### Question #: 904

Question: For our cnc we're searching for an air cooled spindle with 2.2 kw. On this page we've only found water cooled ones. Is it possible to get an air cooled spindle from you or do you have special reasons for don't selling them?

Current Solution

We like the water cooled spindles since they don't blow the chips around the shop. The air cooled spindles have a force of air that partly makes the vacuum and dust shoe non effective, unless we design a diverter, which limits the cooling effect for the spindle.

• I HAVE A 2.2KW WATER COOLED SPINDLE WITH YL620-H VFD. THE VFD USES P#-## PROGRAM FORMAT. BELIEVE ALL CORRECT SETTINGS SETUP BUT WHEN TURN UNIT ON, IT SPINS AT ABOUT 200-300 RPM REGARDLESS OF WHAT FREQUENCY CHOOSE. DO YOU PARAMETERS IN THIS FORMAT FOR UNIT? THANK YOUR HELP. HUIBERT MEES

You will need to look for the parameter that controls the run frequency. The frequency can be controlled bu the panel, external terminals, or the RS485 TX/RX terminals (UART protocol). You will want to change that parameter so it uses the panel. If you are referring to the maximum panel dial frequency is only allowing 200-300 rpm, then look for the parameters to control the frequency.

For 200 RPM:
Hz = 200/60 = 3.33 Hz

For 300 RPM:
Hz = 300/60 = 5 Hz

Conversion to RPM:
If you ever find yourself yearning to reverse-engineer the process, the formula is as follows:

RPM = Hz × 60

Look for values that match somewhere between 3 and 5 in your frequency parameters and replace them with 400 to give you 24,000 RPM max.

• It is possible to control externally the 1.5kW Inverter (VFD) (220 Volt) with PWM so i can control the spindle rotation? Do you have the documentation? Thank you

Our spindle VFD's, have a multitude of different connectors that can be used for different operations. There is a manual that comes with each VFD, and you can refer to page 11 for different functions and descriptions.

We currently have a PWM, working with our machine, however it is connected via USB, and setup through Mach 3.
Also if you may have misplaced or lost the manual here is a link to the pdf:

• BUILDING ONE OF YOUR GREENBULL 6X LONG AND 2.2 KILOWATT SPINDLE DOES NOT FIT. SEEMS LEAD SCREW YOU SENT WITH KIT IS SHORT 42" LOOKS LIKE IT NEEDS TO BE 5 OR 6 INCH LONGER. THIS CORRECT? WHAT THE NEEDED LENGTH FOR UNIT?

The leadscrew length for the greenBull long Z-axis is 47 inches.

• I purchased a vfd and spindle from a friend, his set up is 220. I don't have 220 in my shop. My question is can I use your 110 vfd with this spindle??

Depending if the spindle can work with this specific VFD, it might be possible. However we would not like to risk you working unit, with a possible match so we would like more details on your specific model and any information available on the spindle itself.

Response
The only info on the spindle is 2.2KW 400HZ 220V. Made by Zhong Hua Jiang.

Was originally on a Delta C200 vfd. That is 220 single phase.

• 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.

• I am having trouble connecting the cambam program with my Mach3 to my 4X8 Blackfoot CNC machine. Where can I get help on this issue. Have had my machine since 2015 and have not been able to use it. Thank you

CamBam specifically creates the g-code (machining operations) instructions to be loaded into Mach3. Make sure in your CamBam g-code file parameters, you are using the Mach3 post processor. If you have already done this, let me know. If you are not sure how to do this, let me know.

• I am making my own CNC setup using all the electronics from your website and I have many questions. Please advise how to have my computer recognize the USB connection from my breakout board also I would like to use a water cooled spindle but I need to know the parts required for a 4x10 bed area used for woods and plastics

You will need PlanetCNC software for the USB breakout board and when plugging in the USB the computer should automatically recognize the board, however you can go into device manager to see if the USB terminal is working correctly.
The parallel breakout board; the USB is not a connection terminal rather than a power source, and the parallel port will be the communication terminal.
The items you will need for a water cooled spindle would be: water pump, silicon tubing(length desired by customer), a extension cord(from a hardware store(orange))(1 same gauge wire/length as extension cord).

• I have a GMT 2.2kw water cooled spindle that sounds like the bearings are going out and want to know if your spindle (https://buildyourcnc.com/Item/spindle-inverter-2!2kw-spindle-novfd) is comparable for a swap. The drive is a Delta VFD-M 220v.

Our spindle should work fine with your Delta VFD-M 220v. Spindles that match a VFD are specific to the coil windings. The bearings, shaft and other mechanical components that make up the spindle may be different, but that should not matter.

