He, 4.1 beta BOOT is so so slow with my HP spectre I7 6500 computer CPU 2500 - 64bits 8Go win 10 kind regards

fieldOfView commented 5 years ago

Without logs, or even a mention of how slow is so so slow, there is fairly little that can be done here. Did you try other versions? Are they less slow to start?

Ghostkeeper commented 5 years ago

I wonder what phase of the start-up is taking so much time then. Creating the interface? Loading machines?

I'm also wondering if renaming the C:\Users\<OUPS65>\AppData\Roaming\cura folder to cura-backup (while Cura is closed) helps in any way with the start-up. This resets Cura to factory defaults. You can delete the new cura folder afterwards and re-name the backup back to cura (while Cura is closed) to restore your settings.

@fieldOfView : 4.1.0 takes 30' to be ready to use when 4.0.0 need only 17'. do not understand what you mean by " without logs". connected to my ultimaker account or not do not change the delay. @Ghostkeeper : both creating the interface and loading machines where slow . After this factory reset,, I have only created the Anycubic I3 printer... and YES ! 4.1.0 now needs only 12' .
If I re-add a non-networked printer, with original Prusa profiles, I am still at 12' even if I import one personal 4.0.0 profiles on top of the original Prusa one. connected to my account do not impact. Adding "customs support", "linear advanced setting", "mesh tools", "setting guide", "version in tittel bar", "Z offset setting" add 3' on the start. kind regards.

PS : could be very helpfull to have the nozzel size setting displayed on the screen

Ghostkeeper commented 5 years ago

Maybe you had a lot of printers added and that was making it slow?

We display the active nozzle profile in the main screen, which is usually named after the nozzle size. If your printer doesn't have different nozzle profiles it displays nothing. I think that's something on the part of the maintainer of the Anycubic or Prusa definitions, whichever you were using.

Hi,

Cura 4.1 is also very slow on my MS Surface Pro 4 (i5, 8GB Ram). My only Printer (Anycubic i3 Mega) is connected via OctoPrint -- which is the only extra plugin on my setup.

fieldOfView commented 5 years ago

Please quantify "very slow". Also, what is slow? Only starting Cura, or changing settings, or drawing the 3d viewport?

Is it also slow when the OctoPrint Connection plugin is not installed?

trunneml commented 5 years ago

Mouse hover effects in the menu are not shown or 2 seconds to late. Typing in text fields is delayed by seconds. The problem existed directly after a fresh installation without any extra plugins.

Ghostkeeper commented 5 years ago

Does not happen on my old MacBook Air (also i5, 8GB RAM). Cannot reproduce.

What is different about the MS Surface Pro 4 that would cause it to be slow? I would think it has an SSD as well. Perhaps the difference is Windows vs. Ubuntu?

Version 4.1.0 platform : HP spectre I7 6500 computer CPU 2500 - 64bits 8Go win 10 printer : PRUSA MK3S I re-installed Cura using the profile MK2 and not anymore the profiles received from Prusa. Everything works now perfectly and I have impeccable prints.

about nozzel size information on the screen I regularly change nozzle. I would like to see on the screen what diameter is in the setting of the printer EVEN IF I only have one nozzel on the printer :) tks

4.1 beta was slow at startup for me, but it seems the problem disapeared with 4.1 release version...

about nozzel size information on the screen I regularly change nozzle. I would like to see on the screen what diameter is in the setting of the printer EVEN IF I only have one nozzel on the printer :) tks

just create a printer for every nozzle diameter, with the diameter being part of the name. "printer 0.3", "printer 0.4" and so on. Works fine for me. But the printer name is not displaed in Peview mode...

Hmm, so you think the MK2 profiles were causing this? Where did you get those profiles?

I'm starting to think though that maybe this was caused by a plug-in that you had installed. Those are generally more powerful in what they can cause in Cura.

On the issue of slowness, switching from 4.0 to 4.1, a model which under 4.0 would print 1X amount of time. The very same model (using the very same printer and material settings) under 4.1 takes 3X time to print. I noticed the hot-ends would print then pause, then print, then pause, etc. I have no idea why the slicing is so different in 4.1. Until the slicing is fixed, I will be using 4.0

Ghostkeeper commented 5 years ago

@tkocou If you're talking about an Ender or Tevo printer then it could be that the jerk was set to be lower because people were experiencing layer shifting issues. It is intended, then. It is also a different issue than the front-end performance that is being discussed in this topic.
