Re: Which electronics is best for the E6D kraken

The on,y mod I saw on the duex4 is for one extra extruder to fix the noisy ground on it.
I will check the radds.

I am not familiar with the RADDS. The noise problems on the DueX4 don't actually stop you from printing. The main effect is to cause the apparent temperature to fluctuate, in particular when the hot end is at room temperature and the readings are most affected by noise. There are a few potential remedies:

1. If only one extra extruder is used, swap the bed temperature and second hot end thermistor connections. The bed thermistor is less sensitive to noise because of its lower value and lower temperature range.

2. Change the thermistor series resistors from 1K to 4.7K. This will reduce the impact of the noise, especially at room temperature. In time, DueX4 boards are likely to have 4.7K as standard, just as recent Duet boards do.

3. Move the smoothing capacitor(s) for the channels needed from the DueX4 to the Duet, as explained in my blog entry on dual-nozzle conversion for the Ormerod.

Another solution will be to use the Duet daughter board that RepRapPro is manufacturing and should soon have available. This design avoids the noise problems of the X4.
