Feature Request: Allow control of the print order of individual parts  

RE: Feature Request: Allow control of the print order of individual parts

This has already been done in the upcoming 2.2 release, you'll be able to reorder by changing the part order in the right hand panel.

RE: Feature Request: Allow control of the print order of individual parts

The latest versions of PrusaSlicer RC allow re-ordering of part printing sequence by dragging in the list at right. A final release should be coming soon.

Thank You!    

I'll move the Release Candidate!

RE: Feature Request: Allow control of the print order of individual parts

Sadly...   I don't think this feature works correctly in v2.2.     I have a multi-color part broken into different pieces.

I have the appropriate color assigned to each piece.   

And here is the thing...   I have two small cylinders defined and put at the top of the piece list.   Each cylinder is defined to be a different color.   The purpose is these cylinders should insure the filament is properly primed and flowing correctly before the pieces in the real print start getting printed.

It doesn't work.   The cylinders do NOT print first.

I would like to add the project file and the .STL file so you can load it up, slice it, and take a look the results.

But it says that would be a 'Security Violation'.   We have a 3D-Printer forum dedicated to Prusa's Slic3r and we can't attach project files or .STL files?   

I see in the code the concept of a 'Purge Towers'.   But even in Advanced mode, I can't find a way to turn those on.   Maybe somebody can offer some suggestions?

RE: Feature Request: Allow control of the print order of individual parts

Unless you're doing sequential printing, you have no control over what gets printed first within a layer. 

Do you have a multi-extruder printer? Wipe towers generally only are meant for single extruder MM setups. I think what you want instead is an ooze shield  (essentially a skirt that has the same height as the print, in addition to picking up ooze it also primes the next colour. 

IIRC there's a setting for that somewhere but I cannot recall where. But it might work to just make your skirt the same height as the print - it always gets printed first, but I seem to recall the way slicer works, it'll do a given colour for a layer, move to the next layer, finish that colour, do the toolchange, then the skirt, then finish the layer, and repeat. It might have changed, but is worth a try. 

RE: Feature Request: Allow control of the print order of individual parts

Thanks!   Yes...   I can try a skirt that goes all the way up.   That probably will do the trick.

RE: Feature Request: Allow control of the print order of individual parts

I just got home and checked. Under print settings->multiple extruders, you can check 'Ooze prevention'. (expert settings must be enabled) It'll both give you the skirt and drop the temp for the unused extruder.

You can also enable/play with the wipe tower on this page.

RE: Feature Request: Allow control of the print order of individual parts

Thank You for the help!    I'll give that a try and see how much it helps.   I already added a skirt, but dropping the idle nozzle's temperature will probably help some too.

RE: Feature Request: Allow control of the print order of individual parts

Heh... part of me got a kick out of the somewhat organic structures that form from the ooze picking up on the shield when I first messed with a dual-extruder printer. 🙂

Unfortunately, after many requests neither STL nor 3MF have been added to the whitelist of allowed filetypes without any explanation that I've see as to why not. The work-around that we have come up with is to zip the files together and upload the zip file. That works here.

RE: Feature Request: Allow control of the print order of individual parts

which is kind of silly in the case of 3MF, because 3MF is just a zip file with a renamed extension.

I think the whole "only zip files" goes way back to they days when viruses were propagated by sending executables in email. It's now one of those anachronisms that eats up a lot of time and does little to actually help security. There's no reason the server couldn't scan and zip the files if it's really a concern.

RE: Feature Request: Allow control of the print order of individual parts

Or from my perspective....   How can the developers duplicate the problems or issues we find if they don't have access to the source files that cause the issue to show up?    AND....    how in the world is attaching an .STL file a 'Security Violation' ?   There is nothing executable in a .STL file!   It is just data.   

The Prusa Slicer has a nice feature where I can save all the settings for the build plate as a project.    Wouldn't it make sense to let the developers have access to that so they can check out the situations that the users are seeing?    

RE: Feature Request: Allow control of the print order of individual parts

Bug reports are made over on github ( https://github.com/prusa3d/PrusaSlicer/issues for Slicer issues) rather than here.  While occasionally a dev will pop by and comment this is more a user to user forum. 

Github allow attaching files.  Its usual to attach the 3mf project file when creating a bug report, if you don't its one of the first things they request.
