I am make a DIY 3D printer. And I need to which stepper motor I should use. So, I am planning on making a 18x18x18 or 20x20x20 max print size. I am only having a single z-axis like the prusa mini. Which stepper motor should I use for my z-axis, x-axis, Y-axis and the extruder (Planning on using 1.75 mm filament). How do I calculate the power needed? Will 2.8kg or something near be enough? I am not really good at stepper motors, so sorry for the lack of knowledge.
I am not sure if I am following the rules by asking this question. Sorry
Thanks for reading
