Yes I use a heat mat too..

The other main factor (besides hormones which you can help a little with) is local humidity which seems to be the main trigger... so I am now trying out hanging a cutting in a jar or cup that is ensured to have at least just a little humidity going on the underside of the cutting but that probably just happens from respiration.

Esp with a heating mat you may want to be careful with applying more direct moisture to the callus like with moist soil.

Edit:
The method of just suspending a small cutting in a jar with a humid piece of tissue in there seems to work. :) So far this may be my favorite method of rooting a cactus. It's really humid air that triggers the rooting and normally it is the underground humidity that achieves this, but that 'ground' is not actually needed.
