<<You'd need a proper dedicated counter and some way of reading
it I guess ... and even then, what do you do if they are in error? All I can
see to do with a stepper is abort the program, recovery could be
difficult.>>
There is no reason the next gecko 2003 couldn't support this. the hardware
FPGA architecture will give enough power for 20 axis or more... in only 1
cost effective chip (about 5$ for cheaper ones, in the Altera Cyclone family
for example). The nice things in these circuits is we can have dedicated
DSPs modules, 32 bits controlers with C or assembler code, and wired logics
in the same chip. All what we need for a sophisticated pulse engine with
closed loop feedback at a low cost.
<<producing machining strategies is the job of an external
application ... >>
These applications are professional ones isn't it ? More they need a
specific (serial ?) interfacing with professional probes. Do you know a
hobbist priced one for craftsman ?
