Are the kits provided with printed instructions or a hi-res version of whats online?

It is not recommended to drive two stepping (stepper) motors with a single driver. The driver will need to output the sum of the current that is rated for both motors. The best way to drive two motors on the same axis, or if you need the motors to spin in a synchronous fashion, then have each motor connected to their own driver and connect the signal wires from the drivers to the same signal step and direction pin on the breakout/interface board.

You can change the direction of a stepper motor's rotation by swapping the A and B coils where the stepper motor is connected to the stepper driver. This may not work with every stepper motor and driver combination.

To do this:
- Turn off all power to the stepper drivers. If this is not done, you will damage the stepper driver.
- Wait at least 1 minute for the power to dissipate from the drivers and power supply.
- Once power is off, remove the wires from the A+ and A- and insert these wires into the B+ and B- respectively. Then insert the wires that were in the B+ and B- into the A+ and A- respectively.

Using your NEMA 24 stepping motor with microstepping, can I get a speed range from 3 RPM to 600 RPM ?

What mechanical drive system are you using? If your mechanical drive system connected to the stepper motor causes the motor to spin too fast, then you will be reaching the torque limit of the motor under the load of your axis.

I have a KL23H2100-30-4B motor with a KL-4030 driver and my motor stalls if I set the rapid above 180 imp.

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 power supply that is used to power this controller must be 24VDC maximum. Any higher voltage and the controller components can be damaged. The 24VDC power supply doesn't need to be a high amp power supply. I would recommend This power supply: https://buildyourcnc.com/item/electronicsAndMotors-power-supply-24v-1a-dc

All you need is a CNC controller like the following options:

https://www.buildyourcnc.com/item/electronicsAndMotors-electronic-component-breakout-Mach3-USB-Board

This controller is easy to connect using standard wire screw terminals and works with the mach3 control software.

https://www.buildyourcnc.com/item/electronicsAndMotors-electronic-component-breakout-Mach4-mach3-USB-ethernet-Board

This controller is a little bit more difficult to connect, but is a more feature-rich controller and will work with both mach3 and mach4 CNC control software titles.

Specifically, a CNC controller connects to the computer via a USB cable and connects to the motor drivers. These controllers also connect to the limit switches, spindle/router control, air/fluid/mist control, etc.

The spindle does not come with a manual, however the inverter should come with a manual booklet in the box. The wiring diagram and PD settings for the inverter and spindle (https://www.buildyourcnc.com/item/spindle-inverter-2!2kw-spindle-novfd) can be view together on the spindle page, also you can use a local hardware store extension cord (orange) to connect/wire from your outlet(220V) to your inverter and spindle accordingly from the diagram.

Additional Information:
I also received a spindle and inverter without a manual. While the diagrams on the product page were sufficient to get the unit running, there is no documentation anywhere to be found concerning the terminal block that is used for external control. What does one have to do to get a hold of the manual that was supposed to come with the inverter? Manuals for the 220VAC model are plentiful online; however, manuals for the 110VAC model are non-existent.

I need wiring instructions for the breakout board you sent yesterday. It is not like the one in the videos and I don't know where to connect the 5V. No data sheet or anything.

To connect the stepper motor drivers to the Mach3 USB interface card, you will need to follow the wiring diagram here: https://www.buildyourcnc.com/Documents/Electric%20Wiring%20Diagram.pdf
which can be found here: https://www.buildyourcnc.com/item/electronicsAndMotors-electronic-component-breakout-Mach3-USB-Board along with all of the other manuals associated with that interface card.

Please note that the DC+ and DC- on that wiring diagram (power supply to thye stepper motor drivers) is not correct. The DC- is connected to GND on the drivers and the DC+ is connected to VCC on the drivers. Typically, the DC+ on the power supply is labeled V+ and the DC- is labeled either COM or V-.

If you are having any issues with the wiring, please let me know and I will elaborate. Thanks.

Additional Information:
Are you able to install a newer version of Mach3? If you are worried that your configuration will be lost, you can save the configuration by copying all of the XML files from the Mach folder. The XML files contain all of the settings that you applied in Mach3. Just in case the XML files are not compatible with the new version, make sure not to erase the current Mach3 that you have on the machine.

The eyebolts are used in the squaring of the machine. I would use a standard carpenters square and first run the end mill along the edge of the square to first make it parallel with the long axis. Then run the end mill along the other edge with the short axis and adjust the eye bolts and chain according to the angle that the machine is out of square.
