Not unexpected, but is it predictable ?

[Michael GilliganParticipant @michaelgilligan61133]

Yes … I am both embarrassed and happy !!

I have no idea how it happened, but the troublesome .3MF file is much larger than the others in the set …

Why ?

Because it contains five instances of the same object, all co-located

I deleted four and re-sliced it … after which, it printed nicely

Another recommendation Michael.

“3D Printing Failures” (2022 edition) by Sean Aranda.  A bit pricey but has saved me many times from too much hair loss.

Forgot to say that there will be a tick box somewhere in the slicer setup that will cause a new version of the slicer app to open each time you send something to print.  It stops the co-location of objects but leads to the frustration of lots of windows open.  You pays your money etc

Thanks for your continuing advice, Alan

Keep it coming … this geriatric dog needs to learn a lot of new tricks.

Meanwhile, I have at last produced my set of tubular samples, which will be measured in due course.

… the simple idea being to to investigate how the printer handles dimensions that are  seemingly impossible to print with a 0.4mm nozzle.

Hi Michael, for dialing in performance when using a new filament type I print a 20mm cube with the slicer set for single outer wall, no infill or top layer. I adjust the extrusion multiplier (Flow Ratio in Bambu slicer) to get exactly 0.4 mm wall width (for a 0.4 mm nozzle). A micrometer is better than calipers for assessing this.

After building and ‘Klipperising’ my printer is set it up with the MK1 Califlower model and spreadsheet which corrected for a slight skew in xy as well as x-y scaling etc. Looks like it has been replaced with this https://vector3d.shop/products/califlower-calibration-tool-mk2

But I guess you didn’t get the Bambu to have the printer itself as the project as I did.

Quite right, Andrew … using a 3D Printer has been on my “bucket-list” for a long time and, quite frankly, I chose the Bambu on the basis that Vita brevis !

I am most grateful for your helpful observations though.