• Does the Redfly that I bought with the GreenBull in 2016 work with Mach4? Also I want to add a 4th axis and a spindle with automatic tool changer. Will this work too or do I need a new control board? I bought my CNC with a longer Z travel, so I have plenty of room for these. Thanks!

That will depend on the controller that was installed in the redFly. If the controller is a pokeys57CNC controller, you can use Mach 4 with that system.

You can add a 4th axis and an ATC (Automatic Tool Changer) with the redFly system.

• [575] Hi, I plug HY 220v spindle on the board. It work, but the is a unstable frequency on the spindle. I put shielded wires from BOB to Inverter, and from Inverter to Spindle. But the problem still there. I read that I have to put a Analogue PWM, is that true, or I have problem with my wires... Thank you

You may want to try using a ferrite core or an inductor in addition to the shielded cable. Also, make sure you are grounding the shield at both ends. Even though this is not high frequency, grounding the shield at both ends in a motor scenario may help. Also, try to reduce any parallel wire runs.

• CNC Wood Lathe project - Would like to have the guts to a 2 axis DIY lathe. Can you let me know of a possible one stop shop solution? Would like it to be at least 40" on the X axis.

There are many possible options for making a lathe. Typically, a lathe is run by a spindle at the head stock (which you can find here https://buildyourcnc.com/SpindlesAndAccessories.aspx) which will rotate the object rather than a fourth axis, however you will need to create or buy the clamp mechanism of a regular lathe to hold the object in place. You will be able to control the on/off either manually or via software, but the speed (RPM) will have to be controlled manually.
You can create a more indexed alternative to a lathe by using our rotary axis at the head stock (found here https://buildyourcnc.com/item/axes-4th). either way, the tail stock center can be found here https://buildyourcnc.com/item/axes-4th. This will give you full control of the turning via software.

You will want to use linear rails and their associated bearing blocks (found here https://buildyourcnc.com/item/mechanical-rails-HIWIN-Linear-20mm and herehttps://buildyourcnc.com/item/mechanical-rails-linear-guide-rails-20mm) to run along the length of the item being turned and you will need linear rails to be run perpendicular (towards and away) to the object being turned that would hold either the blade (for a traditional lathe) or a spindle (for the indexed version containing the rotary axis).

Where you have linear rail, you will also need lead screw (found here https://buildyourcnc.com/item/mechanical-leadscrews-lead-screw-!5-5-starts-10-tpi) to transmit motion using motors (and drivers) of your choice also with various options (found here https://buildyourcnc.com/category/nema and here https://buildyourcnc.com/category/driver). You will need 2 - Drivers (either 3.0A or 6.0A, the 6.0A driver will be for our larger motors hence you will have more torque available) and 2 - Motor's (either our Nema 24's or Nema 34's, the Nema 24 will work with our 3.0A driver while the Nema 34 will work the 6.0A)
To control these motors, you will need a parallel breakout board and Mach 3 software to control the two axes (or three with the rotary axis) found here https://buildyourcnc.com/item/electronicsAndMotors-parallel-breakout-relay and https://buildyourcnc.com/item/control-SOFTWARE-mach3.

You will need couplings to couple the lead screws to the motor shafts (found here https://buildyourcnc.com/couplings.aspx). All of the miscellaneous hardware you need can also be found here https://buildyourcnc.com/Hardware.aspx.

• HAVE THERE BEEN ANY STUDIES OF POSSIBLE RADIATION DANGER FROM HEADSETS USED WITH HANDSETS CORDED TELEPHONES? I A TELEPHONE BATTERY-POWERED HANDSET. THIS HANDSET HAS JACK FOR HEADSET, SO YOU CAN WALK AROUND THE HOUSE AND YARD ON YOUR BELT WHILE TALK INTO HEADSET. EITHER OR HEADSET GIVING OFF RADIATION, LIKE CELLULAR PHONE? DANGEROUS AMOUNT RADIATION?

Headsets have been tested by the manufacturers and meet the current ANSI/IEEE standards for RF safety, the same standards that the Federal Communications Commission enforces under the Telecommunications Act of 1996. These standards place limits on the specific absorption rate (SAR) of radiofrequency (RF) energy in the body. Recent inflamatory articles in British press were not substantiated by testing in ISO-accredited testing facilities at Motorola. Manufacturers of cellular phones are required under FCC regulations to assure that their products meet the SAR limits on both hand-held and hands-free units. Further information may be available from the FDA or from the FCC. Ron Petersen, Lucent C.K. Chou, Motorola

• However it how do I get the software to work? PlanetCNC sent me a key that looks like it will only work with a backup control board I purchased from them?

When you plug the USB controller into the computer using a USB cable, and the planet-cnc software is running, you will be presented with a dialog box that will contain a text box for the key that you received from the planet-cnc folks.

Is there any other software that will work with your controller Mach3? Thanks for the help!
