So, if I understand correctly, the stepping motor will turn on command, but the motor will only turn in one direction. Check the output of your direction signal wire. Check the wire voltage when you command the motor to turn on one direction in the planet-cnc software. Then check the voltage when you command the motor to turn in the other direction. The voltage should be different in each case.

WHAT ARE CHINA PRICES FOR COLLETS?

A cell phone emits electromagnetic radiation of various frequencies at very low intensity and would not affect the development of a fetus whose mother placed the cell phone on her abdomen during her pregnancy. The mother's reproductive and developmental risk for her growing embryo would not be altered by these exposures. If you are healthy, young, and have no reproductive problems or family history of reproductive or developmental problems, your risk for birth defects is 3% and for miscarriage, 15%. These are background risks with which every woman begins her pregnancy. Neither you nor I can change these risks. Good luck with your pregnancy.

Influenza is the most frequent cause of death from a vaccine-preventable disease in the United States. From 1990 through 1999, an average of approximately 36,000 influenza-associated pulmonary and circulatory deaths occurred during each influenza season. In addition to fatalities, seasonal influenza is also responsible for more than 200,000 hospitalizations per year. Rates of infection from seasonal influenza are highest among children, but the risks for complications, hospitalizations, and deaths are higher among adults ages 65 and older, children younger than 5 years, and people of any age who have medical conditions that place them at increased risk for complications from influenza.

A novel H1N1 virus was first detected in March of 2009 and quickly spread to pandemic levels. In the U.S., it is estimated that approximately 43-89 million persons became ill with 2009 pandemic H1N1 from April 2009 to April 2010. The virus also resulted in significant hospitalizations and deaths among children, adults 19-65 years, obese persons, and pregnant and post-partum women.

WHERE ARE THE WIRING DIAGRAMS FOR BLACKTOOTH LASER CUTTER IN INSTRUCTIONS?

BYCNC Response:
The book build was intended to be 20 inches x 40 inches. Larger machines were designed after the book build was introduced so customers would have the option to go bigger than what the book offered. Check out our larger machines on the website as the machines sizes range from 1 foot x 3 feet all the way up to 6 feet x 12+ feet.

User Response:
I'm not wanting to spend $3,000+ on a machine, I want to build one that will do a 4x8 sheet of wood. Will the plans in the book scale up?

BYCNC Response:
It is possible to scale the book build up, but the rigidity of the gantry would be questionable at that span, even if the height of the gantry structure were to be increased. The gantry design would need to be modified to become a box shape rather than a flat configuration. The kits on the site were design for those wanting a larger machine.

The motor that is attached to the 4th axis is wired as follows:

The motor should have red, green yellow and blue wires coming form the motor. The red and green are paired as one coil and the yellow and blue is paired as the other coil. You can wire the motor to a 3.0 amp driver with red to A+, green to A-, Yellow to B+ and Blue to B-

WHAT ARE THE BLACKTOOTH SHIPPING DIMENSIONS?

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.
