    Dimensional accuracy

    Great! just what I need. Now I will be able to get rid of all the 0.2mm adjustments in my designs using this info. Thank you

    "Big" blob and huge retraction UM3 after abort

    In my experience the blob occurs at the start of the "next" print after the abort. In most cases I am trying to reprint after the initial failed print, it is at the prime of the the next print where I get an oversized blob and a long delay during prime before the printhead moves to the start of actual object. Perhaps my ssue is not what other responses are describing?

    "Big" blob and huge retraction UM3 after abort

    I have witnessed a similar problem several times after "abort print". It normally occurs during the extrusion of the prime blob. The print head buries itself in the prime blob, stays there for an extended period (much longer than a normal prime blob operation). It then drags the extra large prime blob across to the start of the printed part. At this point I normally abort the print and stop and clean the print head which is coated with filament. I have not noticed the large retraction, it may be occurring, but my attention is normally focused on cleaning the printhead. This never seems to happen after a fresh startup, only after an "abort print". I have the latest firmware in my UM3
  4. I am using the Ultimaker Breakaway filament and I live in a humid environment. I have humidity issues with nylon and PLA filament which I have solved by storing the filaments in a dry box, and by drying the filaments with a PrintDry heater. Due to physical issues on my part, I can't easily load and unload my UM3 with new filament. Hence I like to keep my Breakaway filament on the back of the UM3, loaded in feeder 2. The Ultimaker advertising for Breakaway states that it is less moisture sensitive than PVA, the Ultimaker technical data sheet also states that Breakaway is a mixture of Polyurethane and PLA. Both PLA and polyurethane are somewhat hygroscopic. My questions: 1. Is the Ultimaker Breakaway filament hydroscopic (absorbs water from the atmosphere)? 2. Can it be ruined by leaving it in a humid atmosphere? 3. Can it be safely dried by using a heater? 4. What is the suggested temperature to dry UM Breakaway? I welcome all specific feedback.

    Breakaway filament - Is it Hygroscopic?

    Thank you for the feedback, I appreciate receiving information specific to using breakaway filament. I have been experimenting with breakaway and I have found that it works really well on support area locations that can easily be accessed and a larger piece can be pulled off in one chunk. But if there are any areas that are even slightly locked in due to an overhang or pocket in the subject, then the breakaway filament can be a real problem to remove. It comes off in tiny bits and can take a long time to clean up. Back to the hygroscopic question. I had left the breakaway filament exposed on the back of my UM3 for a week now. The ambient temp in my house is 24C and the RH is 60%. I live in a tropical location and both the temp and RH can routinely go much higher. After being exposed for this long I was pleased to find that the breakaway printed very well without any signs of water absorption. I was printing last night using the breakaway as a support for some MatterHackers nylon pro and the parts we're printing perfectly (at least to my criteria). I keep the nylon permanently feeding from a PrintDry set at 50C and this seems to work well. So far, I am reasonably happy with the performance of the breakaway filament, especially in humid conditions. I ended up destroying my part though, because I could not get the breakaway out from under an extreme overhang after using default Cura supports. I think custom supports will be really helpful with breakaway.

    Breakaway filament - Is it Hygroscopic?

    Thank you for the feedback. I considered the Polybox system prior to my purchase of an airtight storage box from Target and some $3.00 digital RH/Temp gauges from Ebay. I also purchased a PrintDry system. I keep some desiccant in the Target box along with the bulk of my filaments, and I monitor the RH/Temp with a digital gauge. I print my PVA and Nylon fed directly from my PrintDry system, I monitor the humidity there also. This keeps the water content of those two types filaments under control. I don't have any problems with my nylon and PVA using this system. The quality of my nylon prints improved dramatically using this system. I keep my Breakaway filament on the back of the UM. My question related more to the technical specs of the Breakaway filament. This is an Ultimaker product so I would expect someone from Ultimaker might provide the information. I live in a humid environment with warm temperatures. Many people don't understand the relationship between relative humidity (%RH), temperature, and the mass of water in the air at a given temperature. 86 deg F air, at 50%RH, contains almost double the mass of water compared to air 68 deg F at 50%. I believe this has a greater effect on the print quality than many realize, even beyond all the YouTube videos and product warnings that are out there. I have had Nylon start printing stringy after a day being left outside of my PrintDry. It was rectified after putting it back for 24 hours. Sorry for making this comment so long, my real objective is just to get some scientific benchmarks around a new filament so that can all start understanding it more thoroughly.

