When wiring the limit switches to our BoB(breakout board), depending in the older model or our revised version (https://www.buildyourcnc.com/item/electronicsAndMotors-parallel-breakout-relay#prettyPhoto/0/), the older version will need the COM (limit switch) connected to 5V and the NO/NC to your input pin, but with our newer version you will use GND(ground instead of 5V) to common and the same for NO/NC but the setup in the mach3/confi/ports&pins/ is still the same.

Here is a tutorial where you can see how to set up the limit switches correctly (with our older parallel BoB): Part 1:(

I am attempting to set up limit switches on the 5 axis parallel breakout board that came with my BlackFoot kit. The output pins are driving the motors perfectly, but I can't figure out the input pins. With one lead in the 5V pin and one lead testing the input pins, my multimeter reads 0V for all of the input pins. Shouldn't those circuits be +5V? Where am I going wrong?

WE don't have an actual file that contains the instructions for the machines as they are a part of a larger database file that is queried during the product page's rendering in the browser. The best option would be to print the webpage on a printer and use that as notes.

I know this will not provide larger images, but you could use the paper version to write your notes while assembling the machine using the larger images on the website.

On the blackFoot 4'x8' CNC machine do you have the instructions under one file that I can download, I want to print them out and make notes as I am building the machine.

Absolutely, I can answer this type of question and anything other questions you may have with your new-to-you CNC router.

[789] Can you help me with selecting a power supply ( and a few other components ) for the stepper motors that came with a homemade CNC Router I just purchased.

You will also need to check if the mach3 configuration and the wiring. Since you tested the connection from the motors to the drivers, the connection from the computer to the interface may still be the issue. It could also be the connection from the interface to the drivers, but we test all of these units going out, so I don't believe that would be the problem.

If you have a redfly that uses a parallel cable, you may need to check to make sure the parallel cable is functioning properly, and also, make sure that the interface is also powered using a usb cable.

If you have a usb interface (the terminals will be labeled XD, XP and so on), then there may be a wire not seated correctly in a terminal.

I plug in my redFly for the first time and after configuring Mach3 and rechecked my settings axes Y and Z are working well, but X is not working, just for testing I plugged in each motor to the Y and Z and they work fine, but no motor works when plug into the X axes of the redFly, also one of the NEMA 24 425 Oz motors dose not turn just jitters.

This would totally work for that application. This cable carrier is used for any object that needs to move and carries some electrical or tubing within it. This cable carrier is great for cable management where you want to make sure the wires and tubes are in a position that you set, not where the wires and tubing want to go.

[311] I am looking to use this type of thing with a pipe for theater. Where the pipe can be lowered and it would have electrical and signal cable inside. Is this good for that or should I look at something else?

Are you trying to use the MPG (tab), or the keyboard for jogging the motors? You mention 0,0,0, are you trying to home the machine with the "ref all home"?

If you cannot move the motors with the keyboard, check if the jog is enabled.

We are currently working on a relay board that will connect to USB breakout board, and the router/spindle for both the on/off function. Unfortunately we still do not have it completed or ready to be placed on our website, but it is in the final stages of testing. Please check back regularly for updated stock!

The cutting area is 20" x 40" for the book machine. This area is determined by the 2'x4' sheets that make up the bed of the machine. You can increase this area if you use larger sheets and adjust the gantry width by the same difference of the width of the sheets.

You can also use the plans from Woodsmith magazine to build a larger machine.

CamBam specifically creates the g-code (machining operations) instructions to be loaded into Mach3. Make sure in your CamBam g-code file parameters, you are using the Mach3 post processor. If you have already done this, let me know. If you are not sure how to do this, let me know.

It is likely that if your Spindle's collet is ER11 specification than other size ER11 collets will work with your spindle.

I bought a 1.5kw spindle that came with the ER11 6mm collet. I found collets for 1/4" and 1/2" but will these work with my existing nut? I see there is a nut for sale but it says its just for Bosh and Porter Cable etc.

Yes, you can connect a THC, Torch Height Controller, with the Mach3 USB controller. The THC uses the inputs to determine if the z axis needs to move up or down according to the arc of the plasma torch. The THC connects its outputs to the inputs of the controller so the controller will be informed of the states of the plasma torch.

I am interested in using the Mach3 USB interface board. I was wondering if there was a way to run a torch height controller with this board for use with a plasma cutter, and if so do you know of any THCs that will work. Thank you.

Yes, servo motors can be mounted on this machine. If the mounting dimensions are different than NEMA 23 or NEMA 34, then all you need to do is keep the center of the motorshaft with the center of the bearing location and locate the mounting holes for he servo you wish to use. Most industrial servos used for these machines share the same mounting dimensions and NEMA specifications.

Yes, we can make a redLeaf system that has all 6A drivers for use with the 651 oz-in motors. We can also wire the electronics in a way that two of the drivers will use the pins of the same axis so that axis will drive two drivers and motors.
