This is a non-standard cable. Mario checked continuity and it looks fine. He noticed a`some bent pins and loose wires and reconnected. Over to Uli for testing.

Message-ID: Mary purchased a new unit. With Eric's help I replaced the old unit (stage/laser head, motor controller) and confirmed operation. A couple of comments: 1. The laser power (coming from the Coral box?) connector is a slightly different type and I had to remove the locking ears to get it to try to go in to the socket. Even so it doesn't go in smoothly. We may want to replace with a different (correct) connector. 2. Mary had hoped that the system would now have two laser frequencies (as the software indicates). However, it only seems to have the 750 nm, not the 810 nm we were using (or viceversa, I get confused). 3. We have temporarily moved the pc on the table since the 64 pin cable is short. We will try to get an extender. System in yellow until Uli completely checks it out.

BUT, what I notice is that the indicator bar is not correct in where it thinks the stage is relative to where the stage ACTUALLY is. So you have to fool it. I don't know how to teach it the correct position.

There is apparently a administrator mode which allows the zero point to be set, however the password Jim McVittie supplied didn't work. I replaced the display and keyboard. Better than nothing.

All other position constants were the same, so I edited the file to that number. I was then able to get the system to go to "home" (all the way in) and "park" (all the way out). With EricP's help I was able to make a measurement of the standard, which came out to the correct number. Unfortunately, however, the stage would occasionally go crazy and lose the correct location. If I put it back to the right position (usually by turning off the stage and moving the counters), the home and park will work reliably. Unfortunately I am not confident that it won't get lost, so I don't think we should release it at this time. I will continue to try swaping out components. It may be the computer controller card, and we don't have one of those and they are no longer made.

I changed the park position to -70 mm to try to keep the system from running to the end of the lead screw. Unfortunately, it still occasionally loses count going back to the home position and will even run through the limit switch. Mary found the password "FSM" but that does not allow the reset of the zero on the motor control page. If we do not try to go to home it may be runnable. Uli should check it out.
