    Hey Ricky, this video helped me tremendously. This is my first 3D printer, it clogged on me while I was still trying to level the bed. I can't imagine a world where I would have been able to remove the clog without your support. Incredible work, keep it up!

    I was struggling with clogs for a week now, try to figure out the reason, but you just explained me everything perfectly. Thank. Thanks for the guys for the retraction settings, pretty sure that was the reason. Mine was on 6.5!!! :-) I don't know why. But changed now, will try soon. To be honest, I love this printer. Didn't have problem with it for 2 months. Clogging just started, but thanks guys, hopefully you solved my issue. Ricky, you have a new subscriber. :-)

    Hey Ricky, I bought this printer because I wanted a smaller unit than what I already had (mega X). Was getting a bit nervous about clogs after watching a few reviews, but after watching this I’m confident it shouldn’t be too much of an issue if it happens.
    Really hope that you make a video upgrading the hot end /heat break to get rid of the tubing. Thank you

    Thank you for this guide, it helped me a lot!
    Something I noticed when I dissasembled my hotend (during my first clog no less) is that the heatsink has VERY sharp edges both where the filament enters and exits the area right before the "void", these edges slowly grind the filament creating a lot of dust that could potentially clog the nozzle. So I just grabed a phillip screwdriver and gently removed the excess material from those edges until the filament moved smoothly through it.

    I have two KP5L and one Ender 3 with Kingroon's DD extruder, and never had a single clog while printing (I had a clog when intalling the extruder to the Ender 3, but it was caused by a mistake I made). I think that gap you mention is present in most extruders with threaded throats. I use about 1mm retraction, and it seems suficient to reduce stringing. I would suggest you to check if there is something wrong with the heatbreak's fan. Maybe it's rotation is bellow the specs and it is causing the heatbreak to work hotter than it should be. The stock heatbreak's fans are not very good, I had ratling problems with them (had to dismantle and lubricate).Great video! PS: For those not familiarized with Kingroon products, basically these extruders I cited are the same as KP3S's.

    • @RickyImpey

    look into the ender hotend fix. ive got a couple machine that came with v6 hotends, clones i assumed but ive never had a clog on any of them out of almost 6 yrs of use, had partial clogs an had to change nozzles but never had a heatbreak clog on one of the v6 hotend, now for my mk8 style hotend from enders, ive had those clog on ender 3 5 3max aquila pretty much every printer u can have them on ive had them clog. i just got a couple kp3s and kp3s pro really cheap an they both are like new machines. both was sent back an i purchased them as parts only machines but both look like they are brand new an if used was only used once maybe twice. the kp3s was missing the leadscrew so i had to replace that but the kp3s pro was a complete machine an is like new but i notice when setting it up a little piece of filament sticking out the top of the extruder like it was clipped off just above so i figured it was clogged. so this will be my first clogged v6. ive got a couple extra v6 hotends that ive purchased an played with so i know how they come apart but i didnt expect this to be an issue with them. but for a fix im going to try to replace the ptfe lining in the heat break with a longer piece so it will meet closer to the top of the hotend. ive not used one setup in a direct drive configuration so that will be something i have to pay little more attention to but im sure the same type of fix will work with these v6 hotend as the mk8 hotends.

    Hotends always end up being clogged for some reason, I've had all kinds of designs, from the Geeetech ones, Ender, MK8, V6 etc... (not the very expensive ones though) all end up being clogged, its frustrating and its time consuming but what blows my mind is that one of the most popular hotend, the V6 has a round design that makes it rotates by itself while printing..very practical...I can't believe after all these years, 3D printers are getting better screens, are more user friendly etc...but the hotends still have the same flaws and the same designs.

  • @AB-eg3ei
    @AB-eg3ei Рік тому +3

    they designed the hotend that way to make inserting filament go smoothly as the large chamfer will collect the filament end nicely even if its a little bit crooked. The problem is that they thought that this upper portion of the heatsink will stay cool (as it should) and therefore not cause any clogging issues. Apparently thats not the case and even that upper part gets hot enough to melt the filament. There are a couple of ways to fix this. The cleanest way is to buy a different aftermarket heatbreak. Just search for kingroon heatbreak and you´ll find a version with a titanium throat and a copper part that connects to the heatsink. this will not only fix the clogging issue but will enable the printer to print high temperature filaments.

