I built a Ploopy mouse yesterday. All the buttons work, and for the most part it’s fine. But the movement is on and off laggy. Sometimes it works great, even faster than what I had before, and then it just stalls or stutters and slows down for a several seconds. I’ve tried a couple different USB cables, I’ve taken it apart and tried to reseat everything, I took the optic piece off and tried to blow out any dust that may have been in there. But it’s still on and off laggy. Happens in windows and Linux both.

This is only the second thing I’ve ever soldered, and I’m sure I did a pretty trash job of it. The board is mostly done but you have to solder the optical chip in at build time. Could that cause it to be laggy like that? I don’t see any pins accidentally soldered together, there’s separation between each soldered lead, though I definitely can’t do the nice pretty little dots, they’re ugly as hell.

They’ve provided instructions to build/update the firmware, could that help maybe?

Just wondering if there’s any other ideas to help fix this? If I knew it was a legit bad board or something I could maybe go back to the seller and see about getting a replacement, but I’m afraid my soldering could be at fault in which case I don’t want to make that his problem. So I’m hoping someone here may have an idea. I love the idea of this diy 3d printed mouse, just hoping it wasn’t a $100 mistake.

Thanks in advance.
