Using the PoKeys57CNC how to you connect two motors to the Y axis and how is Mach 4 configured for this?

The dip switch settings on the drivers have a table on the top of the driver itself. To determine the size of the motor and driver compatibility, you first need to associate the motor to the correct driver (i.e. if the motor requires 6 amps to deliver the rated torque, you will need a driver that can allow for a 6 amp draw). Second, if the motor is rated within the amp specs of the driver, then you need to look at the motor datasheet (located on the product page of each motor) and look at the amp rating related to the wiring scheme you selected (most likely bipolar parallel). Se the dip switches to select an amp that matches this rating found in the datasheet. Remember that the dip switch is ON if UP and OFF if DOWN. On = 1 and off = 0.

Can you guys make a video showing how to adjust the white pin combinations on the redleaf drivers, in relation to the various combinations needed for the different size stepper motors?

Does the machine move smoothly when using the keyboard to jog the machine?

Additional Information:
Sorry it took so long to respond. Yes the table moves very smoothly using the keyboard. I try to reinstall of the drivers but it still moves very jerky with the MPG, sometimes moving back-and-forth.

Hi I recently replaced my parallel port breakout bored with a USB breakout board, Motors Earl working properly but my wireless MPG is not working properly, it is jerky when to try to move across the table, is there a setting that I missed?

The lead screw must be held in position axially. In other words, you don't want your lead screw to move back and forth at all. This is the only way the coupling hub that is attached to the end of the lead screw could be moving away from its coupling assembly. Depending on the lead screw that you are using, the combination of bearings and collars/nut keep the lead screw in place.

I am almost done with the book build Cnc machine, but when I run the motors from mach 3, the 1/2" coupling comes out of the middle spider (the joiner which connects 1/4 and 1/2" coupling. How do I prevent this?

You will need to use the datasheets or instructions on the product page of the actual motor you have. For instance, if you have the 425 oz-in motors, you can go here: https://www.buildyourcnc.com/item/electronicsAndMotors-nema24-425ozin

Click on the link for the datasheet, or look in the instruction steps and you will find a wiring diagram. If the datasheet gives you an option for bipolar parallel connection scheme, use that one, otherwise, there is probably only one diagram, so you will need to use that one.

delivered Stepper motors do not have the same colored wires as book/videos. What wires to to connect to what?

This sounds like it could be a loose wire, or poor connection with the motor wires. Make sure all wires that are to be connected to each other are soldered and use a lineman's splice when putting the wires together. Also, make sure that the wires going into the driver is securely fastened.

If this is an issue where the motors have run well for a long time then just started to show this performance issue, then make sure that there are no wire ties or other binding method that is chaffing the wires. This would make the motors run oddly at certain travel positions where the chafing has caused a short with the wires.

If this is an issue where you don't have the motor plugged in at all and are just trying to turn it by hand and this phenomenon is occuring, then make sure all of the wires are not touching each other. When wires are touching each other and you are trying to spin the shaft by hand, the motor will feed current back into the motor making it difficult to turn.

stepper motor runs smooth then rough for a moment then smooth, etc. Does this at all steps, and connected motors.

We apologize for the confusion, however in the very first video that is regarding the assembly, is of the torsion box. We do not included that in any greenBull kit, as we use too sell it individually! However due to high consumption of materials and high cost(both in shipping and for the kit itself) we have removed it from our inventory and no longer sell it.

This video can be skipped, however if you plan on making a DIY torsion box, this video will be helpful in your build!

The torsion box is not needed, as the frame itself will be more than sufficient in keeping the machine from flexing or vibrating.

I ordered the GreenBull 5' x 10' kit. The first video for assembly shows that I should have 5 large boards that attach to the table, but I don't have those boards. Is that something I need to build or were they not shipped?

You can use our shopping cart to determine the shipping. Add the machine and the parts you want to purchase, enter your shipping address and click on the Calculate Shipping Button to get a price for shipping. The shipping charges are determined directly from the carriers at the time of pressing that button.

Connecting the limit switches on the redLeaf use the input pins on the parallel breakout board. Here is a link to the wiring diagram for that parallel breakout board.

https://buildyourcnc.com/item/electronicsAndMotors-parallel-breakout-relay#prettyPhoto/2/

The connection is simple. Just create a circuit from ground to the pin. When the pin is engaged, the circuit is closed (using normally open on the switch). Use mach3's autoset to automatically set the pin for the limit or home setting.

Do you guys have any videos showing how to connect limit switches to a redleaf? If not, could you please make one? I looked at the diagrams on the limit switch page but I don't understand them.

The driver only receives control inputs and outputs current to turn the motor; therefore it does not really know or care what it is moving. The difference in rotary motion and linear depends on the software (machine control) for the input, and for what the motor is hooked to for the output. For example, to convert the motors original rotary motion to linear motion one might use a lead screw, a rack and pinion, etc. For rotary motion, one might connect directly to the motor shaft, use a gear box, etc. The software must account for this and issue the proper control signals, since all the motor ever does is turn a specified amount.

in the 3 axis combo setup, how do you tell the driver if its a rotary axis like a rotary table, or a linear axis like z.

The pictures of the table on the blackFoot v4.3 CNC machine page uses 2/4 studs, a torsion box, and a final top 3/4" layer.

The torsion box and the top bed layer lays on a frame constructed by 2x4 framing studs angled to resist twisting and for greater rigidity. the joints are simply connected with long screws and you can also use framing plates/ties. The torsion box is constructed of 3/4" MOD stock and has a ribbing pattern spaced around 8 inches apart. The design is similar to this: https://www.buildyourcnc.com/ModularTorsionBoxTable.aspx

The top later is simply multiple sheets of MOD 3/4" thick to conform to the required final measurement.

The table top pictured with the blackFoot 4'x8' v4.3 CNC Machine Kit looks nice. I'd like to build one just like it. How thick is it? If it was made from multiple sheets, how did you make the butt joints?

Yes, we offer a CNC electronics assembled package called the redFly, redLead and redSprout. If you already have a computer, I would recommend the redFly. You would still need to add connectors to the ends of your motor cable.

Their is no synchronization, between the software and the vacuum, besides the way that it is reading through the relay(on/off method).

The vacuum pump is controlled by a circuit that has a pressure sensor, not included, (similar circuits used in industrial applications carry a very high price due to their specialization. This circuit keeps a range of suction in the tank at all times so the picking can be at its best performance. The range of suction is controlled by two potentiometers (components that can be adjusted like a dial on a stereo) to maintain a high and low vacuum and only run the vacuum when the tank needs to be . This vacuum is shown in inches of mercury. The higher the inches of mercury (Hg), the higher the vacuum.

Did you connect the USB connector to the breakout board?

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

Click the link to respond:
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.

To move two stepper motors simultaneously with the same signal, simply wire the two stepper motor drivers to the same interface board signal terminals (CP and CW).

Click the link to respond:
I have my motors wired like the wiring diagram I have two motors on Y axis how do I wire the second motor

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.
