    D 粒粒都係差唔多既地方出現. 會唔會出絲唔順?  有冇調過出絲量?

Ching,你用什麼Control Board, Stepper and firmware?

    轉咗E塊板＋Kossel mini ＋42 stepper！同mega 256 + Reprap Ramps1.3 一樣！
行Marlin！

明顯熱床升温好咗！ 其他好處有待發掘！

    What control board are u using?

verystrong1991

用arduino 2560 +ramps咋
firmware係marlin

I also post this topic on the other forum!



Another possible explanation is the drv8825 blanking time (missing microsteps in the low part of the voltage range).

Take a look at the excellent analysis here: [cabristor.blogspot.ca]

The short form: Put a pair of back to back diiodes in-line with each coil of each stepper motor. The original author recommends 4 diodes for each coil, but in my tests a single pair seemed to do the job.
