Hm. Going back and rereading all of Ed's responses in this thread, I think there is some misunderstanding here. I certainly didn't understand him to be saying what you think he is saying. Perhaps the confusion stems from his use of the term "thinwall boxes"; when he says that, he is talking one per...

At least for me, I'd rather do the tuning once , then spend the rest of the year cranking out parts that fit and work as expected. The designs all assume that ±0.20 mm tolerance I mentioned. To get tighter tolerances, I'm willing to ream holes, mill surfaces, and hand-finish edges: all operations t...

Just to reiterate - my thin wall test is checking out at 0.4mm (+/- 0.01), and the height is 2mm as expected. As I explained, I reduced it further because a 2mm thick wall in my model was coming out too thick, and my reading of Ed's reply to that was that was the right thing to do. jsc replied that ...

OK - It's just that I seem to be getting a different opinion from jsc :). Tuning the extrusion multiplier based on a thicker wall is OK? So, I'm good with putting it back to the lower value (as my prints worked fine) - and I *think*, but could be wrong, that they're turning out fine with the same mo...

Now you're close to the spirit of the thing! You adjust the Z Offset to put the nozzle at the correct mechanical Z position, set the actual filament diameter, adjust the Extrusion Multiplier so the extruded thread matches the slicer's expectation, then dink with your models to get the desired clear...

You are measuring a 2mm wall, so you are measuring multiple perimeters at once. In order to measure just the extrusion actually, you should measure a single thickness wall. Well, that's what I was doing and getting 0.40mm (with maybe a +/-1 0.01mm discrepancy at worse) with both the modified E valu...

:D. Did a double take on the current project and decided to tweak this setting first. Curious thing - the original print was working great, but the measurements would suggest that I was over extruding as suggested. For example, a 2mm wall was coming in at 2.3mm. When I switched the E value back and ...

Yeah - when I lower it, it wasn't sticking. OK - I'll try with the default E steps again and try the 0.9 once I'm done with my current project (it's kinda finely tuned involving interlocking parts - feel that messing about with the parameters now could mess me up). As for Charizard not being flat on...

Many thanks for the feedback PcS. Nice print too :). I really don't have bed adhesion issues that I'm aware of - the only time I had issues was when I reduced the extrusion multiplier. Or do you mean that the toppling of the supports is indicative of the multiplier being too high? The thin wall test...

Looks to me like this should work quite well. I created a small connector for the pins like: relay-disconnected.jpg Wired up, it provides a surprisingly robust connection - I can comfortably pick it up by the wires without them falling out or losing connection with the pins: relay-connected.jpg Mode...
