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.
This is probably a well over-engineered design. The feel of the lever and its operation is very positive to ensure you do not select the wrong setting. There are detents in both the Flap selection decal as well as the case, providing a level of feel, unlike other units I have tested. The lever also features a side sprung loading. A mini servo is used for flap trim indication.
