Are you using shielded wire? If so, take the shield to ground. If there are any other wires in the cable that is not being used, ground those as well. The customer can also try moving the cables as far away as possible from the motor wires and motors.

MY LIMIT SWITCHES ARE TRIGGERING AT RANDOM.

Let me check.

Additional Information:
We suggest wiring the X and Y axes. We haven't seen the need for wiring the Z axis, but that is totally up to the CNC user as their application may require this use.

I measured 13 feet of cable for the X and Y limit switch connections on the greenBull 5X gantry (2 limit switches on one gantry side for X limits and 2 limit switches on the gantry front extremes for Y axis limits). You will need to estimate how much more cable you will need from the gantry to the control box that you are using. I generally estimate the extra to be measured from the end of travel on the x-axis to the middle of the x-axis travel and then where you would position the control box from there.

No, you should not have received two parallel breakout boards in your CNC kit. You can return the extra item using standard shipping with COD. Our apologies for the confusion and the inconvenience.

WHAT CABLE LENGTHS SHOULD USE FOR THE BLACKFOOT CNC MACHINE

http://buildyourcnc.com/PrimeronHomingandLimitSwitches.aspx
There is a pin setting in Mach3 that says how to react to the inputs from the switches. Your setting is probably wrong as the trigger happens immediately.

You may want to think about shielded wire and/or a resistor on each limit switch line. If there are stray wires, connect them to ground. Additionally, the shield from the shielded cable insulation should alse connected to ground at both ends.
Try upping the Debounce interval in Mach3. You have to adjust the debounce interval. You go to config,general config, and it is in the top right corner. I set mine to 100 and it seems to work well.

THE SWITCHES KEEP TRIPPING! AT TIMES IT IS LITERALLY AS SOON CLICK RESET ON MACH 3 THEY TRIP AGAIN.

The greenBull can range is routing width sizes of 5 feet and 6 feet. The blackFoot has a 4 foot routing width.

Previous Solution:
The greenBull machine has a sturdier gantry than the blackFoot, so you can be more agressive with the cutting feedrate (cutting speed). The blackFoot is also a good machine, but it all comes down to the speed at which you want to produce the fabrication

The spindle is also highly recommended for it's quietness and easier cleanup (no fan blowing the dust in the air)

BYCNC Response:
This is correct. You will need to use a method appropriate for the software you are using. Also remember that NC switches are typically wired in series, while NO switches are normally wired in parallel.

User Response:
I am using the cnc planet software for your USB board. Are the limit configurations in this software?

BYCNC Response:
Yes, Planet CNC software is compatible with the use of limit switches. Configuration information will depend on your specific application. You can view Planet CNC's information here: http://www.planet-cnc.com/files/CNCUSBController.pdf

The DCM is DC common, or DC Ground which is used in conjunction with Forward (FWD, or FOR) to start the spindle in the forward direction.

The ACM is the AC Common, or AC Ground (Alternating current, or in this case, a variable voltage for spindle speed). The ACM is used in conjunction with V1 to provide variable speed for the spindle.

In order to use the terminals DCM/XGND, FOR/FWD, ACM/GND and V1/VI1, you will need to program the VFD to enable the terminals and disable the control panel.

YL-600:
Start/Stop - XGND or COM is paired with FWD or X4 (X5 for Reverse).
Spindle Frequency: XGND or COM is paired with AI1 and uses a top end of 5VDC

YL-620:
Start/Stop - XGND is paired with FWD (REV for reverse)
Spindle Frequency: GND (not XGND) and VI1.

The Start/Stop portion of the control panel and terminals is separate from the spindle speed/frequency control panel and terminals. Each of these have a separate programming parameter.

For the YL-600/620, the P00.01 parameter controls the source of the start/stop function.
Settings for the P00.01 are:
0: Control Panel is used and the terminals are disabled.
1: Terminals are enabled and the Stop on the control panel is still enabled if needed.
2: Terminals are enabled and the Stop on the control panel is disabled.
3: Control is sourced from the MODBUS also specified as the RS-485 connection. This would be labeled as RX and TX (Receive and transmit) and uses the UART protocol (serial communication protocol). https://buildyourcnc.com/FAQ/13381 explains this in depth.

There are three main LED fault signals that the DM556 and DM442 drivers exhibit. There is a red and green LED. The red LED will show the fault signals.

The fault signals are:

- Over-Current: If there is continuous current that is above 16 amps, the Red LED will flash every three seconds. Over-current could be related to: a short in the motor coils, or two of the wires of the motor are shorted; of the motor wires/coil is shorted to ground.

- Over-voltage: If the power supply output to the driver exceeds a voltage of 52 volts, the red LED will flash twice every three seconds.

- Phase Error: Is the motor wires are not connect, or they are connected incorrectly, the red LED will flash four times every three seconds.

What are the fault conditions of the DM556 and DM542 drivers?

There is very little radiofrequency (RF) energy exposure to people inside a building from a cellular base station located on its roof. There are several reasons for this. First, the transmitters operate at low power levels. Second, the antennas are normally mounted near the edges of the roof and are aimed away from the building. Third, most cellular transmitters use "high gain" or panel antennas. Such antennas transmit most of their energy in a narrow beam (in the vertical direction) from their front surfaces, away from the building. They radiate very little energy downwards towards the roof or backwards from their rear surfaces. Finally, building materials absorb a significant fraction of the RF energy passing through them. As a result, the RF signal levels at any location inside the building are invariably low and far below safety limits. The situation might be different in some locations on the roof itself. RF signal levels close to (within a few feet) and directly in front of cellular base station antennas can easily exceed safety limits. Some precautions are needed to prevent people from walking directly in front of the antennas while they are transmitting. This applies also to paging and other systems that use rooftop antennas, some of which transmit at higher power levels than many cellular base stations. Kenneth R. Foster, Ph.D.
