What do u mean its not doing it.. Excuse my ignorance.

Ill give yah my setup..

Flexwatt routered into rack.. Herpstat probe in a routered groove under the flexwatt so sandwhiched between flet watt and malamine.. Tubs with slight raised bottom above.. Herpatat probe reads 107ish and infrared temp gun says plastic tub is 91ish. So a lil substrate on top gives me 88-90.


Im not following why you would move ur probe?
