But reducing the multiplier from 1 to .95-.97 should have similar affect… speaking of which you mentioned the infill was affected by this, just increase the infill percentage?
Regardless, I’d try a better “known” object for calibration. A metal object of a standard width/diameter… I designed a thumbwheel that fits on a M5 socket cap. Not sure what type of socket caps are prevalent on the TAZ 6, but maybe that’s a better calibration.
Absolutely understand the need for accuracy. I use the multiplier to account for part accuracy (95-97% seems to be the sweet spot for my printer and eSUN ABS). There’s also a Horizontal size compensation setting in S3D… good for pre-designed STLs, but shouldn’t be necessary for original designs. I’ve never thought about infill as affecting the external dimensions… primarily for strength of part.
FWIW, if you’re printing ABS, the part will usually shrink… ~8% seems to be consensus. ABS is also malleable, and it should compress to fit.
Well… good luck on your quest for accuracy. Its a challenge and at some point its going to be a compromise.
I was thinking about this the other night… specifically the infill getting sparse when you decreased the multiplier.
I use the “Infill Extrusion Width” setting to create solid infill walls… mine is cranked up to 200%. I think 175% is enough. This results in an almost solid 1 extrusion width walls for infill… helps increase model strength legacy from when there wasn’t any diversity in infill patterns.
Looking at your expected versus printed dimensions you might try to re-calibrate the X&Y steps instead of the extrusion steps. The Z steps look to be within .5 % which is pretty good, but the X/Y look closer to 1%.
Hmm… ok. I’m not sure what “XY Adjustment” is in S3D… but you’ll be hard pressed to find a specifically “multiplier”, “underspeed” and possibly infill % in Cura… I don’t use Cura enough to know all the settings…
Note:I realize that Simplify3D is not an open software project and many will not find its price worth the investment. I’ll attempt to find a configuration of Cura that has the same effect so others facing my problem will have options.
The “dimensional adjustmet” setting seems to be unique to S3D… or I haven’t seen it in Cura or Slic3r. Its helpful for downloaded or pre-made STLs. Good compensation for the varied range of machine calibrations of designers.
If you haven’t, try creating your own fitment objects. Maybe a 10mm diameter peg, along with a corresponding ring / hollow cylinder which is 10.2mm I.D. (or try 10.1 I.D.). That would be the ultimate test of fitment.
Seems like Cura should have a similar setting; not sure how hard it would be to implement - I’m new to this slicer stuff and don’t even know the basic algorithms. Anybody know what it does? Actually thin the walls, or does it “inset” them a little?
