I've tried moving the tc, auto tune. didnt make any differance hardly at all moving the tc.@ 220 the oven will heat up to 250. tired by puting a part in the oven, mpt ranged from 290 to 385
I checked inside temp with another gauge, and it was right at what the pid control said. the only thing I can think is the need for a fan and/or vent. i feel like the oven tight, even at a 400 setting the wall never get warm and the mpt is around 480
oven temp ranges from 375 to 415. I do know the manual is helpful, but i have a hard time fully understanding.
