Which Porter Cable router should I purchase? The instructions say the 800 series, but I can't purchase an entire series, and don't know the difference between them.

The 800 series of Porter Cable routers all have the same diameter; therefore, you can purchase the latest model of that series and you should be fine with the fit for our router mounts.

What is the flange diameter, and the flat to flat dimension on the spring loaded 1/2-10 lead screw nut?

Hi, the dimension flange thickness for the 1/2" 5 start 10 TPI antibacklash nut is 0.27 inches or 6.858 mm. The flange diameter is 1.5 inches or 38.1 mm. The flange has two flats that measure 1 inch or 25.4 mm from flat to flat. The drawing can be seen here: https://www.buildyourcnc.com/images/Antibacklash_nut_1_2_drawing-800.JPG Or you can click on the drawing image on the product page: https://www.buildyourcnc.com/item/mechanical-leadscrews-antibacklash-nut-!5-5-starts-10-tpi

What are the mounting hole dimensions of the 1/2" Anti-Backlash Lead Nut

Using VectricPhotoCarve and wondering what should my micro-stepping be. Presently using 1/4"

Setting the microstepping on a driver is really a function of how much resolution you want on that axis and less related to the CAM software that you use. Here is the formula for steps / inch: In this example, I will use a lead screw that has 1/2" linear travel per motor rotation. Microsteps will equal the denominator. So, 1/4 would be 4. That is how many steps per a full step. At full step, the steps for one revolution for our motors is 200, therefore steps / inch = (motor steps) / (how many inches of travel for one motor revolution) steps / inch = (200 * microsteps) / .5" steps / inch = (200 * 4) / .5" = 800 / .5" = 1600 steps/inch If you were using a timing belt, roller chain or rack and pinion, use the pitch circumference to determine the number of inches of travel for one motor revolution. If the number of teeth is 9 and the pitch is 1/4", then the pitch circumference is 2.25". Just plug that into the formula and you will get your steps/inch. You will notice a lowering of the resolution so you may want to increase the microstepping to get finer resolution.

I just bought a 3040 800 watt cnc. What electronics do i need to buy to run it?

If you do not have electronics for your CNC, you will need stepper motors (or servos) that will fit your torque requirements, drivers for the motors, a power supply, applicable wires, and an interface board for computer communication.

https://www.buildyourcnc.com/images/mach3USBCardWiringdiagram-800.jpg I would like to know the settings such as the pin number for 0 to 10V output of AVI+ and AVI- as in this wiring diagram.

The pin number for the PWM output for the Mach3 USB controller is pin #3 and O3 (out3). This setting should be specified in the motor outputs tab in the ports and pins dialog box for the spindle signal line.

how to calibrate stepper motors with ballscrews In mach3

The easy way is to use Mach3's calibration process to calibrate the axis with the ballscrew coupled to the stepper motor. This is done in the settings tab of Mach3 and clicking the button just above the "Reset" button called "Set Steps Per Unit". A dialog box will appear asking how far you want Mach3 to move that axis. Mach3 will move that axis at a distance that is determined by the existing steps per unit value set in the motor tuning dialog box (config menu -> motor tuning). Not knowing the distance that this axis will travel, it's best to use a very small value. The more difficult way and the technique that should be used to create the initial value for the step per unit in the motor tuning dialog box. Use the steps/unit formula. This example will use inches. Steps/Inch = ((motor natural steps) x microsteps) / (the travel for one complete revolution) The travel for one revolution would be the distance a ball nut will travel with one complete turn of the ball screw. This is generally the number of starts / threads per inch. Say the ball screw has 5 starts (5 threads starting from the beginning of the screw) and 10 threads per inch (TPI), then the travel for one complete turn of the screw would be 5/10, or 1/2". Say you set the microstepping to be 1/4 on the stepper motor driver and your stepper motor has 200 natural steps per revolution (1.8 degrees per step), then the total steps would be 200 x 4 = 800. So, the steps/inch is 800 / 1/2" = 1600 steps per inch Hope that helps

How do you connect a VFD with R S T to 220 power single phase?

The below information is for your convenience; however, please seek the guidance of a professional electrician that is experienced with VFDs and electrical motors of this type. A VFD (Variable Frequency Drive) for CNC Spindles that have input terminals labeled R, S and T will typically use the R and T for the Black (live) and White (neutral) connections and the PE (protective earth) will connect to ground (green). Check this image for reference: https://www.buildyourcnc.com/images/SpindleWiring-800.JPG With the YL600-2S VFD, we have found that the R and S terminals are used where the R is live and S is neutral. Connect the PE to the green ground connection. Additional Information:

hello there, i am using servo motor for my X and Y Axis but i dont know how to calculate steps/mm for that, the lead screw i am using is have pitch of .5 mm. please helpme on this i have done everything only this point is pending.

The formula for finding the steps per mm is found in the units itself. First, you mentioned that the motor is a servo. This needs to be clarified as a servo is different than a stepper motor. Some servos behave similar to a stepper motor, so I will continue with this in mind. The formula is (steps/mm): You need to find the steps. The stepper motor has a natural number of steps per a full revolution. This is typically 200 steps per revolution. The driver for the stepper motor allows you to increase the number of steps per revolution by adding a specified number of steps between each step. For instance, if you set the driver to 1/4 microstepping, then instead of having 200 steps per revolution, you would have 200 x 4 = 800 steps per revolution. So now we have the first part of the formula: Steps / mm = (200 x 4) / mm Lets determine the mm side of the formula: You mention that the pitch is 0.5 mm. Check to insure that the lead is also 0.5 mm. This could be a multiple start lead screw where the pitch is different than the turns per mm. If in this case, that the 0.5 mm is the travel for one full revolution, then you can simply plug this into the formula as: mm = .5 mm Otherwise, determine how fat the travel is for one complete revolution. Therefor, with what we know and the driver is set at 1/4 microstepping and the stepper motor has a natural step count per revolution at 200: steps / mm = (200 steps x 4) / 0.5 mm = 800 steps / 0.5 mm = 1600 steps / mm If your travel for one revolution is not 0.5 mm, then plug in your travel distance instead. Additional Information: i know about steps/mm calculation for stepper motor, because i am using servo motor that why i asked about that. please tell for servo motor. Additional Information: because its my first time with servo motor i have no idea about calculation of parameter with servo. Additional Information: Have you attempted to contact the manufacturer or seller of the servo? We typically respond to customers of our products on this customer service area, unless we have extensive knowledge of the subject and can answer the question efficiently. Additional Information:

Do you sell the cooling solution for the liquid cooled spindle 2.2kw.

We are going to add a cooling solution very soon to the website. I am awaiting inventory of Fan and Radiators. The cooling units that we will be offering are the ones shown in the two pictures here: https://www.buildyourcnc.com/images/greenbullv2-2-800.JPG https://www.buildyourcnc.com/images/greenbullv2-4-800.JPG The fan/radiator is covered up a little bit in the first picture by the vacuum hose.
