I have had the same idea cca 3 months ago. I had updated from Anet A8 - OK it was not Anet any more, I have changed guide rods, bearings, vertical part was a Prusa clone etc. I had used glass on the bed for printing and Ikea Lack as enclosure. Let's say, it had worked.
I had chose to go with better printer. My candidates were:
- Prusa MK4 - build volume 250 x 210 x 220 mm
- Creality K1 Max - build volume 300mm^3
- Bambu Lab P1S - build volume 254mm^3
On the beginning I wanted to buy Prusa, but quickly changed my mind. Enclosure is necessary (I can use my old from Anet), which is quite big due to the bed slinger design. XY printers are smaller and have bigger build volumes, chosen ones comes already in enclosure. At the end I chose P1S with AMS and I have not found any issues with it (K1 does not have possibility of automatic material change). I almost do not use PLA. Mostly I print from PETG or in special cases from ABS.
My remarks:
- Compared to Anet the printing is fast and the printer is compact (needed footprint is cca 40x40cm), AMS I have on top
- I user Orca Slicer
- I do not use the AMS for colorful printing - I use it for filament storage and to ad color in one or two layers. Yes it produces a lot of poo if one wants to print in color.
- I use Ikea 365+ box for external feeding of filament that does not fit to AMS
- bigger spools need to be rewind to smaller one, AMS Hydra can be printed or external filament input can be used (I have printed Y splitter to make the job easier
- I do calibration of new filament spools + I do additional the temperature tower calibration
- I use 0.4mm nozzle and print in normal mode - for me it is fast enough and I have no reason to use 0.6mm nozzle like on Anet
