Hello everyone , I recently bought a wanhao i3 plus , my first prints were actually amazing in terms of quality / time , but now i’m having this problem as you can see in the picture , on the right the filament is not laying on the bed and stays up until the nozzle come back and crash into it moving all the model… so what’s my problem ? (note: i am using the high quality standard settings of cura, i tried changing the settings still the same problem )

any help will be appreciated , thanks :slight_smile:

Looks like the nozzle is way too high. Is the first layer just extruding into the air? Is the model flush with the build platform in whatever slicer you are using? If it’s not software then I would check the end-stop on your z-axis. Might need to re-calibrate(not sure what method your printer uses).

yes it’s flush , this is just the raft, okay man i will try to calibrate it , thank you

Definitely looks like to big of a gap between nozzle and bed. What temps are you using?

You say this is happening on the right extruder. I assume then, that it is not happening on the left extruder. You also state that it ends up crashing into the print.

As such, it is my belief that your extruders are not both level with each other. Put a shim under the left extruder.

200 for nozzle 50 for bed

it’s only one nozzle … but i think yeah it’s leveling , anw thanks man !

i do not have or now that printer but

it looks like your first print layer is not sticking to the bed, can you check if you can get a piece of paper between the nipple and the bed when it is at 0,0,0 or first starts to print if so you need to reset end stops or bed level

I print PLA at 195 to 210 depending on which colour (they’re all different brands) and my bed temp is 60-70 depending on how much surface area. I also have a custom fan duct with a more powerful fan. I never use rafts.

If your bed is perfectly level, and your Y axis is also perfectly level, you might need to increase your bed temp slightly (maybe 60?) to help the filament stick. Bear in mind if your bed temp is too high it will probably make your bottom 1 or 2 layers stretch out wider than the ones above. This won’t affect you if you’re using a raft. If not, you raise your bed temp, but still try to keep it as low as possible while still being hot enough to stick.

You should test with a 20mm cube or cylinder until you find the right balance of temperature and then try your last failed print again.
