I’m clearly missing something here. Following the instructions here http://ohai-kit.alephobjects.com/project/extruder_calibration/ on calibrating my extruder on my TAZ4.
Basically all we are doing is working out a two ratios correct?
Estep value/100mm=Current Estep Value/Measured filament distance. Then solve for Estep Value.
When ever I do this and input the new estep value my measured filament distance is no where near the 100mm.
Extruding at 100mm at 100mm/min
Estep 851.5 gives me 98.5
Estep 852 gives me 98
Estep 853 gives me 98
Estep 870 gives me 109 (853100)/98=870 (Way over shot it)
Doing the math again (870100)/109=798… but it was whithin 2mm at 852. Why would I go back to 798???
Just doing a bunch of test prints and saying forget the math I was able to dial it in with an Estep of 863.7. Which makes sense its between 850 and 870.
So am I doing the math wrong or whats the deal?
