Our sophomore students are working towards creating their LED light boxes. I’ve been impressed with creativity in which the students are going about designing their boxes. These boxes are actually more complex than just 6 sides that fit together. It requires interior structure to hold circuitry, panel mount openings for sensors and controls, and means to open and fix in case it breaks. Here are a few pics I snapped today of their work.
Additionally, after school today I took a taxi to the airport for a flight to Phoenix. I’m speaking at an event tomorrow. Will write about that in a later post.
I believe it was Tuesday when I reported having some issue with my Tormach. You can read about the initial symptoms here. Fortunately, Tormach has very good support, at least in my opinion. I had also let Tormach know the automatic draw bar was not functioning, the lock and release buttons were not doing anything despite having good air pressure, and other air pressure related functions working properly. This led them to believe that the draw bar control board may not be receiving power, which would then affect the ATC, as both are used together during tool changes.
I put a multimeter on the draw bar control board and was not reading any voltage. I traced the wires back to their source at the electrical cabinet and also received not voltage at that point, which suggested perhaps a fuse had blown. However, while looking at the fuse board in the electrical cabinet I did notice a few small chips of aluminum on the board, which might be shorting out the board and causing the issue. I brushed those chips away and retested the wires numbered 501 and 502. 11.92 V showing on the multimeter, problem solved.
Looks like some chips somehow made it into the electrical cabinet and shorted out the fuse board, specifically the 501 and 502 wires to the draw bar control board. It took a day or so to track down the issue, but luckily it was an easy and cheap fix. Some photos below.
