I also tried bossac cmd line but it just says erase flash but doesn't do anything more

chrishamm

Well, sometimes USB3 ports don't work and can cause various problems. Try flashing it over a USB2 port if possible. If that fails, I suggest you try the same procedure again on another PC and/or attempt to boot from a Linux live CD like Ubuntu.

@chrishamm ok thanks I'll give that a try this evening

i just noticed that the main atmel chip is getting so hot it burns my finger to touch it

What type of Z probe is it, and how did you have it connected to the Duet?

PS what is the PCB revision number of the Duet?

@dc42 hi its was the smart effector connected to the 4pin header on the duet board. The board is v1.01

It sounds to me that there has been a transient on the +3.3V rail which has damaged the processor (but not wrecked it completely) and the SD card. I guess that transient was caused when the Smart Effector was unplugged.

We may have some refurbished v1.01 boards available. If you are interested in buying one at a special price to replace your board, then please email info at duet3d dot com.
