If you are using shielded wire between the motor and driver, the shielded portion (the reflective jacket within the insulated portion of the wire) and any spare wires, or stranded wire should all be grounded and be inserted into the GND terminal on the driver.

When using shielded wire from driver to stepper motor, where should I connect the shielding? Should it be ground on transformer or something/somewhere else?

All you need is a CNC controller like the following options:

https://www.buildyourcnc.com/item/electronicsAndMotors-electronic-component-breakout-Mach3-USB-Board

This controller is easy to connect using standard wire screw terminals and works with the mach3 control software.

https://www.buildyourcnc.com/item/electronicsAndMotors-electronic-component-breakout-Mach4-mach3-USB-ethernet-Board

This controller is a little bit more difficult to connect, but is a more feature-rich controller and will work with both mach3 and mach4 CNC control software titles.

Specifically, a CNC controller connects to the computer via a USB cable and connects to the motor drivers. These controllers also connect to the limit switches, spindle/router control, air/fluid/mist control, etc.

You will probably have post processors like the following listed:
Mach2/3 ATC Arcs (inch)
Mach2/3 ATC Arcs (mm)
Mach2/3 Arcs (inch)
Mach2/3 Arcs (mm)
Mach2/3-WrapX2A ATC Arcs (inch)
Mach2/3-WrapX2A ATC Arcs (mm)
Mach2/3-WrapY2A ATC Arcs (inch)
Mach2/3-WrapY2A ATC Arcs (mm)

If you have an Automatic Tool Changer, use the post processor with the ATC in the name. For most applications and if you don't have an ATC (automatic tool changer), use the Mach2/3 Arcs (inch) or (mm) post processor.

The greenBull 4X comes with all of the components and electronics to assemble the gantry of the machine. You will need to build the table. We provide the rails and roller chain for the X-axis (along the length of the table for full 8 feet of travel). You will need to provide some wire to connect the electronics and a computer to run the machine. You will also need to purchase the software that you will need to run the machine that matches how you will apply the machine. We suggest the mach3 control program. The CAM program is up to you as there are many options out there.

Connecting drivers from a controller to the driver does not require relays. A controller typically has pins or terminals for Step and Direction. These terminals connect to the driver's Pulse and Direction terminals. For instance for the X axis: if you are connecting from the Mach3 USB controller, you would connect the XD (X axis Direction) terminal to the Driver's DIR+ terminal, and the XP (X axis Pulse) to theDriver's PUL+ terminal, and the GND from the controller to the PUL- and DIR- terminals.

Electronics, DYI or one of our electronics kits that come assembled and tested?
Cable for the motors is a additional purchase, spindle? = silicone tubing/water pump, etc.
Cable carrier (wire management), software (also additional purchase).

No, the red mach3 USB controller will only work with mach3, you will need the pokeys57cnc. This controller will work with mach3 or mach4.

Other items you will need if you are purchasing the electronic combo (motors, drivers, power supply and computer interface) and the hardware and plans kit:

You will need the wood to create the structure of the machine. You will need a router to serve as the cutting instrument. You will need a computer to control the machine and the software that will serve as the control program. You will also need lead screws and rails (aluminum angles). If you intend to have faster travel than 20 ipm, we recommend purchasing the 5 start lead screws so you can achieve up to 300 ipm. https://www.buildyourcnc.com/item/mechanical-leadscrews-leadnuts-!5-5-starts-10-tpi

The wire that is connected to the spindle can be a simple extension cord, that you find at a local hardware store. However there is a missing wire that is required(ground) which will have to be the same amperage of the extension cord.

What wire do I need to power the spindle (ie, from the 220 outlet to the spindle). Would a dryer cable work? Is there specific amperage the wire needs?

Decreasing the speed of acceleration in the cutter? Meaning of your router/spindle?, To modify the speed of a router will be going to the router itself and modifying the speed, but if a spindle is being used modifying it will be done either manually in the VFD (VFD Setup:
Change PD001 to '0' (source of run commands)
Change PD003 to 300 (main frequency - Hz)
Change PD004 to 300 (base frequency - Hz)
Change PD005 to 400 (max operating frequency - Hz)
Change PD006 to 2.5 (intermediate frequency - Hz)
Change PD008 to 220 (max voltage - V)
Change PD009 to 15 (intermediate voltage - V)
Change PD010 to 8 (minimum voltage - V)
Change PD011 to 100 (frequency lower limit - Hz)
Change PD142 to 7 (rated motor current - Amps)
Change PD143 to 2 (motor pole number)
Change PD144 to 3000 (rated motor revolution))<- make sure these are your settings in the VFD. If the spindle is wired to the breakout board and is working through Mach 3 then the modification will be done in your CamBam/Feed rate settings.

How can I decrease the rapid acceleration of the cutter from a completed cutting operation to a new location so that the stepper motor will not lose its steps and mess up the machine zero settings? I am using CamBam and Mach3 on my machine with a chain drive. what is the best way to reduce accleration

Yes, the best way to attach a relay to the output of the Mach3 USB board is to use an SSR (Solid State Relay) at the 24 Volt rating. This is the standard supply for this side of the Mach3 USB board.
