To use the PoKeys57CNC with KUKA, you will need to make sure that the servo drives will be able to receive pulses that are generated from their 8 step/dir signals.

The PoKeys57CNC Manual states:

PoKeys57CNC is a blend between general purpose PoKeys device and motor controller. The device is targeted primarily for controlling up to 8 STEP/DIR signal driven motors (stepper motors, servo drives, etc.)

Here is a link to the Pokeys57CNC Manual:

Does the PoKeys57CNC board with MACH4 support simultaneous coordinated motion, as in controlling a 6 axis robot arm with large servo motors? I have 4 huge KUKA robots with complete control cabinets with all the servo drivers intact but the control language is so old and obsolete that it makes them pretty useless.

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.

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!

We are currently getting it completed for us to post it under the 2.5A stepper driver page. However here is the correct wiring procedure.

First: Wire the 24V power supply to the 2.5A driver, by wiring +V on the power supply to 12-24V on the driver. Next wire the COM on the power supply to Ground(GND) on the 2.5A driver. GND on the driver will also go to the GND on the USB board, for specific axis. (additional 3-4 wires connected to ground will be needed for the other axes as well).

Second: Wire the USB board to the driver(one driver per axis on the USB board):
CP on the driver will go to CP on the desired axis on the USB board.
CW on the driver will go to CW on the desired axis on the USB board.
5V will go to the VCC pin on the keyboard jog pins on the USB board (check schematic here: https://buildyourcnc.com/item/electronicsAndMotors-electronic-component-USB-Controller-Breakout#prettyPhoto/2/).
GND on the USB board to GND on the driver. (as specified in step 1).
EN is not used.

Personal Note:
I would recommend that you crimp the VCC pin to a wire which could be split for the other axes as well, each driver will need 5V.

Third: Wire the stepper motor to the driver, (using either the Nema 23 100-oz or the Nema 17 62-oz stepper motors, the wiring will be the same. For the Nema 23 the yellow and white is not connected.)
Black to A1
Green to A2
Red to B1
Blue to B2

Fourth: Repeat steps 1-3 for each driver/motor per axis.

Mention: Remember that GND on the driver will also go to the GND on the USB board for specific axis, and VCC pin on the USB board (keyboard jog) will go to 5V on all drivers for each axes as well, each driver will need 5V!

Is there a complete wiring diagram for the Medium Combo Kit with the usb board? Your USB tutorial does not cover the modular 2.5a drivers. https://buildyourcnc.com/item/electronicsAndMotors-3axis-100-elcombo

This is most likely a wiring issue. I would disconnect all of the power to the drivers and reconnect one at a time to isolate the problem.

Additional Information:
that was not helpful. I already did that way before submitting this question. there are not that many wires here and I have already rewired this a few times. I actually think its a software or interface board issue because it does work sometimes but then trips (possibly a amperage / voltage issue) I am using the interface board that has a parallel port and usb for 5V. are there different settings that I need to setup?

I'm using the big 651oz in stepper motor for X and Y and the smaller 325 for the z and X and Y keep tripping when I try to tune the motors on Mach3 but Z seems to work. I have to turn power on and off to reset....is this a wiring issue?

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.

I will send two 8mm to 1/2" couplings to you ASAP. Please send an email to customerservice@buildyourcnc.com so I can determine to whom to send the couings. Thanks.

Additional Information:
Please notice, I followed up with several emails abut this situation. In one, I corrected the motor shaft sizes to 10mm. I understand that, as a result of my emails, the original 1/4" x 1/2" couplers were sent and apparently received by someone at the wrong address. As of this time, I have received no couplers of any size and have gotten no reponses to my emails. Can you enlighten me?

Additional Information:
I looked all throughout my email and I cannot find an email from you. Please send an email to phooddaniel@gmail.com so I can determine who this is and to whom I need to send the new couplings. Thanks

I ordered two NEMA 23 steppers with 1/4" shafts, I received motors with 8mm shafts. I also ordered two 1/4" x 1/2" couplers, which I have not received. I have no problems with the motors, but I will need couplers to match the 8mm shaft to 1/2" lead screw.

Recommend first test to check a non-working axis, is to connect the current working axis(ex X-axis) to either the y/z axis to test the actual board and wiring in other axis setup. If tests failed and working (x-axis setup) does not working in the new axis location, go the Planet-CNC/File/Settings/Axes and check if your current non-working axis setup requires a inverted pulse. Check box and test again.
Next test if first fails, is to check continuity in your wires. A simple multimeter(ohm's) will work, just connect the positive and negative ends to one side of the same wire and if reading comes to 0.000, wire has continuity and if reads 0.L then there is a break in the wire and should be replaced.

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.

To home the z-axis using a plate:
- Connect the end mill using a large clamping device like an alligator clip with a wire connected to GND.

- Connect the plate (solder a wire to the plate) to one of the input pins.

- You can use the autoset to setup that pin in Mach3 simply by touching the two together once connected to the pin and GND.

Alternatively, the end mill can be connected to the pin and the plate connected to GND as long as there becomes a complete circuit when the end mill touches the plate.

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,

We currently do not have any Nema motor's with a .375"/3/8" shaft diameter. The motors in stock 100 oz, 425 oz, with a 1/4" input shaft. Our 651 oz, with a 1/2" input shaft.

Your combo kits don't specify whether they are standard NEMA motors. I need Nema 34 with a .375 shaft diameter. Which 3 axis kit work for these requirements?

If the z-axis motor changes directions when jogging, and continues even when replacing the motor! It seems as it is either a wiring problem or the driver? I would recommend changing the z-axis driver and check the wiring going form the driver to the breakout board.
If problem continues please contact us at customerservice@buildyourcnc.com

No, the 3.1 version will not support slaving the X axis. You will either need to wire the two x axis driver to the same X signal pins, or use the DDCS v4.1 which does support slaving an axis.
