All,
I had an issue last week where my THC just stopped functioning after 6-8 months of working fine. I was going crazy trying to figure out what was wrong, and I used the troubleshooting guide and the forum and saw that it says to ensure your computer is separate etc. from the THC cabling and the plasma cutter. I thought back to what had changed between the last time I used my table and the day I was having issues. Of course I had been overthinking, chasing wires with my multimeter etc. and pulling out my hair because everything was checking out. Well, the difference was I had plugged in my Macbook pro power supply to the power strip I use to power the electronics on the table. Once I removed the Macbook power supply the THC worked perfectly. Obviously the Macbook power brick was causing just enough interference to keep the THC from working.
WOW! I would never have thought that was the issue. But after a week of being upset about a failure, yesterday in doing that one simple thing fixed the issues.
The forum and guides are a very valuable resource, and the Langmuir community is very helpful.
Thanks again
Tony
