As long as you buy well documented electronics, you will not have any issues. You are just connecting boxes with wires, not much more complicated than wiring a stereo system, not like you need to solder components on boards. Do buy decent shielded wire, it will definitely prevent issues that you don’t want to track down. The steppers and Spindle will definitely need to be shielded, not necessary for the proximity sensors, but won’t hurt. Shielded wire designed for high flex applications is more expensive and a bit harder to find. That is one of the reasons for the higher cost of their prewired setups - they actually supply decent cables. .
I do urge you to learn at least a little about steppers. You will not want to buy most of the cheap sets of steppers and drivers that are out there. You want to look for some low inductance ones, the recommended driver voltage is related to the inductance by the formula V = 32 x sqrt(inductance). The ones that CNC Router Parts (Avid) sells are pretty good, but you may find equivalent elsewhere for less. Have you decided on whether you will go Nema23 or 34? I have the 23s from CRP on my DIY and am quite happy, I believe David used 34s.
I used the ESS, but if you want to go UCCNC, you will need one of their motion controllers. I bought an AXBB-E and UCCNC license a few months ago (for a planned smaller machine), combined they were less than either the ESS or Mach4. Based on Gerry’s recommendations, I think it is a smart way to go.
My machine is also 4’ x 5’, it is a great size, and easy to balance a full 4 x 8 sheet if you need to. In 3 years since I built mine, I have yet to need to, but am building a new house and shop and will extend mine (already have the extrusions) so I can do my kitchen cabinets. Don’t forget to assemble it allowing the spindle to overhang one end so you can do joinery cuts on vertical boards - consider 6’ rails.
I have a feeling that once you receive it, you won’t be waiting for winter to assemble. Have you started learning any of the software yet?
