The Axis UI increments the spindle speed in fixed increments of 100rpm
(Code here from command.c)
case EMCMOT_SPINDLE_INCREASE:
rtapi_print_msg(RTAPI_MSG_DBG, "SPINDLE_INCREASE");
if (emcmotStatus->spindle.speed > 0) {
emcmotStatus->spindle.speed += 100; //FIXME - make the step a
HAL parameter
} else if (emcmotStatus->spindle.speed < 0) {
emcmotStatus->spindle.speed -= 100;
}
break;
You have an unusually low spindle speed range (0 to 100 rpm) so the
very first "increment" press takes you straight to your max spindle
speed of 100rpm.
Note that even here it is acknowledged in the code that this isn't
quite right...
