Hi I use auto bed levelling by calling G29 in my "start G code" and it works like a charm. I have a 300 x 300 bed and I probe 6 x 6, in other word it is 36 times, that the Z axe will move over the same part of the lead screw, for every print I do, this will over time, mean wear and tear on that part of the lead screw, after all it is just brass on stainless steel in most cases. My suggestion is that Cure create the G29 command so that only the area that is used for printing is probed. To extra printer settings is needed: Use Auto Bed Levelling Grid Size For Bed Levelling G29 have a lot of extra parameters so I believe it's already possible. Hope You will consider. Thanks for a great slicer. Best regards Asger

Cura Menu -> Extensions -> Post Processing -> Modify G-Code

It does display the Z height, at least my Ender 3 does, but you can have a look st post processing, there is a script called: Display filename and layer on LCD, I haven't tried it though.

Yea, I forgot, thanks.

I did not say that you shouldn't do that, I said: that it doesn't make much sense to prime the extruder before bed leveling. It should happen as the last thing in the script, just before it starts to print. Ooo! I now see that it doesn't matter at all because your extruder isn't hot yet, so the line of code won't actually do anything except make the extruder grind on the filament, unless of course you preheat it using the menu system.. You need to heat up both the extruder and the bed with code like this: M140 S{material_bed_temperature_layer_0} ; set bed temp M104 S{material_print_temperature_layer_0} ; set extruder temp M190 S{material_bed_temperature_layer_0} ; wait for bed temp M109 S{material_print_temperature_layer_0} ; wait for extruder temp When everything is hot you can level the bed and you can then prime the extruder. First check that the bed actually is the size that it is set to in the printer setting, if so then you can adjust the center in the extruder setting using x and y offset, negative values moves the center to the right and to the back.

Quote from the G-Code manual: The X, Y, and Z parameters act only as flags. Any coordinates given are ignored this means that these three lines: G28 X Y G28 X0 Y0 ;move X/Y to min end-stopsG28 X100 Y100 ;move X/Y to 100X100 Will do the same the same. You can find all the G Codes and what they do here: https://reprap.org/wiki/G-code The Start G-Code does not effect what Cura see as the center of you build plate, that is set in the Printer settings. In Preferences->Printer->Machine Settings->Printer there is a setting Called Origin at center, that one have to be unchecked if your 0,0 is in the front left corner of the build plate, (you see that when you home the beast). Another thing is that it doesn't make much sense to prime the extruder before bed leveling, that filament will just ooze out during the leveling process. Best regards Asger

Hi ahoeben Thanks for your advise, that will come in handy. It would be nice though, if it was possible to copy an already existing printer, so I only have to make some changes. Are there some setup files that are editable (json, xml, ini etc.)? P.s. what is the link about ? Best regards Asger

Hi ahoeben Thanks for your answer. The benefit of doing it my way is that everything is set at once both printer and material, so I don't have to concentrate on setting up. And I don't have to concern about Curas questions regarding settings I changed, which I find difficult to understand, English isn't my main language. Unfortunately the post processing isn't saved with the project only with the printer, although it almost always is used per project. e.g. temperature towers for testing material. Forgetting to delete such scripts can really make a mess. 😉 Post processing the only thing I do have to check every time. 😞 Cura is the greatest, thanks. Best regards Asger

Sure, here they are, the small one comes first and it doesn't remember my choise. Best regards Asger

Hi I would like to run several instances of Cura, one for each of my printers. I try doing that by saving a project with settings for each specific printer, I then call them like this using a Windows Shortcut: Cura.exe Ender3_PETG_0,16.3mf Doing so works, but i get two dialogs that I have to answer before Cura continue loading, so my question is: Is the some options / parameters I can use on the command line in order to make Cura just load the file as I want it done. A full list of command line options would also be nice. Thanks in advance Asger

That is sad, as there is plenty of room in the items for a larger font, much easier for the eyes.

