I purchased the 3 Axis Heavy Gantry Electronics /w Pokeys57CNC controller and the motors supplied only have 4 wires coming out of them (R,G,B,Blk). Your wiring video shows wiring 8 cables. do you have a video showing how to wire the 4 wire version?

Since the pump will use a standard 12v power supply, you will have two wires. One of those wires will be connected from the power supply to the pump. The other wire will be connected to the power supply and the pump, but cut that wire and connect one side of it in the P terminal and the other end in the S or the O terminal depending on if you need the connection as NO (Normally Open) or NC (Normally Closed).

Yes, absolutely. If you need two motors for a single axis, you will want to use the same terminals for pulse and direction from the breakout board.

More specifically, you will wire the step/pulse pin to both drivers, and the direction pin to both drivers. If the motors need to turn in different directions, simply swap the A and B coil connections on one of the motors.

i have checked the cnc machine for any flex and there is none but i still cannot cut circles they end up square.have checked calibration and it is correct but if i run at 4000 mm feed all comes out correct but if i change feed to say 2000 mm it makes the part small, like in tiny.

Using your USB control board, is it possible to install and use a Z axis touch plate? If yes, what board connections would it be installed to?

You will want to connect the homing switches (which may also serve as your near limit switches) to different input terminals. It's ok to add more limit switches with the home switches, but each home should be on independent inputs. For example, connect home X and any other limit switch to IN1, connect home Y and any other limit switch to IN2, and so on. This will allow you to properly use the "ref all home" button in Mach3.

Additional Information:
In the instructions (diagram 1) you show all the home switches connected in parallel? But here you say they need to each have their own inputs. "You will want to connect the homing switches (which may also serve as your near limit switches) to different input terminals." I dont see how the second and third axis can go home if the first axis has already closed the parallel circuit unless they back off a bit until the switch opens up again before the next axis goes to home? My machine has no limit switches so I assume they are home switches.

[575] I have finally got my limit switches wired and working - thank you. Can they also used as homing switches and if so it it just a question of looping the two inputs on the board i.e. the limit and home terminals IN2 to IN3

If one or more motor is not responding, please follow the troubleshooting directions below:

For parallel Bob only! Make sure both the parallel and USB are connected.

Re-check wiring, and connections for continuity (no breaks in the wires) and check for correct wiring locations from driver to BoB.
Check dip switch settings on the driver.
Check components, by swapping the motors (ex. y-axis motor to z or x-axis driver and z or x-axis motor to y-axis driver) to check if motor functions on another driver.
Depending on software check step low active (mach 3) or invert pulse (planet-cnc) for the axis which is not responding.

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.

I will check with the developer of the board and show the response on this FAQ.

Additional Information:
The response from the developer:
Are you referring to using Pin 17 for the spindle speed control? Make sure that you set the desired spindle speed in Mach4 by executing S1000 in the MDI or the G-code.

Click the link to add information to this solution:
Mach 4 is not triggering PWM pin 17 on Pokeys57CNC. I am able to get it to work through the Pokeys app but not Mach 4. I've made all of the setting changes prescribed in the manual.

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 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.

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 purchased the 4.0kw spindle and VFD a while back, and have just installed a PMDX-107 controller... do you have any examples of the wiring connections for the SL-240EE to PMDX-107?

For safety's sake I would recommend a new board because they are inexpensive compared to the electronics that they support. Alternatively, it's possible that the one dead pin is a simple fix, such as a bad connection or solder joint; if you feel comfortable making those repairs then it could be worthwhile to check. Finally, if you are not using all the input pins, you could continue to operate the limit switch on pin 11 and hope for the best.

I have a breakout board and it appears that the pin 12 connection has failed: when i move my limit switches to pin 11 they work; they don't work on pin 12. Do i need a new breakout board?

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.

[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

Most motherboard do contain parallel ports, but the port connector may not be at the back (in the section where external connectors will be connected). Instead, the motherboard may contain an LPT ribbon connector on the actual face of the motherboard (usually along one of the edges). You will need a ribbon connector to a DB25 female connector.

If your motherboard does not contain an LPT header on the motherboard, you can purchase a parallel printer adapter that plugs into one of the PCI slots. The price of the adapter is very inexpensive and sometimes is actually less costly than the actual ribbon connector.

As I am building my 20" x 24" laser engraver cutter, I notice that there is no parallel port on the onboard computer and I have the parallel breakout board any answers?

For our parallel breakout board (https://www.buildyourcnc.com/item/electronicsAndMotors-parallel-breakout-relay#prettyPhoto/2/) the schematic will show the connections going from the BB to the drivers. The parallel breakout board uses the 25 pin parallel connection to communicate from the computer to drivers, and the USB is used to power the main-board itself, supplying 5V.
