So on Tom’s YouTube he seemed to suggest aluminium plate was better for a heat bed. So if that’s the best then what type as there’s lots of grades of aluminum and where to buy from? I’ve seen some on AliExpress but I question how flat the actually are and the tolerances. Or is there a better option? I’ve seen some mk42 clone beds on there but not sure how good those would be.
Check out these beds at the link below. Top notch quality and super flat aluminum. If the 2 stock sizes don’t fit your needs and you want a custom size just send a DXF file to @Heath_Harper and he will give you a quote for it. Great customer service.
For the stock bed sizes there are also very efficient fast heating PCB heaters on the site.