There is a scaling bug in Cura 4.0 When you use 125% font size on windows the settings panel are not scaled correctly, the font is smaller then in 3.6. You don't need to increase the item height, but I would prefer that the font was bigger. Picture shows 3.6 to the left an 4.0 to the right (windows 7 pro 120DPI) Thanks in advance Asger

And where do you find that ? I cant see it in the marketplace in cura 4.0 Found it under: Post processing -> Modify G-Code -> Add a script

You could also get into the habit of turning off the screen manually, when you leave the computer, instead of letting Lubunto do it for you. Just a suggestion. 😉 Best regards Asger

Which version do I need to download, the one that seem to be the latest ? https://www.dropbox.com/sh/s43vqzmi4d2bqe2/AAAF232ISfhlamx53I9bPJ10a/Cura-mb-master-win64-20190118.exe?dl=0 Of course not always, but minimising travel is always good, the result do tend to get better. Cura 3.6 is way better then 3.51 One thing that should be avoided though, is going back over a finished surface to fill tiny gabs in the corners, they should always be filled either first or during the closest print. No it was because 'Max Comb Distance With No Retract' was set to 0, for some reason that setting wasn't visible in my settings window, it is now set to 3 and that helped a lot. :-) Thank you very much. I don't know , because I don't know how to make Cura slice that way.:-) Anyway now that no material is missing around my holes, I'm not so sure anymore. Thanks for all the good info Cura is great.:-) Best regards Asger

Hi Ahoeben Thanks for your suggestion, but I have uninstalled Cure 4.0 again, hoping for a much better final release. :-) Best regards Asger

1. It isn't infill although it is affected by the infill settings, because if i set infill to 0% the wall will be hollow, but at only 1% the wall is totally filled with a 45° pattern (see first pic) stressing the printer a lot. Changing the line direction have no effect when printing a square, it will at best only fix half the problem. 2. That will just remove the stringing problem, the reason for my suggestion is the material that is missing after a travel, the material that produced the string. This missing material is weakening the printed part (see pic2), the material missing around the hole is after travel. 3. Makes sense, but you could count the processors and the divide the layers between as many threads reducing the between layer travel a lot. 4. The slicer seem to print finish each kind of print on a layer before starting on the next kind, outer wall, inner wall, infill.. See Pic 3 It starts the hole at the red dot ends at the blue, then it does a lot of other printing, then it comes back to the yellow dot after a long travel to print the last circle. the long travel have ozed out some material whioch is now missing as you can see in pic 2. 5. I tried to show what i mean in CrossOver.png (pic 4) P.s how do you split a quote into several parts ? Best regards Asger

Hi Aag Just set the wall thickness to 8,5mm (34lines), which is just over the half of the nut size, this will give you a solid bolt. If you use something less e.g. 5mm then you will get some layers of infill right where the thread and the head meet, this happens even if you set top and bottom to 20 layers, probably a Cura bug. Good luck Best regards Asger

Hi I don't know if this is the right place for suggestions to improve Cura, if not please direct me to the right place. First some for the slicer: Fill massive walls with straight lines instead of 45 degree pattern Retract everywhere if the distance are over X mm even with infill and support Minimise travel by always start layer in the same corner as last layer ended. Minimise is way more important then finishing one kind of printing before starting another kind. Enhance strength in holes by letting second layer from top and bottom cross over the circles. File handling: Create local backup: save each gcode file to a local directory filename DateTime+Filename.gcode Post process plugin should be saved with project and be by project User interface: Post process plugin window should remember its size. Machine Settings window should remember its size. It should be possible to set the removable drive letter permanently and then dim the button when there is no disk. Ctrl+arrows should move the preview scrollbars When the horizontal preview scrollbar reach the ends there should be an automatic layer change and the scrollbar should jump to the other end and start over. Feed-rate colours should be the same on all prints, so that it is possible to know speed by looking at the color. Thanks for a great program Best regards Asger

Hi I'm sorry to say, but this, is in my opinion, no improvement at all and here are my reasons: The most important thing in the daily work are the model and the settings, which means that as much space as possible should be given to those two things. In the new version there is only half the space for the settings and the model area have also been smaller because of some huge header blocks at the top. Modern screens are usually much wider then they are high, which means as little space as possible should be wasted at the top and bottom. This is done much better in Cura 3.6 see pic: Cura 3.6.png vs. Cura 4.0.png The layer scrollbars are now positioned very far apart instead of close together as in the old version. The settings window is jumping all over the place, see pictures: Cura 4.0XrayView.png Sorry for this rather hard review of the new Cura UI and please note that it does in no way reflect my opinion of Cura 3.6 which I use daily with great appreciation. Best regards Asger
