How does nozzle size affects bridging capabilities? My printer came has a 0.35mm nozzle, and it only recently struck me that this could be affecting my bridging, which I never really got that great. Perhaps bridging would work better with a bigger nozzle, like 0.5mm? It seems to make sense - the thicker extrusions should be stronger. But has anyone tested? (I use Slic3r.)

I started out with a .35mm nozzle but as time went by i moved to a .5 and even a .7mm nozzle. I did this primarily to reduce print times . I have never had trouble with bridging reasonable spans but i would have to say a larger diameter nozzle may improve performance.

Pretty nice bridging going on there. What software are you slicing with? Also, it sounds like your cooling fan has some trouble getting up to max speed. Is that right? I've had some trouble with that myself, I think it's because of vibrations in the fan itself.

+Ketil Froyn Thanks, I thought this one went really well. I use Slic3r for slicing and Pronterface to talk to the printer. I've had a few fan issues over the course of owning this machine, and I think you're right the vibrations have something to do with that. Also though, I have had some power issues specifically with the bed heater and fans- I don't think these early generation M2's were equipped to supply enough power to these extra components.

"Everyone's entitled to their opinion. But you know what you're not entitled to? You're not entitled to your own facts."
Vaccine-autism claims, "Frankenfood" bans, the herbal cure craze: All point to the public's growing fear (and, often, outright denial) of science and reason, says Michael Specter. He warns the trend spells disaster for human progress.

After a long running discussion, Slic3r will calculate flow using the same formula Nophead has published on his blog a few years ago (which it did already in some cases). But the difference is minimal, and Slic3r 1.2.0 will have other interesting features too, for example to get correct dimensions of parts. This will be interesting to try out!
I hope someone here can help me. I have attached a couple of images to explain. My inside dimensions (like A in picture) are printing too small. Outside dimensions (B & C) are all printing good. What could be causing this? Part designed in SolidWorks exported as STL... Richard

It's going to be interesting to test slic3r's new 3d honeycomb infill pattern on some prints.

Nice! Very much like the idea +Gary Hodgson blogged about a while back.
