We are looking at buying a new (or used) oven for low-mid volume Pb-free production. I have looked at the smaller Hellers, BTU, vitronics, etc. and I am also looking at the Manncorp CR-6000. I want at elast 5 zones, top and bottom, air (no N2) pi

Common problem. Start at the Encoder and measure the 5v square wave. Trace it back to the Frequency to Analogue converter, then to the controler. I assume that your conveyor is in good shape. i.e. With the motor disconnected, the chain should flow f

Evan, not sure if you solved it already. I wanted to mention any couplings being lose related to the motor and conveyor movement. Some have set screws that get lose with time. Also when you say manually, do you meant with a handle or you mean through
