I have bought my first roll of PETG for my i3 mega. My issue is the initial layer not sticking. So I cannot find the correct temperature for best printing.
I have read one article from rigidink ( https://rigid.ink/blogs/news/175700615-petg-filament-heres-what-you-need-to-know ) that mentions increasing the z height. But I have not seen this meantioned anywhere else. The brand I have( https://3dprintz.co.uk/collections/petg/products/petg-1-75mm-filament-black )says the printing range is 210°C - 230°C (I have tried 210°C, 215°C and 230°C) and a bed temp of 70°C - 80°C which again I have tried. I have also tried with and without cooling and also no cooling on initial layer.
I have created my first item on fusion 360 and managed to print a prototype in PLA (it is half a compression fitting for a friends dress making mannequin which had broken.) I now want to make a stronger version.
