Release: Slic3r Prusa Edition 1.42.0-alpha4:

New features:
-> For the Prusa3D printers, Slic3r PE now displays three dimensional print bed models.
-> Implemented sharper rendering of the print bed bitmaps thanks to anisotropic rendering of the print bed textures.
-> When selecting a component, there is now a small mouse movement hysteresis before the newly selected object starts to move.
-> Tooltips on toolbars are now shown even if the buttons are disabled, and the tooltips contain the keyboard short cuts.
-> It is now possible to detach instance or multiple instances into independent objects from a context menu in the 3D scene, from the instance context menu in the object panel, and by dragging the instance inside the object panel to an empty space #1688.
-> In the advanced & expert mode, we introduced an option to add a fixed selected set of frequently overridden object parameters with a single click. For example, the overrides for number of perimeters + number of top / bottom layers may be added to the object parameters from the object's top context menu with one action.
-> We have changed the "advanced" user mode to show the object list, however the context menus in the "advanced" mode are slightly simplified compared to the "expert mode". We recommend to use the "advanced" mode for every day printing to the expert users, and to use the "expert" mode just for printer parameter tuning.
-> In SLA mode, the "enable pad", "enable supports" check boxes are now available at the side bar.

General fixes:
-> Fixed the variable layer height editing #1499, #1610.
-> Generic subparts (modifiers, support blockers / enforcers) are now placed initially at one of the bottom corners of the world bounding box of the transformed currently selected instance, so that the newly added subparts become pickable #1517.
-> Fixed missing layers in sliced objects. This was a regression error due to missing merges from 1.41.2 (stable) to the current 1.42.0-alpha1 #1562, #1592, #1614, #1633, #1650, #1711
-> Fixed closing of the "About" dialog by clicking on the logo. The "About" and "Firmware Updater" dialogs now close on escape key #1606.
-> Extended the resolution of the side panel object manipulation numeric input fields to two digits after the decimal point #1619.
-> Fixed an old but rare extra extrusion occurring for a single perimeter, no infill prints with wipe after retract enabled #1631.
-> Fixed incorrect capture of the accelerator key "?" bound to the "Keyboard Shortcuts Help Dialog". The "?" key was captured globally, therefore it was impossible to enter "?" into the text fields. Now the "?" key is captured in the 3D scene only #1638.
-> Fixed incorrect placement of modifier meshes after reloading from a 3mf file #1640.
-> Fixed update of the object manipulation side bar after an object is deleted and another object is loaded #1645.
-> Fixed endless recursion after switching into the vase mode, where the "Shall I adjust the depending parameters" opens over and over #1649.
-> Fixed a crash after changing print values with some layer color changes defined #1658.
-> Re-implemented post processing scripts on Windows. Slic3r will run batch files (with the .bat extension) with the cmd.exe interpreter, it will run perl scripts (with the .pl extension) with the perl.exe interpreter searched for in the Slic3r install directory. As we are no more distributing Perl with Slic3r, you will likely need to install our precompiled Perl #1666 #1714.
-> Fixed zooming of the camera to print bed on application start and when switching printer profiles #1671.
-> Improved user interface responsiveness by caching the status of "object consists of multiple parts, therefore it is splittable".
-> Updated localization pod files from the current source code. Contributors are welcome to help with the translation, though please be aware, that some texts may still change.
-> Added menu accelerator keys (those letters, that are displayed as underscored in menus). These letters shall be unique in each menu, please keep that in mind when localizing menus.

Fixes for Apple macOS:
-> Implemented high resolution (Retina) rendering of the 3D scene #97.
-> Disabled smart substitutions in the parameter input fields #830 and in OctoPrint input field #1678.
-> Fixed restoring of the Slic3r window after being minimized #129, #925.
-> Fixed main window persistence (restore window at its previous position and size). If the restored window is out of the current set of displays, it is moved to the primary display #493, #1272.
-> Fixed compilation issues (deployment target was incorrect) on Mac #1421.
-> Convinced OSX to not replace Slic3r's Window menu with the operating system default menu. This issue fixed missing "OctoPrint upload queue" menu item in the Window menu.
-> Fixed a bug, where the actions, that should have happened on closing of an application (storing of modified profiles, storing of window positions) would not happen if the application was closed with Cmd-Q key combination.

Known issues (will be fixed in the next release
->Synchronization between Objects List and Object Manipulation fields is broken. If the object list gets focus, it reverts the changes entered into the Object Manipulation box.
-> Rotation using Object Manipulation fields is broken.

Do you plan introduce a perspective view?
Please very much?????!!!!!!! 😀 😀 😀 😀 😀 😀 😀

+1 I want this too!!

