Cura Takes an Incredible Amount of time to load files

[ethansharp0212 1]

When I try to import files onto the build plate, it takes 10+ minutes for them to load. Does anyone know any fixes to this problem? I'm on a mac, and it's worked just fine up until a few days ago, I've uninstalled and reinstalled it several times, and I still don't know what to do.

What Mac do you have, and what Cura version are you using? Some older Macs will technically run Cura, but in use it can be like crawl Cura.

 

Also how complex is your model? I've created 300MB+ STL files that have taken several minutes to load in Cura even on my high-end PC.

 

And can you think of anything that might have changed at the same time you started experiencing this problem? OS update? Started using a different mouse? You'd be surprised how often seemingly completely unrelated things can mess each other up.

 

You could also try doing a clean reinstall of Cura but move the configuration folder somewhere else on your hard drive instead of deleting it entirely so if it doesn't solve the problem you can restore all your settings just by moving it back.

I do have a pretty old mac, but Ive used it for months without any issues and all the sudden its a problem. I've just tried to slice some benchy files so far. I haven't changed a single thing on my settings in a long time, the only thing I can think of is that I hadn't used it for a couple weeks, but I don't expect that would do anything. I've noticed now that once I wait that initial wait time, files will go in just fine with just a second or two of wait time.

You're not the only one, there's been reports of this before.

The solution someone offered (not sure if it worked) last time (or the time before, or... something):

1. Click Marketplace at the top right
2. Click the gear icon at the top right of the marketplace window
3. Scroll down to the "USB Printing" plugin (it'll be in the Bundled Packages section) and click Disable

Especially if that works for you (although even if it doesn't) you should probably submit a bug report detailing the situation.

That worked! Thank you so much!

Oh Yes ! Thank you very much ! Since I upgrade My Kubuntu distribution and install last version of my favorites software, I have nothing but problems, and to solve this one I had to pull my hair out until I saw this workaround.

 

For God's sake, why not disable this crappy plugin in an updated version, or tell users that if they have a problem, they have to disable it?

I really, really wish they would disable it by default. USB printing is deprecated and no longer supported - it's a leftover from the days when printers were too stupid to even read files from a memory card and had to be hand fed instructions. It's also a lot less reliable (yes, my printer has frozen in the middle of a print... once - number of times my computer has frozen when I've had something printing from a card: many more than once; although even without a freeze, if your computer's CPU is busy doing something and can't keep the flow of gcode commands up to speed, you'll end up with a hot nozzle just sitting there oozing a little bit). I'm not sure exactly how much development has been done on the plugin in the past couple of years but I would guess "not much" at best. There are still some people who run fairly old printers which need to run over USB, but it's very much the minority these days.

 

The problem is that based on the number of the people who come to the forums asking for help with getting USB printing working, are having problems somehow involving USB printing, or have entirely separate problems but it comes up that they print over USB, a lot of people are still doing it. There'd probably be a bunch of people coming here asking "what happened to the USB printing?".

 

Now if you'll excuse me, I'll just go submit a feature request for the plugin to be disabled by default and adding an option to the "Add a printer" wizard saying "I'll be printing over USB" which enables it.

Thank you for the tip. It worked for me. On cura 5.8.1, after clicking on the "Marketplace" button, top right, I had to click on the "Manage packages" gear button to access the installed plugins. I disabled the "USB printing", the Update checker" and all the "Version Upgrade".

Cura work fine again, but does not remember the folder I used in my previous session. I'm on KUbuntu 24.4. Remembering the folder never worked for me.

THANK YOU!!!!!!!!!!!  I thought something was completely borked on my system!  It was taking minutes to load anything. Disabling the plugin fixed it.

Just spent 2 days going thru hell because of this!  Thanks to the poster who tells to un enable the usb printing!  You saved the day!!!!!
