Hello guys, I am having some trouble getting my Kossel Pro to run at an even mildly acceptable print quality, there are huge gaps between infill and the outer layers and the outer layers seem to be stacked awkwardly without any level of precision. I think this is because it is now feeding correctly until it gets to the third or fourth layer and when it gets there it assumes there are layers below it, which there aren't, and continues to place into the air causing the bad quality. I work in a machine shop and need these prints to look nice and work well. How can I improve print quality? I have tried various differing start heights from .2mm up to 2.5mm and found little to no improvement in the final product. I also made sure that the calibration rod is tight and firmly in place, it was. I have now spent about six hours balancing these factors and running tests with little to no improvement. Again, what do you suggest?
