    Thanks you. After some tests, trials and errors, I can now print whit the accuracy I need ! The settings I use are the one above with jerks at 20, retraction at every layers. I use the engineer profile at 1.5. Now my prints don't expand. The settings that help is Horizontal Expansion : -0.16 (For Ultimaker PLA Tough and Ultimaker PLA) Hope it help others as well. I got scared for a while, but the problem was the guy in front of the printer not the machine.

    🙂 - let's better say it was a mix of a lot of options in Cura with difficult requirements. Thanks for the feedback, and happy that it is now working for you!

    @Arnookie I wouldn't have thought to install 4.6.1 without your post. Thank you. I had the same move-to-4.7.0 experience but assumed it was that my object was too small or that I had fouled my extruder. Installing 4.6.1 gave me a much cleaner result. Thank you.

    The sensors would need to be present and the firmware would need to be able to translate each sensor and likely be sophisticated enough to make a decision about what to do. The printer would need to be networked and have an address book of destinations to send the notification to, as well as internet access or a phone line of some sort. The destination hardware and software would need to be constantly monitoring for messages from the printer. Once the printer decided that a particular malfunction at a sensor (let's say the "spaghetti sensor") needed to go out, it could send a text message to the users' phone where a special tone would notify the user of a problem. If this was to occur at 3am then the user's significant other would punch the user in the side of the head and say something constructive like "WHAT THE %#$@ IS WRONG WITH YOU. SHUT THAT %@%# THING OFF" At that point the user would go to the printer, look at the problem, and say to him/herself "Yep, that ain't right." and then shut it off till morning when the problem could be dealt with. The technology is certainly available for all of that. (I myself have designed a spaghetti detector that would work.) Unfortunately, it's probable that none of it could be installed as an upgrade to an existing printer, and that on top of the additional $6k cost of a new printer would be another $2k for the privilege of getting whacked in the side of the head in the middle of the night.

    I agree with that. In my company we track the usage of filament per Person and Project. If you forget to write it down straight after slicing it's often more complicated then it should be to figure out how much filament you used for these models

    Did you re-slice the model and try to print the new Gcode file - or did you run the previous Gcode that worked? Within the printer under Control / Filament make sure "E in mm³" is "Off". Looking at W1_underextrude.gcode in line 4 it says it uses 20.868m of filament. Dumping the file into AutoCad I come up with 505720.78mm of extrusion and a total E of 20.89mm. So that's whats going on in the Gcode file. With an initial layer height of .2, a layer height of .25, and a line width of .4 and doing some math (sorry grNadpa) then layer 1 is 16020.78mm extrusion and 534.5mm of filament. The rest of the file comes to 489650.5mm extrusion and 20357.30mm filament. Total filament on a piece of paper comes to 20.891meters of filament. That is a difference of .0238mm of filament which equates to about .5mm of extrusion out of 505720mm total extrusion. I would say that in the case of the W1_underextrude file that the problem is not in the Gcode. I did notice that in line 24 of the gcode file there is M92 E94.8. That number does represent your extruder E-steps right? Sincerely, Dr. Bunsen Honeydew Muppet Labs PS I printer about 10 layers and they looked good.

    There's a couple of things to check to start--during the active leveling process is your second Print Core moving up and down with the lift switch as it should? If it doesn't you will get an active leveling error. The other thing is to check your manual leveling--if the build plate is too high it will error out as well. You want the heated metal plate to be about level with the center lip on the base plate; I have photos and a video here.

    I generally respond to those pings, although I don't track issues on the forum itself. If you seek to modify the layer heights, look for the buildLayersWithHeight function of the Slicer class: https://github.com/Ultimaker/CuraEngine/blob/51ee4b7adf6dfd112241cdf3fd5681e87cf6370c/src/slicer.cpp#L929 In this function it determines the Z coordinate of each layer, either by calculating from the layer height and initial layer height, or by asking the AdaptiveLayer class.

    /facepalm Thank you good sir, I was certain there had to be an option for it somewhere, but for the life of me i couldn't find it yesterday lol. Was already doing the manual rename, but forget every now and then. Interesting to know, thank you again. Cheers Nallath, I went and found a plugin by fieldOfView (aka ahoeben on forum ?) called "Custom Printjob Naming" that works precisely as advertised.

    Open %APPDATA%\cura\4.7\cura.cfg in a texteditor (eg notepad). In the [general] section, remove the lines starting with window_left and window_right Save the file and try starting Cura again. If that worked, go into the General preferences and uncheck the option to "Restore window position on start".

    Can you clarify what you mean about calibrating the printhead? Are you looking to check the alignment of your axles and check for play? I've got a guide here. Bowden tube and couplers are the top things I usually replace. With that much runtime on the belts though, you may want to replace those as well. I usually find they need it between about 3k and 4k print hours depending on the printing environment. I've got a guide for that here. If you're seeing a lot of black dust building up on top of your XY motors or the belts have gotten noisy, it's time to replace them.
