    Rather, annoyed.

    I'm a relatively new member to the Ultimaker product line, and have an Ultimaker 2 Extended--after 2 months of successful printing--I recently ran into a spot of trouble with nozzle clogs, feeder issues, under extrusion, etc... and the community, local support in the US by Dynamism and FBRC8 have been downright awesome with my printing troubles, and I'm back up and printing :)

    I think my issues were from just using the printer a lot--it's bound to need replacement parts/maintenance/etc...

    It's a bummer not to be printing--but post the issues with photos or a detailed description to the troubleshooting section and the helpful community members will get you back up and running with their awesome advice :)

    Also check for local support experts in your country--Dynamism and FBRC8 in the US are super helpful :)

    filament under extrusion?

    in UltiMaker 3D printers

    Posted

    There are a few issues that can cause things like this.

    How Many hours has your printer printed? the PTFE coupler can deform and not allow the filament to flow properly.

    It can be a nozzle clog that needs a few atomic pulls to clear or you may need to push a fine wire up the center of the nozzle when its hot and rub around the inside edge.

    Could be the feeder tension isn't enough and is slipping.

    and lots of other things that I cant remember right now.

    You can try removing the bowden tube from the top of the hot end and pushing some filament through by hand. see if there is much restriction there. if ok, look at how deep the imprint from the feeder is on the filament. if there are light marks the you can increase the feeder tension.

     

    Thanks! I reassembled the nozzle again--this time making sure that the PTFE coupler was within 1mm to the isolator Nut and I'm back up and printing :)

    Removing Temp Sensor and Heater

    in UltiMaker 3D printers

    Posted

    Just tape the new sensor to the old one and pull the new one through as you pull the old one out. just pull slowly and every now and again push or guide the new one through if it gets caught. its quite easy to do and you dont need to remove the inside panels. just make sure you tape it so there is nothing sticking out.

    undo all the clips the hold the cable to the bowden tube to help give you some more room.

     

    Thanks! That's awesome advice :)

    Removing Temp Sensor and Heater

    I found some instructors for removing the temp sensor and heater from the main board--are there any instructors for removing any panels for the temp or heater from the bundle of cables going to the print head/or any docs about threading the sensors through the print head cables or any helpful hints?

    filament under extrusion?

    in UltiMaker 3D printers

    Hi! I recently had a nozzle clog that the atomic pull didn't quick work on--I disassembled the nozzle and removed my clogging problem.

    After reassembling my nozzle--I was only able to 2 print out two items and all of the subsequent prints have failed.

    I cleaned out my nozzle again using the Atomic pull method, and when I load in filament it extrudes out. However when I try to print--the filament doesn't seem to come out fast enough and bunches up at the nozzle head--as shown in the photo below.

    I've tried cleaning out my nozzle again using the atomic pull method, and have also tried leveling my build plate again--still have the same trouble.

    When it was failing to print--it would only start the print a few layers then the filament would stop loading--now it seems like there's no filament loading at all or it seems to load or extrude too slowly.

    Also, when I had the nozzle apart a second time--I did get a heater has stopped error message.

    Any pointers on where to start with my trouble shooting would be super helpful. Thanks for helping me troubleshoot this!

    Thats one way to do it. :)Be careful not to stick anything too far up into the nozzle though as you could do some damage if you do.

    I just remembered gr5 made an excellent post about changing out the heater block which also helps with the assembly and reassembly of the print head.

    Thanks Sir! Thanks so much for all of my answering my questions! I'll reassemble the nozzle again.

    I got my nozzle unclogged by using my Hudy RC Wrench--I removed the Bowden tube and filament and used my Hudy hex wrench like an ice pick while the nozzle was heated, and I was able to push the clog through the nozzle!

    Thanks so much for letting me know about the Olsson Block it really seems to make more sense :)

    Thanks for telling me about Fbrc8 too :)

    Hello! I've been enjoying my Ultimaker2 Ext for the past 2 months and it has worked out super awesome till late last night when I experienced a clog.

    I tried unloading & loading filament--my newbie method for unclogging before--and this time it didn't work.

    I read about the Atomic pull method--and it's a great technique--and that's also when I started to into more trouble--when I heated my extruder to 220 C pushed my filament into the extruder head--then pushed with a pin at the bottom as it cooled down to 90 C --- I waited a few minutes to pull and when I pulled--my extruder head pulled further into the fan duct housing---the extruder was now about flush to the fan housing.

    I succeeded in disassembling the nozzle--pulled out the filament that got stuck in the PTFE coupler, I was going to go as far as to remove the thermometer & heater and it is stuck in the nozzle--which seems to be unmovable. As both are jammed flush right into the nozzle. Unfortunately the PTFE coupler was damaged when I tried to remove it--luckily I had a spare one from my CPE roll.

    I cleaned out the nozzle as best as I could with the probes attached, and reassembled the extruder--when I restarted--the electronics seem to work fine--but no filament extrudes--I get a small "film/coating/bulb" of plastic forming around my nozzle--and nothing prints.

    This morning I noticed that the Hot End Isolator Nut isn't flush with the bottom plating--it's sitting about 8mm above it.

    I'm wondering what to do next for my trouble shooting:

    Should I try to disassembly & reassemble the nozzle again--this time lining the Hot End Isolator Nut flush with the base plate?

    Try the Atomic pull again?

    Also--doesn't anyone have an info about how to remove the temp and heater from the nozzle? Or any doc's about what to do if you have to replace the temp and heater probes?

    And worst case--does any company service Ultimaker's here in the US? For newbie's like me baffled about how to remove the temp/heater from the nozzle?

    Also--if I do manager to get the nozzle free--does Acetone dissolve PLA as well?

    Thanks in advance for your advice and help!

    Hello Ajmonkey, thanks for your replay.

    This was my first model and is made by myself .

    I will download a 3D model and print to see if it runs well.

    May you suggest a model to test the printer?

    thank you

     

    Hi Vaz, I have experience mostly with Makerbots-- and due various problems I've had with working on Makerbots I've recently received an Ultimaker 2 Extended as a birthday gift from my wife to replace the Makerbot :) I know for Makerbots I always loved printing out the Maker Faire Robot:

    http://www.thingiverse.com/thing:40212/#files

    This is a good test for any 3d printer. And I think the Ultimaker Robot is a great test print too :)

    MadeSolid PET+ Ultimaker 2 Firmware & setting questions

    in Materials & profiles

    Posted

    There is no reason to touch firmware to print pet. What they offer is a cura profile. Basically how to optimise your print settings. I did not look at the settings they offer but in my experience pet prints fine on UM2 at higher temps. I guess at least 245c. This will shorten the life of your ptfe (the little white thing in you printhead) which can relatively easy be replaced. but best to keep a spare.

     

    Thanks for the great advice! I also emailed MadeSolid, and I just received an email from MadeSolid's CTO David Rorex--and they also tell me not to touch the firmware on the Ultimaker 2 Extended as they are working on updated instructions which should be on their website in a few days :)

    MadeSolid PET+ Ultimaker 2 Firmware & setting questions

    in Materials & profiles

    Posted

    Hi! I just recently purchased the Ultimaker 2 Extended-and am interested in printing with PET+ as there was a project I really wanted to duplicate that was printed in PET+ on YouMagine.

    I was wondering does the Made Solid firmware for Ultimaker 2 also work on the Extended and Go versions of the Ultimaker 2? Does the firmware from MadeSolid just add in the PET+ functionality? Or can I set this manually on my Ultimaker Extended?

    Here's the link to their page:

    Thanks for your help!
