Leopold FC660m - new case, but strange outputs

[THSdrummer]

I finally received my aluminum case for my Leopold FC660m (ordered off of Massdrop). I performed a case surgery on my Leopold FC660m and moved the PCB/plate to the new case, taking care to remove the keys before and put them on at the end. Unfortunately, my keyboard now puts out weird outputs. I played around with the switches on the back, but to no avail. The keyboard will type slowly, but normal and then the cursor will jump to the start. Occasionally the caps lock will turn on or off, but does not function (LED or perform the intended task) when I press it. Sometimes the keyboard will continuously input two keys (i.e. "FHFHFHFHFHFHFHFHFHFH") while I'm typing. The input doesn't stop until I hit a different key. The left control/windows button doesn't seem to be working either.

My questions are:
- Did I just screw up my Leopold FC660m?
- How do I get it back to normal?
- Is there any hope to restore my Leopold FC660m?









Thanks so much!

P.S. sorry for switching inputs/outputs around. The keyboard outputs strange things, despite my input.

Is the metal case hitting electrical contacts?

[Bucake]

^ that.


first thing i would've tried is just remove the case and see if that fixes it.

Install a soft non conductor material sheet under the PCB to avoid short circuits. It could even be a thick piece of paper trimmed to fit exactly. Also, the USB connector should not be in contact with the Aluminum case.

Sheisse, guys. Didn't even think about it shorting on the metal case. I'll add something inside to try and insulate it. As for the USB touching the case, it's a really snug fit. I'm not sure I could add anything between it and the case to insulate it. Should I sand it back? That sounds scary, but perhaps it's the only way.

Take it one step at a time. Start with insulating the bottom of the PCB from the case. If that works, job done. If not, then you'll have to go deeper and perhaps look into making a modification around the USB port.

No, no, no sand it. Just adjust the position of the PCB to keep the USB connector centered within the USB hole of the case. You may add extra insulation material in one side to adjust the height of the PCB, and check the position of the USB connector when bolting the PCB to keep it centered horizontally.

The USB connector touching the case is not a big deal at all. The outside housing is just connected to ground.

Bottom of the pcb should be insulated, usb connector may get some static charge through the metal case, but yeah, should not be a problem.

Had the same problem with my filco in the past, right after I changed to tex case

Put some non conductive padding between the case and the pcb, but most importantly the problem might be the connector on the pcb for the usb pass through. Try to re snug it and see how it goes

Mine does this every so often, even with a light jiggle on the case
