The specifications for our 3/8" bearings are R6ZZ. The ZZ means double metal shielded. The metal shielding is to protect the ball bearings between the inner race and outer race.

Inside diameter: 3/8"
Outside Diameter: 7/8"
Width: 9/32"

Depending on the size of your CNC machine, it will vary the length required for your application.
Please verify the CNC machine, and we can go into detail on the specific lengths or methods for the linear guide mechanics.

We sell our ACME Screw (1/2" per inch), also our longest length of ACME Screw is 76-3/4".

The lens is 20mm wide and a 50.6mm focal length (the one included). This lens will stand up to at least 30PSI air assist.

The mirrors are 25mm wide mirrors.

Focal length is the distance from the lens to the material for the laser converge into the best focal point. If a lens is listed as 2". You measure 2" from the lens to the material, this will be the tightest point the laser can go before it starts to re-expand again losing focus.

WHAT ARE THE BLACKTOOTH LENS SIZES AND FOCAL LENGTH SPECIFICATIONS?

There is very little radiofrequency (RF) energy exposure to people inside a building from a cellular base station located on its roof. There are several reasons for this. First, the transmitters operate at low power levels. Second, the antennas are normally mounted near the edges of the roof and are aimed away from the building. Third, most cellular transmitters use "high gain" or panel antennas. Such antennas transmit most of their energy in a narrow beam (in the vertical direction) from their front surfaces, away from the building. They radiate very little energy downwards towards the roof or backwards from their rear surfaces. Finally, building materials absorb a significant fraction of the RF energy passing through them. As a result, the RF signal levels at any location inside the building are invariably low and far below safety limits. The situation might be different in some locations on the roof itself. RF signal levels close to (within a few feet) and directly in front of cellular base station antennas can easily exceed safety limits. Some precautions are needed to prevent people from walking directly in front of the antennas while they are transmitting. This applies also to paging and other systems that use rooftop antennas, some of which transmit at higher power levels than many cellular base stations. Kenneth R. Foster, Ph.D.

Depth of Field. This is how far the focal point goes before re-expanding again. With a 2" lens, you have approximately 2-3mm of DOF. This means that you'll have 2-3mm of perfectly focused laser before it starts to re-expand again. If you have a 4" lens, you will have up to 7mm of DOF.

WHAT TERMINALS ARE USED TO CONNECT THE INVERTER WALL OUTLET?

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.

Yes, you can use any two of the output terminals of the breakout board to control the SuperPID closed loop router controller (a diagram is not needed with these instructions).

One output terminal will be used as an on/off (1/0 or 5v/gnd) that will be invoked with the M3/M4/M5 M-codes in your g-code instructions.

The other terminal will be connected to either another 5v/gnd signal to control speed for 5000/20000 rpm or for PWM output (recommended) for proportional speed control.

To setup this configuration in Mach3, go to your ports and pins dialog box (config menu -> ports and pins). Click on the spindle setup tab. In the Motor Control Section of the dialog, check the box for Use Spindle Motor Output and check the box for PWM control. Change the PWM Base Frequency to 50Hz.

WHAT ARE THE ROLLER CHAIN LENGTHS FOR GREENBULL 4X

The parallel (printer cable) port is uses the computer as its main source of pulse trains to operate the motor driver directly. Parallel ports are a direct connection from the processor commonly referred to as GPIO pins (General Purpose I/O pins) and provides a convenient and powerful way to interface with the computer. The parallel breakout board is included in those kits only to condition those signals for use with the drivers.

The USB serves at the actual controller, sending the pulse trains, but the computer sends simple human readable instructions to the USB controller to tell the controller how to send pulses.

The non-technical differences that may serve as the most important information to you is that the parallel configurations allow for a wider variety of industry standard software that can be used to control the cnc machine. The USB that we offer requires the operator to use a software called Planet-CNC software which is a very well made and feature full cnc control software.
