Welcome!
Indeed, as you discovered, most "pen" size vapes cannot vape raw flowers, despite the marketing claims, most simply combust the herbs.
You have the Pax2, that's a great start. I suggest you head over to the Pax2 thread for suggestions on how to achieve optimal performance from the vape (to ensure you're using it correctly).
In regards to your journey with 'bud', I really don't know what to tell you..... every person is different. Cannabis is an amazing plant with many medicinal properties. Some people benefit from low temp vaping, while others prefer/need higher temperatures for sedative and pain relief.
What you need to do is experiment, practice medicating to see where things go. You may find the higher temperatures are unnecessary (undesired?). It is a delayed reaction - wait 10 minutes after vaping to see how you feel before reloading.
I seem to get small clouds, but do not feel the effect of the bud.
If you were combusting occasionally before vaporizing, you may not feel "medicated" for the first few sessions. The key to fucking combustion is to dedicate yourself to vaporizing exclusively for several weeks.
