I am the proud owner of an Auber RDK-300 and have experience with the RDK-200. IME the units perform differently with different nails and coil pairings. Im curious to see which temperatures people are running on what setups and maybe glean some knowledge to get that temp dial perfect. Hardware: Auber RDK 300, Dnail 16mm coil, HE OG Enail w/sapphire insert Temps: small dabs 720, big dabs 730 And now a question: When I first got my unit it would heat up quickly, stop for a while then creep up VERY slowly. I emailed auber and they promptly and politely told me that the problem is due to the combination of high heat loss of the nail design, lower power coil, and high setting temperature. They said I should reduce the P to 100 and increase IEg to 60 which solved the problem! However with Quartz halo coming in the mail any day will I need to adjust my PID again for a flat Dnail coil?
