I just set up my Ramps 1.4 board with a few steppers, using A4988 drivers. However, it seems that my microstepping isn't working, as my calibrated EEPROM settings are 2.5 steps/mm for both steppers. I've heard about needing to attach jumpers under the drivers in order to get this to work, but could someone please explain further? Or let me know what I should be doing differently. Thanks a ton!
Just a note- the steppers are working perfectly fine; they respond to commands sent from repetier host (the firmware is also repetier) but simply are not nearly as precise as they should be.
