Section 1.8 Esteps and Flow Rate using Octoprint and Free Air Method

In this video I go over Section 1.8 of Luke's Guide, Esteps and Flow Rate using Octoprint to save the new ESteps. This can be done with any software that allows you to connect to the printer, as long as you have a firmware that allows saving to the EPROM.

GCode Used in this video:
M503 - Used to see the current settings of the printer, and get the ESteps

G1 E100 F100 - Used to advance 100mm of filament through the extruder

M92 E### - Used to change the ESteps to the value represented with the # symbols. For example if we want to change it to 100 steps, the code would be M92 E100. 95 ESteps would be M92 E95.

M500 - Saves the changes you made into the EPROM.

EStep Calculation:
100 (commanded Steps) divided by 98 (actual steps taken) = 1.02
1.02 x 93 (Current ESteps) = 94.86
95. is your new ESteps if you round up

Flow Rate Calculation using new .8 walls on the cube:
Value of all 8 measurements divided by 8 = Average Measurement.
.80 divided by average measurement multiplied by 100 = New Flow Rate.

Example:
.78+.80+.76+.79.+.80+.81+.75+.78 - 6.27 Equals Total Walls Measured

6.27/8=.783 - Total Walls Measured divided by 8 (8=total measurements taken, 2 on each side of the cube)

.8/.783 = 1.02 - Wall thickness (.8) divided by Average of Total Walls Measured (.783)

1.02x100=102. = 102 is the new flow rate.
