Well decided to upgrade my older AMP annealer with AZTEC. Paid the upgrade fee and go the code and followed the upgrade instructions. Big mistake and now it doesn't work in either mode. Matt with AMP has been very responsive but the problem is yet to be resolved. I love this annealer and sold my Bench Source because it worked so well. Hopefully I can get it resolved because not looking forward to laying out $1,600 for a new model. Been messing with it all day and had to walk out of the shop because I came near the point of launching it into orbit.
