Hi
I have built my own machine, it uses mk8 style extruder.

What is calibration method for estep/extrusion multiplier etc?

Just true estep work or does it need further calibration?
I used to do calibration in 2 ways. 1 is measuring the thin wall (printing solid cube hollow with no top/bottom and single wall) and make the extrusion equal to extrusion width (which I generally used to keep as the nozzle dia)
or other way just keeping true estep and keeping extrusion width to auto.

What method is correct for simplify3d?
I think changing extrusion multiplier to get the extrusion width to what is auto set looks correct method.

Thanks in advnace

PS I don't like 'eyeballing' method. I like to have solid math behind it

This thread talks about the method for changing steps per mm for printers using Marlin or other RepRap firmwares, if you're using Sailfish it's doable just a bit more complicated. http://forum.simplify3d.com/viewtopic.php?f=8&t=1189.


To calibrate, I'd recommend calipers and printing out a calibration cube. I traditionally use the calibration cube steps 5 mm off of thingiverse and measure using calipers, http://www.thingiverse.com/thing:24238

These Calipers are only 12 dollars and work great for measuring
