I would consider myself to have a decent amount of 3D printing experience at this point, but I am struggling with this print. I am having issues with my first layer not adhering very well to my raft and then with the print warping later. I’ve probably tried to print this part at least 8 times with different settings and different results. I have also tried the usual fixes for these problems.
I am printing PLA on a Monoprice Maker Select 3D Printer and using Cura 2.3.1 for my settings. (I can’t get version 3 to work on my computer for some reason) Here are a few of the things I have tried for the first layer problem. I have the raft air gap currently set a 0.25. I have found I get very poor adhesion with 0.3 and at 0.2 I can’t separate the raft. I have tried the first layer print at different speeds. I have tried different fan settings. I felt that the fan was blowing the bead off but that was not the case. I tried unplugging the fan at the beginning of the print just to be sure.
As for the warping, I have tried different temps of both the bed and print temp. I use blue painting tape with a glue stick. When it warps, it usually pulls the raft with it. I have tried different variables of the cooling fan. Should I enable print cooling? I feel like this is only for objects that are printed vertically very fast. I was concerned that a draft in the room may be causing it be cause it is always the side closest to the wall that warps. I haven’t been able to confirm this though and I am trying to block any draft on that side of the print at this point. I have enlarged the raft and tried adding mouse ears but without success.
Thanks for any ideas.
