[How to set IP address without WiFi or DHCP]

Not to sound harsh, but I rather work on the solution so this works for everyone. (I'm the guy in charge of firmware at Ultimaker)

Got a few questions, the setup you need, is that static IP configuration on the cabled connection, static IP configuration on the WiFi connection.

Or, even dynamic configuration with a static gateway? And then on WiFi or LAN?

(Maybe you have some IT instructions that you can copy&paste without passwords)

I'm asking these questions to make sure we build the new static configuration feature in a way that it can support your network configuration. As it is a bit unclear to me what exact needs you have.

 

Hi @Daid,

My suggestion is to use the same network settings procedure as regular printers (paper and ink). Having a printer on the network has been solved long ago. Usually, IT guys know how to make their network settings ready to support regular printers on it.

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 eth0
static ip_address=192.168.1.3/24
static routers=192.168.3.1.1
static 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)

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

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...

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.

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.

[Manual control for Ultimaker 3 over the LAN or wifi]

This was my first time posting in this forum and I am amazed by your support. Thanks for all the replies especially to @neotko and @lndy31 which helped to solved the issue that I had.

I'm curious to hear for what serious applications you are using the manual control.

I am doing a research on statistical modeling of cyber-physical systems such as 3D printers. I need manual access because I want to accurately synchronize the data that I am collecting from the 3D printer with the instructions which are being executed on it.

If you like to learn more, you may take look here:

This is what we did with a 3D printer couple of months ago.

[Manual control for Ultimaker 3 over the LAN or wifi]

Hi Everybody,

I like to have manual control on my UM3 over the wifi or LAN. On my previous 3d printers I was able to connect to the printer using Repetier-Host via serial port. After the connection was established, I was able to send gcodes and monitor the response of the 3D printer. But, UM3 does not support serial connection. Do you have any idea how can I manually control it?

Thank you very much in advanced.
