Developer mode documentation

Hi everybody,

Is there any documentation for the developer mode of Ultimaker 3?

I use Linux all the time, but the Linux version on UM3 does not let me do much, at least, I don't know how to use it. I only found a post from @Daid ( https://ultimaker.com/en/community/23428-inside-the-ultimaker-3-day-5-developer-mode-linux-systemd ) which I could not use it.

My problem is that after I ssh to the 3D printer, I only have few limited options: (exec, exit, get, help, list, select, set, and sendgcode). I don't know how to actually run Linux commands there. For instance, right now I am trying to set a static IP for my UM3. I know how to do it on a desktop distribution of Linux, but I cannot run any similar command on the version of Linux installed on UM3.

I think the key point is: login as "root" (same password as the ultimaker user). Good luck, and if you've managed the static IP thing... a step-by-step docu would be very nice... :)

If its really is Debian (jessie build), then static IP assignment might be as easy as:

 

nano /etc/dhcpcd.conf

 

Then add these lines to the bottom:

 

interface eth0static ip_address=192.168.1.3/24static routers=192.168.3.1.1static domain_name_servers=8.8.8.8 8.8.4.4

 

interface is what's connected to your network (eth0, wlan0, etc). Use:

 

ifconfig

 

To see which interface name has an IP address.

static ip_address is what you want to assign to your Ultimaker (you'll usually keep the /24 netmask)

static router is the IP address of your router.

static domain_name_servers is optional if your router doesn't provide them, or you want to use specific ones (these are Google's)

P.S. Another option is to set your router to assign a static IP address for the Ultimaker based on its MAC address. Then you don't have to muck with the guts of your printer...

Thanks ... This solved my issue in the connection and running linux commands. It is weird that it was not mentioned anyplace online to do that.

I will try this approach tomorrow. If it works, I will share it here.
