So I thought I needed a new stepper, but turned out there was nothing wrong with it, which I found out when the new one I bought did the same thing. However, your machine isn't going bonkers, it's just locking up.īut, I've had that problem too, the X stepper would get into some nasty vibration, and would lock up. My LS900 has basically the same problem, except rather than a soldered connection breaking, a stepper wire just plain wore out, and started shorting out on the cabinet when the drag chain was in just the right position.Īnd the 900 would go bonkers when the wire was shorting out, much the same way the Triumph did. The problem was one of wires broke where it was soldered under the heat-shrink, it was okay until the chain would loop uphill when the broken section was in the loop the tension on the wire would pull the connection apart and the X stepper would go bonkers, until the chain flattened out again. The Triumph started doing nutty stuff at about 2 years old, and only in certain spots. Two of my lasers- my 'good' Gravograph LS900, and my Chinese Triumph 1390- have both had wire issues within the Y-axis drag-chain.
