Dual Z axis safety

tom33

Hi,

I use a dual Z axis on my machine with 2 1XD board for auto alignement at start.

There is a way to stop the machine if one of the 2 motors doesn't move ?

I use 2 nema 23 with brake and encoder and leadshine cs1 d507s as driver

Thanks !

nobody has the same problem ?

So there are times when one of your Z steppers doesn't turn?

When is that happening?

Thanks.

@tom33 Why should one motor not move ?

@tom33 Well, I had the same problem with two Nema23 motors on the Y-axis. It ripped apart my CNC machine.
What does the leadshine provide (unknown driver for me) about cross-referencing the encoder signals?
Does it have an error output-signal you could link (in series) with the other drivers enable signal?

@pcr Is to prevent if an extension board doesn't works or a wiring problem,...

looking at the data sheet there is an Alarm output (which you could connect to the Duet to pause the machine using a trigger. There is also a reset input which you could connect to a IO output to reset the alarm if you wanted to be able to do that.

@pcr bad cable/connector, dead driver, controller board that has gone insane...
