#8.DESIGN OF AN 8 OUTPUT COMPARATOR

#8.1 Pete Gruendeman

Reading #10.EDM Noise on the LinuxCNC Mailing Lists. on LinuxCNC on Debian, we read his way of programming the loop of his detector:
Read the gap voltage;
If/ gap voltage > 3/4 Voc, move ahead;
If/ gap voltage > 3/4 Voc && < 2/3 Voc, stay put;
If/ gap voltage < 2/3 Voc, backup;
repeat
This might mean on a 80VDC Supply a gap between 66% and 75% or between 53.3VDC and 60VDC or only 6.7V difference.
We suppose this is a bit a rough approach and meant for a feed.enable button to go on or off.
We start to detect 8 gap voltages for MUX8 on a gap level of 12VDC giving an adaptive speed to the WEDM.
