Two steps forward, and one (or two) step(s) back.Īttached is a photo of the router today, the clutter is in keeping with the current confusion. Local ebay prices what looks like an identical power supply with free postage from Sydney for $36. The errant D13009K device is China unique, but probably available. The power supply has blown the input fuse and one of the front NPN high voltage transistors displaying a smoke trail. still no power, the 24 V power supply is dead !Ī review at home of documents reveals the Grbl has a parameter list with one parameter listed as a boolean for 'Hard Limits', probably just needs resetting. resetting of circuit breakers at the distribution board, decision that something is wrong with the Arduino/Grbl software, cursing new designers unaware of 50 years of digital design and numbering of pins and ports, discover the digital inputs are numbered from 0, not 1, so the pin numbering is out by 1,
counting of pins and measurement of voltages as limit switches operated, cursing of the way the Arduino is stacked at the bottom and the small box the unit is in, find a document stating Pins 9, 10, 11 as the Arduino digital inputs for limit switches. checking of switches to ensure they are NO and the drawing wrong,
the wiring diagram shows NC switches in parallel, a lot of examining and checking of wiring, When we tried the limit switches, no stopping it.
