Getting a big spool to feed to your S5 ...

Great idea! Is it your design?

Also the cabinet is nice, looks like the IKEA "Alex" which I am also using for my S5. Just be careful that the printer will not fall of the cabinet. I have secured mine that the printer cannot slip off.

Nice idea, just one remark, does the filament touch the power plug? Maybe a situation you would want to avoid. The rubbing of filament can be quit agressive.

 

When the roll gets smaller, it will. It is an unfortunate place for the power plug (hey engineers!). I'll probably print a diverter of some sort eventually.

Well....the roller stand came with the roll. The shelf brackets are from thingiverse. The shelf is a bit of MDF I rounded and painted black. The arrangement is my idea. So, it is sort of my design, sort of not? I think it is Alex, with casters added, because everything in my shop has to roll 🙂

That is a good idea. I really want the back right to the edge to help feeding, but that is a good start. I probably don't worry enough about the printer taking the leap. Thanks!

I just added 2 Ultimaker S5s to my University MakerSpace colleciton of 20+ printers and the Ultimakers appear to be the best so far by a large margin.  I apologize if this is not the correct thread to post my 2 questions but this seems like a well moderated thread and I have not been able to find complete answers elsewhere.  Here goes...

 

Can/how I give the S5 a static IP and I apologize in advance for rehashing this question.  I see references here how to do it but no complete answer.  Also I would prefer to avoid the "why do you want static, DHCP is better?!" discussion.  I live in the uncomfortable world between incredible unbelievably rigid IT professionals (I would love to rant against them here but will refrain) and students, whom if you do not make the solution fool proof, will give up and complain.  I do have my 2 S5s connected via ethernet to a private network via DHCP but they have already switched IPs a few times making things difficult.  I currently have a very cheap WiFi router (acting as a router) giving DHCP to some devices on this pvt network, but I plan to switch this router to AP mode and ideally make everything static at the device.  I do assign all my lab devices static IP (around 50 and I keep a detailed table).  Yes, I realize this has drawbacks but it works for me.  Every other brand of printer I have has a reasonable easy way to create a static IP (some use Octoprint).

 

Second question regards how the queuing function works especially if printers have similar but different filament loaded.  I REALLY like the queuing function of Cura Connect and plan to use it.  I do have 1 printer set at the host.  I would be more than willing to read up on this is someone can point me in the right direction.  Here are my specific questions:

 

-  It looks like only the host shows up Cura although I am getting inconsistent results in Cura.

-  If I slice for a particular filament and send it to the queue what happens if a printer becomes available but does not match exactly the filament?  I know this sounds obvious, but what if it is just color difference?  (color rarely matters to me)  What if the difference is in the 2nd extruder but the job is only 1 extruder?  I know I can probably just test all of these features out but it would be nice to know how Cura is handling them.

 

Thanks in advance, so far so good.  I now know why a colleague of mine has gone exclusively with 50+ Ultimakers in his lab rather than my mix.

I found, with windows as the host, I could only get reliable connection via Cura by using a set IP (Preferences | Printers in the network settings). Windows+Cura could not reliably discover the printer otherwise. Of course, the DHCP settings can make it difficult to know the IP address beforehand. I solved it by reserving the IP in my DHCP server, but of course this is not available in all environments. In your setup your cheap router should allow this; once you get rid of it, you'll be in more trouble 🙂

The described steps from this thread seems to be the complete answer - at least it worked for me on the UM3

(but i don't know if the developer mode is available on the S5 as well?):

Thank you for the understanding!!!  I completely agree and do not want to start a static/DHCP argument but I feel that some situations lend themselves to static and some are fine with DHCP.  I have found that I have continual problems discovering printers when going DHCP, but I will also admit that my situation is unusual and potentially not optimal, but bottom line static just works for me.  I looked around my router interface and did not immediately see a way to give the Ultimakers a static IP and I plan to shift my router to AP mode very soon anyway.  I only use this cheap router as a way for students to WiFi directly into the pvt printer network.  Ideally it serves no other purpose.

Thanks for this as well.  I did see this post during my first review but I saw things like "ugly workaround" and people seemed to indicate that this process was difficult so I shied away from it; however, if it is just using SSH and simple commands lines, I am willing to give it a shot.  I have a feeling my next question is going to be how to factory restore an Ultimaker 🙂

 

All of this is pretty time critical (for me).  My MakerSpace came crashing down this week - mostly due to other printers - so I need to completely reconfigure the whole lab this weekend or my Monday at the latest.

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
