If this is the first time use the Calmotion with the Fadal. Make sure the default baud setting on the Calmotion is also available on the Fadal. Go to SETP, the baud rate 38400 must be available in the parameter list to use the Calmotion out of the box. If the Fadal max baud rate is 9600, the Calmotion INI file must be reconfigured to use a lower baud rate. See user manual how to make a INI file for the product you have.
Make sure the SETP parameter CMD MENU or COMMAND MENUS is set to OFF or SPACE, do not use the setting of ON. If the parameter does not exist in the SETP, then ignore.
Make sure you enter the CD,# and then when back to ENTER NEXT COMMAND press only the + this will display the HELP menu. This is a great first step:
CD,10<enter>
+
The help menu will display.
To avoid Windows adding extra file extensions, make sure the Folder Option "Hide extensions for known file types" is unchecked.
For the USBCNC-FAD products the USBCNC.INI file is used. See below for an example. The CNC=38400 is for CD,10. Change to CNC=9600 to use the Calmotion USBCNC-Fad with the CD,8 command.
For LANCNC-FAD or LANUSB-FAD products use the file LANCNC.INI
Use Windows Notepad to edit the file. Make sure the file is saved exactly as shown. The File Explorer option to view actual file extensions might need to be enabled.
