1 - Device model and version: VKB Gunfighter Mk I Base + VKB Extension + MCG Pro
2 - Controller Firmware version: BB_GF_MCGP_v1_94_B
3 - Number and type of springs used: Default, no changes.
4 - Type of cams used: Default, no changes.
5 - If VKB original software: VKBDevCfg-C v0.87.05

The question is in regards to joystick / pedals axes:

Hi Team,

I've noticed this behaviour getting worse on my MCG Pro + Extension + Gunfighter Mk I base for some time.
I had first seen it shortly after receiving my GF, and emailed about it. With a FW update, it only seemed to go away.

I've updated to the latest v1_94_B FW for the MCG Pro, and the problem is no better or worse. It is only affecting the X-Axis.
I've opened the GF's case to inspect for debris or other funky things in the housing, and haven't spotted anything that shouldn't be there. Visually, everything seems fine.

What can we do, gents?

Best Regards,
A Happy Customer

Shouldn't be difficult to fix, I think.
Remove the mechanism from the base and unplug the connectors of X-sensor. Don't just try to push them in with brute force hoping to restore contact: unplug and replug. No excessive force needed, just full out and full in.
Tell me if it worked.
Best Regards,

YOU'RE A WIZZARD 'ARRY!

It seems to have fixed that issue - I read the "MCG Pro Roll Axis Jumping" thread and suspected this had a chance of affecting my GF1 base as well, but not enough to go ahead and try that fix.
The problem was exactly that - a connector that was no longer fully seated. When I re-plugged the X-Sensor's cable into the socket, I noticed that the socket shifted on its pins. Possible dry joint?

On another note, I have a query regarding the smoothness of the movement on the X-Axis. I've noticed that despite the cams being clean and the X-Axis dry clutch being loose, I still have a fair amount of friction to overcome to move the stick on the X-Axis. It's enough to block out very fine movements, which isn't nice. On the other hand, the Y-Axis is buttery smooth.

What can I do to remove the friction on the X movement?

Cheers!

Try to swap the cams - the problem goes to the Y axis?

I wish that were so, but the problem exists even if I depress the X-cam away from the roller and move the stick.

Talking that scratching thing, pls take off the bottom cover and take a good picture of the inside. Pls allow some time to make it a really good picture (no hand-held camera, even no-shadow light, good sharpness, etc.) - as we need to look inside like the thing is sitting on our desk. Better take a couple of pics at a bit different angles. Don't be savvy on size/resolution.
Post them here, we will chew on it.

Hi Team,

After a stupid long time away, I've been able to return to the problem. Sorry, duty called :(

I've compiled a Google Photos album, hopefully it's some help for your team: photos.app.goo.gl/reCADyyR88nUhCxw7

I notice that the X-axis plastic buffer is not truly parallel with the X-axis. This seems to be a minor issue, though.
As a workaround, I loosened off the friction nut for the X-Axis all the way back, and the axis is properly smooth.

Happy to continue to wait, after all I wasn't able to get these images for you before I was sent away.

Cheers,
