If the Z-Axis is moving down when you press the page up or page down (or by moving the z-axis by another means like with an MPG, Pendant, or the built-in MPG in Mach3), then the direction signal wire is not connected correctly. The direction signal wire works by moving in one direction with a low signal (like gnd) and moving in the other direction with a high signal (like 5v). If the signal stays at one of the two signals, it will only move in the direction of the current signal state. Recommended action is to determine if the DIR- and DIR+ signal wires are connected securely and make good contact at the driver and controller sides.

To make an axis move in the opposite direction to what it is currently moving, you will need to toggle the ":direction:" active low setting for that axis. for instance, if when you press the page up button and your z-axis move down instead of up, then you need to make this change in the configuration.

To do this in Mach3:
- Click on the config option in the top menu
- Click on ports & pins
- Click on the motor outputs tab
- on the axis you wish to reverse, click on the "dir active low" to toggle the state of that parameter.

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.

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?

The Mach3 USB interface board requires 24V relays externally. There are no relays on the mach3 usb board. If you use an external relay on the mach3 usb board, the relay connects to the V+ which is 24V and the output pin is the return.

Additional Information:
I understand what you are saying. Does your relay board work with the Mach3 USB board? If not, what relay board do you suggest to work with this usb controller?

Additional Information:
Our relay board works with our parallel breakout board. An off the shelf SSR (Solid State Relay) made for 24V should work fine.

It's not the one in your picture and it's got different connections, for which there isn't a wiring diagram. The one I ordered says it is 5v, this one seems to be saying it's a 24v unit. Can you please explain what has happened? Thanks

it is possible to install 2 motors on a single axis but you will require another driver and motor, but wire it directly to the same pins on your breakout board. Also the orientation of your motor since it is opposite side of the original so getting it to move accordingly to the original motor it will need to be orientated correctly. The slight shift could be the cause of the rod not being completely flat where the set screws are suppose to tighten the sprocket to the rod, so sanding it to a flatter surface might fix the shift in directions.
Currently do not have a kit or schematic available.

My X-axis on the Blacktoe cannot run above ~40 ipm. I've checked all connections,tensions, sprocket locks, etc. All is fine. Can the 425 OZ stepping motor be replaced with a bigger motor, or could a second 425 OZ stepper be added to increase torque?

Is bottom left your zero with regard to screen position, or actual machine position (looking down at the machine)? You will want the zero of the machine to reflect that of the screen. This is to make the safest possible scenario for working with the machine and it insures that the output will match that of the screen.

User response:
I'll answer my own question. Unchecked Dir Low on "Y" text now cuts the way you see it in Mach 3. The only thing now is "Y" is plus moving from right to left. I don't think that makes much difference as long as I know that. I'm not sure what will happen if I used a file from someone else. Any opinions?

buildyourcnc response:
It is still recommended that the origin is located where you would expect it to be on the machine. It sounds like the origin is at the right. It also helps to orient the keyboard when jogging where the machine movement matches the direction of the arrow keys.

i have cnc router. when I do text I have to flip it upsidedown (in software) else it prints backwards. Bottom left is zero and x and y go plus from there. y has dir low checked x does not.

In all CNC electronics configurations, you will need the motor paired with its own driver.

If two motors/drivers are intended for a single axis and the motors need to turn at the same rate and in the same direction, then the two drivers for these motors should be connected to the same signal wires from the breakout board (step (CP) and direction (CW)) signal wires.

If the motors need to turn in opposite directions, then either one driver will need to have the direction signal inverted, or resolve the opposite direction through a change in the mechanical drive train (i.e. flip the rack on a rack and pinion configuration, or in a roller chain setup, have the chain ride along the opposite side of the drive sprocket).

How do I go about purchasing a redleaf system with 4 drivers, where the (y) and (a) driver are connected to the same signal from the breakout board? I'd also need them to rotate in opposite directions.

The redLeaf webpage contains a purchase option for an extra motor and driver. We can setup the redLeaf system uniquely so it conforms to your application (i.e. motors running in opposite directions).

