ROLLER CHAIN LENGTH GREENBULL**WHAT ARE THE DIMENSIONS FOR GREENBULL TABLE?**Actual table dimension: 4'x8' is 56.078"x 121.50" (the overhang in the illustrations should be 3/4" thick)

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.

WHAT CABLE LENGTHS SHOULD USE FOR THE BLACKFOOT CNC MACHINE**CAN THE GREENBULL CUT 18MM BIRCH IN ONE PASS?**If you use the 2.2kW spindle, it can cut at 3/4 inch or 19 mm deep with at least a 1/4" cutting diameter single flute end mill. You will get better results with larger diameter end mills, but that is the worst case scenario. I still recommend doing a finishing pass on the edge to make sure everything is perfect.

CAN THE GREENBULL CUT 18MM BIRCH IN ONE PASS?**GREENBULL 5X10 X AXIS SHUTTERS**If your axis shutters and will not move unless moved by another force, that sounds like your acceleration is set too high. Lower the acceleration until it works well, then lower it a bit more to have a margin of safety.

Users response:

I've lowered my acceleration to 1 in the StepCon program and it still shutters when I jog it, anything else I could check?

Buildyourcnc response:

IF that didn't work, try swapping the X and Y drivers. That way you will pinpoint if the issue is the driver. If the proplem persists, then there may be an issue with the motor itself.

Buildyourcnc response:

The X and Y drivers can be easily swapped by swapping only the motor wires.

- Remove the x-axis motor wires from the X driver.

- Remove the Y motor wires from the Y driver.

- Insert the X motor wires into the Y driver.

- Insert the Y motor wires into the X driver.

Buildyourcnc response:

Now the Y-axis will move the gantry. Test the Gantry movement by moving the Y axis using the up and down arrow keys (mach3).

Users response:

Problem is now solved, I switched the X and Y at the redFly and got the same problem, so then I undid the wires going to each motor and switched them there and it I had a bad solder point in the X axis connector, thank you for the help

Buildyourcnc response:

You're very welcome. We will make sure to thoroughly check the solder points on the cable connectors prior to a redFly delivery.**Click the link to add information to this solution:**

GREENBULL 6X SILICON TUBING**WHICH MACHINE SHOULD I BUY, GREENBULL OR BLACKFOOT?**The greenBull can range is routing width sizes of 5 feet and 6 feet. The blackFoot has a 4 foot routing width.

Previous Solution:

The greenBull machine has a sturdier gantry than the blackFoot, so you can be more agressive with the cutting feedrate (cutting speed). The blackFoot is also a good machine, but it all comes down to the speed at which you want to produce the fabrication

The spindle is also highly recommended for it's quietness and easier cleanup (no fan blowing the dust in the air)
