Today I got the whole motion control chain from EMC2 on the pc through the Mesa m5i20 servo-card, homemade optoisolator card (far right), PWM to analog filter (small board on the right), servodrive (middle), powerstage (middle left, with heatsink), through to the motor (left, a Sanyo P5 1kW servo) working !
This is truly Open Source cnc: EMC is obviously an OpenSource project, but also the FPGA configuration on the m5i20 is published under the GPL, and my servodrive code will be available when it fully works.
The picture might seem messy with a whole lot of wires - but I can assure you that it's all very organized... 🙂
