I have delta with version 1.0.3dev
1. What is new in version 1.0.4dev, I cant find changle log for version 1.0.4dev ?
2: Is it OK to download version 1.0.4dev and just replace configuration.h with one
from version 1.0.3 dev
In config tool you can upload old config and download new. If you have not used config tool you need to compare options.
Interesting new functions are emergency parser and host rescue system to continue printer over repetier-server in case of power failure/disconnection. Contains also many smaller fixes and improved advance, also with bowden advance is not really useful.
