Z-axis up without homing macro
-
I tested it and that works great thanks.

If I am away from my house and I have to cancel the print because of a problem my printer is no longer homed. I just wanted to be able to raise the head so it doesn't cool down setting on the part.

Why do you think canceling a print un-homes the printer?

It would depend on what you have in cancel.g I think.

Well yes that certainly could happen.
Though why there would be something in the file to do that escapes me at the moment. I haven't found any reason to date to do something that would un-home the printer.
Curious.

For instance in my cancel.g I home XY and then turn the motors off.

Why do you turn the motors off?
For me most times a canceled print is quickly followed by another attempt after an appropriate change or two.

I suppose just for noise. To start another print it would be re-homing anyway, and depending on why and when it was canceled it might be awhile before another attempt is made.

Noise?
Do your steppers make noise when not moving?

Yeah there's a slight hum/whine when energized. Nothing too offensive. When I was setting up the macros I figured why not power them off?

Evidence that great minds don't always think alike.
