At a loss (3 replies)

So my printer has been running very well lately on all prints.

I have my e calibration perfectly, I double checked it with 30 and 50mm of extrusion and measured it perfectly.

I have double checked my measurements of my filament, and it is a very consistent and accurate 2.9 - 2.92

Other prints before and after that were smaller were working perfectly, very accurate.


So when I tried to do this larger one 150mm x 175mm, slicing in slic3r 0.99, running at low speed, I noticed I am extruding waaay too much filament.

The first time I ran it I used a 1 for the extrusion multiplier, as my wall thickness test was fine for the 1 in this field.

I noticed a crazy amount of extra filament on this print, stopped it half way through the second layer.

I changed to 0,9 in filament extrusion and re-sliced and printed.

Here are some pics of the second effort.

As mentioned, I ran another print afterwords, much smaller, about 30mm x 75mm x 50mm height, and it worked perfectly.

Some other settings: 0.35mm nozzle (buda 1.3) ABS, 0.3 layer height.

Here are some pics, at a complete loss, any ideas on where to look I would greatly appreciate it:
