In perspective, Nanodlp have some kindly tools which "open" some degrees of freedom(i2C,serial,formulas), i hope someday nano becomes a great product.

"In simple terms, you could think of the horizontal dimension of each pixel as being stretched to 2x it's size. When projected, the 912 x 1140 pixels become 1824 x 1140, which is 16:10 aspect ratio. The trick here though is to understand that this is just a model of what's happening, you don't really have 1824 pixels on the horizontal axis."

found a solution,

it was the Y Resoluion setting inside setup, it should match the lateral distortion due by pattern mode theres no resampling

but before you must set the the config.txt inside boot section to match frequencies and DMT custom setings

you should set:

hdmi_cvt=912 1140 60 5 0 0 0 this will set video composite freq and aspect ratio to match the dmd controler dependencies.
hdmi_mode=87
hdmi_group=2

hdmi_pixel_encoding=2 RGB full      ( 0-255) this will force rgb encoding

#hdmi_ignore_edid Enables the ignoring of EDID/display data
hdmi_ignore_edid=0xa5000080

hdmi_ignore_edid_audio=1
hdmi_drive=2
sdtv_disable_colourburst=1 disables colour burst on composite output

#9 Re: Help and Support » issue with lightcrafter4500 module and image output » 2017-09-24 18:09:39

the config.txt inside /printer may influence the config.txt inside /boot?

#10 Re: Help and Support » issue with lightcrafter4500 module and image output » 2017-09-24 18:07:27

config.txt inside /printer

disable_overscan=1

hdmi_force_hotplug=1

hdmi_group=2
hdmi_mode=87
hdmi_cvt=912 1140 59.91 5 0 0 0

hdmi_drive=2

config_hdmi_boost=4
hdmi_pixel_encoding=2

framebuffer_depth=8
framebuffer_ignore_alpha=1

Hi everybody,

This issue is a bit drifted from forum aim here,
maybe this problem is not related with nanodlp, my first doubt is related with slicer internal workarounds if it capable to deal with non-standard resolution.


On nanodlp setup,  enter correct native resolution(lightcrafter) which is 912x1140 to work with pattern mode to get real pixel relay without any processing.

and from raspberry side i modify the config.txt to output this native resolution with custom mode dvi group:


pi@raspberrypi:~ $ tvservice -s
state 0x120006 [DVI DMT (87) RGB full 16:10], 912x1140 @ 60.00Hz, progressive


everything matched, when you open preview on nanodlp you could see the aspect ratio is correct on layer preview page, even on projector gui control software.
but the output is out incorrect sized.

anyone would make a guess?

Does it display any error?

after nano injection, i cant ssh, it "seems" dhcp or network did not enable by default,
cant be visible to router even on cable connection even with static network config.
it stay on terminal screem, did not appear the projection canvas/screen.

them i cloned the old sdcard image after feels nanodlp did not been activate and not boot as normal before...

Hi folks,

anybody experience any issues? yesterday i have been building a brand new setup, and nano not seems to be build as normal.... maybe should be any fault of mine, just to wonder if i could retry or i need to kkeeep the old jessie on fire

thanx

maybe there is more surround wifi signals interfering on your spot, i placed a usb wifi dongle on rpi3 and solved the problem

#16 Re: Help and Support » nanoDLP and LightCrafter4500 » 2017-07-25 16:24:53

Its kind strange, i think the output video should be configured to DSI display port.

the lc4500 is working with other hardware? did you test Internal test pattern? verify the flat cable in LC4500, did you modify the unity ? change to uv led or you buy already with uv option? its normal some "leakage" when mirror are off-state. so theres no input signal comming...

I consider you install a fresh image on rasp and only change the resolution to 1280x800 inside config.txt everything else should run out-of-the-box.

i will post today later my rasp config.txt so you could copy/paste/try

#18 Re: Feature Requests » Grey exposure control » 2017-07-07 12:28:20

Yes.

But  i thought if it could be "Dynamiically formulated" in dimming pixel defined by area section.

as exemple.

we have a small pillar([[SmallestArea]]  which we would want no pixel dimming and a [[LargestArea]] which we want pixel dimming, so we could define th ammount of grey control defined by area.

Hi fellows,

I just wondering to control the grey exposure based by area calculation, just wondering to handle formulas to define it, i think it could be implemented as a formula box to dimming control parameter?

nano [[IsBurninLayers]]?
yes it is.

{ ([[IsBurninLayer]])*3.5 + ([[IsBurninLayer]]==0) * (1 / ( 0.7 + ( 2.718**-(0.02*https://youtu.be/0fYL_qiDYf0 - 3))) +1.7 ) }

#21 Re: Help and Support » How to read the Calibration Plate? » 2017-07-03 06:37:59

do you use lamp or led on your system?

Temp will affect viscosity, which by the way influence somehow in kinects change, if you do some search about temp, you will see at normal conditions that temperature will not have significant change on resin kinects, if should take account primary the energy dose and dynamics.

#22 Re: Tips, Tricks and Tutorials » A visual guide to dynamic lift speeds in NanoDLP » 2017-07-03 05:34:08

is it possible to handle [[Slowsection]] in dynamic speed?

#23 Re: Tips, Tricks and Tutorials » A visual guide to dynamic lift speeds in NanoDLP » 2017-07-03 04:40:31

would we use some ceil or float before * in equation, could releaf "brain stress" for pi deal with movements?

i think the float numbers would not affect so much when dealing with velocity, in case you working with direct control with dynamic speeds , velocities could influence in rounding errors depending of the driver capabilities. as direct control may have been coded with pulse train, do you think it could improve anyway?
