I have a toocaa laser. It has been running well with LightBurn until recently. I had paused the burn and shut the lid to my laptop. when I came later the program had to be aborted. But now it jumps along the carrige (east-west) I shut down the computer, reinstalled the program and the problem still exists. Any suggestions? Thank you
Look for a partially inserted plug for the Xaxis. It could also be a broken (intermittent) wire.
