WAS WONDERING IF YOU COULD TELL ME WHETHER OR NOT SHIP ANY OF YOUR KIT PRODUCTS TO THE UK?

There are two things to consider when using two stepping motors on a single axis. Since you want both motors to spin at the same rate and possibly in the same direction, you need to connect both motor drivers to the same breakout board pins. For example, if you want two motors on the x-axis and the x-axis pins on the breakout board are #2 for step and #3 for direction, the #2 will connect to the step (cp) terminal on each driver and the #3 will connect to the dir (cw) terminal on each driver.

However, if the motors will be opposing (one motor will need to spin in the other direction), you will need to consider either flipping the rack on one side, or adding a circuit to invert the direction (#3) signal going to that driver.

I'm planning a rack and pinion style gantry, and need clarification on how to slave a second stepper to the Y (or X). Can you direct me to that information for your products?

Yes, to build a computer controlled table saw fence, you can try the following:

Assuming that the fence can already move, add a motor on both sides coupled to either lead screw or chain mechanics. Lead screw would be the best solution. The lead screw nuts would be mounted on the fence aligned with the motor shafts at the front and back of the fence.

I would recommend the 425 oz-in stepper motors and 3.0Amp drivers for each motor. You will need a power supply rated for 24 volts. There is no need for a higher volt power supply. Interface the drivers to the computer using a USB interface, or a parallel breakout board.

Stepping motors: https://buildyourcnc.com/category/nema
Drivers: https://buildyourcnc.com/category/driver
CNC Motion Interfaces: https://buildyourcnc.com/category/breakout

Measure the length of travel and get lead screw twice as long since you will need lead screw on both sides. Add a bit more length for space that will be needed for the mounting. Plan as much as you can before purchasing.

My apologies for not getting back to you. We always answer the phones during business hours, so I would try that first. Our emails on Monday generally is stacked up as we are closed during the weekend. We can try your g-code here. Please send the g-code to the techsupport@buildyourcnc.com email address and we will test the code to see if it works.

By the way, do you get movement on the planet-cnc UI screen?

Additional Information:
The program starts and runs normal. I have all the correct movement on the mill and the UI screen. Then one of two things happens. It either stops and resets all axis to zero in the middle of the part or it freezes in the middle of the part. When it freezes, it is not moving on the cnc or the UI screen. Sometimes after a freeze it will come up with an 'IO timeout error', but the only way to clear is to unplug USB and start over.
I will send my settings and g-code files over tonight. Please be sure to load my settings when running the g-code. No movement of the cnc is necessary as the controller will do these issues without power to any drives and just the USB board connected, on my board at least.

I have a MK1 board that I just got running and I am having issues. Do you have an MK1 board at your shop that I can send you my G-Code to run? The freexing/zeroing in the middle of the program issue happens even with no step drives attached to the board.

The USB interface only works with momentary switches unfortunately. If you have extensive knowledge of digital electronics, you can apply a receiver that uses a microcontroller and a transmitter with another microcontroller that produces the pulsing signal with the controls that you need.

HOW DO YOU CALCULATE THE ENERGY OF PHOTONEUTRONS PRODUCED THROUGH INTERACTION WITH 7.5 MEV BREMSSTRAHLUNG FROM A LINAC? TARGET GENERAL COMMERCIAL PRODUCTS IN TRUCKS.

Feedback and positioning:

- Open-loop is where the computer does not have feedback, but it has the current position as per the number of pulses it has sent to the stepper motors. As long as the stepper motors are tuned so that there is a safety factor, then your machine will always be at the correct position. This scenario is common and typical for CNC machines

- Closed-loop is where the computer receives feedback from the motors and is common on very high end CNC machines. The computer sends the pulses, or signal for the motors to attempt to achieve a particular position. The servo motors will use a PID (Proportional Integral Derivative) to continue to achieve a particular position where the driver/computer will tell the motor to go back and forth (getting better as it goes) for the position. This back and forth (the PID in action) is usually imperceptible.

I forget the term for it, but are the encoders "absolute" in regards to their positioning? So if for some reason a cut is interrupted the machine can regain its position?

We accept many forms of payment, but online, we accept major credit cards (Discover, Visa, MasterCard and American Express) in addition to checking out with Paypal.

I am in Houston. I will use this to make cabinets. Do you have a location I could see one in use cutting similar products?

Only our greenBull CNC machines will be able to use the long Z-axis, due to structural construction of the greenBull over the blackFoot.
The height from the table top to the bottom of the gantry is: 4.25"

Both the maximum cutting height and diameter, will be dependent on the specific end mill/router bit you plan on using, since they can vary in length.
The maximum cutting height (useful to engrave or cut material)is: with spoil-board 3.875", without a spoil-board is 4.625"
The maximum diameter will (estimated) is: 3"

Specifically dealing with our greenBull long Z-axis CNC machines, depending on how you specifically design the table you can have more cutting height and a larger diameter clearance. If you only create a frame for the machine with a hollow center(adjustable midsection), allowing you to have a greater clearance.
