GMK causes scratchy sound?
« on: Wed, 20 September 2023, 11:40:38 »
I've got this strange problem with my Keychron Q3 where GMK and DCX Keycaps (they're almost identical) cause a strange scratchy feeling and sound.
It's very subtle, as if the switches are scratchy, but they alone cant be the problem:
Other keycaps are fine. Also the exact same GMK keycaps sound fine in other keyboards (e.g. ZoomTKL).

This happens only with my Q3, changing the switches does not help either. There is no interference with the switches.

It's really annoying and I've got no clue what this is caused by... maybe the keycaps resonate somehow with the switches or case?

Did anyone else experience this? It drives me crazy that I cant figure out why  :p

are the stems on the keycaps defective? the 2 gmk kits ive had both had stems that were off-center and hit the switch
someone needs to make an aussie keyboard community called QMƎɹ┴⅄. get it? haha :D

I second this, one of the gmk sets I've had had off center stems

To put a different idea out there, maybe the switch housing is interfering with cherry profile keycaps, causing that subtle scratch. Not sure about that though, if you have different types of switches than the ones in the Q3 then maybe replace a few to see if they have this issue as well.

cherry blacks - unlubed - filmed and springswapped with tx 55g mediums - alu Plate | pretty happy with this, the blacks were cherry picked so they weren't that scratchy to begin with, but currently breaking them in, may lube them with a dry lube like ro59 or ptfe powder.
| hhkb bt
lubed with tribosys 3203 | like topre a lot, prefer it lubed but did make less tactile but that might have been a skill issue. probably will get more tactile over time as the domes age.

bad orange alps lol | definitely needs a restoration. planning on wax boiling them and maybe a replacement pcb because the board has only 2 key rollover apparently.
| praxis
gateron yellows - lubed with 205g0 - 62g tx mediums - pc plate | probably my favourite keyboard already, feels super nice and sounds pretty good, it's got a great layout as well. probably gonna build this with mx browns, I feel like it would suit the board more.
| camo filco
stock with silent reds | Pretty cool looking board, the silent reds are actually good, they are smooth and I don't mind the mushiness (it's not even that mushy as well). the layout is pretty weird, but is useable. will probably mod this in the future. maybe a pcb and plate swap, change the keycaps to something dolch like, and also spring swap the springs in the silent reds.

May be it is because of the north-facing PCB? I don't remember if Keychron PCB is north or south-facing. But north-facing does create a scratchy sound and weird noise with my GMK Laser.
