Anyone else have issues with circular errors? I’m going over my machine to try and get it to the level of engineering prototypes. Im a Mechanical Engineer by trade and just like precision. Example if i currently print a high res stl with a 20mm Dia cylinder It get a measured output of Max: 20.1…

So I believe in conclusion: yes in conclusion… and thanks to everyone who has / had input on this. Precision is a never ending task or goal. Items wear and the environment changes. But with work and time you can get to a very reasonable precision with the snap maker system. If you personally are…

Same issue shows up in a vase cylinder print. Max 20.20mm Min 19.95mm

The X axis and the Y axis are at or near the mins, correct? If so, what you are describing is backlash, which is the affect that I mentioned. It is very possible that your Linear Modules have either worn down a bit, or were not properly adjusted. There is an anti-backlash screw in each Linear Mod…

its not backlash its not an oval Its a flat spot on the roundness of the circle 1 flat spot random z seams. if you read the discussion you would of known all of this.

I have read the thread, and you are discussing multiple issues, not just 1 single issue. However, since you don’t want my help, I will step out. Best.

Im open to the help but but insisting it is something that we have tested. Confirmed and retested as a group isn’t helping. You have brought no new info to the table. You said to print in vase mode i did. Same issue. Using a dial indicator with 0.01mm resolution measures back to 0.00mm 75% of t…

Mxbrnr thoughts? [image] Back to printing: Lines Getting Started Than this issue is solved. @Linui this could be interesting for you, too. Recap: Linear advance, Junction deviation, accelleration, flow and speed really made visible differences. But the real problem wa…

So my single extruder prints a 20mm x 20mm cylinder showing a diameter variance of between 19.74mm to 19.92, widest at the z-seam; no calibrations of any sort done with the machine at this point (except bed level). So even uncalibrated I am getting the same 1.3% error you are. Slicer settings were 0…

Yeah in reality .18mm delta is not allot. Did you notice a flat spot like davidE1a and my self show? I mean if it was round and oval but smooth then my mind goes to like cnc-maker said back lash. But since there is such and abrupt change (on mine the max and min are only like 2-4 degs rotational …

Not to my eye, and watching the gauge change as it rotated seemed pretty smooth, more oval like, but I could be wrong.

yeah mine is more like a cam falling into place. pretty abrupt Thanks for the info.
