Have used Vectric with Mach3 for many years without problems. Recently gcode would not download. This is a text file and noticed the file heading  where the gcode text file was to go was *tap. Changed this to all files *txt*   and download then worked fine. Upon moving to the next project the * tap returned. How do I permanently get the file type to return permanently to text. I have always manually downloaded the gcode text file. Dowmload direct to machine has never worked, how is this feature set up.

Its a little quirk in so far as the load file type is stored in your <profile> .xml file which is only updated when Mach3 is shut down.

Set 'File of type' to (*.txt) then load your .txt file. Shutdown then re-open Mach3. It should now be set for loading *.txt files.

(there are probably other ways of doing this but one method is as good as the other)

Tweakie.
