I ran a few static tests yesterday on ETMY HEPI. Things like linearity & range of motion etc. Attached is a two plot of trends on the HEPI Cartesian basis IPS. X & Y have moved a few ums while Z and Rx & Ry are pretty steady. Rz has rotated a little more now out to 22urads. Again this is good for the alignment now as long as it doesn't go further.
