  • Why is your 3/8" acme thread only 2 start and your 1/2" is 5 start?

    Dealing with our 3/8" ACME screw, we intended to use this with a 3D printer machine(primarily) as well as our smaller motors. Which did not need the increased torque ratings as our larger motors, which will use the 1/2" ACME screw with larger machines.

  • wHAT IS THE SMALLEST LENGTH SHAFT I CAN USE FOR YOUR #25 DRIVE SPROCET?

    The hub length of the drive sprocket and the other mechanical devise that is used to connect on the shaft will determine the length of the shaft needed for use with the drive sprocket.

    The hub lengths for our drive sprockets are 1/2". So if you are connecting the drive sprocket to a motor, your motor shaft will need to be at least 1/2" in length.

  • I just changed my X and Y to the ACME 1/2" 5 start lead screw. What are the motor tuning numbers. I have the book built machine.

    The settings that will have to be change will be your steps per inch in motor tuning (mach 3), or settings/axes(planetCNC). But we do not have the actual numbers/specs that will fit your 10 TPI 5 start lead screw, here is a tutorial video which explains how to get the exact numbers you need! (

  • DO NEED LIMIT SWITCHES, IF SO WHAT IS YOUR RECOMMENDATION?

    Limit switches are not really needed for this level of a machine, but if you do want to use them, then you will need to connect them with shielded cable and ground the shield at both ends and any other non-used wire in the cable. Limit switches are very susceptible to the motor interference. You will also need to adjust the debounce in the software you will use.

  • If I order 19ft of the 1/2" lead screw will it come in three 6'5" lengths by default? This is what I need. Thanks

    No they will not come in that length as a default, we would contact the buyer to ask specific lengths due to the total length purchased.

    However if you order the 1/2" lead screw we can get them cut to the specific length you require, by contacting us here or call us at 281-815-7701.

    Summary - Mach3 versus Mach4 :
    Mach4 Hobby is the closest comparable version to Mach3, yet it is still much more advanced. The price point of these versions is nearly
    identical. Mach3 is very popular for hobby enthusiest and is used in highly modified form by some great OEM's. In general, Mach4 is more
    complex than Mach3 and follows cnc industry standards. Mach3 has many customizations to make it easier for hobby users, but can lead to
    difficulties if users plan to apply their knowledge to more advanced systems. Mach4 is built as a full featured cnc controller capable of high
    speed machining for servo and stepper systems. Mach3's feature set is complete, while Mach4's will continue to expand. If you are new to cnc,
    Artsoft highly recommends using and learning Mach4 even if it appears that Mach3's feature set will be adequate for your needs.

  • WHAT IS THE DIFFERENCE BETWEEN ROCK CRYSTAL ?

    The first number is the amount of chromium that is contained in the stainless, i.e., 18 is 18% chromium. The second number is the amount of nickel, i.e., 8 stands for 8% nickel. So 18/8 means that this stainless steel contains 18% chromium and 8% nickel. 18/10 is 18% chromium and 10% nickel. The higher the numbers the more corrosion resistant the material. 18/0 is a misleading designation. Both 18/8 and 18/10 contain nickel and are part of the grade family "300 series" stainless. 18/0 means that there is 18% chromium but zero nickel. When there is no nickel the stainless grade family is the "400 series". 400 series are not as corrosion resistant as the 300 series and are magnetic, where the 300 series are non-magnetic.

  • WHAT IS THE DIFFERENCE IN A 2.5 AXIS MACHINE?

    An axis is a direction of motion controlled by the CNC machine control. It can be linear (motion along a straight line) or circular (a rotary motion). The number of axes a machine has determines it's machining capabilities. A 2.5 axis machine really has three moving axes, but only two axes can move together (most machines sold today are full three axis machines). For machining centers, a three axis machine will have three linear axes. A four or five axis machine will have three linear axes as well as one or two rotary axes.

    Note that 2.5 versus 3 axis has yet another context. 2.5 axis machining requires that the machine have three axes, but only two axes must be moving simultaneously at any one time. (Simple operations, like drilling and most milling, fall into this category). On the other hand 3-axis machining requires that all three axes be moving at the same time (More complex operations, like the machining of sculptured surfaces required in molds and airfoils, fall into this category.)
