Hello everyone!

 

I’m having a problem with my analog plunger ever since I had to replace my controller board due to a defect (upgrading from an early PinControl 1 to the current PinControl 1 version 5.0).

 

The movement of the virtual plunger is no longer linear—a 1:1 match with the physical plunger—but rather exponential across its range of motion. This means that for the first 1–2 cm, the virtual plunger moves more slowly than the physical one; it then moves linearly for a short stretch, and subsequently moves faster than the physical one. The interesting thing is that this effect occurs exclusively within VPX. When I check the axis movement in the joystick calibration settings, everything appears perfectly linear. I’ve already experimented with various plunger settings in VPX but haven't been able to find anything that resolves this issue.

 

So, the controller itself is functioning correctly; however, something—presumably related to the controller swap—is causing this specific behavior within VPX.

 

I'm a bit lost. Does anyone have any ideas?

Just this:

Important: (In Windows Control-Panel) do not calibrate!

The Game Controllers control panel has a "Calibrate" button under the Settings tab that many people see and think it would be a good idea to click. Don't! This particular calibration process is designed for real physical joysticks only. It's unsuitable for plunger/nudge devices and it'll make your device act erratically. If you clicked the Calibrate button at some point thinking it would improve matters, you should undo that, by returning to the Settings tab and clicking "Reset to default". That will erase the troublesome calibration data and restore normal operation. (This advice applies to the Pinscape Controller and most of the other nudge devices I know about, but there might be exceptions. If your device's owner's manual tells you to use the Windows joystick calibration despite what I just said, go with the owner's manual's advice.)

Your controller board software should have the plunger calibrate.
