No, you didn't waste your money, as UCCNC is superior to Mach3. Although your throwing away the $200 cost of the ESS, but you should be able to sell it for $125-$150.2. Is it possible to replace the Smoothstepper in the CNCrouterparts enclosure with the UC400ETH and, if so, how? does anyone have an XML file? Did I, in my naivety, waste some money on a UC400ETH and UCCNC license?
Can you post some pictures of your cabinet, specifically of the smoothstepper and breakout board? It may be as simple as plugging the UC400ETH into the breakout board. But you may need a new breakout board or two, if the one you have uses pins 2-9 as inputs for one of the ports, as the UC400ETH does not support that.
16 I think?3. What gauge wire from VFD to 2.2 KW spindle?
The best way to do that is jog up against hard stops, and press the Ref All button. You need to home the machine in same place every time.4. How do/can i set machine absolute coordinates and prevent machine from leaving that area without homing switches?
After that, you can use Softlimits. But Softlimits require a repeatable home position.
