Steppers motors locked up

I have a new Lkngmill mk2.5 that has been running great for two weeks.

Super Ling Board controller and gsender latest version (as I have tried deleting it and reloading it 3 times)

Mac iOS

Today, my stepper motors on the y and the stepper motor in the Z lock up when the loser is on.

When I use gSender to try to move it, the bit on the visualized moves but the axis just makes a locking sound and goes nowhere (both Z and Y) x moves but slower than normal.

I have no idea what I might have done. I got new Sensors today which I installed to make sure they worked by watching them light up and shut off. I plugged them into the SLB to make sure it was also getting signal.

I do not have homing in and have restored the settings to default to start over several times.

When I power off the SLB the Z and Y turn freely and smooth.

@metalandwood I’ve moved your issue to a new topic, Jeff, so that it does not get confused with the other member’s issue.

You say that the Z locks up when the “loser is on”. Do you mean “laser”?
