Since you have FSR's connected to the duet, the i2c and blue wires aren't used anymore. The i2c wires were the communication to the accelerometer on the He280, which has been replaced by the FSR's which don't need to be talked to. The blue ps -on wire was the output pulse from the accelerometer to t...

I've been thru what your doing in the last few weeks, tried both accelerometer interface boards and couldn't get consistent triggering and "triggering before errors" and I finally put the FSR's under the bed. After tweeking the config line, it works like a charm. I printed the FSR mounts, ...

Hi 626Pilot, been reading through all these threads and found these pics from last year. Any chance the files are available for download, really eager to put my 360mm magnetic arms on my v2 with the trick laser trucks. These look really good. Thank You for all you do here [img]https://photos.smugmug...

Thank you, didn't think it was the fuse, but it was. When it first happened the bed temp was still working so I thought I blew the input not the fuse. Still a little puzzled about it.

Just blew up the T0 input on the duetwifi. My machine has the HE280 hotend and I forgot the connections for T0 are keyed to provide ground to the accelerometer board. 12V backfed to the analog pin on the 3.3v atmel chip and the input in no longer. Just a warning to others.
