Thanks Isaac
What are you using for a controller ?
As for cooling .. I thought a couple of freezer ice packs a day in the bucket will do for a bit.
I just bought some honeycomb for the bed.. I bought from here ..
9.1mm (3/4) 3000 Alloy Aluminium Honeycomb to Buy Online - Easy Composites
as it was a lot cheaper than buying from the people selling it for laser beds ! .. I should get 4 beds out of this piece :)