I've built a machine where the y axis has (2) 425oz motors, x axis has (1) 425oz. motor, and the z axis also has (1) 425oz motor. Would it be better to purchase a redleaf system with 4 drivers? or can I just connect both y axis motors to the same driver for a total of 3 drivers?

The firmware update for the USB board is done by PlanetCNC. with your board hooked up to the computer via USB cable, log into PlanetCNC. Then, from the Machine tab on the toolbar choose firmware from the drop down and click on update.

Is there a firmware update in the last two years for your USB board? If so how do we get it and install? If not do you expect any updates? If updates are released how do we find out?

If you want speed control, it is recommended to use the RS-485 connection on the VFD and use the control program such as Mach3 to communication serially with the VFD using this RS-485 connection.

If you would rather use a controller such as the PMDX-107 to simulate the effect of a potentiometer using the Aref, Aout and Agnd and the Rev/Dir and Fwd/Run terminals to control operation and direction, you can connect those to the VFD.

PMDX-107 Aout connects to the VI (analog voltage in). This is like the wiper on a potentiometer.
PMDX-107 Agnd connects to the ACM terminal on the VFD for Analog common.
PMDX-107 COM connects to DCM terminal on the VFD for Digital common.
PMDX-107 Fwd/Run connects to the FOR terminal on the VFD for Forward.
PMDX-107 Rev/Dir connects to the REV terminal on the VFD for Reverse.

Refer to your PMDX-107 manual to correctly configure your dip switch settings and make sure to calibrate (tweak) the speed control using the trimmer next to the terminals on the PMDX-107.

I have the USB controller board and the 8825 step driver. I need a wiring diagram between the two. Specifically, what does the GND pin on the X-axis connect to? Also, what does the 5V pin on the driver connect to?

You can find a wiring diagram here:
https://buildyourcnc.com/item/electronicsAndMotors-electronic-component-USB-Controller-Breakout#prettyPhoto/2/

The CP terminal is wired to the step terminal on the 8825 step driver.
The CW terminal is wired to the direction terminal on the 8825 step driver.
The GND terminal connects to the GND on the 8825 step driver

The 5V connector on the driver simply powers the logic side of the chip and needs to connect to VCC pin on the keyboard jog.

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.

I believe I've corrected the issue. I found that their are 2 spring like tabs on the female USB port. And take a sharp point like on a compass and gentle raise those tabs a bit. This tighten up the connection, and I never received an error from losing connection.

The KL-4030 is a Keling 3.0 amp stepper motor driver. These are generally pretty robust drivers. You mentioned in the question that it worked for one hour. This sounds like it could be a contact issue with the wiring in the terminals. I would recommend that you check all of the connections. The terminals that are used in these drivers have terminals that are easily used incorrectly.

Make sure to open the terminal all the way using a small screw driver. Then insert the exposed wire into the opening and re-tighten the terminal. Make sure of a good connection by tugging on the wires.

Also, check kthe digital wires that connect from the driver to the control board.

On "our" VFDs, we advise that the R connect to black (live), T connect to white (neutral) and green to E or earth. We are not professional electricians, so we also recommend that you seek the advice of a professional electrician. Some VFDs are made to work on 3 phase power and this configuration may not work with these VFDs.

There are many ways to wire an emergency stop switch. The simplest, and arguably the most certain, way is to wire the switch into the incoming power so that throwing the switch kills all power to every part of the machine. Here is a diagram showing how a customer wired such a switch on their blackTooth laser which you could adapt to your needs. http://www.buildyourtools.com/phpBB3/viewtopic.php?f=12&t=4872

Alternatively, you could use an input pin on your USB board. The wiring would depend on whether and how you might be using limit switches (single or multiple switches; normally open or normally closed). Our website datasheet for the USB board is at https://buildyourcnc.com/item/electronicsAndMotors-electronic-component-USB-Controller-Breakout#prettyPhoto/2/ and shows how to configure the switches for each set up. If you use this method, you'd essentially wire the e-stop as a limit switch.
