step_mm failure #589

eeerfan commented 8 years ago

Hi dears I try to calculate my step_mm in this way: StepsPerTurn = 400 //my stepper motors are 0.9 degree BeltDistance = 2.0mm // GT2 belt GroovesInPulley = 10 // FOR ME IS 10 Substepping = 16//for a 1/16 step needed StepsPerMM = StepsPerTurnSubstepping/(BeltDistanceGroovesInPulley) = 40016/(2.0*10) =320

it should be noted i use drv8825 stepper motor driver. but when i add this number for step per mm my printer dosent work correctly. what can i do???

This is not enough information for us to help you troubleshoot, and it pretty clearly isn't a Repetier firmware issue. You should post pictures of your hardware and a description of your troubleshooting steps taken so far on a general help site like the RepRap forum.

Did you change it in eeprom or configuration.h? EEPROM would be the right place.
