Cura 3.1 released

http://ift.tt/2AA5glW Cura 3.1 – December 5, 2017New profilesProfile added for 0.25 mm print core.New print core profile added for 0.25 mm print core. This new print core has an extra fine nozzle width, which gives prints high definition and increased surface quality.Profile added for Breakaway material. New material profile added for Breakaway material, a dry post processing support material, which can be used for models with flat surface area overhangs.UI enhancementsFaster profile switching speed.Duplicating and removing a profile could take Ultimaker Cura quite some time, it now happens instantly.Faster printer selection. Removing a printer from the library is now instant. No more unresponsive screens.Faster processing speed. A 5 – 10 % speed increase when calculating normals, loading models, and slicing.Quick camera controls. New buttons have been added to the interface that can quickly reposition the camera view of the build plate.Lock model on platform. The move tool has a new option to lock a selected model to the platform. Once locked, it can not be moved in X, Y and Z directions.Layer view. The existing Layer view has been updated to include a virtual print head that simulates the printing strategy. This can be used to see the printing order of infill and walls, and if line ordering affects overhangs.Feedrate visualization. Feedrate visualization has been added to the Layer view. Speeds have corresponding colors, ranging from red to blue. Fast speeds (up to 250 mm/s) are represented by red (e.g. print head travels). Slower speeds (20 mm/s) are shown in blue, (e.g. the first layer of a print). Using this gives the user an idea of the print speeds per model part, allowing for better control over prints and more informed fabrication.Jogging. Jogging allows the printhead to be moved with on-screen controls. The Ultimaker 2+ and other RepRap printers can now be fully controlled from Ultimaker Cura when connected through USB. Each axis can be jogged in 0.1, 1, 10 and 100 mm increments.Large model loading. Loading large/detailed models and slicing them on a high resolution could affect the performance of Ultimaker Cura in previous releases. A new feature has been added which unloads the layer view when switching to solid mode, speeding Ultimaker Cura back up without losing your G-code/layer view information.Scripts folder. A scripts folder is now available in the Ultimaker Cura configuration folder. This folder can be loaded with post processing plugins scripts, which will automatically show in Ultimaker Cura. Contributed by fieldOfView.HP 3D Scan compatibility. HP 3D Scan Version 5.3.0 results can be directly exported to Ultimaker Cura application version 3.0.4 and laterOptimized workflow for crash reporting. Crash reports are automatically generated and allow the user, in case of a crash, to easily send their report with a description to developers.New slicing featuresFloating models enabled. In previous releases, models were dropped to the build plate when support was disabled. Models now float when the setting is enabled (even if creates an impossible-to-print situation). This can be used to stack separate models on top of each other.Slicing tolerance. A new setting that affects the intersect point to influence the dimensional accuracy for diagonal surfaces. The user can select the behaviour: ‘Inclusive’ makes gaps narrower, ‘Exclusive’ makes gaps wider, and ‘Middle’ is previous option, and also the fastest to process. When using ‘Middle’, the first layer will be taller by half of it’s height to compensate for the added half layer. This can be used to create better tolerances for test fit parts. Contributed by BagelOrb.Optimized zig zag patterns. Zig zag patterns now print more consistently. Lines now have a 5 micron tolerance in which they are printed any way, resulting in longer connected lines. Contributed by smartavionics.Aligned z-seam inner wall moves.Inner wall travel moves are aligned with the z-seam. This reduces the number of travel moves and reduces the chance of more unwanted seams.Relative positioning of infill patterns.Infill patterns are now positioned relative to the center of loaded models. Whenever you load the model, the infill is positioned the same. An offset can be applied to control the infill more precisely and adjust it to preference or strength. Contributed by smartavionics.Line resolution. Enables the user to specify the minimum allowed distance value between two points in G-code to create lower or higher resolution polygons.Custom mode changes. If profile settings have been modified in recommended mode under custom mode, a reset icon will appear to notify the user. Click the icon to show the changes that have been made, and revert back to the default profile settings.BugfixesFix for layer numbers being displayed incorrectly when switching between solid and layer modeFix for Cura Engine crashes during slicing if Optimize Wall Printing Order setting was enabledFix for uninstalling previous versions of Cura on Windows platformsFix for displaying visible settingsFix for importing legacy .ini filesPrevent skipping user agreement dialog by pressing escape http://ift.tt/2jhLeFm

I just bought an original Prusa kit and it’s terrible

So on everyone’s recommendation for absolute quality, I ordered an original Prusa Mk2S for my first printer over the Thanksgiving weekend. I received it yesterday and have been attempting to build it, and all I can say is WOW. Either their QA team drove off a cliff or everyone has cripplingly low expecations. First let’s start with the printed parts. I ordered a black one; maybe the orange is different, I don’t know – but at least half the parts have some kind of major defect. Most of them have compressed dimensions in the Z direction and exhibit substantial warping, to the point where they just don’t fit together correctly. The nut traps don’t fit the nuts at all, and most of the screw holes are so tight I had to turn the screws to get them through. There are artifacts everywhere, from melted corners to bundles of extruded strands hanging out. Four of the parts have already cracked between Z-layers, and before anyone says it, I wasn’t over-tightening them. The Y motor bracket cracked at the end-stop mount as soon as the screws were inserted, the X idler cracked around the pulley when I pushed the nut in, the anchor hook literally fell off the fan duct when I slipped it on and the shorter mounting screw for the extruder bound up and broke the extruder cover at the nut trap underneath while still sticking out ~3mm. I’m going to have to reprint basically all of the components before I can have confidence in the printer not simply falling apart. Last night I emailed Prusa about that, but since then I’ve managed to glue it mostly back together and get to electronics, where I find that BOTH of the fans provided have failed wiring. The extruder fan I saw right out of the box, with the positive wire pulled right out of the connector. There were maybe three or four total strands of wire on either piece so it wasn’t done well in the first place. So I soldered that back together, assembled the electronics – finding cut sheating on the extruder thermistor in the process – and got to self-test. That fails because the print fan won’t move, which I carefully go over and discover that the ground wire is disconnected inside the fan, behind the strain relief where it literally cannot have been connected at any point. I’m currently working on putting that back together and hopefully can salvage enough to make this thing actually print some worthwhile parts. Overall I feel I got ripped off for my $600, and essentially paid for a hard parts kit with some temporary bootstrapping parts rather than a complete printer. I can’t recommend this thing to anyone else, and the frustration and feeling of being cheated have fully ruined the enthusiasm I had for this project just a couple of days ago. If it didn’t cost so much more to ship back to Prague I’d be returning this in whole and buying a CR-10 or a Pegasus. http://ift.tt/2jjOFv4

I just came across this guy and I’m wondering why I haven’t heard more about him. He makes printer upgrade tutorials and refuses to give the parts list to anyone who isn’t a Patreon sub. He also has an edited version of Marlin which he puts behind the same $5 paywall. Why is this okay?

Why have my prints started coming out like this? I’ve been battling this for over a month now and I’ve replaced nearly every part in my printer, AND sent it in for repair. It’s been making me want to quit the hobby entirely. Maker Select V2 with brand new microswiss all metal hot end
