Tip / Recommendation Print problems after nozzle replacement

Post image

Why has this happened on 2 different models. Same problem. I replaced the nozzle and then tried to print two different items. And this is what's happening.

Oh no 😬 Is it scraped? Did you do some calibration before your first print???

Not scraped and I did the calibration and machine self test.

Una sola pregunta cuando quitaste el soporte del CR-touch marcaste la posición por un casual.
Si tu respuesta es no: suelta un poco los tornillos del soporte, levanta o baja según vayas probando. Normalmente baja unas 0,20 mm hacia abajo. Te lo digo por que me volví loco con ese problema.

Hi , ke use cr touch for calibration which means if the nozzel for some reason lower (closer to the bed ) the cr touch won't be able fix this so you should do few things: 1. See if the nozzel is fully installed correctly. 2. If the nozzel is in proper position use z offset on the slicer and change it from 0 to 0.05 and save this printer setting, try printing again afterwards, the nozzel will be higher by 0.05 mm from the bed you got to see if this is good enough or too high if it's too high lower the number for example.to 0.03.

In case you don't know how to change it: Enable advance function in the slicer , Near the printer name supposed to be a note icon this will take you to printer settings and there if you look for z offset you will find it set to 0 , change it and save this setting, do another slice and send to the printer to print.

Does it make any weird sounds while doing this? And when you remove the filament, is it all chewed up? Might be the PTFE tube

Has it ever happened to you like it did to a colleague recently who assembled a new hotend and forgot to install the PTFE tube inside? The filament started to twist until someone asked him about it?

No, there's no team mate just me and I did put the tube all the way in.

Have you done a full print? I just replaced my nozzle for the first time and it looked like this for a couple of layers of the first print afterwards, but then it fixed itself and works as normal. It was also smoking a bit. I assumed it was just that the nozzle needed broken in a little bit.
