Hi Patrick What is the name of that organization for CNC enthusiast in Houston and Katy TX and phone number please. Thanks

The plans/hardware/electronics/mechanical includes everything but the wood structural components that can be cut by the customer. This plans/hardware option includes all of the electronics, like motors, drivers, controller, and all of the cables and wires to connect all of the electronics together. The mechanical components include shafts, couplings, linear rails, bearing blocks, sprockets, lead screws, etc. The hardware consists of all of the screws nuts, insert nuts, cross dowels, etc, to assemble all of the structural, mechanical, and electronics together.

If you want to run a greenBull CNC machine using a generator, The generator will need to allow for a minimum amount of current draw. Here is a list of items that draw current and how much current (the list does not include the laser option):

Spindle: 10 amps minimum so plan for more.
The power supply for three motors and drivers: 9 amps
The computer to run the control software: varies but out redleaf system would be a max of 2 or so.

So you are looking at about 21 minimum so you will probably need a 25 amp generator.

Can I run your greenBull CNC off of a generator? If so, what specs would you recommend? Thanks!

You can always come to our offices in Katy TX. If that is not an option, we can do cut in our shop and record video for you. Specify what you would like to cut and we can consider doing this for you.

Thanks. I've reviewed the gallery and think my question comes down to this- Can I do hardwood carving like Mike M.'s guitar display cases and cut 3/4 inch baltic birch plywood with the same machine?

Absolutely, the cutting and machining is more a function of how the machining operations are created and specified. Baltic birch is not a tough material and you will be able to cut very aggressively with any of our machine kits.

Where is the best place to see projects made with BuildYourCNC CNCs? I would like to get an idea of carving capabilities and cutting Baltic Birch plywood. Thanks.

If your computer does not have a parallel port, all you will need is a low cost PCI parallel adapter card (these can be found on amazon for $15-$20). If you plan on using a laptop (not recommended) you can try to find a PCMCIA parallel adapter, but many people have frequent issues with this setup. A more expensive solution would be to purchase a USB smooth stepper board. Unfortunately, we do not supply any of these adapters and cannot attest to their reliability.

Our hold down method is screws. For a 4'x8' 3/4" sheet, we use 6 screws around the perimeter of the sheet. This provides sufficient hold down for milling. For the vertically oriented machine, the sheet also rests on a small ledge, making it easy for the board to maintain position while fastening.

Can the vertical CNC router do about what a horizontal router can, like cutting out 3/4" cabinet doors from a 4'X8' formica clad sheet? If so, how do you hold it - with Vacuum? Is a vacuum system available?

That will depend on the controller that was installed in the redFly. If the controller is a pokeys57CNC controller, you can use Mach 4 with that system.

You can add a 4th axis and an ATC (Automatic Tool Changer) with the redFly system.

Does the Redfly that I bought with the GreenBull in 2016 work with Mach4? Also I want to add a 4th axis and a spindle with automatic tool changer. Will this work too or do I need a new control board? I bought my CNC with a longer Z travel, so I have plenty of room for these. Thanks!

The formula and calculation is a starting point to get into the area of steps per inch. You will then need to use the mach3 calibration utility to get the exact steps per inch.

Formula:
step per inch = (motor steps * microstepping) / (travel at one turn of the motor in inches)
if microstepping is set at 16 (1/16 on the driver) then and you are using a sprocket and chain with a pitch of .25 inches and 12 teeth on the drive sprocket
= (200 * 16) / (12 * .25)
= 3200 / 3
= 1066.666 steps per inch

For lead screw that has a travel of .5 inches at one turn like the 5 start 1/2 inch lead screw and using 4 microsteps per step (1/4):
= (200 * 4) / (.5)
= 800 / .5
= 1600 steps per inch

Remember to use the mach3 calibration wizard and double check the driver microstep setting.
