Firing Button Issue

[Logan314]

In my DNA mod the firing button does not always fire when pressed, it is also randomly locking without pressint the firing button 5 times in succession. Any insight as to why this may be occuring?

Usually that is a button that fights tight in the case or gets jammed or finally is too tight against the tactile switch.

It has worked flawlessly for the 2 months since i built it and just over the last few days has it been acting up. Maybe i will take it apart tonight and check it all out.

Perhaps those small membranes inside your tactile needs a cleanse or replacement, tactiles have more cycles than vandalswitches but check it as you can open them but gently

Or the display ribbon cable has moved to the point where it is interfering.

I have the bigger size 3d print box like that and had to adjust the board screws a little to keep the buttons from firing......try loosening up the top 2 board screws a little......also the battery fits very tight in there sometimes pushing down on the board to much.....like the others above have said check to make sure your buttons move freely in and out there respective holes and sand them if need be
