Just to remind you that there is lots of stuff built into the program to do the testing you need to do when you start up again.
From the opening menu:
2)Test 10)RdLim 2)MovLim
Gets you to a menu where you can move each thing to its limit. Note that when you do this, there is a line displayed with 4 hex characters which display the bits (by ascii code - 4 switches per character) as the device moves.
From the opening menu:
2)Test 6)TstMot 5)Specfy
Asks for you to specify a motor.
0 V Focus Motor 1 Dec Drive Motor 2 Dec Clamp Motor 3 I Focus Motor
You can then specify the number of steps. A few steps are enough to feel if you have a second person with a finger on the motor shaft. The screw motors move 0.001" per step. You are also asked to specify a direction. 1 is away from the limit switch, 2 is toward it.
From the opening menu:
2)Test 8) TstRA
Gets a menu where you can test the RA drive. I would start with 1)RAOn which should move the right direction for tracking the sky. Since it does not move very fast, there is time to check it before it jams into the limit switch. Once you have it going in the right direction, then you can use the move to limit menu to check that the limit switch is working.
From the opening menu:
2)Test 6)TstMot 1)V Focs
Gets you a menu where 1)Exrciz will cause the motor to continuously move in and out. This is good if there is only one of you and you want to test if something is working.
The other motors are similar, except if you move the RA drive motor you may have to take the clamp off first. Check the code, I may unclamp before I start the Exercize.
From the opening menu:
2)Test 5)MaServ
Gets you to a menu where you can test the MA Servos that drive the shutters. 1)TstMA0 for example, opens and closes the V shutter at a few second interval.
I would run through all the above, making sure all the motors move, the shutters operae, and all the limit switches work.
