At only .01 - .02 rise in resistance from a cold coil to hot, it would seem that you are not getting enough of a rise in resistance. If the board doesn't see enough rise in resistance in the first second or so, it will drop out of TC. For instance, my current SS316L coil is .178 cold & rises to .210 - .211 after firing. Have you tried spacing your coils? What kind of atty? Can you post a screen shot of Device Monitor while firing, with the following fields checked...Power, Power Set, Temperature, Temperature Set, Cold Ohms & Live Ohms...
