Bridging

[tonybuckley]

So may I ask about bridging on the i3v.

This seems a bit of a minefield. I have read sites that say, the temp should be hotter than normal, that is should be cooler than usual. I have read sites that say you should set for a fast speed, others say set a low speed.

I have been playing around to get this working on a very simple 50mm x 10mm bridge. All I have done so far is play around with the temps - started at 225 and reduced gradually down to 180 but they all came out very similar.

My next play would be adjusting the speed. I am using 150mm/s which is the default setting from Colin's config.

So any recommendations to speed me up?

The machine is 8" i3V, my hotend is E3D-V6 and I am printing 1.75 PLA. Bed is heated to 70.

Too many variables.

Thanks!

I have success with a faster bridge speed and using a cooling fan.

Thanks - not explored a cooling fan yet.

Also, I lowered my extrusion multiplier when bridging. This makes it so the filament has to be pulled tight when it bridges to help it from drooping and the cooling fan helps it cool faster to again help it from drooping.

A cooling fan will make the biggest difference in bridging.

How does one achieve that on Slic3r?

in Slic3r 1.2.9 it's under filament settings.

So it is - thank you. Mine is set to '1'.

That is shockingly stunningly amazing! I will get a fan.
