Still no Cura for me. (sigh) I tried the new 3.1 and still same results. {The application was unable to start correctly (0xc000007b)} Anyone else have similar results? Anyone else have any suggestions? I REALLY need the new version of Cura to help me print with PVA. (and all the other new stuff/ improvements it has.) My wife spent the last several days updating my computer and fixing a bunch of updates and got it cleaned up and all, but still the same results for Cura. "This usually means your visual basic distribution is corrupted." Is it still presumed that my Visual Basic is corrupted even after I re-installed it manually with no luck?

Here are a couple images just to update on where I'm at now. Very exciting to have successfully printed a dual color print! I have been swamped lately so not able to experiment more just yet, but going to work with ooze shields and order some PVA to get started with dissolvable supports. I think that is going to be the solution to being able to start printing quality prints for my customers. First image isfrom when it "grabbed" some of the purged plastic and drug it over to my print. Had to stop that one. The second is my very first succesful 2 color print. I know it's not the traffic cone. It's actually a customers part. I figured why not try something that I will actually be needing to print eventually. Enjoy.

Wow! That took a while to figure out. :( Yes, please change "Upload 3D print" to something like "upload image OR 3d Print". My 2 cents Edit: I just tried to upload my images from the gallery in the forum post I was writing, only to find out my image was not there. ? I see by choosing "image gallery" in the body of the post you are writing you can access your gallery. Is that really the only way to access it? There is an icon for "image gallery" AND "3D print gallery" but there is only the option to "upload 3D print" via any blue buttons on top of the page. Where is the "upload image" blue button? - Confused.

Thanks. I will try that option as well and see what happens. I have only been using PLA for starters to really get a handle on things before I venture out into more materials.

Checked it. No Cura folder there for me.

Thanks all! Tinkergnome sent me a link to some older definition files and they worked!! I started my first Dual Nozzle print this morning. Unfortunately I had a couple setbacks. One of my magnets pulled out of the stationary head assembly and stuck to the secondary head and messed up the print. I will have to re-set and glue it better this time. It made it halfway through the print, however, and it was working quite well. One other issue I had was that the second nozzle did pick up the mass of purged plastic at one point and drug it over to the print and started printing with it in the way. Kind of messed it up a little. I think with a prime tower this will go away? I just have to figure out using prime towers and being better at gluing my magnets and I am in business as a dual printer. (now if I can just get the latest Cura to work on my system lol) Thank you to all who have been trying to help with this. It's been quite a journey, but I can see the light at the end of the tunnel finally.

Thank you. I'm sure it has to be something with my computer. I'm just not sure what. So, what I did was go into my Ultimaker settings on the machine and moved it around by hand (thumbwheel). It shows the front left corner as being X and Y 0.000 (not back left where it "homes") That's where I came up with that assumption. So if I get 2.7 working, I can ignore this and assume center of buildplate is X and Y 0.000? What does version 2.3 use? Right, but is it the tip of nozzle to the bottom of the lowest axis rod? (this being the Y axis rod since it is much lower than the X axis) Or is it not that critical? Unfortunately my only options are: RepRap (Marlin/Sprinter) UltiGcode Repetier Or is "UltiGcode" Ultimaker 2? Any idea if I can get older definitions files to be able to work with 2.3? Thanks all! Keep the ideas coming please.

I should clarify something. I can not open Cura versions past 2.3 That part has nothing to do with the Mark 2 upgrade. I am forced to use the older version of Cura from something to do with my computer I'm sure. Just no idea what. Sorry for any confusion.

