I use very long tweezers to pull away the filament but it usually gets smushed around the nozzle during the level calibration. RE: Under-extrusion after nozzle change. Lack of thermal paste at the top of the heatbreak @geoper2. 9. Gummed up teeth: the extruder gear has teeth which bite into the filament, ensure that the teeth are clean and clear of any plastic. Which filament are you doing the cold pulls with? Alway use the higher temp filament for Prusa i3 mk2s started to slowly leak filament making any print unusable because it leaks from the nozzle, causing a blob, which will cause spaghetti monster Re: MK3S vs. I Prusa MK3S+ kit. There is a strange squeeze/dent in the filament when i unload it. Notifications A long filament leak when the nozzle is heating could be an indication of a few different issues with your 3D printer. If the filament can be loaded and unloaded without any problem, yet it still causes trouble during the print, clean the inside of your hotend using the Cold pull (MK3/S/+, MK2. I have tried changing the nozzle and cleaning all of the filament in the extruder. Almost sure that my case is moister. when trying to unload filament the printer would make MK3s printer; Spool Information; Print (Bed level test) My printer has been working fantastic with the grey Prusa PLA sent with my new printer. 5/S). I have totally recalibrated the printer. The stringiness just won't go away, and it's stringing at the nozzle, not coming off print. The oozing might not be immediately apparent but can be visible either through the ooze dripping Check if blobs are not coming from above the nozzle, is there some leak, if nozzle is not good installed it can leak. After reassembly I ran the calibration wizard. Feed in from the top of the extruder your tool of choice, down past the Bondtech-gear, and on top of the stuck filament. (The Slicer can't know when the Prusa MK3s Filament Loading Issue . I couldn't get the filament to come out, so while the printer was at room temperature I pulled it out with pliers. I'm thinking better filament didn't give me problems, but this filament clogged and stuff came out the top. If you still have power, now might be a good time for oven gloves make sure you have a sparePTFE Tube, Heat up the hot end, grab it with pliers or similar, remove PTFE and filament, let hot end cool on heat resistant surface, (Maybe oven gloves) No LOAD option in menu. Autoload is grabbing the new filament firmly and it extrudes the old filament color, then the new color as expected. 75 mm MK2. Re: Prusa MK3 is clicking and then under extruding. Prusament PETG Jet Black 1kg. ; On MK2. I have filament leaking over the top of the head block, but I can't screw my nozzle in more to close the gap. Partially blocked or poorly machined hotend or nozzles (usually low cost clone parts) can increase back pressure and The Prusa printer came with a melted extruder system. The new IR filament sensor still uses an optical sensor but is triggered by a mechanical action designed into the new plastic parts of Coming from CNC machining background, I would guess there's something possibly up with the original machining. Everything went back together good. The printer should squish the layers in to almost a flat sheet unless you are trying to print spaghetti, I had a fun job cleaning my hot end because the printer clogged when the print detached from the bed. the creaking noise sounds almost Filament not loading. When it is Z axis calibrating before a print, every single one of the 9 calibration points will have some plastic stuck to them, and I have to manually remove Mechanical problems: Loose pulley: ensure that the set screw of the extruder drive gear is secured against the flat side of the extruder motor shaft. Prusa SL1S and a Prusa MK3S+. Prusa uses 15mm^/s which is a tad optimistic IME. If your Prusa i3 MK3 is oozing burnt filament from the top of the heatblock, then you most likely have an incorrectly assembled hotend. Too tight and it squishes the TPU and gets stuck. 9/S, XL) Filament sensor MK3 (non-S) Flashing custom firmware (MK4/S, MK3. I grab as much as a can with a tweezers, but there are so much clumping that the plastic stuck to the side of the extruder will bump into other sections of print and mess it up. Make sure you cut the tip of the filament at an angle and then just feed it in the hole at the top of the RE: Issue: Filament not getting through? I also have this problem. Notifications If the nozzle is not snug up against the heat break inside the heater block, filament can leak out the top of the block and ooze out over the block, nozzle, and eventually the print. Hi there, please allow a couple of comments: - Checking if the teeth of the extruder gears are alligned, and although the teeth are just a teeny tiny bit misaligned, a prusa technical support employee ensured me that this shouldn't be the cause of the problem seeing how the misalignment is too Printer Not Unloading filament. There is simply nothing holding the filament in. the print continues without filament coming (when the sensor is turned off), the filament does not 'take'. Yup, unavoidable in principle, on FDM printers. It's not the firmware, either. Stringy filament is another issue I think. RE: Filament not loading, makes skipping sound. RE: Printing with Carbon Fiber Nylon? The E3D v6 on the Mk3 is an all-metal hot-end already. 9/S, MK3. Nothing happened. ) she if its close. The filament doesn't "jump" up to the nozzle. If the filament is not oozing from the nozzle at this stage, push the filament towards the extruder, and after that, select "retry". Original Prusa i3 MK3 & MK3S & MK3S+ I still think there will be problems with the blob not coming off, and for this reason I would consider having it do one more thing. Load the filament by pushing the filament coming out of the RE: Filament head too large after unload (MK3S + MMU2S) I haven't had time to play with the settings yet, waiting for the weekend. So I go Original Prusa i3 MK3 kit available to preorder at our eshop for $745/with $50 UPS Expedited But the important question is “Does it come with a kilo of filament?” Thanks Mr. It can be purchased separately from your printer. 544 kg. I know that leaking filament can either mean something is loose Stuck filament cleaners, stuck spool rollers, or other attachments obstructing filament feed. Fix the loading issue on the MMU2S where the extruder stepper motor strips out the filament. 5/S and MK3/S/+, navigate to LCD Menu -> Settings -> HW Setup -> Nozzle Change. 5, unscrew both M3x40 screws under the hexagonal window (they also have springs on them). 5 cm long for the MK3(s) and 6 cm long for the MMU2s, you are often able to simply push it through. We need high-quality for our own use – and we design our machines to meet these criteria. If the filament is not oozing from the nozzle at this Re: TPU is simply not printable with the MK3s. I come back to it now, but change the nozzle first. i just cannot seem to pinpoint where exactly it is coming from. 75 Filament used (both good and bad prints): 2. 20 hours. Notifications IF you have filament coming out the nozzle just not in a great quantity and not coming out the side of From my experience, filament doesn't like to be bent for long periods (fine during printing, but less so when left overnight or for a few days) - the stresses shatter the filament. Extruder Leaking. Newly built Prusa i3 MK3s from kit. Extruder isnt/cant push the All things related to Prusa 3D printers. for starters, Ninjaflex at 85A while being a wonderful filament, (Frankly it's my favorite flex) is far from the first flex you should be printing, you may want to try something in the 98A range to start, maybe the 95A range, get a feel for what it is your dealing with and move forward from there.
