Up to 16 of each I've seen someplace. 4 is the default though. But, I need to pass 2 floats to make what I want to do, works right. And I'll need to make sure that variable 00 never gets mixed with variable 01 by the sharing of a single #5399 placeholder for the gcode to retrieve and use. I'm sure there is a reason for the #5399, but so far I don't recall hearing it.
