OK so I'm going to order a new 600 x 600 x 300 cabinet and parts for my electrical panel, can someone check to see if I need anything else...if I've missed something:

600 x 600 x 300 - 1 off
20A door isolator (presume NC contacts so contact is broken when door's opened?) - 1 off
Emergency stop panel mount button with NC contacts - 1 off
Green push button panel mount, NO contacts - 1 off
Red push button panel mount, NC contacts - 1 off
Green LED panel mount light - 1 off
Top hat slotted DIN rail - 2m length
2.5mm grey DIN terminals (gettting 50 off)
2.5mm Earth terminals (getting 25)
bootlace ferrules 0.75mm, 1mm, 1.5mm (100 of each)
Crimping tool - 1 off
25x40 slotted cable trunking - 2m

I've got 2 x 120mm 24V cooling fans which I'll get filters for which I'll mount on the sides
I've got 1.5mm^2 4 core shielded cable (about 25m) for connecting the steppers to the drivers
Was thinking of getting 3 core 0.75mm^2 shielded for the limit switches, is this the correct cable to get?
What other cable will I need?

I'll be ordering parts for my PSU, so far looking atthe below components. Can someone please comment on them please to make sure I'm going in the right direction?

Calcs:
Toroidal voltage V(DC)=1.4xV(AC), so 70/1.4=50V
Question, I've read that if yout supply is greater than 230V then the voltage output is higher which would be a bit too near the max 80V the AM882's can take if there's back EMF from the steppers on deceleration? So would it be better to get a 2x24V transformer as linked below?

Current: I've 3x4.2A steppers (Z axis, Y axis and a future 4th axix) plus a 6A Nema34 making 18.6A but 60% is 11.16 so call it 12A? So transformer needs to be 12Ax50V=600VA sdo nearest is 625VA.

Capacitors: C(uF)= 100000xCurrent/Voltage = 17,143 so a 22,000uF 100V capacitor should do....any ideas where to get an economical one or are multiple smaller ones better?

Bleed resistor, I'm either going to use one switched through a relay or is it not worth bothering with? I'm more inclined to use one as I'd rather discharge safely than just leave the steppers to drain the caps. My calcs are: R=5000000/2200=227Ohm, rated at V^2/(2xR)=10.8 Watts. Any suggestions on what to get here?

I'm sure there's more that I've forgotten but I'm sure that someone will suggest it (hope so...)
