So yesterday I tried my first print which went ok but I know these machines can produce a lot better quality. So after making the adjustments that I mentioned yesterday ( raising the hot end slightly more and setting infill to 100%.
This worked really well, or so I thought! I watched the first few layers which were perfect and left it for 20 minutes or so and came back when it had finished. I found that one of the corners had lifted up of the surface of the bed probably about half way through. After a bit of research I found out that ABS is susceptible to bad warping which means the corners of prints don't stick down to the bed too well and so they curl up away from the bed.
This picture shows the layers curling up at the corner.
There are several solutions to this problem that might work:
- clean the bed to get rid of any residue especially oil or finger marks
- make sure the bed is hot enough ( around 100 degrees C for ABS) to make sure the first layer sticks to the bed properly
- make sure the bed is level, if not one corner/ side could be lower than the others so the filament doesn't stick to the bed as well as the other corners.
I think that my problem was that the bed wasn't level as like I said in the previous post I hadn't done any calibration on my printer.
