I'll have to double check but I think the extrusion slows like that right before the confirm option pops up. I will check to make sure the print core is clean and not clogged. I don't think it is though because it extrudes just fine when it first starts. I will do some hot/cold pulls as you suggested as described on the UM website though. The feeder is clean. The marker is in the middle position. During the load, I heard some clicking the other day. Since then, I removed the cover over the feeder to make sure nothing was in there. I will try swapping the print cores between 1 & 2 to see if that helps. I thought the feeder was fine though because it seems to pull it in/out to load/unload just fine. Thanks for your suggestions. I'll try them tomorrow when I'm back around the printer.

I loaded a new filament and the filament comes out normal for a while. It slows down a lot or even quits after a few seconds in which maybe 7.5-10 cm has came out. I clicked confirm because I thought that's what it was supposed to do, but now it does not print. When I start my print, this is what I get. It should be a continuous line but it puts out little bits or something. I even tried slowing the print speed down to 50% but it did not help at all. Does someone know what i need to do to fix this?

I haven't tried a small object alone but that may be something to try. Just try placing a small block in the 4 corners. The back right corner seems to be fine thought because it did start to print as it should. I've attached my file here. Thanks for the help with that. UMS5_ComponentHolder_s1.3mf

Yes, I know that it could throw off active leveling. That's exactly what happened until I fixed it doing a manual calibration. After the manual calibration, active leveling works. The link you just posted is exactly what I did, and it then started passing the active leveling. That is exactly why I'm confused and posting about this. If it passes active leveling before the print job, it MUST know where the build plate is. That's the whole point in active leveling, right? So I'm not understanding how/why during the print process it would go back to the area where it touched the glass to calibrate itself and but start printing about 1 cm above the glass (even thought it knows exactly where the glass is).

Ok thanks, I can try this later when I go back to my printer. It seems like the menus are similar between the S3 and S5 but I should've mentioned this is the S5. I should add that when I first tried my print, I get a message that it could not complete active leveling. I did a self calibration by adjusting the 3 knobs and using a sheet of paper to feel for when I felt enough friction to slightly grab the paper (it still moved relatively freely). I tried my print again and it went through the active leveling where it touches the glass with no problem. Are there any other suggestions? I don't know anything about 3D printers but I have a feeling this will not be the issue since it passes the active leveling test. I will definitely try though.

Hi, I am brand new to 3D printing so this may be a simple fix but I haven't figured it out yet. Basically, when I go to print my design it passed the self leveling process where it touches the nozzle to the glass in all corners of the hot bed; I'm assuming it's calibrating itself so it knows exactly where the hotbed is. When it starts to actually print, it starts in the back right corner. Everything is fine and it builds up between 0.5-1 cm. It moves toward the front and instead of printing on the glass, it is about 0.5-1 cm above the glass. it's needless to say, that doesn't work. I've attached an image of what it should look like and the mess that I actually get. Any help with this is greatly appreciated. I'm using ABS and breakaway.
