The ultimate printer I can recommend is the Bambu Labs X1 carbon with AMS or P1P if you have deep pockets. ($1200). It's a massive leap forward in 3D printing, with excellent quality and impressive speeds. It's pretty much press print and go as the software and hardware do the calibration before each print.
