Hello, I just built my first custom keyboard. The spacebar and backspace are sticking when I press them down. I put foam in the keyboard to dampen the sound and I also did the tape mod where you put tape on the back of the PCB. I used Glorious Panda switches and the TM680 case. I looked it up and found that the stabs could be lubed too much but I doubt it (I didn't lube them) I think they come factory lubed. Any help would be much appreciated.
