Stepper Calibration (Current) | |
============================= | |
Check the Vref of your steppers first, They should be at around 450mV for the X,Y,Z axis. And 700mV for the extruders. | |
You need a multimeter, a small screwdriver, a steady hand and a lot of patience. With the BI on its side, power it up. Look at each of the drivers (that would be a row of 4-6 identical daughter boards on the RUMBA board. There is a small (really small) potentiometer, that's the screw. Look for the point labeled GND. Take the ground lead from the multimeter and touch it to the GND point, then put the hot lead of your multimeter on the screw -- that will give you the current voltage. | |
For safety's sake, turn off the printer before adjusting the pot. Use a small screwdriver to adjust the pot. A tiny movement may make a big difference in the voltage so go slowly. Check the voltage. Adjust. Check again. Adjust.... | |
