I moved the fixed rail in by about 2 inches and it seems to have done the trick. Rail movement is easy, moving machine to keep all conveyors in line not so easy

If it's forced air convection I'd check all the circulating fans and filters. Also if its a clam shell bonnet make sure it's closed all the way and the seal is good. You didn't specify whether it is one zone or the full length of the oven, I do not w

We are running a Heller 1707 EXL reflow oven, but we have a temperature variation across the board. When the oven first comes up to temperature, the centre of the board is 10degC hotter than the inside rail which is a further 10degC hotter than the

Generally the heller exl range has issues in cross profile, some machines more than others. I have see as bad as 15 deg c and as low as 5 deg c ranging from entire length to a few zones. They never match the specification in reality. The markiii is
