I've just finished making the toroidal power supply as per instructions by your posts here in this forum. Working well. Here is the video testing one of the four steppers in slow jog, then fast jog and then fast rapid at 3000rpm.
m_c will be partial to the lovely control board. The driver is an EM806. The microstep was set at 1600
The transformer is 24V-24V, it gives me 70V output with the driver connected. 3x capacitors 4700uf, 100V, 105deg. Bleeder resistor is 3K9 5W with Led in series. With nothing connected is discharges the capacitors completely in around 4 mins. With one driver, in 7 seconds. Slow blow 5A fuse in the 240V input.
