    Hey ? The printer has 1200hours, in 3years ! I'm not a big user I guess ? The narrow end was aliitle rough, so I trimed it a little ( not very good at it ^^ ) filament could pass smoothly and still can... But it's allitle tiny bit ovale ! Should I change it ?

    UM3ext can't start a print....

    Hello, the active leveling was off because i couldn't manage to start a print with it, error each time ! even if I leveled the build plate manually ? After searching on the forum for similar issues, most of the people trying to repair this mess breaks the printcores, if not the entire thing ! I'm contacting my local resselerfor support this afternoon ? Thanks !

    underextrusion multiple models ?

    Hello, I never actually changed my TFM coupler, but after checking, there are no apparent damages on it, no burns or anything... Should I change it anyways ?

    what temperatur , I'mkindascared to melt the plastic because nylon is 255°C, one of the highest temp, or maybe they usespecial heat resistant plastic... If someone knows ?

    UM3ext can't start a print....

    Hey ? The 5 things were the same (um3EXT, AA0.4 with pla, BB0.4 with PVA) After struggling, I manage toupdate the printer wia USB, the wifi wasn't working anymore --' So it's all good on the bug part, but because myprinter lovesproblem, the bed screws (the ones you turn to calibrate height) decided to take vacation and just pop off, resulting in bad things going on in the extruder, see in the photos, the whole thing is filled in Nylon !! ! This is when i regret the metal of the UM2, it happened to me one time, just get the heat gun, kinda messy, but cleams up ! on the UM3, because it's plastic, can't do anything, so if you have a tip ! Thanks !
  10. Hello, So, I have my UM3ext since 3 months now and it worked just fine until the past 1weeks, each time I try to print, it tells me : "this printjob is not suitable for this printer" I need to press ignore about 6 or 7 times so that the message dissapears. then it will say the print is to big for the printer. After, it starts preparing for the print, sometime, it will say heating the bed, and when I look at the target temp, it' 0, so it will just stay like this forever. Some other times, it try to do the active leveling, and the printbed goes up and down for 2mins until it says ER22 or ER26 ! I'm printing with the same settings and same filament than usual, I tried printing an old Gcode that worked before the problems started, doesn't work ! I have tried to : remove and add the UM3ext printer profil in Cura, change the settings, all kinds of 3D models, a different slicer(S3D), resetting the printer, leveling the printer bed, reinstalling cura, the 5 last version of cura, slice it on another computer, differents USB keys and other things that i can't remember right now ^^ If anyone has a clue of what my printer is doing, I'll take it :3 Thanks !

    Flow Rate cura 3.3.1 UM2 hidden

    But I don't have the sweet little timer that tells me how long to wait if I change it... What a dilema ! ! ! I'll see on the go I guess ! Also, did you just make a reference to spider man or is it me ? reference :3

    Flow Rate cura 3.3.1 UM2 hidden

    Oh ! So I need to change the flow rate every single time I guess ? They should update the Gcode flavor na ? Thx for quick reply :3
  15. hello, i'm calibrating my UM2+ext and I'dd like to acces the flow rate in Cura, but it's simply not here, when I check in the options I have put in my taskbar, there is a "!" next to flow and it says : "This setting has been hidden by the value of the G-Code Flavour. Change the value of that setting to make it visible." I don't have this problem chen I change Gcode flavour to marlin or when I use another printer ! it has to do with theUltimaker2 Gcode Flavour, but why ? makes no sens to not access the flow ( or extrusion multiplier, call it has you wish ? ) Anybody has a clue on what's going on ? Merci Beaucoup ?
