Would any other touch sensors be viable to work with on a home project for example resistive, or is that likely to put oo much strain on the LCD?

There are two places where the batch controller looks for the names of dialogs and controls which in English are labeled “Open”. You can specify alternative names via the command-line. For example:

stitch.exe -dialogName “Öffnen” -openName “Öffnen” …

For more info, check this comment which describes how to make it work in French:

Hope this helps.

I run a German version of Windows. My “Open” Button is named “Öffnen”. That might be the reasion why it does not work:

Control : Cannot find dialog “Open”

Could you please send me a version works for German? I do not have a C compiler and I do not know C programming…

By the way: “Close” is “Schliessen”

Thanks

I asked the suppliers to polish the edges after cutting. I’m not sure what method they used. The surface looked pretty smooth, though it was not completely “flat”, probably cut with being cut with a bandsaw. If it is laser-cut then you’d probably get a better finish.

A flat, highly polished surface is more important for FTIR designs, where you need as much internal reflection as possible. If you are using a DSI design (with Endlighten), its probably not that critical.

Are you sure you’ve got enough power to your LEDs? If you’re using the flex ribbon you’ll need at least a 2A at 12V. Check the data sheet for the power consumption per meter.

You site is a big help and thanks for answering our questions.

Did you polish the edges of the acrylic? If so, what method did you use?

I polished mine with 320 - 400 grit sand paper and then a buffing wheel on a drill.
It doesn’t have the same finish you would expect from something like flame polishing and I am afraid that it the way I will have to go.
I am just not getting the IR lights into the acrylic good enough.

Thanks again,

Here’s the part description from the invoice:

1 x Narrow Dimmable LED Ribbon Flex by the 5-meter reel
(InfraRed 850 nm) (irrf850-reel)

At the time, the cost was $177 plus freight.

The size of the acrylic depends on how you’re going to mount it. I ended up mounting the acrylic as the top surface of my box, so it rested on top of the four sides. I made it big enough for a 25mm border on all sides. Initially I was going to sandwich the panel between the endlighten and a separate smaller sheet of perspex, but in the end I supported the panel on a small ledge inside the box. An advantage of the “sandwich” idea is that the whole assembley is more-or-less self supporting, but if you include the driver board in the sandwich its quite a bit larger on the top side. Make sure you support the weight of the acrylic - don’t just rest it on top of the LCD or you’ll end up distorting or cracking it.

Hope this helps.

Thanks again,
John
