7.07.2021
- some changes in data tools structure ('tool_type' to ['data']['tools_mill_job_type])
- some strings changes
4.07.2021
- optimized the Milling Plugin preferences
- added more preferences for v-shape tools in the Milling Plugin Preferences
- deactivated the automatic disable of the Cut Z parameter when selecting a v-shape tool in Milling Plugin
- in Milling Plugin added some protections against receiving signals from widgets without objectName set
- in Milling Plugin made sure that the Custom offset field is displayed only when it is needed (selected from Offset Type combobox)
- added some requirements asked by vispy v0.7.0
- if the generated Gcode is empty then the app will know and will not create a CNCJob object
- modified the Tool Table in Milling Plugin: now the tool type parameter is part of the Tool parameters and no longer in the Tool Table
- working on a Kosy CNC machine preprocessor file
