Extruder calibration problem

Hi there!
I have a weird issue that I hoped someone may shed some light on!

I am trying to calibrate my extruder, at the factory firmware setting (320 or something) it shot out about 320mm of ABS, so I adjusted it to the calculated ratio (I only wanted 100mm). The problem was it seems to have very little affect on the output.

I request 100mm of cable and still get around 300mm of 1.7mm outputting, even with a resolution of 10 steps/mm.

Does this make any sense to anyone?

I am using repetier firmware and host, RAMPS 1.4 with A4988 drivers. Microstepping 1/16. 11mm hob directly driven by stepper, feeding to a bowden tube. I have tried a new driver. I have tried regenerating the firmware from Repetier, and even manually entering the value into Arduino IDE (successfully)

Thank you again for everything.

The extruder steps/mm are stored in the eeprom which takes preference over what you set in config.h

You can edit the eeprom directly from repetier host (config menu) or
Send following codes to printer
M502 ;read config settings
M500 ;store settings to eeprom

Thank you so much!
Fixed in 5 seconds, you just saved me heaps!!
