Different times of day, no electronic mods (beside 12V stepdown not working on my board to be replaced) and both prints about the same time of print.

Use of USB power is very marginal due to insufficient dropout margin in the 3.3V regulator, so it's probably best to get RRP to swap your board as soon as possible. Some of us (including myself) experienced print hangs until we made some mods to the electronics, although I can't say there is conclusive proof that these mods are required.

I haven't had much time to play this week, but I did get one more random lockup around two hours into a three hour print - despite suppression of flyback on both heaters and an "apparently good" 5V rail from the on-board Buck regulator. So that's twice now since cleaning up the flyback issue. This is still a significant improvement over the stock design.

Hi Markus, interesting about the ferites on the USB I posted some time ago that I experienced problems with a laptop + USB +mBed module and ferrite beads were essential, so I will now add some, I use RS309 7940 [uk.rs-online.com] or other similar products. I find the laptop is generally not earthed even with the PSU plugged in (the metal work often floats around 100VAC (at a high impedance) as can be measured from an uncoated screw and a known earth and this acts as an arial injecting noise down the usb lead into the target.Quote

Hi Treth,
For the time being I added two ferit cores (each at the end of the USB-cable) which I had lying around.
It _looks_ like this helps. I can switch on and off the soldering iron without any freeze afterwards. Even when the cables (USB/ soldering iron) are lying crossed/ above each other.
BTW: It looked like the print hung more likely when I switched the soldering iron OFF.
Markus

You may also consider placing a ferrite core on the Vin white power lead at the DUET, I would try just Vin, but you may want to check around both wires. This would at least try to filter at the closest point you can get to the electronics.