This is one of the things I miss most from CURA.. I just can't visualize the object as well in Slic3r as the Isometric view just doesn't look right.

I saw some months back that this feature has been added in Slic3r so it shouldn't be that hard to enable it in the Prusa edition.

Re: Slic3r Prusa Edition 1.42.0-alpha4

I see changing % is messed up again in alpha 4. work around seems to be after changing all 3 % to click on position X. thats gonna be a pain in the arze to use 😀

think it has something to do with how it refreshes the screen data while updating numbers

reposted from the alpha 3 page, don't want it to get forgotten

I have a Prusa,therefore I research.

Re: Slic3r Prusa Edition 1.42.0-alpha4

-> For the Prusa3D printers, Slic3r PE now displays three dimensional print bed models.
Heatbed model does not show up for my (user defined) MK2.5 printer, but it does when I use the MK3 printer (system) preset.
Is this a bug in the software - or a bug in my settings?

It's a bug in the settings - for my MK2.5 I need to add following line:
inherits = Original Prusa i3 MK2.5

Now the visualization is as it should be!

Different folks like different sorts of 3d projection and for many to relates to how you learned to draw in class
I have been a lifelong fan of Trimetric projection but then I learned mechanical drawing in the early 1960s

https://en.wikipedia.org/wiki/Axonometric_projection#Three_types
Trimetric projection, the direction of viewing is such that all of the three axes of space appear unequally foreshortened. The scale along each of the three axes and the angles among them are determined separately as dictated by the angle of viewing. Dimensional approximations in trimetric drawings are common and trimetric perspective is seldom used in technical drawings.

Which of those 3 does Slic3r currently use? In Slic3r, the background is wider than the foreground (does that even make sense). Perhaps a picture shows it better:

This doen't look like any of the examples. I assumed the left/right sides would be parallel (is that Isometric?), so the background/foreground were the same.. But the mode today seems to be the opposite of what I would expect.... I am not sure what value having a view as we have today gives?

What I would like is a perspective view like Cura, where the side edges converge to a point in the distance.. Like this:

I know that many people will have different preferences, so I would like to see an option until Config so you can switch between the modes...

Re: Slic3r Prusa Edition 1.42.0-alpha4

Right now we have isometric go to the view menu and select ISO
I agree a way for folks to select their preferred view would be nice and having it be a configuring preference would be nice.

I have to admit is not a make or break sort of option as for the vast majority of folks that never did manual mechanical drawing (folks less than 60 or 65 I would guess as CAD drawing started to be introduced in engineering schools about 40 or 50 years ago) Isometric is what they learned

this is a simple hoop in ISO

Loading a multi-part object for MMU is broken. It's already been noted and should be fixed in the next release.

Really? So they broke a fundamental feature as this? What is broken about it, and is there a workaround?

Re: Slic3r Prusa Edition 1.42.0-alpha4

for fun I added color using a modifier part with extruder picks.

100% colored using slicer 😀 (alpha 4)

Re: Slic3r Prusa Edition 1.42.0-alpha4

I am having problems with the cut command it defaults to 56.60 z I select keep upper part and try to change the 56.60 to 76.0 but as soon as I enter it it snaps back to 56.6
I tried unlocking the object manipulation pane where the Z was also defaulted to 56.6 but changing it even unlocked would not stay changed long enough to perform the cut

is the STL

what am I missing?
Looks like a bug you have to grab an drag the layer handle then you select the layer cut icon no direct entry of the precise z for the cut is enabled and dragging only gets me to about ± 0.1mm of the level I want.

Re: Slic3r Prusa Edition 1.42.0-alpha4

ive been able to cut, might have just gotten lucky.

I would bet almost any part when you type in numbers might act up.
seems to be the bigger issue.

try entering the number you want, click on say the save lower part twice (so it puts it back). then cut. I bet money that would work.

Re: Slic3r Prusa Edition 1.42.0-alpha4

Yes You can cut it. I di try your method but I could not get the entry box for z level in the cut window to take my precise entry I could and did do it by moving the cut handle that appears when you select the cut icon. I am printing it right now but I could only get to within about 0.26 mm of the desired level for the cut .It is printing now and I will just sand it down to what I need to fit the lower 2/3 of the part which failed with a PETG snot glop causing crash recovery a few times when I was out at the market doing my weekly shopping.... When I returned I stopped it and cleaned the mess of the failure level off of the now top of the bottom of the part... I will glue it up and paint it up and only you and I will know about it 😉

🙁 I will go out of my way to mess with the cut. they might even have it fixed already for the next version who knows

Loading a multi part stl produces something like this. No workaround that I'm aware of. That's the joy of alpha software.
