Hello all. I am ready to purchase my first 3d printer and I know people gave a lot of praise for Bambu lab A1. Just need some help, what else do i need to purchase if I buy A1 3d printer. Should I just buy X1 instead knowing I want to use the 3d printer for business purpose? Your input is really needed.

My prints have suddenly stopped extruding midway through a print (Video shows printer going, but no extruder coming out) I thought this could be a clogging issue, but cleaning the nozzle didn't seem to help, so I replaced the nozzle entirely. While it was removed, I pushed the filament through and it seemed to come out without the nozzle just fine. Once I put the nozzle back in and pushed the filament through, it came out, but it did look like it was struggling to come out even though this was a new nozzle. Any idea how to troubleshoot this? It's the same nozzle size as the original, so I'm not sure why it would suddenly stop working I'm using this filament for my prints: https://www.amazon.com/dp/B0BM7446JH?ref=ppx_yo2ov_dt_b_product_details&th=1 But previous prints seem to have worked just fine with this filament
