nanoDLP

Im a bit confused by your latest post !  " Does it matter if i have steppers instead of servo"
You only need 1 stepper and it is to drive the Z axis.
A servo can be used for the shutter and maybe a tilt/peel function if you have it.
If you are using a ramps board you should remove the stepper drivers from X ,Y E0 & E1 as they have no function Just leave Z ( of course)
If you want to test your ramps in stand alone mode you can upload the test firmware to see which axis are working and which not.
You can get the Ramps test firmware here  http://reprap.org/wiki/File:RAMPS14_test.zip
WHen loaded it basically runs the stepper motors backwards and forwards and pulses the extruder heater and bed output without any input needed from the user.
Very useful as a quick way of seeing if your ramps board ( and stepper driver chips) are working ok
Good luck

You are forgiven ....Im 57
And forgive me if im telling you something you already know !
The screen should go blank after NanoDLP installs . It is what is commonly known as a headless install = it does not support a screen attached for OS info ( of course it later drives the HDMI output to a DLP 3D printer) It is only accessible via a web browser.
To be honest i have never installed NanoDLP on a working Linux distro I always use the "pre installed" ISO  I then hook up the Raspi to power and my network with a Cat5 cable Then I access my router to see which IP address the Raspi has been given ( assuming your router is using DHCP)
Then use that IP address in my browser to access NanoDLP
You need to allow enough time for it to install completely ...
Good luck

Basically the GRBL/ Nano is a basic ( and still very versatile) simple cheap CNC / Gcode solution

Really easy to set up and configure via terminal -  It has end stop feed back and the ability to turn ON/OFF a couple of outputs ( tool and coolant if i recall correctly) that you can use for LED / shutters ect

I can see what you mean with a Ramps being over kill BUT it does every thing you need and by not using the heater elements even the clone ramps reliability improves a lot

The quickest way is to look at your modem/router/wifi access point and see if the Raspi3 is connected and if so which IP address it has been assigned.
To see if the Raspi is working just connect it directly with a Cat 5 cable

Good luck

You are welcome. If you can be patient i will help you when i have had time to get this working on my machine

Hi You don't need to do either A or B You can simply use the Raspi HDMI to the Screen and a Raspi usb port to the KLD 1260 controller board serial connection.

Leave the original KLD 1260 controller in place ( MKS 1.1 pcb) so it can drive 1/ the stepper motor 2 / Drive the LED power ON / OFF & 3/ Managed the Z ( home position) end stop.
NanoDLP works fine controlling these 3 functions via serial communications

WHat you do have to do is configure the Raspi to output the correct resolution on its HDMI port and that is what is being discussed on the forum thread >>   https://www.nanodlp.com/forum/viewtopic.php?id=305

Could you please post a link to the utility and maybe post your config.txt files.

I will be attempting this next week and it would be great to see how you managed success

Thanks

Thanks for posting .Great timing and you have saved me a ton of time by posting the HDMI config

Really interested to hear how things develop getting this all working

Cheers

Thanks again for the reply
CLearly i need to do some more research on this . Ill report back when i know more

Cheers
