Hi Robin, yep screwfix conduit was the cheapest by far. Had to chop a few rough patches off and take from the ends (as they had stored it on something which left an obvious fulcrum point and slight bend) but it runs smooth.
The bolts I just made do with what I had or bought what I could from China.
My boxes will be on the bit of the table to one side of the CNC that I’ve left clear, I’ll build a box with a fan and a filter to stop it getting gummed up.
Well done on getting the crown drawn, I think I’m going to find the electronics side of it a lot more difficult than the construction side
