Lasers not working, Usb not written to... (Page 1 of 2)

I'm happy to replace that part if needed, that's strange - I haven't seen the laser just skip a cutout like that before.

I sent an email with a couple things to check about your SD card, let me know if that helps.

Hi betoarango,

The scanner software is indeed running and you should be able to access it on port 80.  Your kit was ordered before the release of the software update that performs the USB network configuration.  You can still use the command line to configure the WiFi adapter as shown in the instructions below.  Once you have a network connection, you should use the auto-update feature present in ATLAS 3D to update to the latest version of the software.

You can do either way, whichever you are more comfortable with. I would suggest trying the command line instructions just because it is highly likely at some point you are going to carry out some instruction from the command line so its a good skill to have. Learning new things is what raspberry pi's are all about!

If you want to remove the SD card, you will need a PC running linux (or maybe a mac?) to access it on. Windows wont understand the file system. You would then navigate to the file /etc/wpa_supplicant/wpa_supplicant.conf and open it in a text editor and make it look like this:

ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1

network={
        ssid="YOUR_SSID"
        psk="YOUR_PASSWORD"
}

Alternatively from the screenshot you posted earlier I assume you have a monitor connected. If you also plug in a USB keyboard you are good to go.

Pressing <enter> from that screen it should prompt you for a login, so type

pi<enter>

It should then prompt for a password so type: *note your password characters are not displayed on the screen!

raspberry<enter>

And then you should get a prompt which looks something like:

pi@raspberrypi:~ $

Which means you are successfully logged in!

From here you then type:

sudo nano /etc/wpa_supplicant/wpa_supplicant.conf<enter>

That will open up the file we want to edit in a simple text editor. You can then make the changes as described in the Atlas3D instructions. To exit the editor and save your changes press:

<ctrl>x
y
<enter>

And then restart your pi by typing:

sudo reboot<enter>

Nice work! Making progress.

It looks like the wifi configuration didn't work. That stuff about "daemon failed to start" means something went wrong somewhere.

The IP address 127.0.0.1 is just your local loop back address so that wont work to connect to your Pi over the network. Likewise 255.0.0.0 is a netmask which is something different again. When you get it working you should see an address like 192.168.x.x or maybe 10.1.x.x depending on how your home network is set up.

What wifi adapter are you using?

First check, login and type this and see what you get.

lsusb<enter>

For my setup I get:

pi@raspberrypi:~ $ lsusb
Bus 001 Device 002: ID 0bda:8176 Realtek Semiconductor Corp. RTL8188CUS 802.11n WLAN Adapter
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

So that shows that the Pi has found my wifi dongle and knows what it is.

Sorry I should have posted this link before. I'm just going through this procedure here: https://www.raspberrypi.org/forums/view … mp;t=44044

Next step is to see if the driver is loaded:

lsmod

Then see if the network interface is there:

ifconfig -all

Raspbian is an operating system for the Raspberry Pi based on the Debian distribution of Linux. I assume that is what is running on your Atlas3D SD card though I dont actually have an Atlas3D so not 100% sure.

The lack of modules shown with lsmod is very strange, it might be time for someone with more experience with the Atlas3D image to chime in, but to me that doesn't look right.

After a quick search it seems others have also had trouble getting wifi working on the Atlas3D image, perhaps you have a simiar issue to this: http://www.soliforum.com/topic/12209/wifi-not-working/

so there was some sort of problem with the sd card.
elmoret sent me a file, and showed me how to image burn it into an sd card, the pi turned on...lasers flickered got the murobo login program...
inserted it back into the pi...

howver it still seems the pi does not see the dongle as a wifi adapter...

so it might be that C_Ds suggested topic might be also my problem...

however I naively opened the pi webpage explaining what to do...

You must be kidding me... 
really you must be kidding me....

Am I on TV? 
Is this some sort of show....

Hi betoarango,

The Pi sees your WiFi adapter and has loaded the correct driver for it.  The 8188eu in your lsmod output is the loaded WiFi adapter driver.  The "0bda:0179 Realtek Semiconductor Corp" is it showing up on the USB bus.  The problem seems to be either wireless signal or password related.  Is the scanner close to the WiFi access point?  Does your password consist of all alphanumeric characters? Also, are your lasers coming on now when you insert a USB flash drive?

On an unrelated note, you may want to check the connection of your motor wires.  The black one looks loose in the photo.

Tried looking in other Raspberry Pi support websites and one of the reccurent suggestions was the use
of  a 9v  charger as opposed to my current 5v 2amp wall wart.
I will give this a try tonight, see if my problem stems from a lack of juice...

totally correct.. looks they were coonnecting this through a reducing voltage regulator... 
thanks for the save...

just googled it and my cellphone does have the option to allow my hotspot  to connect to any device (I assume without password).. I will test it as soon as I get home.

You have no idea how over my head I am on this....

Also just became a member... as opposed to newbie...

Was unable to remove the pasword from my hotspot...

Turned on the adtlas3
Inserted the wifi dongle(also tried the exact procedure with the wifi dongle preinserted)
inserted usb
lasers turned on, turned off 5 secs or so later
removed usb
inserted into my win10 laptop (also into my winxplaptop and win8 desktop)
beto-red-note (my hotspot was one fo the options available, also tried it for my home wifi)
chose it
updated password, saved, ejected usb correctly
just for laughs turned on my laptop, erased the wifi... reconected using same password...
reinserted usb into 3d
lasers turn on for about 30 secs then turn off
remove usb put it in win10/winxp/win8 computers
get...

bang head on desk...
repeat...
