Torch light off and no Fire control connection [Solved]

[Leemers]

Hi new here,

Just bought a used table (1yr old) crossfire XR. I’m slowly figuring out how to set up. I linked my machine to FireControl and was jogging it around the table, then I sent it back to home and when it docked in the corner of the table, the torch lights turned off and it disconnected from my computer.

I’ve tried redownloading firecontrol but I cant seem to get it connected again or to get the torch lights on. There’s power to my control box and I can hear it humming, and the fuse in the back is intact but no table lights.

FireControl grayed out? Well?

Your computer’s USB port powers the control board inside the control box. If FireControl is grayed out on the computer, you may have a cable issue. For the limit switches, go to the top right of the fire control panel, click on the three bars, turn them off, and then hit save. @Leemers

limit switches wont turn off torch lights. Maybe look and see if any cables got pinched when it homed

Don’t feel like to have to turn off the limit switches. There is a what appears to be what I would call a GANG of people on this forum that are spreading propaganda!!! There goal is to eliminate all limit switches worldwide. Please BEWARE

I would try something as simple as getting a laptop or another PC, installing Firecontrol, and connecting it to your table.

This is just going through the simple troubleshooting of whether or not it’s on the computer end, the cable (try another one), or the table.

If the issue persists while connected to another computer, with a different cable, then disconnect the limit switches to see if it comes back to life.

I didnt see any damaged cables. Also the machine didn’t come to a stop on any switches but I also dont know if it’s programmed to bounce off the switches before coming to rest.

I’m planning on replacing my computer cable tonight so I’ll try that as well

So if limit switches are tripped or faulty, the torch lights won’t come on?

It’s just easy troubleshooting.

Troubleshooting consists of changing one variable at a time as a process of elimination.

Much of this can be done in a matter of seconds.

Please report back with whatever works! A new cable, or even just a different computer will be an easy step to perform.

When homing The gantry will move to the back left comer and will stop when it contacts limits. It then moves back maybe a 1/32” and then the green light on the torch goes solid green. If the limits get tripped during operation the torch light turns red can’t remember if it flashes or is solid

Tried new cables and a different computer and a few different versions of fire control. Also tried unplugging the limit switches all to no avail

Bad news is still good news - we now know what isn’t the issue

Email Langmuir to send you a new control board. They go bad on occasion. They will get you taken care of.

[Leemers]

Ok, I read about that being a problem on other forums. hopefully boards aren’t too pricey

[Bigdaddy2166]

No, not at all. So your FireControl is grayed out correct?

[Leemers]

Yes tried other cables and computer

If you’re under warranty, you’re good.

If you’re not, they’re super affordable.

Make sure to ask for a relay as well. This is because some currently installed controllers have their relay glued on making it a pain in the ass to remove and place onto the new board.

[Bigdaddy2166]

Ok, then it is the control board. If it wasn’t grayed out, I would have you check the power supply inside the control box. The control board is powered by your computer’s USB. Langmuir is very reasonable and may even send you one. I cannot speak for them, but they have always been super helpful. Sorry about your situation. I had one go bad on my Pro and on my MR1.

Just make sure when you install it that it does not touch the control box housing. It will have isolation bushings behind it. The USB on the board is critical. Here is an example of a problem installation.

Thanks for the tip! I’ll give an update when I get it all resolved

[Leemers]

Thanks for all your help guys. I got a new board from Langmuir for free! Installed it and I’m good to go! Had a few troubles with limit switches but did my first few cuts.
