Current Solution

Are you referring to the 425 oz-in motor? How many motors and drivers have you connected? If you have connected more than one, are they all sounding the same?

Additional Information:
it's the 650oz motor. but I think I've got the problem solved. The motor tuning was way out of whack.. I hooked up the smaller 425oz motors and they were ALSO acting funny so I knew it was not them. Software.

I'm still trying to find out what the best speeds are, so there is still some stutter and skipping. thanks for the quick response though, much appreciated.

Additional Information:
You will also want to look at your microstepping. Consider determining your expected mechanical steps per inch and desired jog speed (ipm) and you should have fewer issues. Use the formula: (motor steps * microsteps) / (number of inches of travel in one turn). The ipm for pulley or sprockets should be in the 500-1000 ipm range and for 5 start lead screw, in the 100-200 ipm range. The acceleration can be in the range of 10-40 depending on the mechanics and inertia involved.

Additional Information:
If you ask a question here like: what steps per inch should I set my axes? You will get the standard settings for our machines.

I'm new to this and was wondering if I connected something incorrectly... I followed the schematics found on this site for wiring. I purchased the heavy gantry kit with the USB power option. All my lights come on and motor shafts resist turning but, I cannot get movement from Mach3. How do I test my equipment to see if I've damaged anything?
By USB power do you mean the USB board? or do you mean that it is powered through USB but you have the parallel breakout board?

Additional Information:
I was referring to USB Board. Thanks for responding but that issue was resolve. I noticed that Mach 3 was downloaded twice. I copied and pasted RNR file to second copy of Mach 3 and motor runs properly. Should I remove one copy of Mach3 so there is only one? Seems like that could cause confusion. Thanks

I connected the electronics (for 2 x 4 feet) that I ordered from you. But how do I check if I connected all the wiring properly. There is neither any light on motor drivers nor on breakout board. And the motor shaft also does not move before and after the power supply is given.
Did you connect the USB connector to the breakout board?

Additional Information:
YES I CONNECTED THE USB TO THE BREAKOUT BOARD

I have followed all the "CNC Electronics 1 - 9" videos and I'm using almost the exact same components (motors run and sound good) but the motors are runing very hot in just 15min with no load - have I done something wrong or do steppers run very hot?
If your motors are hot to the touch, this is normal. Current is being drawn by the motor coils as the motor moves and as the motor stays at a position. If the motor is not using the current in the coils to move (holding it's position), the energy will be translated as heat (rather than motion, sound or light). Even while moving, some of the energy will be lost as heat. Remember that energy cannot be created nor destroyed.

In the BlackTooth instruction the concluding sentence suggests connecting a wire from the right terminal of the pot to the VCC on the Laser Supply. There is no VCC on the power supply for the Laser that I can find. So, does this wire go to a different terminal on the power supply, or somewhere else where VCC exists, such as either stepper motor control?
VCC is the same as 5v. I will clarify on the instructions.

[311] I am looking to use this type of thing with a pipe for theater. Where the pipe can be lowered and it would have electrical and signal cable inside. Is this good for that or should I look at something else?
This would totally work for that application. This cable carrier is used for any object that needs to move and carries some electrical or tubing within it. This cable carrier is great for cable management where you want to make sure the wires and tubes are in a position that you set, not where the wires and tubing want to go.

[575] Can you please point me in the direction of a list of VFD Parameters for this to as intended for spindle speed control? I’m using Hunyang VFD. I’ve verified outputs/relays working as intended and PWM signal is correct at the VFD, but its still pulling speed control from the onboard pot instead of PWM signal. I’ve tried every combination of parameters I can think of but no luck.
The HY VFD has three main terminals for PWM control. These terminal inputs are:
- VI for the analog (PWM) voltage input (input at the VFD, output at the controller, i.e. the Mach3 USB controller),
- 10V output (this is an output from the VFD and an input at the controller) serves as the high voltage value for the width of the voltage,
- and ACM the ground from the controller (DCM at the controller)

In the parameters:
- PD002 should be set to 1 (one). PD002 is the source of operating frequency which is the RPM of the spindle in the Hz frequency units. 400Hz = 24000 RPM.
- PD003 specifies the frequency range for these terminals (10V, VI, and ACM) where 10V (voltage reference) is 400Hz and 0v is 0Hz, and VI adjusts the range from 0 and the voltage reverence (10V).
- PD070 selects the voltage range or current range (for use with the AI external VFD terminal as opposed to using the VI). You want to keep that parameter at the factory setting of 0 (zero) 0-10V.

Y axis on usb controller not working. The motor gets power and holds but will not turn. I tried switching the same wires, driver, and motor over to the A axis on the controller and it works fine like that. I have double, and triple checked the wiring
This sounds like a problem with the step (pulse) signal. The driver motors receive two signals from the computer via the board -- one is high or low and tells the motors which direction to turn, one is a square wave pulsed signal(quick that tells the motor to turn or a constant high signal that tells the motor to maintain its position. With an oscilliscope you can check for proper signal at the board. If you bought the board from us, please contact us to arrange a return authorization.

