We are seeing two issues with the autocal of the 18bit DAC cards (used almost exclusively by suspension models). The first is a failure of the autocal; the second is the autocal succeeding but taking longer than normal.
There are three calibration completion times: ~5.1S for unmodified DAC, ~5.3S for modified DAC, ~6.5S for modified long-running DAC
h1sus2b, h1sush34, h1susex, h1susey all have no DAC issues
h1sush2a: the third DAC is taking 6.5S to complete. This DAC is shared between PRM and PR3 models. First two channels are PRM M1 Right and Side. Last six channels are PR3 M1 T1,T2,T3,Left,Right,Side.
h1sush56: this has unmodified cards. 4th DAC is failing autocal
h1susb123: This one is strange:
On first autocal run after a computer reboot: 7th DAC failed autocal
On first restart of all models: 1st DAC failed autocal, 7th DAC succeeded
On second restart of all models: 1st DAC failed autocal, all others good (consistent restart behavior)
In all cases, 5th DAC card is running long for autocal (6.57S).
In the current situation with the 7th card now succeeding and the 1st DAC failing, the 1st DAC is driving ITMY M0 (F1,F2,F3,LF,RT,SD) and M0 (LF,RT)
