Wanhao D7 Image is rotated

I followed the D7 wiki and I have NanoDLP setup on an RPi 3 and it seems like mostly everything is working correctly. The buttons in the Z calibration are doing some strange things but first I would like to get the image rotated properly. I thought having displayimage =0x10000 in the config.txt would have the image oriented properly on the D7 but it is not. The NanoDLP Plates Printing screen shows a horizontal image of the layer but I am seeing it turned 90 on the D7 window.

What am I missing here in my Config.txt to get the screen rotated properly?

# Wanhao D7 nanodlp config
# V1.0 3-feb-2017

# CAMERA SETTINGS ( 1 = ON, 0 = OFF)
#start_x=1
disable_camera_led=1
# uncomment this if your display has a black border of unused pixels visible
# and your display can output without overscan
disable_overscan=1

# uncomment the following to adjust overscan. Use positive numbers if console
# goes off screen, and negative if there is too much border
#overscan_left=16
#overscan_right=16
#overscan_top=16
#overscan_bottom=16

Re: Wanhao D7 Image is rotated

Its been a while since i played with my Raspi screen settings but heres my section of config

# DISPLAY SETTINGS
gpu_mem=128
hdmi_force_hotplug=1
hdmi_timings=1440 0 50 10 35 2560 0 4 2 2 0 0 0 50 0 198000000 0
hdmi_group=2
hdmi_mode=87
hdmi_pixel_freq_limit=500000000
hvs_priority=0x32ff
max_framebuffer_width=1440
max_framebuffer_height=2560
framebuffer_width=1440
framebuffer_height=2560
framebuffer_depth=24
framebuffer_ignore_alpha=1
config_hdmi_boost=2
dtparam=i2c_arm=on
display_rotate=0

If i remember correctly the "display_rotate = " can be set to 0,1,2 or 3  Each one rotating respectively 90 degrees
It might be worth trying on you machine.
Good luck

Re: Wanhao D7 Image is rotated

I would confirm that given config doesn't work with the last version of NanoDLP.
I've got installed older nanodlp_d7_0517.zip mentioned here

3dprinterwiki (dot) info (slash) wiki/wanhao-duplicator-d7-sla/d7-nanodlp-settings-2/easy-nanodlp-install-option/
3dprinterwiki (dot) info (slash) wiki/wanhao-duplicator-d7-sla/d7-nanodlp-settings-2/
(sorry, looks like new users can't post links normally*)

and everything start functioning like a charm.

Also, I would report one more issue. The /repo/ directory has been disappeared from the official site as well. So all printers and machine profiles currently are inaccessible (nor directly neither form the FW setup). So probably the best way is to use previous (e.g. that version that I mentioned above). There are all profiles included in the image (+ direct links are provided, if required).

Please note that the mentioned version has an (at leas I that I know) issue with z-axis top fixation (viewtopic.php?id=1216, viewtopic.php?id=427). But in general it is not a problem while you don't move head too high manually

Re: Wanhao D7 Image is rotated

Configs are exists on nanodlp images. /repo/ does not get enough attention to keep it updated.
