I'm thinking in switch my old USB board by uc300eth.

I have see so good reviews about this board and I think is the way to go.

My problem is how to install the uc300eth to my configuration.*

Currently I got mach3 connected to stb 4100*

4 microstep drivers st-m5045 2phase 4.5A

4 23 nema stepper motor.*

Recently I purchased a spindle combo from Amazon.

110V CNC Spindle Motor Kit, RATTMMOTOR 2.2KW 80mm Water Cooled Spindle Motor ER20 400Hz 24000RMP+2.2KW VFD Spindle Motor Inverter+Mount Clamp+14pcs ER20 Collets+Water Pump+5M Pipe for CNC Machine https://www.amazon.com/dp/B0756WNP1J/ref=cm_sw_r_em_apa_fabc_QZ5Y501T8Z0CA9XB4KPE?_enco ding=UTF8&psc=1

The electric power is 110v.

I'm new on this and I will appreciate any guidance and a walk trwo in how to get this configuration and if i need to buy any other hardware in order to get my machine working.*

Also if anyone have think i should go in other direction besides uc300eth all comments will be appreciated.

Thak you
