Hello dtic

I's working now. Turns out when I launch the EXE file it still saves to PC by default, but if I launch the modified AHK file it shoots direct to camera. Really appreciate it for making this software as well as helping my with the RAW function. Thank you so much. : )

Good to hear! To have the modifications in the .exe you need to compile the modified .ahk. If you did a standard install of Autohotkey you can right click the .ahk and choose compile. But the functionality is the same so you might as well keep using the the modified .ahk

I now got around to test TwoCamControl in Windows 10, and I get a similar error as rcull reported when I run TwoCamControl.exe on a Win 10 computer with a non-english language/keyboard setting.

The single quote character ' and some others are replaced by other characters when TwoCamControl sends to the chdkptp interactive CLI inside the cmd window. But there is no such error when using the uncompiled TwoCamControl.ahk . I can send single quote characters from compiled autohotkey scripts to cmd windows, the error occurs only when sending to the chdkptp interactive CLI .

I haven't yet pinned down the cause of the problem or found a solution (Some setting in autohotkey source? Autohotkey compiler? chdkptp? cmd?).
It could help me troubleshooting if someone else with Windows 10 checks and reports back here if they get the same error with TwoCamControl version 151121 from here http://www.diybookscanner.org/forum/vie ... =20#p19588

REQUIREMENTS
- Two Canon cameras with CHDK installed ( http://chdk.wikia.com/wiki/CHDK_in_Brief )

- Preview button for use when setting up a project (*not* live preview while shooting). After zoom and focus lock press preview to see two images in your default image viewer. If they are blurry unlock and relock focus and retry.
- Options for zoom steps, parameters for chdkptp, and mouse and keyboard controls.

USEFUL TIP
Use a wireless mouse for automatic triggering when you lower the platen. Make a plastic/tape "finger" that protrudes a little from the platen side. Tape a wireless mouse in place so that the finger touches and scrolls the mouse wheel down every time the platen is lowered.

New beta version of TwoCamControl

c46c5c13521ac11d3b387b534a7bad6d *TwoCamControl160810.zip

CHANGELOG
160810
- right click Preview: option to show same preview again
- right click Project: option to cancel current project but keep cameras on
- option to only save to camera (not download to pc)
- fix non-english systems sent wrong characters to rsint cmd window, the fix sends ansi codes instead
- close/cancel uses quicker rsint q (quit) command

Feedback wanted on the fix for wrong characters in the rsint cmd window in Win 10 on non-english systems (see this post for context). Are some characters in the cmd window still wrong? If so, try using folder paths with only english a-z letters. If that doesn't fix it then post here and say which characters are still wrong.

If you found your camera in there Im pretty sure the program will work for you. and as far as i know you will also be able to use both cameras at the "same time".....once everything is set up that is. im trying to set this up myself and im a little lost...trying to get my question strait before i ask it.



i wonder how often this forum is monitored.....

hahaha what is a walk in the park for some here feels like deep space 9 to me....

Yes, but there are no smart features to help you go two rounds, first all right pages then all left. There will be some error text in one cmd window about not finding the second camera, but the images from the first camera will be saved without any issue.

Fast. For maximum speed from button press to finished shot go to Setup tab and set "Wait" to "0" and under "rsint options" remove "-cmdwait=600".

But for maximum speed workflow keep the default wait/rsint settings and use a wireless mouse for automatic triggering when you lower the platen. Make a plastic/tape "finger" that protrudes a little from the platen side. Tape a wireless mouse in place so that the finger touches and scrolls the mouse wheel down every time the platen is lowered. Then tweak the delay time settings to match the time it takes to pressed the platen down.

i mean how fast do u think will it be the process to capture an image and download from a camera a3300 to a folder in a pc with windows and then with a script in python like SpreadPi but with scantaylor and abbyy.
