UMO+ New User & Assembly Manual V3.0 Comments

Posted · UMO+ New User & Assembly Manual V3.0 Comments

Hello Ultimaker Community,

I received my UMO+ kit a couple of weeks ago and assembled it over the weekend. Overall, the assembly went very well, although it did take longer than I expected because I was being meticulous.

I am new to personal 3D printers, but I have a number of years of experience with the "professional" systems at work. I changed jobs a couple of years ago and have not had ready access to a printer since then, so I finally broke down and got myself the UMO+ kit. I figured that by building it myself it will be easier to maintain and mod it in the future.

I have been having a lot of fun with it impressing people with print quality. It even compared favorably to a print from a $trata$ys machine. My wife couldn't figure out why I bought it, but after I made a figurine or two for her, she now gets it :).

As I assembled the UMO+ kit, I noted a few things that might be useful for a future update of the assembly manual. Please note that these edits are mostly minor and I did not have any difficulty assembling the kit using the v3.0 manual. Sorry in advance for this long posting.

Ultimaker Original Plus Assembly Manual v3.0 Notes:

p.7: Fan pack does not include (1 ea) 1326 Warning sticker

p.7: “Feeder pack” is called out in the manual, but it is labeled “Extruder Pack” on the zip-lock bag packaging.

p.10: “Axle pack” is called out in the manual, but it is labeled “Axes Pack” on the box.

p.14: There is no “Warning sticker” included in the kit to place on the back panel.

p. 15: I needed to use a small hammer and a scrap piece of wood to set the bearings into the holes. There is no way this could have been done by hand as described in the manual.

p.16: Fig.4 shows Front, Left and Right panels, but should show Front, Left and Back panels.

p.19: Cable ducts are labeled “long” and “short” in the manual, but are labeled “front” and “back” on the zip-lock bag.

p.23: (3 ea) 1214 Lock nut should be (7 ea), and no 1209 Hex nuts are needed.

p.31: (12 ea) 1208 Hex nut should be (12 ea) 1209 Hex nut

p.46: Figure 101 is incorrectly labeled as Figure 86.

p.49: Quantity of 1028 Z linear shaft should be (2 ea), not (1 ea)

p.55: No 1326 Warning sticker was included in my kit

p.61: Step 3, “fronr” should be “front”

p.62: Step 5.1.5-1: No warning sticker included in my kit

p.70: “Feeder pack” is labeled “Extruder pack” on zip-lock bag

p.71: “M6” nut, washers and cap nut should be “M8”

p.93: 8.2.4 Sensors, Step 2: “black plug” is actually white, but the cable is black. May be better to call it “black cable”

Additional Notes:

Although the instructions say to hand tighten the PEEK isolator and brass tube to the heater block, I found that I needed to use a small wrench to tighten the connection a bit after a week or so of use. I was getting some PLA leakage that was leaving brown deposits and “boogers” on my prints until I figured out what was going on.

Also, I don’t remember seeing anywhere in the instructions to place the glass plate on the heated bed. Although this may be obvious, for completeness it would be nice to add that step to the manual.

Please take or leave these suggestions at your discretion. As I mentioned already, I had no real difficulty with the assembly, but these edits might help someone in the future. In general the v3.0 manual is very good.

Also as mentioned above, my kit did not include the “warning stickers” to place on the print head and back panel as indication in the manual. Have these been eliminated from the kit, or were they just missing from mine?

Best regards,

    • UltiMaker Cura 5.3 stable released
      In this stable release, Cura 5.3 achieves yet another huge leap forward in 3D printing thanks to material interlocking! As well as introducing an expanded recommended print settings menu and lots of print quality improvements. Not to mention, a whole bunch of new printer profiles for non-UltiMaker printers!

    • Here it is. The new UltiMaker S7
      The UltiMaker S7 is built on the success of the UltiMaker S5 and its design decisions were heavily based on feedback from customers.
      So what’s new?
      The obvious change is the S7’s height. It now includes an integrated Air Manager. This filters the exhaust air of every print and also improves build temperature stability. To further enclose the build chamber the S7 only has one magnetically latched door.
      The build stack has also been completely redesigned. A PEI-coated flexible steel build plate makes a big difference to productivity. Not only do you not need tools to pop a printed part off. But we also don’t recommend using or adhesion structures for UltiMaker materials (except PC, because...it’s PC). Along with that, 4 pins and 25 magnets make it easy to replace the flex plate perfectly – even with one hand.
      The re-engineered print head has an inductive sensor which reduces noise when probing the build plate. This effectively makes it much harder to not achieve a perfect first layer, improving overall print success. We also reversed the front fan direction (fewer plastic hairs, less maintenance), made the print core door magnets stronger, and add a sensor that helps avoid flooding.

      The UltiMaker S7 also includes quality of life improvements:
      Reliable bed tilt compensation (no more thumbscrews) 2.4 and 5 GHz Wi-Fi A 1080p camera (mounted higher for a better view) Compatibility with 280+ Marketplace materials Compatibility with S5 project files (no reslicing needed) And a whole lot more  
      Curious to see the S7 in action?
      We’re hosting a free tech demo on February 7.
      It will be live and you can ask any questions to our CTO, Miguel Calvo.

    • UltiMaker Cura Alpha 🎄 Tree Support Spotlight 🎄
      Are you a fan of tree support, but dislike the removal process and the amount of filament it uses? Then we would like to invite you to try this special release of UltiMaker Cura. Brought to you by our special community contributor @thomasrahm
      We generated a special version of Cura 5.2 called 5.3.0 Alpha + Xmas. The only changes we introduced compared to UltiMaker Cura 5.2.1 are those which are needed for the new supports. So keep in mind, this is not a sneak peek for Cura 5.3 (there are some really cool new features coming up) but a spotlight release highlighting this new version of tree supports.
