Note the following From next versions tool parameters will be defined by tools library to add new tools you'll need:
- Open Tools library tab
- Select tools type (this only defines tool fields, you can add them after)
- A new group will be added that will contain tool definitions
- Fill in parameters with the text tool, if you do not understand something just do not change it

- You can add a number of tools, extension will choose topmost (in z order) tool in the active layer or in the whole scene if there's no tools definitions in the active layer.
Please tell us about your opinion about new interface.
By the way thanks for the bug report!
PS this bug fix should fix deep holes and high peaks but should not fix some bugs in c letter and "i"'s dot. May be subdivision that you've made is to much try smaller values. And about "as" letters do Path->Reverse for them.

PSSS I'm wondering that theres to votes for improving
Path to gcode what do you want to be improved?
