  1. I think it is something with Mojave and Cura that has made the app more or less unusable, and not only Cura. I use both Cura and S3D on an MBA that only has Intel Graphics and in the past (as in pre-Mojave) zooming etc. was ok...but now both of them are soo slooow that I hardly want to look at the sliced model 😞 Everything else works ok...and even Fusion360 still works just as fine as it did pre-Mojave.


    For Nvidia cards Mojave is the beginning of the end with Apple, sadly, as they have more or less dropped support for those cards and users are reporting performance issues with Mojave.

    Also you need to replositon the limit switches as the axis are rotated by 90 degrees. You don’t need to print a new top to the UM2+ hot end if you upgrade the sliders and pulleys.

    If you print the rotated top there is no need to reposition the switches. Ofc that works too, but imo it is easier to replace the plastic top.

    Do you change the Firmware from the UMO+ to the Firmware from the UM2+ or any custom Firmware or can i use the Umo+ Firmware in the Future?

    Get the UMO(+) firmware from @amedee, configure the options you want on the website and it will build a new custom firmware for you:



    As for slide blocks, I can recommend these:



    They allow you to utilize a bit more build volume, and you can easily adjust the belt tension.

  3. That firmware is a fork and major improvment to the UMO+ firmware...and is what, afaik, everyone that tinkers with their UMO(+) printers are using.

    You can easily build it with the webtool he put online at https://bultimaker.bulles.eu/


    If you are modding the firmware you could download that tool and run it locally to compile the firmware...and if you make a new (awesome) change to the firmware send him a pull request 🙂

    Curs 3.5 is soooooo sloooooow on my core 2 duo iMac running El Cap. Tons of pinwheels in layer mode. I think I'll have to switch back to 3.4x until this gets ironed out.

    Even 3.4 is sloow on a Mac if you are used to the speed of S3D...the UI is decent...but could be alot better...slicing though...that takes forever. Using Cura makes the coffe machine work hard as there is a lot of waiting involved ?

    I am thinking about buying an chinese UM2+ print head for my UMO+.

    Has anyone experience with the chinese UM2+ head? It is less then the fifth of the price of the upgrade kit. 



    It's a hit-or-miss game buying parts from China...you may get lucky and it is of decent (still not excellent) quality...but most of the time you will find that the quality is crap. A quick search here will reveal many posts where you can see how bad they actually are.


    My 2 cent advise is to either buy the official parts as @ultiarjan suggested...or look on eBay et.al. for people selling of parts when they have upgraded their UM2 to UM2+ (that is how I got hold of two printheads in used, but very good condition).

  6. Building an UM2 Extended clone vs. an UMO+ clone is no difference.


    Personally I would ditch the UM boards and use a Duet3D, or some other modern board. But if you look around there is a clone-v2.1.5 version of the UM2 board with removable steppers available. But given that it is a clone I would not buy it...it's a hit-or-miss kind of chance not worth taking imo. That said, using a different board means no more UM firmware...so it will no longer be a 1-1 clone.


    If you want to keep the UMO board and change stepper you can also build an UMO Extended...just make the side panels higher...all you need to change in the software config is the height of the build area.


    If you want an amazing extruder I can recommend the Zero Gravity Extruder. I, and a few more, have been using it for a long time and it is awesome...regardless if you are printing stiff or flexible filaments.


    Rods can be bought from many places...Misumi if you want the best...Robotdigg (or similar places) if you want to save some money.


    If you look at the Ultimaker 2 Aluminium Extrusion clone at Thingiverse you will find hints on where you can source material used to build an Ultimaker clone.

  7. Ok, found it, installed it, had to figure out where it was supposed to be, until I discovered that I need to go looking for hidden settings...and there are lots of them...oh my...but at least I have, finally, easy access to that setting...


    Still curious as to why everyone, especially the developers, strongly says that changing nozzle size is not needed and that changing line width is the same thing...

    the latest version of cura doesnt even list nozzle size since it doesnt really matter, what matters is the line width. just use the latest cura (3.2) and you wont have this issue anymore


    This is utterly confusing...


    Why, if nozzle size is irrelevant, did you put it as a configurable setting in the machine settings?

    And, if nozzle size is irrelevant, how would you tell Cura to over-/under-extrude using a specific nozzle size?

    (Say I want to print with line width 0.3 using a 0.4 nozzle vs. printing with one width 0.3 using a 0.3 nozzle?

  9. Being "forced" to use Edge (Windows 10 + Edge) as my browser sometimes I have noticed recenly that when I have clicked on a notification and opened it in a new tab...when I switch to that tab scrolling no longer works. The page is "frozen"...neither the scroll wheel, the scroll list or page down/up works. Reloading does not help. But if I alter the URL and remove the "#comment-XYZ" and load the page scrolling works again.


    Not sure if it is this computer that is acting up...or the browser. But the fact is that it happens only on this forum...no other site I visit exhibits the same weird behavior.

    The notifications are gone but then and so I do not see anymore which I had already read, or wanted to write on the desktop.


    This is the biggest downside to the new forum...

    Once you have clicked on the notification icon...all notifications are "marked as read" when you go back to that menu. Yes, they are still there...but you can't see which ones you haven't read.

  11. There are people using both E3Dv6 and UM2 print heads on UMO(+), me included (using an UM2 head on an UMO+).

    For the UMO it takes a bit more since the motherboard is not the same as on the UM2.

    But it is still doable.


    Here is some useful info if you want to take the UM2 route:


    I haven't used the E3Dv6 myself but one drawback seems to be that you can have issues printing PLA since it is an all-metal hotend. On the other hand, it allows you to use materials that requires high temps without worrying about a coupler that might be damaged.

    If you are comfortable with building the UMO firmware then a UMO is fine.  If you don't want to build the firmware yourself then you will need to go with UM2 firmware as there is much more help there.  People will build firmware for you or more likely use the same version of firmware that rajil has.


    Also the UM2 firmware has more features such as "continue failed print" and ability to adjust steps/mm without rebuilding the firmware and several more handy things that aren't critical.



    Building custom firmware for UMO(+) is dead simple...use @amedee's online builder...it covers most cases.

    It also contains a lot more features than the stock firmware.

  13. I haven't thought much about it...but if I follow a notification link now it seems to work fine  :)

    The pagination issue is more that you can't use pagination at all because it will scroll further than what the available screen area is...so you are forced to use arrows or the mouse...which is not as simple as pagination.
