Solved Setting z-offset on R1+

Hello,

Lately I have become accustomed to the R2, but now going back to debugging my R1+ with my newly setup Simplify3D installation, I am trying to determine how to adjust the z-offset.

When I go into the control panel in the attached picture and go to Motion -> Z-offset, it said -0.70 (specifically with the negative sign). However, when I go to adjust it to a different value, it only has 0.50 (positive) up through only larger positive numbers, nothing negative.

Furthermore, I might be imagining things, but it also doesn't seem to affect anything. For example, I had it on 0.80 (positive), then I selected "Store Memory", turned off the machine and came back and it was indeed set to that, but the print looked the same on the first layer with the nozzle very close to the bed. Just for effect, I moved it to 1.16 (positive) and still it looked much the same.

Am I on the right track with how to set this? FYI no matter what I select, the screen always looks like the attached, which I assume is because of the "G1 Z0.180 F1000" line in the gcode spit out by S3D, though I can't seem to find anywhere where that was specified in S3D at all for it to put that in the gcode.

Any experience or thoughts are welcomed on this!

 

Thanks much Geof. I do have stock firmware, but I'm really not a fan of doing the z-offset in the slicer because I want to be able to change it globally as I tweak performance and not have to update each file. What's so odd is yesterday I was doing the above steps and it wasn't working (and I swear I was doing the "save memory" and checking) but now it appears to be affecting the print. I had it at 1.16 and it was too high and I moved it to 1.0 and now it's fine. So I guess that really is the place I do affect things globally, but I'm still lost on what it was a negative number on the screen before and now I can't select anything but positive numbers. In a way it doesn't matter as it's working now, just a bit odd.

Thanks!
