Cura 5.0 will not slice for full 330mm on the X

Posted · Cura 5.0 will not slice for full 330mm on the X

I know this will only affect 0.001% of the users out there, but I sanity checked and the issue does not exist in 4.12.1, which I have been using.

 

I have a model which is EXACTLY 330mm wide.  (I will post the .stl if necessary)

 

When I first did test prints I set things up according to a previous post detailing what needs to be done to get full build volume, things like no auto-generated supports, zero travel-avoid distance, no skirt/brim and I always got successful slicing for a full-width print on 4.12.  Now I'm ready to do the 'production' print.

 

I was intrigued by the promise of a faster build time (this is a 2+ day print) so I said 'what the {heck}' and downloaded 5.0.0 and gave it a try.  (Ubuntu 20.04.3 LTS on a fairly beefy desktop)

 

When I loaded and centered the model, it remained grayed-out (zebra-striped) and I could not find any obvious setting that was interfering with it.

 

I played around a bit with scaling of the model, and I found out that 329.4mm is the magic number at which it would slice.

 

Am I missing something here?  Is there some other setting that needs to be tweaked?  Is this a bona fide bug or issue with 5.0?

 

I went back over to the 4.12 version and it sliced just fine, and I figured I would use that for the actual print, which is running now, rather than give up a fractional percentage point of the width.

 

Speaking of settings, I quickly noticed that the supports on build plate only or everywhere option is missing (by default).  I assume that this is buried in the preferences menu, but this is a very important option, particularly when you are using externally-loaded support shapes.  IMAO, it should always appear by default.

 

Thanks.

      • S-Line Firmware 8.3.0 was released Nov. 20th on the "Latest" firmware branch.
        (Sorry, was out of office when this released)

        This update is for...
        All UltiMaker S series  
        New features
         
        Temperature status. During print preparation, the temperatures of the print cores and build plate will be shown on the display. This gives a better indication of the progress and remaining wait time. Save log files in paused state. It is now possible to save the printer's log files to USB if the currently active print job is paused. Previously, the Dump logs to USB option was only enabled if the printer was in idle state. Confirm print removal via Digital Factory. If the printer is connected to the Digital Factory, it is now possible to confirm the removal of a previous print job via the Digital Factory interface. This is useful in situations where the build plate is clear, but the operator forgot to select Confirm removal on the printer’s display. Visit this page for more information about this feature.

      • Ultimaker Cura 5.6 stable released
        Cura now supports Method series printers!
         
        A year after the merger of Ultimaker and MakerBotQQ, we have unlocked the ability for users of our Method series printers to slice files using UltiMaker Cura. As of this release, users can find profiles for our Method and Method XL printers, as well as material profiles for ABS-R, ABS-CF, and RapidRinse. Meaning it’s now possible to use either Cura or the existing cloud-slicing software CloudPrint when printing with these printers or materials
