Hello, I've been having intermittent following errors on my Hurco VMX42SR for ages now. I retrofitted the power supply two days ago after researching threads here. That day after startup, calibration, warm-up, and running a program there were no following errors. Yesterday.. the errors came back.

The following errors don't seem to have any particular pattern as to /which/ axis will cause the error. I've noticed that the worklight will flicker right before the following error window will pop up, and will then keep intermittently flickering afterwards. Most of the time, it'll error during calibration, but sometimes during warm-up.

I'm really hoping the experts on this forum can provide some guidance... Has anyone had a similar issue? Does anyone have some advice or guidance on what I should test?
