Slic3r Prusa Edition Slic3r 1.38.5 - Prusa Edition
Summary:
This is the Slic3r 1.38.5 - Prusa Edition release. This is a release candidate, mostly polishing the previous beta.
If you happened to install the printer profiles bundled with the 1.38.4 beta, we recommend you to update the printer profiles by running the Configration Wizard from the Help menu.
Print / Filament / Printer profile compatibility
Starting with Slic3r PE 1.38.2, the selection of print and filament profiles may be limited by explicitely enumerating the printer profiles, with which the print or filament profile is compatible. However, we found such a simple enumeration limiting. Namely, a duplicated printer profile does not inherit the print and filament compatibility. To make the concept of compatible printers more flexible, we introduced a compatible printers condition. The condition accepts the same boolean expression syntax as the G-code macro processor, and it may reference any configuration value of the active printer profile.
Even more flexibility is achieved by integrating regular expressions into the G-code macro processor and into the compatible printers condition. The new regular expression syntax is inspired by Perl: The expression `variable=~/regex/ returns true if the regular expression is matched, variable!~/regex/ returns true, if the regular expression is not matched. The new regular expressions are used by the Prusa3D Slic3r profiles to match keywords in the printer notes.
For example, a keyword PRINTERHASBOWDEN is stored inside the printer notes of the MK2 Multi Material printer profiles, and an expression printernotes=~/.PRINTERHAS_BOWDEN./` is used inside the filament start G-code to control the linear advance value.
This release contains the following improvements:
- The G-code macro processor has been extended with the usual ,=,or,and,||,&& operators.
- The configuration wizard now offers a new "Reset user profile, install from scratch" on the first page, if the wizard is opened from the Help menu. This allows one to reinstall the bundled printer profile cleanly.
This release contains the following bug fixes:
- Fixed a regression issue from 1.37.2, where Slic3r crashed when a G-code was sent to OctoPrint with non-ASCII characters in the file name #597.
- Fixed a wipe tower regression issue from 1.38.3 #642.
- Fixed a regression issue from 1.38.2, where the "modified" flag at the active profile did not update. This issue was specific to OSX #632.
- Fixed a bug in the new volumetric speed hint, which ignored the first layer speed #641.
- Fixed a regression issue from 1.38.2, where Slic3r crashed when the "- default - " preset was modified #643.
