Most software parts are prepared, the weld control loop already works with 10us cycle time and ADC conversions running with DMA. Really nice microcontroller architecture, you set up everything, and then it will continuously update an array in memory with conversion results.

While waiting for the boards to arrive next week I have machined electrode holders from 6x12x35mm brass. What do you think about it (these are not the final screws yet)?
