HI Hood, Yes a TOM button , a THC on/off button, Zero all button , and it depends on what you setup for teh functions for Plasma. It can run from a simple cutter or a complex cutter with many plasma functions and adjustments both to teh software and hardware.
An example of a handy set of buttons would be run extents , a routine to dry run teh outside contour to verify the part fits the material. Then there is offset right and offset up, routines to offset the part to the right side extents so that you can cut a second part quickly and the OffsetUP which does the same only in the up direction.
Then there is teh G68 part rotate.
There are a lot of interesting and time saveing functions so it just depends on what you want or need from Plasma.
