X direction reversed & ramped speeds

I have a new MK2 48x30, setting up the 10 hole Vortex running the built in XYZ setup routine. All of the sudden, the machine reverses X axis commands and ramps up to speed instead of the precise movement it made yesterday. I’ve reset all the defaults to no avail. I probably switched the Y/A button without powering off. Hoping I didn’t do expensive damage. Any ideas?

Can you explain this a bit more? Can you jog the X axis?

Never mind, I think I might be misremembering my issue.

@brjustice In addition to Neil’s question, can you please post if you have set $1=255 on your LM? Since you mentioned that you changed from Y to A without powering down, this may be an issue.
