A bit about my machine;
It's a converted Hurco KMB1 that I did a few years ago but rarely use it, so I'm still finding the odd bug.
My limit switches are 24v proximity switches, so there are no moving parts. Since I built this machine, everytime I would TIG weld near it, the machine would shut down and display a "limit switch trigger" fault. So I don't TIG wels anymore when the machine is running. The machine used to trip also when relays would activate, but I fixed that problem by putting capacitors across the pull down coils.
In the past couple of days, the "limit switch trigger" fault shut my machine down 3 or 4 times right in the middle of a program for no absolute reason !! I had a 1/16 cutter carving wood, so there was no load on the machine. I tried to watch the Diagnostics screen to see if I could see a light flicker if it happened again, but of course it ran great afterwards.
Any ideas? Has anyone experience similar problems?
Thank-you, Dan
