Most of our CNC machines have the ability to be customized by length. The greenBull 5X for instance comes standard at 5' x 10' but it is really only the gantry width that is fixed. The length can be easily altered. If you are interested in receiving a custom quote, you can email sales@buildyourcnc.com.

If the motor has 8 wires, you will need to wire the stepper motor in bipolar parallel. This motor (425 oz-in) is wired as follows:

Red and Blue wires to A+ on driver
Yellow and Black wires to A- on driver
White and Brown wires to B+ on driver
Orange and Green wires to B- on driver

how do I connect an 8 wire motor to a driver?

Yes, our greenBull is the best machine to exhibit those dimensions. The 8" z-axis travel can be achieved by making sure that the table and bed of the machine will built with a depression that lowers the work are to the desired travel and clearance depth.

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.

On the following webpage:
https://www.buildyourcnc.com/item/electronicsAndMotors-electronic-component-breakout-Mach4-mach3-USB-ethernet-Board
there is a diagram with all of the connectors shown. Each connector has the pin number displayed next to the pin. In Mach3 or Mach4, cgo to the plug-ins configuration for the Pokeys57CNC controller and go to the key mappings and select the pin number you would like to use and modify its function by click on the down carat to see all of the available functions.

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.

Next time, purchase the drivers from us and you will have fewer problems.

To add CO2 laser functionality to your existing CNC machine, you will need everything listed on this page: https://www.buildyourcnc.com/LaserComponents.aspx

The number of mirrors and mirror mounts will depend where and at what orientation the laser tube will be mounted in the machine. There is already a mirror mount in the head/nozzle unit, so keep that in mind.

A separate power supply is not needed for each stepper motor. If the combined amps requirement is very high, I typically use more than one power supply. Say, the combined amp requirement is 18 amps, I will typically use two 10 amp power supplies.

The motor is creating it's own EMF when you try to turn the shaft manually. When coils are connected (or not connected) to any circuit that is not powered can cause unpredictable results.

The motor freezing from just turning it by hand with no connection is surely the wires touching each other. This is actually how we test if a motor is good or bad. If the motor freezes when two of the wires are touching, that means the motor is functioning properly since the magnets are causing current to flow through that coil opposing the magnet.
