Re:Version 1.4 Calculated Strip Length
Hello Wolfgang,

Thank you hanging with me while I get things sorted out.

I do realise that the the strip length is a calculated value, and it is not manually input by me. Since your message on Tuesday, I have been designating overlapping frames in the scanner settings,but I still get the results as it appears in the last image below.

I wonder now, if the Epson 4490 is somehow not up to the task, since you mentioned the INI settings are ported to the TWAIN setup when a scan is initiated. Have you had anybody use the 4490 successfully?

Thanks again for your patience,

Tom

Upper image in your last post looks OK
Hello Tom,

There is no problem with an Epson 4490. It should work as any other Epson scanner.
(EpsonScan is only slightly modified for the various scanner types according to the features
they can provide.)

To the images (screenshots) posted:
The upper image in your last post looks perfectly OK.
I have currently no idea, why the lower image shows the error. Probably you did not press the return button.
The provided values are saved to the INI file when returning to the main window of the CineStripScanner.
I will probably change that and do the save at the time the message "input OK" is presented.

I have uploaded Version 1.5 of CineStripScanner which now shows the calculated
length. I hope it is now as you expect it to be.

Wolfgang

Success
Hello Wolfgang,

I think I solved the narrow script scanning problem. I was measuring from the full scanner edge for the "from scanner window right" parameter. Since the 4490 has a narrow TPU, I measured from the edge of that, which is effectively "0mm", but I put in "1mm" to account for my custom scan plate,and am now able to scan the full strip. Hooray! It is however difficult to make these parameters "stick" and I occasionally get an Exception error. Also, the "frames overlapping" parameter is hard to change from it's default setting of 0 without crashing for some reason, but I am able to eventually get everything input correctly.

Moving on though, the stepper motor no longer responds. I have tested the Uno board, motor shield, and motor with sketch scripts and they all work fine, but will not respond within CSS.
But, before you go digging into that, I will be getting a windows 7 laptop soon that will be solely dedicated to the scanning system and will start clean with testing.

One more question. Is CSS using still using the Arduino .ino sketches, or is it embedded in the code now? I don't see an Arduino scripts folder in the Program Files.

cheers,
Tom

Hello Tom,

could you please be a little more detailed about the problem in setting the overlap parameter.
(A possible bypass: you can adjust the parameters in the INI file. It is possible to edit it with a text editor - eg. NotePad++ )

If you use the Arduino board, you still have to use the Arduino INO script ( no change against the ScanController). And you must install the specific FTDI USB drivers. You must also make sure, that you supply the board with sufficient power. What is coming from the USB port is not enough. You need a seperate power supply (e.g. from an old external disk drive) to run the stepper motor.

Hi Wolfgang,

My new laptop will be arriving in a few days, and I will be able to start with a clean system, just to make sure I didn't add anything to mess up the transport system. If the problem persists, I'll send you a short video showing the trouble I'm have with parameter inputs. I'm reasonably confident that it won't be a problem though. As you mentioned, I can easily edit the INI file with Notepad ++, so that's a good option.

I have external power going to the UNO board, but come to think of it, I'm not sure I loaded the proper FTDI Drivers moving forward. I will check that out as well. I think I can get this all sorted in the next few days.

Thank you for all your help!

Tom
