* 15.10: (39 commits) Remove unused import in StartSliceJob conforming to code style fix typo's.. Adjust initial view to be slightly from the side uses a different method to check whether a machine name excists Sets the languageComboBox to the default language Remove per-group settings for now Make sure to send all settings when an object overrides the profile Properly emit writeStarted in RemovableDriveOutputDevice Add xy_offset setting to list of settings that trigger a disallowed area update Properly trigger a reslice when the active instance is changed Wizardpages without hack Only hides the window when there are no more pages Only add layer data node after all processing Also account for "xy_offset" setting for the disallowed areas JSON: workaround for stutter in spiralize vase: set travel speed to printing speed Adds a color for the error-messages Shows an error message when a user tries to add a printer with a name that already excists. JSON: support bottom stair step height defaults changed so that the bottom distance to the model isn't violated too much Try to use Protobuf CPP implementation if it is available ...

General interface for Isp based AVR programmers.
|
|
The ISP AVR programmer can load firmware into AVR chips. Which are commonly used on 3D printers.
|
|
|
|
Needs to be subclassed to support different programmers.
|
|
Currently only the stk500v2 subclass exists.
|
|
This is a python 3 conversion of the code created by David Braam for the Cura project.
