Are you trying to determine how to wire the switches or where to place them on the Vertical Laser XL? Let me know and I will provide some pictures or video on how to do this.

Additional Information:
Kind of both. Have somewhat of an idea as to how to wire them but you included rotary and other limit switches. Not sure which ones to put where. Never worked with these before.

Do you have a more detailed diagram of the rotary and 15A limit switches on the vlxl?

You most definitely should have received limit switches in your package. We will send you the missing limit switches.

But to directly answer your question; no, limit switches are not needed with CNC machines. You can set up soft limits to make sure the machine does not go out of bounds.

With that said, if the motors stall for some reason and the computer does not know the actual position of the gantry or the spindle, then the machine may actually go out of bounds and the machine may hit a physical limit. With or without limit switches, the machine will stop.

Additional Information:
Please call the office so that we know who you are and we can send the limit switches to the correct person.

There are no limit switches in my Greenbull 5x10 kit. Are these no longer needed?

I don't see anything in the datasheet for the relay that indicates an overheat condition. While the relay is engaged, the power consumption is 400 mW and I don't believe this is enough to raise the temperature faster than the heat dissipation from the metal on the leads through convection or radiation outside of the rated temperature working ranges providing that you maintain an ambient temperature range within -40°C to 85°C (with no icing or condensation).

IS IT OK TO LEAVE THE VACUUM PRESSURE CONTROLLER PLUGGED IN ALL TIME WHEN PUMP SWITCHED OFF?

The 5V power required for the breakout board can be a simple USB male to male cable, that will connect from your computer to the board itself.
Now adding a external power supply make sure that it does not exceed a total of 5V and the standard 500 MilliAMP - 1 A.

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.

IS THERE A WAY TO GET RID OF THE PARALLEL CABLE AND SOMEHOW USE USB ?

If your computer does not have a parallel port, all you will need is a low cost PCI parallel adapter card (these can be found on amazon for $15-$20). If you plan on using a laptop (not recommended) you can try to find a PCMCIA parallel adapter, but many people have frequent issues with this setup. A more expensive solution would be to purchase a USB smooth stepper board. Unfortunately, we do not supply any of these adapters and cannot attest to their reliability.

MY COMPUTER DOES NOT HAVE A PARALLEL PORT. HOW DO I INTERFACE WITH THE BREAKOUT BOARD?

The wire that we sell for the limit switch wiring is here: https://www.buildyourcnc.com/item/3d-printer-component-cnc-electronicsandmotors-cable-wire-3-conductor-22-awg-wrcon-cablewire3conductor22awg

This is shielded cable to make sure there isn't any external interference with sensitive components and long wires associated with limit switches. This is necessary due to the interference caused by the motors on a CNC router and the milling process.

Additional Information:
So unshielded is cool. That's what I was curious about. Cheers.

Additional Information:
Absolutely. It's really the only type of cable I would recommend for connecting limit switches.

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

MY COMPUTER DOES NOT HAVE A PARALLEL PORT. WHAT DO I NEED?

If you are using the AWC708 or equivalent laser controller, the limit switches will connect between the EL input terminal and the GND terminal in normally open (NO) connection. Most limit switches can be connected as NO, or normally closed (NC).

For instance, a limit switch for the X- limit will be connected from the ELX- terminal to the NO connection of the limit switch, then a connection from the GND terminal on the laser controller to the COM connection to the same limit switch.

How are limit switches connected to the AWC708 controller?

We recommend using shield wire for wiring the limit switches.

I recently wired my CNC machine with limit switches and tested them before mounting to the machine. They were configured and when tested worked great. After mounting them to the machine, they continued to register as triggered. The frame of the CNC machine is made of MDF so I don't think it is shorting off of the machine. Can you tell me what might be wrong?

I have not come across this problem, but there may be USB, or firmware issues that you are experiencing. I would recommend going on the polabs website and using their support center (https://support.poscope.com/)and posing that question to them. Also, have you tried the ethernet port as an alternative to see if that helps?

Here is the response from an LLM:

Check USB Cable and Port: Start with the basics. Sometimes this error is due to a poor USB connection. Ensure you're using a high-quality, shielded USB cable and that it's plugged into a USB port directly on your computer, not through a hub. If possible, try a different USB port or a different cable to rule out any issues there.

Update Firmware and Software: Ensure that both your PoKeys57CNC firmware and the Mach4 software are up to date. Firmware updates for your PoKeys board might include optimizations or fixes that address connectivity issues.

USB Polling Rate: This error can also arise from the USB polling rate setting in the PoKeys configuration software. It might be set too high for your system's ability to handle it. Try lowering the polling rate and see if that resolves the error.

Computer Performance: Check your computer’s performance. If it’s running several heavy applications simultaneously, it might not be able to process signals from the PoKeys board fast enough. Try closing unnecessary applications or consider using a dedicated machine if your current setup is too taxed.

Mach 4 and PoKeys Plugin Configuration: Dive into the Mach 4 plugin configuration for PoKeys. Ensure that all settings are correctly configured as per the manual. Incorrect settings might lead to communication bottlenecks.

Connection Quality and Interference: Consider any potential interference sources near your CNC setup or computer. Electromagnetic interference from large motors, other electronics, or long cable runs can affect communication quality. Try rearranging your setup to minimize interference.

Consult Documentation and Support: If the issue persists, consult the detailed documentation provided by PoKeys or reach out to their customer support. They can offer more specific advice based on the latest product updates or known issues.
