Anyone have issues with the touch screen stop working mid cut. The cut finishes but the next cut doesn’t arc. If I unplug the touch screen and plug it back in I can usually generate and continue. Or just use the jog pendent. I have had an issue a few months ago to where the screen acts like I am repeatedly tapping the corner. Although this issue hasn’t happen since then. Debating keeping the touch unplugged and just using a mouse.
Those symptoms are consistent with EMI (noise) interfering with the data signal between the MC4000 and motion control board (MCB) inside the Langmuir electronics enclosure. The most simple and effective first step would be to verify that all noise-filtering elements (ferrite chokes/USB isolator dongle) are functioning and installed properly. All components MUST be installed/connected to the SAME USB cable which transmits data to the MCB inside the enclosure. If any of the 3 components is missing or has malfunctioned, software crashes and reliability issues while operating should be expected. Please see the attached photo for EMI filtering equipment identification and installation location.
I ran into this issue with mine, it was basically the only real issue i ran into with my xr. I did have a few other minor issues but they were corrected easily with tech support. But i was never able to solve this specific issue. I ran mine like the picture johnny provided. I also tried using multiple extra ferrite chokes, diffrent power outlets in my shop for power to the screen and mc4000. But nothing i tried ever solved the issue. This was very frustrating as i wasted several large sheets of metal when the screen froze 70-80% of the way threw the cut and couldnt successfully reload or restart the cut. I ended up pulling the screen from my machine all together, and have been running it with my laptop with no issues so far. Although this isnt a perfect solution either, being as firecontrol is setup really nicely for the touch screen provided. But it came down to the cost of wasted materials to me so loosing the touch screen was better than several hundred dollars in material.
Won’t let me upload a video. But the problem where the touch screen acts like it touching and moving everything just happened again. Always in the top left corner. Right on start up. Plasma not even turned on yet
