upper right Emergency Stop shuts down everything.

It's all relative to the extruder nozzle, which is at a relatively +Z position when the bed is lowered.

Edit: I suppose the right thing to say is that it's relative to the model space where the head would extrude...

I use RH , latest version. Do you mean in printer settings/printer shape /print area depth? One more thing that I think is odd that on the manual control tab the+Z arrow moves the bed down, I would think the - Z would do that.

the number will a little less than 200 depending on your z stop on a SD3

The best way to figure it out is zero the z axis them using RH move the bed down to about 180 or so then move it by the 1mm step until you hear it stall, look at the coordinates for z and use that number -1mm of course.

Do you use repetier? You need to go to printer config and define your Z-axis limits. Mine is 151 or something about that much.

Sometimes when I am moving the bed down I inadvertently move the Z arrow in RH past 200 and the bed tries to go there.If I am not right there the bed bottoms out and tries to keep going down, makes a terrible grinding noise. The only way that I have found to stop it is to power down the printer.I thought "turn off motors" would stop it but doesn't.
