How many here still have their Mark IV's and Mark X's either bought on a group buy here or purchased from Mike from Ballisticast?
I still have my Mark IV that I tweeked to run Magma molds. My minor PID control problem was fixed by adding a small fan to the control box. In addition I added a manual/automatic fan feature and programed the PID fan set points.
My pictures below.
