I recently installed the limit switch kit in my Crossfire and upgraded it from the old Mach 3 controller at the same time. The home to limit switches works perfectly but when the Y axis leaves the home position it is numerically running in the -Y. Has anyone encountered this before? Machine works fine if I turn off the limit switches and run the y axis from the opposite end from the limit switch. It’s almost like a software glitch.
Uninstall limit switches.
Store them away never to be used again.
The setup instructions for the limit switches are borderline confusing re-read it and follow them through again.

These tables are small; never saw a need for them as they offer no real benefit.
Maybe I’m just weird like that but I’ve owned two tables (Crossfire with XL and Crossfire Pro) and put a ton of hours on them and never used limit switches.

Since the “home” is at the maximum Y positive point, all movement from that “home” position will be in the Y negative direction.
As long as it homes the correct direction, it’s working correctly. If it homes in the wrong direction, you need to reset defaults in Firecontrol.

So what you’re telling me here DS is the home to limit switches was never supposed to return the machine to zero X / zero Y? If that’s the case this “upgrade” is completely worthless. Mounting the switch at the zero end of the Y axis and a minor software change from Langmuir maybe?
read the second post again. 
More like reinstall the Mach3 controller! That knows how to process limit switches…

That’s my gripe about the switches as well. Home to me should not be the top left. It should be the bottom left. Or the default point of origin for loaded files should be the top left.
Not being able to adjust those preferences peeves me.
Limit switches do serve a purpose in preventing you from trying to cut something that may barely exceed the travel, and when used correctly can help you salvage a cut when you lose work zero, but other than that your table will be just fine without them.
I used my table for a long time without, crashed into the hard stops all the time, it’s fine. If my switches broke tomorrow I would not replace them.
I did salvage one cut based off the limit switch capability, but that’s once. Lol.

The home position on any Langmuir table with limit switches is the back left corner. I suspect that the reason was to keep the torch in a safe spot for loading material.
It was never meant to be the X/Y zero. You have to zero the torch wherever you want to cut your parts on the material.
I’m another long time user of a Pro table without limit switches. It might occasionally rescue a failed cut, but the trouble they cause isn’t worth it to me.

If I had realized it didn’t take the machine to zero/zero I would never have bothered with it. Seems like a poorly thought out offering from Langmuir. Thanks for the info.

I have been puzzling what I did wrong with this thing for a few days but apparently I had it right all along. It just isn’t what I expected, nor what I want it to be. Poorly thought out upgrade. Home to zero/zero would be much more helpful imo. Thanks for the info.
I agree home should be wherever the user chooses it to be.
A parking routine would be an awesome upgrade to fire control as well.
So at the end of a cut it’ll wait for the Post purge to finish, then moves the torch off to a chosen parking location.
