That error is actually part of the sefault TurboCNC setup. You can ignore it. What you need to do is setup for your HobbyCNC board.
I run a HobbyCNC board with TurboCNC 4.01. Works great. Don't get discouraged. I am attaching a PDF that shows some basic settings and I will get my TurboCNC INI file from my computer tonight and upload here for you.
You will have to change some settings to match your leadscrew ratios, inches per minute travel, etc. However, it will be a start.
