Cable Carrier - Inside Dimension 1 inch by .75 inches

With your 120v drive systems for your 2.2kw spindles, do you do something to limit the output to the spindle so that the current draw doesn't exceed the 80% limitations of a 20a circuit? I have a dedicated circuit for my router and I am considering a spindle upgrade, but I am curious how the configuration matches the math.

Yes. The VFD (Variable Frequency Drive) has a large set of parameters that can be modified. This is typically called "programming" the VFD. The parameters can be accessed using the front control panel of the VFD. Since the VFD is the mechanism that control the allowable current draw from the spindle, there is a parameter that assigns the motor rated current; however, it is probably better to match the rated current of the motor and "up" the circuit breaker current instead. If the current limit is set too low, then there is a possibility that the spindle will cause a current overload error on the VFD and cause the spindle to stop.

When wiring line voltage to the VFD your diagram shows one line of 240 going to the R terminal and a neutral going to the T terminal. My electrician thinks this may be incorrect and he believes that one leg of 120 should run to the R terminal and the other leg of 120 to either S or T. Is this correct and if so should the second leg/pole be run to S or T? Thank you

Always defer to the advice of a professional electrician. If your professional electrician believes the wiring of the VFD is incorrect as per our recommendations, always use the advice of the professional electrician.

what are the different (feed, travel,rotation) speed to use with planet cnc and a 5x10 greenbull to cut mdf please?

The feeds and speeds for cutting MDF will depend on the end mill that you are using and at the depth you are cutting. The feedrates below are based on 18,00 rpm and using a spindle. Routers will not be able to handle these feedrates. Our Onsrud end mills will cut MDF at 3/4" depth per pass at around 300 ipm using the compression end mill. A standard Onsrud single flute will cut MDF at 3/4" depth at 120-140 ipm. A general purpose 2 flute end mill at 3/4" depth can cut at around 80 ipm from our experience.

THERE�S A CELLULAR PHONE ANTENNA ON THE ROOF OF BUILDING RIGHT OPPOSITE MY WINDOW, LEVEL ABOUT TEN METERS ABOVE HEAD. AM I LIKELY TO BE IN RADIUS RADIATION?

You will have to contact the cell phone company that operates that particular antenna to obtain the radiation pattern (or emission pattern) of that particular type of antenna. Different models of antennae have different emission patterns to provide coverage of different size and shape geographical areas. For example, many of the antennae are directional, only broadcasting in the forward direction. Most emit very little radiation in the upward and downward directions, although the vertical extent of the beam can be quite different for different antennas. Some are strongly focussed on the horizon, others provide better coverage of nearby areas. Many antennae only broadcasting into a defined geometrical sector of the horizion, often 120 degrees so that three sets of antennae are required to cover the entire horizon. Therefore, to find the type of radiation pattern broadcast by any particular antenna will require local information from the equipment operator. Gary Zeman, ScD

So I had my electrician hook it up as per your recommendations and nothing happens. Nothing lights up on the screen and nothing turns on. I have verified that the vfd that I was supplied is for single phase power and I have single phase power at my shop. It is a 220v vfd and I am supplying it with 220v. What do I do now? Is this vfd a bad one and do I need a new one?

Was this VFD purchased from buildyourcnc.com and if so, what is the model number. If not, please provide the model number and we will attempt to determine the issue. Also, is this question related to a previous question you asked earlier? If so, please respond to that question with this new information. Many thanks. Additional Information: Yes it was purchased through your website, here is the number is YL600-2S-2K20 Additional Information: Ok great. I will look into it. Is this related to the R S T and L1 L2 question that was recently asked? Additional Information: No Additional Information: It started with that but then once it was wired up it changed to this. Additional Information: Ok. Thanks. Please explain how you have the VFD wired to the 220v outlet. Additional Information: I have traced the black wire clear from the panel to the R terminal and the white wire to the T terminal and the ground to the E terminal. I have even used a multimeter on the terminals in the VFD while the wires are connected and the power is on, and I get 240V across the R and T terminals and 120 from R to Ground and from T to Ground. Additional Information: I still have not seen a response to my previous additional information. It has now been 5 days since then and I still have a non-functioning VFD, what should I do? Additional Information: My apologies. I didn�t see your latest wiring clarification response. Please connect the white (neutral) wire to the �S� terminal. Additional Information: So, i wired it up and now it does in fact power up. However, now it just gives me an ERR 02 code. What does that mean? the only manual that came with the VFD is all in Chinese. Do you have a book in english? Or a list of error codes? Additional Information: I have not seen a response to my previous comment. It has been a while since i have heard from you. What do i do next? Additional Information: Sorry about that. The Er 02 code in my manual says that there is an over-current at constant speed, over-current at deceleration or over-crrent at stop. The recommended actions in the manual says: 1. Check whether the motor has got short circuit and whether the insulation of the output wires is good. 2. Check whether the motor is blocked and whether there is a sudden change of mechanical load. 3. Check whether there is a sudden change in he power supply voltage. 4. Check whether the insulation of the output wires is good and whether the motor has got a short circuit. 5. Extend the ramp down time. 6. Replace it with an inverter (VFD) of larger capacity 7. DE braking is too high. Decrease DC braking (this is only if you have a braking resistor connected). 8. The inverter has failure. Please send it to the factory to repair. What I have done in the office is to check the resistance between the motor coils. The motor coils should have the same amount of wire winding on each coil. If there is a short circuit in this coil, the the resistance should be lower since there is less wire to travel. You can use a multimeter to check between pin 1 and 2, 1 and 3 and 2 and 3. The resistance should be generally the same. Additional Information: I worked threw all the other problems. the controller is now displaying Err 10. WHat does that mean. Can you provide a complete list of error codes. Or documentation to support this device you sold to me. id like to be able to integrate this thing into my growing business. i have been pretty unhappy so far with the lack of support. If you have any documentation, can you please send it to me. i cant be the only one having issues. Or even asking for help with these VFDs.

