EXACTLY my situation. Had an ender 3 pro, modded that thing a lot, bought an A1 with AMS. Now i can’t even imagine going back to the ender.
I think the AMS is the only reason I’d go with an A1 - my modded V3 SE is a dream in its current iteration. Happily printing PETG / TPU currently with a spool of ABS-GF waiting for an enclosure to be finished.
The AMS is amazing. I just bought my 3rd and 4th when they had their black friday sale. Multicolor prints look soooo good and it’s very reliable, unlike the MMU2 I had on my Prusa. Pretty soon I’m going to attempt to print some wheels (maybe ABS or PLA-CF) with some squishy TPU tires.
