THIS TIME I ALMOST WENT TOO FAR (Patreon)

Hi everyone!
This one has been in the oven for a very loooong time, and it is finally time to bring it to life. This one is new 3D printer is going to be huge! The planned print volume is 1000x1000x1420.
It is going to have a moving gantry on top and the bed will go up and down. I'm still debating myself about wether to go the HBOT or the CoreXY way but I find hard to justify the advantages of the nimbleness of the CoreXY configuration in such a huge printer. The gantry is planned to be (for now) a 25x50mm alu profile with an HGR20 linear guide and a single block which is going to be quite heavy anyway. I could swap the aluminium profile for a carbon fibre one and the HGR20 for a MGN12 and try to make it lighter so CoreXY is justified... Any feedback will be appreciated.
I'm already thinking about using beefier all threads for the connections and I may even attempt to TIG weld the frame once everything is up and running. Also I will add cross members to stiffen it once I know what I need to clear, included those 3D printed braces at the top.
In the next video already in the making I'll build and setup the bed assembly for which I'm already having issues as the heating elements all add up to 5.2 Kw. I have no single socket in the shop that can supply that, so I'll have to either use diodes to divide the four 1.3 Kw heating pads into alternating phases of the mains power or try and setup one of the three phase sockets to feed different phases to the different pads (seems a bit overkill).
Even though what I make in this video looks a bit simple, every step in this project seems to trigger a few other challenges and that's why I'm separating it into a few (three?) videos so I can go deeper and make it right.
As always eager to read your feedback! Thanks!!!
