Ok, I have been trying to fine tune my esteps as the extruder pulls in just under the required ammount. I trued the command M92 Exxx as per the wiki and this did not seem to change anything. I have also tried editing the value in the firmware, though this was set to 875 but the wiki said the default is 980 any ideas?

ok seemed to have fixed it I altered the e steps based on the assumption that it was set to 980 even though it said 875, and it seems to have worked
