Do you have a TL or a TH for triggering the laser? If you power the digital side of your laser power supply with 12V and tie the gnd with the PWM gnd on the pokeys57CNC controller, you may be able to use the PWM on the pokeys57CNC controller. Before you do this, I would suggest that you contact polabs support (http://support.polabs.com/) and ask them if this is possible.

Only our greenBull CNC machines will be able to use the long Z-axis, due to structural construction of the greenBull over the blackFoot.
The height from the table top to the bottom of the gantry is: 4.25"

Both the maximum cutting height and diameter, will be dependent on the specific end mill/router bit you plan on using, since they can vary in length.
The maximum cutting height (useful to engrave or cut material)is: with spoil-board 3.875", without a spoil-board is 4.625"
The maximum diameter will (estimated) is: 3"

Specifically dealing with our greenBull long Z-axis CNC machines, depending on how you specifically design the table you can have more cutting height and a larger diameter clearance. If you only create a frame for the machine with a hollow center(adjustable midsection), allowing you to have a greater clearance.

There are many ways to wire an emergency stop switch. The simplest, and arguably the most certain, way is to wire the switch into the incoming power so that throwing the switch kills all power to every part of the machine. Here is a diagram showing how a customer wired such a switch on their blackTooth laser which you could adapt to your needs. http://www.buildyourtools.com/phpBB3/viewtopic.php?f=12&t=4872

Alternatively, you could use an input pin on your USB board. The wiring would depend on whether and how you might be using limit switches (single or multiple switches; normally open or normally closed). Our website datasheet for the USB board is at https://buildyourcnc.com/item/electronicsAndMotors-electronic-component-USB-Controller-Breakout#prettyPhoto/2/ and shows how to configure the switches for each set up. If you use this method, you'd essentially wire the e-stop as a limit switch.

The laser mount for the greenBull is designed and suited for a 40W tube only. The 80W tube is too large to mount on the gantry.

The following videos are helpful when connecting the VFD to a pokeys57CNC controller; however, there is useful information on the external terminals of the VFD and how to connect the VFD to any controller using a relay. Additionally, the videos have useful information on how to program the VFD.

The Greenbull machine can cut a very wide variety of materials ranging from foam to aluminum. We recommend the use of our 2.2kW spindle to allow the greatest flexibility. Aside from that, the most important thing is to use an appropriate end mill for the material you are cutting and to use appropriate speeds and feed rates.



BYCNC Response:
Our 40W laser can cut up to about 1/4" materials ranging from wood and acrylic down through lighter materials such as leather, fabric, foam, etc. Speed and final cut are greatly enhanced by an air assist upgrade. We also offer an 80W laser which has approximately twice the capabilities of the 40W.

Since this 4th axis already comes with a stepper motor, you will need a driver and some cable to connect to the driver from where the 4th axis will be placed. If you have extra space in the redFly electronics enclosure, you can fasten the driver there. You will also need some wire to connect the driver to the breakout baord.

Unfortunately we no longer include or sell our CNC plans for none of our machines. We will be here to assist you if any parts wear over time, and will be able to replace the parts if needed.

Charges may be subjected due to time of purchase and cause of wear.

Here's a link to the blackTooth laser that we sell, https://www.buildyourcnc.com/blackToothLaserCutterAndEngraver.aspx. It will vary depending which materials you are using, but keep in mind on how deep you are cutting since the blackTooth only cuts 1/4" inch(dept) at a time.

You will need to build the table unit for your machine. There are instructions on how to do this at the bottom of the product page here, https://www.buildyourcnc.com/Item/cnc-machine-blackFoot-v4
There is no estimate on how much this will cost though, since there are too many variables involved to do this.

- PC with parallel port and USB port
- 20awg stranded wires for the motors - http://www.buildyourcnc.com/electronicscombo.aspx
- 18awg stranded wires for power supply to drivers
- 24awg stranded wires for breakout board to drivers
(location and spacing of components varies from one person to another, so we do not provide cables/wires)
- General purpose extension cord (cut the female end off) to provide power to power supply
- USB cable to power breakout board
- Parallel cable to communicate to breakout board
- Router
- (optional - instead of router) Spindle with power inverter http://www.buildyourcnc.com/SpindlesAndAccessories.aspx
- (if purchasing spindle with inverter) General purpose extension cord (240v) (cut the female end off) to provide power to power inverter
- End Mill(s) http://www.buildyourcnc.com/ProductsEndMills.aspx
- CAD, and/or CAD-CAM software (to produce geometry, machine operations, and g-code) http://www.buildyourcnc.com/CNCsoftware.aspx
- CNC control software (to read g-code and control machine) http://www.buildyourcnc.com/CNCsoftware.aspx

This answer is applicable to most of our machines with the exception of the greenLean and the blueChick since those machines are equipped with a table structure.

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.

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.
