I have a ender 3 v3 se printer. I’ve only been able to print the sample one included with the sd card. Everytime I go to print it won’t stick to the pad. I’ve recalibrated. I’ve cleaned the nozzle, I’ve tried different bed and nozzle temps. I’ve reset the the z offset to paper thickness and cash register receipt thicknoess. I cleaned the bed with isopropyl and nothing will stick, It starts out but quickly lifts and gets caught up drags across the bed?? Any help will be appreciated.
Increase the bed temp on the slicer. i normally use 65°C for PLA.
Ill try it, I just tried hairspray and then a glue stick and it still slides around.
Be sure your Z offset is correct. I suggest manual adjustment. Don’t rely on the auto leveling function of the printer.
I had the same problem with you. I even bought a new build plate. But the problem was my Z offset, not the bed or the filament.
Make sure your file (g code) is correct. Sometime slicing software gets into errors. Try a different file.
Create a model of a flat plane of 2mm height straight on the build plate and see what will get printed.
Sometimes ± a couple of degrees on temperature can have a big impact on filament adhesion.
what is the ideal height for the z offset. I did it with a piece of paper and also a thinner cash register receipt? I just ordered a dryer, I’m willing to try anything
I turned up the bed temp and moved it to a different spot on the bed. Still balls up and drags
Have you tried cleaning the bed with hot water and dish soup? I cleaned it with that same stuff you have and i found out that hot water and soup with gloves on and scrub it lightly will do the treat. Because i had that same issue.
Have you tried a different roll of filament, just to rule that out? Textured or smooth plate? Glue should work when all else fails. Go find a bed level print file for that bed size. Start printing it and as its printing manually adjust the z offset to see if it makes a difference. Minor adjustments so you don’t mess up the plate.
There is no ideal height. Not all printers are assembled at the precise same dimensions.
From my experience, the correct Z offset is usually way lower than the one set at the auto leveling function.
When filament is deposit on the bed, it should spread like butter on bread. If the filament doesn’t touch the plate, then you need to bring the nozzle closer to the plate. That’s a negative Z offset value. And most of the times, it’s even lower than you think to get perfect results.
