Thanks for the input. I was using ABS (usually do), not PLA, but I will try reducing the temperature the next time I put the 0.8 mm nozzle on the machine. Right now it's back to 0.4 mm.

Thanks, I'm using a smoothieboard, so the firmware is smoothieware, but it shouldn't matter- the gcode is almost identical to that used by Marlin.

I am used to using volumetric extrusion in Slic3r and now trying in Cura. I slice and save gcode to SD card, and print from the card. In Slic3r when I select volumetric extrusion, it calculates extrusion based on a filament diameter of 1.128379 mm. Before I print the gcode I enter the actual filament diameter into the printer's controller using the LCD panel/rotary encoder. The gcode file can be used with any diameter filament, as long as I enter the diameter at print time. What exactly does Cura do with volumetric extrusion? If I enter a filament diameter in Cura will it be ignored or w

I've been struggling with print quality using a newly installed volcano with a 0.8 mm nozzle. The extrusion stops a couple mm before the end of a layer and leaves gaps in the prints. It's as if coasting were turned on and set too long. I tried turning on coasting and setting a negative value, but Cura won't slice when I do that. How do I get it to extrude right to the end of the line? There is also a small gap that occurs during printing (marked "?") that I'll tackle after I get the bigger problem solved. I had a similar gap at the start of each layer, after a relatively long travel mo
