Nice job! How did you do the pivot? Is it a tapered pivot like the Hardinge? bob |
| WeldingRod:
No, it's a shoulder bolt in a matching reamed hole. On the subject of 3D printing heights, I've been happy with the results when I measured it. Quantization errors shouldn't be cumulative (unless somebody blew it on the coding/math). Microstepping doesn't change the fundamental mm/turn, just electrically divides it. Surface finish on the top layer adds uncertainty. I could run out some test pieces... knowing I run my printer on freakishly thick layers. ;-) Sent from my SAMSUNG-SM-G891A using Tapatalk |

WeldingRod: I don't see how the slicing software can get a part height that will be consistently accurate. It's going to get really close, but I don't see how the part height couldn't help but vary by up to +/- one half the layer thickness. I guess it would depend on the slicing software you're using. I have a Prusa I3 clone so I'm using Slic3r that's been optimized for the Prusa machines, I don't print enough to be able to justify shelling out a couple of hundred bucks for slicing software. Don |

Ah, right! Unless your slicer is able to do partial height layers, you are going to get an integral number of them. I haven't heard of partial height layers as an option anyway. When your later height is small fraction as of a mm, it's not an issue relative to the xy accuracy. When you do like me and use 0.6mm layers, you've got to be a bit more tolerant. I'll see about some z axis tests tonight. Sent from my SAMSUNG-SM-G891A using Tapatalk |
