Still under extruding[emoji19]

So I just replaced the Hobbed bolt that had a nice notch worn in it from when I started using repieter and it randomly would just speed up the extruder in a middle of a print and grind filament (witch happened to be colorfab xt) I am still getting random under extrusion measurements. I keep going through the calibration steps that have you measure 120 mm and extrude 100. No matter what I change the e steps to it's always off 3-5 mm (I end up with 23-25mm exposed), and I have moved it at least 30 points. I initially had it calibrated at 755.43 on the estep and even at 789.97 it still under extrudes. I have done the atomic pull method to clean out the hotend and changed nozzles twice as well has pulled the whole assembly apart.

What else could I be missing and is there something else in the eeprom that I could have changed by mistake that would have caused this issue?

Thanks for that advice. Still having trouble with extrusions, won't stay consistent



I have a tech appointment with Robo, not sure what good it would do at this point though
