LO-X7 DSP X-Axis Problem

[Steve_M]

Hello All,

I upgraded my K40 laser cutter last year to the LO-X7 DSP and have not had any issues since the upgrade. The other day however I ran into an issue..... I was running a cutting job and the x-axis stopped moving. I power cycled the DSP, double checked parameters but found no issues. On a fresh power cycle I am able to jog the axis with no issues. After trying to run a file it stops working and then I am unable to move the axis even trying to jog. Again if I turn off power and try again all works until I try to run a file. Cut or engrave it produces the same result. I have not changed any setting so I am confident that is not the issue. I have also tried swapping the x/ y drivers and I see the same result on the x-axis with the other driver connected. Could I have a bad DSP card only after a few months use? Please help!
