"Hello Focus Attack,.... I am having a problem with my GT-O Sanwa restrictor(http://www.focusattack.com/jlf-gt-o-circle-restrictor-plate-insert-for-sanwa-jlf-joystick/) I ordered from you guys. When I installed the 360 degree restrictor gate on to my stick, I noticed an issue. All directions work perfectly however, all four diagonal directions are not. They do not register. I am only able to move up, down, left and right. After many attempts of of trying to fix it, there has been no solution."
When using the GT-O for a brand new JLF TP-MA pcb the gate should work fine but after a little bit of use, switching to the circular gate could be met with this type of situation as the switches lose a little spring. The two solutions would be to switch to replace the microswitches or get a Kowal 1mm oversized actuator (http://www.focusattack.com/kowal-1mm-oversize-actuator-for-sanwa-jlf-series-joystick/). This should restore the activation of the switches and can assist with better execution of joystick movements.
"After putting on the actuator, all directions now register correctly"
