Hi Roadrunner,

Nice looking build you have going on there.
I am almost in the same level of components (electrical wise)
1 x CP0-10V BOB
4 x Nema 23 4Nm steppers
4 x CW5045 Drivers
2 x 36V PSU
1 x UC300 motion controller
1 x 24V PSU (Safety circuit)
1 x 5V PSU (BOB etc)

Did you by chance purchase through CNC4YOU?

I also have the same issues with CAD, I am a mech engineer and pencil and paper are what I know, but I guess we both need to brush up on CAD.
I am looking at FreeCAD its looking good so far.

Will enjoy watching your build as it might be in tandem with my own build.
ATB,
Ian
