The amount traveled per turn in our blackFoot, will be dependent on the steps per inch settings that you will implement to your drivers and within the software (mach3 (ex)) motor tunning: steps per inch/ 1422.22, 1/4 on your driver will give you a different distance if used as 1/2 or 1/8 etc.


Here is a in depth tutorial on how to find the correct steps per inch for a specifications: (

How far does the X axis of the blackfoot travel per turn of the stepper motor ?

The blackfoot requires a total of 50 feet of cable.

The X axis needs 15 feet
The Y axis needs 17 feet
and the Z-axis needs 18 feet

These are 20 gauge 4 conductor cable.

We don't offer the dxf files for the parts of our machines; however, if you purchased this machine from us in the past, and you wish to cut this part on your machine, you can call our office and request the dxf file. We will provide an NDA for this type of transaction.

It is not recommended that standard routers do full depth passes. This is better done with a spindle. For best results with routers, we recommend a depth that equals the cutting diameter of the end mill. The IPM will relate to the chip load of the end mill (look up the formula online and add it here). The IPM will also depend on the end mill diameter, the larger the diameter, the faster the feedrate. A 1/2" end mill can cut about 300-500 ipm where a 1/4" end mill will be able to cut at 80-120 IPM, at a depth equaling the cutter diameter using a router. With a spindle, the same feedrates can be applied, but with more depth per pass. For instance, an MDF full depth cut at 3/4" can be cut at the 100 IPM using a 1/4" cutter.
Here is a basic setup we have for our blackFoot (default setting):
X-Axis
SPI: 914.29
Acc: 400.02
Vel: 5
Y-Axis
SPI: 1422.22
Acc: 400.02
Vel: 5
Z-Axis
SPI: 1600
Acc: 400.02
Vel: 79.98

I have a BlackFoot with a 3.25hp Porter Cable router. What is a safe starting IPM to optimize feed rate? How fast do you guys run full depth passes through MDO or MDF?

The motor cables for the blackToe are as follows:

Total 30 feet

X - 9
Y - 10

Yes, we have the optional table for the blackToe, but we need to fabricate it, which only takes one day. We generally reserve one week for the total fabrication and packing of all parts.

CamBam specifically creates the g-code (machining operations) instructions to be loaded into Mach3. Make sure in your CamBam g-code file parameters, you are using the Mach3 post processor. If you have already done this, let me know. If you are not sure how to do this, let me know.

I am having trouble connecting the cambam program with my Mach3 to my 4X8 Blackfoot CNC machine. Where can I get help on this issue. Have had my machine since 2015 and have not been able to use it. Thank you

If you are using Mach3 do you have your hotkeys set up correctly?

I got my Blackfoot 4.3 built. Hooked it to the Redleaf and when testing the axis controls Im able to move the X axis using the Right arrow key, but unable to move it with the left key. I have no control on my Y axis. Tried calling for tech support and recieve voicemail 2 days in a row after a few calls each day.

The eyebolts are used in the squaring of the machine. I would use a standard carpenters square and first run the end mill along the edge of the square to first make it parallel with the long axis. Then run the end mill along the other edge with the short axis and adjust the eye bolts and chain according to the angle that the machine is out of square.

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)
