Hi everyone,
I am happy user of Nano DLP installed on my machine . But if have one problem and can t find solution.
My machine use raspberry pi3 with MK board. I have replace pointerface with muve3D firmeware And Photonic3D with NanoDLP build 1357.
Everything working fine when I import PNG slices from CW. Good prints.
But when I use the nanodlp slicer the parts are mirrored, x reduced 30% and y reduced 50%. Z ok.
I try to play with projector parameters, raspy config.txt. But no success.
Anyone have idea?
another bug is if I use the projector adjustment patterns they are rotated 90 deg.
Thanks for your help.

To mirror image edit config.txt file.
90 degrees
display_rotate=1
180 degrees
display_rotate=2
270 degrees
display_rotate=3
horizontal flip
display_rotate=0x10000
vertical flip
display_rotate=0x20000
If you have x,y issue. There are 4 options effect size of the rendered image. The projector resolution and x/y resolution on setup page. Override X/Y Resolution and modify x/y resolution on profile page.

Hi Shahin
Thanks for your fast answer.
For the X,Y size, i have found a Override X/Y Resolution at 65 on profile and it may be this the problem for my size. I will try soon to see if fixed.
For the Config.txt i do not have any display_rotate (in raspi). but i have this setting under
hdmi_force_hotplug=1
#hdmi_ignore_edid=0xa5000080
disable_overscan=1
framebuffer_depth=24
gpu_mem=192
framebuffer_ignore_alpha=1
#start_x=1
hdmi_cvt=1440 2560 48
hdmi_group=2
hdmi_mode=87
hdmi_pixel_freq_limit=400000000
hvs_priority=0x32ff
max_framebuffer_width=1440
max_framebuffer_height=2560
framebuffer_width=1440
framebuffer_height=2560
config_hdmi_boost=4
#hdmi_timings=1440 0 16 16 64 2560 0 5 2 1 0 0 0 50 0 176947200 3
#hdmi_cvt 2560 1440 50
when i print with import PNG files, the display is correct on the machine screen, the width and height are in full screen with good size. Print is correct in size.
When i go in Projector calibration / full HD calibration the grid is rotated 90 deg.
When i use Nanodlp slicing, the display is ok in width and height full screen, only mirrored in X.
That's what i do not understand.

Try add options listed above, it probably fix the issue.

Hi Shahin
The flip is corrected adding the line "display_rotate=0x10000 " . Now everything working fine.
Still have projector calibration who HD pages still have 90 deg rotation clockwise displayed on the LCD.
Thanks.

Thank you for the update. I do not get why HD pages are still have 90 deg rotation.
