Further screenshots - showing the order given by Arrange funtion: Especially note that instance 5 and 6 (printed last) are in front of the other already printed instances, so rear wiring is likely to strike the instances 1 and 3 (second row back). ££££ :(
This is similar to https://github.com/prusa3d/PrusaSlicer/issues/486 - but with instances you can't drag/drop to change the printing order.
Yes, #486 (closed?) seems to be similar problem but for Objects, not Instances.
The Arrange issue seems the same is both cases: both Instances and Objects are not positioned optimally/logically as outlined above?
Version
Version 2.3.0+win64
Operating system type + version
Windows 10 Pro N Version 10.0.19042 Build 19042
3D printer brand / version + firmware version (if known)
Standard factory Prusa MK3S (purchased 2020). Firmware version: 3.9.3-3556
Behavior
1) Print setting >> Complete individual objects ("CIO") >> ENABLE
2) Add instances (eg six of single body) 3) Arrange
The Arrange function correctly heeds the 'CIO' setting and spaces instances correctly... However, the order/positioning on the bed seems 'unusual', not as expected (the logic is unknown/unclear)
The instances on the bed (eg six instances) were: two rows (across bed) x 3 deep
The print order was:
Problem
This is OK for short models that are below the wiring loom (at the rear of the printhead). However, for taller models, this may cause the wiring to catch an already printed instance.
Current work-around
The instances are numbered and printed in that order, so each instance needs to be re-positioned on the bed, to match the print-order above.
For example:
last row........ [6] [5] << 5th and 6th instances next row...... [4] [3] front row..... [2] [1] << first instance on the right
This manual process is awkward rather than complex, but:
Suggested Improvement (&/or clarification of logic? )
Arrange (certainly when CIO enabled) should perhaps:
Comments:
CIO and Arrange are brilliant features, but I think this change/option could make it more effective, safer and less wasteful too?
CIO has saved me many hours - especially when the last (e.g. 6th) instance is the one that fails near to its completion!
Project File (.3MF) where problem occurs
No 3MF file included - it's easy to replicate with any single object and multiple instances etc
screen shots
Added 3 screenshots - showing manually positioned instances
Hope that all makes some sense! :)
Thanks.
