I run mainly Prusa printers, along with a home-brew high temp unit I'm currently building up. I have an MK3s, Mini, and then a large format resin printer I use regularly. I also have a 5 head XL on pre-order (since announcement day). I make a lot of jigs, manufacturing helpers, custom adapters/feeders, etc. Stuff like that, plus whatever else I may need (mounting brackets for various everything is common). I use ESD PLA for stuff that micros touch.
The MK3s is getting a bit long in the tooth for the UI, but it works, doesn't glitch, and just makes prints w/o complaint or problems or tinkering. The Mini works just fine as well, I keep a .4mm nozzle on it for more detailed prints (.6 on the MK3s). I upgraded both with the Super PINDA sensor, and use the Satin bed sheets.
The satin bed sheets are a game changer.
The slicer upgrades and improvements are game changers.
The Super PINDA helps a ton when changing bed temps from different filaments all the time (more constant first layer offset).
I can't wait to get my XL.
The Bambu looks interesting, but all the hardware is proprietary and the company is a startup. Also, to get full utilization from the machine, you need to use their slicer (and IIRC was cloud?), but basic prints can be done from any slicer apparently, so you have to hope they make a good slicer and keep it up to date. I'm not sold on them yet, we shall see. If that company goes under, or they simply decide to stop parts production, your machine will lose all support.
