I have an Ender 3 S1 Plus with a Textured PEI Plate. I am trying to print with PLA. And I am running Creality Print 5.1.7. I am printing the Flexi-Rex toy. The printer will start and after printing a narrow brim, it begins to print the object. But when the nozzle touches the brim, it will slide away and just drag on the surface. I have checked the distance between the nozzle and the surface. I have re-leveled the surface. When I start the print job, the bed temperature is set to 60C. I tried to increase that to 90C thinking it is not bonding to the surface well enough. I tried changing the filament specs in Creality, but they keep reverting to 190 for the nozzle temperature and 60 for the bed temperature. I have also washed the surface of the bed with hot soapy water. What do I have to do to get a good print?
I said ‘Brim’ when I think I should have said ‘Skirt.’
Needs more squish, adjust the z-offset while it is printing to adhere properly, you should be able to tune that in on the skirt, perhaps make the skirt 5 loops wide for extra time to tune. Also make sure that plate is properly cleaned with dishsoap and water, dried and wiped with IPA.
i had similar issues when i first got a 3d printer and found using one of the many first layer models that are available to tune my z axis offset was the best thing i did. it help me understand how the layers go together and how important those first few levels are. hope this helps
Thank you for your input. I did not wipe the surface with alcohol. I’ll try to tune down the nozzle .1 or .2 mm and see what happens. I though I already posted this. I did clean the surface and wiped it down with alcohol. I lowered the nozzle a little. The print started out OK, but it soon messed up when a small part was just scraped off the surface as it was being printed. I changed the temperature to 205 nozzle and 75 bed. Same result, almost to the step. I cleaned the nozzle and got the same result. Now I am going to just change the nozzle. I’ll see what happens then. I would still like any input from anyone.
Try doing the Z offset adjustments on a test piece or watch how the first layer goes down on your print… Use very small increments… Not sure if you can do it on your printer while it’s running which would be helpful.
Also I don’t think you need to run the build plate temp that high…
55°C - 60°C should be enough unless the temps are not calibrated too accurately…
The filament temp might also need to be bumped up to around 220°C or so…
