Question: heavy duty 4x8 od z tower height /thanks

Current Solution

The Z axis travel on the heavy duty 4x8 greenBull CNC machine is 8 inches.

Respond:

My Z motor only goes in the up direction
The wire that connects from the CNC controller to the stepper motor driver that is responsible for direction (called DIR, or CW) is not connected, or not connected well. This can be true for the positive direction terminal or the negative direction terminal.

Additional Information:
I checked the connections all appear to be secure. I completely turned off all systems, restarted, and the problem went a way. ??? not sure why.

Will the Spindle Z plate fit the Blackfoot v4.1?
The long wood piece that attaches to the Z-axis may have different dimensions on the newer blackFoot version. Take a measurement of your current length of the long wooden piece and tell us what it is so we can compare them. customerservice@buildyourcnc.com
