Most likely trigger adjustment, if the trigger stopping screw is too far back that may be causing some problems. I had the same issue on my Vice and now it's doing better, your trigger should have a good range of motion, a super short trigger pull isn't always best. Just make sure it isn't passing too far past the activation point because that can burn out the microswitch in time. Other than that I'd reset the board to factory settings just to be safe, it's likely already there but if someone along the lines fiddled with it that can cause issues. Just hold the trigger back and turn on the gun this will get you into programming mode, then hold down the tourny lock button for 10 seconds to reset it, that should then give you the rainbow of lights indicating it's on factory settings.
If you still have trouble let me know.
it was the dwell it was set to 6 on the new OLED i put in instead of 8. i raised it back and it work fine. thanks yal