    Yep, Amazon advertises eSun at 2.85mm, eSun China specs state 2.90mm to 3.0mm - who can you trust? Good thing I don't use eSun.

    Where to buy in US

    Yes, I believe you are correct, though I notice that many popular brands of filaments are specifically noting that their filaments are within the 2.85mm specification nowadays (2.85mm +/- 0.05mm) so that purchasers don't get confused. It does warrant a check before you press the 'buy' button. One of the filaments that I checked is eSun, which many call out as a low cost and popular filament.

    No problem, you need to make a decision based on your requirements. For me, I realized that I may pay more for the 2.85mm filament, but I made a choice, if I was willing to pay $3,500 for a quality printer, then I should also be willing to pay more for the filament, the quality of the output was the most important for me. Another way to look at it is if I pay $3,500 for a printer, then I am likely to spend about the same amount for filament over a period of time. Allow $42/kg for the PLA Pro. $3,500/$42 = 83kg of filament. If you pay $20/kg for cheap PLA, then that is 175kg of filament. You will probably waste a lot of the $20/kg than the $42/kg. So what is my point, its a balance of quality/cost/time, it is always the decision we make. Its all fun in the end.

    I live in Hawaii and purchased my UM3 from Matterhackers. I have been very happy with their filaments and support. They ship all there products anywhere in the USA for free. BTW I would not let the size of the filament spool dictate your choice on the suitability of the UM3. I say this because you mentioned your desire to use PVA support material. If you use PVA filament you will almost certainly start using a drybox to keep the humidity incheck in the PVA filament. I purchased a PrintDry system to dry the filament while I am printing. Here in Honolulu the humidity ranges from 60% to 100% and keeping the filament dry is essential for PVA to print properly. You can put a big roll of PLA on the back of the UM3 and then run the PVA from the drybox. Nylon needs the same treatment also.
  11. It happened to me recently too on my UM3. When I changed filament from generic filament, back to UM filament with a RFID. Apparently Cura and my UM3 decided there was a misconfiguration, so Cura Connect halted any further network printing until until the misconfiguration was rectified. The misconfiguration can be overridden on the Cura Connect screen. Of course it may have been an UM3 communication issue too, I have been getting a few of those lately. BTW, I don't believe Cura Connect print management is very helpful if there is just one user of an UM3, it seems to get in the way more than it helps.

    How to remote control Ultimaker 3?

    Hi robinmdh, Yes putting tap over the sensor is a good idea, especially if the mouse is dedicated to the UM3. I am not too worried about the issue, and I don’t want cause undue work for the devs. Using the scroll wheel is great for me, especially when I am round the back of printer trying to feed new filament, no more struggling with the little lever, now I can casually wind the scroll wheel and feed the filament in, it grabs nicely. if a job is worth doing, then it is worth doing well!

    How to remote control Ultimaker 3?

    As a follow up to testing the mouse/trackball. I have found that I make a number of unintentional scrolling of the UM3 wheel when I pick up or set down the mouse. I have found the best use is to not move the mouse to try and make changes, but to use the middle scroll wheel of the the mouse, then tap the left hand mouse button to select. Perhaps turn down the movement sensitivity or turn off the mouse movement option? This may not work for all users however. In the meantime, this simple mod has made my use of the equipment so much easier. If you would like me to comment on my use of this firmware in a different section then please let me know?

    How to remote control Ultimaker 3?

