your nozzle . to remove the nozzle you need to heat it up first at 200 degres celcius, then put the temp to 0 why to 0 u ask? well if you tell your printer to heat up the nozzle to 200 and you take it out, what nozzle will heat up? it can end up getting an error like bad reading or so, we dont want errors, we want to do things perfects so nothing bad happens, and do the procces to take out the nozzle https://www.youtube.com/shorts/JuEMSAzPAjg
For those who don’t know, metals expand and contract when heated or cooled. Applying that logic, if the nozzle won’t come out while cold, it needs to be heated; so, we try 120 degrees. If it still doesn’t come out easily at that temperature, we try 200, and so on—testing until the nozzle comes out as smoothly as butter.
