When the object is sliced and the gcode created, what is the speed setting in the gcode? Is the speed something I can modify in the gcode? I ask because no matter the speed I select in CURA, the prints are always printed at the same speed. To reduce the speed I have manually reduce the print speed on my machine.

Isn’t %APPDATA%\ usually a hidden folder, which would need to be unhidden Control Panel -> Folder -> show hideen files/folders?

The board has multiple threads about cura 3.1 issues, perhaps it should be pulled, and beta tester released. So my advice is uninstall 3.1 and go back to a version of cura that worked for you.

Please see the video here , that video demonstrates the issue. The slowness is not about layer view, the slowness when you change a custom parameter, it will take 6 to 7 seconds before you can change another parameter. This slowness with changing parameters happens even with auto slicing turned off. One hypothesis is that when a change is made to one custom parameter, a software change is made to other parameters with the intent of reducing the slicing time.

I wish it were that simple for me.

Would it help to narrow down the issue(s) by focusing on the overall sluggishness? It takes almost a minute for cura 3.***** to fully open. Then without a model loaded, there is about a 7 second delay between mouse clicks and cura response.

I have AMD processor and experience the same sluggish issues, on board graphics card is ATI Radeon 3000. Just installed a new video card 30 minutes ago, and still have the same sluggish issues.

I thought about asking about Apple bonjour as I have seen that process in Task Manager on my other system As for why I did not pip install pybonjour....because I haven't the slighest idea of how to do that, nor where to do that. At the moment I suspect that it would be: cmd prompt and then get into the venv c:\octoprint pip install pybonjour So I ended up with this: (venv) C:\octoprint>pip install pybonjour Collecting pybonjour Could not find a version that satisfies the requirement pybonjour (from versions: ) No matching distribution found for pybonjour I will try apple. But there is another issue, which I suspect has to do with granting network access.

I also experience the slowness on a win 7 laptop with 8gb of ram, Not sure of the graphics card. The laptop is Intel based, and was slower than the desktop with win 10.

based on the lines in the cmd prompt it looks like pybonjour did not install with python. 2018-01-09 17:05:29,582 - octoprint.plugin.core - INFO - Loading plugins from C:\octoprint\venv\lib\site-packages\octoprint\plugins, C:\Users\***\AppData\Roaming\OctoPrint\plugins and installed plugin packages... 2018-01-09 17:05:30,221 - octoprint.plugin.core - WARNING - Plugin "OctoPi Support Plugin" did not pass check 2018-01-09 17:05:30,285 - octoprint.plugins.discovery - INFO - pybonjour is not installed, Zeroconf Discovery won't be available When I attempt to manual install pybonjour I get (venv) C:\octoprint>pip install https://goo.gl/SxQZ06 Collecting https://goo.gl/SxQZ06 Using cached https://goo.gl/SxQZ06 Cannot determine compression type for file c:\users\***\appdata\local\temp\pip-gucorm-unpack\SxQZ06.obj Complete output from command python setup.py egg_info: Traceback (most recent call last): File "<string>", line 1, in <module> File "c:\users\***\appdata\local\temp\pip-imxrxv-build\setup.py", line 32, in <module> import pybonjour File "pybonjour.py", line 88, in <module> _libdnssd = ctypes.windll.dnssd File "C:\Python27\Lib\ctypes\__init__.py", line 435, in __getattr__ dll = self._dlltype(name) File "C:\Python27\Lib\ctypes\__init__.py", line 365, in __init__ self._handle = _dlopen(self._name, mode) WindowsError: [Error 126] The specified module could not be found ---------------------------------------- Command "python setup.py egg_info" failed with error code 1 in c:\users\***\appdata\local\temp\pip-imxrxv-build\

Terrific for you. But a complete pain in the backside for those it affects. Shortly after this thread was created another thread was created addressing the slowness of cura. So it is problem for multiple users.

I have not tried disconnecting from the internet. But yes, Cura initial startup take about 1 minute and 40 seconds for me.

Did you turn OFF automatic slicing? Turning that off only helped a small bit. Cura still bogs down with every mouse click, even when a model is not loaded.

I will speak to conclusion 1. Here are my specs: AMD Athlon IIX4 640 Processer 3.00GHZ 8.00GB RAM (7.75 usable) 64-bit operating system, x64 based processor Win 10 Pro (authenticated) Cura take 1 minute and 40 seconds to fully open. Auto slicing is disabled, NO model is loaded, and it takes 7 seconds between any change in an parameter under custom before another parameter can be changed. So I agree with you that Cura runs slow

If Ultimaker cared about its products and the users, then ultimaker would provide instructions To your comments I identified the problem in the first post. Specifically “and then get some message about selecting an instance and some message about host, ports, paths....What in the world does any of that mean?” As for having to manually add, There is Instance, Host, Port, and something else. Yet I cant find anything about manually adding an instance, that does not first assume the user is using rasberry pi.
