I'm trying to do the E calibration on my Printrbot. I extruded my 30mm and did my measurement, and came up with 28.6mm, so I did the calculation and put my new value into Slic3r, sliced and loaded the file into Prontoface and got 27.76mm, then 27.81, then 27.52, then 27.74, then 29, then 28.53. So clearly I'm doing something.
Currently my Start G-code in Slic3r is:
G28 ; home all axes
M92 X64.8592 ; calibrate X
M92 Y64.8592 ; calibrate Y
M92 Z2387.0719 ; calibrate Z
M92 E600 ; calibrate E
The wiki page for the getting started guide mentioned something about setting the new E value to active, and that I would need to either "slice and print an object" or "send the command to the printer using the Pronterface console".
I understand that changing the M92 for E in Slic3r does not affect the printer until it starts printing. I entered M29 E600 into the "send code" box on Pronterface. When I click send the extrusion motor runs backward and does not stop. I have to turn the power off in order to get it to stop running backward.
How do you calibrate "E"? Obviously I'm missing something.
