No, it's not my age that's the problem, it's my machine.
I've set up turbo on my desktop, and can open the programme in dos ok.
At present it doesn't recognise my mouse, even though another dos based cnc programme does(Supercam), but I'm assuming that's another problem to be sorted out later.
(The Supercam prog works ok and successfully drives the m/c.)
A friend has sent me a config.ini file based on my m/c setup, and that is in the file ok, and seems to have set the step size/limits/ etc., as expected.
However, the keyboard arrow keys produce no effect whatever.
I've printed out the whole 97+ pages of the manual, and read it numerous times, but can find no clue there.
Any suggestions welcomed.
