Moving modifers to "0"  

RE: Moving modifers to "0"

Yeah I see what you mean.  Its obviously got a check on that field to stop entering of zero for some reason.  No idea why.  If you enter 0.000000001 or similar it replaces that with zero though.  I hadnt noticed before as I usually just hit M and then move by grabbing the coloured handle for the axis I want to move in (not the centre as thats free move which zooms it to weird places depending on your viewing angle).

Needs reporting over on Github regardless so I'll open an issue over there.

RE: Moving modifers to "0"

Hello Neophyl,

thank You for your reply and reporting on Github. Insering 0,0000000001 somethimes replace it with 0, somethimes not.

Ok added the issue https://github.com/prusa3d/PrusaSlicer/issues/3031   it also seems to apply to the part itself as well as modifiers.  

RE: Moving modifers to "0"

I wish the issue were just with zero; but many combinations get ignored.  Often seems to be time of day related.  The Prusa Slicer UI is not defect free.

RE: Moving modifers to "0"

Modifiers have a z height and their location is measured to the midpoint. If you have a 10mm high modifier and set z location to 5, it should be on the bed.

RE: Moving modifers to "0"

Bill thats not the issue here.  What was reported was that Prusa Slicer under certain circumstances wont let you enter a zero in the field controlling position.  It doesnt just happen to Z it can also happen on many other fields.

Also if you want to place a modifier upon the bed you don't have to work it out mathematically any more, there is a place to bed icon on the right hand side next to the x/y/z position fields to make that easy now.

@neophyl

Almost invisible that icon, but welcome. So is there a circumstance where zero is a valid entry?

RE: Moving modifers to "0"

Yes there is a lot of times when zero is a valid entry.  For example if you want to move a modifier so its half way through the bed 🙂  It seems that not everyone is having the issue entering zero and they can freely do so, and when it is having problems letting you type in zero you can get around it mostly by entering in something like 0.000001 and hitting enter which replaces it with zero which it will accept at that point.  

Its not just modifiers or those position entry fields we have seen this with though, it also applies to positioning models themselves through the text entry fields and one instance where a user tried to enter zero in as a retraction distance wasn't accepted by the UI.  That field has nothing to do with position so it looks like a more general issue.  What causes it though I have no idea.  I usually use the coloured handles to move stuff around and it was only after Stefan posted that I tried to duplicate the issue and had the same problem.  

I'm sure the devs will figure it out 🙂

Hello,

if You want to aline a modifer or a part , which belong to a original Part, at the x -or y-axis of the original part.

Sounds to me like zero is programmed as an invalid entry but the prog is accepting anything non-zero. Be interesting to see the dev's response. I'll go subscribe to the GitHub issue. Thanks.
