I am a little old school, in that I use a piece of paper under my tool as a feeler guage, to set the Z zero position. I use a mini wireless keyboard as my "pendant" to jog the machine around. I hit the pgup pgdown buttons and the machine jogs the Z axis at the rapid rate. This works great to get me close. I then mapped CTRL-PGDWN to jog at the incremental rate. Whatever rate was last selected. All good up to this point. This is where I am looking for some help. I would like to set CTRL-PGDWN to jog Z at a rate of 0.001 and have ALT-PGDWN jog Z at a rate of 0.010. I am having trouble figuring out how to do this or even how to approach it. Is it a key mappable thing or do I need to write some code?
