No, not quite. M280 P0 S160 ; BLTouch alarm release G4 P100 ; delay for BLTouch G28 ; home G29 ; auto bed leveling M140 S{material_bed_temperature} ; start heating the bed to what is set in Cura M104 S{material_print_temperature} T0 ; start heating T0 to what is set in Cura Feel free to change the order, but the idea is that the {material_bed_temperature} (as is, including curly brackets) gets replaced by Cura.

Cura looks for neither M109 or M104, it looks for the text {material_print_temperature} (including curly braces)

CuraEngine adds its "hidden" gcode (as you call it) heating up your bed and nozzle because Cura does not see you adding your own. As soon as you add the string "{material_print_temperature}" somewhere in your start gcode, Cura will know it does not have to add it by itself. Same with "{material_bed_temperature}".

I would appreciate it if you could help me test this version: http://files.fieldofview.com/cura/OctoPrintPlugin-v5.0.0-2019-01-28T16_19_16Z.curapackage This new version has a checkbox in the "Connect to OctoPrint" dialog that will let you disable automatic discovery of local OctoPrint instances. If you uncheck the checkbox at the bottom of the list, the plugin should stop all bonjour/zeroconf activity.

The jobname is normally derived from the first loaded object. But you can manually change it (lower left corner in Cura 4, lower right of the viewport in 3.x).

With the right driver, the Radeon HD 4000 family should support the OpenGl functionality that Cura requires.You could try an older driver (instead of the latest one), in case the latest one available has a bug. But you are treading unknown territory.

Afaik, there is not something obvious

Then do that. Ultigcode (or “Ultimaker 2”) gcode flavor is not compatible with usb printing. Never has been, never will be.

Cura crashes while accessing your gpu/graphics card. What sort of gpu do you have? Have you tried updating the drivers for your gpu?

How about, instead of showing the selected printer name, it shows the current job name? With the printer prefix, it "sort of" includes the printer name too. And it is mostly how other applications behave.

Did you change the Gcode flavor to "Marlin" in the Machine Settings?

Note that running multiple instances of Cura simultaneously isn't really recommended. If you make changes to settings, only the changes of in the last Cura instance you close will be stored; the rest can be overwritten. It will work in some cases (eg if you really only use a single printer configuration in each instance), but generally it is not a great idea.

I think so too, I just wanted to help you out with the icons. You might want to at least read through this page, because it contains a link to a plugin that rearranges the new UI so it has a sidebar like older versions again.

Yes

They are the category icons for Support and Buildplate adhesion respectively, showing whether supports and a brim/raft are turned on.

I don’t think there’s an official way to distribute post processing scripts through the marketplace. @ctbeke, thoughts?

A newer version of the plugin is available further down the thread from where you have downloaded it:

I will add an option to disable bonjour/zeroconf discovery of Octoprint instances in a future update of the plugin. I’ll see if I can get a similar option added for UM3NetworkPrinting in a future Cura version.

Heads up: once Cura 4.0 beta 2 launches, there will be an updated version of this plugin (hopefully through the official Marketplace).

Cura 2.6 is a fairly old version. Do you mean Cura 3.6?

I have linked to this before, but here it is again:

Have you tried lowering the other two screws? Then you should have more effective "travel" on the front-left. It could be that the front-left spring is starting to loose its springiness. You can test this by switching the front-left spring with the front-right spring.

AFAIK, nothing major is changing in the interface for Cura 4.0. The settings floater will be resizable (so you can see more settings at the same time), but that's about it. My plugin will likely be available from the Marketplace by then. But you don't have to use Cura 4.0.

@Asger-P you could try my plugin, which restores the notion of a sidebar and rearranges some other functionality:

I think you might be using the OctoPrint Connection plugin. Please check the MarketPlace to see if there's an updated version of that plugin available. If not, please uninstall and reinstall that plugin.