    • @johnwalter6410
      @johnwalter6410 7 місяців тому

      Is hands-down, the absolute worst designed hot end. I don’t even use mine anymore because it clogs every time I print and it’s damn near impossible to get the filament to even come out all the way to the end when you’re feeding the filament in the first time, it’s such a pain in the ass. I’ve just given up on it.

    Hello Ricky, this video also helped me to remove a clog. I was about to send back the machine because the dissamble looked painful and dangerous. I want to say to newbies that it's not such a big deal, i removed everything carefuly without heating anything and pushed the remaining filament that wont melt with a small allen key. Now i'm looking for Prusa slicer profiles as the one you"ve linked are for the pro version... Thanks a lot !

    • @StarBellySneetch

    Thanks dude it helped a lot, I didn't had any clog at least when I started watching the video I only wanted to dismantle my extruder to check wich parts buy extra parts. When I got to the tube part I test it with the two nuts it came out I measure the pice and just out of curiosity tried to see what would come out.... An enormous clog of filament came out 😢 I just decided to also clean the tube by heating it and just re armed everything together.

    Overall I did learn a couple of things from this video but I don't have as much trouble with clogs as you say you had. I still use Cura. I only use PLA and TPU. You never mention the shut down procedure. I always make sure the hotend has cooled to below 60 degrees before shutting the printer off. I beleave that if one removes power when the hotend is still hot there is a chance of heat creeping up bast the heatbreak and causing a clog.

    • @RickyImpey

      Hi, i'm glad you haven't had the same problems. I did consider heat soak as a factor but all of the clogs I had happened while everything was still powered with the hot end fan running. Thanks for the comment, definitely need to be considered.

    In Cura, with this style hotend, I found reducing retraction down to 0.5mm at 25 to 30mm/s reduces the amount of clogs, down to nearly zero. Also helps immensely with zits, or as the cousins over the waters call them, "Boogers!!".

  • @chuck2501

    an easier but riskier manoeuvre (what I do) is set the temp to 200 and jam something in the heatsink fan... wait for the heat too creep up to the heatsink (3-4 minutes), then tug the filament every few seconds until it pops out. No disassembly required. BUT you may start a fire or melt a fan :)

    • @RickyImpey
      @RickyImpey  Рік тому

      I effectively tried this by just unclipping the fan from the hotend and heating everything up to max temps but it still wouldn't clear for me.

  • @JosephPiwko
    @JosephPiwko Рік тому

    Hi Ricky, Im a long time viewer and Im having problems with bed leveling that I dont think you have adressed yet because your guides focus on features that my printer does not have. After purchasing my ender 5 s1 I've been having problems with leveling my bed. I manually level and when I do this I have to fully tighten the back right adjustment and practically fully loosen my front left adjustment. This is my first concern as this doesn't feel right to me. Once I get it level and then use the auto level it works fine... for about a day. I have to redo this process nearly every day. The front left side always seems to be too far away when this happens. I am not putting force on my bed in any way. I am also not even talking off the build plate. I need help I have no idea what's wrong. I would try to use nuts to lock the screws but there isn't even enough thread on the front left screw to fit a nut on.

    • @RickyImpey
      @RickyImpey  Рік тому

      Hi, I'd love to help but I don't have an Ender 5. What your printer does have though, is 4 point leveling. It's not ideal as it is possible for one screw to always be too lose if the others are tighter. Try to start with all of the 4 screws giving the same tension to the springs. Some advise tightening them all fully then loosening from there but I prefer to set all springs with zero 'pre-load' which is where the adjuster knob is only just starting to 'grab' and tension the spring before I start tramming. To get there, loosen all adjusters fully first. Once you have this starting point, try to always adjust two screws at a time along a side. For instance, to set some tension in the springs, I would wind the same amount on both fronts and then both rears, I never do large adjustments on just one corner.
      Once you have roughly equal tension on each corner, then you can start looking at making adjustments to get the bed parallel to the nozzle movements (tramming). If you need to adjust more than about 1mm then try to again adjust a whole side rather than just one corner. If you are able to do this, you should be able to get your bed trammed whilst also keeping good tension on all springs. Really hope this helps.

    great video, right on the money!!! thanks for demystifying those clogs for me! They usually happened when I would run out of filament, now I know why - filament melts over inside heat sink and blob is formed - exactly in the place that you described. After I watched your video I verified that blob was formed and that would prevent the filament from extruding.
    Was anyone able to find a drop in replacement heat sink assembly? Would some form of e3d clone be able to resolve this issue for good?