I have finally successfully implemented the Mark 2 upgrade to my printer. I have been trying to upgrade Cura, to no success, past version 2.3 (see my other posts) So, Cura 2.3 it is. I was able to copy all the folders it tells me to on the Mark 2 website. Now when I load Cura it comes up with the Mark 2 for Ultimaker 2 printer as my printer. The problem is, once I upload a file (ANY file) it sais "unable to slice" And no matter what print settings I change, it won't go away. When I switch back to the Ultimaker 2 extended +, everything is fine and back to working like normal. So I thought I would look at the “machine settings” for both and compare them to be sure that’s not what is causing problems. The only thing wrong with this idea is that you can not see “machine settings” or anything of the like for the Ultimaker 2 Extended + printer, ONLY the Mark 2. So then I thought I better go and see if those numbers look correct in there, but I could find nothing that helps me with how to interpret these numbers. (I’m talking about the printhead settings now) I found a couple topics in the forum that talk briefly about it, but they give no explanation as to how to interpret them or to what they should be. X min = 44 mm OK. so does this mean that this setting is telling Cura that the machine can only move in X 44 mm in the negative direction from 0? Because my machine (and I’m sure all other Ultimakers) have X 0.000 as the back left corner and it can move absolutely 0mm in X negative from here. So then should the X min be zero and the X max be some number that ensures that head number 1 doesn’t hit head number 2? And If so, how do I figure out that number? (Same question for Y axis) “Gantry Height” What is this? Is this the distance from the tip of the nozzle to the lowest point of the lowest guide rod? I see that there is a “Machine Center is Zero” option to check or not to check. Does this mean that if I check this, the machine will now think that the center is X and Y 0.000 and not the front left corner? There is also a ”Gcode flavor” option. How does anyone know which one to choose? What are the differences? Thank you Jason Brown

Found a log file. It was all about 2.3 though. Deleted it (and entire folder) and still same results. Event Viewer was completely full of events. (I've never done anything with the event viewer since I bought the machine several years ago) Nothing seemed related to Cura, however. I tried to find a way to clear the event viewer so I could tell what was new when I re-tried the Cura stuff. I could not find any way to "clear" the event viewer. Dependency Walker said that VCRUNTIME.DLL had a problem with "__C_specific_handler" in Cura version 2.7 The problem with this is that Cura version 2.3 has the exact same problem in MSVCR100.DLL (__C_specific_handler) and that version works great. So I don't think that that's an actual problem? Thanks for the help guys. Keep it coming.

Nope, 64 bit. Windows 7 Home Premium Mine is 64 bit Windows 7 Home Premium Wife's is Windows 8.1 I finally got my wife's computer to accept version 2.7 No idea what I did differently the second time around but it went in and worked. Now I just need to get it on my computer. I will check this out and post if I find a log file. I'm ok with losing my Mark 2 stuff until I can get 2.7 running. I've re-done the mark 2 stuff so many times now it's second nature. I will check and see if those folders exist and delete them. (although I'm pretty sure I did this already once before) Thanks, I will check that. I will post if it shows something useful. Ick. It's an option, but ... just.... ick. (lol) I read some stuff about this when I was trying to download before. Any idea which DLL I need to fix? I tried running in compatibility modes too with no success. I will take a look and see what dependency walker is. I'm ok with doing a lot of stuff. But I refuse to mess with the registry.

So now I think I've tried everything I can think of. I even uninstalled my last 3 versions of C++ (2012, 2013, 2015) 64 bit only. (anyone think it has to do with the x86 [32bit] ? I installed Cura with AND without the Visual Studio option selected. I tried running it with AND without all the C++ redistributables. I'm beginning to think it doesn't have anything to do with the C++ stuff ??? It gives me the error message imediately upon clicking the program. I tried going to the program folder directly to start it. I tried right clicking "Run as administrator" with no different results. Anyone got any more ideas? Thank you. On a side note........ Version 2.3 works on my system without C++ 2012, 2013 or 2015. x64 I see it looks like it uses C++ 2010 Any chance I can make version 2.7 use 2010??

"Hmm weird, you could try this version: https://www.microsoft.com/en-us/download/details.aspx?id=30679 but that should just include an older version of the Visual C++ library files." Tried that with no luck.

Hmm weird, you could try this version: https://www.microsoft.com/en-us/download/details.aspx?id=30679 but that should just include an older version of the Visual C++ library files. In that link there are 3 options to choose from. Am I to select the last one that is called... "VSU4\vcredist_arm.exe" Or is the "VSU_4\vcredist_x64.exe" different than the one I tried earlier? Thank you for the help! EDIT = I see it is a totally different download. I will try and see what happens. Thanks.

Erm, no. Visual Basic != Visual C++. But the link is ok. Note that the Cura installer comes with the Visual C++ Redistributables, so they should be installed when installing Cura (unless you deselected the option to install them). Yep. Installed from the Link. Still no joy. Did not deselect anything from the list and made sure the option WAS checked when I installed it all those many times. (I actually thought I SHOULD try unchecking that option, but have not done that)

This usually means your visual basic distribution is corrupted. You could try to reinstall it manually: https://www.microsoft.com/en-us/download/details.aspx?id=52685 Thank you for the help. I tried this with no luck. "The application was unable to start correctly (0xc000007b). Click OK to close the application.

