NOTE: the workflow for calibrating e steps just says to set extruder speed to 100. It gives NO units. Since they are referring to using Pronterface, and it’s units are mm/min, you can infer that they mean 100mm/min. This is quite slow.
If you are actually using Pronterface, it will be pretty straightforward (even for a Noob like me). If you are doing this in Cura, the units are in mm/s, so the equivalent would be between 1 and 2mm/s. (I don’t know if the gcode listed above will accept decimal points, but the actual equivalent would be about 1.7mm/s).
If the Lulzbot tech support folks are monitoring this, I’d suggest adding the units (mm/min) to the workflow description (step #4 here), and perhaps pointing out that folks should check whether they are setting mm/s or mm/min if they are using some other software. My initial attempts to calibrate e steps by hitting the 10mm manual extrude button in Cura 10 times were not getting me consistent results. I wonder if speed was an issue?
