Console Commands

Command	Description
wire_expression2_model	Manually changes the expression's model
wire_expression2_reload	Reloads all E2 extensions, useful for debugging your own extensions. Keep in mind that client-side files will be taken from gmod's cache in multi-player mode.
wire_expression2_debug 0/1	Toggles debug mode, which shows info that might be useful for the developers. You need to do "wire_expression2_reload" after changing for this to have any effect.
wire_expression2_extension_enable	Enables the specified extension.
wire_expression2_extension_disable	Disables the specified extension.
wire_expression2_unlimited 0/1	Enables/disables performance limiting.

Note: Most E2 addons do not register themselves as extensions and thus cannot be turned on or off with the above commands. A notable exception is the Prop-core extension, which is disabled by default.

Also, you must run wire_expression2_reload in order for enabling/disabling extensions to take effect.