I figured this was not compatible with 15.0.6 so I went back to version 2.3 I made a breakthrough that I thought I should share with everyone. (Although not everyone will experience my issue I'm sure) After installing all the extra files for the Mark II upgrade and re-loading Cura. Go to Settings/Printer/Add Printer (just like the instructions say) When that window opens up, EXPAND THAT WINDOW! (drag in bigger with the mouse) My window showed all the printers in the list EXCEPT the last one in the list, because the window was not big enough. I continuously drug the sidebar down to be sure I saw the whole list, but THAT DID NOT DISPLAY THE LAST ITEM! I finally figured out I needed to drag the window bigger with the mouse (don't ask me what made me think of this) and BAM! there it WAS! Now, if I can only figure out what's going on with all the other versions of Cura that won't work on my system. (or my wife's system. Two completely different systems.) I look forward to hearing from anyone on this issue. No really...... Anyone.......

So I thought I would try it with the 15.04.6 version but I can't find where any of the files go for the Mark II upgrade. Is this not compatible with 15.04.6?

So Now I have 2.3.0 installed. Exit out of Cura. I placed all the necessary files in the proper folders for the Mark II upgrade. 1 file for the Definitions folder 2 files for the Extruders folder 2 files for the images folder (although I think the one that's titled "foo" is a junk file?) 1 file for scripts that goes to "plugins" "postprocessingplugin" "scripts" 4 files for the Variants folder. Re-start Cura and the Mark II option is NOT available. I removed ALL OTHER options out of the "definitions" folder and it gives me NO options for printers when Cura starts. So, for some reason, Cura is not recognizing the Mark II definition? I have re-booted. (many times) re-loaded Cura (many times) re-copied all files to folders (many times) I am getting so done with this dual extrusion upgrade nightmare. If I was on the clock for this upgrade, I would have paid for a new Ultimaker 3 by now. (sigh)

I just finished trying to download multiple versions and here is my results...... 15.04.6 works 2.3.0 works 2.3.1 works 2.4.0 doesn't work 2.5.0 doesn't work 2.6.0 doesn't work 2.6.2 doesn't work 2.7.0 doesn't work Is there something that changed from 2.3.1 to the newer versions that are causing issues with some systems?

I haven't heard from anyone about this so I went ahead and tried to download Cura 2.7 on my wife's laptop. Completely different system, and got the same type of message when trying to start Cura...... "The program can't start because VCRUNTIME140.dll is missing from your computer" At least now I know this isn't something on our end. Any thoughts? Anyone.........

I just finished converting my printer to the dual Mark II setup and was going to update my Cura as well. I deleted all the other Cura programs in my system and downloaded Cura 2.7 from the Ultimaker website. Took about 15 to 20 minutes to download but did it without any problems. Once downloaded, I clicked the .exe file to install it. It installed without a problem. Once installed, I clicked to open and that's when I get the error "The application was unable to start correctly (0xc000007b). Click OK to close the application" I have deleted and re-installed the exe file. I have gone through and deleted all other Cura files before re-installing. I have no idea what is going on here. I never had a problem with any other Cura programs. Is there somewhere I can download the older programs again, since they worked great for me? Thank you. My system is: Windows 7 Home Premium (service pack 1) Intel Core i7-3610QM CPU @ 2.30GHz 16 Gig Ram 64 bit - Jason EDIT -- When I go to Ultimaker in Google Chrome (Which I have never done before) the links mentioned above are now active. Just not in Firefox which is my everyday browser. So now the "view all versions" button works and I can try other versions. EDIT 2 -- Version 2.6.2 did not work either. EDIT 3 -- Version 15.04.6 WORKS EDIT 4 -- Version 2.3.0 WORKS

Thank you! - Jason

I did not see any other kit for the extended version, but I can email them to see for sure. I'm sure they will tell me it should fit fine since the motor doesn't "normally" sit at the top left corner of the back, therefore making it unreachable. I will look for wire similar to this and see what I can do in the meantime. Thanks so much for the quick response. - Jason
