nanoDLP

Hello,

I will try to describe here how to configure nanoDLP for the LCD SLA 3d printer 'Proniks KLD-LCD1260' (aka YHD-101) that you can find on Alibaba/eBay for a few hundred USD (http://grauonline.de/wordpress/?page_id=1767).

1) LCD SLA printer specs:
    photo mask: LCD 5.5 inch screen, 1440 x 2560  (537 PPI)
    Light: UV-LED 405 nm
    Print size: 121*68*150mm(XYZ)
    Resolution :   25 micron
    Print layer : 0.035mm-0.1mm
    Print Speed: 15mm-35 mm/Hour
    Resin: LCD/SLA printer resin
    signal input: HDMI
    PCB1:  Arduino Mega 2560 (Sprinter firmware) + stepper motor driver
    PCB2: LCD controller (HDMI interface)

2) configure Raspberry PI3 HDMI to support 1440x2560 pixel resolution:
sudo nano /boot/config.txt:

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

3) printer GCodes:
G28 home axis
G1 X0 Y0 Z100 F300 move to position (0,0,100)
M106 switch UV-LED on
M107 switch UV-LED off
