Topic: 6614: SMM not responding error

Technote 185 Date: February 2005 Product: Free Form Machining (SMM)  Version: Pre-version v12

The pre-version 12 SMM will fail with path/file names that have spaces in them ('Program Files' for example). If you have Custom installed SmartCAM in a location such as this, please uninstall and use a Typical install.

Be sure to install logged in as the user. See page 5 of your installation guide and this technical bulletin (section 1.7 particularly):
Technote.155
User permissions are critical to a SmartCAM installation.

Check the [SMM] section of your ffm.ini file in the "USER_HOME" directory. Be sure that the path specified by the WorkDir variable is where the FFM and SMM executables are located and that the user has full permissions to this directory.

Check the ffm.ini pdelib_tmp variable under [Paths] and that this directory exists. This is a temporary storage directory and it is good to delete everything in it from time to time.
