@beyond6strings @DirtyD @TeeJay1952 Thanks for helping with newbies! Brings back memories of broken switches. It was really only a few months ago when I was fielding endless broken switch issues. No more. The new switch was an LB life saver, and one of the most remarkable things about LB 3.0. Now that switch issue has been completely resolved, Lil' Bud just works. Sometimes you gotta slow down and smell the roses, as this is one goal I can mark off as complete. I have achieved Maytag repair man status. The improvements in performance are icing on the cake, and the cooling tube pure heaven for a taste chaser like me. @mr899 It's probably the switch if you're getting nothing. Unfortunately, I can't just pop in a new switch into an old LB, as so many other changes happen to allow the new switch. Do you know how old the unit is? When it comes to technique, everybody has different combinations that work for them. This is a manually regulated, on demand, powerful convection device, but the function of the device is only half of the formula. Herb prep, load, tamp, as well as tube set up, screen installation. Dry out the product before crumbling by hand or grinding. The basket screen should be clean, and with a proper set up, it'll stay pretty clean with just picking it clean. The basket screen should be set back so that it's about 1/16 to 1/8 from the tip. Only load your properly prepped herb to cover the screen. Tamp a bit so it stays in place and forms a flower puck, no air spaces, but not tight. Hit the button and draw slowly, get a sense of what the coil is doing, heat is doing. The idea is to get the heat to hover in the product at just the right time /temp, all controlled by your breath and trigger. @bossman Yes, a little *back* or *bottom* resistance helps the user regulate the heat. So does the glass insert, so does the hemp fiber, so does the distance. Without the used screen or henmp, it can be harder to get right, combustion more likely.
