hi all, i have recalibrated my machine multiple times and i cant get it to have a nice print in about 3 months now. i also am having a hard time getting lubon to connect to the machine. does anyone have any tips? ---

You have to be more precise. Maybe share some photos of your print defects? Is your filament dry? This could highly affect the print quality. ---

Hi, my left nozzle seems to be working okay, its mainly my right. i tried to start printing this box and this is how the lines were starting, they were all over the place. i have ran every calibration the machine has. ![IMG_4562](https://us1.discourse-cdn.com/flex022/uploads/snapmaker/original/3X/2/d/2dae4cbf04f8b4fb2610bec7b473f17280beaf9c.jpeg) any advice would be much appreciated! ---

Your nozzle is too far away from the print bed. Try to decrease your live t offset of the specific nozzle on the touchscreen while printing. ---

is there any way to get this to like re-calibrate so i dont have to adjust each time and watch it? this is the other issue its doing, the print is not smoother at all its all over the place ![IMG_4564](https://us1.discourse-cdn.com/flex022/uploads/snapmaker/original/3X/f/5/f57956eb25a2cefbc8f30a9d7add79fc1ba893ed.jpeg) i appreciate your input! ---

The z-offset is saved till the next leveling. Your model surface looks like wet filament or bad bonding. What material is it and what temperature was your print? May try another spool? ---

it was a brand new spool of white snapmaker PLA. maybe it was a bad batch? all the print settings for the heat are what the system defaults, i’ve never changed them. should i try and level again and then do the z-offset calibration? its just odd that the left nozzle prints pretty clean and then the right is all messed up like that ---

Does the same filament print well on the left nozzle? You could simply adjust the live z offset for only the right nozzle while printing, there is nothing to worry about. ---

yes the left does seem to print fine on the left. okay i will try that and report back. thank you. ---

I adjusted it down right as it begain to print and it was still all over the place its like it pushes down in some areas like it should and then lifts up. i even replaced the heated bed thinking the bed could be warped. ![IMG_4565](https://us1.discourse-cdn.com/flex022/uploads/snapmaker/original/3X/b/a/ba704bd03c586603f0b46e7921daa25e39811685.jpeg) ---

Here is the same filiment on the left nozzle, all clean. i dont understand why the right is so messed up. ![IMG_4566](https://us1.discourse-cdn.com/flex022/uploads/snapmaker/original/3X/c/c/cc7514b8c037a8062d6ad22a5adb00f4b9b192b5.jpeg) ---

Check your filament path. I think your nozzle is pulled back because of counterforce of the filament path. Maybe try a single piece of filament without feeding tubes or any other guide and print a first layer. ---

This is how my left side turned out. how do i check the filament path? i think i may try and hook up the original 3D module and see how it does. do you have any suggestions? i appreciate all your insight. ![IMG_4567](https://us1.discourse-cdn.com/flex022/uploads/snapmaker/original/3X/b/3/b38b073de23cecb733cc37b8bff7e81f0d3bcbbd.jpeg) ---

If you see your nozzle slightly rise and fall while extruding/retracting, there is too much counterforce for the raising mechanism of the dual extruder. Where is your spool positioned? Do you use the original holders and tubes? A simple workaround would be to put the spools into the enclosure or, like I wrote before, to cut a piece of filament to see if the first layer of the right extruder simply prints. Observing the print by sitting near and looking at the behaviour could solve it fast. ---

I have the filament sitting in one of those boxes that warms the filament. I have it sitting on top of the enclosure. I tried a print on the original 3D printing module, and I got the same result. I will try a print without having them in the box and put it back on the original spool holder. It’s odd, though, because I’ve printed a ton with the box, and it suddenly started doing this. ![IMG_4569](https://us1.discourse-cdn.com/flex022/uploads/snapmaker/original/3X/c/1/c1dac7472110daf03b1ab2335c6e1439ff41e023.jpeg) ---

> [@Zmoholt](#): > > I’ve printed a ton with the box, and it suddenly started doing this. > [@Zmoholt](#): > > cant get it to have a nice print in about 3 months now Wondering about the contrast of your statements. The last picture seems wet filament to me but let’s see how your next prints look like. Unfortunately you have more than one problem here.. ---

attempted to print chain links, and here we are again. I’m using the original printing module now. I wonder if I need to do a factory reset? Could my machine have a bug? ![IMG_4660](https://us1.discourse-cdn.com/flex022/uploads/snapmaker/original/3X/1/1/110286d7a0b203a404687064242c587d33336e7f.jpeg) ---

Okay, we are mixing more than one issue in this topic.. What happens if you print only one of these links? I think you print pla (are you?) and it is printed too hot (bed and or nozzle). Maybe it could help to improve if you let the enclosure open. Additionally maybe your retraction settings are not on point. Let’s do one step after another. ---

Can you confirm you are using the dual nozzle head? [Next page](https://forum.snapmaker.com/t/a350-with-duel-extrusion-head-will-not-print/43484.md?page=2)
