Cura running super slow on a really good computer

Recommended Posts

Posted · Cura running super slow on a really good computer

I have had my laptop for a few months now. It is a gaming laptop that has an intel i7-8750H processor with 16G of RAM and a GTX 1060. It runs Fusion360 like a champ, and can game tremendously well, but for some reason, Cura runs super slow. Anytime I try to adjust the settings for a print, every drop down men I open takes several seconds to open, and when I orbit around the object I am trying to slice, everything is always very laggy. It didn't do this when I first downloaded Cura, but for some reason it is doing this now. Does anyone have any ideas on how to fix this?

I experience the same when opening a drop down menu in the advanced print settings. The settings appear slowly one after another. Tried it on a few different machines (Workstations and laptops) and there is no difference. So maybe it's a general software bug.

It's not a general software bug, since that would never have cleared QA on our side. For me it takes less than 2 seconds for all settings to load on boot and drop down menus open in 100 ms or something like that.

None of this happened when I first started using Cura on this computer. Could something in my computer be limiting its performance?

Actually now its back to working correctly. Its lightning fast. The only thing I have changed is my wifi connection. I changed to a network that works better. Could this have been the cause?

Hm, maybe my maschines are just crappy. I will take a look at the network settings also.

I think I figured it out. I was looking at some forums about internet slowing down cura, and apparently cura tries to connect to web printer servers like octoprint. I am on a large wireless network because I am a college student using dorm wifi, so Cura was trying to find all the wireless printers on the large server (there is none), thus slowing it down. I just went to the plugins and deleted the one that has to do with wireless printers. C:\Program Files\Ultimaker Cura 4.2\plugins and delete the one called UM3NetworkPrinting. That instantly fixed the problem, and I dont use wireless printers. If I ever do, I'll just reinstall cura or something to get all the proper network plugins back.

It's not trying to connect to all of them, but it is listening to broadcasting messages (It's a fairly important difference. The first is actively contacting every single IP to check if it's a printer, the second is waiting for someone to shout "IM A PRINTER").

 

Alternatively, you can also just disable the plugin in the marketplace. You can do this in the installed tab.

I turned this plugin off too and it really makes a difference, much better now. 
I am also on a large network (company).
