    Get E-mail notifications

    Hi everyone, I used to get e-mail notifications from this forum when it was on the former layout/format around 1-2 months ago. Now I don't receive anymore. I tried to change setting in my profile to get notifications when a new thread has been started, but it doesn't seem to work. Is it still possible to receive e-mail notifications? If it is how can I get them? Thanks!

    Monetizing Your Printer

    On 3DHubs you can list your 3Dprinter and joining the competition. I did at the beginning in 2013, however, even if I get orders, at least a 50% of them I have to decline since people send stuff that is not printable on an Ultimaker. Also the customer service that you have to provide is quite time-consuming (accepting the order,checking STLs, explaining quality and materials,print settings, shipping or wait someone to collect, dealing with bad reviews when they don't know the difference between traditional process and consumer 3Dprinting...etc). If you have a full-time job and you don't have the 3Dprinter in your office I would say that it is not going to work, but I might be wrong. It is still "early days" on consumer market and there might be a day when Consumer brands will ask to 3D print locally to hubs. When you will have the file and the settings ready, customer service will be the only thing you will have to care about. About the object that you asked to print, usually what should concern most is the print time than the material cost.

    UMO Head Fan specifics

    Hi Peggy, thanks for your answer. Unfortunately, I broke the connector in the attempt to use it with the wires of the new fan. Thanks anyway!
  4. I have to replace the head cooling fan since there might be dust inside and is not reaching maximum speed (if I make it run at middle speed I have to start manually). I am in a bit of a rush (quite desperate though) and I can't wait the shipping time from Ultimaker. I live in UK and I bought this one from Maplin http://www.maplin.co.uk/p/50-mm-dc-cooling-fan-ry86t The problem is that the wires are not connected to the right connector . At Maplin they don't have it. I went to http://uk.rs-online.com/web/ and they weren't so keen to help me since they said that there are thousands of them and I need to know the specifics. In the pictures, I need the specific of the connector inside the red circle. Otherwise, if you know any shops in UK that has the matching fan, it is even better. Really thanks in advance to anyone keen to help.

    Heatsink Detached on Mother Board

    Many Thanks for your answer Macua!
  6. I got a second UM original and when I opened the Electronics Box I discovered that a heatsink on the mother board was detached. I mounted anyway and when I finished to build the 3D printer, I switched on and is working. My question is the absence of the heatsink is going to cause problem?I plan to use the 3D printer for long prints. Is there a way to stick this heatsink together or is better to ask for a replacement directly? Many thanks!

    Broken Delrin Clip UM Original

    An update: two replacement e-clips were causing under extrusion. The thickness of these two together was more than the original Delrin Clip. I removed one and now there is no under extrusion. However is it normal that the wooden gear is not perfectly aligned with the motor gear? I also notice that after a while it went back aligned. Anyway, I will print a copy...thanks IRobertl for sharing!(I just have to figure out how to convert a STEP file in an STL... :???: )

