RE: PrusaSlicer

Also as a slight workaround to the brim on a single part problem what I do is as a modifier, make it 1 layer thick and stick it below the part.  Instant large 'mouse ears' to give tall thin things extra surface area.  Then you can just remove the extra just like a brim.

Great tip! I'd previously used "dimes" to create the mouse ears on corners, but hadn't thought to use a modifier. Much simpler and more flexible.

Anyone know what "filament_type[0]" should be changed to to get the filament name instead of type?

You can use [filament_settings_id] to get the full filament profile name. If you match your profile names to the filament product names, this might work.

Prusa Slicer 2.0 is a hit here.  Nice improvements.

Support for the OctoPrint Cancel Objects plug-in was announced as part of Prusa Slicer, but I am having some difficulty getting it to work.  Multiple objects on the bed in Prusa Slicer (tried both Copy/Paste individual and +Instances).  Plug-in is enabled in Octoprint.  When the Cancel Objects menu is selected in OctoPrint after the object is loaded and/or printing, the message displayed is:

Object list populated when GCode file is loaded.

Is there a configuration in Prusa Slicer that needs to be set in order to turn on this functionality?

Thanks in advance for any help.

RE: PrusaSlicer: "Copying of the temporary G-code ... failed" error message

Symptom:

Suddenly I began encountering  the following error message whenever I tried to save G-code. "PrusaSlicer has encountered an error Copying of the temporary G-code to the output G-code failed."  

Dead end approach: Since I had been creating various flavors of custom G-code, I spent a lot of time searching for errors in my new code. Even deleting the user presets I had created didn't help.

Solution: It turned out a gremlin had moved he little "locked" slider  on the SD card where I was trying to save my output G-code file.  After I moved the slider to "unlocked" everything worked correctly.

Perhaps the error handling could be corrected to test for this kind of error and generate a more specific message. For example: "the output G-code could not be saved at the designated location."

[...] Confusing there is you get the idea that you can configure each instance separately, but its only the position that is separate. Things like rotation and scale are still shared.  'sweird! I would personally split the position from the other parameters and not show those in the instances (main object is responsible for orientation, scale and modifiers, instances for the position on the plate). There is the "Set as separated object" there that allows you to split and separately transform them if it's needed.

This linking only happens if you copy an STL into PrusaSlicer (PS) and increase copies. If you drag in a 2nd copy of the STL, it is completely independent for scaling and surface placement.

I know, you can also split them by using the "Set as separated object" functionality. My point is that the fact that those settings are shown there is confusing UX/UI wise. I wasn't suggesting there's no way around it 🙂

I haven't played around with that myself (probably due to me not having Octoprint set up...), but I think I stumbled across the setting in PrusaSlicer that you might need:

As you should (hopefully) see in the screenshot, it is an Advanced mode setting (the yellow indicator) in the Print Settings tab, Output options screen, called Label Objects. Note the incompatibilities in the hover-text... I'm not sure if those incompatibilities are in the slicer algorithms in PS, or if Octoprint gets confused if commands for both are in the gcode. Nor is there an indication of the failure mode if this setting is made with the indicated incompatible settings. (Hopefully PS alerts you when you select that setting and there is a conflict, similar to how PS acts if you select 100% infill with any infill pattern other than rectilinear.)

RE: PrusaSlicer

I miss being able to rotate the  model freely as I used this a lot to get my extrusion thicknesses and layer heights just right for good prints without issues, now I can't check every orientation and angle as before to make sure I have no issues, at least not as easily as before.

I can rotate the object freely in 2.0, simply using the rotation gadget on the left side of the screen or by entering the rotation values manually. What are you missing exactly?

Do you mean rotate the object in the build area to change the print orientation, or rotate the camera around the build volume to look at the object in a single print orientation from different angles?

@vojtech-p6 seems to be answering the question of rotating the object with respect to the build area, so I'll tackle the rotating the camera question.

Holding down the left mouse button and moving the mouse does this for me on my Win10 system(s). But, I have to make sure I click on an empty part of the build area in the 3D editor view. If I click on the an actual object I will start just moving that object around the build platform (this can be problematic if I want to rotate my view while zoomed in such that the object completely fills the view). But if I'm in the preview view the LMB will rotate the camera no matter where I click. If I have "Detect bridging perimeters" checked (advanced-mode setting in the Print Settings tab) and the preview view mode is "Feature type", then all my bridging and overhanging perimeter sections show in dark blue, which for me is a good contrast to the external perimeter orange color.

RE: PrusaSlicer

Thanks Sembarazu, this is what I was after, but for some reason it does not seem to be working for me.

I will check my logitech mouse settings (Maybe a conflicting profile) and unplug my spacemouse to see if maybe it is something with these causing the move camera function to not work.

I too check for bridging and perimeters and supporting of bridging to make sure the slicer is not trying to print into thin air. It's surprising how often it actually try's to, and I have to alter infill rotation or type and or perimeter thicknesses or something else to get a good print first time.

I had a poor print last night of a part for work because I could not check it thoroughly whist using layer modifiers, but for what it was for, the hole did not really matter.

RE: PrusaSlicer

All working 😀 

Must have been something this end, been meaning to update some drivers and software for my PC hardware anyway, did a load of updates and general PC de-cluttering programs etc and now Prusa Slicer 2 all works as it should.

There is the "Set as separated object" there that allows you to split and separately transform them if it's needed.

The instances are synchronized as they may share support modifiers, which are sensitive to rotation of the object towards the print bed. The synchronization of rotations and scaling is even more important to the SLA prints, where the supports are mandatory most of the time.

The PrusaSlicer 2.1 will suggest "Is (path to your file) locked?"

RE: PrusaSlicer

But I can modify the orientation of modifiers and not turn the part ... and I'd expect it to be that way.  So some thought is needed on use cases before jumping into implementation.

Gcode generated from the current and previous versions of Prusa slicer has all the settings at the end of the gcode already.  If you open the gcode in a text editor and scroll to the bottom of the listing you will see it all there.  It doesnt have the models, modifiers etc though so for those simply save the project as a 3mf file, that way you can easily go back later and adjust things.

Neophyl/All,

As a bonus, should you wish to IMPORT the config from a previously generated GCODE you can change the first line of the GCODE to "Slic3r" from "PursaSlicer".  It will not load in the model etc.

Change the first line from:

; generated by PrusaSlicer 2.0.0+win64 on 2019-06-10 at 07:54:24

TO:

; generated by Slic3r 2.0.0+win64 on 2019-06-10 at 07:54:24

Your BEST bet is to save ALL of you models as 3MF files. That allows you to save your models and the configurations.  That's the main reason that Prusa is asking people to put their 3MF/AMF files on the website.  It helps others learn from settings of the original developer of a model.  then when you change configs save a NEW 3MF/AMF file and the associated GCODE will be named the same.

RE: PrusaSlicer

I do save all my files as 3mf 🙂  Got into that habit long ago after watching one of Chris W's  youtube videos.

That was meant as an answer to Milo-Vs question, just above your answer. 😉  At least a workaround for loading the GCODE into PS for the configs.
