    UM2 Print time is much slower than my other printer?

    in UltiMaker Cura

    Posted

    I am trying to track down the setting that is slowing my ultimaker2 to nearly 2/3rds the speed of my other printers.

    I seem to have about the same settings for both, but the print time is much larger on my UM2.

    (please note, even if I change the minimum layer time, and travel to match the Prusa settings, it still was over a half hour slower on this file.)

    Is it just the difference between one printer being 1.75, and the UM2 being 2.85?

    Or am I missing a setting somewhere?

    Mechanical sympathy - Auto Shut-Down after print fin??

    One thing I have been looking into is a couple of these. http://www.belkin.com/us/p/P-F7C027/

    They allow to remotely kill power from your phone.

    For long prints, I am already in the habit of using a camera to watch it remotely. With this I could easily kill the print remotely as well.

    All can be done other ways as well, (octoprint for example), But this way it all can be set up without the need for a computer, or ras-pi.

    If you have an old smartphone laying in a drawer somewhere, then you already have a wifi connectable camera you can re-purpose it into.

     

    Teeth marks after feeder, normal? Also Feeder click.

    Still running, But I think it's clear I found the answer to my problems. Bad filament.

    With new material it is a world better.

    This is actually somewhat disappointing, these Ultimakers are full time eNABLE machines. They are both personal, and classroom used, for making hands and education.

    I was graciously donated 12 spools of older filament, to get started. Sadly I don't think the material will work.

    The bright side, is with nicer filament, the machines are going to run GREAT!!

    time to start working on building a filament collection.

    Thanks guys for helping me through this.

    Thanks for the link. Great guide.

    Turning the feeder down to the lowest setting, does seem to eliminate the clicks. But of course I know that is just masking the real issue, and not the ideal solution.

    Thanks Don for pointing me too the Roberts Feeder. After searching for more about it, and seeing how many people have gone to it, It is going on the list for sure.

    I'm new to the forum, so there is a lot to study up on, but one thing is for sure, Ultimaker makes some amazing and beautiful machines.

     

    2 Beautiful machines, printing hands for kids

    That's wonderful! :p

    It's hard to tell from pictures sometimes, but how large/small are the enable hands usually made?

     

    Thanks :)

    As for size, that all depends on the recipient. The hands are scaled to size.They could be small, for a young child, up to a full grown adult.

    The picture up above, where I am holding the red palm, that was yesterday when I finally got the clog clean, and was running a very first test print on the new printer.

    It is a small palm, but I have built one very close to that size for a young 3yr old boy, so the sizes are all over the place really.

    The first picture however, that is a different red palm actually, and is sized for an 11yr old.

    Currently I am working on a hand for a 7yr old, an 11 year old, and just met a teacher that has a 14yr old boy in her class needing one. All 3 of those will be very different sizes.

    Proud new owner of two UM2's.

    They were used machines, so I spent a good couple of days cleaning them up, and getting to know them.

    Previous users were printing in Nylon, so I fought some high temp clogs at first.

    But got them cleaned out and flowing nicely now in PLA.

    Side by side printing hands for eNABLE :)

    Both of these I will be keeping at my local makerspace, where they will now be a full time, public eNABLE station.

    Trained members will be free to use them for building hands for kids, while I am not there.

    These are going to be two busy machines!!

    I am working on 3 hands right now, so it is very busy for me and these will help greatly.

    Having these at the makerspace will allow others to help with the builds, and assist me with the classes I am going to be teaching there.

    It is one happy week for me and eNABLE!!!!

    This isn't about the hands, but still very cool.

    I was invited to my local Children's Hospital yesterday, not about the hands for kids in this case, although that is a HUGE upcoming project with them in the future.

    This invite was to the cardiatric center, to speak with one of the Heart Surgeons and a Clinical Research Nurse, about how 3D printing is benefiting heart surgery.

    Here's a brief article about what I am talking about, http://3dprint.com/1219/3d-printing-helps-fix-childs-heart-save-life/

    In short, pre-surgery, the doctors can take the MRI scan of the heart, and print out an exact copy. This eliminates the need for exploratory procedures like going in with a camera/endoscope, saving much time, thousands of dollars, and added risk of the necessary anesthesia.

    It sounds like I will be working with them on a closer basis in the future to help, not just IMPROVE lives with the eNABLE hands, but even help SAVE lives with printed heart models. Too cool.

    I printed out a demo heart to bring with me. It is more of a "toy" model I just pulled off thingiverse, but i think it's super cool anyway :)

    Oops, we posted at the same time, sorry to double post, It's much easier now to get XT here in the states since the last month or so.

    Colorfabb teamed with an online friend of mine at PrintedSolid.com, he has been keeping the colors in stock.

