Did you set them up as limit switches or home switches?

Additional Information:
Not sure where do I check that?

Additional Information:
Go to config, then ports and pins, then input signals.

Additional Information:
The limits are labeled x++, x— for example.

I'm using Mach3. I have 2 limit switches on X, 2 on Y and 1on Z for retracted/home. I can go to diagnostics and see the switches/inputs working. But when I move with jog or gcode they have no effect. Also I can go right past the soft limits. I must have something turn off but I don't know what.

If your country requires 220 volt peripherals (water pump or air pump) for the blackTooth laser system, then we will either send the 220/240 volt equivalents, or we will have them drop shipped from another location in your country, or a country with compatible power requirements.

What's the cure for 110 volt pumps (air and water) and a 110volt laser power supply, in a Blacktooth Kit sent to Australia, where 240 volts is pleasingly normal. The fan and other power supply are 220 volts.

New clues. I loaded a different profile I have used for another machine and my Black Toe moves. Of course all the settings are different. I load my normal profile and no ports, pins, or outputs light up.

Lost Comm with steppers: I have been running Mach3 with my Black Toe for years. This morning, I booted up, motors locked up. Started Mach, hit reset, and nothing. Can't move. Checked plugs. Diag screen says OK. What to look for? I have the BYOCNC Computer/contoller box.

This is most likely a wiring issue. I would disconnect all of the power to the drivers and reconnect one at a time to isolate the problem.

Additional Information:
that was not helpful. I already did that way before submitting this question. there are not that many wires here and I have already rewired this a few times. I actually think its a software or interface board issue because it does work sometimes but then trips (possibly a amperage / voltage issue) I am using the interface board that has a parallel port and usb for 5V. are there different settings that I need to setup?

I'm using the big 651oz in stepper motor for X and Y and the smaller 325 for the z and X and Y keep tripping when I try to tune the motors on Mach3 but Z seems to work. I have to turn power on and off to reset....is this a wiring issue?

Which controller card are you using?

USB connection can not move the gantry, it is connected but noticed in device manager is missing drivers. PCI serial port... any help would be great also there is two mach3 profiles one showers numbers moving as like the gantry should be but is not.

Make sure all your bolts/screws are tighten correctly and if using a lead screw make sure your anti-backlash nut is not offset. Now a default setting will be 10101100 for your driver dip switch settings and in motor tuning (mach3) 1600 steps per, 400.02 velocity, 4 in acceleration. now the acceleration and velocity can be adjusted to move your machine faster, but if set to high they could stall. Make sure you have the correct wiring from your motor to your driver (https://www.buildyourcnc.com/Documents/PN.SM60HT86-2008BF-U%20(inhouse%20PN.60BYGH303-13)%20(1).pdf).

I have your Nema 24 electronics kit and am having problems with the Z axis dropping over time. I am using a PC 8902 motor. Any ideas on what the problem is? What should be the motor tuning values in Mach3? Thanks

If some axes are not moving in two directions, the direction signal is not making good contact at either the controller or the driver.

I have USB Interface board. All axes are working if using MDI , using program some of the axes are only moving one direction. Example using Gcode X50 Y50 Z50 and then X45 Y45 Z45 then online one of the axes is turning correctly. But also shows on Mach3 screen that all axes are moving correctly.

Yes, you can use a corner plate very easily. You will want to make a corner plate that has three independent plates that do not conduct with each other. Each of these plates will be connected to a different input (i.e. IN1 for X, IN2 for Y and IN3 for Z). The end mill or tool that is inserted into the spindle will connect to V- of the 24V power supply, or the DCM on the controller, which is connected to the 24V V-. Then, you can use the ref all home button on the program run screen of Mach3.

I have the mach 3 USB board running a XYZ router, and a Z touch off (button style @ fixed position). I am wondering if there's a way to also use an X,Y plate that will only be responsible for corner finding. Is the digitize input the only input that can be used for a touch plate?

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.

I also place the controller very close to the drivers (on the back of the gantry). All of the cables are shielded. The only long cables are the mains power cables and the USB cable. The USB cable is shielded and contains active repeaters.

There is no problem putting all of the electronics in a box and using long cables to the motors. This is the way I did it for a very long time.

Great site. I saw your videos of wiring the Mach3 USB controller. You place the drivers next to the Steppers. This means that you have very long leads to the USB Board? What about the placement of the controlling PC? Is it a problem to have the USB board, PSUs and Drivers in a control box and long leads to the steppers? Thank you.

If the Z-Axis is moving down when you press the page up or page down (or by moving the z-axis by another means like with an MPG, Pendant, or the built-in MPG in Mach3), then the direction signal wire is not connected correctly. The direction signal wire works by moving in one direction with a low signal (like gnd) and moving in the other direction with a high signal (like 5v). If the signal stays at one of the two signals, it will only move in the direction of the current signal state. Recommended action is to determine if the DIR- and DIR+ signal wires are connected securely and make good contact at the driver and controller sides.

I installed a pokeys57cnc and use Mach3 for the mill. When I page up or down the Z axis moves down. Is there a setting I need to change? I checked the Z axis wiring and it matches the X and Y axis which function correctly.

To make an axis move in the opposite direction to what it is currently moving, you will need to toggle the ":direction:" active low setting for that axis. for instance, if when you press the page up button and your z-axis move down instead of up, then you need to make this change in the configuration.

To do this in Mach3:
- Click on the config option in the top menu
- Click on ports & pins
- Click on the motor outputs tab
- on the axis you wish to reverse, click on the "dir active low" to toggle the state of that parameter.

I can send you a new license. All you need to do is email me at customerservice@buildyourcnc.com and state the name the license is under and I will send you another license.

I bought and downloaded about 2 years ago, recently my PC that I use for my CNC crashed and now have to reinstall Mach3 but the license download has since expired. What I need to do to activate the software?

It's generally acceptable to use one pin for all of your limit switches wired Normally Closed (NC), and another separate pin for a Z probe that is Normally Open (NO). LinuxCNC is quite flexible and allows for mixed configurations of NC and NO switches.

Just ensure you configure LinuxCNC correctly to recognize each pin's logic (Active low or active high). And perhaps run a few tests before running the machine.

[59] is it ok to use one pin for all of the limit switches wired NC and another pin for a z probe that is NO, or do all input pins need to be the same (NC or NO)? I would like to use LinuxCNC but will use Mach3 if necessary. a thanks!

In the mach 3 software there is a setting that can be check to allow either a high or low to trigger you motor. In Mach 3 Config/Ports&Pins/MotorOutputs/StepLowA will enable the motor with a low Voltage.

Adjust the motor outputs to there corresponding step pin/direction pin(if setup is following our diagram):
Step Dirt
x 2 3
y 4 5
z 6 7

I'm connecting my PCI-e parallel expansion card to my 5 axis parallel port breakout board. However, the 3.3 volts coming out is not triggering servo step. I can measure hi/lo coming out of the parallel port when using Mach 3. Is the low voltage likely the issue or should I look elsewhere?

If you select the Settings Page and select or tick Auto Limit Override - this will allow you to back off the switch.

Hi there, when the gantry bumps up against a limit switch and triggers it, how do you tell Mach3 to allow me to jog the motor away from the limit switch? ie: I can't press RESET because the limit is open.... how do I move it? Thx.
