### Question #: 979

Question:
**
what are the system requirements for the Linux CNC (EMC2)?
**

**
**

**The Linux CNC (EMC2) does not require a high performing computer. This application will run fine on a Pentium or later computer system. You will need a parallel port as either part of the motherboard, or as an adapter that plugs into one of the motherboard PCI slots.Additional Information:20**

I need a working area of 12"x24"**How feasible would a vacuum hold-down system be for a vertical CNC like the greenLean?**Building a vacuum table, for any CNC machine is possible but doing it right might take a adequate amount of information and extensive planning. Depending on the overall complexity you want to build.

Example, you want sections, and valves that can be operated to close sections of the table to allow vacuum to a specific spot of you material.

It is possible and would be a very precise method to hold down your material.

WHAT CABLE LENGTHS SHOULD USE FOR THE BLACKFOOT CNC MACHINE**While motor tuning what are the recommended steps per inch, velocity, and acceleration for the GreenBull CNC?**In the customer service live, just enter "motor tuning" and it will give you a list of all the recommended or default settings for our machines. However the acceleration and velocity for the greenBull(other machines) will be an actual determination on your trials. You will want the highest possible acceleration and velocity without the motors stalling, so you can do increments of ten to be on the safe side, if it is too slow try increments of 25.

The steps per inch is dependent on the microstepping:

Steps/Inch for the x and y

Steps = 200 motor steps per revolution x 16 microsteps = 3200 steps

Inches = sprocket number of teeth x pitch of the sprocket = 14 x .25" = 3.5 inches

steps/inch = 3200 / 3.5 = 914.28

This is really a starting point. You will then need to use the mach3 calibration function to get the perfect steps/inch value. Use as long a measurement as possible when calibrating.

Velocity:

Start with a value of 1000 ipm. Increase this value with a relatively low acceleration at about 10. You will notice at a particular velocity that it will stall. This is your stall velocity. I would take the stall velocity and reduce it by about 30% to 50% which should give you a good final safe velocity.

Acceleration:

Once the velocity is found, raise the acceleration until it start to stall at a low velocity. Reduce the acceleration by about the same percentage to stick with a safe acceleration.

The acceleration is mostly dependent on torque (current) and the top speed is dependent on the amount of voltage.

Give some tests with all of the axes running at the same time. If you notice and stalling, reduce velocities and acceleration depending on when the stall happens (top end, or acceleration curve).

To determine the frame dimensions, first consider using the frame height shown of almost 3' (2.86'). The width of the frame should be 4" narrower than the dimension from rail edge to rail edge (6X rail to rail is 80.078"). This will provide a 2" overhang on both sides (4X frame width should be 56.078").

The length of the frame should be 4" shorter than the desired length of the rails to provide a 2" overhang on both ends. The travel length will be 20" shorter than the rail length due to the space occupied by the gantry sides.

Two long pieces of 3/4" material will need to be placed on top of the frame with the 2" overhang on the sides and the end. These long strips of material will receive the rails and the chain mounts on the ends.