On the blacktooth machine wiring diagram for parallel breakout a wire goes from 6 on the BOB to TL on the laser power supply. My power supply has an"H" followed by a "L". Which is correct? I've connected to the "L" but the laser appears always on.
The digital signal portion of the CO2 laser tube power supply has various terminals for signal power, signal gnd, laser intensity and engaging the laser (turning it on or off). The TL and TH are triggers to turn the laser power on or off. These may be labeled L or H on some laser power supplies. You can use either TL/L, or TH/H to control the laser.

If you use the TL or L terminal to control the laser:
If a low signal (gnd) is present at that terminal, the laser will turn on. If a high signal (5v) is present, the laser will turn off.

If you use the TH or H terminal to control the laser:
If a high signal (5v) is present at that terminal, the laser will turn on. If a low signal (gnd) is present, the laser will turn off.

You should first test the control signal from the interface with a multimeter to make sure the laser will be controlled correctly before powering the laser power supply

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.

I AM USING USB BREAKOUT BOARD WITH PLANET-CNC SOFTWARE. WHEN ENABLE JOGGING KEYBOARD X AXIS STARTS TO MOVE BY ITSELF (WHETHER CONNECTED OF NOT). PRESS STOP - IT STOPS FOR A MOMENT AND THEN AGAIN. WHAT COULD THAT BE? TRIED REINSTALL SOFTWARE DID NOT HELP.
It seems to be getting some kind of interference or a short within the wiring or communication, try jogging the motors in the software without anything wired to the board. Then add one motor at a time to see if there is a short within your wiring or a faulty driver/motor.
If the USB breakout board continues to move the x-axis with no motors or driver wired to it, please email customerservice@buildyourcnc.com for a replacement or further troubleshooting.

Hello, I am trying to configure Home and Limit switches using the Pokeyes57cnc and NC switches. I am confused on the procedure of setting this up. wiring to the board and setting up in Mach4. Can you direct me to a tutorial or offer some suggestions? Thanks Dale
NC mechanical switch configuration is supported. You can download the manual from this page (Mach4 plugin and manuals):
https://buildyourcnc.com/item/electronicsAndMotors-electronic-component-breakout-Mach4-mach3-USB-ethernet-Board

The pokeys57CNC controller has input terminals and pins for limit switches on each of the 8 axes. There are three separate inputs per axis, two for the actual limits of that axis, and one for the home position.

Connect each switch between the GND terminal and its respective axis limit terminal/pin. For instance, the limit switch will typically have three leads, COM, NC, and NO. In an NC configuration, the NC connects to the terminal/pin, say, Axis 1 lim +, and the COM connects to the GND terminal.

In Mach4, in the new device wizard, make sure to specify the correct option on the home and limit switches that matches the machine configuration.

Additional Information:
can you use one switch per axis for home only?

I have NEMA 34 motors for a GreenBull 6x12. After 2 weeks of use, my Y axis motor has developed play in the front but not rear of the motor. Is this a motor defect or has something come loose somewhere? Thanks,
If there is play within the motor itself, then that motor may be defective. Call us to provide us more detail on this issue.

My Z-axis seems to be reversed on a fully assembled machine... I've tried reversing it in the config settings on Mach 3, but to no avail. What do I need to do? IS this a wiring issue that was not done correctly at the factory?
If your Z axis is moving in the opposite direction, go into Mach3, click on config, ports & pins, then click on the motor outputs tab. You will see the axes labeled on the left and the parameters labeled on the top of this dialog box. Toggle the dir low active for the z-axis.

Additional Information:
What if I'm having the same issue on a different axis?

Additional Information:
You can follow the same procedure as with the z-axis. When you get to the motors outputs tab, toggle the dir low active checkbox for the axis that you would like to change.

If you are using another control program, let me know and I will add the recommended action here.

[788] Thanks for the oportunity to ask, I am building a cnc and using npn closed sensors could you help me with the conection of these, do i still connect them in series if i use more than two in each axis. Also you mention that a stop switch should be connected grd and input to the controller would that be done after the 24v power supply. Thanks r
If the sensors are NC (normally closed) you can wire them in series. If the sensors are NO (Normally Open) you can still wire them to the same input, but the wiring needs to be in parallel (like a ladder). I have more information on the following video:

You should have no problem connecting the Pokeys57CNC controller to the drivers of your machine as long as the drivers have step (Pulse or PUL) and direction (DIR) terminals. You will need the cable pack that is sold separately so you can connect the headers/connectors of the pokeys57cnc controller to the drivers using ribbon cables.

I show this process in great detail on this page:
