"Origami" CNC Plasma Build - folding 1200 x 600mm cut area

Rod - THANK YOU!   I'm a bit shite at the physic's stuff.  And invariably get myself turned around and bent in half trying to work it out. Then look at the numbers and never quite trust them.

So with the independent review I will barrel on as planned.   Only bunner is wont be in town until next weekend.  But means I can plan out all my machining steps.  Might do one last tweek to how the nema23 is mounted.  It would ideally have a 6mm offset to the left so way more of the pully is fully engaged on the motor shaft.  So a bolted overlapped plate will do that. Or I just try the existing design on that part and see how it goes.  Can always remake/adjust it.

HGR/HGH/HGW combo at 15mm will handle that easily but MGN15 will not be comfy.

Aren't the MGM style the low profile/thin ones that I seem to recall seeing on some 3D printers?

MGN, yes those are the ones, luckily/unfortunately i will have to buy some skinny ones, MGN12 to retrofit one of my printers and i will need at least 3 of them - preferably 7 but there are only 4 in stock locally at 50 euro a piece so that made up my mind = 4 it is !
Since i do have HGH25 i might end up using 3 MGN12 for the X and Y and use 2 HGH25 for Z, should be enough to hold about 2KG without wobbling ! Poor Ender 5 Plus...

Tommy, before setting your plan, have a look at rail lengths on P 85.
Using MGN may result in a very small plasma table!

It will be small for sure, the length of the MGN12 rails is 400mm !
But it is not plasma, so for a 3D printer with 350x350mm bed makes it a big one, although i have even bigger at 450x450x470mm, 3 of them !
