I recently bought a Peak Pro with the 3dxl chamber from a friend of mine, and I almost immediately started running into issues with it. When I first got it I took it home, loaded up a dab with some fancy rosin I bought, and it didn’t seem to work on the first hit so I tried another and it seemed to work fine. Since then I haven’t been able to get it to work:

When I load up a dab, everything seems to work smoothly until the inhale itself - it produces some vapor on the beginning of the first rip, but even seems to die out and stop/struggle to create vapor (or deliver it to the glass) during the same first rip. After that it’ll seem to barely hit and will quickly descend into not hitting at all. 

I’ve cleaned the entire device and deep cleaned the chamber multiple times, but there’s still a good amount of stubborn chazz that won’t come out. I’ve fiddled with the heat and vapor settings but nothing has seemed to make a difference, and I’ve done as much surface level research/troubleshooting I could over the past couple days but to no avail. 

Does anyone have any solutions or tips to get it working? 
Or any way to tell what the actual problem is and whether I’m cooked (issue with the device itself) or semi cooked (need to replace chamber or glass)? 

*also - chamber photo was taken after a dab before cleaning for reference if it helps at all. After cleaning wax isn’t stuck to the bottom like that, just a streak of dark impenetrable chazz on the side
