Okay, the beautiful assistant and I spent four hours fitting the new galvos today.
Points to note for anyone else looking at replacing ScanPro or DT scanners with the CT6800HPs:
1. The input pupil for the CT6800s is not in the same place as the ScanPros, and performance using the ScanPro 90-degree block sucks, so you will need to make an adaptor that will raise the CT6800 by about 6 mm and also move it forwards by about 4 mm.
2. The CT6800HP standard mirror set includes a Y-mirror which is very small in comparison to the ScanPro mirrors, so if you have a big fat flashlight beam coming from your 635nm red, you're going to lose a lot of it.
3. The CT documentation is a work of art. Very, very highly recommended.
4. The scanner feedback you'll need for your scan-fail interlock is on pin 1 of J4, not on the input connector like it is on the SCAN-D1 cards you get with the ScanPros. You don't need to hook up a ground to this connector, though you will need to connect together the grounds on the "DRIVE + RET" and "DRIVE - RET" for your common PSU layout. (It calls the power supply pins "DRIVE", and the signal pins "COMMAND".)
5. Performance just plain rocks.
6. This thread is worthless without pictures. This is the ILDA 12/30k test frame scanned at 40k and about 20 degrees.
