It's been a few years since i worked on a CP machine but your st17 & 19 errors are probably down to grease in the clutches at the top of the shafts, if too much grease is put onto the turret gear during maintenance it tends to spray into these clutch

James, If you have a true MSD issue, then baking them AFTER your reflow is not going to fix the issue. I would have to agree with GS and look at trapped cleaner media (if your not No-clean) under the components, or inside connectors. If your runnin
