Hi all!

I'm new to the forum and i hope this is the right section. Concede me some writing errore because i'm italian and my english isn't so good.

I've tried emc2 and immediatly noticed that there isn't a HOME button (or i can't find it maybe =) ) that let me to put the axis to their home with one click.

The procedure for doing it is:

G0 z(safe z)
g0 x0 y0
g0 z0

Is there a way to do it automatically or have I to insert the gcode in the MDI each time?

I hope you can understand my question and answer me.

Thank you very much

Michele

You can add a go to home position button using pyvcp or use G28 or G30 to move to home or have your home moves in a subroutine.

Thank you very much John! I've got another question for you. I've set my axis speed like this:

X axis: 500mm/min
Yaxis: 4000mm/min

My g-code is a zig-zag poket and i want, only for test with a pencil, to draw it on a sheet. So i want to cut at the maximum speed of my axis but, all the axis are limited to X maximum speed even when it is stopped cause only Y is working. Have you got a solution to this?

Check the MAX_VELOCITY setting in the [TRAJ] section.
