Here is a picture of the Printrbot Plus, taken from the front , showing the printhead at the Home (0,0,0) position of X, Y, and Z. Positive values of X, Y, and Z move away from this position, using the same orientation as shown in the previously-posted photographs.

Is Home, the same for an simple Metal, as shown for the Simple?

And, do we position the hotend at Home, then turn on power?

Thanks

Home is the same on the metal simple as the simple. You don't have to home it before you turn it on. The home buttons in your host software will send it there. When you press home, the steppers will start moving each axis (one at a time) towards the home position. The endstops and z-sensor will stop the steppers when they get to the correct place.

I think home on the Metal Simple is at Y max.

OK. I am a newbie and I read the above post and am still confused. I have a printrbot simple. Is there a home button on the printer somewhere I haven't found? I have been trying to "home" my printer in Cura using the G28 x0 y0 z0 command. Is that right? Do I need to do that before each print?

[RetireeJay]

The printer itself has no "home" button, but Cura does. It has an overall "home" button, and then individual buttons for X, Y, and Z. They look like little houses.

Very often, "homing" is part of the start-up routine built into each part. That's because it also includes "bed compensation" (G29...) Either way, your printer does need to be homed every time you turn it on. As long as you leave it turned on, it should remember where home is.

Just to confuse things a bit, Printrbot decided that "home" on Simples for the last year or more is at Y = maximum, not Y = 0. So the definition of "home" depends on the model and age of your 'bot. But the Location X = 0, Y = 0 is still as shown in the pictures at the top of this thread.
