Hi Shahin, Barrel distortion is covering projector that project directly thru center of lens. Usually all projectors are made to project on certain angle, so frame is usually i position that lower side of frame is passing thru X axes and projecting image is straight line. Here we dont have any problem, but upper side of the frame is under huge distortion. Y sides usually can be adjusted by projector function. As I understood, your Barrel distortion function are equally make adjustment to both X sides, bottom and upper, and also two Y sides. Can you do something about that. I know that inside of projector is small square lens that can adjust projecting angle, but is limited to certain angle, and newer can project directly to center of lens, so I believe some more function to adjust that will make us possibility to reach perfect square frame. I hope that you understand what is my problem and that you can help us to solve this issue. Best regards Raca Sasa

Hi Shahin,

There is recently a new development board, the ASUS Tinkerboard, which runs Debian (but not Raspbian) and is comparable to the Raspberry Pi. Is NanoDLP compatabile with the Tinkerboard? (I would like to confirm that before I decide to purchase it).

HI To All, I was patient, but for my previous posts nobody responded or it seems that I have only this issue. I'm experiencing now serious problem, and I don't know where to look to fix it. Software was upgraded from 1330 to 1370, and after to 1373, with idea that new update will fix my problem, but same things appear again and again. I will give you my procedure of printing, in reason to be correct if I do something wrong. I dont claim to be so smart and know everything, especially since nobody jet has provide detail manual for this program, nider written form or video, except mUVe printer manual from with 1091 version of software old one year.
First I turn machine on, and Z axes after certain period of time start go up until reach Home limit, passe by for several millimeters and come back to home limit position.
At the same time when I start printer ON, I start DLP projector as well. ( warm up period ). First after I do after setting up Z axes, I go to Projector calibration, and send signal on FullHD Red Calib. When this appear I close shutter and go to Boundaries. Since I have several option for pixel size , I need to measure Square and adjust to certain dimension. When I achieve desired dimension and sharpness of printing eria , I go to Z axes calibration. I move Z axes until I reach desired level and then I start Red button Mesure Z axes. Machine goes up to the Home limit and I can proceed to printing. Since part is printed few times I will not explain how to upload file and slice them or upload already made PNG file sliced on external software, but file is ready for print , and shows first layer on preview. It appear number of layers. and starting layer. So I press Start from begining and with Z axes to go to printing position.
Now problem appear. DLP projector don't send first layer light , even it is shoved on prevue. Then I need to stop printing and wait until system finish moves and go to home limit position. (On all version I needed to do this procedure every time.) After that I will go again to Plates and I will start print from beginning and finally I will get picture appear on platform.
This issue happens all the time and it is not changed. I have work recently under 1330 and I have pass this as something that will be changed in the future in some future update. But new problem apear and this is something serious. Z axes will go up after press STOP button to certain level not more than 20mm and immediately start go down until reach bottom of VAT and start pushing until Current limit stops motor power supply. This has happen several times, I have made clean instal of software on separate SD cards and put in RPI , upgrade to Newest 1370 and same problem appear again and again. I dont know where to look and what to do. I believe that new Feature are important, but this is an serious issue on elementary level . I will upload my settings for machine if somebody can tell where I was wrong ider on settings or printing procedure.. Just to tell it is not color issue. I have check this already. Again I ask for complete detailed software manual. We are not all Wizards !  Thanks for reading.

Hi to all ! I need to know how can I defined end points to servo shutter. I know how to defined number of impulses, but shutter misposition - overshoot? Any suggestion how to control this, how to create endpoint of the servo motor?

I had perfect print few days ago with 25 micron Z resolution. But I wanted to try 10 micron resolution. I have create new profile, by making Clone from previews and start to change parameters for 10 microns resolution, by lowering exposition and speed up moves. I have Submit all in settings first make current default VAT and start creating new part to print . I have select new name and upload file for processing. Finally after Z and projector calibration, i have start print, but problem appear.   

Projector did not project anything, everything looks fine , Z axes moves nicely, I'm seeing layers on PC but they are not projected to surface. I have restart machine and PC , but same things occur again. Need advice how to solve this . I did something wrong , but I don't know what !

Any help?

Best regards

Hi to all,
