DEFAULT_AXIS_STEPS_PER_UNIT you can get them from calibrating your stepper motors Being N the number of steps defined in stepspermillimeter in the firmware (X=80, Y=80, Z=2560, EXTR=777.6).N = 2560N = N*10/37.4The new value should be 682.67. (Z=682.67)calculating every axis for the precise value.
Thank you, i appreciate your help very much. i'm trying to improve my printer with a new bed and need some cooling system for stepper motors because they get too hot quickly after start printing for a few second.
Woohoo! thank you setsunakaede the source of problem is steps_per_mm setting of the extruder. I tried to feed manually from Repetier 1mm but my extruder feeded 1 cm instead so the plastic came out too much and it didn't melt fast enough. i calibrated it again and reuploaded marlin firmware now it works like a charm! you really made my day ;)
More details may help. I was the same problem as you, for me i forgot to set jumpers to 1/16 microsteps on the ramps1.4 board and increase some vref (potentiometer on the driver) what's your stepper driver? and make sure you didnt connect wrong wire on the motor.sorry for bad english
i just finished building my ewaste 3d printer thanks for your information about materials list it's very helpful. i got some problem about feed rate. when it starts printing every thing works fine then the nozzle stops to feed plastic. i tried to increase temp to 210 C but no luck. Do you have any suggestion?
