Rotating Generic Box about Z axis actually rotates about Y

Operating system type + version

Windows 7

3D printer brand / version + firmware version (if known)

I3 Mk3

Behavior

• Describe the problem Modifier boxes import already rotated 90° about X. trying to rotate about Z rotates about Y instead. The arrows that show up to show direction of rotation show proper about Z but the actual motion is about Y.

• Steps needed to reproduce the problem Import modifier box and rotate about axis. Directions appear to be miss-coded.

  • If this is a command-line slicing issue, include the options used

• Expected Results Modifier box to rotate about Z axis corresponding to the Z axis of the printer or Z axis of the modifier.

• Actual Results Box rotated about printer/object Y

  • Screenshots from PrusaSlicer preview are preferred

I think its because the axis are fixed relative to the enforcer. Its more apparent whats happening if you rotate your enforcer 45 degrees around X first and then try and rotate around Z, The Z (and other axis) moves with the part rather than staying locked to the World space.

Wether that's a bug or intended design operation I don't know but both methods are certainly valid ways of handling it.

I agree that the axes move with the enforcer, and I think that this behavior would be fine and perfectly logical if it was consistent. My initial problem was that when the enforcer was first created it was rotated about X by 90° already. Then, when I wanted to rotate about Z, which was the long axis of the enforcer (the 30 mm edge), the enforcer did not rotate about the long axis even though the arrows displayed on screen seemed to show that it would.

An additional and probably related problem I have just found is that the rotation, axes orientation, and scaling of the enforcer is not persistent and resets to an odd orientation. When I reopened my .3mf file to respond to your comment, I found the rotation, scaling, and size had been reset. All rotations were 0° and all scaling was at 100%. This caused the originally rotated part to have dimensions of 28.28x28.28x10 (xyz) rather than the original 101030. With dimensions of 28.28x28.28x10 and with the enforcer in the orientation shown, this indicates that the coordinate system that the enforcer defaulted to has Y up (along machine Z) and Z to the front of the machine (along machine y). This is confirmed by the way the arrows highlight on screen when you click into the size text field to change the size of the enforcer.

I'm finding that the rotation is just completely off on any modifiers --- the axes do not align properly with X, Y, and Z.

I think the "reason" it's doing this is because it's aligning the axes per however the part that the modifier is attached to was rotated. In this case, I set the back face of the part to the bed. So the modifier seems to be picking that up. Unfortunately, that renders the modifier useless in that one can't effectively manipulate it into the correct position.

I just added a modifier and here are the default axes available for rotation:

Due to this issue, I may have to downgrade back to 2.1 as I simply cannot use any modifiers because I can't put them in any position. By default the rotation is set to the below values when I add the modifier.:

Again that's before I've even touched the modifier, but after placing the part on a particular face.

If I set those values to 0, then the modifer shows as:

I think my problem is related to this one. When I move the Enforcer box in the Y axis, the Z value changes in the Part Manipulation Position box instead of the the Y. Makes me wonder if the Y and Z got swapped.
