I am working with a CM in Taiwan and we are seeing significant differences between the paste printing bon the forward stroke vs the backward stroke. Print parameters are the same (pressure, speed, snap off speed) but there is a significant difference in the measurements from the SPI system. Any thoughts?

My first move is inspect the blades, swap the blades around and re-balance the blades to see if it is a problem that corresponds with a specific blade. Also try a different pair of blades. Full restart on the printer incase of an odd software problem. Make sure the board is secure while clamped in the print position.
