Cant Connect to my Pi

I tried searching but couldn't really find anything.

I wrote the img file to the sd card for my pi 3, installed it and it went through the normal boot up saying everything was OK and then went to a blank screen (hooked up to the projector via HDMI currently thrown at a wall while i figure things out)  I have a network cable connecting the PI directly to my computer (read that I didn't need a router for it) and I loaded the 64bit .exe file and then went to http://127.0.0.1:8080 which brings up a lovely dashboard however when I click turn on projector it takes over the second monitor on my desktop computer which will then display all the calibration images as I click them, I cant direct it to the pi/printer.  I haven't loaded the new firmware or hooked up the ramps to the PI yet as I want to confirm this terminal will work before I change any of that.

The .exe terminal reads:
2017/03/22 12:14:09.323391 {"Layer":"0","module":"Hardware","level":"Notice","msg":"Initializing build # 0 - generic"}
2017/03/22 12:14:09.323391 {"Layer":"0","module":"SLAVE","level":"Error","msg":"Serial port could not be activated The system cannot find the path specified."}
2017/03/22 12:14:09.323391 {"Layer":"0","module":"Terminal","level":"Notice","msg":"Terminal Reader Activated"}
⇛ http server started on [::]:8080
2017/03/22 12:21:54.473515 {"Layer":"0","module":"SLAVE","level":"Error","msg":"Serial port could not be activated The system cannot find the path specified."}

Help!  I know I've got to be missing something..

Re: Cant Connect to my Pi

I moved over to an unmanaged switch and added my laptop to the network which I can now see yet no raspberry pi visible.  I swapped cabled to make sure I had a good cable and no change.

Re: Cant Connect to my Pi

On RPi the screen must go blank as it will be used for image projection so it is fine.
Windows program is totally separate to RPi version. You should use one of the them not both.

You can connect RPi directly to your pc but you need to change both pc and rpi's ip to static.
There are lots of different ways to setup RPi connectivity (wired directly, wirelessly, with managed and unmanaged switch with dhcp without dhcp) I suggest check out muve3d guide on rpi version.

Probably easiest way is to connect your rpi to your home network, and checkout your router/modem panel to see IP or check out windows network area as it broadcast its through upnp.

So the windows version is simply to control the DLP printer through windows?  I guess that makes sense now.

I am just wanting to separate my muve DLP printer from the need of a dedicated computer and be able to send files to it easily via my main desktop which currently just uses wifi (its in a hospital so I cant connect to the wired network with this one)  I want to connect with the printer via a network cable. 

How do I change the RPi ip to static?  would that be in the config file?

Re: Cant Connect to my Pi

It is a general linux question. Unfortunately you need to have basic networking knowledge and follow tutorials on how to setup static ip on bash.
Basic idea is that.
You make your windows ethernet IP static like below:
IP: 192.168.2.5
Subnet: 255.255.255.0

On RPi side
IP: 192.168.2.6
Subnet: 255.255.255.0

On windows it is easier to do. For linux you can follow this one
http://raspberrypi.stackexchange.com/qu … ian-jessie

Where it mentioned       
static ip_address=192.168.0.10/24
You should change it to
static ip_address=192.168.2.6/24

So you can connect to rpi by putting 192.168.2.6 IP on your browser.

If you do not know how to ssh into rpi, checkout guide on putty.

Could I also change the nanodlp_network file on the raspberry pi?
What should I set the gateway to?  just 192.168.2.1?
Ill investigate what you posted, I appreciate the help!

Re: Cant Connect to my Pi

Gateways is not import in your case.
Yes, you can also edit nanodlp_network.
File looks fine. restart rpi.

Change your windows ip to static too.

Re: Cant Connect to my Pi

I saved the settings I posted above and rebooted everything and still wont connect, just times out when i plug in 192.168.2.6 into chrome or edge.  I did notice that the Ethernet connection is labeled as unidentified network and wonder if that has anything to do with it.

Re: Cant Connect to my Pi

Unidentified network issue is related to not having correct gateway which is not important.
Try ping your rpi see if you could see it or not. If you do not see it type ipconfig /all  on command prompt and paste output here.
