  1. Hi,

    i tried cura 4.0 and it shows a funny behaviour.

     i am printing quite detailed min figures (with tree support and adaptive layers).

    when i slice with cura 4 sometimes the print stops during print.

    unfortunately extruder stays at the temp and it slowly forms a blob at the print. there is nothing that can be done i have to switch off the machine.

    it is actually worrying because if not attended it could start a fire of melt the extruder parts.


    i have a modified ultimaker original (a ulti2 printhead) and a selfmade heated bed.


    i suspected the power supply, but when i go back to cura 3.6 this stopping does not occur. unfortunately it is not reproducible it just happens sometimes but always when sliced with 4 and so far not with 3.6.


    anyone seen this behaviour? or has an advice what to look for, is it possible that cure 4 creates too complicated gcode?


    running out of ideas.


    thanks in advance



  2. Hi mark2 team,

    wow awesome site and upgrade. i looked through the documentation and it looks great.

    i do not want o hijack this thread but i guess the best start is here to find interested collaborators.

    my "problem" is that i have an UMO (no plus) and would love to mod it to a Mark2 but not sure where to start.

    - upgrade hotend and feeder to an um2+ x2 (if that is possible)

    - simply use a double UMO hotend (eg i have the old dual extrusion kit is that possible to reuse it?)

    - do i need the umo+ electronics ?

    so many options and i am sure every version needs a lot of testing.

    so here the question what is the best way to start and are there any interested makers out there?

    thanks again for the awesome community upgrade.

  3. also excited aboutthe upgrade. i will order my magnets today. hopefully my dual extrusion upgrade has all the parts.

    the poll is currently at 23 (UMO) versus 53 (UM2).

    would be interesting to know how many umo versus um2 have been sold and if the ratio reflects that.

    @sandervg are you allowed to give us some numbers or at least the ratio?

    @foehnsturm awesome effort. one question, any comment which noozle typ is the most recommended for an umo upgrade? or does that not matter much in terms of quality?

  4. Hi foehnsturm et al.

    below is the doodle link for the poll to identify the interest in the different possible upgrades.


    I included all four possible upgrades UMO, UMO+, UM2, UM2+ so all users can vote for their interest. I am fully aware that this might be difficult (e.g. not sure if UM2 is easy to upgrade).

    I kept is simple to these four choices. (not asking about bed upgrades, nozzles etc.)

    Please let me know if you think that is fine. Happy to change it in case I missed something.


    @greengecko, I don't mind at all, please go ahead.

    As I expect many UMOs out there already being hacked in some way, it's a good idea to collect the interested people and check if there's a common starting point and objective.  

    An UMO tool changer project will be kind of a side project as I have to focus on the UM2 to provide an almost product-like user experience for this upgrade.

    I can share the UM2 files but you would have to modify some of the parts on your own.


  5. so I was directed to this forum by sander.

    May question was why not fix the website and calling a beta a beta and directing to the last stable version of cura?

    my request was also fix it and not answer this post (at least one of your programmer agreed that this was a mistake, and about >5 posts in the forum do so),

    ...but too late...

    @SandervG: and yes I used the inappropriate button in the wrong sense I could not resist, because I am childish...

  6. HI Daid,

    That is a tough questions. I personally really like the speed, but still missing some things. E.g. plugins color change does not work (others I did not test I assume it is the same) and also some other features (half layer steps at the outside to have a better quality there). This (the skinning) is in my view something that I really miss and therefore I would not use the steam engine for most of my prints if I want to have quality. On the other side for standard prints it is really superfast and great (minus some infill jumps which potentially can be problematic if the model is ripped of , though that did not happen so far). So if you release it I would clearly mark it as a beta release and let people know that due to the nature of a beta people should be catious and for example should not print larger prints unsupervised. Also it would be good to let users know what features are still missing so they can judge by themself if they would miss something.

    Having said this I think the new slicer is really superfast and therefore will be very appealing to most people if they do not want to use too many advanced settings.


  7. Am besten Cura verwenden. Das ist fuer den Einstieg am einfachsten (verwendet den gleichen Slicer wie ReplicaterG)

    Hattest du bei netfabb das modell in den build bereich gezogen. Es hoert soch so an als ob du nur das raft hast slicen lassen.