Regarding the Combo #1 scratch build plans. I received the plans, thanks. The closest MDF in Australia is 18mm thick or close to 45/64". We do have a 19mm stable CD structural Radiata Pine plywood close to 3/4. 3/4 is 19.050mm. Which one do you think - 19mm plywood or 18mm MDF? see http://www.bunnings.com.au/plywood-2400-x-1200mm-19mm-structural-cd-plywood_p0340167 Mike

Sticking to the correct width of recommended 3/4"(19.05mm) MDF, so using the 19mm CD structural radiata pine plywood will be the best choice, the density will be the major aspect to look into when buying the material.

I need to correct myself, I meant to say a 1200oz. motor and driver, and 600oz. motor and driver. Thanks, Blake Augustine

Yes, we can source 1200 oz-in motors. When do you need the motors? We already have 651 oz-in motors here: http://www.buildyourcnc.com/item/electronicsAndMotors-nema34-651ozin and the matching driver for the 651 oz-in can be found here: http://www.buildyourcnc.com/Item/electronicsAndMotors-stepper-driver-6!0a

I have a home built CNC running Mach 3. I have power to all the motors and the breakout board but no movement when running g-code. I cannot even manually move the motors with the arrow keys or page up and down. It also has an integrated 120v receptacle showing an open ground. I don't know if all this is related.

The fact that you cannot move the motors with the keyboard serves as a clue to a couple possibilities. - The software may not be communicating with parallel port. (One possibility may be that your step pins are not low active, or vice versa depending on your drivers). - You may not be in the correct tab of Mach3. Make sure you are in the Program Run tab. - The jog on/off button on the program run screen may not be lit (invoked). This address below shows the complete troubleshooting for this type of situation. It will show how to test each pin at the parallel port at the back of the computer and everything else associated with correctly wiring the electronics. https://buildyourcnc.com/CNCElectronicsandWiring.aspx Additional Information: 6 axis robot with Mach3 Card 6 Axis Motion Controller

I am converting a 12x36 lathe over to CNC, I am interested in a 2 axis kit. I would love one stepper motor to be no smaller than 1200oz. , and another at 6000z. Is this something that you could offer? I have two other cnc machines but this is my first converstion on my own.

We may be able to source those motors. Curious, the 6000 oz-in motor is pretty big. Do you mind explaining the application of the CNC machine and the structure that would require the large motor? Additional Information: The largest motors we can offer is 3900 oz-in without any mechanical help. 6000 oz-in can be resolved by mechanical means as an alternative.

Do you have data sheets available for the Adjustable Rotary Limit Switch and E-Stop (Emergency Stop) Button - 120v-10A/240v-6A?

If the products have documents available, they are generally found on the product page itself, somewhere in the description or under the instructions.

Can you provide additional dimensional or CAD data for the 20 mm linear ball bearing block and matching guide rail (overall size, mouting hole locations, etc)?

For our 20mm linear ball bearing block dimensions: L: 1.9795"/ 50.2793mm W: 1.9055"/ 48.3997mm H: 1.4810"/ 37.6174mm The mounting holes will be 1.3500" apart from each other. The 20 mm guide rail (as sold), dimensions: L: 11"/ 279.4mm W: 1.7825"/ 45.2755mm H: 1.4655"/ 37.2237mm Mounting holes will be in the center of the 11" piece and be 5.9120"/ 150.1648mm apart with around 2.5"/ 63.5mm of rail on each side.
