Mining BOT wont undock

Welcome Markowich! :wave:

If Kaboonus was using the Sanderling App, you can run the script by setting up the App as described in the guide from How to Automate Mining Asteroids in EVE Online and then load the script by using the buttons Automate Something Else and Load Bot From Local File.
Then you can start the bot using the Start Bot Operation button.

Since you have already used Visual Studio, you might find the view under Enter Development Environment To Adapt This Bot familiar.
