I have only hot barred with reflowed solder and no clean flux. And it works well for us. Can you try tinning some of the Leads ahead of hotbarring? Or maybe try cleaning some with flux.

When was the last time you changed the flat ribbon cable on the top? Anytime I had trouble with a mydata that was the first thing they asked.

The leads on the FPC are pre-tinned on both sides with SAC305. The receiving leads are AU. We do not experience any wetting issues that would suggest oxidation.

Interesting. I will replace that cable and see what happens. I suppose there is a lot of movement it has to endure.

Any Suggestions on How to remove oxidation on connector pins. The boards have been sitting for awhile and can't be washed due to transformers and open relays that are on the board.

I just received replacement XWB3 and 3PT1 boards. I swapped them out and it seems to have fixed that issue. Thank you all for the help!

The camera crashing is usually a fault with the encoder on the Y motor assembly. someething to do with not finding a home pulse I think. Anyway, replace the motor/encoder and recalibrate and you should be good to go

Can you brush some flux on the connector pins and run them through a heat cycle, hot enough to activate the flux, but not enough for solder to melt or component damage? That should remove most of the oxidation. Then, you can run it through your regul
