Just updated to the latest build.

The block "G53 G00 G90 Z0", to my understanding, should move only the Z-axis to the machine coordinate 0 and not move in any other direction. In my case the spindle goes all the way up.

However, since the update this block also moves X- and Y-axis to some coordinate what it shouldn't do.

Does anyone experience the same?

Hi,
I think Mach as it ships has two lines of code, one which includes X and Y axes and the other,like your example,
has code affecting the Z axis only.

If you go to the screen load script you will find it and then you can make the choice as to which code runs
and suits your machine and expectations.

I could be mistaken, but I thought the OP was asking about a line of Gcode, not Go To Machine Zero or whatever it's called. If he MDI's his line, or it's in a program, it shouldn't move X/Y, should it?

Hi,
if indeed it is just a line of code then no X and Y should not move. That line of code though looks like it came straight from the Go To Zero function.

Really the OP's block of code should move Z and only Z no matter where it is. If it's in the Go To Zero function, THAT block of code should only move the Z. If there are other G53 lines or if one G53 line also included X and Y, then more that Z will move.

Hopefully the OP will show up back here and tell us what's happening!!