    Broken Delrin Clip UM Original

    Thanks for your super fast answer! I am doing a print test, hopefully is gonna work!
  9. Hi all, I broke the extruder Delrin Clip of my UM original. I had a look on the web and a guy has replaced with an e-clip. I bought myseld few of them and I applied two. I am asking if they are going to be good or they can cause malfunctions or breaking the 3D printer. What do you think or did you have had the same experience? There should be the stl available on Youmagine, but it seems the website is down, I can't access it. The Delrin Clip received with the 3D printer has a different and I am wondering if this shape is necessary for keeping the wooden gear in place. I have to leave the machine working this night and I do not want to break. Many thanks for any kind of answer!
  10. Anyway thanks a lot for your support Gr5, I submitted a ticket last 18 june to Ultimaker support, I updated the situation, but I am still waiting an answer from them.
  11. Hi Gr5, I did experiment with the power off, moving the head by hand and I need to force this movement,it's not happening easiky. I saw in videos that people can move the blocks with fingers without any pressure but it has never been my case. After I built the printer, I had been in contact with Official Customer Support of Ultimaker and they told me that since the printer was working fine anyway, it wasn't so a big deal. Indeed it has worked fine since that episode with that big model,even without smooth movement of the header and with the short belt touching the wood panel. After the episode, I dismounted pulleys,rods, X motor, I made all the changes suggested me but there are still problems: -I didn't experience missed steps or sudden shift, but I printed just that small object in the picture -however it doesn't print rounded objects correctly - the short belt doesn't touch the wood panel anymore - the belts, both short and long, do not twist - the pulleys are aligned and tighted to the rods - the movement of the header is still not smooth but I need to force it My concern is that there is something damaged or broken, I don't know a bent axis?
  12. Ok, we are getting better. In this picture the object at the top is the last one I printed, the one at the bottom is the correct one that I printed two months ago before the arising problem. It's still not rounded but it's better than the black ones and others that I printed in the meanwhile. - I added the washers to the screws of the X motor and now the short belt is not twisting and is not touching the wall - I moved also the pulleys on the rod connected to the x motor and I think the long belts are not twisting too - my long belts are also loose and the sound that I can hear is similar to the one in Erik's video - the sudden shift that has happened with the big model was probably caused by gcode weirdness as you said and as was my concern that that model was not correctly designed - your point 3, gr5: here we are. I am not able to move very easily the header with one finger in each block. The thing is that I have never been able to do it, even when I was printing properly well. However the movement on the X axis is less smoother than when I push the block on the Y axis. Probably the problem is here, but I am sure the pulleys are aligned. My concern is that the wood panels of the headers are not perpendicular each others and I need to dismount the extruder. Do you think it is the case? Thanks a lot for your help!
  13. Guys thanks for your answers! I am from UK. I am going to check and make the adjustment you suggested me. I can already tell you that when I mounted my UM Original I replaced the black screws in the pulleys with the silvery/shiney and I had tighten those as much as possible. I also made markers on the rods for checking if they were moving during the printing but it was not happening. I am going to change the alignment of the pulleys, I'll let you know how it goes. Thanks!
  14. Hi everyone, I printed very well for few months but now I got a technical problem and I am at a dead end on try to solve it. Probably the problem has been triggered when I tried to printed a big architectural model, almost the size of the building volume, I left the machine working alone and it went out of control at one point printing in the air for 2 hours. I didn't design that object and unfortunately I wasn't able to check properly the file, it was water tight but probably not the best file to be 3D printed. First of all, have a look at the pictures of these samples that showcase very well the issue. The blue one is the one that I printed before when the printer was working properly. the black ones are the latest that went wring. In the last picture you see the black one that is not circular. From my knowledge, this can happen when the short belt of one of the motor (in this case the one that is moving the X axis) is not tight enough. It has happened before so I tightened more, however what has happened is on the second picture:the object is circular but at one point during the print the extruder slipped and started to print in another position causing the dislocation of the last part of the printing(this has happened also during the printing of the big architectural model). As far as I know this can happen when there is too much friction on the axes. This is actually happening: when I am trying to move by hand the X axis it is not smooth at least as the Y axis. I moved the pulleys and tried different positions but it seems nothing is going better. The short belt of the X motor was touching the wood wall but I moved the pulleys and now is the belt is tight and doesn't touch the wood panel, however the problem persists. I checked all the pulleys and they are strongly tight to the rods. I made some videos, if you want to have a look for looking at the behaviour of the machine here the links: I had already done this checks and fixing: -the short belts of the motors do not touch the wood panels -all the pulleys are tighted to the rods and they are not slipping during the printing -the pulleys are aligned to each other -the belts are tighted Let me know if you spot anything wrong and if you need more pictures or infos. Thanks to everyone will take the time for helping me.
  15. Hi everyone and thanks again for your answer. gr5 I can confirm that only the x axis that is slipping. I am not English, so apologies if I am saying a silly thing, but I would use "jumping" rather than slipping because when it happens I hear a sharp sound, like a knock on the wood. I don't have an Ulticontroller, for the same reason I am still using Cura 13.12 but I bought the printer on October and I update to the last firmware. To sum up, from what you said, it is definitely an hardware issue and not a software issue or the design that I was trying to print. It was an STL file that was watertight but I didn't design by myself and the person that has done it hasn't done for 3D printing and it is not used to this printer. Maybe, try to printing something different from usual has triggered behaviours of the printer that I didn't experiment because I print "easier" stuff. You said friction and you gave me a clue and probably you are going to blame me :oops: for have not mentioned before that it usually occurs a failure to the z axis: when I bring long down the bed and then it needs to go up, sometimes It is audible that the motor is working but the rod doesn't move. Further, I have done a stupid thing because I didn't have oil sewing machine, I put the green lube on the x and y axis. There is a lot of friction in moving those two by hand, but the motors doesn't have any problems to do it. About the pulleys I signed and check all 10 (the 8 on long belts and the 2 on short belts for the motors). I can tell you that at 99% they are strongly tight, i leave the 1% because I am not an engineer. Instead is it possible that now there is too much tensions on the little belts? Thanks!
