Everyone always assumes they are doing something wrong when a plant fails to perform to their expectations. Grapes need pollinator activity to set viable fruit, but there is a shortage of bee activity throughout the country. When the flower cannot be pollinated by bees, the resulting fruit usually atrophies. It is not your fault, just a shortcoming in nature's network.

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.

If I purchase a greenBull 6X Long Z CNC Machine Kit and Mach3, what else would be required to assemble the working machine? I have CAD software.

Other items you will need if you are purchasing the electronic combo (motors, drivers, power supply and computer interface) and the hardware and plans kit:

You will need the wood to create the structure of the machine. You will need a router to serve as the cutting instrument. You will need a computer to control the machine and the software that will serve as the control program. You will also need lead screws and rails (aluminum angles). If you intend to have faster travel than 20 ipm, we recommend purchasing the 5 start lead screws so you can achieve up to 300 ipm. https://www.buildyourcnc.com/item/mechanical-leadscrews-leadnuts-!5-5-starts-10-tpi

I recently purchase the BlackToe v2.1 (4x8) at a local school auction. The table is complete, however, it is missing the spindle and came in 4 (four) separate pieces. Are there plans for this machine that I would be able to use to reconstruct and determine if anything else is missing.

If you read the description the first uses a parallel interface for computer hookup. The second uses USB interface for computer hookup. The third utilizes an integrated computer which is built into the package thus you do not need an external computer.

What is the difference between the 3 Blacktooth laser packages offered? Specifically, one with/without a computer? Why do I need one? Also, is the $2100 assembled vs the $1700 which is not? What am I paying $400 more for?

Can you check if there are cracks in the inner glass tube? Also, check to see if there is water between the inner glass tube and the outer glass tube. That will give you an indication of cracking in the inner glass tube.

I was in the process of aligning mirrors for our vertical XL and suddenly the laser does not fire anymore, there is an arcing sound and a light near the Anode (positive) connector of the tube on the very inside. Do you think the laser tube would go bad so quickly? how could we avoid this?

We have not had any issues with stock firmware on the AWC708lite. Upgrading the firmware will be at your own risk. We can contact our supplier and see if they can provide a suggestion for updating firmware. Contact customerservice@buildyourcnc.com to inquire with a person who can help.

Yes, it is feasible to create a machine with a cutting area of 13'x15'. Your mechanical and structural systems will need to be able to span a bit more than the 13' if that will be the axis travel along the gantry.

We have not cut carpet with our lasers, but I don't see why not. With that said, be extremely careful with the materials in the rug. Read the MSDS (Material Safety Data Sheet) for the rug you intend to cut as some materials will emit corrosive and harmful gases and chemicals when lased.

Hi I want to build a cnc laser table 13'x15' cuttting area. Is this feasible. Also would the 80watt laser be enough power to cut through carpet

The largest CNC machine we make at this time (12/04/2015) is the GreenBull 6'x12' model. This model has 2 options for Z-axis travel.

The short-z option has a total Z travel of 5.75 inches. From that you would subtract the length of the end mill used and the thickness of the spoil board to determine the maximum material thickness. (Example: If the end mill extends 1.25" from the collet and the spoil board is .75", then the material could be up to 5.75 - 1.25 - 0.75 = 3.75 inches in thickness). This is good for most sheet-type materials.

The long-z option, used mainly for large 3D carvings, requires a custom frame and allows for up to 36" of travel.

The tolerance of our machines, like any machine, depends on several variables. The major variables include the manufacturing tolerance, the type of machine control used, the precision of assembly, the thoroughness of maintenance, and the initial and ongoing calibration of the machine. Because we sell kits only most of these variables are outside our control. Therefore, we are hesitant to guarantee a certain level of tolerance for an end user. However, in our experience, tolerances of .001" are readily achievable with our machines.

What tolerance can I expect from your largest cnc machine and the laser cutter? Also, what depth can I get on the z axis?

Dealing with our USB BoB, it is really similar to the MK1 board, but is also loosely based on their DIY board as well. We have not seen that much of jitters or jerks, that we have noticed here while fabricating and testing the boards. We have not heard that many issues dealing with the board about abnormalities in running, unless we have not been notified in regards to customers who have used them under continuous use.

Click the link to add information to this solution:
Its mentioned that your USB Breakout board is based on Planet-CNC's MK1 board. Planet-CNC on their forums mention that they've discontinued their MK1 because of a low buffer memory which caused jitters and jerks in the machine? Am I likely to face a similar problem with your board?

BUILDING ONE OF YOUR GREENBULL 6X LONG AND 2.2 KILOWATT SPINDLE DOES NOT FIT. SEEMS LEAD SCREW YOU SENT WITH KIT IS SHORT 42" LOOKS LIKE IT NEEDS TO BE 5 OR 6 INCH LONGER. THIS CORRECT? WHAT THE NEEDED LENGTH FOR UNIT?

The frame size difference of the NEMA 23 and 24 is very slight and, depending on the motor mount both will most likely fit. The bigger difference between these stepping motors is the torque. Make sure that the motor that you purchase has the appropriate torque for the axis that it will move.

Is is safe to go with the higher torque? Or if the torque is too high for what i need is that bad?

You can use a motor with higher torque. Just make sure to select the correct driver for that motor.

Additional Information:
The frame size has nothing to do with torque. Nema 23 means a 2.3" frame. Nema 24 means a 2.4" frame. That's all. Either could have more or less torque depending on speed and power.

A couple things to consider, the machine is most likely moving sideways, so the bristles won't be a problem. The lead screw has a very hight mechanical advantage and the bristles don't pose an issue with this. We have not found that the bristles cause any appreciable deflection to the work we do in our shop; however, you can change the brush for a more pliable plastic, or reduce the number of bristles by selectively pruning.
