I have a HE3D prusa XI3 printer with an MK8 extruder. While printing or testing, the extruder makes a clicking noise as if the filament isnt getting hot enough to extrude. I began my investigation and read about many reasons why this could be happening. Eliminating most of them, I finally took off the fan on the extruder and looked at it while it was trying to extrude. I noticed the teflon tubing and tried to push it back into the throat. Then the extruder worked fine. I put everything back together and began testing again. The clicking came back, - I then took the fan and heatsink back off and there it was again. Pushing back down and this time extruding some material and noticing the tubing slowly coming up. Is there anyway to fix this without upgrading to a better hot end?
It looks like you got too tight nozzle, too cold hotend or extruding speed is too high (all could be in the same time of course). As filament goes into the teflon tube (coldend) and then into hotend it doesn't have enough time to go out throught the nozzle. So it causes that melted filament accumulates in hotend and pushes out teflon tube.

SOLVED: I replaced the leads coming from the fan motor and it is working just fine. Thanks for the input. If anyone else has this model, I would suggest printing and installing a wire clip in order... recently. The fan used to run just fine (for the past 3 months in fact--since purchase). I cannot be certain, but this may be related to the cord getting snagged by the hot-end last week (cables have... disassembled the cable bundle leading to the fan and hot-end. I have found a connection point where the fan plugs into an extension cable which goes to the control board. I have applied current here
My Makerbot Replicactor V2 constantly jams. Usually when I go to use it after it's been off for a few hours the filament has jammed and I have to take off the front fan to remove the filament. Today, after going through the usual rigmarole of having to take the front fan and fan guard off, remove the filament, cut it and then load it back in I found that there was another problem. It appears something is jammed inside the hot end itself. When I loaded the filament back into the machine, it took it but nothing came out of the nozzle, instead it all pooled up around the aluminium mounting
I'm using a CraftBot original to print PLA, but some of the filament has become stuck in the teeth of the extruder gear on its way into the hot end. I'm having issues with the gear becoming stuck and "clicking" instead of turning, and I suspect it is because of the clogged teeth. I haven't changed materials in a long time. I've cleared several print head clogs, but each time the gear gets back around to the one spot, it seems to get stuck again. Are there any good ways to clean this gear? I was thinking of putting it in a toaster oven and trying to melt the PLA off it, ideally without
First off - I'm rather new to this and I might be on the wrong track altogether... I'm printing PLA using a simple DIY XYZ printer with a direct-driven extruder, 0.3 mm nozzle, 0.2 mm layer heights, using Slic3r. I've tried to calibrate the bed as level as I can. I believe the distance to be OK because the skirt prints in straight lines with no wobble. While the overall results aren't that bad... increased the flow setting for the first layer in the printer menu to 135 - that seems to do the trick, but I have to turn the setting back again on the second layer Now - is this the right way to fix
I have a monoprice printer, works great. .4mm nozzle. I bought a number of PLA solid colors and they all print reliably. I also bought 2 rolls of PLA translucent colors, and I have lots of trouble printing with them. What I eventually noticed was that when the translucent filaments extrude, they come out in a noticeably thinner stream. Not sure why, I've tried increasing the hot end temperature and printing slower, but nothing seems to help. The effect seems to be that not enough filament comes out from the nozzle for the speed the head is printing at. I use cura for the slicer, and I've
is that a thin layer came off the printbed - After testing with a multimeter, I realized that the metal under this layer is connected to power. As both the bed and hotend were heating, I believe I may... was getting correct temperature readings before that. Also, I have a second extruder thermistor port that is unused. If I did damage my board, could I edit pins.h and configuration.h to use this port...I just got my HICTOP Prusa i3 Aluminium frame printer and finished putting it together. After setting it to preheat, I realized the bed was not level - I adjusted it and accidentally caused the head
and then again at 215°C with the same filament and it stops at the same exact point. I also tried M3D brand white filament. I am using CURA slicer with Octoprint GCODE sender and M3D Fio. I know it is not clogged because if I stop the print and press extrude without letting it cool down, it extrudes fine. What is causing my printer to stop printing? ...I have an M3D Micro 3D printer that printed fine for a couple of weeks and then was plagued with issues afterward. I've done the fixes from the forum to get proper heating and cooling of the nozzle
I own a delta 3D printer. The problem is that, at the beginning of a print the extruder outputs dirty filament. I want a clean filament flow at the start of my prints! How can I make the hotend exit the print surface (glass plate) by 10mm, extrude the bad filament and go back to printing again? Can this be done with G-code? My Z high is 190mm and the glass plate diameter is 120 mm. I'm using Marlin + Ramps 1.4.
. No warping or peeling off. However, after a few layers, it clogs up and stops extruding. I am using an HIC PRUSA I3 printer with a single extruder head. I've only had the printer for a couple weeks..., to figure out a solution... Take a look at the image below. There is a 1 inch tube that goes from the heat element to the heat sink. This 1 inch of tubing is REALLY hot and larger than 1.75mm. So...I'm using brand new PLA filament and am getting frequent clogs in my extruder. I've had this problem with 2 different filaments from 2 different vendors. It will be print just fine, then clog up