    He is also a great US distributer of many of the exotic filaments. Carbon fiber, woods, bronze etc..

    Not trying to promote other suppliers on here, but if anyone in the US reads this, it may help to find some XT quickly at his site.

    Maybe I will promote this to the eNABLE group, with hopes of some testing started...

    I have a spool of XT here, But have not really felt the need to use it on a hand.

    PLA with 30+ infill has worked great so far.

    XT I know would be great for some applications, maybe a larger adult hand 'utility' hand, or maybe in high temperature areas of the world where the hot sun could be a factor.

    But for the most part PLA is adequate. We have 2 adults, both working jobs that require lifting, one is a package handler actually, and they both have been able to use the hands well with standard plastics.

    I would be interested to try XT to test the surface area and smoothness of joints. PLA and ABS can both have a little squeak to them when flexing, some use various light oils to quiet the fingers.

    I AM curious to test the "sound" of XT now that I think about it...

    Thanks Sander, glad to be here!

    As for the questions Didier, James seems to have this thread covered lol. I would like to elaborate just a bit though.

    For materials, I wouldn't say PLA only. Really ABS is fine if that is a material you prefer.

    We tried to keep it PLA only for a large conference we put on at Johns Hopkins University here in the US, but we had a reason for that. For general printing otherwise ABS is fine.

    Many early on were using Nylon (Bridge mostly), which is a great material, just limited to white unless you take the time to dye it before hand.

    I am experimenting with a new material from Igus, it is an industrial filament designed for custom bearings, a self lubricating, very low friction material. I just received a sample and will be printing some fingers to try it out.

    After talking with the igus people, it sounds like it will be fine for skin safe, already used in prosthetics, but I am mostly concerned with the strength/brittle factor.

    As for sending spare parts, that is always an option, and some volunteers do send extra fingers. I personally only send extra cord/elastic, and Velcro in case the family wants to custom the fit.

    I have only heard however, one breakage in the field by actual use. That was on a very small hand, for a 3yr old. The wrist gauntlet snapped in half. That is the child I made the replacement Batman hand for.

    I didn't make his original, but I saw pictures, and really that was just because of the small scale and thin walls.

    As the child grows, the need for new hands does arise. Our little Liam, the first child that was ever fitted, I think he is on his third or fourth hand maybe? But his makers like sending him the new designs as they come out, to keep him current.

    It can become a long term relationship with a family, printing as they grow, or trying new hands when they are designed, or even just for testing if the recipient/family is willing to give feedback.

    For the question on sharing the modified designs, absolutely I would if anyone wanted them.

    The wolverine claws are up on thingiverse, but they are just a simple little design really, I think anyone could do better haha.

    They would also need to be scaled to size, and would really only fit on the Cyborg Beast without modification. The new raptor has many more exposed cables on the claw area.

    The design with the functional accessory rails is a little tougher. The rails are best if kept at 100% scale to fit standard accessory mounts.

    The best thing to do is scale the palm/hand files FIRST, then add the rail files prior to printing.

    If you are printing custom mounts to hold items like pencils, paint brushes, spoon, ect... you have a little more flexibility in how you can scale down the rails, but I like keeping them at 100% for strength reasons. They are really rock solid when done right.

    And yes, the feeling of giving a child a hand is the best! I have done and measured all mine remotely, so it's a mix of both excitement, and fear that it won't fit lol.

    Once I see the package is delivered, I will pretty much pace the house, nervous, until I see a picture or video that the hand actually fits perfect haha. Measuring and fitting from a thousand miles away has it's difficulties at times lol.

    Thanks Didier, That hand was very fun to put together, his story really touched my heart.

    They all do really, lol.

    eNABLE is a truly great group of people. Like James here, and thousands of others.

    I am just lucky to be involved.

    Here's a pic of the Batman one I finished last night.

    It is going to little 'Bubba' in Hawaii, if you saw him in the news at all. He's our most famous little superhero.

    Sadly his first IronMan hand broke, the small size of his hand makes it a bit of a challenge on the older design, the new Raptor is much stronger.

    His mom is keeping this one a surprise, and this batman one is on the way as we speak. :mrgreen:

    Hello, My name is Aaron Brown.

    I am an eNABLE volunteer and am in the process of purchasing 2 UM2's, hopefully I will become more involved with this community as I go.

    I will post a few of the eNABLE hands I have made in the past. Both for demo, and for children that have received them.

    Here are a few pictures;

    Myself with a small demo table at Mini-Makerfaire G.R.

    Now finishing up a Batman hand for a child, then moving on to the next.

    I hope to keep you all posted, and just wanted to introduce myself to the group.
