  1. You can access digital factory using webpage on your phone. I use both app and digital factory for UM3 as digital factory lacks features that the app has. It's a pain but I think the focus will be put more into digital factory and hopefully gain more features there for UM3. 

  2. Sorry it was meant to be retractions. 

    Stupid auto correct.

     

    Yeah it's meant to be more clear/ white. The more moisture it gets the more yellow.

     

    There is a difference in side of glass. Sticker side is the side your meant to use. Some materials it doesn't matter but it always helps to have it the correct way around. 

     

  3. Normally you can if its gone bad if it hisses and crackles when it prints or if the roll looks quite yellow . I have had one roll that's was bad from new but generally it should be good. 

     

    Does it have a lot of retractions On the parts that are not printing well?

     

    Does the glass plate have the warning sticker facing up?

     

  4. Yes the wires still need swapping as when you install the kit on an UM2 ultimaker tell you to install the UM2+ firmware. In this firmware the direction is reversed. Swapping the wires allows you to reverse it without firmware change.

     

    Not sure about motor size difference. I'm sure when I j stalled the kit on my um2 it was the same size as the old one.

     

    I would stick to the original um2go feeder then. It will also give your feeder better resolution.

  5. Looks like there is a lip on the top of the part that sticks out and why it's creating support. 

     

    You can add support blocker to the top section of you part and will stop your unwanted support. 

     

    Sometimes I try to adjust the support angle from 45 deg to 60 to reduce support on angled parts.

  6. Hey.

     

    It's uses 2.85 but the default feeder is very weak. If the PTFE coupler is old then it won't feed properly and may need replacing. 

     

    You should be able to edit and create material profiles on the printer menu or downloading the material data onto the sd card then editing the text file. 

     

    There are heat bed kits on eBay that look quite good. Like the UM2+ pcb ones. But I haven't tried one. 

     

    I laser cut my own front door and haven't made a top enclosure for it though.

     

    No problem using flex plate. Look on eBay as there are a few UM2go things on there. Quality can vary but as UM didn't sell huge numbers of the UM2go it's hard to find proper stores with parts for them. 

  7. The feeder that comes in the extrusion upgrade kit has gears unlike the original UM2go one.

    Because of these gears it means the E steps need to be changed so that it will extrude the correct amount of material. Also the gears change the direction the feeder will be turning, so yes the wires on the stepper motor need reversing.

     

    There are different ways to change the E steps. Using the tinkergnome firmware is the best as you can change the E Steps in the menu and still use the material change option. 

     

    Also a lot of people don't use the material change menu because it's slow. You can just lift the lever on the feeder and pull out the old material then push in the new one. 

     

    If you ever get stuck just ask. I would have provided some photos to help explain a bit better but I'm unable to right now. 

  8. Hi @medicalmodeller

     

    Yes the feeder cover is only if you want it to fit in the case after doing the plus upgrade. You can just use the plus upgrade feeder if you don't need it to fit in the case. 

     

    If you install the custom firmware then you can change the the E steps in the menu and it also allows you to use heated bed. The custom firmware gives a lot of great features.

     

    So you can install the upgrade and custom firmware that's it if you want. 

     

    You can also change the E steps by sending the following code to the printer.

    M92 E369

    M500

    And this will set the correct E steps. But if you do it that way you can't use the material change in the menu as it will be too fast. 

     

     

     

  9. It's ok, I don't think your trying to be smart. A lot of people have a misunderstanding of how it works and it's good to know as it can help problem-solve if you do. 

    The sensor is on the bottom of the print head. It's on the bottom of the front fan door. If you open the fan door and look inside you can see 2 wires connecting to the base. That's the sensor. 

     

    You can read about how it works HERE as it is the same one as in the UM3 and this link has a full better description of the whole background of how's it works and why. The only difference is on the S5 it has more measuring points not just 3 which helps it compensate for imperfections in the glass and also you can't turn off the feature. 

  10. On the S5 The sensor in the print head is measuring the alloy plate. As the print head gets closer the sensor reading is increasing. When the print head touches the glass the sensor reading stops increasing and stays constant. At this point the printer knows that it is touching the glass and stops.

  11. When the printer is active levelling it has a sensor that is reading the aluminium plate under the glass. Putting an additional 10mm of plastic on top of the glass would probably put it out of the sensors range so it won't work. 

    The only thing I can think of is to put tin foil on top of your 10mm panel. It would have to be without wrinkles and then quickly remove it after levelling (if it works) when the cores are heating to print. 

    The tin foil should be thin enough to not offset your bottom layer any more but may get damaged during levelling.

  12. It's more like acetone ABS, smooth and shiny. 

    I don't have a before but you can see it's very smooth. 

    Depends on how long you leave it depends on how much it smooths it. 

    You can also use Chloroform to melt 2 parts together.
