VKB-SIM

I own one F14 grip. It loses DLC control axis (the axis locked up at the max reading)after each 1 hour playing averagely. I have to recalibrate it by using VKBDevCfg-C.exe. then it repeats again after a while. Any help is appreciated.

Run VKBDevCfg, select the device, click the Default button under the Tools tab, then click Yes at the configure popup and calibrate.

Thank you for the tip. I followed your instruction and it works for about 1 week. Then the problem shows up again with not losing DLC only but the most of buttons also this time. It's really annoying. Anyway to fix it permanently?

Is it on a Gladiator or Gunfighter base? And if Gunfighter, which model?

Thank you for the help. The base is Gunfighter with extension.
Gunfighter Mk.III 'F-14 Combat Edition'
Gunfighter Model:
Gunfighter Tabletop
Grip:
F-14 Combat Grip

Sounds like a connection issue - release the fastener securing the grip to the extension, then retighten the fastener while pressing down the grip for proper contact. Do the same with the extension to base connection.
