rebuilding DLP 3D printer from source

Other Parts Discussed in Thread: DLP4500, DLPC350

Hello,

I intend to use DLP4500 for 3d printing application. I want to modify the source code for 3D printer but I am a newbie in C++ programming and I have no experience with QT, OpenCV and Visual Studio at all.

I'd appreciate any help with the following-

1) After editing the source and rebuilding it on QT, should I expect the GUI to run (reflecting the changes in the source)? If not, then how do I upload the images to the flash memory on Lightcrafter 4500 board? Please walk me through the steps to run the new source (or exe) and upload images 

2) On-board Flash memory is not sufficient for my application since the number of images would be extremely large. What is a possible way when I can store first 48 images (24 bit bmp), erase them once projected on the DLP, store the next 48 images,  and so on? Can you suggest a method to display a large number of images for Flash memory to be an input source?

3) As specified in the document on the modifications in DLP4500 for 3d printer, the blue LED can be replaced with a UV LED. But I want to use an external UV source to project on the DLP, and dont want to use the light engine on DLP4500 at all. What modifications should be needed (in source code as well as on DLP4500 EVM)

Thanks a lot for your help.

    Hi Pracheetee,

    1) Yes, you should be able to run the GUI out of At after you successfully build it. You use the 'Run' command. You can also run the executable generated in the build folder. The GUI is what loads the slices onto the LCr4500. Please see the instructions in the user's guide for further details.

    2) You will need to modify the source code in such a way that after the LCr4500 completes projecting the last layer loaded into the device, it is reloaded with the additional images from the PC/GUI. This would repeatedly load the next set of images into the flash.

    3) The LightCrafter4500 is designed so that alternative light engines can be experimented with, however we do not support this type of activity. Please see our documentation of the LightCrafter4500 and well as the DLP4500 and DLPC350 devices to get an understanding of making this type of change. We also have 3rd party partners who create UV platforms based on the DLP4500 chipset. Please take a look at the page below for more information on their offerings.
