I am working my way through calibrating my printer and now need to work on overhangs. The tuning guide suggests tweeking the BRIDGE FEEDRATE MULTIPLIER parameter and I can not find anything that comes close to matching that terminology in Slic3r which is what I am using (along with Pronterface to drive Marlin). Obviously, any overhang printing advice would be appreciated!

Thanks for any guidance,
Wisar

slic3r defines the bridging speed in the speed section on the print settings tab. You can define a speed outright but can't define it as a percentage of your speed

The comparable setting in Slic3r would be "Bridge flow ratio" under "Advanced" on the "Print Settings" tab. It's action would be the opposite of "bridge feedrate multiplier" though in that you would decrease it to prevent sagging (if calibrated correctly).

Thanks, I see the appropriate option and will give it a try once I replace a blown extruder thermistor :-(
