I would recommend wiring the E-Stop to an input terminal via an NC connection. This is the industry standard. It requires a NC (Normally connected) circuit for the machine to be operational, and when the circuit breaks, the machine shuts off. This is better than having a circuit NO (normally open), open circuit that requires a circuit to be created to have the machine shut off for safety.

Having en E-Stop run through the mains line would only work for a single circuit (or use multiple E-stops, which defeats the purpose). The E-stop connected to the input terminal would shut off all machine functions.

100% agree. When we have our automatic fire suppression systems wired in, we always do them NC (Normally Connected/Normally Closed).

How should I wire the 2.2kw spindle and vfd?

The type of wire that should be used between the spindle and the VFD (Variable Frequency Driver also called the inverter) should be of stranded type and we use between 18 and 16 AWG.

The total current is divided among the three coil wires, therefor a wire gauge of 16 should be sufficient.

Currently we use 20AWG 4 conductor.

If you are using the AWC708 or equivalent laser controller, the limit switches will connect between the EL input terminal and the GND terminal in normally open (NO) connection. Most limit switches can be connected as NO, or normally closed (NC).

For instance, a limit switch for the X- limit will be connected from the ELX- terminal to the NO connection of the limit switch, then a connection from the GND terminal on the laser controller to the COM connection to the same limit switch.

HOW MUCH MOTOR CABLE SHOULD PURCHASE FOR THE BLUECHICK

The greenBull can range is routing width sizes of 5 feet and 6 feet. The blackFoot has a 4 foot routing width.

Previous Solution:
The greenBull machine has a sturdier gantry than the blackFoot, so you can be more agressive with the cutting feedrate (cutting speed). The blackFoot is also a good machine, but it all comes down to the speed at which you want to produce the fabrication

The spindle is also highly recommended for it's quietness and easier cleanup (no fan blowing the dust in the air)

CP+ to COM
CP- to STEP
CP+ to CW+ (small jumper wire)
CW- to DIR

Additional Information:
If the driver does not have CP or CW labels, the CP is Step and the CW is Direction or DIR. If you connect the 5v to CP+ (or Step+) and CW+ (or DIR+) and the pin to CP- (or Step-) and another pin to CW- (or DIR-), then in software, the configuration for the step on that axis must be active low. Otherwise, if you connect the GND to CP- (or Step-) and CW- (or DIR-) and the pin to CP+ (or Step+) and another pin to CW+ (or DIR+), then in software, the configuration for the step on that axis must be active high.

Additional Information:
If you have a driver that is labeled pul, dir and ena: Pul+ is the Step+ and Pul- is the Step-. Pul is short for pulse. A pulse will create a step. Don't worry about the enable terminals.

On the x-axis, pin #2 can go to pul- and pin #3 can go to dir-. The 5v will go to pul+ and dir+. The configuration for each axis for step will be active low and toggle active low for the dir on each axis to make it go in the direction desired.

HOW DO I WIRE FROM THE BREAKOUT BOARD TO DRIVER?

Yes, you can use 2 motors in the same axis output, however you will still need a driver for that stepper motor. Also depending on the orientation on which you mount the motor you might have to invert the direction of the motor, and that will be simple by swapping the A+,A-, to the B+,B- locations and vice versa, from the driver to the motor wiring.

The wiring scheme would look like this:
The step and direction output terminals on the CNC controller interface for the axis you want to have two motors would connect to both drivers of the two stepper motors on that axis.

Additional Information:
I have been running two motors from the same driver for 10 years on my 3m x 1.6m router. Both motors driving the gantry are wired together. I see no reason to use two drivers. The motors are high torque Nema 34. I've had no issues.

How do I wire two motors on the same axis?

This will depend on the 3D printer that you are using and the mechanics involved. Specifically regarding the motor drivers, software is really what determines the speed of the motor. If the computer is not able to product the high number of pulses that is required for faster motion, then you can reduce the microstepping and configure the software appropriately for the new microstepping so the resolution is corrected (steps/inch or steps/mm).

The motor that is attached to the 4th axis is wired as follows:

The motor should have red, green yellow and blue wires coming form the motor. The red and green are paired as one coil and the yellow and blue is paired as the other coil. You can wire the motor to a 3.0 amp driver with red to A+, green to A-, Yellow to B+ and Blue to B-

There are several specifications related to CAM software that you will need to consider.

1. The CAM software will need to be able to offer the features that match that of the machine you select to perform the fabrication. Some of these machines include, standard 3 axis vertical CNC milling machine, turning machine, and 4 or 5 axis CNC machine.

2. The CAM software will need to contain the features that you feel are necessary for how you will apply the machine. For example, are you making signs? Are you milling parts for a machine? There is a wide array of CAM software that will work well for one application and not another.

3. The CAM software will need to work well with your workflow and processes, and have the user interface that you prefer.

Vines are normally planted bare root from January to March and spaced 7 to 8 feet apart in rows 10 to 12 feet apart. Vertical stakes or posts with 1 or 2 wires on the side, or with “T” tops with wire are desirable supports for grapevines. Cane prune Thompson seedless and Concord. Spur prune other varieties. Frost (31oF) damages new shoots and fruit clusters in April or May, so plant where the frost is minimized. Spraying or dusting sulfur for mildew is necessary on wine and table grapes, but rarely needed with American types. (From http://ucce.ucdavis.edu/files/filelibrary/40/935.pdf )

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.
