One of my two Creality Hi printers has been failing all week. The prints won’t stick to the bed at all.
The first thing I tried was printing a calibration cube, but it failed. Then I cleaned the build plate with soap and water, and tried again — still didn’t work.
I’ve read that it might be a Z-offset issue, but I can’t seem to find a way to adjust it manually on the Creality Hi or through the printer settings.
After that, I ran a first layer test (image attached in the post), and nothing looked obviously wrong or extreme, so I went ahead and tried another cube… and it failed again.
At this point I’m not sure what I’m missing. Any ideas what else could be causing this?
There does not seem to be anything wrong with your bed levelling, is this PLA?
Does it always fail at the same height? Maybe you Z axis cannot move higher and it bumping the print from the build plate?
Since the first layer looks good, I suspect less zoffset and more a settings issue. What material are you printing and what bed temps? For PLA, I do 65 bed temp.
You can adjust zoffset during a print in the expert mode menu on the printer, but I doubt that is the issue.
Have you tried glue? Basic kids purple stick glue. Sometimes you need to use it. It might not be ideal but its worth a try. Also try changing the infill, that looks like grid, which will actually hit the previous layer so that can knock the model off as well.
As far as changing the z offset, it should be under settings, expert mode on the printer. It can also be adjusted in the printer settings in the slicer but I wouldn’t worry about that yet. Do another bed print and play with the z offset while its printing to see what happens.
how much should I add to see if that is the problem? i mean like 0.05? 0.025?, something else That I notice is that the first layer actually sticks well to the bed, but as the print continues, the part starts to warp. The corners lift up and the print gradually detaches from the bed during the following layers.
This happens even when printing a simple cube in the center of the bed.
Could this be related to cooling, bed temperature, or another issue causing warping?
no really, but i ve use the same spool on both of my creality hi printers and only on this one theres a problem, but Ill try use another spool to see is it is the problem
Right now I used brim for another test cube print and its looking good, no detachments from the bed, was that the problem? not using brim, I also set fan 0% in the first 5 layers
left to right, the bad one didnt use brim I see some warping. middle one, 65ºC bed temp, 230ºC nozzle temp, brim, 0% fan on the fisrt 5 layers, last one printed in my other creality hi Printer with no brim
65 degrees is too hot for PLA. That could be your issue. Should be around 50 for a regular build plate. 230 is also high. 200-220 typically. I would leave the fan settings to factory. No need to overthink PLA.
For me, using local manufactured PLA I need 65 and sometimes 70°C on my Epoxy resin bed to have a good adhesion, the manufactured recommends at least 65°C due their formula.
so no, is not too high, it deppends of the bed and the filament.
The reason it keeps falling over is that I had issues with the same got a textured PTI sheet for my machine haven’t had an issue since I think it’s the print but itself because it seems that the stickiness is very inconsistent
