Cura prints always fail

I am having the weirdest damned issue. If I slice in Cura, it will always fail when printing. It's like it loses connection. Printing just... halts, with commands waiting. I've tried different USB cords, different laptops, different USB ports on those laptops, always the same, and always ONLY with Cura prints. I can slice and print the exact same item with similar settings in Slic3r and it will run fine, with the exact same hardware setup. This is happening with various versions of Cura, not just the latest one.

The obvious solution of "Just use Slic3r because it doesn't fail" isn't always going to work for me: right now I'm having slicing issues where it's making the entire top half of my model completely hollow, and I'm too dumb to figure out Skeinforge.

What the hell is happening that it keeps failing? Any ideas?

 

I had this issue recently too and had no idea what was causing it. it started happening when i updated cura to 14.03 so i just moved to LCD and it stopped happening.

If you use LCD: have you safety removed the SD card? the GCODE might corrupt if you remove it too soon.

If you use usb: there may be programs overriding the usb for a moment like a background antivirus scan.

tip* i also find if i plug something into the wall with the printer, it will stop printing. Do you have a stable electricity supply or do you share it on an extension cord?

Good luck!

 

Yeah I'd like to print from SD but I'm not there yet. Upgrades won't be happening for a while, unfortunately, so I'm stuck with USB.

I don't have any antivirus on either of the laptops I've used, and they've both been trimmed down to only the necessary things running... I'm not sure what would be overriding the USB, but I can give the processes a look over again, I guess. The power supply is stable, nothing being plugged or unplugged/turned off and on, and it's never been shared with anything else, nor had problems when I was running a space heater that would cycle on and off (not on the same outlet, but on the same, umm... circuit? Control switch? Thing? idk the word), so I think the power in that room is okay, stability-wise.

It's just weird because I can print for 18 hours straight with a Slic3r print with the same stuff running, not even a reboot or anything, just loading different gcode, and switch to a Cura print (both printing from within Repetier) and it fails within an hour or two.

 

it may be a faulty document then. try slice with cura and run the g-code through repeteir to see if it makes any difference.

 

Run it through... how?

 

open the g-code on repetier and print from repetier to see if the print stops in the same place.

 

soupaboy - That's what I've been doing. I always print from Repetier, whether I generate the gcode in Slic3r or Cura.

mark - Hmm, so have you found Simplify3D worth the price? It's got a lot of really neat features but damn it's expensive... Been reluctant to get it because of the steep price, but if it's worth it...

 

hmm Have you tried uninstalling and reinstalling cura? it may have updated recently and something went wrong

 

... well Mr. Turvy just went and bought me a copy of Simplify3D soooo I guess I'll try that! lol

 

nice, ask if he will get me a copy

 

Only if you let him touch your boobs.

 

tempting...

 

Now that you have Simplify, it won't matter (I hope), but I couldn't get Cura 14.03 to work either so I went back to the previous version and have been getting great results. Nice work on your faces, Ms. Turvy - and nice job on Simplify for the little lady, Mr. Turvy.

 

Version 1 of Repetier is meant to natively support Cura so hopefully that works better.

 

Oh my sweet baby cheeses. The automatic and manual supports are like a dream of hot cinnamon buns. Also, the speed scaling and just general gcode output is -magnificent-. Way, way more accurate with no ghosting or wobble. Still have yet to see how it does on a larger print, but I've got one running now that's looking really good. It also doesn't choke on slightly wonky models the way Repetier does, similar to Cura (which is most of why I was using Cura).

So I guess the conclusion is... suck it up and buy Simplify3D because AMAZING. Still gonna need some tweaking and fiddling but it seems to be a vast improvement.