    I have been testing the v4.2.90.20180112-test firmware and it is working well to control my UM3 with a wireless mouse. I am finding the sensitivity about right for me. The center wheel controls the scroll, and the center button or left hand button controls selection. This works well if you have trouble using the UM3 scroll/select wheel. Thank you for listening and implementing a good solution.

    Good to know. I am looking forward to using my trackpad with my UM3.

    How to remote control Ultimaker 3?

    I am looking forward to the results. An alternative arrangement: since many mice have a scroll wheel, assign the scroll to emulate the turning of the UM3 wheel and mouse click to emulate selection. This would avoid unintended selections caused by inadvertent left right movement of the mouse. This works well with a trackball too.

    How to remote control Ultimaker 3?

    With physical disabilities everyone is different. Mine is an issue of strength, dexterity, finger control and accessibility, also I have difficulty reaching things. I knew that my use of the UM3 would be a challenge for me, but I accept that. We all need to do things that challenge ourselves. I find operating the push/rotate button quite a challenge. Specifically when turning the rotate I always overshoot, and when pushing to select I frequently turn the rotate wheel slightly and inadvertently select the incorrect menu item. In itself this may not seem much, but after several iterations trying to make one selection, frustration rises. I don't have any problem reading the menu items on the screen. A different input method may work, I have a trackball (Kensington with a scroll wheel) that is easy operate, many people with disabilities use trackballs in lieu of a mouse. If I could plug my trackball into the USB and operate the menu, then it would work. I actually thought the best way to solve this, for me, would be through a screen interface such as a tablet or laptop. A menu item or widget in Cura comes to mind. This is what brought me to this topic. If this feature were implemented then the UM3 screen output would likely need to be echoed onto the remote screen. I understand that Ultimakers are used in many different environments, and such a solution would likely be an issue where one machine has many users. Since you asked, other challenges are the following. 1. Loading filament in the feeder - issue - not enough strength to operate the lever on the side of the feeder. 2. Lubricating all the parts - issue - I can't reach them. 3. Getting prints to stick to the bed - issue - I am still learning. I don't have any problem printing, and designing new things to print. Sorry this comment is so far off topic, I apologize in advance to everyone. Thank you for asking me.

    How to remote control Ultimaker 3?

    Thank you for the reply @Daid! I understand the safety/security/operational requirements to be present at the machine. My need is more a physical one. I am a quadriplegic. The UM3 is 1 meter away from me but I cannot adequately operate the control (turn the dial and push select) but I can operate the interface of a screen input (tablet, smartphone, touch screen etc). In the sense that I wish to use a separate input interface, this is the type of remote control I am looking for. Perhaps I should open a new topic?

    How to remote control Ultimaker 3?

    Sorry if I confused some of the responders. Just to be clear, I am interested in the "remote control" of the UM3. In other words, complete control of the UM3 through some action other than the of physical input and response through the UM3 "jog and select" wheel. Also, not through the use of a mouse, either physically connected, or remotely connected to the UM3. I control and recieve response from a number of devices already using SSH. I am looking for a little discussion and documentation as to the functions available using SSH as it relates to the UM3. Would you consider this request a separate topic? l agree, an alternate means of direct input using an enhanced "jog and select" wheel or mouse deserves some attention and should be addressed in a separate topic. Please point me to that discussion, or I can start a new one.

    How to remote control Ultimaker 3?

    I am interested in this topic. I am a quadriplegic and I have a UM3. I have very limited use of my fingers. Rotating and pressing the dial wheel is very difficult for me. I am very comfortable using computers however, and I can develop small utilities in a number of computer languages. Can all of the actions and required responses of the dial wheel be accessed in deleloper mode through SSH (or any other means)? Currently I am moving from my computer in Cura and my modeling programs to my UM3, I struggle with the dial using my knuckles and frequently select the wrong menu item. Any help with this will be great. If the information is available in some documentation that's all I need.
