Ok I did a clean install with linuxcnc 2.10pre, rebuild my driver
I run linuxcnc in terminal and started from parity 0..2 and for each change i ran through the 4 options on my servo drive waited a min or two then went to next option but get the same on all options :
A and B signals still looks good :
// Lichuan A5 AC Servo Drive Driver
#define MAX_MSG_LEN 16 // may be increased if necessary to max 251
#define DEBUG 3
