Since 2020 with an Anycubic i3 Mega S and tinkered. For quality, I bought an A1 mini and after three months switched to an X1C. I also successfully built a Voron 0.2 myself and have since tinkered with a Prusa MK3s clone. Own an Ottoeject/Ottomat3d automation for the Bambulab X1C, had software developed and am developing it further myself
